Abstract

The invention relates to the technical field of construction engineering, and particularly discloses a pile foundation repair device. The pile foundation repair device includes a sleeve capable of sleeving a pile foundation, an anti-leakage plate is horizontally fixed to the bottom of the sleeve, a limiting port for holding the pile foundation is formed in the anti-leakage plate, a limiting plateis vertically fixed on the anti-leakage plate, a guard board I and a guard board II which are closely attached to the limiting plate are vertically arranged on the anti-leakage plate, the adjacent side edges of the guard board I and the guard board II are closely attached, the guard board I and the guard board II form a protective cavity with the pile foundation, a motion cavity is formed among the guard board I, the guard board II and the sleeve, a plurality of convex teeth facing the pile foundation are fixed to the guard board I and the guard board II, and a driving mechanism for driving the guard board I and the guard board II to reciprocate up and down is arranged in the motion cavity. According to the technical scheme in the patent, the problem that water flow can directly impact a repair layer in the prior art is solved, and then the durability of the repair layer is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a pile foundation repairing device. Background technique [0002] Concrete pile foundations are prone to cracking and damage during the pile driving project or after being impacted by the outside world; or due to insufficient protective layer, they are prone to rust and cracks. Generally, the existence of these defects has a limited impact on the bearing capacity of the pile foundation in the short term, but the long-term existence of the defects will affect the durability of reinforced concrete itself, and affect its later bearing capacity and use safety. Therefore, it is necessary to repair the defective concrete pile foundation. [0003] Due to the limitations of the characteristics of the repair and reinforcement materials, the traditional pile foundation repair and reinforcement technology is mostly carried out for the area above the level tide level. For ...
