Problems solved by technology

[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

Embodiment 1

[0031] Embodiment one: if Figure 1~4 As shown, a support device for open-cut construction of a comprehensive pipe gallery is provided, which is mainly a mobile support device composed of a front support 6, a middle support 7 and a tail support 8. The front support of the device is composed of It is composed of telescopic blocks 9 arranged on both sides of the front support, and the middle support is arranged at the rear end of the front support, which is mainly composed of a top plate 10, a side plate 11 and a bottom plate 12. The support is mainly composed of tail side plates 13, the middle support and the tail are connected by a hinged oil cylinder 14, and a propulsion device 15 is also arranged between the tail support and the middle support. The front end of the propulsion device and the middle support The block is connected, and the rear end is connected with the tail support block.

[0032] A partition 16 is arranged inside the middle support.

[0033] A tail bottom p...

Embodiment 2

[0044] Example 2: Take the construction of a single-cabin comprehensive pipe gallery with a section size of 4m wide and 3m high as an example. The pipe gallery is covered with 2m of soil and has a total length of 800m. It is planned to be built under the central green belt of the urban road. Slope excavation, and the use of the traditional enclosure structure will increase the project cost, the construction of the present invention can complete the construction task economically and quickly, in the specific application, first construct the starting work well and the receiving work well of the mobile support device; According to the site and design conditions, the underground comprehensive pipe gallery to be constructed is divided into two sections, each section is 400m in length, and the shield launching shaft and receiving shaft are set at both ends of each section. The two sections connected end to end will be constructed later. The first section can use the receiving well of...

Abstract

The invention belongs to the technical field of underground project construction, particularly relates to a supporting and retaining device for open excavation construction of a comprehensive pipe gallery and a construction method thereof, and discloses the movable supporting and retaining device for open excavation construction of the comprehensive pipe gallery and the construction method thereof. The supporting and retaining device for open excavation construction of the comprehensive pipe gallery has the advantages of economization and high efficiency of the open excavation method and does not have to utilize building envelopes such as pile rows and steel sheet piles. The movable supporting and retaining device for construction mainly comprises a front supporting and retaining part, a middle supporting and retaining part and a tail supporting and retaining part, the front supporting and retaining part is composed of expansion blocks on the two sides of the front supporting and retaining part, the middle supporting and retaining part mainly comprises a top plate, side plates and a bottom plate and is connected to the tail supporting and retaining part through hinging oil cylinders, and propelling devices are arranged between the tail supporting and retaining part and the middle supporting and retaining part. According to the supporting and retaining device, the main problems that the construction occupation range is wide and the environmental influence is serious in the construction process of the underground comprehensive pipe gallery and pipelines through the open excavation method are effectively solved. The construction method has the advantages that the mechanization degree is high and the construction speed is high.
