A support device and construction method for open-cut construction of comprehensive pipe gallery

Abstract

The invention belongs to the technical field of underground engineering construction, and in particular relates to a support device and a construction method for open-cut construction of a comprehensive pipe gallery, and provides a mobile support device and a construction method for open-cut construction of a comprehensive pipe gallery , which has the advantages of cost-effective open-cut method, and at the same time, it does not need to use enclosure structures such as row piles and steel sheet piles, and provides a comprehensive pipe gallery open-cut construction support device. The construction support device is mainly composed of front support The mobile support device composed of the middle support and the tail support is composed of telescopic blocks on both sides of the front support, the middle support is mainly composed of top plate, side plate and bottom plate, the middle support and the tail They are connected by hinged oil cylinders, and a propulsion device is installed between the tail support and the middle support. This device effectively solves the problem of large land occupation and serious environmental impact when using the open cut method for construction of underground comprehensive pipe galleries and pipelines. The main problem of this method is that the degree of mechanization of this method is high and the construction speed is fast.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction; in particular, it relates to a support device for open-cut construction of a comprehensive pipe gallery and a construction method thereof. Background technique [0002] Underground structures such as utility tunnels and pipelines generally have a relatively shallow burial depth. Since the rectangular section has a higher space utilization rate, the rectangular section is generally used, and the construction method is often adopted; the most economical method of the open-cut method is usually It is slope excavation, but the scope of such construction is relatively large, and noise, dust, etc. seriously affect the surrounding environment, and it is only suitable for shallow excavation depths and good geological conditions; in some environmental conditions or special geological conditions When carrying out open excavation construction under certain conditions, it is nece...

[0002] Underground structures such as utility tunnels and pipelines generally have a relatively shallow burial depth. Since the rectangular section has a higher space utilization rate, the rectangular section is generally used, and the construction method is often adopted; the most economical method of the open-cut method is usually It is slope excavation, but the scope of such construction is relatively large, and noise, dust, etc. seriously affect the surrounding environment, and it is only suitable for shallow excavation depths and good geological conditions; in some environmental conditions or special geological conditions When carrying out open excavation construction under certain conditions, it is necessary to build an enclosure structure, and if necessary, measures such as precipitation should be used to assist the construction, but this will greatly increase the construction cost, reduce the construction efficiency, and prolong the construction period, and there are also serious environmental problems. Therefore, when constructing underground structures such as comprehensive pipe corridors and pipelines, how to make full use of the economical and efficient advantages of the open-cut method while minimizing its environmental impact, reducing construction costs, and improving construction efficiency is an urgent technology to be solved topic
