Post-construction process of anti-floating anchor rod

Abstract

The invention discloses a post-construction process of an anti-floating anchor rod. A rough flow of construction comprises the following steps of pouring a cushion in a foundation pit; drilling an anti-floating anchor rod hole; placing the an anti-floating anchor rod in the an anti-floating anchor rod hole; pouring the an anti-floating anchor rod hole; constructing an anti-floating anchor rod holewaterproof project; bending the an anti-floating anchor rod; and binding anti-floating plate reinforcing steel bars, wherein the anti-floating plate reinforcing steel bars are in a space formed by bonding the anti-floating plate reinforcing steel bars. The process has the advantages that the process is suitable for all soil masses and rock bodies as well as basement parking garage foundations ofresidence, underground garages of commercial complexes, underground shopping malls, basement equipment room foundations, metro tunnels, metro stations, underwater structures and underwater tunnels; bottom-picking before construction of the anti-floating anchor rod is carried out to reduce immersion and damage of water and slurry caused by slurry cleaning and anti-floating anchor rod construction to a supporting layer of the foundation before construction of the anti-floating anchor rod, so that the construction period is shortened, and the replacement amount of concrete is reduced by 50%; cushion concrete pouring and forming effects are facilitated; and anti-floating anchor rod reinforcing steel bar forming is facilitated.

Description

technical field [0001] The invention relates to the field of building construction engineering foundation and foundation construction technology, in particular to a construction technology of an anti-floating anchor rod. Background technique [0002] In recent years, urban construction has become more and more crowded. In order to better solve the problem of building vertical space utilization and save the building area, the application of building underground space is becoming more and more extensive. Underground engineering encounters large underground structures with shallow groundwater levels, such as large underground basements, large underground structures, large equipment foundations, etc., and is buried deep underground. Due to the large construction area and deep foundation of such underground structures, the number of building floors is relatively increasing. In the case of the highest groundwater level in history, the self-weight of the structure is not enough to...

AI Technical Summary

Problems solved by technology

The traditional anti-floating anchor construction is to construct the anti-floating anchor first before the cushion is poured, then pour the cushion, and then bind the anti-floating plate steel bars, and pour the anti-floating plate, but if there is abundant groundwater or rock crack water , the construction of anti-floating anchor rods is very easy to cause disturbance and soaking of the foundation soil layer, and at the same time, it will form a secondary bottom picking
