Crack leakage treatment in sewage treatment tank Expansion joint leakage repair in pump room
For the crack leakage repair of the sewage treatment tank and the expansion joint of the treatment pump room, you can refer to the following steps:
1.Crack leakage repair in sewage treatment tank: It is recommended to use the method of grouting to fill the leakage. First, inject slurry on one or both sides of the crack in the pool, and the injected slurry should have low viscosity and good fluidity. Commonly used materials are cement slurry, epoxy resin slurry, polyurethane, etc. While injecting the slurry, stir constantly to prevent the slurry from forming a blockage after hardening. Stir well and use it as soon as possible to prevent curing. It can also be considered to paste non-woven fabric or mesh cloth on the inside of the pool wall, or add steel wire mesh during concrete construction to enhance the strength of the pool wall and achieve the purpose of preventing cracks.
2.Leakage repair of expansion joints in the pump room: waterproof coatings, such as K11 waterproof coatings, JS composite waterproof coatings, etc., can be used to paint more than twice. It is also possible to use expansion joint waterstops for construction, but pay attention to the installation of waterstops firmly and accurately. At the same time, the choice of sealing materials is also very important, and it is necessary to choose materials that are suitable for the environment of the pump room, such as polyurethane sealing paste.
The above suggestions are for reference only, and you need to choose the appropriate treatment method according to the actual situation. For more information, please consult a person. The following steps can be referred to to the expansion joint leakage repair of the pump room:
1.Clean up the cracks: You need to clean up the debris and stains around the cracks to ensure that they are dry and tidy.
2.Slotting: Use tools to make slots at the crack position, the depth and width of the slotting need to be adjusted according to the actual situation, and the treatment of the notch needs to be smooth.
3.Permeable cement painting: After the groove is opened, the cracks are coated with cement, and the waterproof cement mortar can be selected for painting, which can play a basic role in filling the leakage.
4.Polyurethane plugging filling: Polyurethane plugging and filling is carried out on the surface of the cement mortar after being painted, which can play a waterproof role. After the polyurethane is completely dry, multiple closed water tests are carried out to check whether the leakage point exists.
5.Make a protective layer: After the leakage treatment of the expansion joint is completed, a protective layer needs to be made on its surface, and materials such as plastic film can be selected.
6.Perform the closed water test again: The closed water test should be carried out again to check whether the expansion joints of the pump room have been properly treated.
Throughout the process, safety needs to be observed, especially when using polyurethane for plugging and filling, avoiding direct contact. In case of contact, it should be washed immediately. It is recommended that maintenance personnel operate when dealing with water leakage problems, so as not to cause more problems due to improper operation by themselves. The above steps are for reference only, and it is recommended to adjust them according to the specific situation of the pump room and the suggestions of personnel.
