UNDERGROUND WATER DRAINAGE OF STRUCTURE WITH POROUS PIPE

摘要

PURPOSE: A process for underground water drainage of a structure is provided to prevent settlement of ground supporting the structure caused from the drainage and to efficiently use the underground water by applying porous pipe. CONSTITUTION: The process is accomplished by an porous pipe assembly including inner drainage pipes(100) and outer drainage pipes(200). Each of the inner drainage pipes(100) is an porous pipe to receive inflow of the underground water and to be connected to each of the outer drainage pipe(200). The outer drainage pipe is laid outside an outline(G) for building a structure as another porous pipe with varied shapes and collects the underground water. Alternatively, perpendicular drainage pipes(300) flows the collected underground water out of the outer drainage pipe(200) above the ground.
