Among the many imported projects, the development of the production technology of automobile door and window sealing strips is the most representative. Through the introduction of sealing strip production lines from Japan, Germany, Italy, Britain and other countries, up to now, domestic manufacturers have introduced more than sealing strip production lines. In addition to pure rubber sealing strips, sealing strips of various composite structures, metal skeleton and various rubber composite sealing strips, rubber and plastic composite sealing strips can be produced. At present, the overall level of China&#;s sealing strip production technology has basically reached the level of foreign countries in the s, and has become a grouting pipe. Because some projects are not easy to detect when they are manufactured, and the quality of the grouting pipe as a channel for testing instruments has become crucial. If the quality of the grouting pipe is poor, it will bring many hidden dangers. Steel grouting pipe material, steel saving, impermeability, pressure resistance and high strength, is generally used for post tensioned reserved holes in prestressed structures. When the grouting pipe is used, it can be directly bound to the reinforcement framework. Because the grouting pipe is very light, it is very convenient to operate. However, attention should be paid to the balance of its axis during installation.Two convex grooves are planned at the end of the bell end of the double seal clamp grouting pipe,Saint Vicente de MoraviaGrouting small conduit and advance anchor rod, and the convex grooves are equipped with sealing rings. During installation, the spigot end of the product is stabbed into the bell end. The grouting pipe then kneads the two convex grooves together with a special hydraulic clamp, and the pipe at the kneaded part is shortened and deformed after being stressed. The outer pipe between the two convex grooves is deeply embedded into the inner pipe, and then the connection of the product is completed; After being kneaded, a rubber sealing ring is deformed and pasted between two layers of pipes, which plays a double safety sealing effect.Saint Vicente de Moravia, The grouting water ratio of grouting construction is .: ~ .: (i.e. the weight ratio of water and cement), and the principle of 'dilute first and then dense' is adopted. Por early strength Portland cement is used as the cement. Before mixing the cement slurry, the quality of the cement shall be checked. If it is found that the cement is hardened and deteriorated or fails the test, it shall be discarded to prevent the quality of pile end grouting from being affected by the deteriorated cement. The grouting time should be - days and - days after the completion of single bearing platform pile construction.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole, the Jiangsu acoustic tube can be used normally in the process of application, and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device, the resistance of Jiangsu acoustic pipe will appear in the process of application, resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, it is necessary to pay attention to the method of the device in the process of the device, so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, some of which are straight to the nozzle and there is a concave appearance on the adjacent side. This kind of wrinkle is mostly in the shape of sharp ridges, and often occur symmetrically at both ends of the center line, in the shape of 'eight'. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, and some occur on the outer arc surface.Kaesong Super City,Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.Welding is strictly prohibited during use, because the strength of the welding point is much lower than that of the steel itself, and it is easy to cause broken wires at the welding point during tensioning. When the grouting pipe adopts circular reinforcement arrangement, its bending radius shall not be less than times of the diameter. The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality, when you choose the upsetting head anchor, you should explain it in detail to the manufacturer in the order.In China, the types of grouting pipes are relatively complete now, from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, different types of grouting pipes are selected, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.

It is proved by experiments that the bearing capacity of the same bored pile with and without grouting pipe is separated by %. That is why more and more bored piles and grouting pipe grouting are used more and more widely in China When the concrete strength can ensure that its surface and edges are not damaged due to formwork removal, the side formwork can be removed.However, not all grouting pipe products can achieve this effect. Some inferior grouting pipe products not only fail to achieve the expected effect in use but also have problems such as low grouting efficiency, pipe burst and pipe bending, which seriously affect the grouting effect of the grouting pipe and the progress of the whole project. The quality of grouting effect comes from the selection of high-quality grouting pipe products. Shengpeng grouting pipe is a good choice for you to choose grouting pipe products because of its high strength, awesome, simple connection and high cost performance! Grouting pipe the grouting pipe is a kind of geosynthetic material formed by ultrasonic welding which is composed of a steel plastic composite reinforced belt (built-in high-strength carbon spring steel wire (stress material) and wrapped with polyethylene resin (protective material) and arranged at right angles to the plane longitude and latitude. It is a comprehensive product of existing rigid reinforcement (flat steel strip, ribbed steel strip, galvanized steel strip, stainless steel strip, reinforced concrete strip, plastic grouting pipe, warp knitted grouting pipe, etc.). Because of its high tensile strength, low elongation (≤ %), small creep, and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, restrict the lateral displacement of the soil, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation and improve the overall performance of the foundation; It can be widely used in road engineering, railway engineering, retaining structure, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking.Quality assurance, Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, screw connection, flange connection and other methods. It has a reliable anti-seepage effect during concrete pouring. Two convex grooves are planned at the end of the bell end of the high-strength double seal clamp type acoustic measuring pipe, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect. It is a thermoplastic material, which can be processed and formed many times, yze what causes the pipe blockage. For the pipe blockage of hard objects, you can poke with steel bars according to the depth, or bind a slightly thicker steel bar with steel wire rope. For the pipe blockage of soft objects, you can use the air compressor pipe to open the air compressor for blowing. Be sure to note that the water in the pipe may rush up like a fountain to pour water all over you! If it is slurry leakage and pipe plugging, there is no way to open it. We can only communicate with the testing personnel to change a testing method,Saint Vicente de Moravia50lead small conduit, such as low strain and core drilling method! Other uses of the grouting pipe: in addition to being used as a detection channel and replacing part of the reinforcement section, the grouting pipe can also be used as a pipe for grouting at the bottom of the pile. Experiments have proved that the bearing capacity of the cast-in-place pile treated with the grouting at the bottom of the pile can be greatly improved. At the same time, it is necessary to take measures to punch through the pipe at the defective part to be grouted. Grouting pipe is specialized in the production of grouting pipe (ultrasonic detection pipe) for bridge pile foundation inspection. The product conforms to the industrial standard steel thin-walled grouting pipe for concrete cast-in-place pile and its use requirements (JT / T -, which was tried out by the Ministry of communications of the people&#;s Republic of China on April , It can not only meet the requirements of the standard, but also greatly improve each index, and obtain the inspection report of Hebei Road and Bridge Inspection Center.

The use of grouting pipes has become indispensable in modern building construction, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage, because China&#;s ancient buildings are very technical in construction. In China, before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible.management, Glass fiber grouting pipe is a semi-rigid product made of glass fiber as raw material high-strength alkali free glass fiber through a certain warp knitting process, and fiber filament coated on both sides.It depends on what kind of syrup you inject. What kind of construction site. There are two kinds of general grouting pipe inner diameters and The diameter of the hole is -mm at most. There are also about mm. The length can be matched according to the construction requirements, without loss.Saint Vicente de Moravia, we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed, it will be blocked by cement slurry during construction. At this time, it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes.The mesh structure of the grouting pipe can make the pore water pressure dissipate faster, and effectively accelerate the drainage and consolidation of the soft soil of the foundation. This is very important for strengthening soft clay foundation. Precautions for grouting pipe installation: when tensioning the prestressed reinforcement, it shall be loaded from zero to the initial tension at the starting point of the measured elongation value and then loaded to the required tensioning force by stages; Stress control and elongation check shall be adopted for tensioning management of prestressed reinforcement. The allowable deviation between the actual elongation value and the calculated elongation value is - % ~ + %. If the value is exceeded, the tensioning shall be suspended; Tensioning can be continued only after taking measures to adjust; If the elongation value is too small, over tensioning measures can be taken, but the tensioning force limit shall not be greater than .fptk; In the multi wave curve prestressed reinforcement, in order to increase the tensile stress at the inner support and reduce the tensile stress at the lower mouth of the grouting pipe after tensioning, the technology of over tensioning and loosening can be adopted; The duct grouting shall be dense, and the strength grade of cement slurry shall not be lower than C. Before grouting, the duct shall be wet and clean,Saint Vicente de MoraviaAdvance small conduit support, the grouting shall be carried out slowly and evenly without interruption, and the exhaust shall be smooth. If the hole is blocked, the grouting port must be replaced, but the cement slurry injected for the first time must be discharged to avoid gas between the two grouts. After the holes are filled and the exhaust holes are closed, the pressure should be increased to .-.mpa, and the grouting holes should be closed later. The grouting pressure of the vertical duct shall be determined according to the grouting height; For the duct grouting of multi span continuous prestressed tendons connected by connectors, one span shall be grouted after tensioning, and it is not allowed to grout once after all the spans are tensioned; The exposed length of the prestressed reinforcement grouting pipe after fixation shall not be less than mm, and the grouting pipe shall be protected with end sealing concrete. When it needs to be exposed for a long time, measures to prevent corrosion shall be taken; When the steel strand has floating rust, please remove the floating rust and dirt of the steel strand at the fixed clamping section of the grouting pipe and its outer end so that the floating rust and dirt will fill the red groove of the clamping piece during installation and tensioning and cause wire sliding; The tool clamping piece is three pieces and the working clamping piece is two pieces. The two cannot be mixed. The working grouting pipe cannot be used as a tool and the grouting pipe cannot be reused; The grouting pipe shall be kept properly and shall be free of rust, when the prestressed tendon is long and the grouting pipe must be repeatedly tensioned and fixed water and other sundries during use. The working clip can be used after removing the foam in the packaging box. However, it is recommended to apply a small amount of lubricant (such as withdrawing the grouting pipe) in the conical hole of the grouting pipe plate, which is not only conducive to the follow-up of the working clip and withdrawing the grouting pipe, but also conducive to the multiple grouting pipe fixation of the grouting pipe; The outer surface of the tool clip and the inner surface of the conical hole of the grouting tube plate shall be coated with lubricant before use, and the debris on the clip surface shall be removed frequently to make the grouting tube flexible. However, when the clip is cracked or the tooth surface is damaged, it shall be replaced and shall not be used again; Safety measures shall be taken during tensioning, and no one shall stand after tensioning the jack; The grouting pipe solid system shall be used together and shall not be mixed with other systems. If the static load test is to be conducted, otherwise the solid performance of the grouting tube will be affected; The pile foundation grouting pipe is an important channel product for pile foundation depth detection. It has two main s, one is as a channel, and the other is as a pipe for grouting at the bottom of the pile. The cooperation Specification between the saddle profile on the horseshoe of the grouting pipe and the core is too low. When the outer mold and the horseshoe surface are fitted together, the gap is larger than the thickness of the pipe wall, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.
