Description

Technical Field

[0002] The pile gripper of a static pressure pile driver refers to an auxiliary device specially designed for use in static pressure pile drivers in water transport projects. Its main function is to firmly hold the pile body and ensure that the pile body can be stably and accurately implanted into the predetermined position during the static pressure pile driving process. The pile gripper, through its unique structural design, can adapt to piles of different diameters and lengths, providing sufficient clamping force and stability to meet the complex and changeable construction needs in water transport projects. In addition, the pile gripper also has the characteristics of simple structure, easy operation and high durability. It is an indispensable and important part of the static pressure pile driver in water transport projects.

[0003] The pile gripper of a traditional static pressure pile driver can usually only perform a single clamping operation on U-shaped steel sheet piles, and the clamping stability is poor. In complex construction environments, it is difficult to meet diverse construction needs. In addition, the pile gripper can usually only clamp the two sides of the steel sheet pile, which cannot ensure that the steel sheet pile is not deformed and cannot form a surround-wrapped clamping.
