It is widely used in municipal engineering, tunnel engineering, roadbed and pavement engineering, slope engineering, structural engineering foundation treatment, geothermal engineering and other construction engineering fields. Grouting experimental research is one of the main ways to study grouting technology. Determining the optimal grouting parameters and revealing the grouting reinforcement mechanism based on the properties of the rock and soil body and engineering needs is one of the main research contents of grouting technology. After grouting in the rock and soil body is completed, the study of the physical and mechanical properties of the grouting reinforcement body of the rock and soil material is a key link in the optimization of grouting parameters and the study of the reinforcement mechanism.

[0003] In indoor grouting experiments, how to effectively and quickly obtain grouting solid samples is one of the difficulties that plagues grouting technology research. In the prior art, the penetration grouting device uses a cylinder and upper and lower covers connected by threads.

The upper and lower ends of the grouting container body 1 are respectively provided with an upper cover 2 and a lower cover 3. The upper cover 2 is provided with a grouting inlet, and the lower cover 3 is provided with a water outlet. The grouting pipe is arranged inside the grouting container body 1, and the two ends of the grouting pipe are respectively connected with the grouting inlet and the water outlet; the grouting container body 1 is composed of two semi-cylindrical pipe walls 11 with staggered seams spliced ​​in the longitudinal direction, the grouting container body 1 is a cavity columnar structure, and the pipe wall hoop 4 is arranged outside the grouting container body 1.

[0032] In the technical solution provided by the embodiment of the utility model, the upper end of the grouting pipe is connected to the slurry inlet of the upper cover 2. During grouting, after entering the grouting pipe through the slurry inlet, the cement slurry in the grouting pipe enters the cavity of the grouting container body 1 through the holes in the wall of the grouting pipe.

[0033] After the grouting is completed, the sampling time of disassembling the grouting device is determined according to the specific composition of the cement slurry actually grouting. When sampling, first remove the pipe wall hoop 4 constraining the grouting container body 1, separate the two longitudinally spliced ​​semi-cylindrical pipe walls 11, and then take the sample. The staggered splicing of the two semi-cylindrical pipe walls 11 can effectively reduce the gap between the two semi-cylindrical pipe walls 11, and prevent the grouting cement slurry from flowing out of the gap of the semi-cylindrical pipe walls 11.

[0034] The pipe wall hoop 4 can further play the role of constraining the semi-cylindrical pipe wall 11, so that the splicing shape of the grouting container body 1 remains stable.

[0036] At this time, the second circular plate extends into the interior of the grouting container body 1, which can achieve a good sealing effect. At the same time, the diameter of the first circular plate 21 is larger than the diameter of the grouting container body 1, which can facilitate the removal and installation of the entire upper cover 2.

[0037] Similarly, in order to facilitate the disassembly and assembly of the lower cover 3 and at the same time ensure a good sealing effect of the lower cover 3 on the grouting container body 1 to prevent the injected cement slurry from flowing out from the gap between the lower cover 3 and the grouting container body 1, in a grouting device provided by an embodiment of the utility model, the lower cover 3 includes: a third circular plate 31 and a fourth circular plate 32 are superimposed and composed, the third circular plate 31 and the fourth circular plate 32 are both provided with a water outlet, and the third circular plate 31 and the fourth circular plate 32 are a concentric circle structure; the diameter of the third circular plate 31 is larger than the diameter of the grouting container body 1, and the third circular plate 31 is arranged below the lower wall surface of the grouting container body 1; the diameter of the fourth circular plate 32 is smaller than the diameter of the grouting container body 1, and the fourth circular plate 32 extends into the interior of the grouting container body 1.

[0038] At this time, the fourth circular plate 32 extends into the interior of the grouting container body 1, which can achieve a good sealing effect. At the same time, the diameter of the third circular plate 31 is larger than the diameter of the grouting container body 1, which can facilitate the removal and installation of the entire lower cover 3.

[0039] To further optimize the technical solution, since the grouting device is composed of multiple parts, in order to better ensure the stability of the overall structure of the grouting device, the grouting process is usually pressurized to prevent the stability of the grouting structure from being affected by the large external pressure during the grouting process. The grouting device provided by the embodiment of the utility model also includes: a plurality of screw rods 5; the outer edges of the first circular plate 21 and the third circular plate 31 are respectively provided with mounting holes, and the two ends of the screw rod 5 pass through the mounting holes of the first circular plate 21 and the third circular plate 31 respectively, and are fixed to the first circular plate 21 and the third circular plate 31 respectively. In the process of actual application, the screw rod 5 is respectively connected and fixed to the first circular plate 21 and the third circular plate 31 by screws 91 and nuts 92. At this time, the screw rod 5 can play a role in further enhancing the structural stability of the grouting device. In the process of actual application, four parallel screw rods 5 can be arranged at equal intervals.
