Attention should be paid to quality and inspection in the construction of steel sheet pile

As a new type of building materials, steel sheet pile plays a great role in the life around us. For example, in the construction of bridge cofferdam; large pipeline laying temporary ditches for excavation of retaining, retaining and retaining walls; wharf, unloading yard, retaining wall, retaining wall, embankment revetment and so on, play an important role in engineering. For the steel sheet pile construction, such projects, the premise work is necessary to be near perfect, because it is related to the quality of the project. Especially the problem of raw materials.

The inspection of steel sheet piles is divided into the following steps:

1. The quality of steel sheet piles must conform to the design requirements and the technical standards of the factory. Repeated use of steel sheet piles should comply with the requirements of the following table:

2. The elevation of the steel sheet pile and the treatment of the joint joint of the pile must be in accordance with the requirements of the design and the regulations of the construction.

3. The installation of the steel sheet pile supporting structure must conform to the design requirements, which is in accordance with the design calculation conditions of the foundation pit supporting structure.

4. The setting, verticality and elevation of the steel sheet pile support must meet the design requirements. The deviation of pile position, axis and vertical axis should not exceed 50mm, the perpendicularity deviation should not be greater than 0.5%, the elevation deviation is not greater than 30mm, and the pz 27 sheet pile support must be tightly attached to the soil wall.
