Use wear-resistant steel plate to reduce the difficulty of driving steel sheet pile
In order to better avoid the joint position of steel sheet pile caused by the long-term high strength action of the jaw of the oscillating hammer on the steel sheet pile, the position of steel sheet pile clamp is tired and damaged. In the direction that the top of each group of steel sheet piles is level with the locking openings on both sides of the steel sheet piles, a steel sheet 25cm wide and 2cm thick should be welded firmly, and the top of the welded steel sheet should be level with the steel sheet piles.
The wear-resistant steel plate is introduced here, which 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 be the same, reducing the difficulty of inserting the steel sheet pile.
The wear-resistant steel sheet pile may be deformed after being transported to the construction site, and the production and anti-corrosion of the steel pipe pile must be checked by the supervision unit before being transported to the site for storage. Steel sheet pile qualification certificate and related raw materials. Check and inspect each steel pipe pile and wear-resistant steel sheet pile.
Steel pipe pile, steel sheet pile transportation journey is long and after many transshipments. It mainly indicates that the flatness deviation of the lock is large or 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.
