[0001] The invention relates to the technical field of cast-in-place pile construction, and in particular to an anti-overflow cast-in-place pile construction device. Background Art

[0002] A bored pile is a type of pile that is made by drilling a hole directly on the pile site and then pouring concrete or reinforced concrete into the hole. Depending on the hole-forming method, it can be divided into bored cast-in-place piles, sunk tube cast-in-place piles, manually excavated cast-in-place piles, etc. Bored cast-in-place piles are widely used in the field of construction engineering due to their low cost and simple construction operation.

[0003] At present, when using a bored pile construction device, there is a lack of an auxiliary overflow prevention and recovery mechanism. Usually, when paying attention to the concrete in the pile hole, due to the excessively fast pouring speed, the pouring stop operation is not timely, and it is difficult to observe the amount of concrete in the pile hole, resulting in concrete overflowing from the top of the casing, causing a waste of resources. Therefore, an overflow prevention bored pile construction device is proposed to facilitate the addition of an auxiliary overflow prevention and recovery mechanism, and the overflowed concrete is recycled and processed by means of peripheral sleeve, diversion and recovery, thereby reducing resource waste, improving environmental pollution, and improving the use effect.

[0030] In order to facilitate the recycling of overflowed concrete, reduce resource waste, improve environmental pollution, and thus improve the use effect, such as Figure 1-3 As shown, an anti-overflow cast-in-place pile construction device of the present invention comprises a casing 1, a sheath 3 and a guide assembly 5, wherein the outer periphery of the casing 1 is provided with a base 2, the inner side of the base 2 is located at the outer periphery of the casing 1 and a sheath 3 for auxiliary protection is vertically provided, the top of the base 2 is located at the outer periphery of the sheath 3 and a recovery assembly 4 for recovery is vertically provided, and the inner surface of the sheath 3 is provided with a guide assembly 5;

[0031] A conical guide groove 301 is provided in the sleeve 3, and the guide assembly 5 includes a guide bracket 501, and the guide bracket 501 is connected to the conical guide groove 301 by bolts. A guide groove 502 is provided in the guide bracket 501, and a ball groove 503 is provided on the outer surface of the guide bracket 501, and a ball 504 is rollingly connected in the ball groove 503.

[0032] When in use, an auxiliary anti-overflow recovery mechanism can be added through the base 2, the sleeve 3, the conical guide groove 301, the guide bracket 501, the guide groove 502, the ball groove 503 and the ball 504. The concrete generated by the overflow of the pouring operation is recycled by means of socketing, reinforcement, diversion and recovery. This can not only reduce resource waste, reduce construction costs, and improve the working environment, but also play an auxiliary guiding correction effect, thereby improving the flexibility and convenience of the construction operation of the hoisting steel cage. It has a simple structure, low cost, and is more reasonable and reliable to use.

[0033] For example, Figure 1 , Figure 2 As shown, the present invention also includes that the periphery of the guide bracket 501 is located on the surface of the conical guide groove 301 and is connected to a positioning sleeve 505 by welding, one end of the guide bracket 501 is connected to a guide pipe 506 by welding, and one end of the guide pipe 506 passes through the sheath 3 and connects to the recovery component 4.

[0034] When in use, the positioning sleeve 505 can improve the stability of the diversion bracket 501 and reinforce it to reduce the impact of extrusion during the guidance of the steel cage. The diversion pipe 506 can facilitate the recovery of concrete in the diversion groove 502 to be introduced into the recovery component 4 for storage and recycling.

[0035] For example, Figure 4 As shown, the present invention also includes that the recovery component 4 includes a recovery box 401, and the base 2 is connected to the recovery box 401 by bolts, a recovery groove 402 is opened in the recovery box 401, and a movable groove 403 is opened in the recovery box 401 at the bottom of the recovery groove 402, a horizontally arranged push rod 404 is sleeved and connected in the movable groove 403, and the push rod 404 passes through the reserved hole. The end of the push rod 404 is connected to an arc-shaped clamping plate 405 corresponding to the casing 1 by welding.

[0036] When in use, a diversion recovery storage mechanism can be formed through the recovery box 401 and the recovery groove 402, and the overflow is directed to the recovered concrete for temporary storage treatment. Through the movable groove 403, the push rod 404 and the arc-shaped clamping plate 405, the recovered concrete can be used to push the push rod 404 to slide to both sides of the casing 1, so that the arc-shaped clamping plate 405 clamps the casing 1 and performs auxiliary reinforcement and sealing treatment on it, thereby improving the working stability of the casing 1, and at the same time, it can also reduce the gap between the casing 1 and the jacket 3, further improve the overflow situation, thereby reducing resource waste and reducing construction costs.

[0037] For example, Figure 4 As shown, the present invention also includes that the surface of the arc-shaped clamping plate 405 is connected with an anti-slip pad 406 by gluing, a piston 407 is vertically arranged in the movable groove 403 at the other end of the push rod 404, a return spring 408 is sleeved on the outer periphery of the push rod 404 in the movable groove 403, a feed pump 409 is arranged between the recovery groove 402 and the movable groove 403, and the output end of the feed pump 409 is connected to the movable groove 403 through a pipeline.

[0038] When in use, the anti-slip pad 406 is used to improve the sealing quality and effect of the arc-shaped clamping plate 405. Through the piston 407 and the return spring 408, the elastic force is used to drive the push rod 404 to perform a reset, sliding and retracting action, and at the same time, the concrete in the movable groove 403 is pushed out to complete the automatic auxiliary discharge action. Through the feed pump 409, the concrete recovered by diversion in the recovery groove 402 can be pumped into the movable groove 403, pushing the push rod 404 to perform a clamping and reinforcement action, which can not only increase the use effect of the device, but also increase the overflow recovery space.

[0039] For example, Figure 4 As shown, the present invention also includes that a discharge port 410 is provided on the outer surface of the recovery box 401, and the discharge port 410 is connected to the recovery tank 402, a second discharge port 411 is provided on the outer surface of the recovery box 401 at the bottom of the discharge port 410, and the second discharge port 411 is connected to the movable tank 403, and a liquid level sensor 412 is vertically arranged in the recovery tank 402.

[0040] When in use, the concrete stored in the recovery tank 402 and the movable tank 403 can be sent out through the discharge port 410 and the second discharge port 411 after the device is used, so as to facilitate subsequent recycling and reuse. The liquid level sensor 412 can be used to monitor the amount of concrete overflowed and recovered in the recovery tank 402. Sealing plugs are provided in the discharge port 410 and the second discharge port 411.

[0041] For example, Figure 2As shown, the present invention also includes that an inner groove 302 is formed at the bottom of the sheath 3 , and the inner groove 302 is sleeved and connected to the arc-shaped clamping plate 405 .

[0042] When in use, the inner groove 302 facilitates the movement of the arc-shaped clamping plate 405 to clamp, reinforce and seal the casing 1 .

[0043] For example, Figure 1 As shown, the present invention also includes that the peripheries of the base 2 and the sheath 3 are both sleeved with a clamp 6 , and the clamp 6 includes a fixing bolt 601 .

[0044] When in use, the base 2 and the sheath 3 are conveniently spliced ​​together by the clamp 6 and then clamped and limited to fix, thereby improving the stability of the device during assembly and use.

[0045] When the present invention is used, first, after the construction personnel drill the pile hole at the designated bored pile position by means of an auger, they insert the casing 1 into the pile hole for fixing, then move the base 2 to the top of the pile hole, screw in the fixing bolts 601, and use the clamp 6 to clamp and fix the base 2 and the jacket 3 in turn, then use the ground nails and hammering equipment to limit and fix the base 2, then the construction personnel use the lifting equipment to send the steel cage from the top of the pile hole through the jacket 3 into the pile hole, in the process of lifting the steel cage construction, the guide bracket 501 of the guide and diversion assembly 5 can play the function of assisting the guide correction, and the ball groove 503 and the ball 504 can reduce the friction generated with the steel cage, thereby improving the stability of the guide, and also facilitating the extension of the service life of the guide bracket 501;

[0046] Then, the casing 1 is manually lifted by the hoisting equipment and the concrete is manually poured into the casing 1 of the pile hole through the conical guide groove 301 of the casing 3 by the pouring equipment. When the concrete overflows the casing 1, the concrete flows into the conical guide groove 301, and the overflowing concrete is guided to the recovery groove 402 in the recovery box 401 through the guide groove 502 of the guide bracket 501 for recycling. At the same time, the state in the recovery groove 402 is monitored by the liquid level sensor 412, so as to stop the pouring construction in time, thereby avoiding the overflow of concrete to pollute the working environment, reducing resource waste and construction costs, and having a simple structure and easy operation, and being more reasonable and reliable to use, and greatly improving the working environment of the construction;

[0047] Moreover, the feeding pump 409 can be manually started at the same time, and the feeding pump 409 is used to pump the overflowed concrete in the recovery tank 402 into the movable tank 403, and the injected concrete is used to push the push rod 404 to slide toward the outside of the casing 1, so that the arc clamping plate 405 clamps and fixes the casing 1, thereby realizing an auxiliary reinforcement structure, improving the working stability of the casing 1, and reducing the gap between the casing 1 and the jacket 3, further improving the overflow situation, with a simple structure, low cost, more reasonable and reliable use, and further improving the quality of the construction working environment, reducing resource waste, and reducing construction costs;

[0048] Finally, when the recovered concrete needs to be discharged, the sealing plugs of the discharge port 410 and the second discharge port 411 are opened, so that the automatic discharge device of the recovered concrete in the recovery tank 402 can complete the recovery. At the same time, under the push of the elastic force of the reset spring 408, the piston 407 and the push rod 404 can be driven to slide toward the inside of the movable tank 403 for reset action, so that the concrete in the movable tank 403 is pushed out for subsequent reuse. The operation is simple and convenient, and the use is faster and more reliable.
