[0025] Specific examples are given below.
[0026] See also Figures 1 to 5 As shown, a foundation pit interlocking pile foundation maintenance structure described in an embodiment of the utility model comprises a support seat 1; a steel plate 12 is hinged on the top of the support seat 1; a vertical plate 13 is fixedly connected to the top of the support seat 1; a motor 14 is fixedly connected to the middle of the vertical plate 13; a screw 15 is fixedly connected to the output end of the motor 14; a slide plate 16 is threadedly connected to the middle of the screw 15; a first connecting rod 17 is hinged to the middle of the slide plate 16; the first connecting rod 17 and the steel plate 12 are both in a hinged relationship; when working, the staff moves the device to the edge of the foundation pit and starts the device, which will start the motor 14 and rotate the screw 15 after the device is started. When the screw 15 rotates, the slide plate 16 will move along the screw 15 due to the threaded connection. When the slide plate 16 moves, it will move with the first connecting rod 17 and change the angle of the first connecting rod 17. When the first connecting rod 17 moves, it will exert pressure on the steel plate 12 and change the angle of the steel plate 12. Under the pressure of the first connecting rod 17, the steel plate 12 will approach the slope of the foundation pit until it contacts the edge of the foundation pit. When the steel plate 12 contacts the slope of the foundation pit, it will squeeze the soil layer inside the foundation pit to support the foundation pit; when the motor 14 rotates, it will move the screw 15 and make the first connecting rod 17 move with the steel plate 12 toward the slope of the foundation pit, so that the device can support slopes with different slopes, improve the stability of the soil inside the foundation pit during the construction of the bite pile foundation, and enhance the flexibility and adaptability of the device to the support and reinforcement of foundation pits with different slopes.
[0027] See also Figures 1 to 3As shown, the middle part of the slide plate 16 is hinged with the second connecting rod 2; the end of the second connecting rod 2 is hinged with a slider 22; the slider 22 and the vertical plate 13 are slidably connected; the middle part of the vertical plate 13 is rotatably connected with a rotating wheel 23; a plurality of springs 26 are fixedly connected to the bottom of the support seat 1; a pressure plate 25 is fixedly connected to the bottom of the spring 26; a steel wire rope 24 is fixedly connected to the top of the pressure plate 25; the steel wire rope 24 and the slide block 22 are both fixedly connected; the steel wire rope 24 and the rotating wheel 23 are in contact; when the slide plate 16 moves, it will also move with the second connecting rod 2, and when the second connecting rod 2 moves, the angle will change and exert a pulling force on the slider 22, so that the slider 22 will move along When the vertical plate 13 slides, the sliding block 22 moves, which will cause the wire rope 24 to move and the rotating wheel 23 to rotate under the action of friction. At this time, the tension of the wire rope 24 on the pressure plate 25 will be weakened, because the spring 26 is in a compressed state, and the pressure plate 25 will squeeze the soil at the bottom of the support seat 1 under the elastic force of the spring 26, thereby improving the density of the soil around the support seat 1; when the sliding plate 16 moves, the sliding block 22 will move with the wire rope 24, and the pressure plate 25 will squeeze the soil at the bottom of the support seat 1 under the elastic force of the spring 26, thereby reducing the pores inside the soil around the support seat 1, thereby improving the bearing capacity of the soil on the device and enhancing the stability of the device when reinforcing the foundation pit.
[0028] See also Figure 3 As shown, a plurality of protrusions 3 are fixedly connected to the bottom of the pressing plate 25; the protrusions 3 are arranged in an array; when the pressing plate 25 squeezes the soil under the elastic force of the spring 26, the protrusions 3 will also squeeze the soil together with the pressing plate 25. Because the ends of the protrusions 3 are sharp, the protrusions 3 will be inserted into the soil, thereby enhancing the squeezing effect of the pressing plate 25 on the soil and further increasing the pulling effect between the device and the soil.
[0029] See also Figure 1 and Figure 4 As shown, a plurality of steel pipes 4 are fixedly connected to the middle of the steel plate 12; a plurality of first circular holes 42 are opened in the middle of the steel pipe 4; when the steel plate 12 approaches the slope of the foundation pit, the steel pipe 4 will also move with the steel plate 12, and when the steel pipe 4 moves, it will enter the interior of the foundation pit soil and drill holes in the foundation pit. At this time, the staff can perform grouting treatment in the steel pipe 4, and the cement slurry will flow out from the first circular hole 42 after entering the interior of the steel pipe 4, thereby realizing the grouting treatment of the interior of the foundation pit by the device, and further improving the stability of the soil inside the foundation pit.
[0030] See also Figure 4 and Figure 5As shown, a plurality of baffles 5 are fixedly connected to the middle of the steel pipe 4; the baffles 5 and the first circular holes 42 are correspondingly arranged; iron wires 52 are fixedly connected between adjacent baffles 5; when the steel pipe 4 is drilled into the soil of the foundation pit, soil will move along the surface of the steel pipe 4, and the soil will come into contact with the baffles 5 and be intercepted by the baffles 5, thereby reducing the soil blocks entering the steel pipe 4. Meanwhile, when larger soil blocks come into contact with the iron wires 52, they will be cut by the iron wires 52, thereby reducing the resistance encountered by the steel pipe 4 when drilling into the soil.
[0031] See also Figure 5 As shown, a sphere 6 is fixedly connected to the middle of the baffle 5; a plurality of second circular holes 62 are opened in the middle of the sphere 6; cement slurry will be sprayed out from the first circular hole 42 inside the steel pipe 4, and then the cement slurry will reach the surface of the baffle 5 and enter the inside of the sphere 6, and finally the cement slurry will be sprayed out from the second circular hole 62, thereby increasing the flow range of the cement slurry and accelerating the speed of the device in grouting the foundation pit.
[0032] See also Figure 4 As shown, a cutter 7 is fixedly connected to the end of the steel pipe 4; the cutter 7 is a cross-shaped structure; when the steel pipe 4 is drilled into the soil of the foundation pit, the cutter 7 will come into contact with the soil before the steel pipe 4, and the cutter 7 will cut the soil blocks inside the foundation pit, thereby reducing the resistance encountered by the steel pipe 4 when moving, and reducing the damage to the steel pipe 4 caused by collision with the soil blocks.
[0033] Working principle: the staff moves the device to the edge of the foundation pit and starts the device. After the device is started, the motor 14 is started and the screw 15 is rotated. When the screw 15 rotates, the slide plate 16 will move along the screw 15 due to the threaded connection. When the slide plate 16 moves, it will move with the first connecting rod 17 and change the angle of the first connecting rod 17. When the first connecting rod 17 moves, it will exert pressure on the steel plate 12 and change the angle of the steel plate 12. Under the pressure of the first connecting rod 17, the steel plate 12 will approach the foundation pit slope until it contacts the edge of the foundation pit. When the steel plate 12 contacts the foundation pit slope, it will press the soil layer inside the foundation pit. When the slide plate 16 moves, it will also move with the second connecting rod 2. When the second connecting rod 2 moves, the angle will change and exert a pulling force on the slider 22, so that the slider 22 will slide along the vertical plate 13. When the slider 22 moves, it will move the wire rope 24 and make the rotating wheel 23 rotate under the action of friction. At this time, the pulling force of the wire rope 24 on the pressure plate 25 will be weakened because the spring 26 is in a compressed state. The pressure plate 25 will squeeze the soil at the bottom of the support seat 1 under the elastic force of the spring 26 to improve the density of the soil around the support seat 1. When the pressure plate 25 is under the elastic force of the spring 26 When the soil is squeezed downward, the protrusion 3 will also squeeze the soil together with the pressure plate 25. Because the end of the protrusion 3 is sharp, the protrusion 3 will be inserted into the soil, thereby enhancing the squeezing effect of the pressure plate 25 on the soil; when the steel plate 12 approaches the slope of the foundation pit, the steel pipe 4 will also move with the steel plate 12. When the steel pipe 4 moves, it will enter the interior of the foundation pit soil and drill holes in the foundation pit. At this time, the staff can perform grouting treatment in the steel pipe 4. After the cement slurry enters the interior of the steel pipe 4, it will flow out from the first circular hole 42, thereby realizing the grouting treatment of the interior of the foundation pit by the device; when the steel pipe 4 drills into the interior of the foundation pit soil, soil will move along the surface of the steel pipe 4. , these soils will come into contact with the baffle 5 and be intercepted by the baffle 5, reducing the soil blocks entering the steel pipe 4. At the same time, larger soil blocks will be cut by the iron wire 52 when they come into contact with the iron wire 52, reducing the resistance encountered by the steel pipe 4 when drilling into the soil; cement slurry will be sprayed out from the first circular hole 42 inside the steel pipe 4, and then the cement slurry will reach the surface of the baffle 5 and enter the inside of the ball 6, and finally the cement slurry will be sprayed out from the second circular hole 62, increasing the flow range of the cement slurry; when the steel pipe 4 drills into the soil of the foundation pit, the tool 7 will come into contact with the soil before the steel pipe 4, and the tool 7 will cut the soil blocks inside the foundation pit, reducing the resistance encountered by the steel pipe 4 when it moves.
