Technical solution for the application of urban comprehensive pipe gallery

1. What is a comprehensive pipe gallery?

        The urban integrated pipe gallery is also called "common ditch", "public pipeline", etc. It is a kind of public tunnel for laying electric power, communication, radio and television, water supply, drainage, heat, gas and other municipal pipelines. In the past, the above-mentioned multiple pipeline systems were constructed and managed separately. With the development of cities, there were many contradictions in the construction of these pipelines. The emergence of urban integrated pipeline corridors solved this problem to a large extent. Centralize pipelines in various fields to achieve unified construction, unified management, and unified design. Promoting the development of urban integrated pipe corridors can solve problems such as "road zipper". It is a benefiting project that can effectively improve the city's comprehensive carrying capacity, increase the utilization rate of underground space, ensure the quality of new urban development, and promote the process of urban development. It is a new ladder of urban development. Comprehensive pipe gallery monitoring ensures the safety and stability of existing buildings and underground pipelines in the area affected by the underground city pipe gallery, and provides timely feedback information for foundation pit construction. Through the analysis of pipe gallery monitoring data, the stability of the envelope structure changes law , Is an important part of project information construction, it needs technical means to guarantee it, and provide judgment data for controlling the impact of construction on the surrounding environment.

        Hoyatek DTS distributed optical fiber temperature monitoring system, discrete optical fiber temperature detection system, gas detection system, DVS vibration detection system can be applied to the data security detection of urban integrated pipeline gallery project, in order to promote the construction of urban underground integrated pipeline gallery, and coordinate the government The planning, construction and management of various municipal pipelines provide strong technical safety guarantees to solve the problems of repeated excavation of roads, dense overhead line networks, and frequent pipeline accidents.

2. The essence of optical fiber temperature detection system: explosion-proof, fire prevention, perimeter safety, and gas leakage prevention

        The integrated pipe gallery is mainly used for: power cables, communication cables, cable television cables, water supply pipelines, reclaimed water pipelines, cooling pipelines, heating pipelines, gas pipelines, drainage pipes, street light cables, garbage vacuum systems, Municipal and people’s livelihood projects such as oil pipelines. In the urban integrated pipeline gallery, especially the power, communication, and gas pipelines, fire accidents are prone to occur. In addition, the integrated pipeline gallery has a small space and the efficiency of evacuation of people at entrances and exits is low. Therefore, once a fire accident occurs in the integrated pipe gallery, the hot smoke inside the pipe gallery cannot be eliminated in the first time, the amount of harmful gases increases rapidly, the oxygen content decreases rapidly, and the narrow space leads to rapid heat accumulation and rapid fire spread, which is difficult to fight and rescue. The fierce fire and other characteristics seriously endanger the personal health of the staff. In order to kill the accident in the cradle before the fire accident occurs, and extinguish the fire immediately, it is necessary to set up an automatic fire alarm system and link the fire protection system. Once a fire problem is found, the system will promptly call the police and extinguish the fire at the same time to ensure the city The safety of integrated pipe gallery operation.
