Utility tunnel convenient for spanning underground buildings and variable compartment method thereof

Abstract

The invention belongs to the technical field of municipal administration, and relates to a utility tunnel convenient for spanning underground buildings, which comprises a spanning section located below the ground surface and spanning underground buildings. The left and right sides of the spanning section are variable compartment sections, and the sides, away from the spanning sections, of the variable compartment sections are standard sections; the variable compartment sectionscomprise a first variable compartment section connected with the standard sections and a second variable compartment section connected with the spanning sections, the width of the first variable compartment section is greater than that of the standard sections, and the height is equal to that of the standard sections; the height of the second variable compartment section is less than that of the first variable compartment section, and the width is equal to that of the first variable compartment section; and the height of the spanning sections is less than that of the second variable compartment section, and the width is equal to that of the second variable compartment section. According to the utility tunnel convenient for spanningthe underground buildings, the case of collision of the elevation of the underground utility tunnel and the underground buildings is fully considered, by adjusting the cross section of the tunnel, it is ensured that the tunnel can be passed through in the way of spanning above the buildings, pipelines in the tunnel can be arranged and adjusted under the condition of meeting standard specifications, the project cost is lowered, and the investment is saved.

Description

technical field [0001] The invention belongs to the technical field of municipal administration, and relates to a comprehensive pipe gallery convenient for crossing underground buildings and a cabin changing method thereof. Background technique [0002] The comprehensive pipe gallery is a comprehensive pipeline gallery structure buried underground, so the design of the pipe gallery is bound to be affected by the underground space, especially when the underground comprehensive pipe gallery is built in the built-up area. Subway, drainage pipes and culverts, and river courses are all important factors affecting it. Therefore, the pipe corridor generally adopts the method of striding up and down to avoid underground buildings. When the overlying soil of the underground building meets the height requirements of the pipe gallery, it can be passed through by spanning. However, when the soil depth of the top of the underground building cannot meet the requirements, the lower cross...

AI Technical Summary

Problems solved by technology

[0003] In view of this, in order to solve the problem in the prior art that the covering soil depth cannot meet the conventional buried depth of the pipe gallery, the use of the lower crossing method will increase the construction difficulty and construction cost, and provide a comprehensive pipe gallery that is convenient for crossing underground buildings and Its cabin change method
