DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:
[0021] As Figure 1 , Figure 2As shown in the figure, the utility model provides a device for grouting and concreting the retaining wall of a pile hole, which includes a protective cylinder 101. A fixed cover 102 is lapped on the top of the protective cylinder 101. A concrete grouting chamber 103 is arranged on the inner wall of the protective cylinder 101. A grouting pipe 104 fixedly connected to the top of the concrete grouting chamber 103 and communicating with its interior penetrates through the top of the fixed cover 102 and is slidably connected to a circular groove hole opened on the top of the fixed cover 102. Two symmetrically arranged cylinders 105 are fixedly connected to the bottom of the fixed cover 102. The output end of the cylinder 105 is fixedly connected to a lifting plate 106. An inner retaining wall assembly 2 is arranged at the bottom of the lifting plate 106. Four outer retaining wall assemblies 3 are annularly and symmetrically arranged at the upper and lower ends of the outer wall of the protective cylinder 101.
[0022] When constructing the pile hole, place the protective cylinder 101 at the designated position of the pile hole, quickly pour high-quality concrete into the concrete grouting chamber 103 from the grouting pipe 104, and then the inner retaining wall assembly 2 and the outer retaining wall assembly 3 provided can effectively protect the device. After the concrete in the concrete grouting chamber 103 solidifies, the device can be removed, and then the drilled hole can be grouted to form a pile.
[0023] As Figure 3 、 Figure 4 shown in the figure, the inner retaining wall assembly 2 includes a motor 201. The bottom of the motor 201 is fixedly connected to the middle of the top end of the lifting plate 106. The output end of the motor 201 penetrates through the bottom wall of the lifting plate 106 and is fixedly connected to a screw rod 202. The bottom of the screw rod 202 is fixedly connected to a rotating rod 203. A threaded cap 204 is threadedly connected to the outer wall of the screw rod 202. The bottom of the threaded cap 204 is rotatably connected to a rotating ring 205 located on the outer surface of the screw rod 202. Four annularly and symmetrically arranged connecting rods one 206 are rotatably connected to the outer wall of the rotating ring 205.
[0024] As Figure 3 、 Figure 4 shown in the figure, convex strips 209 are rotatably connected to one ends of the four connecting rods one 206 far away from the rotating ring 205. Fixed sleeves 208 are rotatably connected to the outer walls of the upper and lower ends of the rotating rod 203. Four annularly and symmetrically arranged connecting rods two 207 are rotatably connected to the outer walls of the two fixed sleeves 208. One ends of the connecting rods two 207 far away from the fixed sleeves 208 are rotatably connected to the convex strips 209. Inner retaining walls 210 are fixedly connected to one sides of the four convex strips 209 far away from each other.
[0025] When it is necessary to protect the inside of the protective cylinder 101, the cylinder 105 is started. The cylinder 105 pushes the lifting plate 106 down to the position that needs to be reinforced. At this time, the motor 201 in the inner protective wall assembly 2 is started. The motor 201 drives the screw rod 202 to rotate. The threaded nut 204 moves on the screw rod 202. The movement of the threaded nut 204 drives the rotating ring 205 connected to it to move up and down, thereby driving the connecting rod one 206 connected to the rotating ring 205 to rotate. Then, through the cooperation of the fixed sleeve 208, the connecting rod two 207 and the convex strip 209, the four inner protective walls 210 extend towards the inner wall of the pile hole and are closely attached to the inner wall of the pile hole, playing a role in protecting the inner wall of the protective cylinder 101. While the device flexibly adjusts the support position inside the protective cylinder, it can also adapt to inner walls of different shapes and sizes, thereby improving the overall strength of the device.
[0026] As Figure 5 shown, the outer protective wall assembly 3 includes a fixing plate 301. The arc-shaped side wall of the fixing plate 301 is fixedly connected to the outer wall of the protective cylinder 101. Two telescopic rods 302 are fixedly connected to the side of the fixing plate 301 away from the protective cylinder 101. The output ends of the two telescopic rods 302 are fixedly connected to the outer protective wall 303. A fixing frame 304 fixedly connected to the fixing plate 301 is arranged between the two telescopic rods 302. The inside of the fixing frame 304 is hollow and an internal threaded nut 309 is rotatably connected to the side away from the fixing plate 301. The inner wall of the internal threaded nut 309 is threadedly connected to a lead screw 305.
[0027] As Figure 5 shown, one end of the lead screw 305 away from the fixing plate 301 is fixedly connected to the outer protective wall 303. A limiting block is fixedly connected to the end of the lead screw 305 close to the fixing plate 301. A bevel gear two 308 is fixedly connected to the side of the internal threaded nut 309 close to the fixing plate 301. A bevel gear one 307 is meshed and connected to the top of the bevel gear two 308. A motor two 306 is fixedly connected to the top of the fixing frame 304. The output end of the motor two 306 penetrates through the inner top wall of the fixing frame 304 and is fixedly connected to the bevel gear one 307.
[0028] When it is necessary to protect the outer wall of the protective cylinder 101, the motor two 306 is started. The motor two 306 drives the bevel gear one 307 to rotate, and then drives the internal threaded nut 309 to rotate through the bevel gear two 308, so that the lead screw 305 pushes the outer protective wall 303 to extend outwards and contact the outer wall of the pile hole, enabling the device to have a good double protection function inside and outside, improving the protection effect during actual use. At the same time, the opening degree of the outer protective wall 303 can be flexibly adjusted to enhance the wall protection effect.
[0029] Next, the working principle of the pile hole grouting concrete retaining wall device will be specifically described.
[0030] As Figures 1-5As shown in the figure, during use, first place the protective cylinder 101 at the designated position of the pile hole, and quickly pour high-quality concrete into the concrete grouting chamber 103 from the grouting pipe 104.
[0031] When it is necessary to protect the inside of the protective cylinder 101, start the cylinder 105. The cylinder 105 pushes the lifting plate 106 down to the position that needs to be reinforced. At this time, start the motor 201 in the inner retaining wall assembly 2. The motor 201 drives the screw 202 to rotate. The threaded nut 204 moves on the screw 202. The movement of the threaded nut 204 drives the rotating ring 205 connected to it to move up and down, thereby driving the connecting rod 206 connected to the rotating ring 205 to rotate. Then, through the cooperation of the fixed sleeve 208, the connecting rod 207 and the convex strip 209, the four inner retaining walls 210 extend towards the inner wall of the pile hole and fit tightly with the inner wall of the pile hole, playing a role in protecting the inner wall of the protective cylinder 101. This enables the device to flexibly adjust the support position inside the protective cylinder while also adapting to inner walls of different shapes and sizes, thereby improving the overall strength of the device.
[0032] When it is necessary to protect the outer wall of the protective cylinder 101, start the second motor 306. The second motor 306 drives the first bevel gear 307 to rotate, and then drives the internal threaded nut 309 to rotate through the second bevel gear 308, so that the lead screw 305 pushes the outer retaining wall 303 to extend outwards and contact the outer wall of the pile hole, enabling the device to have a good dual internal and external protection function, improving the protection effect during actual use. At the same time, the opening degree of the outer retaining wall 303 can be flexibly adjusted to enhance the retaining wall effect.
[0033] Finally, after the concrete in the concrete grouting chamber 103 solidifies, the device can be removed, and then the borehole can be grouted to form a pile.
[0034] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
