Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel crack seepage detection equipment, and in particular relates to a multi-channel pressure sensing conduit for detecting seepage in tunnel secondary lining cracks. Background Technology

[0002] Tunnel secondary lining refers to the construction process of adding a second lining to the inner wall of the tunnel after the initial lining is completed, in order to protect the inner wall and ensure the stability of the tunnel structure. Tunnel secondary lining typically uses materials such as concrete or reinforced concrete to improve the tunnel's load-bearing capacity and waterproofing performance. During tunnel construction, it is necessary to detect the seepage pressure in the secondary lining cracks to better ensure the tunnel's stability and safety. Existing technologies often use seepage pressure sensors in conjunction with multi-channel pressure sensor conduits for detection. However, existing pressure sensor conduits can only transmit data signals and cannot provide feedback to construction personnel inside the poorly lit tunnel. Therefore, we propose a multi-channel pressure sensor conduit for detecting seepage in tunnel secondary lining cracks. Utility Model Content

A support partition is fixed inside the control box, and a controller is fixedly mounted on the top of the support partition. The seepage pressure sensor is electrically connected to the controller via the transmission wire. A wireless transmitter is fixedly mounted on the top of the inner side of the control box, and an alarm is fixedly mounted on the top of the control box. A battery holder is fixedly connected to the bottom of the inner side of the control box, and a storage battery is inserted inside the battery holder.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0020] A multi-channel pressure sensing conduit for detecting water seepage in tunnel secondary lining cracks includes a seepage pressure sensor 1. The seepage pressure sensor 1 is connected to a control box 3 fixed on the inner wall of the tunnel secondary lining via a transmission conduit 2. A transmission wire 21 and warning light strips 22 are fixed inside the transmission conduit 2. Three warning light strips 22 are provided inside the transmission conduit 2, each capable of emitting red, yellow, and green light respectively. All three warning light strips 22 are preferably energy-saving LED strips, and can display red, yellow, and green light sequentially according to the pressure from highest to lowest. A support partition 31 is fixedly installed inside the control box 3, and a controller 4 is fixedly mounted on the top of the support partition 31. The seepage pressure sensor 1 is electrically connected to the controller 4 via the transmission wire 21. A control box 4 is fixedly mounted on the top of the inner side of the control box 3. A wireless transmitter 5 is provided, which works in conjunction with an external wireless receiver to wirelessly transmit the crack seepage pressure information received by the controller 4 to an external computer. This allows engineering technicians to remotely monitor and view the seepage situation at the cracks. An alarm 6 is fixedly installed on the top of the control box 3. The warning light strip 22, the wireless transmitter 5, and the alarm 6 are electrically connected to the controller 4 via wires. A battery holder 7 is fixedly connected to the bottom inside the control box 3, and a storage battery 8 is inserted inside the battery holder 7. By setting the warning light strip 22 inside the transmission conduit 2, the actual monitored crack seepage pressure can be used to better provide safety feedback and reminders to construction personnel in poor lighting conditions inside the tunnel, and can also help workers quickly find the seepage location.

[0021] Battery slots 71 are arranged side by side on the front of the battery holder 7, and each battery slot 71 is used to insert a battery 8. The replacement of the battery 8 is done using the same technology as the replacement of existing movable batteries, which will not be described in detail here. When replacing two batteries 8, one battery 8 can be replaced before the other battery 8 is replaced, thus achieving continuous power supply to the device. The two batteries 8 are electrically connected to the controller 4 through wires provided inside the battery holder 7. The battery slots 71 are opened at an angle, and the front of the battery slots 71 is higher than the rear of the battery slots 71. The battery 8 can provide power to the detection device without the need for external wiring, making the installation more convenient. The two batteries 8 provide continuous power to the detection device, thereby enabling continuous detection of water seepage in tunnel secondary lining cracks.

[0022] Working principle: In use, the seepage pressure sensor 1 can be fixed at a suitable location at the crack in the tunnel lining, and the control box 3 can be fixed on the inner wall of the tunnel lining. The seepage pressure sensor 1 can detect the seepage pressure in the tunnel lining crack and convert the pressure signal into an electrical signal, which is transmitted to the controller 4 through the transmission wire 21. The controller 4 can analyze and process the received signal and then wirelessly transmit it to an external computer through the wireless transmitter 5. Construction technicians can monitor and view the seepage situation in the crack through the external computer. According to the detected pressure, the controller 4 can activate the three warning light strips 22 respectively. The power supply is used to assist tunnel workers in understanding the water seepage situation through the specific color of the warning light strip 22. When the pressure of the water seepage detection exceeds the safety set value, the controller 4 can control the alarm 6 to be powered on to issue an alarm, reminding the tunnel workers to leave the danger zone in time. During the detection process, the detection device is powered by the battery 8. When the battery 8 needs to be replaced, one side of the battery 8 can be removed and replaced first, and then the other side of the battery 8 can be removed and replaced. This can achieve continuous power supply to the detection device, thereby achieving continuous detection of the water seepage pressure of the tunnel secondary lining cracks.
