Description

Technical Field

[0001] The present application relates to the technical field of road construction monitoring equipment, and in particular to a road surface water seepage meter and a detection method for road construction monitoring. Background Art

[0002] At present, in the process of road construction, the detection of road surface water seepage performance is a very important task, because it is related to the quality and safety of the road surface. The existing water seepage meter includes a measuring cylinder, an upper plate, a joint pipe, a base, a bracket, a weight block and an accessory marking ring. During the test, the test piece and the road surface to be tested placed on a solid plane are cleaned, the marking ring is placed, and the marks are drawn along the inner ring and the outer ring with chalk respectively. A thin layer of sealing material is applied between the inner and outer marking rings, and the water seepage meter is pressed hard on the sealing material so that the base of the water seepage meter and the sealing material ring match. Close the instrument valve and fill the water into the water seepage meter, fill it to the mark line position, and then quickly turn on the switch. When the water level drops by 100ml, start the ink to make the water turn light red. The stopwatch reads the water level scale on the measuring cylinder once every 60 seconds until the water level drops by 500ml. For the above-mentioned related technologies, leakage will occur between the base of the water seepage meter and the road surface during use, and there is a defect of low accuracy of the detection data.

[0003] The related technology discloses a water seepage meter, which melts paraffin into liquid through a heating tube and drips onto the ground through a ring plate. When the paraffin cools, the base is connected to the ground. At the same time, the liquid paraffin can easily flow into the closed gaps in the road surface, thereby reducing the possibility of detection water being lost along the road surface texture; increasing the possibility of detection water seeping into the ground along the open gaps; thereby improving the accuracy of the detection data.

[0004] The above-mentioned related technologies have the following defects: when connecting the base to the ground, it is first necessary to melt the paraffin, so that the melted paraffin flows into the closed gaps in the road surface, and then wait for the paraffin to completely solidify before a sealed connection between the base and the ground can be achieved. After the use of the infiltration meter, the paraffin on the infiltration meter and the road surface needs to be cleaned. The application process of the paraffin consumes a lot of time, which reduces the working efficiency of the infiltration meter. Summary of the invention

The overall technical solution realizes thorough cleaning and effective sealing before road water seepage detection, ensures accurate and reliable test results, and improves the detection efficiency.

[0055] The implementation principle of a road surface water seepage meter and detection method for road construction monitoring in the present application embodiment is as follows: Move the trolley 1 to the location on the road that needs to be inspected.

[0056] The detection mechanism 2 descends, so that the bristles of the annular brush 312 contact the road, and the annular sealing assembly 23 is still spaced apart from the road surface. First, the fan 35, the second valve 342, the third valve 343 and the fourth valve 343 are started to initially blow away the dust on the part to be detected. Then, the water pump 37, the water pump 37 and the fourth valve 344 are started, and the annular brush 312 rotates to brush the road, and at the same time, the trolley 1 is moved to brush the part to be detected on the road.
