New material underground structure leakage stoppage construction technology
A new material underground structure leakage stoppage construction technology includes the following steps that firstly, cleaning is performed; secondly, drilling and drainage are performed; thirdly, a grouting guide pipe is installed; fourthly, cracks are sealed; fifthly, grouting is performed, wherein ultra-fine cement slurry materials are adopted for grouting, water leakage is reduced or disappears, then permeable crystallization grouting materials are injected to plug a tiny water seepage channel, and finally epoxy resin grout is injected for reinforcement; sixthly, a nozzle is detached; and seventhly, sealing is performed. Through a traditional leakage stoppage method, only obvious cracks can be plugged. According to the new material underground structure leakage stoppage construction technology, ultra-fine cement slurry is adopted for plugging the tiny cracks, the phenomenon that only the temporary problem is solved and the fundamental problem is not solved is effectively avoided, and the effect of fundamentally suppressing structural crack water leakage is achieved. By means of the method, repeated construction of leakage stoppage operation can be avoided, the effects of saving cost of labor, machines, materials and the like are effectively achieved, and good economic benefits are achieved.
