Abstract

The invention discloses a construction method for an anti-floating anchor. The anchor is constructed before the excavation of the foundation pit, and a reinforcement part is formed in the soil around the upper part of the anchor by high-pressure rotary spraying to ensure the excavation of the foundation pit. , the anchor does not deflect. In addition, the pre-construction of the anti-floating anchor of the present invention can be synchronized with the construction and maintenance of the pile foundation, and no additional construction period is required, which is beneficial to speed up the progress of the construction period; the anti-floating anchor of the present invention can be carried out before excavation of the foundation pit Construction, there is no problem that the soil quality at the bottom of the foundation pit is poor, and the working face after excavation is not conducive to mechanical construction; the present invention adopts the method of high-pressure rotary spraying, and carries out partial cement soil reinforcement below the designed excavation bottom surface, and the anchor rod itself and The stability of the entire foundation pit, especially the soft soil foundation pit, plays a strengthening role.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an anti-floating anchor construction method. Background technique [0002] As an anti-floating measure, the anti-floating anchor rod has the advantages of strong anti-floating ability, flexible layout, and easy construction. It is often used in anti-floating design to resist the buoyancy brought by groundwater to buildings. [0003] At present, the construction of anti-floating anchors is basically carried out at the bottom of the foundation pit, but in some cases, the soil quality at the bottom of the foundation pit after excavation is poor, and the site conditions are extremely unfavorable to the construction of the anchor, and even cannot be constructed normally. Therefore, it is necessary to carry out additional ground treatment (such as hardening, paving, etc.) on the bottom of the pit before construction, resulting in an increase in construction costs. At the sam...
