Abstract

The invention discloses a device and a method for testing anti-seepage performance and air permeability, belongs to the field of detection equipment, and solves the problem that no special equipment and method exist in the anti-seepage and air permeability testing of anti-seepage and air-permeable particles. The device for testing anti-seepage performance and air permeability comprises a pressureregulating device and a plurality of groups of sealing testers. The method for testing anti-seepage performance comprises the following steps of: injecting water into the device and exhausting main pipes; carrying out blank pressurization testing; carrying out sample pressurization testing; recording tests; and expressing results. The method for testing air permeability comprises: blank pressurization measurement and result record; sample pressurization measurement; test recording; formula derivation; and result representation. The device provided by the invention tests the anti-seepage performance and air permeability of a granular sample through the change of the pressure and the difference of the change time of the pressure; and the method provided by the invention provides a technicalsupport for practical application of anti-seepage and air-permeable particles with different thickness in engineering and determines the optimal laying thickness.

Description

technical field [0001] The invention belongs to the field of detection equipment, and in particular relates to a test device for anti-seepage performance and air permeability performance and a test method thereof. Background technique [0002] The anti-permeation gas particle is 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. It has broad application prospects in the fields of construction, transportation, ecological protection and environmental governance, and can effectively solve the problems faced by human beings such as water shortage, soil environment deterioration, engineering leakage and ground subsidence. [0003] At present, the anti-seepage performance test of waterproof materials uses a waterproof membrane impermeability tester. This equipment is only suitable for the impermeability detection of asphalt and polymer membrane waterproof m...
