Abstract

The present invention relates to the field of urban infrastructure construction, and aims to solve the problem of high costs caused by the construction of anti-seepage and water leakage in the deformation joints of traditional structures, the treatment of water leakage, and the long-term operation and maintenance management of ultra-long structures in underground engineering, or the leakage caused by the deformation joints of structures. If the water treatment is not timely, it will lead to the reduction of the durability and bearing capacity of the structure, which will seriously affect its stability and service life or reduce the service life and functions of various facilities in the space of the structure, and deteriorate the operating conditions of the structure. Construction method and structure of an ultra-long structural body deformation joint waterproofing and drainage structure in underground engineering, which includes the following steps: structure deformation joint construction, including base plate construction and base plate deformation joint construction, wall construction and wall deformation joint construction, roof construction and roof construction Construction of deformation joints; waterproof construction of structural body deformation joints; drainage construction of structural body deformation joints. It overcomes the problems existing in traditional structures, and can protect the groundwater environment, limit stratum settlement and simplify construction process operations.

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...

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.
