Abstract

The invention discloses a water leakage treatment method for underground excavation tunnel construction. The water leakage treatment method comprises the following steps: (1) detecting and determining a tunnel leakage area; (2) drilling reinforced repair holes; (3) the interiors of the reinforced repair holes are cleaned; (4) preparing a leaking stoppage material and a reinforced reinforcement cage; (5) the prepared leaking stoppage material is put into the prepared reinforcing steel reinforcement cages, and then the multiple reinforcing steel reinforcement cages are inserted into the reinforcing repairing holes correspondingly; and (6) sealing the inner surface of the tunnel. According to the construction method, bubbles existing during water leakage construction can be effectively removed, the repairing effect is good, the forming speed is high, water leakage construction can be conducted in a targeted mode, construction is easy and convenient, blind and excessive repairing construction is avoided, the construction cost is greatly saved, the construction progress is shortened, and the construction efficiency is improved. The effects of accurately repairing the target and enhancing the overall structural strength of the tunnel are achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction for underground engineering, in particular to a method for treating leakage water in underground tunnel construction. Background technique [0002] In recent years, with the needs of my country's subway, highway and railway engineering construction, a large number of tunnel projects have been built accordingly. There may be cracks in the tunnel project or after the tunnel is completed. There are various types of cracks, and the reasons for the formation of cracks are also various. Faced with cracks in the tunnel, if they are not dealt with in time, they will inevitably appear. Water leakage and other conditions, if the situation is serious, will even affect the service life of the entire tunnel. For this reason, when cracks are found in tunnel construction, the corresponding leakage water treatment will be carried out in time; [0003] The leakage water treatment method in the prior a...
