A New Drainage and Decompression System for Basement

A new drainage and decompression system for basement is proposed. The drainage and decompression system is composed of intercepting system and drainage system. The intercepting system is mainly composed of foundation pit waterstop curtain and fertilizer tank backfill clay; The drainage and decompression system consists of drainage system, water collection system, monitoring, early warning and emergency system and backwash system. The drainage and decompression system composed of four systems effectively ensures the anti-floating effect of the basement, effectively overcomes the problems of long construction period and high cost of the traditional anti-floating system, and solves the common problems of the traditional drainage and decompression method, achieving a major breakthrough in engineering technical problems.
