Reserved pile hole structure suitable for static pressure anchor rod pile foundation reinforcement

Abstract

The invention provides a reserved pile hole structure suitable for static pressure anchor rod pile foundation reinforcement. An angle steel cage is arranged in a static pressure anchor rod pile reserved hole, steel wire meshes for intercepting concrete are arranged on the four walls of the angle steel cage in a surrounding mode, and angle steel and steel bars are adopted as a framework for sealing and lining the steel wire meshes to serve as a lining formwork; and the effect of intercepting concrete is achieved when the bearing platform is poured. Therefore, the pile hole achieves a mold-free and dismounting-free effect.

Description

technical field [0001] The invention relates to a reserved pile hole structure suitable for static pressure anchor pile foundation reinforcement. Background technique [0002] At present, static pressure anchor piles are widely used as an effective reinforcement method to improve the foundation bearing capacity of old structures, but most of the reinforcement projects adopt the enlarged cross-section form of the foundation cap and supplemented by anchor pile piles. During the process of hole reservation, the height of the cap is high and the reserved pile holes are irregular. If the formwork is used to reserve the pile holes during the pouring of the cap, the formwork in the wall of the pile hole is difficult to remove when the formwork is removed. , to a certain extent affect the quality of the follow-up pile sealing construction. [0003] For old building reinforcement and reconstruction projects, in order to meet the diversity of building functions, more load-bearing str...

Problems solved by technology

[0005] For most of the reinforcement projects that adopt the expanded cross-section form of the foundation cap and supplement the pile with anchor piles, in the process of reserving the anchor pile holes, the height of the cap is high, and the reserved pile holes are irregular. If the formwork is used to reserve the pile hole during the process, it will be difficult to remove the formwork inside the pile hole wall when the formwork is removed, which will affect the subsequent construction quality of the pile closure to a certain extent and the economic benefits will be low, which has become a technical issue that needs to be studied urgently
