A highway pavement seepage detection device

Abstract

This utility model discloses a road surface seepage detection device, including a base plate. Three support rods are detachably mounted on the top of the base plate. A top plate is movably mounted on the top of each support rod. A positioning block is fixedly mounted at the center of the top of the top plate. A measuring barrel is movably mounted on the outer surface of the positioning block. A fixing plate is fixedly mounted on the bottom of the measuring barrel. Three clamping rods are fixedly mounted on the outer surface of the fixing plate. The top plate clamps the inner side of the clamping rods. The advantage of this utility model is that, through the cooperation of the clamping rods and the counterweight, the measuring barrel can be mounted on the surface of the positioning block during use. The clamping rods then clamp the top plate, and the elasticity of the compression spring pushes the counterweight out, locking it at the bottom of the top plate, thus fixing the measuring barrel. This prevents the measuring barrel from shaking on the top plate surface when vehicles are driving on the road, which could lead to water leakage inside the measuring barrel.

Description

Technical Field

[0001] This utility model relates to highway seepage detection, and in particular to a highway pavement seepage detection device. Background Technology

[0002] The pavement permeability coefficient is a key technical indicator for evaluating the drainage performance of asphalt pavements and asphalt mixtures. The magnitude of the pavement permeability coefficient directly affects the traffic safety of asphalt pavements in rainy weather. It is generally measured using a pavement permeability meter (also known as a pavement permeability coefficient measuring instrument). The pavement permeability coefficient is typically expressed as the volume of water that seeps into the pavement per unit time, and its unit is usually mL / min.

[0003] A pavement permeability meter is an instrument used to determine the permeability of asphalt pavement mixtures. It is primarily used to evaluate the permeability of road surfaces, assisting road construction and maintenance departments in conducting on-site measurements and experimental research. The pavement permeability meter consists of a base, a thick cylinder, and a thin tube, and is typically made of plexiglass for easy portability and operation.

[0004] However, in the existing technology, since vehicles usually drive on the road surface during testing, the measuring bucket is prone to shaking on the surface of the road permeability meter, which can lead to water leakage. In addition, there is a gap between the bottom of the road permeability meter and the road surface, which can easily cause water leakage and affect the test results. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a road surface water seepage detection device. Since vehicles usually drive on the road surface being tested, the measuring bucket is prone to shaking on the surface of the road surface water seepage meter, which can lead to water leakage. In addition, there is a gap between the bottom of the road surface water seepage meter and the road surface, which can easily cause water leakage and affect the test results.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A road surface seepage detection device includes a base plate, three support rods detachably mounted on the top of the base plate, a top plate movably mounted on the top of each support rod, a positioning block fixedly mounted at the center of the top of the top plate, a measuring barrel movably mounted on the outer surface of the positioning block, a fixing plate fixedly mounted on the bottom of the measuring barrel, three clamping rods fixedly mounted on the outer surface of the fixing plate, the top plate clamping the inner side of the clamping rods, and an airbag provided on the outer side of the bottom end of the base plate.

[0008] Preferably, a fixed platform is fixedly installed at the top of the base plate and the bottom of the top plate, and a pressure relief valve is detachably installed between the two fixed platforms. The outer surface of the pressure relief valve is provided with a valve handle.

[0009] Preferably, a water outlet is provided at the center of the bottom surface of the base plate, an air extraction port is provided on one side of the bottom surface of the base plate, and an air pump is provided at the top of the base plate near the air extraction port. The air extraction port is connected to the input end of the air pump, and a connecting pipe is movably installed at the output end of the air pump. The connecting pipe is connected to the inside of the airbag.

[0010] Preferably, two counterweights are movably mounted on the top surface of the base plate, and each counterweight has a snap-fit ​​groove on its surface, into which the support rod is movably snapped.

[0011] Preferably, the surface of each clamping rod is provided with a spring groove, and a limit block is slidably installed inside each spring groove. The top surface of the limit block is in contact with the bottom surface of the top plate, and a compression spring is movably installed between the limit block and the inside of the spring groove.

[0012] Preferably, one end of the compression spring is connected to the limiting block, and the other end of the compression spring is connected to the inner wall of the spring groove.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. By using the clamping rod and the counterweight, the metering barrel can be installed on the surface of the positioning block when the device is in use. At this time, the clamping rod will clamp the top plate and push the counterweight out through the elasticity of the compression spring, thus fixing the metering barrel and preventing the metering barrel from shaking on the surface of the top plate when vehicles are driving on the road, which could cause water leakage inside the metering barrel.

[0015] 2. By using the connecting pipe and the air bladder together, when the device is in use, air can be drawn from the inside of the air extraction port into the connecting pipe through the air pump. The extracted air is then filled into the air bladder, causing it to inflate. The air is continuously drawn in until the air bladder fills the gap between the bottom of the base plate and the ground. Once no more air enters the bottom of the base plate, the gap between the base plate and the ground can be sealed by the air bladder to prevent leakage of the detection water.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 As shown, a road surface seepage detection device includes a base plate 1. Three support rods 2 are detachably installed on the top of the base plate 1. A top plate 3 is movably installed on the top of each support rod 2. A positioning block 9 is fixedly installed at the center of the top of the top of the top plate 3. A measuring barrel 4 is movably installed on the outer surface of the positioning block 9. A fixing plate 5 is fixedly installed at the bottom of the measuring barrel 4. Three clamping rods 6 are fixedly installed on the outer surface of the fixing plate 5. The top plate 3 is clamped on the inner side of the clamping rods 6. An airbag 13 is provided on the outer side of the bottom end of the base plate 1.

[0023] A fixed platform 10 is fixedly installed at the top of the base plate 1 and the bottom of the top plate 3. A pressure relief valve 11 is detachably installed between the two fixed platforms 10. A valve handle 12 is provided on the outer surface of the pressure relief valve 11.

[0024] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, a water outlet 15 is provided at the center of the bottom surface of the base plate 1, an air extraction port 16 is provided on one side of the bottom surface of the base plate 1, and an air pump is provided at the top of the base plate 1 near the air extraction port 16. The air extraction port 16 is connected to the input end of the air pump, and a connecting pipe 14 is movably installed at the output end of the air pump. The connecting pipe 14 is connected to the inside of the airbag 13.

[0025] Two counterweights 7 are movably installed on the top surface of the base plate 1. Each counterweight 7 has a snap-fit ​​groove 8 on its surface, and the support rods 2 are movably snapped into the snap-fit ​​groove 8.

[0026] In this embodiment, through the cooperation of the connecting pipe 14 and the airbag 13, when the device is in use, air can first be drawn from the inside of the air extraction port 16 into the connecting pipe 14 by the air pump, so that the extracted air is filled into the inside of the airbag 13, thereby inflating the airbag 13, and continuing to draw air until the airbag 13 fills the gap between the bottom end of the base plate 1 and the ground. After no more air enters the bottom end of the base plate 1, the gap between the base plate 1 and the ground can be sealed by the airbag 13 to prevent the detection water from leaking out.

[0027] As a preferred technical solution in this embodiment, such as Figure 4 As shown, the surface of the clamping rod 6 is provided with spring grooves 18, and the inside of the spring grooves 18 is slidably installed with limit blocks 17. The top surface of the limit block 17 is in contact with the bottom surface of the top plate 3, and a compression spring 19 is movably installed between the limit block 17 and the inside of the spring grooves 18.

[0028] One end of the compression spring 19 is connected to the limiting block 17, and the other end of the compression spring 19 is connected to the inner wall of the spring groove 18.

[0029] In this embodiment, the clamping rod 6 and the counterweight 7 work together to allow the metering barrel 4 to be installed on the surface of the positioning block 9 when the device is in use. At this time, the clamping rod 6 will clamp the top plate 3 and push the counterweight 7 out through the elasticity of the compression spring 19, thereby fixing the metering barrel 4 and preventing the metering barrel 4 from shaking on the surface of the top plate 3 when vehicles are driving on the road, which could cause water leakage inside the metering barrel 4.

[0030] Working principle: When the measuring barrel 4 is installed on the surface of the positioning block 9, the clamping rod 6 will clamp the top plate 3 and push the counterweight block 7 out through the elasticity of the compression spring 19, thus fixing the measuring barrel 4. This prevents the measuring barrel 4 from shaking on the surface of the top plate 3 when vehicles are driving on the road, which could cause water leakage inside the measuring barrel 4.

[0031] In use, air can be drawn from the inside of the air extraction port 16 into the connecting pipe 14 using an air pump, so that the extracted air is filled into the airbag 13, thereby inflating the airbag 13. Continue to draw air until the airbag 13 fills the gap between the bottom of the base plate 1 and the ground. After no more air enters the bottom of the base plate 1, the gap between the base plate 1 and the ground can be sealed by the airbag 13 to prevent the detection water from leaking out.

[0032] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
