Problems solved by technology

[0003] The traditional underground comprehensive pipe gallery usually adopts the integral cast-in-place construction method, and the matching waterproof system and construction technology are relatively mature. However, due to the large amount of on-site steel bar binding, formwork laying and concrete pouring in this method, the construction is usually difficult and the cycle is long. , the cost is high, so as an improvement, people have proposed a prefabricated assembly method to improve the construction process
Among them, the fully prefabricated assembly superimposed construction method of splitting the pipe gallery into basic prefabricated components of slab walls, assembled on site, and finally forming an overall structure by superimposing cast-in-place concrete has many advantages. However, due to this construction method and its waterproof The system is still in its infancy in China, the relevant norms and standards are not yet complete, and the construction experience is also insufficient, which poses a huge challenge to the actual engineering project practice

specific Embodiment

[0054] A double-compartment urban underground comprehensive pipe corridor, including gas tank and comprehensive tank, has a total width of 6.25m and a total height of 3.8m, of which the gas tank is 2.5m wide and the comprehensive tank is 3.75m wide.

[0055] The specific construction steps are as follows:

[0056] Step 1, laying concrete cushion 1-1 and cement mortar leveling layer;

[0057] Step 2. Wet lay a waterproof membrane 2-1 at the bottom of the pipe gallery on the cement mortar, and lay a corner waterproof membrane reinforcement layer 2-5 and 2-6 on both sides of the bottom at the same time, and then lay a mortar isolation layer, and finally lay Fine stone concrete protective layer 1-2;

[0058] Step 3. After the fine stone concrete protective layer 1-2 reaches a certain strength, lay a layer of fine mortar, and then immediately lay the prefabricated floor laminated concrete 4-1;

[0059] Step 4, laying prefabricated wall panels 3-2, 3-3, and supporting and fixing t...

Abstract

The invention discloses a full prefabricated superposed pipe gallery integrated waterproof structure and a construction method. A waterproof system is composed of a structural self-waterproof system and an auxiliary waterproof system. The structural self-waterproof system is composed of a prefabricated component part and a superposed concrete part, and the auxiliary waterproof system is composed of a structural external waterproof system and a deformation joint part waterproof system, wherein the prefabricated component part comprises a prefabricated bottom plate, a prefabricated wall plate and a prefabricated top plate; the superposed concrete part comprises a prefabricated bottom plate superposed concrete, a prefabricated wall plate superposed concrete and a prefabricated top plate superposed concrete; and the deformation joint part waterproof system is composed of the deformation joint part waterproof structurers of the prefabricated component bottom plate, the side wall and the topplate. The waterproof system supplements and improves the waterproof design and construction technology of China in the field, and the whole waterproof system is clear in system, simple in structure,convenient to construct, fast and efficient, easy to guarantee in quality and capable of being widely applied.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a fully prefabricated and assembled composite pipe gallery comprehensive waterproof structure and a construction method. Background technique [0002] The waterproof system plays a pivotal role in the design and construction of urban underground utility tunnels, and is an important link in the construction of utility tunnels. [0003] The traditional underground comprehensive pipe gallery usually adopts the integral cast-in-place construction method, and the matching waterproof system and construction technology are relatively mature. However, due to the large amount of on-site steel bar binding, formwork laying and concrete pouring in this method, the construction is usually difficult and the cycle is long. , The cost is high, so as an improvement, people have proposed a prefabricated assembly method to improve the construction process. Among them, the fully pr...
