DETAILED DESCRIPTION

[0021] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0023] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0024] like Figures 1 to 4The main structure of the device shown is a mounting plate 1, the lower end of the mounting plate 1 is fixedly connected to a walking wheel 2, the top surface of the mounting plate 1 is fixedly connected to a U-shaped frame 3, the top surface of the U-shaped frame 3 is fixedly connected to a hydraulic cylinder 5, the telescopic end of the hydraulic cylinder 5 is transversely fixedly installed with a plurality of drilling devices 7, a grouting tube 8 is fixedly installed on the top surface of the mounting plate 1, the lower end of the grouting tube 8 is fixedly connected to a grouting pipe 10, a grouting pump 11 is fixedly sleeved on the pipe wall of the grouting pipe 10, and a telescopic hose 12 is fixedly connected to the end of the grouting pipe 10, a vertical plate 13 is fixedly connected to one side of the lower end of the mounting plate 1, and a slide groove 14 is longitudinally symmetrically provided on the side wall of the vertical plate 13, and sliders 17 are slidably connected to the inside of the two slide grooves 14, a horizontal plate 15 is fixedly connected between the two sliders 17, and a fixed block 16 is symmetrically fixedly connected to the side of the horizontal plate 15 away from the slider 17, a horizontal pipe 4 is rotatably connected between the two fixed blocks 16, and a plurality of grouting pipes are fixedly connected to the side wall of the horizontal pipe 4 9, and the number of drill bits in the drilling device 7 is arranged relative to the number and diameter of the grouting pipes 9. The inner top surfaces of the two fixed blocks 16 are provided with mounting grooves 19, and the top surfaces of the mounting grooves 19 are fixedly connected with springs 20, and the lower ends of the springs 20 are fixedly connected with clamping blocks 21. The side walls of the grouting pipes 9 are symmetrically provided with clamping grooves, and the clamping blocks 21 are clamped into the inside of the clamping grooves. When the grouting pipes 9 are moved out of the drilled holes, the grouting pipes 9 are rotated to drive the cross pipes 4 to rotate. When the clamping grooves opened on the side walls of the cross pipes 4 are aligned with the clamping blocks 21, the springs 20 will push the clamping blocks 21 to be clamped into the inside of the clamping grooves. At this time, because the clamping blocks 21 and the clamping grooves are both arc-shaped, when the cross pipes 4 rotate, the clamping blocks 21 will be moved out of the inside of the clamping grooves under the push of external force, thereby compressing the springs 20, and when the clamping blocks 21 are clamped into the inside of the clamping grooves without applying external force to them, the positions of the grouting pipes 9 and the cross pipes 4 can be limited, and the end of the telescopic hose 12 is fixedly connected to the side walls of the cross pipes 4.

[0026] The inner wall of the installation groove 19 is symmetrically provided with strip grooves, and the side wall of the clamping block 21 is symmetrically fixedly connected with rectangular blocks 6. The two rectangular blocks 6 symmetrically fixedly connected on the side wall of the clamping block 21 are respectively slidably connected to the inside of the two strip grooves symmetrically provided on the inner wall of the installation groove 19.

[0027] How it works

[0028] When the grouting reinforcement device for the bridge pile foundation is used, the device is first pushed to the position where the drilling and grouting reinforcement is required, and then the multiple drilling devices 7 and the hydraulic cylinder 5 are started. The drilling devices 7 and the drill bit are pushed downward by the hydraulic cylinder 5 until they pass through the mounting plate 1 and drill holes in the surrounding rock. After the drilling is completed, the hydraulic cylinder 5 is started in reverse to pull out the drill bit in the drilling device 7, and then the mounting plate 1 is pushed to drive the multiple grouting pipes 9 to align with the drilled surrounding rock holes, and then the cross plate 15 and the cross tube 4 fixedly connected to the side wall of the cross plate 15 and the multiple grouting pipes 9 fixedly connected to the side wall of the cross tube 4 are pressed down and inserted into the interior of the surrounding rock hole, and then the grouting pump 11 is started to pump the cement slurry in the grouting barrel 8 into the grouting pipe 10, and then the cement slurry is passed into the interior of the telescopic hose 12 through the grouting pipe 10, and finally the cement pump is passed into the interior of the grouting pipe 9 through the telescopic hose 12. Finally, cement slurry will be injected into the surrounding rock hole through the grouting pipe 9 to reinforce the bridge pile foundation by grouting. The number of drill bits in the drilling device 7 is relatively set to the number and diameter of the grouting pipe 9. When the filling is completed, the cross plate 15 is pulled upward, so that the cross pipe 4 and the grouting pipe 9 are pulled upward and moved out of the borehole through the cross plate 15. After the grouting pipe 9 is moved out of the borehole, the grouting pipe 9 is rotated to drive the cross pipe 4 to rotate. When the slot opened on the side wall of the cross pipe 4 is aligned with the block 21, the spring 20 will push the block 21 to be connected to the inside of the slot. At this time, because the block 21 and the slot are both arc-shaped, when the cross pipe 4 rotates, the block 21 will be moved out of the inside of the slot under the push of external force, thereby compressing the spring 20, and when the block 21 is connected to the inside of the slot without applying external force to it, the position of the grouting pipe 9 and the cross pipe 4 can be limited.
