How to do a good job in the construction safety of the sewage pool leakage stoppage project

News Abstract: when the external scaffold is used in the leakage stoppage and waterproof engineering construction of the sewage pool, the external scaffold should be inspected comprehensively before the application to meet the requirements.

When the external scaffold is used in the leakage stoppage and waterproof engineering of the sewage pool, the external scaffold shall be inspected comprehensively before application to meet the requirements. If the steel pipe scaffold is used for vertical climbing, it should be connected to the roof immediately. If a herringbone ladder is used to climb or go down the pit, the ladder shall be made of solid raw materials and shall be firmly connected with the fixed parts. If it is a movable herringbone ladder, there should be anti-skid measures on the ground, and some people should take care of it, not to mention the herringbone ladder and steel pipe scaffold used to transport lifting objects.
What are the common problems and solutions when plugging the sewage pool?
1. In the whole process of plugging the sewage pool, water should be discharged first. When the pressure increases, the lack of concrete will leak. The internal and external offices of the company are used to stop leakage, and the moisture-proof mixed mortar putty for the bottom plate, cast-in-place slab and outer wall of the reservoir is 20 mm thick.
2. Under the condition that the leakage problem is not serious, the plugging agent can be selected and used according to the proportion of cement mortar. This kind of method can produce waterproof membrane, and the practical operation is relatively simple, and the moisture-proof characteristics are also very good. There are generally two problems in plugging the sewage tank
1. The leakage stoppage of sewage pool is mainly caused by the leakage of settlement joint. If the settlement joint is not cleared at the construction site, the concrete strength will not reach the standard.
2. When the waterproof concrete is poured into the reservoir, small total area honeycomb and root rot will appear after the slab is removed due to the concrete mortar consistency not conforming to the requirements and insufficient vibration. Only the surface is easy to solve, and the cleaning is not careful.
