Description

Technical Field

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

[0002] With the development of transportation, the drainage performance of the road surface has been increasingly valued, so higher requirements have been put forward for the test accuracy of the pavement water permeability meter. As the asphalt pavement structure is subjected to water erosion that is far more severe than the road surface, the water pressure generated by the water on the road surface under the tires of high-speed vehicles can directly penetrate the asphalt surface layer. In order to minimize the water damage to the pavement structure layer, this requires that the interlayer bonding material of the asphalt pavement is not only highly water-tight, but also has a certain ability to resist water damage. At present, in road construction, a pavement water permeability meter is usually used to measure the amount of water that penetrates into a certain area of ​​the pavement per unit time. This is used as the pavement water permeability coefficient to evaluate the pavement water permeability performance, thereby reflecting the gradation composition of the pavement asphalt mixture, etc. The water permeability has become an important indicator for evaluating pavement performance.

[0003] With the popularity of water seepage meters in the field of highway construction, the biggest problem faced by existing water seepage meters during measurement is that there is usually leakage between the road surface and the base of the water seepage meter, which leads to serious distortion of the actual measurement results, especially for roads with poor road flatness. In order to solve this problem, the existing technology usually optimizes in two aspects: first, the surface of the road to be tested is polished in advance for flatness; second, the amount of adhesive is increased so that the water seepage meter can better fit the ground to avoid leakage between the water seepage meter and the ground.

[0004] For example, Document 1: Publication No. CN116256299B discloses a pavement water seepage meter and detection method for road construction monitoring and Document 2: Publication No. CN114544464B discloses a pavement water seepage meter and detection method for road construction monitoring;

[0005] In the above-mentioned document 1, a heating tube is used to heat the paraffin in the groove, so that the paraffin melts into liquid and drips onto the ground through the ring plate. When the paraffin cools, the base is connected to the ground, and the liquid paraffin is easy to flow into the closed gaps in the road surface, thereby reducing the possibility of the detection water being lost along the road surface texture; the above-mentioned document 2 uses a detachable clamping connection between a clamping ring and the base to adaptively adjust the stress and extrusion state of the three-dimensional silicone gasket, thereby adjusting the sealing and pressure resistance of the three-dimensional silicone gasket to adapt to the detected road body with different roughness.

[0006] Compared with the structure disclosed in Document 2, Document 1 has a wider applicability, and because it adopts the paraffin sealing method, the paraffin sealing method is a method of using paraffin materials to seal the surface and edges of the test sample to reduce the seepage loss during the test and ensure the accuracy of the test results. The basic principle of this method is to utilize the low permeability and plasticity of paraffin, melt it and apply it on the surface of the sample to form a sealing layer to prevent water from penetrating. It can also achieve better sealing when dealing with roads with poor flatness. However, the paraffin in Document 1 has poor solidification strength. After the paraffin is solidified, the permeability meter will be dismantled, and the paraffin will be broken into many small particles, making it difficult to collect, and dust, impurities, etc. will also be wrapped in the paraffin solid. Based on this background, the present invention proposes a road surface permeability meter and detection method for highway construction monitoring. This road surface permeability meter has strong sealing performance and can achieve the advantages of pavement impurity purging and sealing material recycling and reuse. Summary of the invention

In particular, it has good recyclability, recoverability, reuseability and environmental friendliness. Thermoplastic resin has strong sealing properties after curing, and high strength and toughness). Thermoplastic resin can achieve relative sealing between the road surface and the instrument. In addition, thermoplastic resin is easy to recycle and can be lifted up using the pry teeth 14. When used again, it only needs to be cut into pieces with scissors.
