Low cost, fast time, free from climate and place constraints.The grouting pipe shall be cut with a toothless saw (grinding wheel clamp). Cutting by electric or gas welding is easy to damage the surrounding surface and cause local heating at the end, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.Abquiki,[] further, the cutting rotating device rotates the cutting blade and pulley through a socket wrench to cut the casing wall. The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall.Andilamena,When the grouting pipe is installed, the axis deviation shall be ≤ cm, and the bearing capacity of the support joint shall meet the design requirements. When connecting the grouting pipes, bolts must be installed symmetrically and tightened in sequence. Meanwhile, in order to prevent excessive deflection of the grouting pipes when axial force is applied, the deflection must be corrected to the horizontal before axial force is applied.The grouting pipe without shaft roll packaging is tapped and paid off from the inner ring in the vertical state, and the drawn out pipe is spring shaped and automatically straightened. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, otherwise fried dough twist or disorder will occur. 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 overhead type is a special rack installed at the bottom of the driving head and connected with the wellhead tensioning equipment.

It is a thermoplastic material, providing convenience for hot melting and electrofusion connection of pipes. The distance between measurement points is cm, and when abnormalities are found, it is encrypted to cm.The foundation pit excavation shall strictly follow the principle of 'layered excavation'. The support erection shall be closely coordinated with the earthwork excavation. During the excavation, the earthwork near the grouting pipe shall be excavated by the central trenching method to prevent the machinery from colliding with the support; The earthwork near the slope protection pile shall be excavated manually with small machines and tools. It is forbidden to collide with the grouting pipe and bored pile by mechanical excavation. After the earthwork is excavated to the design elevation, the grouting pipe shall be erected and prestressed in time to reduce the exposure time without support.Latest quotation,The following aspects shall be paid attention to during the construction of grouting pipe: when the construction personnel are binding reinforcement and erecting formwork, reliable fixation measures must be taken for the buried grouting pipe to avoid displacement during concrete pouring and ensure the correct position of the grouting pipe in the concrete. When fixing the grouting pipe, only the allowable part of the grouting pipe can be perforated, and the body part shall not be damaged. The grouting pipe shall be fixed according to the construction specifications required by the design. The common fixing methods are: using additional reinforcement; Fixed with special fixtures; Fix with lead wire and formwork. No matter what fixing method is adopted, without damaging the effective part of the grouting pipe so as to facilitate concrete pouring and tamping. During the construction of the grouting pipe, there are many sharp stones and sharp edged reinforcement in the concrete, so when pouring, vibrating and positioning the grouting pipe, attention should be paid to the impact force of pouring and vibrating, so as to avoid piercing the grouting pipe due to excessive force.?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, the overall level of China&#;s sealing strip production technology has basically reached the level of foreign countries in the s rubber and plastic composite sealing strips can be produced. At present, 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 which has the characteristics of thin pipe wall, 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.The quality of the steel upsetting head of the grouting pipe is not directly related to its own quality, but the excessive strength will be harmful to the quality of the upsetting head. Therefore, when you choose the upsetting head anchor, you should explain it in detail to the manufacturer in the order. The grouting pipe shall be cut with a toothless saw (grinding wheel clamp). Cutting by electric or gas welding is easy to damage the surrounding surface and cause local heating at the end, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.

The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes, which can be distinguished from different angles, including the following. According to the type of reinforcement of the grouting pipe,AbquikiAdvance support small conduit, it can be divided into the grouting pipe of thick reinforcement of the grouting pipe, the grouting pipe of parallel reinforcement (wire) bundle of the grouting pipe, and the grouting pipe of steel strand bundle of the grouting pipe. For thick reinforcement, one grouting pipe is generally used to anchor one reinforcement. For tendons and steel strands, a grouting pipe must anchor several steel bars or steel strands at the same time, which are often arranged in a ring or circle, or in a rectangle. Obviously, due to the different number and arrangement of prestressed reinforcement, the form and structure of grouting pipe will also be different. According to the principle of grouting pipe and transmitting pretension,AbquikiGrouting small conduit and advance anchor rod,Abquiki50lead small conduit, it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.How much does it cost?, The small editor of the grouting pipe reminds everyone that there should be no rust, water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, and the grouting pipe should be properly kept. However, it is suggested that a small amount of lubricant (e.g. anchor pulling spirit) be applied to the tapered hole of the anchor plate by the prestressed machine, which is not only conducive to the follow-up and anchor pulling of the working clip, but also conducive to the multiple grouting of the grouting pipe; Apply lubricant on the outer surface of the tool clip and the inner and outer surfaces of the taper hole of the anchor plate before use, and regularly remove the debris on the clip surface to make the anchor flexible. However, when the clip is cracked or the tooth surface is damaged, it needs to be replaced and can not be used again. The grouting pipe has good air tightness, low gas permeability, strong sealing and no leakage.The commonly used standard for grouting pipe is the inner diameter of -mm. The wall thickness of the pipe has little effect on the sound transmission, so there is generally no need to restrict the thickness of the pipe wall. However, from the perspective of saving steel consumption, it is OK if the pipe wall can bear the lateral pressure of new concrete, not necessarily the thicker the better.Abquiki, The small editor of the grouting pipe reminds everyone that there should be no rust, water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, and the grouting pipe should be properly kept. However, when the prestressed tendon is long and the grouting pipe needs to be tensioned repeatedly, it is suggested that a small amount of lubricant (e.g. anchor pulling spirit) be applied to the tapered hole of the anchor plate by the prestressed machine which is not only conducive to the follow-up and anchor pulling of the working clip, but also conducive to the multiple grouting of the grouting pipe; Apply lubricant on the outer surface of the tool clip and the inner and outer surfaces of the taper hole of the anchor plate before use, and regularly remove the debris on the clip surface to make the anchor flexible. However, when the clip is cracked or the tooth surface is damaged, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain, easily bypass obstacles, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe?
