Description

Technical Field

[0001] The invention belongs to the technical field of waterproof coiled material detection, and more specifically, particularly relates to a performance detection device for waterproof coiled material for construction. Background Art

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to resist the leakage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. Therefore, performance testing of waterproof membrane is a key step to ensure project quality and guarantee the use effect.

[0003] The water permeability of waterproof membrane is an important indicator to measure its waterproof performance. The lower the water permeability, the stronger the ability of waterproof membrane to prevent water penetration. High-quality waterproof membrane should have extremely low water permeability to ensure that buildings or other engineering structures can effectively prevent water intrusion when facing various water sources such as rainwater and groundwater, thereby protecting the internal structure from water damage, extending the service life of the building and ensuring its use function.

[0004] At present, the dynamic water pressure test method is generally used to test the water permeability of waterproof membranes. Through water pumps and other equipment, a certain dynamic water pressure is applied to the waterproof membrane to simulate the water pressure fluctuations that may occur in actual use, observe the performance of the membrane under dynamic water pressure, and evaluate its impermeable performance by comparing the performance changes of the membrane before and after the test. However, in the actual use of waterproof membranes, waterproof membranes may be subjected to various stresses, causing the base layer of the membrane to extend and deform. In existing tests, it is difficult to obtain the water permeability of the membrane after extension and deformation, resulting in the test results cannot fully reflect the water permeability of the membrane in actual use.
