Abstract

The invention discloses a test device for simulating collision friction between a water stop material and ice and a test method thereof, and relates to a test device and a test method thereof. The problem that an existing test device cannot simulate rubber and ice collision friction and contact friction tests in an outdoor complex climatic environment is solved. A top plate and a bottom plate areinstalled at the two ends of an organic glass cylinder in a sealed mode, a sample rotating shaft is installed in the organic glass cylinder, one end of the sample rotating shaft is connected with an output shaft of a stepping motor, the other end of the sample rotating shaft is installed on the bottom plate in a rotating mode, and a tested water stop material is installed on the sample rotating shaft through a bolt. The method comprises the steps of installing a water stop material; injecting an anti-freezing solution and ice cubes into the organic glass cylinder; simulating the process of collision and friction between the water stop material and ice; ensuring that the test state is the same as the initial state; and after the test is finished, taking out the sample, carrying out tensilestrength and elongation at break test, and calculating the tensile strength and elongation at break. The device is used for simulating the collision friction between the water stop material and ice.

Description

technical field [0001] The invention relates to a test device and a test method thereof, in particular to a test device and a test method for simulating the impact and friction of water-stop materials and ice. Background technique [0002] In cold regions, as the ambient temperature rises and falls, the ice sheet bonded to the water-stop structure (rubber cover) will also rise and fall with the water level of the reservoir. It will collide and rub against the rubber cover, resulting in damage and failure of the water-stop structure. Ice friction damage of water-stop structures is an important indicator that restricts the safety of engineering structures in winter. How to correctly simulate the ice friction test under service conditions in cold regions is a difficult problem to be solved. [0003] The current test method mainly uses the method of repeatedly pushing and rubbing ice cubes on the water-stop structure, which cannot realize rapid testing, effectively change the f...
