Description

Technical Field

[0001] This utility model relates to the field of anchor static pressure pile technology, specifically to an anchor static pressure pile. Background Technology

[0002] Anchored static pressure piles are a commonly used foundation reinforcement technology. The core of this technology is to combine anchors with static pressure piles: first, holes are drilled in the building foundation, anchors are inserted to fix the reaction frame, and then the weight of the building itself is used as the reaction force. Precast piles (or steel piles) are pressed into the soil section by section by jacks. Finally, the piles are connected to the original foundation, thereby improving the bearing capacity of the foundation and controlling the settlement of the building. For example, utility model patent CN207484479U discloses an anchor static pressure pile driver, including a pile driving frame fixed to the ground. The pile driving frame includes two columns perpendicular to the ground and a crossbeam connecting the tops of the two columns. The pile driving frame is equipped with hydraulic jacks, and the top of the hydraulic jacks is connected to a bearing beam that slides vertically on the pile driving frame. Both ends of the bearing beam are connected to sleeves fitted outside the columns. The pile driving frame is equipped with a locking mechanism to fix the position of the bearing beam. The bearing beam slides on the columns through the sleeves and is kept vertically connected to the pile driving frame, so that the hydraulic jacks always apply force to the precast pile along the axis of the precast pile, thereby avoiding uneven force on the precast pile and causing it to tilt. The locking mechanism fixes the bearing beam at different heights, so that the height of the hydraulic jacks can be adjusted in time according to the height of the precast pile exposed above the ground, which facilitates better pressure application to the precast pile.

[0003] However, the aforementioned device lacks a limiting mechanism, preventing the anchor rods from being properly restrained during use, which makes them prone to loosening. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor static pressure pile, which solves the problem that when the device is in use, the anchor rod is not easily limited due to the lack of a limiting mechanism, which makes it easy for the anchor rod on the device to loosen.
