Underground pipelines are like the "blood vessels" of the city, the infrastructure and lifeline to ensure the normal operation of the city, and the normal operation of the underground pipeline is related to the health and well-being of the city. At the ** economic work conference held in 2023, the general secretary emphasized that the construction of the urban underground pipe network is the "lining" project of the city, "our Chinese tradition is to 'face', the actual 'face' and 'lining' should be together, and the 'lining' should be more important."
This year, in order to further implement the "Lizi" project, all localities are focusing on accelerating the transformation of the underground pipe network. Xinhua News Agency reporters recently learned from the Ministry of Housing and Urban-Rural Development that in the future, China will transform more than 100,000 kilometers of underground pipelines every year.
The person in charge of the relevant department of the Ministry of Housing and Urban-Rural Development said that the underground pipe network includes municipal public pipelines such as water supply, rainwater, sewage, reclaimed water, natural gas, heat, electricity, and communications within the city to meet the needs of life and production. At present, the length of water supply pipelines in cities across the country has reached 110300,000 km, the length of drainage pipes is 91350,000 km, the length of the gas pipeline is 98040,000 km, the length of heating pipelines is 49340,000 km.
It is understood that this year, China will vigorously promote the transformation of urban underground pipe networks, implement urban drainage and flood prevention capacity improvement projects, and further promote the construction of urban lifeline safety projects.
* The government will issue an additional 1 trillion yuan of national bonds to support post-disaster recovery and reconstruction and improve disaster prevention and mitigation capabilities, of which the urban drainage and flood prevention capacity improvement project is an important content.
Subsequently, various places have stepped up efforts to promote the shortcomings of the construction of urban underground pipe networks, such as Jiangsu, Jilin, Zhejiang, Hebei, Anhui, Guangdong and other places have issued the 2024 financial urban pipe network and sewage treatment subsidy funds in advance, and the policy "warm wind" is blowing frequently, and the transformation efforts are increasing, it can be seen that the underground that we cannot see is ushering in new development opportunities.
Founded in 1992 as a wholly-owned subsidiary of Digital Politics, Baoding Jindi is one of the earliest high-tech enterprises engaged in underground pipeline technical services in China, and has a number of core qualifications such as national surveying and mapping grade A and municipal level II. The company's business covers underground pipe network, flood control and drainage, black and odorous water bodies, water supply, gas, underground municipal infrastructure, urban lifeline and other fields. After more than 30 years of development, it has formed a comprehensive industrial pattern of "pipeline detection, hidden danger investigation, detection and repair, engineering supervision, topographic map surveying and mapping, information software, normalized operation and maintenance, pipeline robot R&D and manufacturing", which can provide one-stop comprehensive services of engineering services, information software, and normalized operation and maintenance. With the support of these strong policies and stable funds, Baoding Jindi is willing to work together with all localities to accelerate the transformation of the underground pipe network and comprehensively start the battle of the pipe network.
* The government will issue an additional 1 trillion yuan of national bonds to support post-disaster recovery and reconstruction and improve disaster prevention and mitigation capabilities, of which the urban drainage and flood prevention capacity improvement project is an important content.
The top priority of promoting the transformation of the pipeline network is to fully grasp the location attributes and laying status of the urban underground pipelines, establish an underground pipeline network information database, and form an intuitive electronic map of the hidden pipelines, so that the numbers are clear, the situation is clear, and the numbers are accurate. At the same time, comprehensively investigate the defects such as mixed connection, damage, and leakage in the pipeline, so that all pipe network problems can surface, and ensure that the problem pipe network rectification has "zero omission".
Jindi has found out the bottom number of underground pipelines in 31 provinces and cities across the country, continuously overcome difficulties in the process of project implementation, studied new methods and new processes, independently developed a pipeline mobile data acquisition system, realized the integrated construction of internal and external industries, and has the ability to implement tens of millions of projects and more than 3,000 practical experience in projects.
In terms of pipe network diagnosis and investigation, the problem is accurately located by combining the topological relationship of the pipe network, combined with the diagnosis of water quality and quantity and other means. Through dredging detection, the specific problems existing in the pipe network are found, so that the location of the pipeline can be "clearly detected", the operation status is "accurately diagnosed", and the defects are "detected", so as to realize the scientific treatment of the drainage system and achieve the treatment goal of "treating both the symptoms and the root causes".
Underground pipelines are in disrepair and overloaded, resulting in different degrees of structural defects and functional defects, and there are two methods for the treatment of defects: excavation repair and trenchless repair. Traditional excavation needs to "disembowel" the road surface, which has a great impact on urban traffic, the environment and commercial activities. Trenchless restoration construction occupies a small area, has a short construction period, is safe and environmentally friendly, and has been recognized by the United Nations Environment Development Programme as a "friendly messenger of the environment" technology.
At present, Jindi's trenchless repair technology includes: stone slurry spraying repair, ultraviolet curing repair, thermoplastic molding and fragmented pipe repair, and local repair technology includes: local resin curing, stainless steel quick lock, double expansion ring and steel lining A variety of repair processes.
Taking advantage of the "spring breeze" of the accelerating transformation of the underground pipe network, Baoding Jindi will anchor the pain points and difficulties of urban pipe network safety, focus on the transformation of the underground pipe network, and use 32 years of experience in the pipeline industry to carefully build the underground pipeline technology service industry chain, accelerate the pace of urban pipe network transformation, and grasp the "lining" to support the "face".
