　　Seamless steel pipe small pipe punching machine, precise and advanced small pipe forming machine manufacturer

　　Punching machines have been widely used in tunnel construction. The punching machine can set 200 holes on one pipe, and the machine is matched with a servo motor. The hole spacing error is within ± 0.3mm, and the punching speed is fast, which greatly improves the manual cutting speed compared to before. The circular holes are also relatively neat and beautiful.

　　Supporting principle editor: Advanced small conduit is a very effective auxiliary construction for excavation work face. In the construction of weak and fractured rock layers, advanced small conduits play a reinforcing role in loose rock layers. After grouting, the properties of loose and weak surrounding rock are enhanced, which is conducive to the stability of the surrounding rock after excavation and during the initial support period, so as not to cause instability and collapse of the surrounding rock. Advanced small pipe grouting is suitable for weak surrounding rock in arch areas, loose, non cohesive soil layers, sand layers with poor self stabilization ability, and gravel (pebble) layer level fractured rock layers. By injecting grout through advanced small conduits, the condition and properties of the surrounding rock can be changed. After injecting grout into weak, loose formations or fractured rock fractures containing water, it can tightly fix with them. The slurry is used for filling, splitting, etc., to replace the water and air between soil particles and rock cracks, occupying their positions. After a certain period of time, it solidifies and binds the original loose soil particles or cracks into a whole, forming a new structure with high strength and good waterproof performance, which greatly reduces the loose and broken state of the surrounding rock. The seamless steel pipe small pipe punching machine is a precision advanced small pipe forming machine manufacturer.

　　Before grouting, check whether the pipe opening meets the sealing standard to prevent leakage of grout. Grouting is carried out using a grouting machine, with a grouting pressure of~Mpa. Generally, the end standard is based on the grouting volume of a single pipe reaching the construction drawing. When the grouting pressure reaches the final pressure for no less than minutes and the grouting volume still cannot reach the final grouting volume, the grouting can also be ended. After the grouting is completed, seal the pipe mouth to prevent the grout from flowing back out of the pipe. The labor organization for the advanced support construction process of the nine homework organizations is shown in the table below. Job types include drilling and blasting workers, steel reinforcement workers, electric welders, grouting workers, electricians, transportation drivers, and team leaders. The total anchor spraying support construction is determined based on the design requirements and the level and rock properties of the surrounding rock on site. The various material consumption is determined according to the design requirements, the seamless steel pipe small pipe punching machine, and the precise advanced small pipe forming machine manufacturer.
