Description

Technical Field

[0001] This utility model relates to the field of building construction testing technology, specifically a water seepage detection device for highway bridge pavement. Background Technology

[0002] Water seepage detection on highway bridge pavements is a crucial step in ensuring bridge structural safety. Water seepage can lead to problems such as steel reinforcement corrosion and concrete deterioration, ultimately affecting the bridge's safety and lifespan. Therefore, regular water seepage detection and timely repair are essential.

[0003] When conducting water seepage detection on asphalt-based highway bridges, water needs to flow onto the asphalt pavement. During water seepage, the time it takes for the water to fall needs to be observed in a timely manner. However, the water level in the entire seepage detection device drops continuously as the water falls, making it difficult for inspectors to observe the water level in a timely manner, which may lead to inaccurate measurement results. Therefore, we propose a water seepage detection device for highway bridge pavements. Utility Model Content

[0004] The purpose of this invention is to provide a water seepage detection device for highway bridge pavement to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water seepage detection device for highway bridge pavement, comprising a water supply mechanism, a counterweight, and an air release valve. The water supply mechanism is disposed on the pavement to be tested. A water-holding cylinder for testing water load is fixedly installed on the top of the water supply mechanism. A counterweight is fixedly installed on the water supply mechanism. An air release valve is provided through the top of the water supply mechanism. A lifting mechanism that contacts the top of the water-holding cylinder is slidably connected inside the water-holding cylinder. An indicator mechanism for easy observation of the water drop speed is provided on the top of the water supply mechanism.

[0006] Furthermore, the water supply mechanism includes a fixed base, a drainage trough, a through hole, a drain valve, a connecting pipe, and a top plate. The top of the fixed base is fixedly connected to the top plate by multiple sets of connecting columns. The bottom of the fixed base has a drainage trough. The fixed base has a through hole. A connecting pipe is provided between the top plate and the fixed base to connect the water tank and the through hole. A drain valve is provided on the connecting pipe.

[0007] Furthermore, the lifting mechanism includes a limiting post, a sliding sleeve, a float block, a column, and an indicator rod.

[0010] Furthermore, multiple sets of drainage channels are provided on the outside of the water-holding cylinder.

[0011] Compared with the prior art, the present invention has the following advantages: The water supply mechanism of the present invention is placed on the asphalt pavement to be tested, and a sealing filler is set between the water supply mechanism and the ground.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a water seepage detection device for highway bridge pavement, including a water supply mechanism 1, a counterweight 2, and an air release valve 6. The water supply mechanism 1 is set on the test pavement. A water-holding cylinder 3 for testing water load is fixedly installed on the top of the water supply mechanism 1. The counterweight 2 is fixedly installed on the water supply mechanism 1. An air release valve 6 is provided through the top of the water supply mechanism 1. A lifting mechanism 4 that contacts the top of the test water is slidably connected inside the water-holding cylinder 3. An marking mechanism 5 is provided on the top of the water supply mechanism 1 to facilitate the observation of the water drop speed.

[0020] The water supply mechanism 1 is placed on the asphalt pavement to be tested, and a sealing filler is installed between the water supply mechanism 1 and the ground. The counterweight 2 ensures that the water supply mechanism 1 is in full contact with the sealing filler. Then, the water supply mechanism 1 is turned on to supply water, and the air at the bottom of the water supply mechanism 1 can be discharged through the air release valve 6. After the water is discharged through the air release valve 6, the air release valve 6 is sealed. Then, the water tank 3 is filled. After the water falls, the lifting mechanism 4 will fall with it. In this way, the user can observe the water position on the higher marking mechanism 5 based on the lifting mechanism 4. This detection device is more convenient for detecting water seepage and the detection is more accurate.

[0021] Please see Figure 1 , Figure 2 and Figure 5 The water supply mechanism 1 includes a fixed base 7, a drainage trough 8, a through hole 9, a drain valve 10, a connecting pipe 11, and a top plate 13. The top of the fixed base 7 is fixedly connected to the top plate 13 by multiple sets of connecting columns 12. The bottom of the fixed base 7 is provided with a drainage trough 8. The fixed base 7 is provided with a through hole 9. A connecting pipe 11 is provided between the top plate 13 and the fixed base 7 to connect the water tank 3 and the through hole 9. A drain valve 10 is provided on the connecting pipe 11.

[0022] When it is necessary to lower the water tank 3 into the water, the drain valve 10 is opened, allowing the test water inside the water tank 3 to fall through the connecting pipe 11 and the through hole 9, so that the test water can fall down for testing.

[0023] Please see Figure 1 , Figure 2, Figure 3 and Figure 5 The lifting mechanism 4 includes a limiting post 14, a sliding sleeve 15, a float block 16, a column 17, and an indicator rod 18. Two sets of limiting posts 14 are fixedly installed inside the water tank 3. The float block 16 is slidably connected to the outside of the limiting post 14 through the sliding sleeve 15. The column 17 is fixedly connected to the top of the float block 16. The indicator rod 18 is fixedly connected to one side of the column 17. The marking mechanism 5 includes a connecting rod 19 and an indicator plate 20. Two sets of connecting rods 19 are fixedly installed on the top of the top plate 13. The indicator plate 20 is fixedly connected to the top of the connecting rod 19.

[0024] When the drain valve 10 is opened, the water inside the water tank 3 falls down. Then the float block 16 and the sliding sleeve 15 will fall along the limit post 14. At this time, the falling float block 16 can drive the column 17 and the indicator rod 18 to fall down. Then the indicator rod 18 can be aligned with the corresponding indicator on the indicator plate 20. At this time, the operator can observe the falling speed of the water inside the water tank 3 from a higher position, which is convenient for accurate calculation of the road surface seepage performance.

[0025] The precise calculation method for pavement permeability is as follows:

[0026] Permeability coefficient = (V2 - V1) / (t2 - t1)

[0027] in:

[0028] V2, V1: The amount of water remaining in the water tank at times t2 and t1 (which can be calculated from the water level).

[0029] t2, t1: Observation time points.

[0030] Time (t): Use a stopwatch to record the time from when the drain valve is opened.

[0031] Water volume (V) or water level (h): The water level is read by the position of the indicator rod on the indicator plate. Since the cross-sectional area of ​​the water tank is fixed, the water level can be converted into water volume.

[0032] For example:

[0033] t1=0min, indicator rod 18 is in the full water state at the 50cm mark;

[0034] t2 = 2 min, indicator 18 is at the 40 cm mark;

[0035] At this time, the cross-sectional area of ​​water cylinder 3 is 100cm²;

[0036] Therefore, the seepage volume = (50-40)×100 = 1000mL;

[0037] Therefore, the permeability coefficient = 1000 mL / 2 min = 500 mL / min;

[0038] Therefore, the larger the calculated permeability coefficient, the faster the road surface seeps water, which means that the asphalt density is insufficient or there are cracks.

[0039] Please see Figure 3 and Figure 4 The float block 16 is shaped like a frustum, and the inner wall of the sliding sleeve 15 is rotatably connected to multiple sets of ball bearings 22. The multiple sets of ball bearings 22 on the inner wall of the sliding sleeve 15 can facilitate the sliding sleeve 15 to fall along the limiting post 14, preventing movement obstruction when the float block 16 falls.

[0040] Please see Figure 3 The water-holding cylinder 3 has multiple sets of drainage channels 21 on its outside. These multiple sets of drainage channels 21 can drain excess test water, allowing the test water to be accurately filled and preventing excessive test water from affecting the test accuracy.

[0041] In use, firstly, the water supply mechanism 1 is placed on the asphalt pavement to be tested. A sealing filler is placed between the water supply mechanism 1 and the ground, and the counterweight 2 ensures full contact between the water supply mechanism 1 and the sealing filler. Then, the water supply mechanism 1 is opened to supply water, allowing the air at the bottom of the mechanism to be released through the vent valve 6. After the water is released through the vent valve 6, it is sealed. Then, the water tank 3 is filled. As the water falls, the lifting mechanism 4 will also fall, allowing the user to observe the water level from the higher marker 5. This detection device makes it easier to detect water seepage and provides more accurate results. When it is necessary to lower the water tank 3, the vent valve is opened. Valve 10 allows the test water inside the water tank 3 to fall through the connecting pipe 11 and the through hole 9, enabling the test water to fall for testing. After the drain valve 10 is opened, the water inside the water tank 3 falls, and then the float block 16 and the sliding sleeve 15 fall along the limiting post 14. At this time, the falling float block 16 can drive the column 17 and the indicator rod 18 to fall. Then the indicator rod 18 can be aligned with the corresponding indicator plate 20. At this time, the operator can observe the falling speed of the test water inside the water tank 3 from a higher position, which is convenient for accurate calculation of the road surface seepage performance. The multiple sets of ball bearings 22 set on the inner wall of the sliding sleeve 15 can facilitate the sliding sleeve 15 to fall along the limiting post 14 and prevent the float block 16 from being obstructed when falling.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
