In our daily life, the sewer is the "first vein" of the city, and its smooth flow directly affects the environmental sanitation and the quality of life of residents. When faced with the problem of sewer blockage, professionals will adopt a set of scientific construction plans for dredging.
First of all, according to the degree and location of the blockage, it is divided into two methods: physical dredging and chemical dredging. Physical dredging mainly uses professional pipe cutting machines, high-pressure washing vehicles and other equipment to mechanically crush and remove hard or partially blocked objects; Chemical dredging uses detergents containing acidic or alkaline ingredients to dissolve organic substances such as oil and hair, soften them and discharge them into the collection system.
Secondly, during the construction process, the construction personnel need to follow the safety operation procedures, wear protective equipment, ensure the operation specifications, and avoid secondary pollution of the human body and the environment caused by chemicals. At the same time, temporary drainage facilities need to be set up to ensure that the normal drainage of the surrounding area will not be affected during the construction period.
Finally, after the construction is completed, it is necessary to carry out acceptance and testing to confirm that the sewer has been restored to unobstruction, and complete the disinfection treatment after cleaning to prevent the growth of germs. Regular maintenance and inspection of sewers to prevent similar problems from occurring is a key part of maintaining the healthy operation of urban sewers.
To sum up, the dredging sewer construction plan is a comprehensive project involving technology, environmental protection and public safety, which ensures the sustainable development of the city and the improvement of the quality of people's life through scientific implementation.
