Prefabricated assembled subway station tenon-and-groove connector capable of monitoring water leakage

Abstract

The invention discloses a prefabricated assembled subway station tenon-and-groove connector capable of monitoring water leakage, and belongs to the technical field of underground construction. The technical scheme is that the prefabricated assembled subway station tenon-and-groove connector is formed through cooperation of a tenon component and a groove component; three layers of rubber gaskets are arranged at the connection part of the tenon component and the groove component; the upper and lower layers of the rubber gaskets are elastic rubber gaskets; the middle layer of the rubber gaskets is a hydrophilic expansion rubber gasket; a pressure sensor is embedded in the hydrophilic expansion rubber gasket; the upper layer elastic rubber gasket is pasted on the tenon component; the lower layer elastic rubber gasket is pasted on the groove component; the hydrophilic expansion rubber gasket is pasted on the lower layer elastic rubber gasket; after water leaks out of surrounding rock, the hydrophilic expansion rubber gasket expands when encountering water, and the pressure at the connector part is increased, so that the problem that a clearance is formed due to the fact that the pressure between the elastic rubber gaskets is insufficient due to overlarge water pressure can be effectively prevented; and besides, the hydrophilic expansion rubber gasket expands when encountering water, the pressure at the connector part changes, signal data of the pressure sensor changes, and water leakage at the connector part can be timely perceived.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, and relates to the waterproofing of prefabricated subway station joints, in particular to a prefabricated assembled subway station tongue-and-groove joint capable of monitoring water leakage. Background technique [0002] With the development of China's underground engineering, subway transportation has gradually become the main mode of urban personnel transportation. As the transit section of the subway system, the construction method and monitoring measures of the subway station are being paid more and more attention by people. Prefabricated subway station is an emerging construction method of subway station, which optimizes the construction method of the original subway station structure pouring on site, and uses prefabricated assembly components, which greatly improves the construction speed and construction quality of the subway station. However, because the station structur...

AI Technical Summary

Problems solved by technology

However, because the station structure of the prefabricated subway station adopts an assembled design, there are tongue-and-groove joints, and the waterproof performance of the joints is poor. Therefore, it is necessary to carry out anti-seepage treatment on the joints and conduct timely and effective monitoring in order to maintain the safety of the station and stable
