1、 Industry Overview

From the perspective of urban construction level, 293 cities (including prefecture level and county-level cities) have built underground pipe galleries. Among the cities that have built new pipe galleries with a length of 20, 7 are pilot cities. The rest of the cities are mainly large cities, as well as small and medium-sized cities such as Hancheng and Hanzhong. Recently, the State Council issued a package of policies and measures to stabilize the economy, which proposed 33 measures to stabilize the economy. Among them, there is a specific requirement to continue promoting the construction of urban underground comprehensive pipe galleries according to local conditions.

According to the report on the market competition strategy and future development potential of China's urban underground pipe gallery industry from 2022 to 2028, under the downward pressure of the "triple pressure" on the domestic economy in 2022, the construction of comprehensive pipe galleries has been reintroduced. As a new type of urban infrastructure investment with a large investment scale, it is expected to shoulder the task of economic driving. At present, multiple provinces and cities have successively released construction plans for comprehensive pipe galleries during the 14th Five Year Plan period. From the perspective of planning, each province has tailored its own situation, adhered to the positioning of urban development and the needs of construction and development, and promoted the construction of urban comprehensive pipe galleries according to local conditions.

2、 Industry pain points

The construction of underground comprehensive pipe galleries is actually not a new thing. In order to ensure both construction and maintenance, the pipe gallery adopts the "investment+construction+operation" model, which integrates investment, construction, and operation. "It does not mean that investment and construction are enough. We also carry out the operation of the pipe gallery, especially for accidents such as sewage pipeline explosion and poisoning. Therefore, to ensure the safe and smooth progress of the comprehensive pipe gallery construction project and the safety of construction personnel and surrounding people, the detection and monitoring of toxic and harmful gases is of utmost importance.

3、 Solution

1. Overview of the plan

The following solutions have been developed to address the pain points of the underground pipe gallery gas monitoring system solution.

Main monitored gas factors: methane, oxygen, hydrogen sulfide, carbon monoxide and other gases.

Monitoring locations: comprehensive warehouse (high-voltage cables, communication optical cables, water supply pipes, medium water pipes), sewage tank (sewage pipes), natural gas tank (natural gas pipeline), etc

Data monitoring system: The data monitoring system mainly consists of data servers, display screens, and other components.

Recommended equipment:

By installing intelligent gas detection devices (detectors), real-time monitoring of toxic and flammable gas data in the pipeline gallery is carried out, and the accident ventilation equipment in the accident section and adjacent sections of the cabin is activated in conjunction.

Our company will actively respond to the new national economic measures, comply with the principle of "safety and prevention first" in the "Work Safety Law of the People's Republic of China", deeply implement the relevant provisions of the "Technical Regulations for Construction Safety of Highway Engineering" (JTJ076-95), comprehensively strengthen the adoption of various effective protective measures in tunnel construction operations, do a good job in ventilation, lighting, dust prevention, waterproofing, cooling, and prevention of toxic and harmful gases, protect environmental hygiene, ensure the health and production safety of construction personnel, do a good job in enterprise safety production, do a good job in gas detection and monitoring, and safeguard the safety of construction personnel and surrounding people!
