Underground engineering ultra-long structure body deformation joint anti-drainage structure construction method and structure

Abstract

The invention relates to the field of urban infrastructure construction, and aims to solve the technical problems that the cost is high due to the seepage-proofing and water leakage construction of atraditional structure body deformation joint and the long-term operation and maintenance management of the underground engineering ultra-long structure body, or the durability and the bearing capacityof the structure body are reduced due to the fact that the seepage and water leakage treatment of the structure body deformation joint is not in time, the stability and the service life are seriouslyinfluenced, or the service life and the functions of various facilities in the structural body space are reduced, and the operating conditions of the structural body are deteriorated. The invention provides an underground engineering ultra-long structure body deformation joint anti-drainage structure construction method and structure. The method comprises the following steps of structure body deformation joint construction comprising bottom plate construction, bottom plate deformation joint construction, wall construction and wall deformation joint construction, roof construction and roof plate deformation joint construction; structural body deformation joint waterproof construction; structural body deformation joint drainage construction. The problems of the traditional structure body are solved, the underground water environment can be protected, stratum sedimentation can be limited, and the construction processes can be simplified.

Description

technical field [0001] The invention relates to the field of urban infrastructure construction, in particular to a construction method and structure of a deformation joint waterproofing and drainage structure of an ultra-long structure of an underground project. Background technique [0002] Buildings are often deformed under the action of external factors, resulting in cracking or even damage to the concrete of the structure. Deformation joints are structural joints reserved for this situation. For ultra-long structures in underground engineering (such as: underground comprehensive pipe gallery, water diversion culvert, box culvert), generally no more than 20 meters, a 30mm wide deformation joint is set to prevent The subsidence of the foundation is uneven, causing the concrete of the structure to crack. [0003] The ultra-long structure of underground engineering is buried under the ground surface, and the deformation joint is the weakest part of its anti-seepage and wate...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims to provide a construction method for the waterproof and drainage structure of the deformation joints of the super-long structure of the underground engineering, so as to solve the problems caused by the anti-leakage construction of the deformation joints of the traditional structure, the treatment of the leakage water and the long-term operation and maintenance management of the super-long structure of the underground engineering. High costs or untimely treatment of water leakage from deformation joints of the structure will lead to a reduction in the durability and bearing capacity of the structure, seriously affecting its stability and service life or reducing the service life and functions of various facilities in the structure space.
