[0028] As a further implementation of this solution, one side of the first metal cover 1 is fitted with the right side of the rubber strip 6, the size of the first metal cover 1 is the same as the size of the second metal cover 5, the front and rear ends of the second metal cover 5 are fixed with the side plates 3, and the lower ends of the second metal cover 5 and the first metal cover 1 are both through structures, which play a role in sealing between the first metal cover 1 and the second metal cover 5 to prevent concrete from overflowing;
[0029] As a further implementation of this solution, the number of square grooves 2 corresponds to the number of plugging grooves 7, the opening shape of the square grooves 2 is a rectangular body, and the opening shape of the plugging grooves 7 is a triangular body.

[0032] Working process: when sampling the concrete block sample, hold the grip shell 82 with one hand and the turning handle 85 with the other hand, and insert the whole device into the concrete pile. Before the insertion, the left side of the sealing plate 96 is flush with the left side of the square groove 2. At this time, the concrete enters the second metal cover 5 and the first metal cover 1. When the first metal cover 1 and the second metal cover 5 are completely filled with concrete, turn the turning handle 85. A rotating connecting ring is arranged on the outside of the turning handle 85 for easy operation. The turning handle 85 drives the threaded turning rod 84 to rotate. The threaded turning rod 84 passes through the turning handle 85. The bearing is rotatably connected to the inner side of the grip shell 82, which plays a role in limiting the threaded rotating rod 84.

At the same time, a rubber ring is installed on the outer side of the sealing plate 96. When the sealing plate 96 moves, it fits with the inner sides of the first metal cover 1 and the second metal cover 5 through the rubber ring. When the rubber triangle at the left end of the sealing plate 96 slides into the sealing groove 7, the concrete sample is between the first metal cover 1, the second metal cover 5 and the multiple sealing plates 96. At this time, the sampling of the concrete is completed, and the sampling of concrete at different depths is realized. The sampling effect and the singleness during concrete testing are achieved by pulling the handle 82, which drives the first connecting rod 81 and the second metal cover 5 to move out of the concrete pile. When the concrete inside the first metal cover 1 and the second metal cover 5 is dry and coagulated, the handle 85 is turned. The sealing plate 96 is moved out of the square groove 2 according to the above principle. The bolts 4 are disassembled to separate the first metal cover 1 and the second metal cover 5. The rubber strip 6 seals the first metal cover 1 and the second metal cover 5. At this time, the block of concrete can be taken out.
