Utility tunnel gas pipeline confidence coefficient quantitative evaluation method and evaluation system

Abstract

A utility tunnel gas pipeline confidence coefficient quantitative evaluation method comprises the following steps: 1, setting a measuring point station in each fireproof subarea in a tunnel gas chamber; 2, setting a measuring point station at each node of the gas pipeline in the tunnel; 3, realizing wireless communication network transmission between each measuring point station in the tunnel gaschamber and each measuring point station on the tunnel gas pipeline and a tunnel monitoring center server, and sending the data information gathered by each measuring point station to the tunnel monitoring center server; 4, enabling the tunnel monitoring center server to determine a danger level of the gas pipeline in the tunnel, displaying the determination result, and automatically sending the geological position of a risk pipeline and related information of the pipeline to a corresponding maintenance station via the wireless communication network. The evaluation method and system can effectively monitor the safety level of the gas pipeline in the tunnel, and can provide early warning information for the tunnel monitoring center in real time, thus ensuring the operation safety of the whole underground utility tunnel system.

Description

Technical field: [0001] The invention belongs to the technical field of safety prevention and control of urban underground comprehensive utility corridors, and in particular relates to a quantitative evaluation method and an evaluation system for the confidence degree of gas pipelines in comprehensive utility corridors. Background technique: [0002] Urban underground comprehensive pipeline corridor refers to the structures and auxiliary facilities built underground to accommodate two or more types of urban engineering pipelines. The urban underground comprehensive pipeline corridor organically integrates various municipal pipelines such as water supply, drainage, telecommunications, electricity, gas, and heat, and intensively lays them in the same tunnel to realize centralized management and maintenance of municipal pipelines. The comprehensive pipe gallery realizes the centralized management of municipal pipelines, and is equipped with intelligent monitoring equipment, inc...

AI Technical Summary

Problems solved by technology

Due to the particularity of the service environment of the gas pipeline in the corridor, the evaluation method of the reliability of the gas pipeline in the corridor is different from the evaluation method of the directly buried gas pipeline. The gas pipeline is laid in the pipeline corridor. Space and related facilities or structures are interspersed and avoided; on the other hand, there are still problems of reliability and compatibility between gas pipelines and pipe gallery bodies under different life cycles
