Steel pipe pile foundation reinforcement structure

Abstract

The present invention relates to the field of foundation technology, more specifically, it relates to a foundation reinforcement structure of steel pipe piles. A pressure plate is provided for vertical sliding, and a fixed ring is provided under the pressure plate. An elastic member is connected between the fixed ring and the pressure plate. The bottom of the pressure plate is connected with an adjustment plate through a connecting rod, and the adjustment plate has a first strip opening , the outer wall of the reinforcement pipe is provided with a receiving groove, and an anti-pull rod is hinged in the containing groove, and a second strip-shaped opening is opened on the anti-pull-out rod, and a control rod is connected between the first strip-shaped mouth and the second strip-shaped mouth. When the adjustment plate moves downward, the adjustment plate drives the anti-pull rods to swing out of the accommodation groove through the control rod, and multiple anti-pull rods form anti-pull barbs, so that a steel pipe pile foundation reinforcement structure of the present invention can improve the steel pipe pile foundation reinforcement structure. The anti-pull effect of the pipe pile, thereby improving the stability of the steel pipe pile.

Description

technical field [0001] The invention relates to the technical field of foundations, in particular to a steel pipe pile foundation reinforcement structure. Background technique [0002] In the foundation construction of the building, the steel pipe pile can be selected as the main vertical force supporting member. The construction of the steel pipe pile is convenient and fast. Compared with the construction of the bored pile, the construction period is shorter, the cost is lower, and the construction process is less , and the pollution to the environment is also low, and as the supporting member of the foundation, the steel pipe pile also has a high bearing capacity. [0003] However, after the steel pipe pile is inserted into the soil layer, the steel pipe pile is usually only fixed by the tightness of the soil on the steel pipe pile, and the friction force is used to limit the steel pipe pile to leave the soil layer upwards, the pulling effect is limited, and the stability ...

Problems solved by technology

[0003] However, after the steel pipe pile is inserted into the soil layer, the steel pipe pile is usually only fixed by the tightness of the soil on the steel pipe pile, and the friction force is used to limit the steel pipe pile to leave the soil layer upwards, the pulling effect is limited, and the stability is poor , so that the steel pipe pile foundation is not stable enough
