Multilayer urban underground comprehensive pipe gallery

Abstract

The invention discloses a multi-layer urban underground comprehensive pipe gallery, which comprises: a dangerous gas structure layer arranged on the top floor of the comprehensive pipe gallery for carrying natural gas pipelines; a power and telecommunication system structure layer arranged under the dangerous gas structure layer , used to carry power and communication equipment and cable devices; and the sewage structure layer, which is set at the bottom of the comprehensive pipe gallery, and used for sewage drainage in the comprehensive pipe gallery; among them, the dangerous gas structure layer, the power telecommunication system structure layer and the sewage discharge structure layer They are isolated from each other to form independent compartments with functional partitions. The multi-layer urban underground comprehensive pipe gallery of the present invention significantly improves the comprehensive utilization efficiency of urban land, improves the safety of the design of the pipe gallery, reduces the construction cost of the urban comprehensive pipe gallery, and has positive effects on the construction of the urban comprehensive pipe gallery. Guiding significance.

Description

technical field [0001] The invention relates to an underground comprehensive pipe gallery, in particular to a multi-layer urban underground comprehensive pipe gallery. Background technique [0002] The Guiding Opinions of the General Office of the State Council on Promoting the Construction of Urban Underground Comprehensive Pipe Gallery (Guobanfa [2015] No. 61) was announced on August 10, 2015. The goal of the guidance is to build a number of internationally advanced underground integrated pipeline corridors and put them into operation by 2020, the problem of "road zippers" caused by repeated excavation of the ground has been significantly improved, and the safety level of pipelines and disaster prevention and resistance capabilities have been significantly improved. , Gradually eliminate the spider web overhead lines on the main streets, and the urban ground landscape has improved significantly. [0003] The urban underground comprehensive pipe corridor project refers to ...

AI Technical Summary

Problems solved by technology

[0005] However, due to historical reasons, most of the comprehensive pipe corridors in China are planned and constructed in new urban areas or development zones, and it is difficult to enter the old urban areas for construction. The main difficulties they face include: the section of the underground comprehensive pipe corridor is relatively wide , but the urban roads or passages are too narrow to meet the construction requirements of the utility tunnel; open-cut excavation is required during the construction of the underground comprehensive utility corridor, and the cross-section is too wide to affect urban traffic and people's lives; land resources in some cities are scarce and cannot provide for the underground comprehensive utility corridor More land resources; underground and above-ground transportation facilities are complex, and the construction of underground comprehensive utility corridors may affect the overall urban transportation function and the safety of transportation facilities, etc.
