Repairing scheme for leakage of bottom plate joint of underground garage

Repairing scheme for leakage of bottom plate joint of underground garage subway The repair scheme for water leakage and plugging at the bottom slab joints of the reservoir and the method for anti-seepage treatment of the basement joint are as follows:

For water leakage at bottom plate joint of underground garage Generally, the following plugging and repair schemes can be adopted:

1. * * Conduct surface treatment first * *, such as polishing to clean the dirt on the surface and expose the new concrete surface And then carry out grouting and plugging treatment. If the leakage is serious, the leakage can be stopped with quick plugging agent first, and then the conventional waterproof treatment can be carried out.
2. * * Direct rigid flexible waterproof layer * *, which usually requires cleaning the construction base, painting rigid waterproof materials, and then pasting anti-seepage Coiled material or flexible waterproof layer.
3. * * Grouting treatment * *. For leakage points with crack width greater than 0.3mm, high-pressure grouting can be adopted. This method is applicable to the reinforcement and reinforcement of concrete cracks Very good effect.

The following suggestions are made for the anti-seepage treatment of basement joint:

1. * * Reasonably set deformation joints * *, deformation joints are an effective method to prevent basement leakage one of.
2. * * Do a good job of post cast strip construction * *, which can reduce cracks caused by temperature and shrinkage of concrete, thus preventing leakage.
3. * * Strengthen concrete quality control * * to avoid cracks caused by concrete quality problems, so as to prevent leakage.
4. * * Regular inspection and maintenance * *. For the completed basement, regular inspection can timely find and deal with potential leakage problems.

The above schemes and measures are only for reference, and the specific scheme shall be determined according to the actual situation. Repairing scheme for leakage of bottom plate joint of underground garage
