Anti-slide pile belt mold construction device

Abstract

This invention discloses a formwork construction device for anti-slip piles, relating to the field of anti-slip pile construction. It includes a base frame, with load-bearing piles fixedly connected to the top of the base frame and near its four inner corners. A filling structure is provided on the top of the base frame, comprising four rotating plates, each located on one of the four inner edges of the top of the base frame. Hollow bladders are fixedly connected to the inner walls of each of the four rotating plates, and input pipes are fixedly connected through the tops of the four hollow bladders. Connecting pipes are fixedly connected between the four input pipes. This invention significantly reduces demolding resistance and the difficulty of removing the device by utilizing the gaps formed after the medium is emptied from the hollow bladders and a specially designed isolation membrane. After the pile solidifies, the medium inside the hollow bladders is emptied, causing them to shrink. Simultaneously, the anti-adhesion effect of the polytetrafluoroethylene (PTFE) isolation membrane creates a separation gap between the pile surface and the hollow bladders and rotating plates, greatly reducing adhesion and allowing the entire device to easily detach from the formed pile.

Description

Technical Field

[0001] This invention relates to the field of anti-slide pile construction, and in particular to an anti-slide pile formwork construction device. Background Technology

[0002] The anti-slide pile formwork construction device is a piece of equipment used for anti-slide pile construction in slope landslide control. It mainly consists of a formwork system that can form a pile pouring space, a support system, a positioning system, and concrete pouring auxiliary devices. It features high construction efficiency, stable pile quality, and strong safety. Through modular design and standardized assembly, it is suitable for anti-slide pile construction under different geological conditions and pile diameter specifications, and can effectively improve the reliability and economy of slope engineering. Existing construction equipment requires high-intensity manual labor during formwork removal due to severe concrete adhesion, which is inefficient and easily damages the pile surface. At the same time, the curing process lacks automation and relies on delayed manual watering, which can easily cause shrinkage cracks. In addition, existing construction equipment uses fixed formwork, which has poor turnover and often becomes deformed and unusable after removal, increasing material costs and wasting resources. Summary of the Invention

[0003] The main objective of this invention is to provide an anti-slide pile formwork construction device, which can significantly reduce the demolding resistance and the difficulty of removing the device.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A formwork construction device for anti-slide piles includes a base frame. Load-bearing piles are fixedly connected to the top of the base frame and to its four inner corners. A filling structure is provided on the top of the base frame, comprising four rotating plates. Each rotating plate is located on one of the four inner edges of the top of the base frame. Hollow bladders are fixedly connected to the inner walls of each of the four rotating plates. Input pipes are fixedly connected to the tops of the four hollow bladders, penetrating their interiors. Connecting pipes are fixedly connected between the four input pipes.

[0005] As a further embodiment of the present invention, each of the four hollow bladders has a pair of valve ports connected to its top, with the pair of valve ports located on both sides of the input tube.

[0006] As a further embodiment of the present invention, an isolation membrane is fixedly connected to the inner side of each of the four hollow bladders.

[0007] As a further aspect of the present invention, several elastic valve membranes are fixedly connected to the inner side of the hollow bladder through the isolation membrane, and the elastic valve membranes have cross grooves on their sides.

[0008] As a further embodiment of the present invention, rotating blocks are fixedly connected to both sides of the rotating plate near the top, and the rotating plate is rotatably connected to two adjacent load-bearing piles through the two rotating blocks.

[0009] As a further embodiment of the present invention, a demolding structure is provided on the outer side of the four rotating plates. The demolding structure includes four connecting plates. A load-bearing plate is fixedly connected to the top of the base frame along the four outer edges. A pair of top blocks are fixedly connected to the inner side of the load-bearing plate near the top. A connecting shaft is fixedly connected between the pair of top blocks. Two electric push rods are rotatably connected to the outer surface of the connecting shaft. A pair of sliding grooves are provided on the inner side of the load-bearing plate. A slider is slidably connected inside the two sliding grooves. A sliding shaft is fixedly connected between the two sliders. A pair of bottom blocks are fixedly connected to the outer side of the rotating plates.

[0010] As a further embodiment of the present invention, the top of the connecting plate is rotatably connected to the sliding shaft, and the bottom of the connecting plate is rotatably connected to a pair of bottom blocks.

[0011] As a further embodiment of the present invention, the connecting plate is arranged in an inclined state.

[0012] As a further embodiment of the present invention, the slider is located in the middle of the groove.

[0013] As a further embodiment of the present invention, the output shaft of the electric actuator is rotatably connected to the sliding shaft, and the stroke of the output shaft of the electric actuator is at half position.

[0014] The above embodiments of the present invention can achieve the following beneficial effects: by using a hollow bladder that can be filled with a medium in conjunction with a rotating plate structure, the shape of the formed anti-slide pile can be effectively constrained. During the concrete pouring stage, water or air is injected into the hollow bladder to make it expand and tightly fill the gap between the steel cage and the rotating plate, ensuring that the anti-slide pile forms the standard geometric shape required. The gaps formed by emptying the medium in the hollow bladder and the special isolation membrane significantly reduce demolding resistance and the difficulty of removing the device. After the pile solidifies, the medium in the hollow bladder is emptied to cause it to shrink. At the same time, under the anti-sticking effect of the isolation membrane made of polytetrafluoroethylene, a separation gap is formed between the pile surface and the hollow bladder and the rotating plate, which greatly reduces adhesion and allows the whole device to be easily separated from the molded pile. The design of the elastic valve membrane provides a controllable water curing function for the pile surface. When water is used as the filling medium, continued pressurization can force the water to break through the elastic valve membrane inside the hollow bladder and penetrate into the newly formed anti-slide pile surface to automatically wet and cure it, which helps to prevent early cracking of concrete. The demolding structure drives the rotating plate to rotate, achieving efficient and fast demolding operation. The electric push rod in the demolding structure can drive the connecting plate and sliding shaft to move, thereby forcibly driving the rotating plate to rotate inward or outward. Rotating inward can actively squeeze the hollow bladder to accelerate its emptying, while rotating outward can directly separate the rotating plate and hollow bladder from the pile body and expand the gap, greatly improving the efficiency of demolding and device removal. Through the linkage mechanical structure design, the synchronization and controllability of the demolding action are ensured, improving operational reliability and reducing the risk of equipment damage. The electric push rod, sliding shaft, connecting plate, slider and slide groove in the demolding structure work together to accurately convert the linear motion of the electric push rod into the rotational motion of the rotating plate. This linkage design not only ensures the coordinated action of the four rotating plates and avoids uneven load or jamming, but also effectively controls the rotation angle of the rotating plate and the degree of compression of the hollow bladder by limiting the stroke of the slider through the slide groove, making the whole demolding process more stable and controllable, and reducing the possibility of equipment damage due to improper operation. By limiting the extension and retraction of the output shaft of the electric actuator, the rotation angle of the connecting plate is limited, thereby preventing the connecting plate from being squeezed and collided with the load-bearing plate or anti-slip pile due to excessive rotation.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-5As shown, an anti-slide pile formwork construction device includes a base frame 1. Load-bearing piles 3 are fixedly connected to the top of the base frame 1 and to the four inner corners. A filling structure 2 is provided on the top of the base frame 1. The filling structure 2 includes four rotating plates 4. The four rotating plates 4 are respectively set on the top of the base frame 1 to the four inner edges. Hollow bladders 5 are fixedly connected to the inner walls of the four rotating plates 4. Input pipes 6 are fixedly connected through the top of the four hollow bladders 5. Connecting pipes 7 are fixedly connected between the four input pipes 6. In actual operation, when installing the device, first, the anti-slip pile steel cage is installed in the anti-slip pile foundation pit. Then, the base frame 1 along with the entire device is also placed in the anti-slip pile foundation pit, with the steel cage located inside the four rotating plates 4. At this time, concrete is injected into the steel cage. At the same time, the top of the connecting pipe 7 is opened, and water or air is injected into the four input pipes 6 through the connecting pipe 7, thereby filling the hollow bladder 5. The hollow bladder 5 fills the gap between the rotating plate 4 and the newly formed anti-slip pile. The shape of the anti-slip pile is restricted by the four hollow bladders 5. Specifically, after the anti-slip pile solidifies, the two valve ports 8 at the top of each hollow bladder 5 are opened to drain the air or water inside the hollow bladder 5. At this time, a gap exists between the solidified anti-slip pile and the rotating plate 4. Therefore, the anti-slip pile is only connected to the hollow bladder 5, so the construction device can be easily separated from the anti-slip pile, making it easy to remove the construction device.

[0019] Each of the four hollow bladders 5 has a pair of valve ports 8 connected to its top. The pair of valve ports 8 are located on both sides of the input pipe 6. The filling medium inside the hollow bladders 5 can be discharged through the valve ports 8, causing the hollow bladders 5 to contract.

[0020] The inner sides of the four hollow bladders 5 are all fixedly connected with an isolation membrane 9. The isolation membrane 9 is made of polytetrafluoroethylene (PTFE) and has the property of not sticking to concrete. Therefore, the isolation membrane 9 also prevents the hollow bladders 5 from sticking to the anti-slip piles, thus further reducing the difficulty of removing the construction device.

[0021] Several elastic valve membranes 10 are fixedly connected to the inner side of the hollow bladder 5 through the isolation membrane 9. The elastic valve membrane 10 has a cross groove on its side. The elastic valve membrane 10 is elastic. When the internal pressure of the hollow bladder 5 is greater than the breaking pressure of the elastic valve membrane 10, the elastic valve membrane 10 breaks and the cross groove opens. When the internal pressure of the hollow bladder 5 returns to normal, the elastic valve membrane 10 resets and the cross groove closes. When water is injected into the hollow bladder 5, the internal pressure of the hollow bladder 5 can be increased to the critical pressure for the elastic valve diaphragm 10 to rupture. This causes the elastic valve diaphragm 10 to open along the cross groove, allowing the water inside the hollow bladder 5 to flow onto the surface of the anti-slip pile. This moistens the anti-slip pile and prevents it from cracking during the drying process. When the internal pressure of the hollow bladder 5 is less than the critical pressure for the elastic valve diaphragm 10 to rupture, the elastic valve diaphragm 10 returns to its original position, and the cross groove closes.

[0022] Rotating blocks 11 are fixedly connected to both sides of the rotating plate 4 near the top. The rotating plate 4 is rotatably connected to the two adjacent load-bearing piles 3 through the two rotating blocks 11.

[0023] The outer sides of the four rotating plates 4 are provided with demolding structures 12, which include four connecting plates 20. The top of the base frame 1 is fixedly connected to the four outer edges of the outer ring with load-bearing plates 13. The inner side of the load-bearing plates 13 is fixedly connected to the top of the top edge with a pair of top blocks 14. The pair of top blocks 14 are fixedly connected to a connecting shaft 15. The outer surface of the connecting shaft 15 is rotatably connected to two electric push rods 16. The inner side of the load-bearing plates 13 is provided with a pair of sliding grooves 17. The interior of the two sliding grooves 17 is slidably connected to sliders 18. The two sliders 18 are fixedly connected to a sliding shaft 19. The outer side of the rotating plates 4 is fixedly connected to a pair of bottom blocks 21. Specifically, the demolding structure 12 is operated and all valve ports 8 are opened. When the output shaft of the electric actuator 16 extends, it drives the four sliding shafts 19 to move down, thereby driving all the sliders 18 to slide down along all the sliding grooves 17 until the sliders 18 are at the bottom of the sliding grooves 17. At this time, the output shaft of the electric actuator 16 is in the maximum extension state. During the downward movement of the sliding shafts 19, the connecting plate 20 will move down together. However, since the bottom of the connecting plate 20 is rotatably connected to the two bottom blocks 21, the sliding shafts 19 will drive the rotating plate 4 to rotate along the inner side of the rotating plate 4 through the connecting plate 20 while sliding down. This causes the hollow bladder 5 filled with water or air to be squeezed against the outer surface of the anti-slip pile, so that the water or air inside the hollow bladder 5 can be quickly discharged from the valve port 8, accelerating the contraction speed of the hollow bladder 5, thus speeding up the removal efficiency of its construction device. When the output shaft of the electric actuator 16 retracts, it drives the four sliding shafts 19 to move upward until the slider 18 is at the top of the slide groove 17. At this time, the output shaft of the electric actuator 16 is in the maximum retracted state. During the upward movement of the sliding shafts 19, the connecting plate 20 drives the rotating plate 4 to rotate along the outer direction of the rotating plate 4, thereby causing the hollow bladder 5 to rotate together. Therefore, the hollow bladder 5 can be separated from the anti-slip pile in advance, and the distance between the rotating plate 4 and the anti-slip pile is further increased, thereby further reducing the difficulty of removing the construction device.

[0024] The top of the connecting plate 20 is rotatably connected to the sliding shaft 19, and the bottom of the connecting plate 20 is rotatably connected to a pair of bottom blocks 21. The pair of bottom blocks 21 are used to restrict the bottom of the connecting plate 20, thereby converting the vertical sliding force of the sliding shaft 19 into the rotational force of the connecting plate 20.

[0025] The connecting plate 20 is set in an inclined state. In its initial state, the connecting plate 20 is inclined, so when the connecting plate 20 is subjected to vertical upward or downward force, it can rotate along the rotational connection point with the slide shaft 19 and the base block 21. This maximizes the utilization of the vertical stroke of the slide shaft 19 and efficiently converts it into the rotation angle of the rotating plate 4. When the slide shaft 19 moves downward, the connecting plate 20, under the action of vertical force, rotates inward along the inclined direction with the rotational connection point between its bottom and the base block 21 as the fulcrum, and vice versa.

[0026] The slider 18 is located in the middle of the groove 17. In the initial state, the slider 18 is located in the middle of the groove 17. At this time, the connecting plate 20 is in an inclined and static state. Therefore, the rotating plate 4 is in a vertical state. At this time, the rotating plate 4 acts as a template, so that the poured concrete can solidify along the square pile.

[0027] The output shaft of the electric actuator 16 is rotatably connected to the sliding shaft 19, and the stroke of the output shaft of the electric actuator 16 is at half position. When the output shaft of the electric actuator 16 retracts to its minimum length, the connecting plate 20 and the rotating plate 4 are at the maximum outward rotation angle. When the output shaft of the electric actuator 16 extends to its maximum length, the connecting plate 20 and the rotating plate 4 are at the maximum inward rotation angle. By limiting the extension and retraction process of the output shaft of the electric actuator 16, the rotation angle of the connecting plate 20 is limited, thereby avoiding the situation where the connecting plate 20 is squeezed and collided with the load-bearing plate 13 or the anti-slip pile due to excessive rotation.
