Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, specifically to a waterproof membrane thickness measuring device. Background Technology

[0002] Waterproof membrane is a flexible building material that can be rolled up. It is widely used in road construction projects such as highways, tunnels, and railways. It can form a dense waterproof layer on the ground, effectively preventing the penetration of water, protecting the roadbed and road bridges from the erosion of water-based compounds, increasing the service life of road facilities such as highways and bridges, and improving the long-term stability and safety of road traffic. According to the different main components, it can be divided into three categories: asphalt waterproof membrane, polymer-modified asphalt waterproof membrane, and synthetic polymer waterproof membrane.

[0003] Testing the quality of waterproof membranes can effectively ensure that the waterproof membranes used in construction have qualified waterproof performance. During the construction process, waterproof membranes must not only withstand the tensile and compressive stresses during unrolling and laying, as well as the pressure from machinery, punctures, and trampling, but also the natural aging and loads during use. Therefore, relevant standards and specifications have put forward thickness requirements for different types of waterproof membranes.

[0004] Because the stress is not completely released when the waterproof membrane is rolled, unevenness may still occur on the surface or sidewalls after cutting. Measuring the thickness of the waterproof membrane requires taking multiple sample points at different locations for measurement. If a certain point is uneven, it will affect the stability of that point and cause errors in the measurement results. Therefore, it is necessary to develop a waterproof membrane thickness measuring device to solve this problem. Utility Model Content
