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.There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.Cambridge, The fast cutting device in the hole of the underground grouting pipe according to claim , wherein the cutting rotating device rotates the cutting blade and pulley through a socket wrench to cut the casing wall, and the cutting rotating device is a wrench or a tooth wrench. The grouting pipe is padded with the front lip of the horseshoe,CambridgeGrouting flower tube,In limestone area, the punching is not good, and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work, and even can not be detected. Therefore, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement, flushing and pigging with high-pressure water, and using a drill with a small drill to clean the hole.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 main elastic element of the grouting pipe is the stainless steel grouting pipe, which compensates the axial, lateral and angular direction of the pipe by the expansion and bending of the grouting pipe.

The grouting pipe is used to pad the bottom of the horseshoe, change the cooperation specification of the mold, and adjust the cooperation space between the lower tire and the horseshoe.● advantages: Simple installation complete set; The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (it is recommended that the longest grouting outlet length should not exceed m); No special installation equipment is required; Grouting time can be arbitrarily selected; When grouting is carried out internally under proper pressure, the grouting pipe fluid can keep filling the whole pipe evenly; The system allows grouting under relatively low pressure; The grouting pressure is .-.mpa.Appropriate measures shall be taken to prevent surface water, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, The grouting pipe is used to pad the bottom of the horseshoe, change the cooperation specification of the mold, and adjust the cooperation space between the lower tire and the horseshoe. It has good flexibility. The pipes can be coiled when they are produced, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain, easily bypass obstacles, and is convenient for construction.Can the piston rod of the grouting pipe be protected to avoid being bruised and accelerating leakage?

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, 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.High value,CambridgeAdvance small conduit in tunnel construction,Welding is strictly prohibited during use,CambridgeLeading small conduit manufacturer, 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 but the excessive strength will be harmful to the quality of the upsetting head. Therefore, you should explain it in detail to the manufacturer in the order.Ceramic process : make and process gypsum molds according to the requirements of a certain place. The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, which is caused by the Chengdu grouting pipe manufacturer&#;s failure to smooth (flatten) the grouting pipe along the horseshoe surface.Cambridge, It is safe and does not need to be welded on site. 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, that is, there is an active gap. Therefore, the Chengdu grouting pipe manufacturer kneads the pipe wall to form an 'eight' shaped wrinkle.?
