Tunnel junction and culvert leakage water plugging can take the following steps:

1.Find the leak point: Before plugging the leak, you need to carefully find the leakage point and the seepage site to understand the specific situation of the leakage.

2.Clean the leakage part: clean the cement slurry layer, oil stain, dust, etc. on the surface of the leakage part.

3.Drilling: According to the location of the leakage point and the construction requirements, drill holes around the leakage site, and the general drilling depth is about 3 5 cm.

4.Set up the grouting pipe: Insert the grouting pipe into the drilled hole and use cyclohexane to plug it to ensure that there is no water seepage around the pipe.

5.Buried grouting nozzle: bury the grouting nozzle at the leakage part and fix it with special glue.

6.Preparation of grouting solution: select the appropriate material and ratio according to the water leakage situation, and stir the material evenly.

7.Pressure test: Before grouting, it is necessary to test the pressure of the pipeline to ensure that the pipeline does not seep water.

8.Start grouting: adjust the grouting pressure and speed according to the actual situation, and carry out grouting according to the principle of sequential grouting from one side to the other.

9.Observation: After the grouting is completed, it is necessary to observe for a period of time to ensure that no leakage occurs.

If the above methods do not solve the problem, it is recommended to seek the help of the person who plugs the leak. At the same time, be sure to clean all tools and materials after processing to ensure that there are no hidden dangers.
