Underground space waterproof curtain leakage monitoring device

Abstract

The invention discloses an underground space waterproof curtain leakage monitoring device. The waterproof curtain leakage monitoring device comprises an inner side sensing system composed of a plurality of inner side sensing modules, an outer side optical fiber system and a data terminal; each inner side sensing module comprises a composite wet pressure sensor, a single-chip microcomputer and a wireless communication module; the composite wet pressure sensors, the wireless communication modules and the single-chip microcomputers are connected; the outer side optical fiber system comprises micro-motion sensing optical fibers and an optical time domain reflectometer, and the micro-motion sensing optical fibers are arranged along different monitoring areas and connected with the optical timedomain reflectometer; and the optical time domain reflectometer and the inner side sensing systems are connected with a data terminal. According to the invention, tiny leakage points of a waterproof curtain can be effectively and accurately monitored, the leakage degree can be effectively and accurately evaluated, and dangerous events are avoided.

Description

technical field [0001] The invention relates to the technical field of water-stop curtain leakage monitoring for underground space structures, in particular to a water-stop curtain leakage monitoring device for underground space. Background technique [0002] The water-stop curtain as an underground space structure often suffers from different degrees of leakage due to construction techniques or construction problems. When there is a difference in water head inside and outside the foundation pit, there will be different degrees of water leakage. The leakage of the water-stop curtain will have a great impact on the foundation pit itself and its surrounding environment. If the leakage is serious, it may also cause quicksand , Piping phenomena, leading to ground subsidence, pipeline rupture, building cracking, etc., and even life-threatening, so the leakage monitoring of the water-stop curtain in the underground space is particularly important, especially the precise location o...
