Guizhou Hengzongda Steel Structure Co., Ltd. was established on April 22, 2014, with its factory located in the largest steel market in Guizhou (Guiyang Dryang Steel Market). To meet market demand, the company also operates a branch factory in Niuxinshan, Xuiyang County, Zunyi City, Guizhou Province. The company specializes in manufacturing and processing various steel components: embedded plates, sheared plates, punched holes, bending, rolling, anchor bolts, CNC plasma cutting, anchor rods, and internal/external threading; prefabrication and installation of steel structure workshops; manufacturing and installation of various guardrails (including drum-type rotating guardrails); production and installation of complete sets of wastewater treatment equipment; and contracting various steel structure projects.

Tunnel construction pipe shed pipes can be widely used with various one-time grouting materials. After checking that the molds installed on the grouting pipes are tight and seamless, clean the pre-stored tank and compact it with vibration.

Throughout the entire concrete construction process, the installation of reinforcing steel, formwork, and pre-allocation of water and electricity are handled by professionals. Immediate injection molding of precast component interfaces and texturizing of laminated panel interfaces should be carried out.

Flexibility: Easy placement at corners, long-lasting grouting pipes for tunnel construction arches, 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, small conduits, grouting pipes, and tunnel construction arches are expected to rebound and continue. The inner core of the grouting pipe is rigid, ensuring it won't be crushed under cement pressure.

External anti-caving filter press. The filter cloth layer of the press filter only allows water and grouting fluid to pass through to prevent possible caving. It also serves as a guide during drilling to increase the closure of the hole during grouting. Key in equipment, tunnel construction pipeline, to prevent mud leakage. The outer diameter of the aforementioned cutting rotating equipment is smaller than the inner diameter of the grouting tube by mm. 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.
