Abstract

The invention discloses an artificial water body simulation test device for hydrophobic particles and a test method thereof, belongs to the technical field of anti-seepage breathable materials, and aims to solve the problems that no special equipment is provided for anti-seepage performance testing of the artificial water body anti-seepage structure, the anti-seepage performance of the artificialwater body anti-seepage structure needs to be evaluated according to seepage quantity after construction, results lag and construction cannot be accurately and reasonably guided. The artificial waterbody simulation test device comprises a sealing device, a water inlet, an exhaust valve and a water leakage opening. The water inlet and the exhaust valve penetrate through the top end of the sealingdevice, and the water leakage opening penetrates through the bottom end of the sealing device. The method comprises the steps of side wall sealing treatment, bottom anti-seepage structure laying, experimental device sealing, anti-seepage test and result judgment. By means of the simulation test device, whether the hydrophobic particles and the anti-seepage structure of the hydrophobic particles can meet the anti-seepage requirement of the artificial water body or not is tested before engineering construction of the artificial water body, the hydrophobic particles and the anti-seepage structureare adjusted in time in the design stage, and important engineering significance is achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-permeation gas materials, and in particular relates to an artificial water body simulation test device for hydrophobic particles and a test method thereof. Background technique [0002] Hydrophobic particles are a kind of anti-seepage material with air permeability, which is prepared from aggregate particles such as gold mine tailings, lead-zinc tailings, aeolian sand, and desert sand as the main raw materials. By laying hydrophobic particles instead of geotextiles at the bottom of the artificial water body, the problem of water impermeability and airtightness is solved. It can not only achieve a good anti-seepage effect, but also connect the water body to the earth, increase the dissolved oxygen in the water body, and keep the water quality fresh. [0003] At present, the anti-seepage performance test of waterproof materials uses a waterproof membrane impermeability tester. This equipment is only su...
