Application technology solutions for urban integrated pipeline corridors

1. What is a comprehensive pipeline corridor?

        The urban integrated pipe gallery is also called "common trench" or "public pipeline". It is a public tunnel for laying municipal pipelines such as electricity, communication, radio and television, water supply, drainage, heat, gas, etc. In the past, the above-mentioned multiple pipeline systems were built and managed separately. With the development of the city, there were many contradictions in the construction of these pipelines. The emergence of the urban integrated pipe gallery has largely solved this problem by concentrating the pipelines in various fields to achieve unified construction, unified management, and unified design. Promoting the development of the urban integrated pipe gallery can solve problems such as "road zippers". It is a people-friendly project that can effectively improve the comprehensive carrying capacity of the city, improve 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 for urban development. The monitoring of the integrated pipe gallery ensures the safety and stability of existing buildings and underground pipelines in the area affected by the underground urban pipe gallery, provides feedback information for foundation pit construction in a timely manner, and grasps the changing laws of the stability of the enclosure structure through the analysis of the pipe gallery monitoring data. It is an important part of the information construction of the project, which requires technical means to provide judgment data for controlling the impact of construction on the surrounding environment.

        Haoyuan DTS distributed fiber optic temperature monitoring system, discrete fiber optic temperature detection system, gas detection system, and DVS vibration detection system can be applied to data security detection of urban integrated pipeline corridor projects, providing strong technical safety guarantees for promoting the construction of urban underground integrated pipeline corridors, coordinating the planning, construction, and management of various municipal pipelines by the government, and solving problems such as repeated road excavation, dense overhead line networks, and frequent pipeline accidents.

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

        The integrated pipe gallery is mainly used for municipal livelihood projects such as power cables, communication cables, cable TV cables, water supply pipelines, reclaimed water pipelines, cooling pipelines, heating pipelines, gas pipelines, drainage pipelines, street light cables, garbage vacuum systems, and oil pipelines. In urban integrated pipe galleries, especially power, communication, and gas pipelines, fire accidents are prone to occur. In addition, the space of the integrated pipe gallery is small, and the efficiency of evacuating people at the entrance and exit is low. Therefore, once a fire accident occurs in the integrated pipe gallery, the hot smoke inside the pipe gallery cannot be removed in the first time, the amount of harmful gases increases rapidly, the oxygen content decreases rapidly, the narrow space causes heat to accumulate rapidly, and the fire spreads rapidly. It is difficult to extinguish and the fire is fierce, which seriously endangers the personal health of the staff. In order to nip the accident in the bud before the fire accident occurs and extinguish the fire in the first time, 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 alarm in time and extinguish the fire at the same time to ensure the safety of the operation of the urban integrated pipe gallery.
