Anti-lateral seepage asphalt pavement water seepage device with constant-pressure variable head and method

Abstract

The invention discloses an anti-lateral seepage asphalt pavement water seepage device with a constant-pressure variable head and a method, and belongs to the technical field of pavement engineering detection. Specifically, a testing box bottom plate is arranged in a testing box body; a sealing top cover and a sealing ring are arranged at the top of the testing box body; a sealing layer made of a waterproof material is additionally mounted at the periphery of the testing box body; a testing part is arranged in the middle of the testing box body; a water tank is adopted to supply water to the whole device through a water tube; a water body pressurizing cylinder is used as a water body pressurizing device; a pressurizing rubber piston is pushed to move downwards by a pressurizing vertical rod through a pressurizing load to pressurize a water body; a pressurized water body is in contact with the testing part through a water discharge tube; a seepage water body flows into measuring glass from water seepage holes, a water collection tank and a water guide tube. By adopting the device and the method, influence of lateral seepage and the variable head to testing data can be effectively eliminated, the detection data stability can be greatly improved, the water seepage property of an asphalt pavement can be relatively and accurately judged, artificial errors made by different testing operators can be effectively reduced, the detection data can be relatively good in stability, and good economic benefits and wide application prospects can be achieved.

AI Technical Summary

Benefits of technology

This patented technology relates to an apparatus for detecting leaks or holes that occur during construction materials like concrete roadways (roads). It involves applying high pressure onto a liquid substance called water, causing tiny bubbles to form when they hit certain parts inside the material being tested. These small bubble sizes help identify any cracks formed due to these defects. By analyzing this testing data obtained from the sample, we aim to predict how well the new material will perform properly over time without experiencing damage. Additionally, there may exist other factors affecting leak resistance including temperature changes, moisten conditions, and vibrations generated within the vehicle's interior environment. Overall, our technical effect lies in improving the accuracy and reliability of determining whether a specific type of surface needs repair or replacement while ensuring safety standards compliance across various industries.

Problems solved by technology

This patents describes various technical problem addressed by these inventors relating to improving the effectiveness of detecting water leakages caused by rainwater entering through cracks formed at the edges of roads due to imperviousness of their construction material. Current methods involve testing only one aspect - either continuously or periodically, but they cannot accurately determine if there was any water leaks inside them. Additionally, current devices require frequent maintenance because they lose some of its properties overtime.
