Description

TECHNICAL FIELD

[0001] The application relates to the technical field of anti-permeation apparatuses, in particular to a full-automatic concrete anti-permeation apparatus. BACKGROUND

[0002] The concrete anti-permeation apparatus is a kind of instrument specially used for measuring the anti-permeation performance of concrete. It measures the change range of water in the concrete sample within a certain time through water pressure test on the concrete sample, that is, water is introduced into the concrete sample under a specified pressure, so as to evaluate the anti-permeation performance of the concrete sample and the change of the water content and the mass concentration of water molecules in the sample.

[0003] The existing patent (publication number: CN220603253U) discloses a concrete anti-permeation apparatus, which comprises an anti-permeation apparatus body and a plurality of core sample clamps. The top of the anti-permeation apparatus body is provided with a workbench. The core sample clamp comprises a bottom plate, an elastic sealing sleeve and a plurality of gland covers. The elastic sealing sleeve is placed on the surface of the bottom plate, and the plurality of gland covers are arranged around the elastic sealing sleeve. Limiting holes are arranged on the surface of the gland cover. The gland cover and the workbench are fixed together by using bolts, and the bolts pass through the limiting holes and the bottom plate from top to bottom in sequence. According to the technical scheme of the utility model, the gland cover and the workbench are fixed together by using bolts. By tightening the bolts, the gland cover generates extrusion force in the radial direction and the axial direction of the elastic sealing sleeve, and then the elastic sealing sleeve is deformed to tightly clamp and fix the test piece. The concrete anti-permeation apparatus and the core sample clamp can be suitable for test pieces with non-standard external dimensions, which avoids the waste of resources caused by the re-production of test pieces and improves the work efficiency.

[0004] When the above-mentioned device is disassembled after being installed, the test piece is clamped and fixed by the deformation of the elastic sealing sleeve, and the elastic sealing sleeve and the sample are in interference fit. When the elastic sealing sleeve and the sample are separated, the resistance is large, and it is not easy to separate. At the same time, by tightening the bolts, the gland cover generates extrusion force in the radial direction and the axial direction of the elastic sealing sleeve. When there are many samples to be measured, a plurality of bolts need to be installed, and the disassembly and installation are relatively cumbersome. When the fastening degree of individual bolts is not enough, the elastic sealing sleeve and the sample are not in close contact, which affects the test result. Utility model content
