Double-sided superposed pipe gallery side wall with embedded columns and manufacturing method thereof

Abstract

The invention belongs to the technical field of underground comprehensive pipe galleries, and discloses a double-sided superposed pipe gallery side wall with embedded columns and a manufacturing method thereof. An outer prefabricated layer, an inner prefabricated layer and the embedded columns are connected with a steel bar framework into a whole through pre-cast concrete; a side wall cavity is reserved between the inner prefabricated layer and the outer prefabricated layer; and the inner prefabricated layer and the outer prefabricated layer are connected into a whole through the concrete embedded columns in the side wall cavity. According to the double-sided superposed pipe gallery side wall with the embedded columns and the manufacturing method thereof, only simple turnover equipment isneeded for pouring and manufacturing the double-sided superposed pipe gallery side wall during pouring and manufacturing; the manufacturing environment is good, the concrete curing quality is good, and the control effect of the thickness and the distance of a steel bar protection layer is good; high splicing precision is not needed during production and manufacturing, and the yield of prefabricated parts and the convenience during production are improved; an anti-cracking steel bar net can be accurately placed; the production process of a manufacturer does not need to be greatly innovated; andthe parts are not prone to deformation in the demolding, transporting and hoisting processes, the stress of the parts is good, obvious cracks do not occur on the surface of the concrete, and the self-waterproof performance is good.

Description

technical field [0001] The invention belongs to the technical field of underground comprehensive pipe gallery, in particular to a side wall of double-sided superimposed pipe gallery with concealed columns and a manufacturing method thereof. Background technique [0002] At present, the pipelines under the urban roads are intricate. In order to solve the problems of repeated excavation of the road surface and pipeline planning and management during the use of traditional direct buried pipelines, the urban underground comprehensive pipeline corridor 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, cities are developing in the direction of modernization and intelligence. The construction of urban underground comprehensive utility corridors can not only increase the city's resistance to disasters, but also effectively strengthen the...

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
