What auxiliary role does the weather-resistant steel plate have on the steel sheet pile?

In order to better avoid the fatigue damage of steel sheet pile claw caused by the long-term high strength action of vibration hammer claw in the process of steel sheet pile inserting, it is necessary to set the direction of the top of each group of steel sheet piles parallel to the locks on both sides of the steel sheet pile. Solidly welded 25cm wide 2cm thick steel plate. The top of the welded steel plate is flush with the steel sheet pile.

Under normal circumstances, we use 400 wear-resistant steel plates, because this steel plate can not only protect the steel sheet pile from damage, but also reduce the difficulty of inserting the steel sheet pile by the force direction of the pendulum claw and the force direction of the locking joint.

The weather-resistant steel sheet pile may produce large deformation after being transported to the construction site. The production and anti-corrosion of steel pipe piles must be inspected by the supervision unit before they can be transported to the site for storage, and the certification of steel sheet piles and related raw materials should be provided. Each batch of steel pipe piles and wear-resistant steel sheet piles should be inspected.

The transportation of steel pipe pile and steel sheet pile must go through repeated transfer, and the straightness deviation of the lock gate is large or local distortion or sudden change; The locks on both sides are not parallel and distorted. On-site inspection of pile standard, raw materials, flatness, section size, pile deformation, especially the locking part of wear-resistant steel sheet pile is more important. The lock should be "inspected" according to the quality condition of the pile on site, and the pile should be classified according to the quality characteristics and defects of the pile.

The construction of steel sheet pile system mainly includes the processing and anticorrosion of steel pipe pile, the processing and anticorrosion of weather-resistant steel sheet pile, the production of guide frame and pile feed rod, the insertion of vibration hammer into steel pipe pile and the diesel hammer feed pile. The production, processing and anti-corrosion of steel pipe piles are carried out in the factory; The processing and anticorrosion of steel sheet pile are completed on site.
