Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a concrete pouring device and method for the wall panels of a large underground circular structure. Background Technology

[0002] In engineering projects such as chemical, petroleum, pharmaceutical, and municipal engineering, the construction of numerous circular structures, such as underground pools and pile foundations, is often involved. The wall panels are typically constructed using cast-in-place concrete. Traditionally, concrete pump trucks are commonly used for concrete delivery and pouring.

[0003] In practical applications, firstly, due to the limited underground working space, concrete pump trucks need to be placed close to the edge of the foundation pit. During the pouring process, 2-4 concrete workers are required to operate the pump, and at least 2 workers are required to perform vibration operations. At the same time, 2-4 carpenters are also required to monitor the formwork in real time, resulting in a large personnel investment. Secondly, due to the complex working environment, underground areas are prone to safety accidents such as collapses, formwork bulging, and falling objects from heights, posing a great safety risk to on-site construction personnel. Thirdly, the traditional pump truck pouring method makes it difficult to achieve precise control of the concrete pouring height, which can easily lead to uneven material distribution, under-vibration, or over-vibration, affecting the quality of concrete molding.

[0004] Furthermore, due to the lack of effective remote monitoring methods, it is difficult to grasp the flow state of concrete inside the formwork and the deformation of the formwork in real time during the construction process. It often relies on manual experience to make judgments, which increases the difficulty of construction management and the uncertainty of quality control.

[0005] To address these issues, a device and method for pouring concrete for the wall panels of large underground circular structures are provided. Summary of the Invention

[0047] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0048] Example 1

[0049] To address the problems of poor construction safety, high labor intensity, low automation, and high difficulty in quality control associated with existing pouring equipment, please refer to... Figures 1-2 The present invention provides a concrete pouring device for the wall panels of a large underground circular structure, comprising:

[0050] Support component 1 is used to be installed circumferentially along the edge of the foundation pit of a circular structure to form a pouring area;

[0051] The material conveying assembly is used to transport concrete to the center position within the foundation pit;

[0052] The feeding assembly 4 has its inlet end located at the center of the pit and its outlet end rotatably set along the edge of the pit. It is used to receive the concrete from the conveying assembly and rotate and transport the concrete to various positions in the pouring area.

[0053] Vibration assembly 5 is used to vibrate the concrete delivered to the pouring area;

[0054] Monitoring component 6 is used to remotely monitor the operation of each component.

[0055] like Figure 7 As shown, the support assembly 1 includes a template 101 surrounding the perimeter of the foundation pit, a scaffolding pipe 102 erected on the outside of the template 101, and a vibrator guide plate 103 fixed on the upper edge of the template 101. The vibrator guide plate 103 is inclined at a 60-70° angle to guide the vibrator assembly 5 to be inserted into the concrete for vibration operation, ensuring the compactness of the concrete.

[0056] like Figures 7-12As shown, the feeding assembly 4 includes an inclined feeding trough 401, and a second support frame 402 and a third support frame 403 located at both ends of the feeding trough 401. The feeding trough 401 is an open chute. The bottom of the second support frame 402 is provided with a rotating wheel 404, and the bottom of the third support frame 403 is provided with a track wheel 405 and a driving component for driving the track wheel 405 to move. A fixed plate 406 matching the rotating wheel 404 is provided at the center of the pit. The fixed plate 406 is circular and has fixed teeth at the bottom. The fixed plate 406 is pressed on the center of the pit bottom to support the rotating wheel 404, so as to realize the stable rotation of the feeding assembly 4 around the center of the pit. A first annular track 407 matching the track wheel 405 is provided at the periphery edge of the pit. The second support frame 402 includes a second guard plate 402a fixedly disposed at the bottom of the feeding trough 401, and a center leg 402b fixedly disposed at the bottom of the second guard plate 402a; the third support frame 403 includes a third guard plate 403a fixedly disposed at the bottom of the feeding trough 401, with second crossbars 403b fixedly disposed on both sides of the third guard plate 403a, and second wheel posts 403c fixedly disposed at the ends of the second crossbars 403b, with track wheels 405 disposed at the bottom of the second wheel posts 403c, and a second reinforcing rod 403d disposed between the bottom ends of the two second wheel posts 403c to enhance structural stability and achieve smooth movement along the first annular track 407.

[0057] The first circular track 407 is composed of multiple arc-shaped angle steel tracks 407a, which are sequentially spliced ​​together. Track wheels 405 are installed on the angle steel tracks 407a. Insert tubes 407b and bearing tubes 407c are welded to both ends of the angle steel tracks 407a, respectively. Adjacent angle steel tracks 407a are connected by inserting the insert tubes 407b and bearing tubes 407c, and then fastened with bolts. The first circular track 407 adopts a multi-segment structure, which can be quickly assembled and fixed with bolts during on-site construction, adapting to foundation pits of circular structures of different diameters.

[0058] During the concrete pouring process, the concrete enters the feeding trough 401 through the feeding assembly 3 and flows towards the support assembly 1 by gravity through its inclined structure. One end of the feeding assembly 4 cooperates with the ground fixed plate 406 through the rotating wheel 404 at the bottom of the central leg 402b to achieve rotational support around the center of the foundation pit; the other end slides along the first annular track 407 through the track wheel 405 on the second wheel column 403c. The driving component drives the track wheel 405 to rotate, so that the entire feeding assembly 4 rotates at a uniform speed along the first annular track 407, thereby evenly distributing the concrete to the inside of the support assembly 1 to achieve continuous and uniform circumferential distribution.

[0059] The feeding assembly 4 also includes a limiting unit for controlling the concrete pouring height. The limiting unit includes a limit switch 408 located at the end of the feeding trough 401 and a limiting plate 409 located on the limit switch 408. The limit switch 408 is electrically connected to the drive component of the track wheel 405 via a data cable and is used to control the movement and stopping of the track wheel 405 when the concrete is stacked to a set height.

[0060] When the concrete piles up to the preset height, it will contact and push the limit plate 409, which will trigger the limit switch 408 to send an electrical signal. The external control component controls the drive of the track wheel 405 to move and stop, thereby realizing automatic control of the concrete pouring height.

[0061] like Figures 5-6 As shown, the feeding assembly includes an inclined feeding assembly 2 and a vertically arranged unloading assembly 3. The feeding assembly 2 includes an inclined feeding trough 201 and a first support frame 202 fixed at both ends of the feeding trough 201. The feeding trough 201 is an open chute. The bottom of the first support frame 202 is provided with a roller 203. The first support frame 202 includes a first guard plate 202a fixed at the bottom of the feeding trough 201. Both sides of the first guard plate 202a are fixed with first crossbars 202b. The ends of the first crossbars 202b are fixed with first wheel columns 202c. The roller 203 is located at the bottom of the first wheel columns 202c. A first reinforcing rod 202d is provided between the bottom ends of the two first wheel columns 202c to enhance the structural stability of the feeding assembly 2 and achieve stable sliding along the wheel groove 805.

[0062] During the concrete pouring operation, the concrete mixer truck delivers the concrete to the high-end inlet of the feeding chute 201. The concrete slides down the inclined feeding chute 201 by gravity and eventually flows into the inlet of the feeding assembly 3. The feeding assembly 2 slides in the wheel groove 805 through the roller 203 and can move along the crossbeam frame 8. The first guard plate 202a and the first reinforcing rod 202d ensure the structural stability and safety of the feeding assembly 2 during movement and operation.

[0063] The feeding assembly 3 includes a feeding hopper 301 and a feeding pipe 302 with adjustable length located at the discharge port of the feeding hopper 301. The feeding pipe 302 is composed of multiple pipe sections spliced ​​together in sequence. Each pipe section and the uppermost pipe section are detachably connected to the feeding hopper 301 through a flange structure.

[0064] During the concrete pouring process, the feeding assembly 2 delivers the concrete to the discharge hopper 301, and then the concrete enters the discharge pipe 302 below through the discharge hopper 301. Since the discharge pipe 302 is composed of multiple pipe sections connected by flanges, the total length of the discharge pipe 302 can be flexibly adjusted according to the height of the support assembly 1 or the depth of the circular foundation pit during actual construction, so as to ensure that the concrete can be stably and continuously delivered to the feeding assembly 4.

[0065] like Figures 3-4 As shown, the device also includes a crossbeam frame 8 spanning across the pit for installing the material conveying assembly; the crossbeam frame 8 includes a support beam 801 and a rope ladder 803 hanging on the support beam 801 and extending to the bottom of the pit, the material feeding assembly 2 is slidably mounted on the top of the support beam 801, the material unloading assembly 3 is fixedly mounted on the bottom of the support beam 801, the support beam 801 is provided with a walkway 804 and wheel grooves 805 that match the rollers 203, and railings 802 are provided on both sides of the walkway 804 and the perimeter of the pit. The support beam 801 is made of channel steel or H-beam of sufficient strength according to the diameter of the underground structure. The support beam 801 is made into a long frame shape with supports installed inside the frame to increase the strength of the support beam 801. The walkway 804 is made of 3mm thick checkered plate. Construction workers can walk on the crossbeam frame 8 through the walkway 804 to inspect or adjust the material feeding component 2. The rope ladder 803 provides a convenient passage for personnel to enter and exit the foundation pit. The railing 802 effectively prevents falls from height and ensures the safety of construction workers.

[0066] like Figure 3 As shown, the monitoring component 6 includes a display 601 located outside the foundation pit and a camera 602 located inside the foundation pit. The display 601 is placed on a stable support and a temporary dustproof shed is erected. There are generally two cameras 602, which are symmetrically fixed at the end of the material unloading component 3 to monitor the entire pouring process.

[0067] The concrete is received from the concrete mixer truck by the feeding assembly 2 and transferred to the unloading assembly 3. The unloading assembly 3 then further transfers the concrete to the feeding assembly 4, which distributes the concrete evenly into the support assembly 1 along the circumference of the foundation pit. During the pouring process, the concrete delivered to the pouring area is vibrated by the vibration assembly 5 to form the pool wall 7. The entire process is monitored and recorded in real time by the monitoring assembly 6 to ensure the construction quality.

[0068] Example 2

[0069] Based on Example 1, in order to solve the problems of high labor intensity, low efficiency, and uneven vibration in traditional manual vibration, such as... Figures 1-2 , Figure 4 , Figures 13-14As shown, the vibrating assembly 5 includes a vibrating unit and a second annular track 510 for guiding the vibrating unit to slide along the circumference of the foundation pit, so as to uniformly vibrate the concrete in the pouring area in sequence along the circumference.

[0070] The second circular track 510 is fixedly installed on the top of the perimeter edge railing 802 of the foundation pit. It is made of C-shaped steel into arc-shaped short sections, and several arc-shaped short sections are assembled together to form the second circular track 510.

[0071] The vibration unit includes a support slider 501 disposed within the second annular track 510, and a support rod 502 fixedly disposed on the top of the support slider 501. The support rod 502 is provided with multiple sets of guide pulleys 503. A support plate is fixedly disposed on the side of the support rod 502 away from the foundation pit. A take-up wheel 504 and a motor 505 for driving the take-up wheel 504 to rotate are provided on the support plate. A suspension line 506 is wound on the take-up wheel 504. The suspension line 506 passes through multiple sets of guide pulleys 503 in sequence and a vibrator 507 is attached to its end. A vibrating rod 508 is provided at the output end of the vibrator 507. A push rod 509 for pushing the vibration assembly 5 to move along the second annular track 510 is also fixedly disposed on the support plate.

[0072] After the concrete pouring is completed, the vibrating assembly 5 is started to vibrate the concrete. The motor 505 drives the take-up wheel 504 to rotate, and controls the suspension line 506 to pull the vibrator 507 up and down. After being guided by the guide pulley 503, the suspension line 506 drives the vibrator 508 to insert into the concrete and pull it out, realizing continuous vibration of the concrete. During the vibration process, the construction personnel can adjust the speed of the motor 505 in real time according to the concrete pouring height, control the vibration depth and frequency, and ensure the concrete density and structural quality. The construction personnel push the support slider 501 to slide at a uniform speed along the second circular track 510 through the push rod 509, so that the vibrating assembly 5 runs around the circumference of the foundation pit.

[0073] Example 3

[0074] Based on Embodiments 1 and 2, the present invention also provides a method for pouring concrete for the wall panels of a large underground circular structure, comprising the following steps:

[0075] S1. In the foundation pit of the circular structure, the support assembly 1 and the feeding assembly 4 are erected along the circumference. The crossbeam frame 8 is laid across the foundation pit. The feeding assembly 2 is placed in the wheel groove 805 of the crossbeam frame 8. The unloading assembly 3 is fixedly installed at the bottom of the support beam 801 of the crossbeam frame 8. The vibrating assembly 5 is placed on the railing 802 of the crossbeam frame 8.

[0076] S2. Reverse the concrete mixer truck to the vicinity of the feeding assembly 2 and rotate its discharge chute so that the discharge chute outlet is directly above the feed end of the feeding assembly 2, ensuring that the concrete can be smoothly introduced into the feeding system.

[0077] S3. Concrete flows sequentially from the discharge chute of the concrete mixer truck into the feeding chute 201 of the feeding assembly 2, and then enters the feeding chute 401 of the feeding assembly 4 through the discharge hopper 301 and the adjustable discharge pipe 302 of the discharge assembly 3, and is finally evenly distributed in the pouring area within the support assembly 1.

[0078] S4. When the concrete pouring height reaches the set height, the limit plate 409 in the limit unit triggers the limit switch 408. The limit switch 408 sends a control signal to the drive component of the track wheel 405, driving the track wheel 405 to move the feeding assembly 4 forward along the first circular track 407. When the limit plate 409 leaves the concrete surface, the limit switch 408 resets, the drive component is de-energized, the feeding assembly 4 stops moving, and continues to pour the next section. The above process is repeated until the concrete placement operation of the entire wall panel is completed.

[0079] S5. During the concrete pouring process, the vibrator 508 of the vibrating component 5 is inserted into the concrete of the poured section to improve the concrete density. After the concrete pouring and vibration operation of the entire pouring area is completed, a circular structure pool wall 7 with complete structure and stable quality is finally formed.

[0080] During the pouring and vibration process, the operation of each component is remotely monitored by monitoring component 6.

[0081] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
