Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a hydraulic soil compaction device for cleaning the core of pipe piles. Background Technology

[0002] High-strength prestressed concrete pipe piles are widely used in building foundation construction. These piles are generally constructed using hammer driving or static pile driving methods. When the bottom of the pipe pile is not equipped with a tapered pile tip, the soil around the pipe pile will be compacted during the pile formation process, and the soil inside the ground often blocks the core hole of the pipe pile. Before the construction of the basement floor slab, steel bars need to be anchored into the core of the pipe pile and concrete needs to be poured, so the soil inside the core of the pile needs to be cleaned. Manually cleaning the soil inside the precast concrete pipe pile is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a hydraulic soil compaction device for cleaning the core of pipe piles, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A hydraulic soil compaction device for cleaning soil from the core of pipe piles includes pipe piles, reinforcing bars, clamping mechanism, pressing mechanism, water collection mechanism, and aligning mechanism.

[0006] The bottom of the pipe pile is inserted into the foundation pit, and the top of the pipe pile is provided with a reinforcing bar. One end of the reinforcing bar is provided with a clamping mechanism. One side of the clamping mechanism is provided with a pressing mechanism. The top of the pressing mechanism is provided with a water collection mechanism, and the bottom of the pressing mechanism is provided with a regularizing mechanism.

[0007] The clamping mechanism includes a movable clamping plate, one side of which is connected to the pipe pile. A lead screw is provided on one side of the movable clamping plate, a connecting block is provided at one end of the lead screw, and a movable clamp is provided at the end of the lead screw away from the connecting block. A stop spring is provided on one side of the movable clamp, and a baffle is provided at the end of the stop spring away from the movable clamp. The movable clamping plate is fitted and supported against the top of the pipe pile. The position of the connecting block on the lead screw is adjusted by rotating the lead screw. The connecting block moves horizontally along the lead screw to clamp the reinforcing bar at the top of the pipe pile. The connecting block can clamp reinforcing bars of various sizes, improving the applicability of the device. The device can be quickly fixed in position using the reinforcing bar, saving the operator's time and improving the working efficiency of the device.

[0008] One side of the movable clamping plate is connected to the connecting block via a slot, and one side of the baffle is engaged with the movable clamping plate. The bottom of the baffle is connected to the inner wall of the pipe pile. When the lead screw is rotated, it drives the movable clamping block to move synchronously. The movable clamping block compresses the resisting spring, and the compressed spring pushes the baffle horizontally, engaging one side of the baffle with the inner wall of the pipe pile. This improves the fit between the device and the pipe pile, enhancing the stability of the device.

[0009] The pressing mechanism includes a support plate, one side of which is hinged to a movable clamping plate. Several movable clamping plates are arranged equidistantly in a ring around the inner wall of the pipe pile. A hydraulic cylinder is located at the bottom of the support plate, and a bulldozer plate is located at the bottom end of the hydraulic cylinder. A clamping rod is hinged inside the bulldozer plate, and a retaining ring is located at the bottom of the bulldozer plate. The bulldozer plate is conical. By deflecting the movable clamping plate along one side of the support plate, the position of the support plate at the top of the pipe pile is adjusted, regulating the relative position of the bulldozer plate at the bottom of the support plate with respect to the inner wall of the pipe pile, thus improving the precision of the device. Activating the hydraulic cylinder drives the bottom-mounted bulldozer plate to press down, compacting and cleaning the soil at the bottom of the pipe pile core through the conical bulldozer plate, reducing manual labor consumption and lowering construction costs.

[0010] The water collection mechanism includes a water storage tank connected to the upper surface of a supporting plate. A water guide pipe is installed at the top of the water storage tank, with one end connected to a hydraulic cylinder. An inlet network pipe is installed at the bottom of the water guide pipe. The water storage tank is at a higher level than the inlet network pipe. The water guide pipe is U-shaped. Through the inlet network pipe, water is introduced into the water guide pipe, creating a siphon structure that filters the water from the bottom of the pile core through the inlet network pipe before drawing it into the water storage tank. This reduces the impact of accumulated water on the compaction of the soil within the pile core and improves the processing quality of the device.

[0011] The bottom of the bulldozer blade has a through hole, through which the water inlet pipe is connected to the bulldozer blade. The water inlet pipe is engaged with a clamping rod, and its outer wall is connected to a retaining ring. A hydraulic cylinder extends, causing the bulldozer blade to press down. As the bulldozer blade compresses the soil, it also causes the clamping rod to deflect, releasing the clamping rod from the water inlet pipe. The water inlet pipe is then lowered through the through hole at the bottom of the bulldozer blade to the bottom of the compacted pit. The water inlet pipe filters the silt and sand from the accumulated water. Subsequently, as the bulldozer blade is pressed down a second time, the retaining ring scrapes and cleans the outer wall of the water inlet pipe to prevent blockage.

[0012] The regulating mechanism includes a fixed sleeve, the inner wall of which is connected to a hydraulic cylinder. The outer wall of the fixed sleeve has a sliding groove. A movable sleeve is provided on the outer wall of the fixed sleeve. A push rod is provided on the outer wall of the movable sleeve. A movable spring is provided at the top of the push rod. A rotating rod is hinged to the bottom of the push rod. A support rod is provided at the end of the rotating rod away from the push rod. The support rod is arc-shaped. A top rod is provided on one side of the support rod. The top rod is hinged to the top of the bulldozer blade at the end away from the support rod. A rubber sleeve is provided on the side of the support rod away from the top rod. The bottom of the rubber sleeve is connected to the bulldozer blade. As the hydraulic cylinder extends, the top of the bulldozer blade drives the push rod to extend synchronously. The bottom end of the push rod drives the rotating rod to deflect, and the bottom end of the rotating rod drives the top rod to deflect. As the top rod deflects along with the top of the bulldozer blade, it pushes the support rod outward. The support rod stretches the rubber sleeve outward, bringing the rubber sleeve into contact with the inner wall of the pipe pile. After the support rod touches the inner wall of the pipe pile, the top of the push rod squeezes the movable spring, buffering the downward pressure of the hydraulic cylinder. After the rubber sleeve is in contact with the inner wall of the pipe pile, the bulldozer blade continues to press down, pressurizing the bottom of the pipe pile and quickly squeezing the water into the water storage tank. At the same time, the rubber sleeve cleans the inner wall of the pipe pile, reducing the impact of mud and sand adhesion on subsequent construction.

[0013] The movable sleeve is equipped with a positioning spring at its top, and the top of the positioning spring is connected to the support plate. The sliding groove is V-shaped, and several sliding grooves are arranged in a ring around the outer wall of the fixed sleeve. The inner wall of the movable sleeve is provided with protrusions, and the movable sleeve engages with the sliding grooves through these protrusions. Several push rods are provided, and the push rods are evenly distributed in a ring around the outer wall of the movable sleeve. As the hydraulic cylinder extends and retracts, the push rods drive the movable sleeve to slide along the outer wall of the fixed sleeve. When the hydraulic cylinder extends, the push rods drive the movable sleeve downwards, and the protrusions on the inner wall of the movable sleeve move to the bottom of the V-shaped sliding grooves. Subsequently, the hydraulic cylinder retracts, and the movable sleeve compresses the positioning spring. The movable sleeve slides along the sliding grooves through the protrusions on its inner wall, and simultaneously deflects. The movable sleeve drives the push rods and support rods to deflect synchronously, preventing the circumferential gaps in the support rods from causing any omissions in the cleaning of the inner wall of the pipe pile, thus improving the cleaning effect of this device on the inside of the pipe pile.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. The clamping and pressing mechanisms facilitate quick installation by workers. By rotating the screw, the connecting block is clamped and fixed to the reinforcing bar at the top of the pipe pile, which conveniently fixes the position of the pressing mechanism on the pipe pile. Then, the hydraulic cylinder drives the bulldozer plate to compact the soil inside the pipe pile core, reducing the labor consumption of this device and lowering construction costs.

[0016] 2. By setting up clamping, pressing, and aligning mechanisms, the cleanliness of the inner wall of the pipe pile is improved, reducing the impact of soil adhering to the inner wall of the pipe pile on subsequent construction. Through the cooperation of the pressing and aligning mechanisms, the hydraulic cylinder extends and drives the support rod to push the rubber sleeve to expand. The rubber sleeve and the bulldozer plate compact the soil inside the pipe pile, improving the applicability of the device.

[0017] 3. By setting up clamping mechanism, pressing mechanism, water collection mechanism and straightening mechanism, the impact of water accumulation at the bottom of the pipe pile core is reduced and the processing quality of this device is improved. The water collection mechanism absorbs the water accumulation at the bottom of the pipe pile, and then the pressing mechanism and straightening mechanism compact the soil at the bottom of the pipe pile. At the same time, the pressing mechanism cleans the surface of the water inlet pipe through the retaining ring to avoid blockage of the water inlet pipe and reduce the impact of water accumulation on the soil cleaning of the pipe pile core.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-9 The present invention provides the following technical solution:

[0037] A hydraulic soil compaction device for cleaning the core of pipe piles includes a pipe pile 1, a reinforcing bar 2, a clamping mechanism 3, a pressing mechanism 4, a water collection mechanism 5, and a straightening mechanism 6.

[0038] The bottom of the pipe pile 1 is inserted into the foundation pit. The top of the pipe pile 1 is provided with a reinforcing bar 2. One end of the reinforcing bar 2 is provided with a clamping mechanism 3. One side of the clamping mechanism 3 is provided with a pressing mechanism 4. The top of the pressing mechanism 4 is provided with a water collection mechanism 5. The bottom of the pressing mechanism 4 is provided with a regularizing mechanism 6.

[0039] The clamping mechanism 3 includes a movable clamping plate 301, one side of which is connected to the pipe pile 1. A screw rod 302 is provided on one side of the movable clamping plate 301, a connecting block 303 is provided at one end of the screw rod 302, and a movable block 304 is provided at the end of the screw rod 302 away from the connecting block 303. A stop spring 305 is provided on one side of the movable block 304, and a baffle 306 is provided at the end of the stop spring 305 away from the movable block 304. The movable clamping plate 301 fits against and supports the top of the pipe pile 1. By rotating the screw rod 302, the position of the connecting block 303 on the screw rod is adjusted. The connecting block 303 moves horizontally along the screw rod 302 to clamp the reinforcing bar 2 at the top of the pipe pile 1. The connecting block 303 can clamp reinforcing bars 2 of various sizes, improving the applicability of the device. The reinforcing bar 2 is used to quickly fix the position of the device, saving the operator's operation time and improving the working efficiency of the device.

[0040] One side of the movable clamping plate 301 is connected to the connecting clamping block 303 through a groove. One side of the baffle 306 is engaged with the movable clamping plate 301, and the bottom of the baffle 306 is connected to the inner wall of the pipe pile 1. While rotating the lead screw 302, the lead screw 302 drives the movable clamping block 304 to move synchronously. The movable clamping block 304 compresses the resisting spring 305. The resisting spring 305, under pressure, pushes the baffle 306 to move horizontally, engaging one side of the baffle 306 with the inner wall of the pipe pile 1, improving the fit between the device and the pipe pile 1, and enhancing the stability of the device.

[0041] The pressing mechanism 4 includes a support plate 401, one side of which is hinged to a movable clamping plate 301. Several movable clamping plates 301 are provided, and they are distributed equidistantly in a ring around the inner wall of the pipe pile 1. A hydraulic cylinder 402 is provided at the bottom of the support plate 401, and a bulldozer plate 403 is provided at the bottom end of the hydraulic cylinder 402. A clamping rod 404 is hinged inside the bulldozer plate 403, and a retaining ring 405 is provided at the bottom of the bulldozer plate 403. The bulldozer plate 403 is tapered. The movable clamping plate 301 is deflected along one side of the support plate 401 to adjust the position of the support plate 401 at the top of the pipe pile 1. The relative position of the bulldozing plate 403 at the bottom of the support plate 401 and the inner wall of the pipe pile 1 is adjusted to improve the precision of the device. The hydraulic cylinder 402 is activated to drive the bulldozing plate 403 at the bottom to press down. The soil at the bottom of the inner core of the pipe pile 1 is compacted and cleaned by the conical bulldozing plate 403, which reduces the labor consumption of manual operation and lowers the construction cost.

[0042] The water collection mechanism 5 includes a water storage tank 501, which is connected to the upper surface of the support plate 401. A water guide pipe 502 is installed on the top of the water storage tank 501, one end of which is connected to a hydraulic cylinder 402. A water inlet pipe 503 is installed at the bottom of the water guide pipe 502. The horizontal height of the water storage tank 501 is higher than the horizontal height of the water inlet pipe 503. The water guide pipe 502 is U-shaped. The water inlet pipe 502 contacts the water at the bottom of the core of the pipe pile 1. After water is filled into the water guide pipe 502, the U-shaped structure of the water guide pipe 502 forms a siphon structure, filtering the water at the bottom of the core of the pipe pile 1 through the water inlet pipe 503 and then drawing it into the water storage tank 501 through the water guide pipe 502. This reduces the impact of accumulated water on the compaction of the soil inside the core of the pipe pile 1 and improves the processing quality of the device.

[0043] The bottom of the bulldozer blade 403 has a through hole, through which the water inlet pipe 503 is connected. The water inlet pipe 503 is engaged with the clamping rod 404, and the outer wall of the water inlet pipe 503 is connected with the retaining ring 405. The extension of the hydraulic cylinder 402 causes the bulldozer blade 403 to press down. While the bulldozer blade 403 is compressing the soil, it also causes the clamping rod 404 to deflect, releasing the engagement between the clamping rod 404 and the water inlet pipe 503. The water inlet pipe 503 is then lowered through the through hole at the bottom of the bulldozer blade 403 to the bottom of the compacted pit after being compacted by the conical bulldozer blade 403. The water inlet pipe 503 filters the silt and sand in the accumulated water. Subsequently, while the bulldozer blade 403 is pressed down a second time, the retaining ring 405 scrapes and cleans the outer wall of the water inlet pipe 503 to prevent clogging.

[0044] The straightening mechanism 6 includes a fixed sleeve 601, the inner wall of which is connected to a hydraulic cylinder 402. The outer wall of the fixed sleeve 601 has a sliding groove 602. The outer wall of the fixed sleeve 601 is provided with a movable sleeve 603. The outer wall of the movable sleeve 603 is provided with a push rod 604. The top of the push rod 604 is provided with a movable spring 605. The bottom end of the push rod 604 is hinged to a rotating rod 607. The end of the rotating rod 607 away from the push rod 604 is provided with a support rod 609. The support rod 609 is arc-shaped. A top rod 608 is provided on one side of the support rod 609. The end of the top rod 608 away from the support rod 609 is hinged to the top of the bulldozer plate 403. The side of the support rod 609 away from the top rod 608 is provided with a rubber sleeve 6010. The bottom of the rubber sleeve 6010 is connected to the bulldozer plate 403. As the hydraulic cylinder 402 extends, the top of the bulldozer plate 403 drives the push rod 604 to extend synchronously. The bottom end of the push rod 604 drives the rotating rod 607 to deflect, and the bottom end of the rotating rod 607 drives the top rod 608 to deflect. As the top rod 608 deflects along the top of the bulldozer plate 403, it pushes the support rod 609 outward. The support rod 609 stretches the rubber sleeve 6010 outward, bringing the rubber sleeve 6010 into contact with the inner wall of the pipe pile 1. After the support rod 609 touches the inner wall of the pipe pile 1, the top end of the push rod 604 squeezes the movable spring 605 to buffer the downward pressure of the hydraulic cylinder 402. After the rubber sleeve 6010 is in contact with the inner wall of the pipe pile 1, the bulldozer plate 403 continues to press down to pressurize the bottom of the pipe pile 1, quickly squeezing the water into the water storage tank 501. At the same time, the rubber sleeve 6010 cleans the inner wall of the pipe pile 1, reducing the impact of mud and sand adhesion on subsequent construction.

[0045] The top of the movable sleeve 603 is provided with a positioning spring 606, the top of which is connected to the support plate 401. The slide groove 602 is V-shaped and has several sections. The slide grooves 602 are distributed in a ring around the outer wall of the fixed sleeve 601. The inner wall of the movable sleeve 603 is provided with a protrusion, which engages with the slide groove 602. Several push rods 604 are provided and are evenly distributed in a ring around the outer wall of the movable sleeve 603. While the hydraulic cylinder 402 extends and retracts, the push rod 604 drives the movable sleeve 603 to slide along the outer wall of the fixed sleeve 601. When the hydraulic cylinder 402 extends, the push rod 604 drives the movable sleeve 603 to move downward. The protrusion on the inner wall of the movable sleeve 603 moves to the bottom of the V-shaped groove 602. Then the hydraulic cylinder 402 retracts, and the movable sleeve 603 squeezes the positioning spring 606. The movable sleeve 603 slides along the groove 602 through the protrusion on the inner wall. At the same time, the movable sleeve 603 deflects. The movable sleeve 603 drives the push rod 604 and the support rod 609 to deflect synchronously, so as to avoid the gap of the circumferential arrangement of the support rod 609 from causing omissions in the cleaning of the inner wall of the pipe pile 1, and improve the cleaning effect of this device on the inside of the pipe pile 1.

[0046] Working principle of the invention:

[0047] First, the position of the device is quickly fixed by the clamping mechanism 3. The position of the connecting block 303 on the screw is adjusted by rotating the screw 302. The connecting block 303 moves horizontally along the screw 302 to clamp the reinforcing bar 2 at the top of the pipe pile 1. The reinforcing bar 2 is clamped by the connecting block 303, and the position of the device is quickly fixed by the reinforcing bar 2. While rotating the screw 302, the screw 302 drives the movable block 304 to move synchronously. The movable block 304 squeezes the resisting spring 305. While the resisting spring 305 is compressed, it pushes the baffle 306 to move horizontally, and clamps one side of the baffle 306 with the inner wall of the pipe pile 1 to ensure the stability of the pressing mechanism 4 on one side of the clamping mechanism 3. While rotating the screw 302, the movable block 301 is deflected along one side of the support plate 401 to adjust the position of the support plate 401 at the top of the pipe pile 1 and adjust the relative position of the bulldozer plate 403 at the bottom of the support plate 401 and the inner wall of the pipe pile 1.

[0048] Then, the pressing mechanism 4 is activated to compact the soil at the bottom of the inner core of the pipe pile 1. The hydraulic cylinder 402 is activated to drive the bulldozer plate 403 set at the bottom to press down. The conical bulldozer plate 403 compacts and cleans the soil at the bottom of the inner core of the pipe pile 1. While the bulldozer plate 403 is pressing down, the conical structure of the bulldozer plate 403 presses the soil at the bottom of the inner core of the pipe pile 1 into a conical pit. While the hydraulic cylinder 402 extends and drives the bulldozer plate 403 to press down, the bulldozer plate 403 squeezes the soil layer and drives the clamping rod 404 to deflect, releasing the clamping rod 404 from the water inlet pipe 503. The water inlet pipe 503 is lowered through the through hole at the bottom of the bulldozer plate 403. The water inlet pipe 503 is lowered to the bottom of the conical pit. Then the hydraulic cylinder 402 is retracted to prepare for secondary compaction.

[0049] When the hydraulic cylinder 402 extends again, the bulldozer plate 403 descends. The top of the bulldozer plate 403 drives the push rod 604 to extend synchronously. The bottom end of the push rod 604 drives the rotating rod 607 to deflect. The bottom end of the rotating rod 607 drives the top rod 608 to deflect. As the top rod 608 deflects along with the top of the bulldozer plate 403, it pushes the support rod 609 outward. The support rod 609 stretches the rubber sleeve 6010 outward, bringing the rubber sleeve 6010 into contact with the inner wall of the pipe pile 1. The support rod 609 touches the inside of the pipe pile 1. After the wall is closed, the top of the push rod 604 presses the movable spring 605 to buffer the downward pressure of the hydraulic cylinder 402. After the rubber sleeve 6010 is in contact with the inner wall of the pipe pile 1, the bulldozer plate 403 continues to press down to pressurize the bottom of the pipe pile 1, squeezing the water into the water storage tank 501. At the same time, the rubber sleeve 6010 cleans the inner wall of the pipe pile 1 and scrapes off the mud adhering to the inner wall of the pipe pile 1. Meanwhile, the retaining ring 405 set at the bottom of the bulldozer plate 403 scrapes off the mud and sand on the outer wall of the water inlet pipe 503.

[0050] The water in the inlet pipe 503 comes into contact with the water at the bottom of the inner core of the pipe pile 1. After water is filled into the water guide pipe 502, the U-shaped structure of the water guide pipe 502 forms a siphon structure, which filters the water at the bottom of the inner core of the pipe pile 1 through the inlet pipe 503 and then draws it into the water storage tank 501 through the water guide pipe 502.

[0051] As the hydraulic cylinder 402 extends and retracts, the push rod 604 drives the movable sleeve 603 to slide along the outer wall of the fixed sleeve 601. When the hydraulic cylinder 402 extends, the push rod 604 drives the movable sleeve 603 to move downward. The protrusion on the inner wall of the movable sleeve 603 moves to the bottom of the V-shaped groove 602. Then the hydraulic cylinder 402 retracts, and the movable sleeve 603 squeezes the positioning spring 606. The movable sleeve 603 slides along the groove 602 through the protrusion on its inner wall. At the same time, the movable sleeve 603 deflects, which drives the push rod 604 and the support rod 609 to deflect synchronously, so that the support rod 609 can evenly scrape and clean the inner wall of the pipe pile 1.
