Description

Technical Field

[0001] This invention belongs to the field of grain warehouse construction technology, and more specifically, relates to a device and method for pouring concrete for the raised floor slab and warehouse floor of a shallow circular silo. Background Technology

[0002] The concrete pouring operation of the raised floor slab and floor of the shallow circular silo presents a series of unique and complex construction challenges. After the main structure of the shallow circular silo is completed, the enclosed space of the silo roof directly restricts the use of large-scale pouring equipment. Truck-mounted concrete pumps, due to their large size and the need for external operating space, cannot enter the silo or operate through the opening in the silo roof. This renders the traditional pouring method relying on truck-mounted concrete pumps completely ineffective, and only ground-mounted pumps can be used to complete the concrete delivery and pouring.

[0003] At the same time, the structural characteristics of the shallow circular silo further exacerbated the construction difficulties: on the one hand, the area of ​​the raised floor slab is huge, and the coverage of traditional ground pump pipes is limited. To complete the full pouring, the position of the ground pump pipes needs to be moved frequently, and each move is accompanied by a cumbersome installation and dismantling process; on the other hand, the silo floor is divided into multiple independent areas by the partition walls of the raised floor. These areas are isolated from each other and the passages are narrow. The layout of the ground pump pipes needs to be adapted to the shape and size of different areas, which further increases the frequency of pipe adjustments.

[0004] In traditional concrete pumping methods, construction workers need to repeatedly disassemble and reassemble the pump pipes to adapt to different pouring areas and ranges. This is not only extremely labor-intensive, but each disassembly and reassembly also requires a significant amount of time for positioning, connection, and fixation, severely slowing down the construction progress. More importantly, frequent disassembly and reassembly can easily lead to poor sealing at the pump pipe connections, increasing the risk of grout leakage and affecting the quality of concrete pouring. At the same time, repeated movement of equipment and adjustment of pipelines may also damage the surface of the poured concrete, requiring later repairs, further increasing construction costs and timelines.

[0005] In addition, since the elevated floor and the warehouse floor are at different heights, the traditional method often requires phased pouring - first complete the pouring of the elevated floor slab, and then pour the warehouse floor after it reaches a certain strength. This step-by-step construction mode prolongs the overall construction period. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a concrete pouring device and method for the raised floor slab and floor surface of a shallow circular silo. In the pouring assembly, concrete is diverted to two sets of horizontal pump pipes via a three-way connector, with dual gate valves controlling their on / off states. Combined with the adjustment assembly, synchronous pouring of the raised floor slab and floor surface of the shallow circular silo is achieved, effectively improving construction efficiency. A winch in the adjustment assembly provides power, and with the traction and hooking of steel wire ropes and chains, the length, angle, and position of the horizontal pump pipes can be mechanically adjusted. This solves the problem of heavy, difficult-to-move concrete-filled pump pipes during pouring, enabling simultaneous pouring and adjustment, further improving pouring efficiency. Simultaneously, the first rotary joint grants the horizontal pump pipes rotational freedom, and its length design expands the coverage area. The flexible pump pipes compensate for the dimensional difference between the fixed number of pump sections and the unloading port, reducing the number of disassembly and assembly operations and further expanding the pouring range.

[0007] To achieve the above objectives, according to one aspect of the present invention, a shallow circular silo overhead floor slab and silo floor concrete pouring device is provided, comprising a hanger assembly, an adjustment assembly, and a pouring assembly; wherein, the hanger assembly is located at the top of the grain inlet of the silo, the adjustment assembly and the pouring assembly are located inside the shallow circular silo, and the pouring assembly is connected to the hanger assembly through the adjustment assembly. The hanger assembly includes a base, columns, support plates, and a central crossbeam. The base is located at the top of the grain inlet of the silo and is a square frame. Columns are fixedly installed at the four corners of the base. A central crossbeam is fixedly installed between the columns on two opposite faces. Support plates are fixedly installed on the two central crossbeams near both ends. The adjustment assembly includes a first winch and a second winch. The first winch and the second winch are respectively fixedly installed on the top of the support plate. The output end of the first winch is wound with a first winch wire rope, and the other end of the first winch wire rope is fixedly installed with two first winch hook chains. The output end of the second winch is wound with a second winch wire rope, and the other end of the second winch wire rope is fixedly installed with two second winch hook chains. The pouring assembly includes a horizontal ground pump pipe. A first 90-degree elbow is fixedly installed at one end of the horizontal ground pump pipe, and a vertical ground pump pipe is fixedly installed at the other end of the first 90-degree elbow. A first rotary joint is fixedly installed at the other end of the vertical ground pump pipe, and a tee joint is fixedly installed at the other end of the first rotary joint. Multiple first horizontal ground pump pipes are provided at the lateral end of the tee joint, and a second 90-degree elbow is fixedly installed at the vertical end of the tee joint. Multiple second horizontal ground pump pipes are provided at the other end of the second 90-degree elbow.

[0008] Furthermore, the hanger assembly also includes an upper connecting beam, an upper crossbeam, diagonal braces, and limiting baffles. An upper connecting beam is fixedly installed between the tops of every two columns, and diagonal braces are fixedly installed between the columns on the other two opposite faces. An upper crossbeam is fixedly installed between two parallel upper connecting beams, and two opposing limiting baffles are provided at the top center of the upper crossbeam.

[0009] Furthermore, the adjustment assembly also includes a first suspension wire rope and a second suspension wire rope, one end of which is fixedly connected to the upper crossbeam via a wire rope buckle, and the first suspension wire rope and the second suspension wire rope are located between two limit baffles.

[0010] Furthermore, the other end of the first suspension wire rope is attached to the middle of the first horizontal pump pipe, and the other end of the second suspension wire rope is attached to the middle of the second horizontal pump pipe. The two first winches with hooked chains are respectively hooked to the midpoints of the first and second sections of the first horizontal pump pipe at the end of the first horizontal pump pipe, and the two first winches with hooked chains are respectively hooked to the midpoints of the first and second sections of the second horizontal pump pipe at the end of the second horizontal pump pipe.

[0011] Furthermore, the casting assembly also includes a first gate valve and a second gate valve. The first gate valve is fixedly installed between the lateral end of the tee joint and the first horizontal pump pipe, and the second gate valve is fixedly installed between the second 90-degree elbow and the second horizontal pump pipe.

[0012] Furthermore, when the length of the first horizontal pump pipe with a fixed number of sections does not match the position of the unloading port, a soft pump pipe is fixedly installed at the other end of the first horizontal pump pipe, and two first winch hook chains are respectively hooked to the end of the soft pump pipe and the end of the last section of the first horizontal pump pipe. When the length of the second horizontal pump pipe with a fixed number of sections does not match the position of the unloading port, a soft pump pipe is fixedly installed at the other end of the second horizontal pump pipe, and two second winch hook chains are respectively hooked to the end of the soft pump pipe and the end of the last section of the second horizontal pump pipe.

[0013] According to a second aspect of the present invention, a method for pouring concrete for the raised floor slab and floor of a shallow circular silo is provided, which is implemented using the aforementioned concrete pouring device for the raised floor slab and floor of a shallow circular silo, and includes the following steps: S100: When pouring the warehouse floor, start pouring from the unloading port that is farther away from the center of the shallow circular warehouse. Push the first horizontal pump pipe on the overhead layer and let the first horizontal pump pipe rotate around the first rotary joint. Adjust the angle of the first horizontal pump pipe so that the pipe opening of the first horizontal pump pipe is aligned with the unloading port on the bottom plate of the overhead warehouse, and let the concrete flow from the unloading port onto the warehouse floor. S200: After the pouring of this area is completed, the length of the first horizontal pump pipe is adjusted, and the first section of the first horizontal pump pipe, which is hooked by the first winch with a hook chain, is removed so that it is adjusted from a horizontal state to a vertical state. S300: Empty the concrete from the first horizontal pump pipe, then use the first winch to remove the first section of the first horizontal pump pipe and move it aside for later use. Next, continue to hook the first winch with the hook chain in the middle of the third section of the first horizontal pump pipe, and then pour concrete. After the area is poured, continue to dismantle the pipe sections of the first horizontal pump pipe and repeat the above operation until the concrete pouring on the floor is completed. S400: When pouring the bottom slab of the elevated warehouse, start pouring from a place far away from the center of the shallow circular warehouse. Push the second horizontal pump pipe and let the second horizontal pump pipe rotate around the second rotary joint. The position of the outlet of the second horizontal pump pipe also changes continuously on the bottom slab of the elevated warehouse. S500: By adjusting the length of the second horizontal pump pipe, the first section of the second horizontal pump pipe, which is hooked by the hook chain of the second winch, is removed, so that it is adjusted from a horizontal state to a vertical state. S600: Empty the concrete from the second horizontal pump pipe, then use the second winch to remove the first section of the second horizontal pump pipe and move it aside for later use. Next, continue to hook the second winch with the hook chain in the middle of the third section of the second horizontal pump pipe, and then pour concrete. After the area is poured, continue to dismantle the pipe sections of the second horizontal pump pipe and repeat the above operation until the concrete pouring of the bottom plate of the silo is completed.

[0014] Furthermore, during the pouring process, when the second horizontal pump pipe is pushed to rotate around the second rotary joint to adjust the angle, the second horizontal pump pipe must always avoid the suspension steel wire rope of the first horizontal pump pipe.

[0015] Furthermore, when one horizontal pump pipe needs to temporarily stop pouring while the other horizontal pump pipe needs to continue pouring, the gate valve corresponding to the horizontal pump pipe that needs to be suspended is closed so as not to affect the normal pouring of the other horizontal pump pipe.

[0016] Furthermore, during the concrete pouring process on the floor of the storage chamber, an anti-pollution curtain is placed at the supporting partition wall corresponding to the discharge position to prevent cement splashed during pouring from contaminating the surface of the supporting partition wall.

[0017] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The shallow circular silo raised floor slab and silo floor concrete pouring device of the present invention, through the three-way joint, first gate valve, second gate valve, first horizontal pump pipe and second horizontal pump pipe in the pouring component, the three-way joint realizes the concrete diversion, so that the concrete can flow to two sets of horizontal pump pipes at the same time. The two gate valves control the opening and closing of the two sets of pump pipes respectively, ensuring that the silo floor slab and silo floor at different heights can receive concrete independently; the two sets of horizontal pump pipes correspond to the pouring areas of the raised silo floor slab and silo floor respectively. With the adjustment of the component, synchronous operation is finally realized, which solves the problem that the raised floor slab and silo floor of the shallow circular silo cannot be poured at the same time, and achieves the simultaneous pouring of the raised floor slab and silo floor of the shallow circular silo, thus improving the construction efficiency.

[0018] 2. The shallow circular silo overhead base plate and silo ground concrete pouring device of the present invention, by adjusting the first winch, second winch, first suspension wire rope, second suspension wire rope, first winch hook chain and second winch hook chain in the components, the winch provides power, and through the traction and hooking of the wire rope and chain, the length adjustment (disassembly of pipe section), angle deflection and position movement of the horizontal ground pump pipe can be realized. The whole process does not require manual handling, and completes the mechanized operation. It solves the problem that the ground pump pipe filled with concrete is heavy and cannot be moved during the concrete pouring process. It enables the adjustment of the position of the ground pump pipe while pouring concrete, thus improving the pouring efficiency.

[0019] 3. The shallow circular silo overhead base plate and silo floor concrete pouring device of the present invention, through the first rotary joint, gives the horizontal pump pipe the freedom to rotate around the axis. With the design of the first horizontal pump pipe and the second horizontal pump pipe, a larger area can be covered by rotation. The soft pump pipe, with its flexibility, compensates for the size difference between the fixed number of pump pipe sections and the unloading port, reduces the number of disassembly and assembly, and further expands the coverage area of ​​the pouring.

[0020] 4. The shallow circular silo overhead base plate and silo floor concrete pouring device of the present invention is fixedly connected to the pouring component by the other ends of the first and second suspension steel wire ropes. Through the coordinated cooperation with the first winch hook chain and the second winch hook chain, a multi-point suspension system for the pouring component is formed, which effectively distributes the weight of the pouring component, reduces the load-bearing pressure at a single point, and makes the adjustment process more stable and precise by the auxiliary traction of the suspension steel wire ropes when the winch drives the pouring component to adjust its position. This further improves the stability of the pouring component during operation and ensures that it can efficiently complete the synchronous pouring task of the silo base plate and silo floor.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0026] In this patent, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0027] Example 1 like Figure 1-6 As shown in the figure, this invention provides a concrete pouring device for the bottom slab and floor of a shallow circular silo, including a hanger assembly, an adjustment assembly, and a pouring assembly. The hanger assembly is located at the top of the grain inlet 1 of the silo. The adjustment assembly and the pouring assembly are located inside the shallow circular silo, and the pouring assembly is connected to the hanger assembly via the adjustment assembly. The position of the pouring assembly is adjusted using the adjustment assembly, enabling the pouring assembly to simultaneously complete the concrete pouring of the bottom slab and floor of the shallow circular silo. This invention solves the problem that the bottom slab and floor of a shallow circular silo cannot be poured simultaneously, achieving simultaneous pouring of the bottom slab and floor of the shallow circular silo, improving construction efficiency. The adjustment assembly also solves the problem of manually moving and fixing the horizontal pump pipe length and the flexible hose at the end of the horizontal pump pipe, allowing mechanical adjustment of the pump pipe length and fixing of the pump pipe outlet to be done.

[0028] like Figure 2As shown, the hanger assembly includes a base 9, a column 10, a support plate 11, an upper connecting beam 12, a middle crossbeam 13, an upper crossbeam 14, a diagonal brace 15, and a limiting baffle 16. The base 9 is located at the top of the grain inlet 1 on the top of the silo. It is a square frame. Columns 10 are fixedly installed at the four corners of the base 9. An upper connecting beam 12 is fixedly installed between the tops of every two columns 10. A middle crossbeam 13 is fixedly installed between the columns 10 on two opposite faces. Diagonal braces 15 are fixedly installed between the columns 10 on the other two opposite faces. Support plates 11 are fixedly installed near both ends on the two middle crossbeams 13. An upper crossbeam 14 is fixedly installed between the two parallel upper connecting beams 12. Two opposing limiting baffles 16 are provided at the top center of the upper crossbeam 14. The base 9, as a square frame, provides a stable foundation for the entire component. Together with the columns 10 at the four corners, it forms a three-dimensional support structure. The interconnection of the upper connecting beams 12, middle crossbeams 13, and diagonal braces 15 ensures that all components work closely together, greatly improving the overall load-bearing capacity and deformation resistance of the hanger component. It can stably support the weight of the adjustment component and the pouring component, ensuring that the construction accuracy is not affected by structural shaking or displacement during the pouring operation. Secondly, the support plate 11 provides convenient placement and fixing points for the installation and adjustment components, eliminating the need for additional temporary support structures and simplifying the construction layout; the limiting baffle 16 at the top of the upper beam 14 can restrict the position of the adjustment components, preventing them from shifting due to vibration or external force during the pouring operation, ensuring the stable operation of the adjustment components and the pouring components, and reducing construction interruptions or errors caused by component displacement.

[0029] Furthermore, the base 9 is slightly larger than the grain inlet 1 on the top of the silo, so that the hanger assembly can be stably installed on the grain inlet 1 on the top of the silo. By increasing the contact area and distributing the force, the installation shaking problem caused by improper matching of the base and the grain inlet size is effectively avoided.

[0030] like Figure 1 and Figure 3As shown, the adjustment assembly includes a first winch 17, a second winch 18, a first suspension wire rope 19, a second suspension wire rope 20, a first winch wire rope 21, a second winch wire rope 22, a first winch hook chain 23, and a second winch hook chain 24. The first winch 17 and the second winch 18 are respectively fixedly installed on the top of the support plate 11. The output end of the first winch 17 is wound with the first winch wire rope 21, and the other end of the first winch wire rope 21 is fixedly installed with two first winch hook chains 23. The output end of the second winch 18 is wound with a second winch wire rope 24. The second winch wire rope 22 has two second winch hook chains 24 fixedly installed at the other end. The first winch hook chain 23 and the second winch hook chain 24 are both hooked to the casting component. The first winch 17 and the second winch 18 serve as power sources and can provide stable driving force. With the transmission and connection of the first winch wire rope 21, the second winch wire rope 22, the first winch hook chain 23, and the second winch hook chain 24, the length and position of the casting component can be adjusted to ensure that the casting component can adapt to the structure of the shallow circular silo and meet the requirement of simultaneous casting of the silo bottom plate and the silo ground. This mechanized adjustment method replaces traditional manual operation, saving a lot of labor costs, reducing the labor intensity of workers, and making construction more labor-saving and efficient. On the other hand, the precise control capability ensures that the pouring components are always in the optimal working position, improving the accuracy and uniformity of concrete pouring, reducing rework caused by positional deviations, thereby accelerating the construction progress, improving the overall construction quality, and enhancing the flexibility and adaptability of construction.

[0031] Furthermore, the adjustment assembly also includes a first suspension wire rope 19 and a second suspension wire rope 20. One end of the first suspension wire rope 19 and the second suspension wire rope 20 are fixedly connected to the upper crossbeam 14 through wire rope clips. The first suspension wire rope 19 and the second suspension wire rope 20 are located between two limiting baffles 16 to limit the sliding of the first suspension wire rope 19 and the second suspension wire rope 20, thereby ensuring that the suspension wire ropes remain stable during operation and avoiding positional deviation of the casting assembly due to swaying or slippage of the wire ropes.

[0032] Furthermore, the other ends of the first suspension wire rope 19 and the second suspension wire rope 20 are fixedly connected to the casting component. Through their coordinated cooperation with the first winch hook chain 23 and the second winch hook chain 24, they together form a multi-point suspension system for the casting component. This effectively distributes the weight of the casting component, reduces the load-bearing pressure at a single point, and allows for a smoother and more precise adjustment process when the winch drives the casting component to adjust its position. This further enhances the stability of the casting component during operation, ensuring that it can efficiently complete the synchronous casting of the bottom plate and the ground surface of the silo.

[0033] like Figure 5-6 As shown, the casting assembly includes a horizontal ground pump pipe 35. One end of the horizontal ground pump pipe 35 extends out of the shallow circular silo's overhead layer and connects to the concrete conveying device. The other end is fixedly installed with a first 90-degree elbow 31. The other end of the first 90-degree elbow 31 is fixedly installed with a vertical ground pump pipe 25. The vertical ground pump pipe 25 extends above the overhead silo's bottom plate 4 through the unloading port 3 at the center of the bottom plate 4. The other end of the vertical ground pump pipe 25 is fixedly installed with a first rotary joint 26. The other end of the first rotary joint 26 is fixedly installed with a tee joint 27. The lateral end of the tee joint 27 is fixedly installed with a first gate valve 30. The other end of the first gate valve 30 is fixedly installed with multiple first horizontal ground pump pipes 29.

[0034] Furthermore, a second 90-degree elbow 31 is fixedly installed at the vertical end of the tee connector 27, a second gate valve 33 is fixedly installed at the other end of the second 90-degree elbow 31, and a plurality of second horizontal pump pipes 34 are fixedly installed at the other end of the second gate valve 33.

[0035] Specifically, the ground-level horizontal pump pipe 35 serves as the initial channel for concrete delivery. One end is connected to the concrete delivery device to stably receive concrete, while the other end uses a first 90-degree elbow 31 to change the delivery direction, transforming the concrete delivery from horizontal to vertical. The vertical pump pipe 25 extends above the floor slab 4 via the unloading port 3 at the center, providing delivery paths for different height areas within the silo (especially above the floor slab). The first rotary joint 28 provides flexibility for subsequent pipe rotation, facilitating adjustments to the pouring direction. The tee joint 27 diverts concrete flow, with its horizontal end controlling the opening and closing and flow rate of the first horizontal pump pipe 29 via a first gate valve 30. The vertical end of the tee joint 27 changes the delivery direction via a second 90-degree elbow 32, working in conjunction with a second gate valve 33 to control the concrete delivery of the second horizontal pump pipe 34. This further expands the pouring range vertically, precisely covering more areas within the shallow circular silo, especially the complex space between the ground and the floor slab.

[0036] The tight connection of each pipe and joint ensures the sealing of the concrete delivery, significantly reducing grout leakage and improving material utilization. The combination of the first 90-degree elbow 31, the second 90-degree elbow 32, and the tee joint 27 allows the concrete to flexibly switch delivery paths in multiple horizontal and vertical directions, perfectly adapting to the synchronous pouring requirements of the shallow circular silo ground and the elevated base slab, providing solid structural support for integrated construction. The first rotary joint 28 enhances the convenience of pipe adjustment, allowing the pouring range to flexibly change with the circular structure of the silo, avoiding pouring dead zones. The first gate valve 30 and the second gate valve 33 can accurately control the delivery of the corresponding horizontal pump pipes, facilitating the adjustment of the pouring rhythm according to the construction progress of different areas, preventing concrete accumulation or insufficient supply, and significantly improving pouring efficiency. The setting of multiple sets of horizontal pump pipes greatly expands the coverage area of ​​a single pour, reduces the number of equipment relocations, further ensures the stability of construction quality, and makes the entire pouring process more efficient and precise.

[0037] Furthermore, the other end of the first suspension wire rope 19 is attached to the middle of the first horizontal pump pipe 29, and the other end of the second suspension wire rope 20 is attached to the middle of the second horizontal pump pipe 34. Two first winch hook chains 23 are respectively hooked to the midpoints of the first and second sections of the first horizontal pump pipe 29, and two first winch hook chains 24 are respectively hooked to the midpoints of the first and second sections of the second horizontal pump pipe 34. The wire ropes attached to the middle of the pump pipes provide a balanced upward pull, effectively balancing the weight of the pump pipes and the load during concrete transport, preventing deformation such as bending and sagging due to uneven stress. The chains hooked to the midpoints of the pump pipe ends allow for precise control of the stress at the pipe ends. Combined with the suspension effect of the wire ropes, this ensures the entire horizontal pump pipe remains stable during operation, reducing swaying caused by vibration or load changes, and providing a solid foundation for stable concrete transport. This multi-point, symmetrical suspension and hook design works in synergy with the winch of the adjustment components. When the winch winds up or unwinds the wire rope or chain, the angle, height, and extension direction of the horizontal pump pipe can be precisely controlled by adjusting the tension at different points. This allows the pump pipe to flexibly adapt to the circular structure of the shallow circular silo and the needs of different pouring areas, easily covering every corner of the silo floor and ground, avoiding any dead corners during pouring.

[0038] Furthermore, the lengths of the first horizontal pump pipe 29 and the second horizontal pump pipe 34 are less than the radius of the shallow circular silo, which facilitates the pouring of concrete for the silo bottom plate and the silo floor.

[0039] Example 2 like Figure 4As shown in the figure, an embodiment of the present invention provides another shallow circular silo overhead base plate and silo floor concrete pouring device. In this embodiment, all other contents are the same as in Embodiment 1. The only difference from Embodiment 1 is that when the length of the fixed number of first horizontal pump pipes 29 does not match the position of the unloading port 3, a soft pump pipe 36 is fixedly installed at the other end of the first horizontal pump pipe 29. Two first winch hook chains 23 are respectively hooked to the end of the soft pump pipe 36 and the end of the last section of the first horizontal pump pipe 29. When the length of the fixed number of second horizontal pump pipes 34 does not match the position of the unloading port 3, a soft pump pipe 36 is fixedly installed at the other end of the second horizontal pump pipe 34. Two second winch hook chains 24 are respectively hooked to the end of the soft pump pipe 36 and the end of the last section of the second horizontal pump pipe 34. The outlet of the soft pump pipe 36 is aligned with the appropriate unloading port 3, and concrete is poured onto the warehouse floor 6 through the unloading port 3. At the same time, an anti-pollution curtain is placed at the supporting partition wall 7 corresponding to the discharge position to prevent the cement splashed during pouring from contaminating the surface of the supporting partition wall 7.

[0040] The soft pump pipe 36 has good flexibility and bendability, which can flexibly compensate for the length difference between the fixed number of pump pipe sections and the unloading port 3. Compared with the traditional method of adjusting the length by increasing or decreasing the number of rigid pump pipe sections, the soft pump pipe 36 does not require frequent disassembly and assembly of rigid pipes. It can quickly adapt to the position requirements of different unloading ports 3, greatly reducing the construction interruption time caused by size mismatch and improving the adaptability to complex warehouse layouts.

[0041] Example 3 Combination Figure 1-6 ,like Figure 7 As shown, the present invention provides a method for pouring concrete for the raised bottom slab and floor of a shallow circular silo, which is implemented using the aforementioned concrete pouring device for the raised bottom slab and floor of a shallow circular silo. The specific steps are as follows: S100: When pouring the silo floor 6, first pour from the unloading port that is farther away from the center of the shallow circular silo. Push the first horizontal pump pipe 29 on the elevated layer and let the first horizontal pump pipe 29 rotate around the first rotary joint 26. Adjust the angle of the first horizontal pump pipe 29 so that the pipe opening of the first horizontal pump pipe 29 is aligned with the unloading port 3 on the silo floor plate of the elevated layer, and let the concrete flow from the unloading port onto the silo floor 6. S200: After the pouring of the area is completed, the length of the first horizontal pump pipe 29 is adjusted, and the first section of the first horizontal pump pipe 29 hooked by the first winch hook chain 23 is removed, so that it is adjusted from a horizontal state to a vertical state. S300: Empty the concrete from the first horizontal pump pipe 29, then remove the first section of the first horizontal pump pipe 29 by controlling the first winch 17 and move it to the side for later use. Next, continue to hook the first winch with the hook chain 23 to the middle of the third section of the first horizontal pump pipe 29, and then pour concrete. After the area is poured, continue to disassemble the pipe sections of the first horizontal pump pipe 29 and repeat the above operation until the concrete pouring of the floor 6 is completed. S400: When pouring the bottom plate 4 of the elevated warehouse, start pouring from a place far away from the center of the shallow circular warehouse. Push the second horizontal pump pipe 34 and let the second horizontal pump pipe 34 rotate around the second rotary joint 28. The position of the outlet of the second horizontal pump pipe 34 also changes continuously on the bottom plate 4 of the elevated warehouse. S500: By adjusting the length of the second horizontal pump pipe 34, the first section of the second horizontal pump pipe 34, which is hooked by the hook chain 24 of the second winch, is removed, so that it is adjusted from a horizontal state to a vertical state. S600: Empty the concrete from the second horizontal pump pipe 34, then use the second winch 18 to remove the first section of the second horizontal pump pipe 34 and move it aside for later use. Next, continue to hook the second winch with the hook chain 24 to the middle of the third section of the second horizontal pump pipe 34, and then pour concrete. After the area is poured, continue to dismantle the pipe sections of the second horizontal pump pipe 34 and repeat the above operation until the concrete pouring of the bottom plate 4 of the elevated warehouse is completed.

[0042] Furthermore, during the pouring process, when the second horizontal pump pipe 34 is rotated around the second rotary joint 28 to adjust its angle, the second horizontal pump pipe 34 must always avoid the suspension steel cable of the first horizontal pump pipe 29. This effectively prevents collisions and entanglement between the second horizontal pump pipe 34 and the suspension steel cable of the first horizontal pump pipe 29. If the two come into contact, the tension or impact force from the rotation of the pump pipe may damage the suspension steel cable, affecting its suspension stability over the first horizontal pump pipe 29, and even causing safety accidents such as the pump pipe falling. Maintaining the avoidance state ensures the integrity of the suspension system and pump pipe structure, reducing safety risks during construction. Furthermore, when one horizontal pump pipe needs to temporarily stop pouring while the other needs to continue, closing the gate valve corresponding to the pump pipe requiring temporary cessation of pouring ensures that the normal pouring of the other pump pipe is not affected, enabling independent operation control of the two pump pipes. When one pump pipe needs to be paused due to completion of the pouring area, equipment adjustment, or other reasons, closing the corresponding gate valve directly cuts off the concrete delivery to that pump pipe, while the other pump pipe can continue pouring undisturbed. This eliminates the need to stop the entire pouring system, avoiding overall construction stagnation caused by the cessation of a single pump pipe, minimizing wasted time, ensuring construction progresses according to plan, and significantly improving overall operational efficiency. Closing the gate valve effectively prevents waste caused by concrete overflow or backflow in the paused pump pipe.

[0043] Furthermore, during the concrete pouring process of the silo floor 6, an anti-pollution curtain is placed at the supporting partition wall 7 corresponding to the discharge position to prevent cement splashed during pouring from contaminating the wall surface of the supporting partition wall 7.

[0044] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
