Description

Technical Field

[0001] The utility model specifically relates to a road bridge water seepage detection device, belonging to the technical field of water seepage detection. Background Art

[0002] Bridge seepage refers to the phenomenon of water leakage due to holes in the bridge structure. Long-term bridge seepage problems will not only cause damage to the bridge structure, but also affect the safety of surrounding traffic. Therefore, the detection and treatment of bridge seepage problems are crucial. After the completion of the bridge, it is often necessary to conduct a seepage test, which is generally carried out using a seepage meter. The seepage meter usually includes a base and a measuring cylinder installed on the base. During the detection process, the staff needs to observe and record the changes in the water level line of the measuring cylinder at regular intervals. A total of three observations and records are required, and the seepage rate is calculated. Existing seepage detection devices such as China Patent Publication No.: CN118777165A discloses a road bridge seepage detection device, which uses the water in the first storage chamber to cool it down, and then judges it through the temperature control display. When the ground temperature reaches the standard value, it uses the second storage chamber to accurately test it. Detection, when facing road surfaces with different temperatures, the road surface can be cooled down first, and then the detection can be carried out to achieve the effect of accurate numerical values; the cooling process of the above-mentioned structure is relatively cumbersome, and it is impossible to ensure that the device and the road bridge are fully sealed; in addition, the contact surface between the existing water seepage detection device and the road bridge cannot monitor whether it is sealed in place; it can only determine the failure of the seal by the rapid reduction of the water volume inside the metering cylinder, but for local inadequate sealing, resulting in a small amount of infiltration, it cannot be directly detected, so that the infiltration amount is easily superimposed on the water seepage rate of the road bridge, and the detection accuracy cannot be guaranteed; and when infiltration occurs, the detection point needs to be replaced, and the operation is relatively cumbersome. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a road bridge water seepage detection device, which can facilitate the full sealing of the road bridge detection position. After sealing, the contact surface can be cooled simultaneously through the emptying operation.

[0009] A pressure-sealing force-applying unit, the pressure-sealing force-applying unit comprises a sleeve that is slidably matched with the threaded pipe section; the bottom of the sleeve is pressed against the top surface of the outer ring seat; a locking sleeve is screwed onto the outside of the threaded pipe section; a plurality of hinged seats are fixed to the outside of the sleeve, a clamping seat is fixed to the lower part of the hinged seat; a support rod is hinged on the hinged seat, a bayonet that is integrally formed on the support rod and is clamped with the clamping seat; the bottom of the support rod abuts against the top surface of the outer ring seat;

[0011] The metering tube is hollow at both ends, the bottom of the metering tube is screwed to the top surface of the tube seat, and a second switch valve is fixed on the top of the metering tube.

[0012] Before water seepage detection, place the positioning plate at the detection point, then screw and fix the liquid storage tank and the transition pipe, then clamp the detection seat body to the inside of the positioning plate, and clamp the counterweight block to the outside of the outer partition seat; the counterweight block is a U-shaped structure, and there are multiple pieces, which are stacked on the positioning plate from bottom to top. When adjacent counterweight blocks are installed, the openings face opposite directions; after the counterweight block and the detection seat body are installed, rotate the locking sleeve, drive the sleeve to push down through the locking sleeve, and the sleeve applies force to the outer ring seat through the support rod. The outer ring seat drives the inner ring seat downward through the sliding column, and the inner ring seat drives The elastic seal is pressed downward to achieve compression between the elastic seal and the detection position; the travel of the locking sleeve can be shortened by swinging the support rod; when detecting water seepage, first open the first switch valve and the second switch valve, and the liquid inside the liquid storage tank is pumped into the inside of the pipe seat, then the detection position can be cooled, and at the same time, the air inside the liquid storage tank is discharged through the second switch valve. When the liquid in the metering tube is discharged from the second switch valve, close the first switch valve and the second switch valve, then observe the liquid level scale on the metering tube, and record and calculate the water seepage rate by regularly observing the changes in the water level line.

[0013] Furthermore, the elastic pressure seal is integrally formed with an annular groove on the bottom surface, and an air pipe is embedded on the top surface of the annular groove, and the air pipe is connected to the pipe joint on the outer partition seat through a hose; the pipe joint is connected to the third switch valve through a pressure transmitter, and the third switch valve is connected to the inflation device or the vacuum device; during operation, the inflation device or the vacuum device is connected to the third switch valve, and the third switch valve is opened. At this time, when the inflation device or the vacuum device reaches the set value, the third switch valve is closed, and the real-time pressure is continuously monitored within the set time through the pressure transmitter. When the pressure remains above the set pressure value, the seal is passed, otherwise the seal fails, and the pressure seal force unit needs to be operated to achieve re-force sealing. After the adjustment is completed, the above operation is performed again until the seal is passed. When the seal fails multiple times, the road and bridge detection point needs to be replaced; after the seal is passed, water can be injected for water seepage detection.

When the detection seat body is installed in place, the top block is separated from the outer ring seat. At this time, the outer ring seat can be pushed down, thereby realizing the compaction seal between the elastic pressure seal and the road bridge.

[0016] Furthermore, a rotating handle is fixed to the outside of the locking sleeve, and the locking sleeve can be easily operated by rotating the handle to achieve the locking sleeve rotating downward or rotating upward and retreating.

[0017] Furthermore, the outer edge bottom surface and top surface of the outer ring seat are integrally formed into a limiting ring; through the limitation of the limiting ring, the bottom of the support rod and the top of the top block can be limited.

The operation is simple and convenient. During the installation of the detection seat body and the positioning plate, the elastic pressure seal will never contact the surface of the road and bridge. Then, the counterweight block and the liquid storage tank are used to counterweight the detection seat body to be stably pressed on the surface of the road and bridge. Then, the pressure seal force applying unit applies force to the elastic pressure seal, so that the bottom surface of the elastic pressure seal is tightly pressed against the top surface of the road and bridge. It can facilitate the full sealing of the contact surface between the outside of the pipe seat and the road and bridge. After sealing, the contact surface can be cooled synchronously by the emptying operation. In addition, the sealing effect of the detection position can be tested, which can prevent the replacement of the detection position after the seal fails, and can ensure the accuracy of water seepage rate detection.
