The auxiliary effect of wear-resistant steel plate on steel sheet pile
In order to better avoid the fatigue and damage of the clamp position of steel sheet piles caused by the long-term high-strength action of the jaws of the oscillating hammer on the steel sheet piles, we need to weld a steel sheet 25cm wide and 2cm thick firmly in the direction that the top of each group of steel sheet piles is level with the lock ports on both sides of the steel sheet piles, and the top of the welded steel sheet is level with the steel sheet piles.
Generally, we use wear-resistant steel plate, because this steel plate can not only protect the steel sheet pile from being damaged, but also make the direction of the force of the jaw of the oscillating hammer and the direction of the force of the lock mouth, reducing the difficulty of driving the steel sheet pile.
The wear-resistant steel sheet pile may be deformed after being transported to the construction site. The production and anticorrosion of the outgoing steel sheet pile must be checked by the supervision unit before being transported to the site for storage, the qualification certificate of outgoing steel sheet pile and related raw materials, and the inspection of each outgoing steel sheet pile and wear-resistant steel sheet pile.
The transportation of steel pipe pile and steel sheet pile needs to go through multiple transfers, and the flatness deviation of the lock gate is large or the part has twists and turns or sudden changes; The two locks are not parallel and distorted. It is more important to check the standard, raw materials, flatness, section size, and pile body distortion of the pile, especially the lock position of the wear-resistant steel sheet pile. It is necessary to make a "review" of the lock gate according to the quality status of the outgoing pile, according to the quality characteristics and shortcomings of the pile, to classify the pile.
The construction of steel sheet pile system mainly includes the processing and anticorrosion of steel pipe pile, the processing and anticorrosion of wear-resistant steel sheet pile, the manufacturing of guide frame and pile rod, the driving of steel pipe pile with oscillating hammer and the diesel hammer. The manufacturing and anticorrosion of steel pipe piles are carried out in the factory; The anticorrosion of steel sheet pile is completed on site.
