Description

Technical Field

[0001] The utility model relates to the technical field of water seepage detection, and more specifically to an indoor water seepage test structure for rutting parts. Background Art

[0002] The rutting specimen is suitable for making asphalt mixture specimens in the laboratory by the wheel rolling method. The specimen can be used for asphalt mixture mechanical property tests such as determining the high temperature rutting resistance of asphalt mixture and determining the high temperature stability of asphalt mixture ratio design.

[0003] The Chinese patent document with publication number CN101666727B in the prior art provides a ring-shaped pavement structure loading test device. It is aimed at the problems that the existing pavement acceleration loading equipment is large in size, has a long manufacturing and use cycle, is expensive, and is complicated to operate. The inner and outer sleeves are sheathed together, the annular bottom plate is arranged between the inner and outer sleeves, the annular bottom plate is fixedly connected to the bottom end surfaces of the inner and outer sleeves, and the area surrounded by the annular bottom plate and the inner and outer sleeves constitutes an annular groove. The motor is arranged in the inner cavity of the inner sleeve, and the output shaft of the motor is transmission-connected to the rotary joint. The guide groove of the rotary joint is equipped with a depth adjustment device rollingly connected thereto, and two test vehicles are arranged in the annular groove. One end of the connecting frame is fixedly connected to the test vehicle, and the other end is fixedly connected to the depth adjustment device. Two displacement meters are arranged in the annular groove. The present invention has the advantages of small size, simple structure, low cost and simple operation, and is suitable for loading tests on various asphalt concrete pavement structures.

[0004] Based on the above-mentioned comparative documents, water permeability is an important property of rutting parts, which will affect the quality of the road surface. This requires testing the water permeability of rutting parts. The existing rutting part water permeability test structure is not convenient for simultaneously testing and comparing rutting parts with multiple different proportions, and it is not convenient to clean the rutting parts after solidification. When cleaning, the staff needs to be close to the platform, and the waste generated by cleaning is easy to scatter on the platform, which will increase the cleaning pressure.

[0005] The existing rutting part water seepage test structure has the above problems. In view of this, we propose an indoor rutting part water seepage test structure. Utility Model Content

The bolts are connected between the outer wall of the water seepage detection barrel 21 and the fixing block 5 to fix the water seepage detection barrel 21 on the test platform 1 so that liquid will not enter between the two.

[0039] It is worth noting that an annular edge 61 is fixedly provided at the bottom of the outer wall of the water seepage detection barrel 21, and a plurality of through holes 62 are opened on the edge 61; by setting the edge 61, the edge 61 and the water seepage detection barrel 21 are integrally formed, and the through holes 62 are opened on the edge 61, which can facilitate the installation of bolts.

[0045] Working principle: first, add a certain amount of rutting piece material to be tested into the water seepage detection barrel 21, and after the rutting piece raw material inside the water seepage detection barrel 21 is solidified to form a material block, use glue to seal the inner wall of the water seepage detection barrel 21 and the solidified rutting piece material. After the glue between the two is solidified, use the hydraulic cylinder 28 to push the piston 26 downward. Since the water storage chamber 25 is connected to multiple water seepage detection barrels 21 by water pipes, the water in the water storage chamber 25 will be pressurized and transported to the middle and lower part of the water seepage detection barrel 21 through the water inlet hole 22, and then observe the test conditions on the upper surface of the solidified rutting piece material block, thereby realizing the test detection of the rutting piece material.
