Crawler foundation Pile Driver experience

Due to the deviation in piling and the limitation of construction conditions, the actual length of the curtain cannot be an integer multiple. Standard width of sheet piles, sheet pile curtains are closed and closed at the end. Difficult, how to adjust this situation, steel sheet piles generally use special-shaped steel sheet piles or standard piles to adjust the axis of the curtain to close. We have to say that in the process of removing steel sheet piles, the first thing to do is to overcome the resistance of the piles and reduce the cohesion of the surrounding soil. And remove the piles with additional lifting action, after removing the sheet piles. The remaining pile holes should be filled in time to avoid greater danger, the material used is medium sand, for the storage of steel sheet piles. It is the storage location, as far as the site is concerned, it is necessary to choose a place where paralleling will not occur due to the high pressure, and a relatively flat and strong part should be used to avoid the steel sheet pile, which is deformed by its own weight.

(1) The construction site shall have "three connections and one leveling". According to site conditions, make conditional ground concrete cushion. Drainage ditches, water collecting wells, etc. should be set up around, and the accumulated water in the pile holes should be deposited.

(2) Release the line according to the drawing, release the center line of the pile position and the diameter of the pile, carefully review the technology, and go through the visa formalities of the relevant departments before excavating the earthwork of the pile body.

(3) Before digging the piles, four pile core control points should be drawn from the center of the pile to the periphery of the pile and calibrated with firm wooden piles.

⑷Before construction, the technical person in charge of the construction site and the construction workers should inspect the construction hole by hole, and conduct technical safety disclosure and safety education according to the level, so that safety, technical management, organization and measures should be implemented.
