Detection method for anti-channeling performance of waterproof roll

Abstract

The invention relates to a detection method for the anti-channeling performance of a waterproof roll. The detection method comprises the following steps that 1, a through hole is preformed in the waterproof roll, a mortar block is poured into the waterproof roll to form a test piece, and the test piece is demolded and cured, wherein the to-be-detected area of the waterproof roll is larger than or equal to the area of the installing surface of an anti-seepage instrument test piece installing base, the waterproof roll and the installing base are arranged in a sealed mode, the anti-seepage capacity of the mortar block is higher than the stress borne by the mortar block, and the bottom area of the mortar block is smaller than the area of the installing surface of the anti-seepage instrument test piece installing base; 2, the cured test piece is put into an anti-seepage instrument, the waterproof roll surface faces water, whether water seeps out of the bonding edge of the waterproof roll and the mortar block or not is observed at any time under the specified time and pressure condition, and once the water seeps out, it can be determined that the anti-channeling performance of the waterproof roll is not qualified. According to the method, on the premise that it is guaranteed that the pressure difference is generated in the test process, the problems that sample preparation is tedious, the test piece is cumbersome, the repeatability is poor, and the success rate is low are solved.

Description

technical field [0001] The invention relates to a method for detecting the anti-channeling performance of a waterproof coiled material. Background technique [0002] As we all know, the leakage rate of buildings in our country remains high, and one of the problems is that there is a water channeling layer between the waterproof layer and the structural layer. Once a point of the waterproof membrane is damaged, water will leak to the base layer through the damaged point. If the waterproof membrane has good water resistance, it only needs to repair the damaged point to solve the leakage problem; and if If the waterproof membrane and the base layer are not well bonded, water will spread and penetrate between the membrane and the base layer through the damaged point, resulting in large-scale water seepage. At this time, the entire surface needs to be repaired or waterproofed again to solve the leakage. The reliability of the waterproofing system can only be improved by improvin...
