How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.After checking that the installed formwork is tight and seamless, clean the reserved groove, then pour concrete and vibrate it tightly. The concrete shall have at least the same strength as the structural concrete at this place, and the grouting pipe device in Hainan shall be kept clean when pouring concrete.The arrangement of the strain gauge shall be installed before the prestressing force is applied, and the bracket shall be fully cooled when the initial reading is measured; If the prestress has been applied, it must be noted in the report that the supporting axial force data reflects the change of the stress of the grouting pipe after the prestress is applied.Camagui,Calculation formula of weight per linear meter of pile foundation grouting pipe (unit: kg / M) 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,CamaguiAdvance grouting small conduit, when the clip is cracked or the tooth surface is damaged, it needs to be replaced and can not be used again.Wanju,The existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.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 etc.) and flexible reinforcement (polypropylene strip, plastic grouting pipe, warp knitted grouting pipe,CamaguiSupport advance small conduit, 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, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking.Can the stretching speed of grouting pipe be defined?

The grouting pipe at the tensioning end has good anchoring energy and self anchoring energy. Grouting pipe is generally used for tensioning. The grouting pipe at the tensioning end is composed of four parts: clip dam engineering, anchor plate, anchor base plate and spiral reinforcement. The clip is the key part of the anchoring system. It is two-piece and made of high-quality alloy steel. the particle size of cement clay paste clay is generally very small (less than .mm), the specific surface area is large, and it has colloidal chemical characteristics when encountering water. The characteristic of clay minerals is that their atoms are arranged in layers, and different arrangements form different clay minerals, the most common being kaolinite, illite and montmorillonite. 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.Inspection items,The existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.When the pipe cannot be connected due to serious blockage the following treatment principles must be followed: when it is 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?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 small editor of prestressed machines and tools will lead you to understand the main connection methods between the drive device and the wellhead: the connection between the flange of the drive head of the electric oil pump and the parallel flange is the most widely used one at present. There is a flange at the lower part of the drive head, and the size matches the flange of the Christmas tree wellhead.reform,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 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,CamaguiAdvance support of small conduit, 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, it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.CaO·SiO+nHO→CaO·SiO·（n－HO+Ca（OH）,Plastic pipe plastic pipe has a low acoustic impedance, which is used as a grouting pipe and has a large acoustic transmission rate. It can usually be used for smaller cast-in-place piles. It should be cautious when used in large-scale cast-in-place piles - because large-diameter piles need to be poured with a large amount of concrete and the hydration heat of cement is not easy to dissipate. In view of the great difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after concrete solidification, It may be separated from the concrete locally to cause air or water crevices, and add more strong reflection interfaces on the sound path, which is easy to cause misjudgment.Camagui, It is a thermoplastic material, which can be processed and formed many times, providing convenience for hot melting and electrofusion connection of pipes.The arrangement of the strain gauge shall be installed before the prestressing force is applied, and the bracket shall be fully cooled when the initial reading is measured; If the prestress has been applied, it must be noted in the report that the supporting axial force data reflects the change of the stress of the grouting pipe after the prestress is applied.It is laid in the soil, and through the bite and interlock between the grouting pipe mesh and the soil, it forms an efficient stress transmission mechanism, so that the local load can quickly and effectively spread to the large area of soil, which changes the shortcomings of the ordinary grouting pipe, such as the small peeling force of the joint (n), the easy cracking of the welding point, the difficulty of construction, and the reduction of the role of side displacement prevention. Due to the change of material ratio and construction technology, the peeling force of the welding joint is between N and N which effectively changes the above shortcomings of the traditional steel plastic grouting pipe. Because of the protruding joints at the welding position, it is called convex joint steel plastic grouting pipe, and its academic name is node reinforced steel plastic grouting pipe. The steel plastic grouting pipe is made of high-strength steel wire (or other fibers) through special treatment, polyethylene (PE) and other additives, it is a high-strength reinforced geotextile. This single belt is woven or sandwiched at a certain distance longitudinally and horizontally, and the drawn out pipe forms a spring shape and stretches automatically. 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.
