Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a phase-change concrete rectangular pipe gallery structure and construction method, which is used to solve or partially solve the problem of shield method circular section comprehensive pipe gallery under the condition of large buried depth. The weakness of low space utilization rate, and the heat generated by cables and other pipelines during the operation of the integrated pipe gallery leads to excessive temperature in the pipe gallery, a large number of ventilation machinery and equipment, and high investment costs

Embodiment 1

[0042] Such as Figure 1-Figure 4 As shown, the phase-change concrete-like rectangular pipe gallery structure includes several rectangular-like segment rings connected in sequence along the longitudinal direction (that is, the first pipe gallery section structure 1, the second section pipe gallery section structure 2, the third section Pipe gallery section structure 3, fourth section pipe gallery section structure 4), upper half partition wall 11, lower half partition wall 12, cast-in-place transverse partition 25, connecting bolts (ie longitudinal connecting bolt 13, hand hole 15, partition wall Connecting bolts 16) and seam waterproof structure. figure 1 It is a diagram of the segment block method of a rectangular pipe gallery structure. In this block method, the entire segment ring structure is composed of six segment segment blocks A1, A2, A3, A4, A5, and A6, and respectively It is defined as the segment A1 of the arc segment of the vault at the vault position, the segmen...

Embodiment 2

[0069] The assembly construction method of the phase-change concrete-like rectangular pipe gallery structure includes the following steps:

[0070] (1) According to the lithology of different formations, according to the section size of the rectangular comprehensive pipe gallery, the shield method or pipe jacking method is used for excavation, and the segments are assembled.

[0071] (2) The assembly of prefabricated segments by shield tunneling method mainly includes the following steps:

[0072] 1) Producing standard-sized dome arc segment segment 5, upper semi-arc segment segment, lower semi-arc segment segment and arch bottom segment segment 8 in the prefabricated component factory;

[0073] 2) During the advancing process of shield tunneling, each segment is hoisted, and the assembly sequence is segment 8 of the arch bottom arc segment, segment 7 of the right lower half-arc segment, and segment of the left lower half-arc segment 10. Segment 6 of the upper half-arc segmen...

Abstract

The invention relates to a phase-change concrete quasi-rectangular pipe gallery structure. The phase-change concrete quasi-rectangular pipe gallery structure comprises a plurality of quasi-rectangularsegment rings (quasi-rectangular pipe gallery sections) which are sequentially connected in the longitudinal direction, an upper half partition wall, a lower half partition wall, a cast-in-place transverse partition plate, connecting bolts and a joint waterproof structure; the quasi-rectangular segment rings are connected through longitudinal connecting bolts, and all segments in the quasi-rectangular segment rings are connected through segment circumferential connecting bolts; the middles of the quasi-rectangular segment rings are connected with the upper half partition wall and the lower half partition wall through embedded steel bars correspondingly; the upper half partition wall is connected with the lower half partition wall through partition wall connecting bolts; and the cast-in-place transverse partition plate is constructed in a cast-in-place mode and located between the partition walls and the segments. The quasi-rectangular comprehensive pipe gallery has the beneficial effects that compared with a traditional circular comprehensive pipe gallery, space structure dividing of the quasi-rectangular structure is easier, the space utilization rate is increased, laying, maintaining and repairing of various pipelines are facilitated, and the maintaining cost is reduced.

Description

technical field [0001] The invention relates to an urban comprehensive pipe gallery structure and a construction method, in particular to a rectangular phase-change concrete comprehensive pipe gallery structure and a construction method. Background technique [0002] The comprehensive pipe gallery integrates various engineering pipelines such as electric power, communication, gas, heating, water supply and drainage, etc., and is equipped with special inspection ports, hoisting ports and monitoring systems, and implements unified planning, unified design, unified construction and management. It is an important infrastructure and "lifeline" to ensure the operation of the city. As an innovative development model of co-construction and sharing, it intensively lays a variety of municipal pipelines. Compared with various municipal pipelines directly buried in the shallow space of the road, it has the advantages of beautifying the urban landscape, efficient use of underground spac...
