Construction method of basement gravel filling grouting anti-floating anchor rod

Abstract

The invention discloses a construction method of a basement gravel filling grouting anti-floating anchor rod. A jumbolter is used for pipe-following drilling, impact holing is conducted, the gravel filling grouting anti-floating anchor rod is arranged for connecting building or structure bases with overlaying bedrocks into an integral and resisting the buoyancy of underground water together with an upper part structure. Compared with a traditional anti-floating anchor rod construction technology, the quality of a gravel filling grouting body is more stable, construction is faster, and pipe blocking is not caused during grouting so that the quality of the grouting body is not affected; the construction noise is low, working, studying, and relaxing of people are generally unaffected, the surrounding environment is not affected in a bad way. According to the construction method of the basement gravel filling grouting anti-floating anchor rod, the construction device is simple, operation is simple, the construction period is short, the labor intensity is low, the hole forming speed is fast, and the qualified rate of the quality of an anchor rod is high; cement is saved, the cost is lowered, the quality of the anchor rod can be effectively controlled, and the performance risk is reduced.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a construction method for gravel-filling and grouting anti-floating bolts in a basement. Background technique [0002] In today's basement floor anti-floating treatment project, the anti-floating anchor project is widely used. [0003] Utilize the bolter drilling rig to drill with the pipe, impact to form a hole, set the anti-floating anchor bolt for gravel filling to connect the base of the building or structure with the underlying bedrock, and resist the buoyancy of the groundwater together with the upper structure. [0004] The gravel-filling grouting method will not cause pipe plugging, and the gravel-filling grouting body is more uniform and dense, which can better ensure the quality of the bolt; the construction process is simple, the construction speed is fast, and the construction cost is low, which is conducive to project cost control; It affects the progress of ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a construction method for anti-floating anchor bolts with gravel filling and grouting in the basement, which solves the problems that the traditional technology is easy to block the pipe, the grouting body is not uniform and compact, and the quality of the anchor bolts is poor. , the process principle is simple, the construction process and operation points are easy to understand, the equipment is convenient to operate, the anchor bolt construction is safe, the quality is reliable, and the construction quality meets the requirements of the design and relevant specifications; it is suitable for the anti-floating treatment project of the basement floor of buildings and structures
