Maintenance of reverse hanging membrane of sewage tank

The reverse hanging membrane capping of sewage tank is the most effective method to treat the waste gas collection of sewage tank at present. After the completion of the reverse hanging membrane structure building, great attention should be paid to the maintenance to ensure the normal use, which is different from the general building. Special personnel shall be responsible for the long-term maintenance of the reverse hanging membrane building, and the problems shall be found and solved in time.

1. Maintenance of membrane structure; After the completion of the anti hanging membrane structure, great attention should be paid to the maintenance and repair to ensure normal use. Although the maintenance and repair workload of the anti hanging membrane structure is small, the problems found in the timely maintenance can be solved in time to avoid affecting the waste gas collection;

2. Regular inspection of membrane structure; Within a period of time after the completion of the reverse hanging membrane project, the production and installation unit shall be responsible for inspection and maintenance, and provide the user with maintenance manual. Within one year after the completion of the construction of the reverse hanging membrane structure, the reverse hanging membrane structure shall be subject to routine inspection and maintenance at least once. If the membrane surface is abnormal, pretension reinforcement or other measures shall be taken. If the connector is loose, it shall be fully tightened or reinforced;

3. Strict sealing; Ensure the safe connection between each edge member and the membrane surface, and the sealing between the membrane and the membrane is good;

4. Maintenance of drainage system of reverse hanging membrane structure; Check and clean the membrane surface before the rainy season and winter to keep the membrane surface drainage system unobstructed. In areas with heavy snow load, necessary emergency measures such as snow melting and snow removal shall be set to ensure the normal use of membrane structure;
