Concrete is one of the most important civil engineering materials in contemporary times. It is made of cementitious materials, granular aggregates, water, and admixtures and additives added when necessary in a certain proportion, and is evenly mixed and compacted. It is widely used in road and bridge construction. In the early stage of construction, concrete testing equipment is needed to detect the water seepage of concrete to evaluate whether it meets the production quality requirements.

When the present invention is used, the slotting mechanism opens an annular sealing groove on the top of the concrete structure. After the sealing groove is opened, the opening of the lifting cover moves to the inside of the sealing groove, and water is injected into the inside of the lifting cover through the water inlet pipe.

[0016] The working principle and beneficial effects of the present invention are:

[0017] 1. By setting a positioning mechanism, a crescent pin matching the large spur gear is provided on the inner side of the first rectangular slide bar, so that the large spur gear can drive the first rectangular slide bar to move laterally due to rotation. When the first hydraulic cylinder and the output end of the guide tube are reset, the first drive motor is started, and the output end of the first drive motor drives the second bevel gear to rotate, thereby driving the first bevel gear to drive the rotating shaft to rotate in a circle. In this process, since the first small spur gear is fixed, the reciprocating screw rod is driven to drive the large spur gear to rotate, thereby driving the first rectangular slide bar to move laterally, so as to push the concrete slab to flip to the front groove and move it to the position directly above the clamping sleeve, so as to facilitate liquid penetration detection. By repeating the above operation, penetration detection can be performed on different positions of the four sides of the concrete slab, thereby improving the effect of concrete slab penetration detection;

[0018] 2. By arranging the cooperation of the suction pump and other parts, the bottom of the guide pipe is away from the bottom of the compression sleeve for a certain distance. When the penetration test is carried out in the groove of one place of the concrete slab, the suction pump is started, and the output end of the suction pump sucks the liquid retained in the compression sleeve into the collection bucket through the first hose and the guide pipe, so as to reduce the residual liquid in the groove and the compression sleeve, and avoid the excess liquid from flowing into other grooves during the turning process of the concrete slab, so as to avoid interference with the next detection, thereby improving the accuracy of the next detection;

[0019] 3. By arranging the cooperation of the L-shaped power rod and other parts, when the concrete slab is placed on the top of the two supports, the second drive motor can be started, and the output end of the second drive motor drives the one-way threaded screw to rotate, thereby driving the slider to drive the connecting rod to move downward, thereby driving the two L-shaped power rods to move downward, and when the inclined surface on the inner side of the L-shaped power rod contacts the spherical block, the spherical block is pushed to drive the second rectangular sliding rod to move toward the outer wall of the concrete slab, and the concrete slab can be pushed to the center position of the support through the two second pressure plates, so that the position of the concrete slab can be calibrated, and at the same time, the concrete slab can be supported during the circular flipping of the concrete slab, thereby improving the stability of the concrete slab during the flipping process;

[0020] 4. By setting the cooperation of the first pressure plate and other parts, a limiting slide groove matching the slider is opened on the inner side of the third fixed seat. When the slider moves downward, it drives the second small spur gear to move downward. Since the spur rack is fixed, the second small spur gear drives the first pressure plate to rotate toward the top of the concrete slab through the rotating shaft. When the slider moves to the specified position, the first pressure plate is pressed against the top of the concrete slab to press the concrete slab, thereby facilitating the concrete slab to be supported during the circular flipping process, thereby further improving the overall practicality of the device.
