Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.Four advantages of establishing a good cooperative relationship with customers: Professional production equipment and testing facilities ensure the quality of the supplied grouting pipes.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.Variable cost, The grouting pipe is a patented product. Compared with similar products in the market, it has higher tensile resistance and better sealing performance.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,New South MemphisSmall catheter, 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 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, it needs to be replaced and can not be used again.
It is required to ensure that at least one embedded reinforcement is firmly welded with the anchor ring of maolehan grouting pipe within every meter along the joint direction. The quality of XF type grouting pipe should be carefully checked. If deformation or inconsistent spacing between two steel beams is found, it should be repaired. If necessary, the steel beam spacing of maolehan grouting pipe shall also be adjusted according to the ambient temperature during installation. XF type grouting pipe device shall be slowly put into the groove, so that the center line of the joint coincides with the center line of the actual reserved joint, and the deviation shall not exceed mm. Meanwhile, the inner edge of the steel side beam shall be kept vertical. After the XF grouting pipe is in place, the top surface of its steel beam shall be adjusted according to the longitudinal, transverse slope and elevation to be ~ mm lower than the adjacent asphalt concrete pavement and shall not exceed the pavement elevation.quality,The important reason for the stability of the grouting pipe reinforced soil subgrade is to further verify the main principle of the grouting pipe reinforced soil subgrade treatment technology. It is to place various types of grouting pipe products inside,New South MemphisAdvance small conduit and pipe shed, on the surface of the soil mass or between the layers of soil mass. Relying on the tensile characteristics of the grouting pipe, the distribution of the internal stress field and displacement field of the reinforced soil mass is changed through the friction and embedment between the grouting pipe and the surrounding soil mass. When lifting and demoulding components, the concrete strength must meet the design requirements. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.New South Memphis, so as to improve the physical and mechanical properties of the bearing layer of the pile body Especially for the ballast at the bottom of the pile splitting and compaction, grouting can improve or eliminate the adverse effect of the ballast at the bottom of the pile on the end bearing capacity through the replacement, compaction and consolidation of the ballast by the slurry.II During the drilling process of the bored pile, there will be a certain gap between the pile retaining wall and the surrounding soil layer, which will lead to the decrease of the pile side friction and affect the bearing capacity of the pile When the grouting pipe is used at the pile end for grouting, fill and compact along the side of the pile under the pressure, so as to complete the replacement of the mud skin around the pile and the filling of the gap, such as greatly improving the pile side friction resistanceHow heavy is a grouting pipe?
