Underground civil air defense shrinkage joint waterproof plugging basement floor joint plugging treatment
The following methods can be used for the waterproof plugging of underground civil air defense shrinkage joints and the plugging treatment of basement floor joints:
1.Grouting water stop: pre-embedded grouting pipes on the frontal wall of the basement outer wall, and pay attention to setting a certain number of grouting valves at the bottom of the wall to facilitate later grouting . When the grouting pipe leaks at the junction with the wall concrete, the grout can flow into the cracks. The honeycomb inside the concrete is filled with high-pressure grouting to stop the leakage problem in time.
2.Leakage treatment: chisel open the water seepage part or focus on finding the leakage part, and then directly block the leakage point with waterproof plugging material. The basement roof should do a good job in the construction of waterproof membrane and waterproof coating to ensure quality. For the construction joints, the expansion rubber strip can be used to waterproof to achieve the waterproof effect.
3.Strengthen the control of the construction process: ensure the construction quality of steel bars, templates, roofs, bottom plates, construction joints and other parts. After completion, various inspections should be carried out strictly to ensure that there is no leakage.
4.Strengthen maintenance management: After the completion of the waterproof layer, it is necessary to go through a period of water storage inspection, and there is no leakage before subsequent construction can be carried out. In the later use process, it is also necessary to strengthen maintenance management to ensure the waterproof effect.
The above methods are for reference only, it is recommended to consult with a construction or waterproofing engineer to obtain accurate information.
Basement floor joint plugging treatment can be operated as follows:
1.Clean up the surface stains before construction, clean the uneven places on the surface to ensure a smooth surface.
2.To apply waterproof paint, you need to apply it multiple times, with an interval of 2 to 3 hours between each pass, and you need to make sure that the paint is mixed evenly.
3.Where the gap is too large, it is necessary to select appropriate plugging materials, and combine several materials to brush or scratch according to the construction requirements. For some places where the gap is too large, it can be treated by pouring rubber.
4.For the deformation joint, apply two layers of waterproof paint, bury a waterstop in it, and protect the waterproof layer with cement mortar.
5.Use high-quality materials and apply a special waterproof coating on top of the material for protection. At the same time, the above steps need to be used flexibly according to the structure of the basement and the location of the leakage.
If you have any questions or are unsure about the above steps, please seek help from someone.
