Pipe sheds are typically a portion or the entire cross-section of underground engineering, arranged circumferentially at a certain spacing to form a steel pipe shed protection.

Caisson pre-supporting is a temporary support method provided in advance to enhance the bearing capacity of the strata under special conditions for safe excavation.

Pipe shed pipe wholesale is mainly used in tunnel engineering with soft and broken rock formations that have strict restrictions on围岩 deformation and ground subsidence, such as in soft and sandy-gravel strata, soft rock, debris piles, and fractured zones.

Steel flower pipe, also known as steel anchor pipe, grouting small conduit, and advanced support pipe. Manufacturers use grouting technology to permeate cement slurry into the soil around the steel flower pipe, effectively improving the physical and mechanical properties of the soil, widely applied in temporary slope support for foundation pits. Common steel flower pipes include pipes with several grouting holes distributed on the body, and one end of the pipe gradually narrows to form a conical structure, with grouting holes also set on the surface of the conical structure.

However, during use, the grouting holes located on the conical structure inject cement mortar into the front end of the steel flower pipe. As the mortar is injected outward, the steel processing directly acts on the bottom of the steel flower pipe's insertion hole, creating a backward reactive force on the pipe, making it more prone to detaching from the soil. Particularly, steel flower pipes inserted diagonally into the soil are further affected by their own gravity, increasing the likelihood of detachment. Consequently, construction workers must set up additional supports to secure the steel flower pipes, thereby adding to their workload.
