Description

Technical Field

[0001] The invention belongs to the field of bridge engineering, and in particular relates to a water seepage detection device for bridge construction. Background Art

[0002] Bridge water seepage detection is an important part of bridge engineering maintenance and management, which aims to identify and evaluate the water penetration inside the bridge structure. Through regular inspection, water seepage problems can be detected early to prevent moisture from causing long-term damage to the bridge structure. Detection methods include visual inspection and instrument detection. Professionals can find surface cracks or traces of water seepage through visual inspection, or use high-tech equipment such as infrared thermal imagers and ultrasonic detectors to find the location and extent of water seepage. In addition, water level gauges are set under or around the bridge to monitor water level changes to determine the source of water seepage. The material, design, construction quality and environmental factors (such as rainfall, freezing, etc.) of the bridge will affect the water seepage. For the detected problems, detailed analysis is required, and corresponding reinforcement or repair plans are formulated to ensure the safety and service life of the bridge. In short, bridge water seepage detection not only helps to protect the bridge structure, but also ensures traffic safety and extends the service life of the bridge.

[0003] Currently, when conducting bridge seepage detection, after the instrument is installed on the bridge, the air in the instrument needs to be manually exhausted and then the instrument needs to be sealed to ensure the sealing effect between the instrument and the bridge surface. This method requires a lot of manual operation, and water will flow out during the process of exhausting the air, making it difficult to observe whether the instrument and the bridge are perfectly sealed.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1 As shown, in an embodiment of the present invention, a bridge construction water seepage detection device comprises: a support platform 1, a measuring cylinder 2 is arranged on the support platform 1, a guide tube 3 is arranged on one side of the measuring cylinder 2 passing through the support platform 1, and an opening and closing handle 4 is arranged on the guide tube 3. The bridge construction water seepage detection device comprises: A closed chamber 5 is connected to one end of the conduit 3, and the closed chamber 5 is connected to the support 1 via a plurality of pillars 6, and one end of the conduit 3 extends into the closed chamber 5; A sealed collar 7, mounted at the bottom of the closed chamber 5; The adaptive exhaust component 8 is arranged on the closed chamber 5 and is connected to the interior of the closed chamber 5. The adaptive exhaust component 8 is used to discharge the air inside the closed chamber 5 when the water in the measuring cylinder 2 enters the closed chamber 5, and to seal the closed chamber 5 when there is no residual air in the closed chamber 5.

[0018] When the bridge construction water seepage detection device is used, first mark the points on the bridge, then lay the sealing material around the points, and then place the device on the sealing material, so that the closed ring 7 at the bottom of the closed chamber 5 is in contact with the sealing material, and press hard until the sealing material is completely fitted; Water is injected into the measuring cylinder 2 until the water level reaches the highest scale line of the measuring cylinder 2, and then the opening and closing handle 4 is opened to allow the water in the measuring cylinder 2 to flow into the closed chamber 5, and the sealing condition is observed to be good. If there is a water leak, the sealing operation is performed again. If the sealing is good, the air in the closed chamber 5 will be discharged through the adaptive exhaust component 8 during the process of water flowing into the measuring cylinder 2, and when all the air is discharged, the adaptive exhaust component 8 will be automatically closed to prevent the water from flowing out of the adaptive exhaust component 8. This process is fully automated and does not require manual processing. The automation effect is better and the situation of misjudgment of the sealing due to the outflow of water can also be avoided. Then, add the water in the measuring cylinder 2 to the highest scale line, and then observe the change of the water level within a certain period of time to determine the water seepage. Example

[0019] like Figures 2 to 5As shown, in an embodiment of the present invention, the adaptive exhaust component 8 includes: A branch pipe 9 is connected to one side of the closed chamber 5, and the branch pipe 9 is communicated with the inside of the closed chamber 5; A first baffle 10 is disposed at one end of the branch pipe 9 communicating with the closed chamber 5, and a plurality of ventilation mesh holes 11 are formed on the first baffle 10; A connecting air guide column 12 is provided at one end of the branch pipe 9, and a side of the connecting air guide column 12 is connected to the branch pipe 9, and an air outlet 13 is provided at the top of the connecting air guide column 12; The blocking block 14 is disposed inside the connecting air guide column 12 , and the density of the blocking block 14 is less than the density of water. The blocking block 14 is used to cooperate with the air outlet 13 to seal the connecting air guide column 12 .

[0020] During use, when the opening and closing handle 4 is opened to allow water to flow into the closed chamber 5, the air in the closed chamber 5 will flow into the connecting air guide column 12 through the branch pipe 9 and be finally discharged through the air outlet 13. When all the air is discharged, since the branch pipe 9 is located at the upper position of the closed chamber 5, water will eventually flow into the branch pipe 9 and be introduced into the connecting air guide column 12 through the branch pipe 9. Since the density of the blocking block 14 is less than the density of water, under the action of the buoyancy of water, the blocking block 14 will gradually rise until the blocking block 14 contacts the air outlet 13 and blocks the air outlet 13, thereby achieving the airtight effect of the closed chamber 5.

[0021] like Figures 2 to 5 As shown, in the embodiment of the present invention, a second baffle 15 is provided at the connection between the branch pipe 9 and the connecting air guide column 12 , and a plurality of air outlet holes 16 are opened on the second baffle 15 .

[0022] By providing the second baffle 15 , it can be ensured that the blocking block 14 will not enter the branch pipe 9 during the floating process, and it can be ensured that the blocking block 14 can float normally and contact the air outlet 13 .

[0023] like Figures 2 to 4 As shown, in the embodiment of the present invention, a sealing pad 17 is further provided on the blocking block 14 , and the sealing pad 17 cooperates with the air outlet 13 .

[0024] By providing the sealing pad 17 , the contact between the blocking block 14 and the air outlet 13 can be made closer, thereby ensuring the stability of the sealing effect. Example

[0025] like Figure 6 to Figure 7 As shown, in an embodiment of the present invention, the adaptive exhaust component 8 includes: A hollow column 18 is disposed on the closed chamber 5, and the hollow column 18 is communicated with the closed chamber 5; A third baffle 19 is provided at the connection between the hollow column 18 and the closed chamber 5. A plurality of drainage holes 20 are provided on the third baffle 19. A gas guide port 21 is provided at the top of the hollow column 18. The blocking ball 22 is disposed inside the hollow column 18 , and the density of the blocking ball 22 is less than the density of water.

[0026] During use, when the opening and closing handle 4 is opened to allow water to flow into the closed chamber 5, the air in the closed chamber 5 will pass through the hollow column 18 and be discharged through the air guide port 21. When all the air is discharged, the water will enter the hollow column 18 through the drainage hole 20. Since the density of the sealing ball 22 is less than the density of water, under the action of the buoyancy of water, the sealing ball 22 will gradually rise until the sealing ball 22 contacts the air guide port 21 and seals the air guide port 21, thereby achieving the airtight effect of the closed chamber 5.

[0027] like Figures 5 and 6 As shown, in the embodiment of the present invention, a sealing gasket 23 is provided on the inner wall of the air guide port 21 , and the sealing gasket 23 cooperates with the blocking ball 22 .

[0028] By providing the sealing gasket 23 , the contact between the blocking ball 22 and the air guide port 21 can be made closer, thereby ensuring the stability of the sealing effect.

[0029] In the embodiment of the present invention, the outer diameter of the blocking ball 22 is greater than the inner diameter of the air guide port 21 .

[0030] In summary, when the bridge construction water seepage detection device is used, first mark the points on the bridge, then lay the sealing material around the points, and then place the device on the sealing material, so that the closed ring 7 at the bottom of the closed chamber 5 is in contact with the sealing material, and press hard until the sealing material is completely fitted; Water is injected into the measuring cylinder 2 until the water level reaches the highest scale line of the measuring cylinder 2, and then the opening and closing handle 4 is opened to allow the water in the measuring cylinder 2 to flow into the closed chamber 5, and the sealing condition is observed to be good. If there is a water leak, the sealing operation is performed again. If the sealing is good, the air in the closed chamber 5 will be discharged through the adaptive exhaust component 8 during the process of water flowing into the measuring cylinder 2, and when all the air is discharged, the adaptive exhaust component 8 will be automatically closed to prevent the water from flowing out of the adaptive exhaust component 8. This process is fully automated and does not require manual processing. The automation effect is better and the situation of misjudgment of the sealing due to the outflow of water can also be avoided. Then, add the water in the measuring cylinder 2 to the highest scale line, and then observe the change of the water level within a certain period of time to determine the water seepage.
