Description

Technical Field

[0001] The utility model relates to the field of civil engineering, in particular to a soft soil foundation grouting reinforcement device. Background Art

[0002] Soft soil foundation refers to a foundation composed of silt, silty soil, backfill, miscellaneous fill or other highly compressible soil layers. This type of foundation is characterized by low strength, large and long-lasting deformation, high water content and poor permeability. These characteristics of soft soil foundations mean that directly constructing buildings on them may cause problems such as horizontal displacement and uneven settlement of the building, and may even cause cracks in the building, and in serious cases even collapse accidents.

[0003] The existing soft soil foundation reinforcement is achieved by inserting a grouting pipe into the ground, then connecting a grouting device to the grouting pipe, and starting the grouting device to allow the slurry to enter the grouting pipe and flow into the ground for reinforcement. During the grouting process, the grouting pipe is easily displaced under the action of the reaction force, resulting in insufficient grouting in some areas, which leads to poor stability in the use of the equipment.

[0004] Therefore, it is necessary to design a soft soil foundation grouting reinforcement device that can fix the grouting pipe to prevent the grouting pipe from shifting during the grouting process, resulting in inadequate grouting in some areas, and improve the stability of the device. Utility Model Content

[0005] In order to overcome the disadvantage that the grouting pipe is easily displaced under the action of reaction force during the grouting process, resulting in inadequate grouting in some areas, thereby causing poor stability in the use of the equipment, the utility model provides a soft soil foundation grouting reinforcement equipment that can fix the grouting pipe to prevent the grouting pipe from shifting during the grouting process, resulting in inadequate grouting in some areas, thereby improving the stability of the use of the device.

[0006] The technical implementation scheme of the utility model is: a soft soil foundation grouting reinforcement device, comprising a first sleeve, a drill bit and a grouting pipe, the lower side of the first sleeve is connected with the drill bit, and the inner side of the first sleeve is clamped with the grouting pipe.

[0007] As a further preferred solution, a plurality of grouting holes are opened on the first sleeve.

[0008] As a further preferred solution, a connector is also included, and the upper side of the grouting pipe is connected with the connector.

[0009] As a further preferred embodiment, it also includes a closing frame, a second sleeve and a first telescopic spring. The first sleeve is connected to multiple second sleeves, each of the second sleeves is slidably connected to the closing frame, and the first telescopic spring is connected between the closing frame and the adjacent second sleeves.

[0010] As a further preferred scheme, it also includes a fixed block, a guide rod, a clamping frame and a second telescopic spring. The upper part of the grouting pipe is connected to the fixed block, the left and right sides of the fixed block are connected to the guide rods, the guide rods are slidably connected to the clamping frame, and the second telescopic spring is connected between the clamping frame and the adjacent guide rods.

[0011] As a further preferred solution, the clamping frame is L-shaped.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model pulls the clamping frame by hand to move outward along the guide rod, the second telescopic spring is squeezed, and after the grouting pipe touches the bottom, the clamping frame is released, the second telescopic spring rebounds, and the clamping frame moves and resets to clamp the first sleeve, thereby fixing the grouting pipe, preventing the grouting pipe from shifting during the grouting process, resulting in inadequate grouting in some areas, and improving the stability of the device.

[0013] 2. The utility model enables the drill bit to contact the ground, so that the drill bit is inserted into the ground, thereby driving the first sleeve and the grouting pipe to move downward and insert into the ground. When the grouting pipe moves downward, the closing frame is in a closed state, thereby preventing soil from entering the grouting pipe and causing blockage, thereby ensuring the grouting effect and improving the grouting efficiency.

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0019] A soft soil foundation grouting reinforcement device, such as Figure 1-Figure 3As shown, it includes a first sleeve 1, a drill bit 2, a grouting pipe 3, a connector 4, a closing frame 5, a second sleeve 6, a first telescopic spring 7, a fixed block 8, a guide rod 9, a clamping frame 10 and a second telescopic spring 11. Twenty grouting holes are opened on the first sleeve 1 to facilitate the outflow of slurry. The drill bit 2 is connected to the lower side of the first sleeve 1. The grouting pipe 3 is clamped on the inner side of the first sleeve 1. The upper side of the grouting pipe 3 is connected to the connecting head 4 for external grouting equipment. Forty second sleeves 6 are connected to the first sleeve 1. The second sleeves 6 are all slidably connected with the closing frame 5. The first telescopic spring 7 is connected between the closing frame 5 and the adjacent second sleeves 6. The upper part of the grouting pipe 3 is connected with a fixed block 8. The left and right sides of the fixed block 8 are connected with guide rods 9. The guide rods 9 are all slidably connected with the clamping frame 10. The clamping frame 10 is L-shaped. The clamping frame 10 and the adjacent guide rods 9 are connected with second telescopic springs 11.

[0020] When it is necessary to reinforce the soft soil foundation by grouting, the device can be used. The device can be brought to the place where the soft soil foundation grouting reinforcement is required, and then the grouting pipe 3 is clamped with the first sleeve 1, and then the clamping frame 10 is pulled by hand to move outward along the guide rod 9, and the second telescopic spring 11 is squeezed. After the grouting pipe 3 touches the bottom, the clamping frame 10 is released, and the second telescopic spring 11 rebounds, and the clamping frame 10 moves and resets to clamp the first sleeve 1. The clamping frame 10 is L-shaped, so that the grouting pipe 3 can be fixed to prevent the grouting pipe 3 from shifting during the grouting process, resulting in inadequate grouting in some areas, thereby improving the stability of the device. After the installation is completed, the drill bit 2 is close to the ground When the grouting pipe 3 moves downward, the closing frame 5 is in a closed state, thereby preventing soil from entering the grouting pipe 3 and causing blockage, thereby ensuring the effect of grouting and improving the efficiency of grouting. Subsequently, the grouting equipment can be connected to the connector 4, so that the slurry enters the grouting pipe 3 from the connector 4. Under the pressure of the slurry, the closing frame 5 moves open along the second sleeve 6, and the second telescopic spring 11 is squeezed, so that the slurry flows out from the grouting hole on the first sleeve 1 to reinforce the soft soil foundation. After the grouting is completed, the second telescopic spring 11 rebounds, and the closing frame 5 moves to reset.
