Replaceable device for monitoring water seepage of prefabricated assembly type subway station connectors

Abstract

The invention provides a replaceable device for monitoring water seepage of prefabricated assembly type subway station connectors, and belongs to the technical field of underground engineering. A water seepage monitoring device formed by combining a concrete member, water-swelling rubber and a pressure sensor is arranged on the sides, close to underground space, of splicing members. The pressure sensor is embedded into the water-swelling rubber which is embedded in a reserved groove of the concrete member, and the water-swelling rubber is not connected with the concrete member at all. The concrete member is embedded in a reserved groove of the splicing members and not connected with the splicing members at all. The replaceable device for monitoring water seepage of the prefabricated assembly type subway station connectors has the beneficial effects and advantages that waterproofness of the integral structure cannot be affected by arrangement of the device; after the connectors are subjected to water seepage, the water-swelling rubber swells, signal data of the pressure sensor changes, and effective monitoring can be conducted on the portions subjected to water seepage; the concrete member and the water-swelling rubber can be conveniently disassembled, assembled and replaced, and the operating cost of an underground structure is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, relates to the waterproofing of joints of prefabricated and assembled subway stations, and in particular relates to a replaceable device for monitoring water leakage of joints of prefabricated and assembled subway stations. Background technique [0002] With the development of China's underground engineering, urban subways have gradually become the preferred mode of urban transportation. As a new construction technology of subway station, prefabricated subway station has been paid more and more attention by people because of its fast construction speed and good construction quality. However, due to the unique assembly method adopted by the structural components of the prefabricated subway station, the joints of the components become weak waterproof areas. Therefore, the monitoring of water leakage at joints should be strengthened, in order to find the location of water leakage as...
