A formwork-free concrete single-cabin pipe gallery or multi-cabin pipe gallery and its construction method

Abstract

The invention relates to a formwork-free concrete single-chamber pipe gallery or a multi-chamber pipe gallery and a construction method thereof. The pipe gallery includes a top plate, a bottom plate and a wall that are connected to each other. The wall includes an outer wall, and also includes or does not include a partition wall. The walls are all cast-in-place reinforced concrete structures. The wall solid formwork on both sides of the wall and the wall concrete layer poured between the wall solid formwork on both sides are constituted, and the wall solid formwork adopts a reinforced truss fixed formwork, and the reinforced truss fixed formwork includes a panel and a The steel mesh and steel truss on one side of the panel, and the top and bottom plates are preferably cast-in-place concrete structures. The construction method includes floor construction, wall construction, roof construction and necessary concrete oxidation. The invention is beneficial to reduce the workload and labor intensity of pipe gallery construction, reduce the degree of influence of human factors on building quality, reduce construction costs, and reduce the adverse impact on the environment and society during the construction of the pipe gallery.

Description

technical field [0001] The invention relates to a formwork-free concrete single-chamber pipe gallery or a multi-chamber pipe gallery and a construction method of the same, belonging to the technical field of construction. Background technique [0002] The underground comprehensive pipe gallery is a comprehensive corridor of urban underground pipelines, in the shape of a tunnel. According to the needs of use, it can be designed as a single-cabin pipe gallery or as a multi-cabin pipe gallery for urban electricity, communication, gas, heating, water supply and drainage, etc. All kinds of engineering pipelines can be set in the pipe gallery to facilitate management and maintenance. Due to the strict requirements of pressure bearing and anti-seepage, the construction of underground pipe gallery can be roughly divided into two technical routes.

Problems solved by technology

[0002] The underground comprehensive pipe gallery is a comprehensive corridor of urban underground pipelines. It is tunnel-shaped. According to the needs of use, it can be designed as a single-cabin pipe gallery or as a multi-cabin pipe gallery. Urban electricity, communications, gas, heating, water supply and drainage, etc. All kinds of engineering pipelines can be installed in the pipe gallery to facilitate management and maintenance. Due to the strict requirements on pressure bearing and seepage prevention, the current construction of underground pipe gallery can be roughly divided into two technical routes. One is to use cast-in-place reinforced concrete structure, this technical route requires a large amount of on-site operations, complex construction, high labor intensity, a large work site needs to be excavated, and a special formwork needs to be designed. Problems are difficult to detect and repair. Today, when suitable labor resources are in short supply and labor costs are increasing, these problems lead to high construction costs; the second is to use prefabricated components, transport the prefabricated components to the site for assembly, and then perform butt joint repair and sealing of the joints. Because the component prefabrication site is often far away from the site, the transportation volume is large, and special transportation vehicles and transportation management methods are often required, the transportation cost is high, and the site needs to be equipped with large hoisting equipment, which also leads to an increase in construction costs, especially for prefabrication. The component assembly structure is prone to leakage and other phenomena, and the requirements for anti-seepage treatment are strict
