Construction management of modern urban sewage pipe network?

What specific contents are included in the construction management of modern urban sewage pipe network? The following Zhongda Consulting Bidding Teacher will answer your questions for your reference.

The construction of municipal sewage pipe network is not only a basic project that a city should have, but also an important part of a city's public works. It is a pipe network system whose main job is to collect sewage and process it. Therefore, it is one of the main methods to improve the urban environment and a source of power to promote urban economic development. Therefore, scientific and rigorous urban sewage pipe network planning will not only improve the quality of the urban environment and improve the ability to serve the public, but also increase urban economic development.

1. Characteristics of the municipal sewage pipe network project

1. The municipal sewage pipe network project is located on both sides of the urban road, close to various buildings, with many people passing by, and the construction is underway The area is small;

2. There are many obstacles on the ground. Due to the unreasonable planning of underground pipelines, various pipelines are intertwined, the coordination workload is large, and the construction is difficult;

3. Sewage is drained by gravity. In order to prevent backflow of sewage and other phenomena, the elevation requirements of the sewage pipe network are relatively high;

4. The trenches of the sewage pipe network are deep and there are many safety hazards;

5. Sewage contains various harmful substances. If leakage occurs, it will cause serious pollution to groundwater and directly affect a city’s water resources. Therefore, the strictness of the pipe network is required;

6. The sewage pipe network project is an underground construction project. In order to avoid ground depression after construction, the requirements for backfill soil during construction are relatively high.

2. Problems in municipal pipe network construction and management technology

1. Pipe network management is lacking, and there are serious problems in the handover of responsible units.

① After the land property rights structure of the responsible management unit changes, the land use rights are freely controlled by the owner, which leads to unclear ownership and maintenance responsibilities of dedicated pipelines and lack of pipeline network management; ② With some When industries, mines and enterprises close down, their dedicated pipe networks will lose normal maintenance;

2. The pipeline situation is complex and there are problems such as lack of handover of drainage facilities

my country's newly built road drainage Facilities, due to inconsistent standards and the large number of construction units, have uneven construction quality, resulting in criss-crossing sewage pipe networks and difficult handovers.

3. The responsible unit is irresponsible and the later maintenance is not in place.

The municipal sewage pipe network is an underground project. During excavation and other engineering operations, due to improper operation, the drainage pipe network will often be damaged. If there is a problem or damage to the drainage system, For example, during the construction process of underground pipelines, drainage facilities are often damaged. Due to the long response period after problems with drainage pipelines, the responsible units generally cannot deal with them in time after the problems are discovered, resulting in passive drainage management and pollution of the urban environment.

4. The inspection and monitoring of the municipal sewage pipe network is not in place.

In the daily use of the municipal sewage pipe network delivered for use, there is a clear lack of inspection and monitoring by the competent department, and the situation of "no one to maintain and no one to manage" often occurs, which seriously affects the municipal pipe network. role in urban sewage discharge.

3. Countermeasures to solve municipal pipe network construction and management problems

1. Professional drainage planning based on scientific design standards can guide the construction of sewage pipe networks . However, the current drainage planning in most cities still lacks scientificity. One of the reasons is that when leaders change, the ideas will also change. The previous planning idea is about to be abolished during the design, and the new planning idea has not yet taken shape, making the planning lack of continuity; The second reason is that the plan is too exaggerated. The plan seems grand but is actually too shallow in depth, making actual construction difficult. The third reason is that the planning and design of various areas in the city cannot be unified, and the overall plan cannot smoothly follow the regional plan. The fourth reason is that there is a lack of planning. Rigor, some plans have clearly stated the construction of sewage pipe networks, but pipeline construction and construction are often interrupted midway due to individual departments arbitrarily canceling pipeline construction or lack of investment, which will have an impact on the drainage of surrounding buildings in the later stages of construction, and even serious It restricts the overall planning of the city.

Therefore, an organization should be established to carry out overall planning, unified coordination, and professional planning and design. Taking integrity, scientificity and rigor as the starting point of planning, it can increase the scope and depth of planning. In the planning, the construction and planning of new urban areas should be carried out at the same time, and the old urban areas should be mainly renovated and retained as a supplement. For some chemical companies and industrial enterprises in the urban area, reasonable sewage treatment planning should be carried out, and for township drainage planning Regional drainage planning should be planned and designed based on the specific conditions of the region. It is necessary to view the planning of the sewage pipe network as a whole, coordinate the planning between suburbs, urban and rural areas, and urban areas, and eliminate blank areas and blind spots in the planning. And strengthen the construction of sewage treatment facilities and improve treatment capacity. Once the plan is established, it should be used as a guide for continuous and uninterrupted construction and should not be stopped midway due to leadership changes.

2. Further strengthen the unified leadership of the sewage pipe network work and achieve overall planning and sustainable development.

In accordance with the relevant regulations of the city public administration department, using system integration as the main method, the existing functional departments of sewage treatment are tested, screened according to the degree of coupling between them, and the degree of coupling is selected. High-level functional departments will be reorganized and upgraded to new functional departments, while relatively low-level functional departments will be established with corporate modules to improve their coupling. 3. Transform government functions and provide strong support for the construction of municipal sewage pipe networks.

As a third party, the government should play its regulating role so that pipeline networks belonging to different assets can work together and play a more beneficial role. In addition to formulating some laws and regulations to restrict it, the following work should also be carried out:

(1) Provide economic support. The construction and planning of drainage pipe networks are directly related to the quality of life of urban residents, as well as urban development and environmental infrastructure. Therefore, the government should take different economic measures to support and assist the construction of pipe networks to ensure Its functioning normally.

(2) Strengthen monitoring. The government can monitor the drainage pipe network from the following two aspects: One is to monitor the dedicated pipe network. Monitoring the dedicated pipeline network can make up for the lack of punishment power for the pipeline network operating units. The government can use some advanced technologies to monitor the dedicated pipeline network, and the government can also conduct centralized monitoring of some pipeline network enterprises with scattered owners. , to avoid some vicious disputes between enterprises and properties. The second is to monitor the drainage backbone network. The government monitors the operation of the pipeline network as an asset owner, and at the same time monitors it as a manager and handles some complaints. This can promote some sewage treatment agencies to better complete the treatment work.

4. Strengthen source management and gradually establish files of key sewage discharging households in conjunction with the drainage permit system.

During the operation of the sewage pipe network, managers often encounter some problems of illegal discharge and excessive discharge. , these problems have brought a lot of trouble to managers. The difficulty with this type of problem is that it is difficult to find the source of the emission, and this type of problem will have a serious impact on the sewage pipe network and sewage treatment plants. Among them, combined throttling pipelines will also pollute rivers and drinking water sources, causing safety accidents. Therefore, it is necessary to promote the comprehensive acceptance of some construction projects, and add sewage audit, takeover filing and discharge permit systems to some of the currently implemented acceptance mechanisms. Summarize and collect the water quality, water quantity, adulterated pollutants and discharge outlet settings discharged from the discharge sources, establish discharge files for unified management, and classify discharge sources according to the degree of pollutant impact and risk level, so as to achieve Control and management of emission sources ensure the smooth operation of sewage pipe networks.

5. Standardize the construction behavior of sewage pipeline construction enterprises, and strictly manage the acceptance of project completion and project handover.

As far as the current sewage pipeline construction is concerned, there are still some traditional quality problems: for example, some construction parties modify the drawings according to their own intentions, so that the completed drawings are not consistent with the construction drawings; for example Sewage pipe interfaces use joints of poor quality, resulting in some disconnections and misalignments. In addition, in order to blindly pass the closed water test and water stop test, heads are randomly installed in the pipes of the inspection wells, causing problems with the drainage capacity of the pipes; Another example is when the head is dismantled incompletely, and the treatment is hasty and ineffective. When working on the road base, in order to reduce the workload, stones, soil, ash and other debris are filled into the inspection well, and some even bury the inspection well, causing the It no longer exists, causing problems such as settlement around the inspection well. These quality problems will cause hidden dangers to the normal operation of the sewage pipe network, and will complicate the management and inspection of staff. Therefore, it is necessary to supervise and manage the construction parties during construction, and some roads and municipal projects are supporting The construction of sewage pipe network requires us to pay more attention. Generally speaking, when handing over property rights, we can require the construction party to provide more completion data, actual drawings and revised drawings, completion inspection reports and closed water test reports, etc., and at the same time personally inspect the quality of pipelines and inspection wells, and conduct some inspections on some seals. Pay special attention to the heads and joints. If there is a quality problem, consult with the construction company in time, and you can only decide to accept it until the problem is solved.

The urban drainage project can be said to be an important construction project in municipal engineering and one of the infrastructures that serve the public. It can effectively help the city drain and prevent waterlogging, and can also coordinate the city's sewage. Emissions are of great help in improving the urban environment and saving water resources, and play an important role in promoting urban construction and social and economic development. Therefore, we need to strengthen the management of the sewage pipe network to ensure its safe and smooth operation, so as to provide better services to the public and provide sustained impetus for economic development.
