Pipe sheds are typically a part or the entire section of an underground engineering cross-section, installed circumferentially at certain intervals to form a steel pipe shed protection.

Caisson超前支护 is a temporary support method provided in advance to enhance the bearing capacity of the strata under special conditions, ensuring safe excavation.

Tunnel tube棚 is primarily used in tunnel engineering with soft and broken surrounding rock, where there are strict limitations on surrounding rock deformation and surface subsidence, such as in soft and sandy-gravel strata, soft rock, rock piles, and fractured zones.

(1) Steel processing manufacturers require each steel support and steel enclosure to be securely fastened to the retaining piles with wire ropes to prevent them from being disturbed during hoisting operations within the foundation pit.

(2) Steel flower pipe manufacturers typically install each support within 8-24 hours after excavation to protect the environment, reduce the deformation of retaining walls, and ensure the safety of the foundation pit.

(3) During construction, enhance monitoring. If excessive lateral pressure leads to an overlarge axial force in the steel pipe bracing, causing deflection and deformation, and it approaches the allowable limit, it is imperative to promptly take measures such as adding temporary vertical supports to prevent excessive deflection and deformation of the bracing. This ensures stable force on the steel pipe manufacturer and guarantees the safety of the foundation pit.

(4) Steel flower pipe manufacturers assign a dedicated person to inspect the support flanges of steel pipes. In case of any loosening, they promptly re-tension and secure the flanges. When inspecting the steel pipe supports, a safety harness is required due to the nature of high-altitude work.

(5) Removal of steel flower pipes must be approved by a technician and organized by a designated person.
