Description

Technical Field

[0001] The utility model relates to an underwater concrete pouring and forming test device. Background Art

[0002] Underwater concrete is a kind of special concrete that can realize the land-based construction of underwater concrete. It has the characteristics of underwater non-separation, self-compactness and slow setting. In order to simulate on-site construction and test the fluidity, anti-dispersion and strength of the test block after forming of underwater concrete mixture, it is necessary to conduct concrete simulation pouring and forming test.

[0003] The existing test method is to place the standard concrete test mold in a container filled with water (the water level is not lower than the test mold height); invert the slump cone and place it on a 150mm×150mm steel plate. After filling, lift the slump cone and the steel plate at the same time and place them directly above the underwater forming mold. The lower opening needs to be observed by eye to align the test mold, and the steel plate just touches the water surface. Remove the steel plate and let the mixture slowly fall into the concrete forming mold for forming and curing. It is easy to leak and disperse during pouring, and the pouring is uneven, resulting in deviations in the test results; at the same time, the pouring volume cannot be controlled and quantified, and the water-land ratio and cement separation cannot be determined by the pouring volume and forming volume in the future; and the pouring requires two people to operate, which is difficult and labor-intensive. Utility Model Content

[0004] Purpose of the utility model: The purpose of the present invention is to provide an underwater concrete pouring and forming test device with a quantifiable pouring amount and without leakage and dispersion of the mixture during the pouring process.

[0005] Technical solution: The underwater concrete pouring and molding test device described in the utility model comprises a water tank and a mounting frame erected above the water tank; a pouring funnel is fixedly connected to the mounting frame, and scale lines for measuring the pouring amount are provided on the side walls of the pouring funnel, and the mounting frame comprises at least four support rods, which are retractable rods for adjusting the height of the mounting frame relative to the water tank; a laterally movable cover plate is provided at the bottom of the pouring funnel, and a positioning rod for positioning the pouring funnel and the standard test mold is also fixedly connected to the pouring funnel. Before pouring, the positioning rod is adjusted to fit the outer wall of the standard test mold.

[0006] Wherein, the perfusion funnel is a transparent perfusion funnel made of plastic.

[0007] Wherein, the perfusion funnel is fixed on the mounting frame through a connecting piece.

[0008] Wherein, the positioning rod is fixedly connected to the perfusion funnel through a mounting piece.
