Side wall of a double-sided laminated pipe gallery with concealed columns and its manufacturing method

Abstract

The invention belongs to the technical field of underground comprehensive pipe gallery, and discloses a double-sided superimposed pipe gallery side wall with hidden columns and a manufacturing method thereof. The outer prefabricated layer, the inner prefabricated layer and the hidden column are connected into a whole by pre-casting concrete and a steel skeleton , A side wall cavity is reserved between the inner precast layer and the outer precast layer, and the inner precast layer and the outer precast layer are connected into a whole through the concrete concealed columns in the side wall cavity. The present invention only needs simple flipping equipment to pour and manufacture the side wall of the double-sided laminated pipe gallery; the production environment is good, the quality of concrete maintenance is good, the thickness of the protective layer of steel bars and the distance control effect are good; the production does not require high assembly accuracy , improve the yield rate of prefabricated components and the convenience of production; the construction of anti-cracking steel mesh can be placed accurately; there is no need for major innovations in the production process of the manufacturer; and the components are not easily deformed during demoulding, transportation, and hoisting , the components are well stressed, no obvious cracks appear on the concrete surface, and the self-waterproof performance is good.

Description

technical field [0001] The invention belongs to the technical field of underground comprehensive pipe gallery, and in particular relates to a side wall of a double-sided superimposed pipe gallery with hidden columns and a manufacturing method thereof. Background technique [0002] At present, the pipelines under the urban roads are intricate and complicated. In order to solve the problems of repeated excavation of the road surface and pipeline planning and management during the use of the traditional directly buried pipelines, the urban underground comprehensive pipe gallery is an intensive and sustainable pipeline laying method. , has become a hot spot in the development of domestic underground space in recent years. With the rapid development of my country's economy and the development of cities in the direction of modernization and intelligence, the construction of urban underground comprehensive pipe corridors can not only increase the city's resistance to disasters, but...

AI Technical Summary

Problems solved by technology

[0008] (1) The material consumption of the existing fully prefabricated integrated pipe gallery and construction technology is small, but the efficiency of on-site assembly and construction is low, the hoisting machinery occupies a large space and has high requirements for the site, and the weight of all prefabricated components is heavy. The resulting transportation The cost is high, and it is impossible to pass through limited and high-demand roads in the city. The connection accuracy of prefabricated components is high. The waterproof sealing material at the assembly joint is prone to aging or damage and is difficult to replace later, resulting in the later stage of putting into use. The waterproof performance of the assembly joint severely reduced

[0009] (2) The design of the axillary corners is usually canceled in the conventional superimposed comprehensive pipe gallery, so the volume hoop ratio of the corner joints needs to be increased to ensure the reliability of the assembly, which will lead to coarse aggregate when pouring concrete from the side wall It is easy to be stuck by steel bars; more vertical supports are erected from the bottom plate, which affects the space for construction and traffic in the pipe gallery, which is not conducive to timely escape in emergencies, and there is a greater safety hazard

[0010] (3) Due to the construction technology of the all-cast-in-place integrated pipe gallery, there is a construction joint above the underarm corner, which may cause water leakage. Risk of water leakage; poor control of concrete pouring thickness, poor concrete curing conditions, difficult to strictly control the thickness and spacing of steel bar cover
