Anti-floating anchor and construction method thereof

Abstract

The invention belongs to the technical field of building construction structures, in particular to an anti-floating anchor and a construction method thereof. The anti-floating anchor comprises a concrete tubular pile and an anti-pull bar bundle inserted into the concrete tubular pile. The anti-pull bar bundle comprises a plurality of anti-pull main bars and short bars arranged in the length direction of the anti-pull main bars at intervals, and the bar bodies of the short bars and the bar bodies of the anti-pull main bars are welded and fixed. An end plate is arranged at the bottom of the anti-pull bar bundle, and an end tip is arranged on the plate face of the side, away from the anti-pull bar bundle, of the end plate. Compared with a traditional anti-floating anchor, the anti-floating anchor can reach the design elevation through one time of dry operation, operation is easy, the construction speed is high, and the construction period can be remarkably shortened. According to the anti-floating anchor, hole collapse and hole shrinkage can be effectively avoided, the anti-floating anchor can be suitable for filling earth, silty clay, silty-fine sand and other hole collapse soil layers, the construction quality of the anti-floating anchor is improved, and the application range of the anti-floating anchor is widened.

Description

technical field [0001] The invention belongs to the technical field of building construction structures, in particular to an anti-floating anchor rod and a construction method thereof. Background technique [0002] When the depth of the building foundation is greater than the groundwater level, the building will be affected by the buoyancy of the groundwater and cause the phenomenon of floating. In the prior art, anti-floating anchor rods are usually used under the foundation floor to offset the vertical displacement of the building caused by the buoyancy. [0003] With the increasing development of underground space, the specifications of anti-floating anchors are gradually developing in the direction of large diameters. The traditional anti-floating anchor construction adopts wet operation method, the construction efficiency is low, and the mud generated during the operation will affect the environment. How to efficiently construct anti-floating bolts has become the focus ...
