Flexible seam sealing method for water of hydraulic concrete expansion joint
The invention relates to a flexible seam sealing method for water of a hydraulic concrete expansion joint, which belongs to a seam sealing method for the hydraulic concrete expansion joint resistant to outer water seepage pressure and temperature shrinkage. Water leakage is prevented initially, a hole is opened for water diversion, the water leakage is blocked off basically, temporary water stop is completed, an embedded type joint cutting processing mode or a superficial direct anchoring type processing mode is adopted, the initial setting time of the joint material is 3 hours, the concretion time is 25 to 30 days, a brake valve is closed, and the treatment is over. The advantages are that: the problem that leakage is caused as the width of the expansion joint changes with the change of temperature is solved, as the expansion joint is sealed by a flexible material, the expansion joint water stop can change with the temperature, and does not influence the water stop effect; construction in a moist environment or even the construction with water can be conducted. The investment is saved. As damages do not exist, and are low or tiny, the workload is small, the project operation is not influenced, and the project investment is saved obviously.
