Embodiment Construction

[0020] Such as Figure 1-Figure 8 , tire-sealed concrete impermeability test device, including a mold cover 1 and a bottom plate 9. The die set 1 is a hollow frustum metal cylinder with the same taper as the test piece 5 . The inner diameter of any section of the mold case 1 is slightly larger than the outer diameter of the corresponding section of the test piece 5 . Place the mold case 1 and the test piece 5 concentrically and align the bottom surfaces, and there is a uniform unilateral gap between the mold case 1 and the test piece 5. The inner wall of the mold cover 1 is provided with two undercutting grooves, and the sealing tire 2 is filled in the undercutting grooves. A flange is arranged on the outer edge of the large end of the mold sleeve 1, and several bolt grooves are evenly distributed in the circumferential direction of the flange. The inner end of the bolt groove is a semi-cylindrical surface, which opens outwards on the outside of the flange, and the bolt can...

Abstract

The invention relates to an anti-permeability test device for tire sealing concrete, and belongs to the technical field of building material detection. According to the technical scheme, the device comprises a die sleeve and a base plate. The die sleeve is a hollow truncated-cone-shaped metal cylinder, and the internal conical surface of the die sleeve is provided with two undercutting grooves. Each undercutting groove is internally provided with a seal tire. A flange is hinged to the large end of the die sleeve, and the periphery of the base plate is provided with a bolt groove. The base plate is installed on a test table top. During a test, a test piece is put on the base plate at first and sleeved with the die sleeve, then the die sleeve and the test piece are fixed through T-shaped bolts, and the combining surface of the die sleeve and the base plate is sealed by sealing rings. The seal tires are filled with pressure mediums and expand, side gaps of the test piece and the die sleeve are sealed, and a sealing pressure water cavity is formed in the bottom of the test piece. By adopting the test device, the hollow seal tires are good in flexibility, and the sealing effect can be ensured. When the seal tires are decompressed, tire bodies retract into the undercutting grooves under the function of support rings, almost no wear occurs, the operation is convenient and simple, andno pollution is caused. The test piece and the die sleeve can be separately conveyed, the die sleeve and the base plate are fixed through the T-shaped bolts, and the time and labor are saved during operation.

Description

technical field [0001] The invention relates to an anti-seepage experiment of concrete in construction engineering, and belongs to the technical field of detection of building materials. Background technique [0002] At present, most of the specimens used in concrete impermeability tests are prefabricated solid circular platforms with a small diameter of 175mm, a large diameter of 185mm, and a height of 150mm. Before the test, heat and soften the sealing packing such as the mixture of paraffin wax and rosin or the mixture of butter and talcum powder, and apply it evenly on the side of the circular frustum test piece, and then press the test piece into the mold sleeve with a press. After drying and curing, the test piece together with the mold cover is moved onto the test bench and fixed with screws. In order to ensure a reliable seal between the mold sleeve and the test bench, each mold sleeve must use 6 connecting screws, and there are 6 mold sleeves on each bench, and the...
