Waterproofing membrane bonding strength sampling device for hydraulic engineering

Abstract

The utility model discloses a kind of water conservancy waterproofing membrane bonding strength sampling device, belong to waterproofing membrane detection technical field, its technical scheme main points include pedestal, the top of the pedestal is provided with sampling frame, the inside of the sampling frame is provided with sampling assembly, the inside of the sampling assembly is provided with dust suction assembly, the sampling assembly includes annular gear ring rotationally connected in the inside of sampling frame, can solve the existing water conservancy waterproofing membrane bonding strength sampling device usually rely on hand to cut waterproofing membrane and sample, to be easily damaged waterproofing membrane and original bonding interface of base layer due to improper operation, leading to sampling test piece integrity deficiency, affect the accuracy of subsequent bonding strength detection result, and in sampling cutting process, it is easy to cause chippings to embed the bonding interface of roll material and base layer or interfere subsequent cutting operation, affect sampling precision and the reliability of detection result problem.
