Formwork-free concrete single-cabin pipe gallery or multi-cabin pipe gallery and construction method thereof

Abstract

The invention relates to a formwork-free concrete single-cabin pipe gallery or multi-cabin pipe gallery and a construction method thereof. The pipe gallery comprises a top plate, a bottom plate and awall body which are connected with one another, wherein the wall body comprises an outer wall body and further comprises or does not comprise a partition wall body; the wall body adopts a cast-in-place reinforced concrete structure and is mainly composed of wall body fixing formworks positioned on the two sides of the wall body and a wall body concrete layer poured between the wall body fixing formworks on the two sides; the wall body fixing formworks adopt steel bar truss fixing formworks; each steel bar truss fixing formwork comprises a panel, a steel bar net and a steel bar truss, wherein the steel bar net and the steel bar truss are positioned on one side of the panel; and the top plate and the bottom plate are preferably of cast-in-place concrete structures. The construction method comprises the steps of bottom plate construction, wall body construction, top plate construction and necessary concrete oxidation. According to the formwork-free concrete single-cabin pipe gallery or multi-cabin pipe gallery and the construction method thereof, the workload and the labor intensity of pipe gallery construction can be reduced, the influence degree of human factors on the building quality is reduced, the construction cost is reduced, and the adverse effects on the environment and the society in the pipe gallery construction process are reduced.

[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
