Induced drainage method of leaks in cracks of structures

摘要

The present invention relates to a method for inducing drainage of leaks in cracks of a structure, which is connected to a collecting pipe installed at a leak point of cracks in a structure, such as sand or non-woven fabric in a porous pipe for induction drainage that sends leaked water to a drain. By filling the filter material, it is possible to prevent the phenomenon of ground subsidence to the cavitation in the back of the structure by the inflow and loss of fine granules on the back of the structure together with the leaking water or inside the ground around the structure.
