Problems solved by technology

[0002] The subway has become an indispensable means of transportation in daily traffic travel. When excavating subway tunnels, water leakage is usually encountered in the tunnel. If the water leakage cannot be repaired in time, it may affect the soil quality, cause ground collapse, and affect the quality of the foundation. support, resulting in a safety accident
However, the currently used equipment can only detect water leakage points during use, and cannot temporarily store water, and the equipment only reminds workers through warning lights. When encountering poor sightlines or tunnel corners, it is difficult for workers to find the location of the warning lights. hint, so it is necessary to improve

Abstract

The invention discloses an intelligent detection system and method for detecting water leakage of a rail transit running tunnel, and belongs to the field of tunnel water leakage detection equipment. The system comprises a collecting pipe, a movable device and a control device; the movable device is arranged on the collecting pipe, and the control device is arranged between the collecting pipe and the movable device; the collecting pipe comprises an L-shaped water pipe and a vertical plate; and the section of the L-shaped water pipe is rectangular, a through hole is formed in the upper portion of the horizontal end of the L-shaped water pipe, the vertical plate is fixedly connected to the upper end of an end opening of the horizontal end of the L-shaped water pipe, and a sliding groove I is formed in the side, away from the vertical end of the L-shaped water pipe, of the vertical plate. When the system and method are used, a water column in a rectangular cylinder can be always kept at a high position, a worker can conveniently observe water leakage; the gap between the rectangular cylinder and the vertical plate can be expanded along with the increase of water quantity, so that temporary water storage is facilitated; and a warning signal can be sent out through knocking and water drop sound, so that the worker can conveniently judge whether water leakage exists or not.
