The steel sheet pile is a steel structure with a linkage device at the edges, and the linkage device can be freely combined to form a continuous and compact retaining wall or a retaining wall. The application of steel sheet piles extends throughout the construction industry, and the construction specifications of steel sheet pile cofferdams are becoming increasingly important.
The steel sheet pile cofferdam construction specifications can help the majority of construction users to reduce the occurrence of problems during the construction process. The steel sheet piles have high strength and strong waterproof performance. Once there is something wrong in the construction process, it will take time and effort to remove them again.
Regarding the construction specifications of steel sheet pile cofferdams, a set of construction specifications summarized by steel sheet pile manufacturers: the editor has described in detail several important matters needing attention.
Before construction of steel sheet pile cofferdam, make preparations:
Level the site and fill the construction platform: Use the excavator and loader to level the site, fill the 1250px brick concrete construction platform, and compact it. Drain ditches around the platform to prevent flooding of the construction platform. In order to prevent the overturning of the pile driving hammer, a 50 px rear steel plate is laid under the pile driving track.
Inspection of vibrating hammer: Vibrating hammer is the key equipment for pulling out steel sheet piles, and special inspection must be performed before pulling out to ensure that the line is unblocked and functions normally. Whether the fuel tank is full, the oil pipe of the vibrating hammer is intact, and the teeth of the splint must not be too worn.
Handling of steel sheet piles and the setting of pile driving guidance tools: inspection and correction of steel sheet pile bodies, the size of the steel sheet pile cofferdam of the guide device is enlarged by 50 cm around the periphery of the platform. The guides are also rectangular. Eight positioning piles are driven on the inner side of the cofferdam, the ox legs are welded, and then the guide frame is installed.
The cofferdam structure needs to support the inner side of the cofferdam, which requires the selection of steel pipes, I-beams or H-beams for support according to the size and depth of the cofferdam. Large cofferdams need to be designed for the overall structure of the cofferdam. Usually, finite element analysis software is used to design the cofferdam to ensure the stability of the overall structure of the cofferdam.
Minor problems regarding the construction specifications of steel sheet pile cofferdams will be discovered in the course of construction. If you encounter any problems, please contact us and we will answer your questions.
