Tunnel construction pipe arches can be widely used with various single-use grouting materials. After inspecting that the molds installed on the grouting pipes are tight and seamless, clean the pre-stored tank thoroughly and compactly.

Throughout the entire concrete engineering process, the installation of steel bars, formwork, and the pre-allocation and pre-b埋 of water and electricity are handled by professionals. Immediate injection molding of precast component contact surfaces and the roughening of lamination panel contact surfaces should be conducted.

Flexibility: Easy placement at corners, long-lasting grouting pipes for tunnel construction, deep excavation with hollow grouting bolts, and the industry value and new trends of steel flower pipe clamps for grouting. Various products such as pipe materials, advanced small conduits, grouting pipe manufacturers, and tunnel construction arch pipes are expected to rebound and continue. The inner core of the grouting pipe is rigid, ensuring it will not be crushed under cement pressure.

Outside frame, no reverse pressure filter. The filter cloth layer of the pressure filter only allows water and grouting fluid to pass through to prevent possible collapse. It also serves as a guide during drilling to enhance closure at the hole mouth during grouting. Key in equipment for tunnel construction pipelines to prevent slurry leakage. The outer diameter of the above cutting rotating equipment is mm smaller than the inner diameter of the grouting pipe. Inspection pipes can be welded with electric welding or tied to the inner side of the building reinforcement, and the inspection pipes should be parallel to each other.
