Repair construction method of deformation joint leakage in basement

Abstract

The invention provides a repair constructing method of basement deformation joint leakage. On the basis of water forced blockage and pressure ejection for water plugging, a water-swelling sealing rod and an external attached waster stop (a steel plate is fixed together with a chemical bolt) are additionally provided, a drainage groove is provided, and water is introduced into a plash for processing leakage of a basement deformation gap. The repair constructing method is safe and environmentally-friendly, can meet the use and safety requirements of a building, can be used for effectively repairing leakage of the basement deformation gap, achieves combination of prevention and drainage, and is good in comprehensive treatment and leakage repairing effect.

Description

technical field [0001] The invention relates to a building construction method, in particular to a repair construction method for leakage of basement deformation joints. Background technique [0002] At present, the leakage of deformation joints in the basement is quite common. Generally, there are two forms of leakage water in the deformation joints of the basement. The first is that the embedded steel plate at the deformation joint is seriously corroded, so that the leakage water penetrates the steel plate and connects with the concrete. leaks through the gaps. The second reason is that the external waterstop at the deformation joint is damaged or the fixed steel plate is not compacted, and the leakage water seeps through the damaged part of the waterstop or the bolt hole. In addition to the above two reasons, the reasons for the leakage of the deformation joints include: the original embedded waterstop did not take fixing measures, which caused the concrete to be squeeze...

The second is due to the damage of the external waterstop at the deformation joint or the uncompacted fixed steel plate, the leakage water seeps through the damaged part of the waterstop or the bolt hole

In addition to the above two reasons, the reasons for the leakage of the deformation joints include: the original embedded waterstop did not take fixing measures, which caused the concrete to be squeezed and deformed during pouring; the concrete wrapping on the two wings of the original embedded waterstop was not Strict or vibrating is not dense; the reinforcement is too dense, the concrete pouring method is improper, resulting in the aggregate being concentrated in the lower part; the deformation and displacement of the deformation joint is relatively large, and the original embedded waterstop is pulled and cracked

[0003] The existing treatment is to use the method of "pressure grouting" for sealing, but because the deformation joint is in a dynamic environment, this sealing method can only be effective in a short period of time, once the part is under the action of deformation, expansion and contraction If relative displacement occurs, the grouting sealing material will be cracked, resulting in failure of repair and treatment
