Description
Technical Field
The utility model relates to a test equipment technical field especially relates to a facade waterproof layer slippage capability test device.
Background
After waterproof construction of the basement vertical wall is finished, backfill construction is carried out at a later stage, if quality control of the backfill construction is not in place, when the friction force generated by backfill settlement on the coiled material is greater than the shearing strength of the coiled material and the base layer, the coiled material is bound to slide, and waterproof quality accidents are caused.
In the current material specification, the anti-sliding performance of the material is generally roughly judged only by the bonding strength or the peeling strength of the material, and the two parameters cannot truly reflect the real anti-sliding performance of the basement vertical wall waterproof layer. The backfill soil can generate a vertical compressive stress and a downward tensile stress on the waterproof coiled material in the process of sedimentation. The force form is not completely consistent with the bonding strength and the peeling strength.
At present, a mode of hanging a heavy object below a coiled material is basically adopted in a simulation experiment, or a mode of directly measuring the shear strength of the coiled material is adopted, and the test method has the following defects: the backfill settling process has a compressive stress perpendicular to the surface of the coiled material, which cannot be restored. The method is actually equivalent to applying a tension value to the coiled material, namely a line stress, testing the maximum tension of the coiled material at the dry-laid section, and in the actual engineering process, when the backfill slides down, a surface stress between the coiled material and the wall body is a shearing force. The method can test the shearing performance of the material by the adhesive, and cannot test the shearing performance of the coiled material and the coating after compounding.
