Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tunnel structure monitoring, and particularly relates to a structure inner wall leakage water detection device. BACKGROUND

[0002] Tunnel leakage water is the most common form of tunnel disease, which not only may cause tunnel erosion and damage, endangering the durability of the tunnel structure, but also may affect driving safety and tunnel aesthetics.

[0003] The initial tunnel leakage water is found by artificial patrol to find the tunnel leakage water, which cannot find the leakage in time.

[0004] A tunnel leakage detection device is disclosed in Chinese patent literature CN112304510B, which is installed on the inner wall of the tunnel. When the tunnel leaks, water will flow along the inner wall of the tunnel to the upper surface of the installation box and accumulate on the plastic film. The accumulated plastic film will drop, the needle will pierce the plastic film, and the water will flow into the installation box, so that the color of the anhydrous copper sulfate in the installation box changes from white to blue. The device also needs to be checked regularly, and the leakage can only be found during the inspection process. The leakage cannot be found in time.

[0005] A city tunnel side wall leakage automatic monitoring equipment is disclosed in Chinese utility model patent literature CN216976435U, which uses an infrared thermal imaging camera to identify tunnel leakage.

[0030] As shown in the drawings, the structure inner wall leakage water detection device comprises a leakage water collection assembly 1, a leakage water collection electromagnetic valve 3, a leakage water identification assembly 2, a conveying pump 4 and a control assembly 6. The leakage water collection assembly 1 is sequentially arranged on the tunnel side wall along the tunnel extension direction. The leakage water collection assembly 1 has a water collecting tank 11. A flow guide wedge-shaped plate 111 is fixedly arranged on the top of one side of the water collecting tank 11 close to the tunnel side wall. A partition plate 12 is arranged in the water collecting tank 11. The partition plate 12 is integrally welded with the inside of the water collecting tank 11. The partition plate 12 divides the inside of the water collecting tank 11 into a water collecting cavity 113. A drain pipe joint 17 is arranged on the bottom of the water collecting cavity 113 and is connected with the inside of the water collecting cavity 113. Figures 1 to 9 The leakage water identification assembly 2 has a detection bin 21. An installation side plate 24 is fixedly arranged on one side of the detection bin 21. An input pipe 23 and an output pipe 22 are arranged on the top of the detection bin 21. A water immersion sensor 26 is arranged on the inner bottom of the detection bin 21. The drain pipe joint 17 is connected with one end of the leakage water collection electromagnetic valve 3 through a pipeline. The other end of the leakage water collection electromagnetic valve 3 is connected with the input pipe 23. The conveying pump 4 is connected with the output pipe 22 through a pipeline. The control assembly 6 has a control module 61. A communication module 62 is connected with the control module 61 and is in communication connection with a monitoring center 7. The water immersion sensor 26 and the leakage water collection electromagnetic valve 3 are connected with the control module 61.

[0031] In the above embodiment, the plurality of leakage water collection assemblies 1 arranged in sequence along the tunnel side wall are respectively connected with the input pipe 23 of the leakage water identification assembly 2 through a leakage water collection electromagnetic valve 3. The leakage water collection electromagnetic valve 3 remains in a closed state, and a delivery pump 4 is periodically started for a period of time to monitor the leakage water condition. During this period of time, the leakage water collection electromagnetic valve 3 is sequentially turned on for a period of time and then turned off in sequence, and each time one leakage water collection electromagnetic valve 3 remains in an on state. When the tunnel side wall corresponding to the leakage water collection assembly 1 leaks, the leakage water flows into the water collecting cavity 113 inside the water collecting groove 11. When the leakage water collection electromagnetic valve 3 corresponding to the water collecting cavity 113 is turned on, the leakage water is pumped by the delivery pump 4 to the inside of the detection bin 21. The leakage water collects at the bottom of the detection bin 21, and the water immersion sensor 26 is immersed in the leakage water, triggering the water immersion sensor 26.

The monitoring center 7 can timely find the leakage. The leakage water is detected by the water immersion sensor 26, which is less affected by the external environment temperature and ensures the accuracy of the monitoring. When the leakage occurs, the leakage water collection electromagnetic valve 3 remains in an on state, and the delivery pump 4 continuously runs, which can continuously pump the leakage water in the leakage water collection assembly 1 into the detection bin 21 and then from the detection bin 21 to the sewer or other designated place for discharge or collection, avoiding the overflow of the leakage water in the leakage water collection assembly 1 and flowing into the tunnel, thereby limiting the influence range of the leakage water.
