Leakage-proof construction method combining tower crane foundation and basement floor

Abstract

The invention discloses a leakage-proof construction method combining a tower crane foundation and a basement floor. The method comprises the following steps: excavating an earthwork groove and building a brick membrane along an inner wall of the earthwork groove, laying a waterproof material, distributing a foundation reinforcement cage, mounting supporting feet of a tower crane, mounting a grounding device, pouring concrete, mounting standard sections of the tower crane and the like. The leakage-proof construction method has the advantages that problems in a utilization process of the tower crane that the standard sections of a tower body are immersed in water for a long period to cause potential safety hazards including rusting and the like and the water is deposited in an installation position of the tower crane for a long period are effectively avoided, a dismounting procedure of the tower crane is simplified and the stability of connection between the earthwork groove and the basement floor is increased after the concrete is poured into the earthwork groove; and the leakage-proof construction method has very good leakage-proof effect and is suitable for being applied to a tower crane construction process of various types of mid-rise buildings and high-rise buildings.

Description

technical field [0001] The invention relates to a building construction method, more specifically, the invention mainly relates to a construction method in which a tower crane foundation and a basement floor are combined to prevent leakage. Background technique [0002] In recent years, with the rapid development of modern buildings, there are more and more high-rise buildings, super high-rise buildings, and main buildings with basements. Due to their site constraints, tower cranes (generally referred to as tower cranes) have to be installed within the range of the basement floor. Inside. The traditional construction method is to set the top of the tower foundation below the basement floor, and after the concrete pouring of the basement floor, the tower crane foundation is surrounded to form a sunken pit. Such a construction method is likely to cause long-term water accumulation in the pit during the building construction process, and when the tower crane is removed, the wa...

AI Technical Summary

Problems solved by technology

[0003] One of the purposes of the present invention is to address the above-mentioned deficiencies and provide a construction method for combining the tower crane foundation with the basement floor to prevent leakage, in order to solve the problem of narrow operating space when tower cranes are installed on the basement floor in the prior art. The process is cumbersome, and the operation of bending the steel bars after the removal of the tower crane foundation is easy to leave technical problems such as safety hazards in the later construction
