Description

Technical Field

[0001] This utility model belongs to the field of static pressure pipe pile construction technology, and specifically relates to a static pressure pipe pile verticality control device. Background Technology

[0002] During the process of using a static pressure machine for pile driving, after the static pressure machine's pile gripper releases the pipe pile, the pipe pile will fall freely. Due to the lack of external force control, it is highly likely that it will be in a skewed state in the hole, resulting in unqualified verticality and affecting the construction quality.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN220080015U discloses a pile planting device for maintaining the verticality of static pressure pipe piles. The device uses a protruding shoulder to position the guide cylinder, preventing it from sinking excessively into the foundation pit and ensuring its vertical position. A hook-and-loop connection facilitates lifting of the entire structure formed by the guide cylinder and the protruding shoulder. When the pipe pile is introduced into the guide cylinder and then placed into the foundation hole, the guide cylinder provides guidance, effectively ensuring the verticality of the pipe pile as it falls into the hole, thus improving construction quality. However, during construction, it is difficult to ensure that the protruding shoulder is placed horizontally on the ground. If the protruding shoulder is tilted, it will affect the guide cylinder, thus affecting the verticality of the pipe pile. Furthermore, it is difficult to adjust the verticality of the guide cylinder.
