[0002] In mountainous areas, high fill foundations have insufficient bearing capacity, insufficient compaction, uneven settlement or large settlement. During construction, the foundation is mainly reinforced by compaction grouting. The compaction grouting process is to inject slurry into the soil under pressure through a grouting pipe, forming a slurry-saturated slurry-soil combination around the grouting pipe, and squeezing and compacting the soil, which has a comprehensive reinforcement effect on the foundation soil.

[0003] In the prior art, grouting holes are provided on the grouting pipe. After the mud is transported into the grouting pipe, it flows into the foundation through the grouting holes at the bottom thereof. However, since the number, distribution position and distribution height of the grouting holes on the grouting pipe are fixed, the height and range of the grouting are fixed, and the reinforcement depths required for foundations in different terrain conditions are different. The existing grouting pipe cannot adjust the grouting range of the grouting pipe and the grouting holes according to the actual construction conditions. Moreover, a guide rail needs to be provided at the bottom of the grouting machine, and it needs to move along the guide rail. However, the guide rail is large in size and is not convenient to carry and install. Utility Model Content

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] The utility model provides a foundation treatment grouting device, comprising a moving mechanism 1 and a grouting pipe 2, and also comprising a lifting mechanism 3 fixedly connected to one side of the moving mechanism 1, the lifting mechanism 3 comprising a liftable fixing frame 31, the grouting pipe 2 comprising a pouring pipe 21 and a grouting pipe 22, the lower part of the grouting pipe 22 is slidably connected to the pouring pipe 21, the upper part of the pouring pipe 21 is fixedly connected to the fixing frame 31, the lower part of the pouring pipe 21 is provided with a plurality of grouting holes 211, the lower end of the grouting pipe 22 is fixedly connected with a sealing ring 4, and the sealing ring 4 is located between the outer wall of the grouting pipe 22 and the inner wall of the pouring pipe 21.

[0020] The foundation treatment grouting device can be moved to the grouting construction point by the moving mechanism 1. According to the required grouting depth, the grouting pipe 21 and the grouting pipe 22 of the grouting pipe 2 are driven to move downward together by the liftable fixing frame 31 of the lifting mechanism 3, so that the lower tip of the grouting pipe 21 is inserted into the foundation and is located at the required grouting depth, and the grout is delivered into the grouting pipe 2 through the external grouting equipment; when the required grouting depth is less than the height of the grouting hole 211 at the bottom of the grouting pipe 21, it is necessary to push the grouting pipe 22 in the grouting pipe 21, and adjust the position of the sealing ring 4 at the lower end of the grouting pipe 22, such as Figure 2 As shown, only the grouting holes 211 below the sealing ring 4 will be grouted into the foundation, and the grouting height H.

[0021] A foundation treatment grouting device also includes a clamping mechanism 5, which includes a limiting rod 51, a clamping ring 52 and an abutment rod 53. The lower end of the limiting rod 51 is fixedly connected to the fixing frame 31, the clamping ring 52 is fixedly connected to the upper end of the limiting rod 51, and the abutment rod 53 is threadedly connected to the side wall of the clamping ring 52. The upper part of the slurry delivery pipe 22 passes through the center of the clamping ring 52, and the abutment rod 53 can be screwed inwardly into the clamping ring 52 and abut against the surface of the slurry delivery pipe 22.

[0022] During the grouting process, the grouting pipe 22 can be manually held to manually adjust and maintain the height of the sealing ring 4 at the lower end of the grouting pipe 22 in the grouting pipe 21; by providing a clamping mechanism 5, the height of the sealing ring 4 can be fixed and maintained, making construction more convenient.

[0023] A foundation treatment grouting device also includes a guide structure 6, which includes two positioning plugs 61. A guide rope 62 is connected between the positioning plugs 61. The guide rope 62 passes through the interior of the moving mechanism 1, and the moving mechanism 1 can slide along the guide rope 62.

[0024] The upper part of the positioning plug 61 is provided with an annular guide plate 63 which is sleeved on the positioning plug 61, and one side of the annular guide plate 63 is provided with a groove 631 which can accommodate the guide rope 62. The upper end of the positioning plug 61 is also fixedly connected with an eccentric positioning disk 64, and the side of the eccentric positioning disk 64 away from the groove 631 is fixedly connected with two positioning columns 641, the gap between the two positioning columns 641 is aligned with the groove 631, and the guide rope 62 can be clamped in the gap between the two positioning columns 641.

[0025] The lifting mechanism 3 also includes a support plate 32, a telescopic cylinder 33 and a telescopic rod 34. The support plate 32 is fixedly connected to the moving mechanism 1, the telescopic cylinder 33 is fixed on the upper side of the support plate 32, the lower part of the telescopic rod 34 is slidably connected inside the telescopic cylinder 33, and the fixed frame 31 is fixedly connected to the upper end of the telescopic rod 34.

If the grouting height H needs to be adjusted, the abutment rod 53 needs to be unscrewed so that the slurry delivery pipe 22 can move up and down in the clamping ring 52, so that the slurry delivery pipe 22 drives the sealing ring 4 at its lower end to rise and fall in the grouting pipe 21 by manual force. After determining the new grouting height H, the abutment rod 53 is tightened again so that the slurry delivery pipe 22 is fixed to the clamping mechanism 5 again, and the grouting height H at this time is stable and unchanged.

[0027] The moving mechanism 1 includes a main body 11 for fixing the lifting mechanism 3. A slider 12 is provided below the main body 11. The slider 12 is provided with a guide hole for the guide rope 62 to pass through. The moving mechanism 1 can slide along the guide rope 62 through the slider 12. A pulley 13 is fixedly connected to the bottom of the slider 12.

[0028] By setting up the guide structure 6, it is ensured that the moving mechanism 1 can move in a straight line, and the position deviation of the slurry delivery pipe 2 during the grouting process is avoided; when in use, first fix the positions of the two positioning plugs 61, then pass the guide rope 62 through the guide hole in the slider 12, and then fix the two ends of the guide rope 62 to the two positioning plugs 61 respectively, pass the guide rope 62 through and clamp it in the gap between the two positioning columns 641, and then clamp the guide rope 62 into the groove 631 on the annular guide plate 63, and finally wrap the excess length of the guide rope 62 around the positioning plug 61.
