Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, in particular to a concrete pouring device for cast-in-place pile construction. Background Art

[0002] With the rapid development of my country's high-speed rail, there are more and more tunnels. In the construction of tunnel excavation, it is easy to encounter under-consolidated soil layers such as loose piled soil and backfill soil, which causes the overall or local settlement of the tunnel during the tunnel excavation process. In the process of tunnel excavation and support, there are problems such as insufficient support strength, large deformation of the tunnel surrounding rock, and damage to the support structure, which poses a great threat to the safety of the tunnel support structure and the stability of operation. In order to solve the settlement problem of this special bottom layer under the tunnel, in-hole construction cast-in-place pile foundation reinforcement is often used.

[0003] During the construction of existing bored piles, a hole is usually drilled by a drilling machine (or manually), and then a prefabricated steel cage is hoisted into the hole, and then concrete is poured using a pipe. Due to the long and deep pile length of the bored pile, the traditional vibrator cannot reach the bottom of the bored pile. After the concrete is transported from the pipe to the bottom of the bored pile, the concrete can only be compacted by relying on the slump of the concrete itself. This method is prone to cause bubbles to appear during the pouring process, which will seriously reduce the bearing capacity of the pile. In addition, relying entirely on the slump of the concrete to ensure the density of the concrete will lead to a slow progress in concrete pouring.

[0004] Based on this, the present invention designs a concrete pouring device for cast-in-place pile construction to solve the above problems. Summary of the Invention

[0031] The sliding sleeve 4 is rotatably connected to a second rotating ring 12, and the second rotating ring 12 is fixedly connected to a telescopic rod 13, and the bottom end of the telescopic rod 13 is fixedly connected to a mounting ring 14; a tamping plate 15 is fixedly connected to the mounting ring 14, and the bottom surface of the tamping plate 15 is in contact with the top surface of the stirring block 7; the stirring block 7 and the tamping plate 15 are respectively provided with a first inclined surface 16 and a second inclined surface 17; the first inclined surface 16 and the second inclined surface 17 can be in contact with each other; a first slide groove 18 is provided on the sliding sleeve 4, and the first slide groove 18 consists of a transverse groove 181 and an inclined groove 182, and the transverse groove 181 is connected to the inclined groove 182; a second guide slider 19 is slidably connected in the first slide groove 18, and the second guide slider 19 is fixedly connected to the mounting ring 14; a first pressure sensor 25 and a second pressure sensor 29 are provided in the mounting frame 9;

[0032] A drive assembly and a trigger assembly are provided in the mounting frame 9; when the trigger assembly squeezes the first pressure sensor 25, the drive assembly drives the sleeve 4 to rotate clockwise, and when the trigger assembly squeezes the second pressure sensor 29, the drive assembly drives the sleeve 4 to rotate counterclockwise.

[0033] When the above solution is put into practical use, Figure 1-2 As shown; after the bored pile is drilled, the steel cage is vertically hoisted into the bored pile and fixed; then the grouting pipe 1 is vertically hoisted into the bored pile, and the grouting pipe 1 is located inside the steel cage; when the mixing block 7 contacts the bottom of the bored pile, the grouting pipe 1 is lifted upward by 30-50 cm; then the prepared concrete is poured into the grouting pipe 1, and after the concrete falls to the bottom of the grouting pipe 1, it overflows from the grouting hole 2 and falls into the bored pile; as shown Figure 2 As shown, while the concrete is being poured, the drive assembly is activated to rotate the first rotating ring 3 counterclockwise. In the initial state, the trigger assembly is in contact with the second pressure sensor 29. The first rotating ring 3 drives the sliding sleeve 4 to rotate synchronously, and the sliding sleeve 4 drives the stirring block 7 to rotate synchronously. The stirring block 7 stirs the concrete while rotating. The concrete surface is required to be 30-50 cm above the stirring block 7. While the concrete is being poured, the pouring pipe 1 is slowly lifted upward. The stirring block 7 rotates and drives the wave chute 5 to rotate synchronously. Under the action of the first guide slider 6 and the wave chute 5, the stirring block 7 circulates in the vertical direction while rotating. When the stirring block 7 rotates, it can stir the concrete and drive out the bubbles in the concrete through stirring; when the stirring block 7 moves upward, it can drive the concrete above the stirring block 7 to vibrate, so that the bubbles in the concrete can be discharged better; since the bottom surface of the stirring block 7 is set to be flat; when the stirring block 7 moves downward, the stirring block 7 can beat the concrete below the stirring block 7 after the bubbles are driven out, and can compact the concrete below the stirring block 7; when the stirring block 7 moves slowly upward following the pouring pipe 1, the stirring block 7 will stir and compact the concrete newly poured into the cast-in-place pile in turn;

[0034] It should be noted that in this design, the lifting speed of the pouring pipe 1 needs to be slightly greater than the pouring speed of the concrete; Figure 2 and Figure 4 As shown, the mixing block 7 rotates counterclockwise when mixing concrete; at this time, the second guide slider 19 is located at the leftmost end of the transverse groove 181, and the sliding sleeve 4 will drive the first slide 18 to rotate counterclockwise synchronously while rotating, and the first slide 18 will drive the second guide slider 19 to rotate counterclockwise synchronously, and the second guide slider 19 will drive the mounting ring 14 to rotate synchronously (as shown in FIG. Figure 6As shown); the mounting ring 14 will drive the tamping plate 15 to rotate synchronously. In this state, the tamping plate 15 is in contact with the top surface of the stirring block 7; the tamping plate 15 and the stirring block 7 work together to stir; when the stirring block 7 rotates for a period of time, the trigger component will squeeze the first pressure sensor 25, and then the driving component will drive the sleeve 4 to rotate clockwise; the sleeve 4 will drive the stirring block 7 to rotate clockwise, at this time the stirring block 7 is lifted to a position where its bottom surface is close to the concrete surface, and then the pouring pipe 1 will stop lifting until the trigger component triggers the second pressure sensor 29 again, but the concrete can continue to be poured; when the sleeve 4 rotates clockwise, under the action of inertia, the second guide slider 19 will move counterclockwise relative to the sleeve 4, and the second guide slider 19 will slide to the right in the transverse groove 181 (as shown in FIG. Figure 4 、 Figure 5 As shown), the second guide slider 19 slides from the transverse groove 181 into the inclined groove 182, and then moves downward along the inclined groove 182; when the second guide slider 19 slides in the transverse groove 181, it drives the mounting ring 14 to move synchronously, and the mounting ring 14 drives the second rotating ring 12 to rotate counterclockwise relative to the sliding sleeve 4 through the telescopic rod 13; when the second guide slider 19 moves downward in the inclined groove, the mounting ring 14 drives the telescopic rod 13 to extend; when the second guide slider 19 moves to the bottom end of the inclined groove 182, the tamping plate moves to the bottom end as shown. Figure 9 In the position shown, the first inclined surface 16 and the second inclined surface 17 are tightly fitted with each other, and the tamping plate and the stirring block 7 are combined into a complete disc; at this time, since the second guide slider 19 is located at the bottom end of the chute 182 and can no longer move, the sliding sleeve 4 will drive the mounting ring 14 to rotate synchronously clockwise, and the sliding sleeve 4 will also circulate in the vertical direction under the cooperation of the wave chute 5 and the first guide slider 6. At this time, the disc formed by the tamping plate and the stirring block 7 will slap the concrete below it, which can better compact the poured concrete as a whole; when the tamping plate and the stirring block 7 have been compacted together for a period of time, the trigger assembly will squeeze the second pressure sensor 29 again, and the drive assembly will drive the sliding sleeve 4 to rotate counterclockwise again. At this time, the pouring pipe 1 starts to rise again, and the tamping plate 15 will return to the position of fitting with the top surface of the stirring block 7 again, and then the tamping plate 15 and the stirring block 7 will stir the concrete again;

[0035] The present invention is provided with the stirring block 7, and the stirring block 7 can stir the concrete while the concrete is being poured, and can drive out the bubbles in the concrete through the stirring effect, so that no honeycomb will appear in the concrete after the bored pile is formed, thereby ensuring the bearing capacity of the bored pile; by the coordinated use of the wave chute 5 and the first guide slider 6, the stirring block 7 can be made to circulate in the vertical direction while rotating, and when the stirring block 7 moves upward, it can drive the concrete above the stirring block 7 to vibrate, so that the bubbles in the concrete can be better discharged; because the bottom surface of the stirring block 7 is set to be flat; when the stirring block 7 moves downward, the stirring block 7 can slap and stir the concrete below the stirring block 7 after the bubbles are driven out, and can play a tamping effect on the concrete below the stirring block 7; it can accelerate the density of the concrete, and when the bored pile is filled with concrete, the concrete is in a dense state, which can greatly accelerate the progress of concrete pouring;

[0036] The present invention is provided with a tamping plate 15, a first pressure sensor 25 and a trigger assembly. Every time the concrete is poured to a certain height, the trigger assembly will cyclically trigger the first pressure sensor 25. When the trigger assembly squeezes the first pressure sensor 25, the sliding sleeve 4 rotates clockwise, so that the tamping plate 15 and the stirring block 7 can form a complete disc. Then, with the cooperation of the wave chute 5 and the first guide slider 6, the disc can cyclically move in the vertical direction. The disc can slap the concrete below it, which can better compact the entire poured concrete. Without affecting the pouring speed, the concrete can be made denser better and faster.

[0037] As a further solution of the present invention, the drive assembly includes a first bevel gear 8 and a motor 11; the first bevel gear 8 is fixedly connected to the first rotating ring 3, and the first bevel gear 8 is engaged with a second bevel gear 10; the motor 11 is fixedly connected to the mounting frame 9, and the output shaft of the motor 11 is fixedly connected to the rotating shaft of the second bevel gear 10.

[0038] When the above-mentioned drive components are actually working, Figure 2 As shown, start the motor 11, the motor 11 will drive the second bevel gear 10 to rotate, the second bevel gear 10 will drive the first bevel gear 8 to rotate, and the first bevel gear 8 will drive the first rotating ring 3 to rotate; the mounting frame 9 will protect the motor 11, the first bevel gear 8 and the second bevel gear 10, so that the concrete will not interfere with the normal operation of the motor 11, the first bevel gear 8 and the second bevel gear 10.

[0039] As a further solution of the present invention, the trigger assembly includes a worm gear 20; the worm gear 20 is fixedly connected to the rotating shaft of the second bevel gear 10, the worm gear 20 is engaged with a worm 21, the worm 21 is rotatably connected to the mounting frame 9, and a rotating sleeve 22 is fixedly connected to the rotating shaft of the worm 21, the rotating sleeve 22 is threadedly connected to a threaded rod 23, and a guide rod 24 is slidably connected to the threaded rod 23, and the guide rod 24 is fixedly connected to the mounting frame 9; the first pressure sensor 25 is fixedly connected to the guide rod 24, and the second pressure sensor 29 is fixedly connected to the rotating sleeve 22; the first pressure sensor 25 and the second pressure sensor 29 are electrically connected to the motor 11.

[0040] When the above trigger components are actually working, Figure 7 、 Figure 8 and Figure 10 As shown, when the motor 11 drives the second bevel gear 10 to rotate, the second bevel gear 10 will drive the worm gear 20 to rotate, the worm gear 20 will drive the worm 21 to rotate, and the worm 21 will drive the rotating sleeve 22 to rotate, and the rotating sleeve 22 will drive the threaded rod 23 to slide upward on the guide rod 24 through the thread. When the threaded rod 23 moves upward to contact the first pressure sensor 25, the threaded rod 23 moves upward again to squeeze the first pressure sensor 25; the first pressure sensor 25 will transmit a signal to the motor 11, and the motor 11 starts to rotate in the opposite direction. The motor 11 will drive the second bevel gear 10 and the worm gear 20 to rotate in the opposite direction, the worm gear 20 will drive the worm 21 to rotate in the opposite direction, and the worm 21 will drive the rotating sleeve 22 to rotate in the opposite direction, and then the rotating sleeve 22 will drive the threaded rod 23 to move downward. When the threaded rod 23 moves downward to the initial position, the threaded rod 23 will squeeze the second pressure sensor 29, and the second pressure sensor 29 will transmit a signal to the motor 11, and the motor 11 changes the rotation direction again, and the cycle continues.

[0041] As a further solution of the present invention, the bottom of the mounting frame 9 is located below the first slide groove 18, and the inner wall of the mounting frame 9 is in contact with the outer wall of the mounting ring 14; when working, the mounting frame 9 can seal the mounting ring 14, thereby ensuring that concrete does not enter the interior of the mounting frame 9 and does not affect the normal operation of the mounting ring 14, thereby greatly improving the service life of the device.

[0042] As a further solution of the present invention, a spring 26 is mounted on the telescopic rod 13, and the top and bottom ends of the spring 26 are fixedly connected to the second rotating ring 12 and the mounting ring 14 respectively; during operation, the setting of the spring 26 can enable the mounting ring 14 and the tamping plate 15 to cooperate with the stirring block 7 more quickly.

[0043] As a further solution of the present invention, a material guide platform 27 is fixedly connected to the top of the mounting frame 9. The material guide platform 27 is located outside the grouting pipe 1 and fits with the grouting pipe 1. During operation, the setting of the material guide platform 27 can make the concrete fall into the cast-in-place pile better.

[0044] As a further solution of the present invention, a material guiding slope 28 is provided on the installation frame 9 ; during operation, the material guiding slope 28 can prevent concrete from accumulating on the installation frame 9 .

[0045] Working principle: Figure 1-2 As shown; after the bored pile is drilled, the steel cage is vertically hoisted into the bored pile and fixed; then the grouting pipe 1 is vertically hoisted into the bored pile, and the grouting pipe 1 is located inside the steel cage; when the mixing block 7 contacts the bottom of the bored pile, the grouting pipe 1 is lifted upward by 30-50 cm; then the prepared concrete is poured into the grouting pipe 1, and after the concrete falls to the bottom of the grouting pipe 1, it overflows from the grouting hole 2 and falls into the bored pile; as shown Figure 2 As shown, while the concrete is being poured, the drive assembly is activated to rotate the first rotating ring 3 counterclockwise. In the initial state, the trigger assembly is in contact with the second pressure sensor 29. The first rotating ring 3 drives the sliding sleeve 4 to rotate synchronously, and the sliding sleeve 4 drives the stirring block 7 to rotate synchronously. The stirring block 7 stirs the concrete while rotating. The concrete surface is required to be 30-50 cm above the stirring block 7. While the concrete is being poured, the pouring pipe 1 is slowly lifted upward. The stirring block 7 rotates and drives the wave chute 5 to rotate synchronously. Under the action of the first guide slider 6 and the wave chute 5, the stirring block 7 circulates in the vertical direction while rotating. When the stirring block 7 rotates, it can stir the concrete and drive out the bubbles in the concrete through stirring; when the stirring block 7 moves upward, it can drive the concrete above the stirring block 7 to vibrate, so that the bubbles in the concrete can be discharged better; since the bottom surface of the stirring block 7 is set to be flat; when the stirring block 7 moves downward, the stirring block 7 can beat the concrete below the stirring block 7 after the bubbles are driven out, and can compact the concrete below the stirring block 7; when the stirring block 7 moves slowly upward following the pouring pipe 1, the stirring block 7 will stir and compact the concrete newly poured into the cast-in-place pile in turn;

[0046] It should be noted that in this design, the lifting speed of the pouring pipe 1 needs to be slightly greater than the pouring speed of the concrete; Figure 2 and Figure 4As shown, the mixing block 7 rotates counterclockwise when mixing concrete; at this time, the second guide slider 19 is located at the leftmost end of the transverse groove 181, and the sliding sleeve 4 will drive the first slide 18 to rotate counterclockwise synchronously while rotating, and the first slide 18 will drive the second guide slider 19 to rotate counterclockwise synchronously, and the second guide slider 19 will drive the mounting ring 14 to rotate synchronously (as shown in FIG. Figure 6 The mounting ring 14 drives the tamping plate 15 to rotate synchronously. In this state, the tamping plate 15 is in contact with the top surface of the stirring block 7. The tamping plate 15 and the stirring block 7 work together to stir the mixture. After the stirring block 7 rotates for a period of time, the trigger assembly squeezes the first pressure sensor 25, and then the drive assembly drives the sleeve 4 to rotate clockwise.

[0047] The sliding sleeve 4 will drive the stirring block 7 to rotate clockwise. At this time, the stirring block 7 is lifted to a position where its bottom surface is close to the concrete surface. Thereafter, the pouring pipe 1 will stop lifting until the trigger assembly triggers the second pressure sensor 29 again, but concrete can continue to be poured. When the sliding sleeve 4 rotates clockwise, under the action of inertia, the second guide slider 19 will move counterclockwise relative to the sliding sleeve 4, and the second guide slider 19 will slide to the right in the transverse groove 181 (as shown in FIG. Figure 4 、 Figure 5 As shown), the second guide slider 19 slides from the transverse groove 181 into the inclined groove 182, and then moves downward along the inclined groove 182; when the second guide slider 19 slides in the transverse groove 181, it drives the mounting ring 14 to move synchronously, and the mounting ring 14 drives the second rotating ring 12 to rotate counterclockwise relative to the sliding sleeve 4 through the telescopic rod 13; when the second guide slider 19 moves downward in the inclined groove, the mounting ring 14 drives the telescopic rod 13 to extend; when the second guide slider 19 moves to the bottom end of the inclined groove 182, the tamping plate moves to the bottom end as shown. Figure 9 In the position shown, the first inclined surface 16 and the second inclined surface 17 are tightly fitted with each other, and the tamping plate and the stirring block 7 are combined into a complete disc; at this time, since the second guide slider 19 is located at the bottom end of the inclined groove 182 and can no longer move, the sleeve 4 will drive the mounting ring 14 to rotate synchronously clockwise, and the sleeve 4 will also circulate in the vertical direction with the cooperation of the wave chute 5 and the first guide slider 6. At this time, the disc formed by the tamping plate and the stirring block 7 will slap the concrete below it, which can better compact the poured concrete as a whole; when the tamping plate and the stirring block 7 have been compacted together for a period of time, the trigger assembly will squeeze the second pressure sensor 29 again, and the drive assembly will drive the sleeve 4 to rotate counterclockwise again. At this time, the pouring pipe 1 starts to rise again, and the tamping plate 15 will return to the position in contact with the top surface of the stirring block 7, and then the tamping plate 15 and the stirring block 7 will stir the concrete again.
