AI Technical Summary

Technical Problem

The lack of existing technology for quantitative testing methods of the peel resistance of sprayed waterproofing materials under water pressure makes it difficult to promote and apply them in practical engineering.

Method used

A peel resistance testing device for sprayed membrane lining structures was designed. The peel resistance between the sprayed waterproof layer and the concrete layer was measured by combining an annular drainage structure and a water pressure gauge. The test was conducted using a step-by-step pressure method.

Benefits of technology

A method for evaluating the peel resistance of sprayed waterproofing materials under water pressure was provided, which identified the weak points in the waterproofing of composite structures and improved the application reliability and engineering accuracy of sprayed waterproofing materials.

Abstract

This invention discloses a peel resistance testing device and its manufacturing and testing methods for a sprayed membrane lining structure. The device includes a first concrete layer, a second concrete layer, a sprayed waterproof layer, a water inlet pipe, a first water outlet pipe, and a second water outlet pipe. A first drainage structure is provided between the sprayed waterproof layer and the first concrete layer, and a second drainage structure is provided between the sprayed waterproof layer and the second concrete layer. The water inlet pipe penetrates the first concrete layer and connects to the sprayed waterproof layer. The first water outlet pipe penetrates the first concrete layer and connects to one end of the first drainage structure. The second water outlet pipe penetrates the first concrete layer, the other end of the first drainage structure, and the sprayed waterproof layer, and connects to the second drainage structure. By employing the above technical solution, compared with existing technologies, this invention overcomes the deficiency of previous tests that only focused on the waterproof performance of the sprayed membrane itself while neglecting the water pressure peel resistance of the sprayed waterproof material, filling the gap in the testing of the water pressure peel resistance of double-sided bonded waterproof materials.
