[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: an underground anti-seepage wall slot casting construction device, including a connecting column 2, three concave grooves 7 are opened on the outside of the connecting column 2, and a rack 3 is slidably connected to the inner wall of the concave groove 7, and three limit blocks 10 are fixedly connected to the inner wall of the connecting column 2, and the outer rotation of the limit block 10 is connected to a connecting rod 13, and the top of the connecting rod 13 is fixedly connected to a gear 9, and the bottom of one of the limit blocks 10 is fixedly connected to a motor 11, and an installation groove 22 is opened on the inner wall of the connecting column 2, and a gear ring 8 is slidably connected to the inner wall of the installation groove 22, and a grouting pipe 5 is slidably connected to the outside of the connecting column 2, and the outside of the grouting pipe 5 is fixedly connected to a fixed block 12, and two card slots 6 are opened on the outside of the fixed block 12, and a disassembly component is installed inside the connecting column 2.

[0031] Furthermore, the motor 11 is started first, and the output end of the motor 11 drives the connecting rod 13 to rotate, and then drives one of the gears 9 to rotate, and the gear 9 drives the ring gear 8 to rotate synchronously. Under the action of the ring gear 8, the other two gears 9 are driven to rotate, and then the gear 9 drives the rack 3 to move simultaneously along the inner wall of the concave groove 7, so that the sliding wheel contacts the inner wall of the bored pile 1, thereby fixing the grouting pipe 5, so that the grouting pipe 5 remains vertical during the grouting process. The grouting pipe 5 is fixed in a suitable position to ensure that it remains stable during the construction process, and avoids affecting the accuracy and quality of grouting due to movement or shaking. The function of the sliding wheel is to make the grouting pipe 5 smoother during the rising or falling process, thereby reducing safety hazards at the construction site.

[0032] Reference Figure 1 and Figure 4 The disassembly assembly includes two pull rods 4, the outer side of the pull rods 4 is slidably connected to the outside of the connecting column 2, one end of the pull rod 4 is fixedly connected to a baffle 14, the outer side of the baffle 14 is fixedly connected to a moving rod 18, the outer side of the moving rod 18 is sleeved with a spring 15, a slide groove 16 is provided inside the connecting column 2, an inner side wall of the slide groove 16 is provided with an internal groove 21, the inner wall of the internal groove 21 is fixedly connected to a spring 20, the other end of the spring 20 is fixedly connected to a block 17, and the outer side of the block 17 is fixedly connected to a triangular block 19.

[0033] Furthermore, when it is necessary to disassemble the connecting column 2, by pressing the pull rod 4 downward, the pull rod 4 drives the baffle 14 to move along the inner wall of the slide groove 16, and then drives the moving rod 18 to move downward synchronously. At the same time, the moving rod 18 pushes the triangular block 19 to move to one side. Under the action of the triangular block 19, the block 17 moves along the inner wall of the internal groove 21 until the block 17 is completely retracted into the interior of the internal groove 21. At this time, the spring 20 is in a compressed state, and the connecting column 2 is further separated from the grouting pipe 5, completing the disassembly of the connecting column 2. To install the connecting column 2, press the pull rod 4 downwards and repeat the above steps. At this time, the spring 20 is in a compressed state. Release the pull rod 4. Under the elastic force of the spring 15, the baffle 14 is reset, and the baffle 14 drives the moving rod 18 to move synchronously. Then, under the elastic force of the spring 20, the block 17 is inserted into the inside of the slot 6 to complete the installation of the connecting column 2. By installing and disassembling the connecting column 2, workers can quickly adjust or replace parts as needed without spending too much time and energy, thereby improving construction efficiency.

[0034] Reference Figure 2 and Figure 3 The outer side of the gear 9 is meshed and connected with the outer side of the ring gear 8 , and the outer side of the gear 9 is meshed and connected with the outer side of the rack 3 .

[0035] Furthermore, the gear ring 8 is driven to rotate by the gear 9, and the gear 9 drives the rack 3 to move synchronously.

[0036] Reference Figure 4 The longitudinal section of the baffle 14 is square, and the outside of the baffle 14 is slidably connected to the inner wall of the chute 16.

[0037] Furthermore, the baffle 14 is moved along the inner wall of the slide groove 16 , which effectively prevents the baffle 14 from shaking during the movement, thereby improving the stability of the baffle 14 .

[0038] Reference Figure 4 The shape of the card block 17 matches the card slot 6, and the card block 17 and the card slot 6 are plug-fitted.

[0039] Furthermore, by snapping the snap block 17 into the snap slot 6, the connection column 2 is made more stable, which further ensures the accuracy of the grouting pipe 5 during grouting and improves the grouting effect.

[0040] Reference Figure 1 , Figure 2 and Figure 3 One end of the rack 3 is rotatably connected to a sliding wheel, and the outer side of the sliding wheel is slidably connected to a cast-in-place pile 1.

[0041] Furthermore, the function of the sliding wheel is to make the grouting pipe 5 smoother during the rising or falling process, reduce the potential safety hazards at the construction site, and improve the construction efficiency.

[0042] Reference Figure 4 The pull rod 4 passes through the connecting column 2 and extends to the outside, and the top of the pull rod 4 is provided with anti-slip grooves.

[0043] Furthermore, it is convenient for construction workers to press the pull rod 4 to disassemble or install the connecting column 2. The anti-slip pattern increases the friction of the pull rod 4 and reduces the risk of accidental slip or loss of control of the construction workers' hands.

[0044] Reference Figure 4 One end of the spring 15 is fixedly connected to the outer side of the baffle 14 , and the other end of the spring 15 is fixedly connected to the inner wall of the slide groove 16 .

[0045] Furthermore, the baffle 14 is fixed to prevent the baffle 14 from sliding freely along the inner wall of the slide groove 16 . At the same time, under the elastic force of the spring 15 , the baffle 14 can be quickly reset.

[0046] Working principle: When using this device, first start the motor 11, and the output end of the motor 11 drives the connecting rod 13 to rotate, which in turn drives one of the gears 9 to rotate, and then drives the ring gear 8 to rotate. Further, the ring gear 8 drives the other two gears 9 to rotate. At the same time, the gear 9 drives the rack 3 to move outward at the same time, and further the sliding wheel contacts the inner wall of the bored pile 1, thereby fixing the grouting pipe 5, so that the grouting pipe 5 remains vertical during the grouting process. By fixing the grouting pipe 5, it can be ensured that it maintains the correct grouting direction, so that the grouting material can be accurately filled into the target position, thereby improving the grouting effect. The function of the sliding wheel is to make the grouting pipe 5 smoother during the rising or falling process, thereby reducing safety hazards at the construction site.

[0047] In addition, when it is necessary to disassemble the connecting column 2, by pressing the pull rod 4 downward, the pull rod 4 drives the baffle 14 to move, and then drives the moving rod 18 to move synchronously. At the same time, the moving rod 18 pushes the triangular block 19 to move to one side, and drives the block 17 to move through the triangular block 19 until the block 17 is completely retracted into the interior of the internal groove 21, further separating the connecting column 2 from the grouting pipe 5, and completing the disassembly of the connecting column 2. When it is necessary to install the connecting column 2, press the pull rod 4 downward and repeat the above steps. At this time, the spring 20 is in a compressed state, and the pull rod 4 is released. Then, under the elastic force of the spring 20, the block 17 is stuck into the interior of the slot 6 to complete the installation of the connecting column 2. By installing and disassembling the connecting column 2, the flexibility of the connecting column 2 is enhanced, so that it can adapt to different construction needs and changing engineering conditions.
