Description

Technical Field

[0001] This application relates to the field of waterproof testing technology, specifically a device for testing the construction quality of tunnel waterproof layers. Background Technology

[0002] With the rapid development of national highway construction, especially as highways extend into mountainous areas or encounter lakes and rivers, a large number of tunnel projects have been constructed. However, various types and degrees of pathological disasters have occurred during the operation of tunnel projects, among which tunnel leakage is the most common, especially in undersea tunnels or in cold seasons, where it can also cause frost damage, directly affecting the normal use and safety of the tunnel structure.

[0003] An existing patent (publication number: CN209559423U) discloses a tunnel waterproofing layer construction quality testing device, including a testing cover, a hose, and an air pump. An air outlet pipe is provided on the outer wall of the testing cover, and the air outlet pipe is connected to the air pump via the hose. In this invention, a testing liquid (soapy water) is applied to the area to be tested. The testing cover is held by hand and placed on the testing area. Then, the air pump is turned on to draw air from inside the testing cover, bringing the internal pressure to -0.05 MPa. The presence of air bubbles in the testing liquid indicates the sealing performance of the waterproofing layer. This tunnel waterproofing layer construction quality testing device has a simple structure and is easy to operate. During testing, the testing cover can be clipped into different positions to perform sealing tests on the waterproofing layer and its welded joints. It is highly practical. Furthermore, this tunnel waterproofing layer construction quality testing device can be used to test whether the waterproofing layer is installed inside the tunnel or not, further improving its practicality.

[0004] The above-mentioned detection cover requires soapy water to be prepared and manually applied to the detection area during use, which is a cumbersome process. In addition, carrying and storing the soapy water also requires additional containers and equipment, which increases the complexity of the detection work. Furthermore, the operation of applying soapy water will take up some time and reduce the detection efficiency, especially in emergency situations where it is necessary to quickly locate the leak.

The suction pipe 4 is fixedly embedded in the inspection cover 1. A piston rod 5 is slidably inserted inside the suction cylinder 2. With the above configuration, soapy water can be automatically sprayed when the inspection cover 1 is placed. One-way valves 6 are installed inside both the suction pipe 4 and the liquid outlet pipe 3. When the piston rod 5 moves upward, the one-way valve 6 in the suction pipe 4 is in the open state and the one-way valve 6 in the liquid outlet pipe 3 is in the closed state. When the piston rod 5 moves downward, the one-way valve in the suction pipe 4 is in the closed state and the one-way valve in the liquid outlet pipe 3 is in the open state.

[0033] Please see Figure 1 , Figure 2 and Figure 4A handle 11 is fixedly connected to the top of the piston rod 5. The handle 11 makes it easy for the user to press down the piston rod 5. Two symmetrically arranged reset cylinders 12 are fixedly embedded in the top of the detection cover 1. A reset rod 13 is slidably inserted into the interior of each reset cylinder 12. The top of each reset rod 13 is fixedly connected to the bottom of the handle 11. A spring 14 is fixedly connected to the bottom of the reset cylinder 12 adjacent to the bottom of each reset rod 13. The spring 14 enables the automatic reset of the handle 11 and the piston rod 5.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The top end of the suction tube 4 is fixedly connected to a connector 7, and the top end of the connector 7 is threadedly connected to a storage tube 8. The top end of the storage tube 8 is rotatably connected to a stirring shaft 9. Multiple stirring blades 10 are fixedly connected to the outer surface of the stirring shaft 9. Through the arrangement of the stirring blades 10 and the stirring shaft 9, the soap water can be mixed evenly and the static stratification can be avoided. The top end of the stirring shaft 9 is fixedly connected to a turntable 18. Through the arrangement of the turntable 18, it is easy for the user to rotate the stirring shaft 9.

[0035] Please see Figure 1 , Figure 2 and Figure 3 A sealing gasket 15 is fixedly connected to the bottom of the detection cover 1. The sealing gasket 15 can improve the airtightness of the detection cover 1. A pressure sensor 16 is fixedly installed at the top of the detection cover 1. The pressure sensor 16 can monitor the pressure inside the detection cover 1. A connecting pipe 17 is fixedly connected to the top of the detection cover 1. The connecting pipe 17 can facilitate the user to connect with the external pump body.

[0036] This embodiment of a tunnel waterproofing layer construction quality inspection device, through the designed structure of suction cylinder 2, suction pipe 4, and discharge pipe 3, combined with the sliding operation of piston rod 5, realizes the function of automatically spraying soapy water when placing the inspection cover 1, eliminating the tedious step of manually applying soapy water and significantly improving inspection efficiency. The design of reset cylinder 12 and spring 14 realizes the automatic reset function of piston rod 5 and handle 11, making operation simpler and faster. The device is equipped with stirring shaft 9 and stirring blade 10. By rotating stirring shaft 9, the soapy water can be ensured to be evenly mixed in storage pipe 8, avoiding the stratification phenomenon that may be caused by long-term standing, avoiding affecting the user's observation of the situation, and improving the inspection accuracy. The sealing gasket 15 at the bottom of the inspection cover 1 is designed to enhance airtightness and ensure the stability of internal pressure during the inspection process, while the setting of pressure sensor 16 can monitor the pressure changes inside the inspection cover 1 in real time. This device integrates multiple functions such as soapy water storage, mixing, spraying, and pressure detection into one unit, without the need for additional containers and equipment, significantly simplifying the inspection process and reducing inspection costs.

[0037] The working principle of the above embodiment is as follows: First, the user injects soapy water into the storage tube 8 and rotates the turntable 18 on the stirring shaft 9 to drive the stirring blade 10 to rotate inside the storage tube 8, ensuring that the soapy water is mixed evenly and avoiding stratification caused by prolonged standing. Next, the user places the detection cover 1 on the waterproof layer to be tested. At this time, the sealing gasket 15 at the bottom of the detection cover 1 is in close contact with the waterproof layer, forming a good sealing effect. This design enhances the airtightness during the testing process and ensures the stability of the internal pressure. Then, the user presses down the handle 11 on the piston rod 5 to make the piston rod 5 slide inside the suction cylinder 2, spraying the soapy water onto the testing surface through the liquid outlet pipe 3. After spraying the soapy water, the user... The external pump body is connected to the detection cover 1 through the connecting pipe 17. The pump body is started to draw air out of the detection cover 1, so that the internal pressure gradually decreases. At this time, the pressure sensor 16 monitors the pressure change inside the detection cover 1 in real time and feeds the data back to the user. If there is a leak in the waterproof layer, soapy water will seep into the leak under negative pressure and generate bubbles. The user can judge the sealing of the waterproof layer by observing the position and number of bubbles. Finally, after the test is completed, the user releases the handle 11 on the piston rod 5. Due to the design of the reset cylinder 12 and the spring 14, the piston rod 5 and the handle 11 will automatically return to the initial position. The suction cylinder 2 sucks in the soapy water through the suction tube 4 to prepare for the next use.
