Description

Technical Field

[0001] This invention relates to the field of warehousing system technology, specifically to a bulk material storage and transportation system and its construction method. Background Technology

[0002] Silos, as large bulk material storage structures widely used in power, cement, metallurgy, grain, and port industries, have always had their structural safety, economy, and functionality as core considerations in design and research. Traditional silo structures are mainly divided into two categories: supported silos and ground-mounted flat-bottom silos. However, both of these mainstream structures have significant technical limitations and economic shortcomings in engineering practice.

[0003] Supported silos typically use concrete or steel frames to support the silo body and the load of the full load in the air, with a conical funnel at the bottom for unloading. This structure has a complex support structure and high cost. The lower support structure (columns, ring beams, and supports, etc.) must withstand enormous loads, requiring large reinforced concrete sections or large amounts of steel, leading to a significant increase in material and construction costs. The complex node construction also increases design and construction difficulty. The load transmission path is indirect, requiring a circuitous route through "silo body → support structure → foundation." Under seismic loads, the support structure becomes a weak point, requiring additional reinforcement and high seismic design requirements, further increasing costs. Furthermore, space utilization and functionality are limited. While the space between the support structures is usable, it is often constrained by structural layout, and a high clearance is still required below the conical funnel to accommodate conveying equipment, resulting in a relatively high overall elevation of the building above the silo, making it susceptible to significant wind and seismic loads.

[0004] While ground-mounted flat-bottomed silos, which rest directly on a ring foundation, eliminate the need for a lower supporting structure and thus have lower costs, traditional designs, often with flat or shallow conical bottoms, present unloading challenges. Flat-bottom designs prevent materials from flowing entirely by gravity, necessitating expensive cleaning machinery or complex multi-point unloading systems. Shallow conical bottoms, while providing a slope, suffer from a small cone angle, leading to unloading blockages and incomplete unloading, requiring auxiliary unloading devices with limited improvement in effectiveness. Therefore, neither flat nor shallow conical bottoms can achieve reliable gravity unloading. Ground-mounted flat-bottomed silos also present stability challenges. Their resistance to horizontal forces (especially slippage and overturning under seismic loads) relies primarily on the friction of the foundation and the depth of the foundation. In soft soil or high-seismic-intensity areas, extensive pile foundations or massive raft foundations are often required, negating the economic advantages. Furthermore, this structure lacks maintenance access; the enclosed bottom area lacks necessary space for material transport and structural maintenance, resulting in insufficient functionality.

[0005] Therefore, the current silo structure field faces a prominent contradiction: supported silos have complete functions but poor economy and seismic performance; ground-mounted flat-bottom silos have good economy but have defects in function and stability.

[0006] Therefore, to solve the above problems, a bulk material storage and transportation system and construction method are needed that can reduce construction costs and construction period, have significant economic advantages, and at the same time improve the structure's anti-slip, anti-overturning and seismic performance, ensuring the safe and stable use of equipment in complex geological and high-intensity areas. Summary of the Invention

[0007] In view of this, the purpose of this invention is to overcome the defects in the prior art and provide a bulk material storage and transportation system and construction method. By arranging the bottom ring beam, the bottom plate, and the underground corridor within the foundation and rigidly connecting them, a bottom system with synergistic load-bearing capacity is formed, allowing the silo body to sit directly on it, thereby eliminating the need for traditional high-altitude support, significantly reducing costs and construction time, and possessing significant economic advantages. At the same time, the controllable opening and closing unloading port connects the silo body and the underground corridor, and in conjunction with the silo top input and corridor output equipment, the integrated operation of gravity unloading and mechanized transportation is realized. Furthermore, the overall structure relies on the "tenon" anchoring effect of the underground corridor embedded in the soil, significantly improving the anti-slip, anti-overturning, and seismic performance, ensuring the safe and stable use of the equipment in complex geological and high-intensity seismic areas.

[0008] The bulk material storage and transportation system of the present invention includes a silo body located on top of a foundation and a bottom ring beam, a bottom plate, and an underground corridor located within the foundation for supporting the silo body on the foundation; the silo body and the underground corridor are connected by a controllable opening and closing unloading port;

[0009] It also includes a material input device located at the top of the silo body for feeding materials into the silo body, and a material unloading device located at the bottom of the discharge port of the underground corridor for sending materials from the silo body to the material output device, through which the discharge port is controlled to open or close.

[0010] Furthermore, the underground corridor and the warehouse floor are rigidly connected.

[0011] Furthermore, the top slab of the underground corridor and the bottom slab of the warehouse are an integral structure.

[0012] Furthermore, the underground corridor is a precast structural component with connecting bars embedded in its top; the bottom slab is cast in place and rigidly connected to the connecting bars.

[0013] Furthermore, the bottom of the silo bottom ring beam is supported by ring beam piles.

[0014] Furthermore, the bottom of the underground corridor is supported by silo piles.

[0015] Furthermore, the underground corridor is supported by a load-bearing member located in the middle of the width direction of the underground corridor.

[0016] Furthermore, the underground corridor is approximately located in the middle of the width of the silo body, and the unloading port is located on the top plate of the underground corridor; the silo body has a discharge surface that slopes towards the unloading port.

[0017] Furthermore, the silo body is provided with several silos along the length of the underground corridor.

[0018] This solution also discloses a construction method based on the aforementioned bulk material storage and transportation system, including the following steps:

[0019] S1: Pile foundation construction;

[0020] S2: Excavation of the foundation pit for the underground corridor, and pouring of the underground corridor floor slab and side walls;

[0021] S3: The underground corridor roof slab, the bottom ring beam at the bottom of the silo body, and the bottom slab at the bottom of the silo body are poured continuously in one go;

[0022] S4: The wall of the silo during construction;

[0023] S5: Hoisting and installing buildings and equipment on the construction site and installing equipment in the underground corridor.

[0024] The beneficial effects of this invention are as follows: The bulk material storage and transportation system disclosed in this invention, through a bottom bearing system composed of a silo bottom slab, a silo bottom ring beam, and an underground corridor arranged within the foundation, allows the silo body and materials inside to be directly transferred to the foundation through this bottom bearing system. The force transmission path is simplified to silo body to foundation, eliminating the traditional frame-supported structure with poor seismic performance, thus significantly reducing construction costs. Furthermore, eliminating the frame-supported structure can also lower the overall elevation of the silo, thereby reducing the height of the building above the silo, reducing wind load and seismic action on the silo body, and effectively weakening the whiplash effect of the building above the silo under seismic action. This solution also utilizes the tight embedding effect of the silo bottom ring beam and the underground corridor with the foundation to significantly enhance anti-slip, anti-overturning, and seismic performance: the underground corridor and the silo bottom ring beam are integrally connected through the silo bottom slab to form a seamless rigid structure. The underground corridor embedded in the soil acts as a "tenon" anchoring key, relying on passive earth pressure and sidewall friction to synergistically resist horizontal loads, making the overall structure's horizontal bearing capacity significantly better than that of traditional silo structures. The silo body, silo floor slab, silo floor ring beam and underground corridor work together to achieve efficient transfer of vertical and horizontal loads, effectively reduce the length and number of piles to optimize the pile foundation design, and the spatial structure design of the underground corridor integrates unloading, conveying and maintenance functions, significantly reducing project costs and shortening the construction period while ensuring structural safety.

Detailed Implementation

[0029] Figure 1 This is a schematic diagram of the structure of the present invention. Figure 2 This is a schematic diagram of the stress structure of the present invention. Figure 1 As shown, the bulk material storage and transportation system in this embodiment includes a silo body 1 located on top of the foundation, and a bottom ring beam 2, a bottom slab 11, and an underground corridor 3 located within the foundation to support the silo body 1. The bottom ring beam 2, the bottom slab 11, and the underground corridor 3 are rigidly connected, and the underground corridor 3 and the bottom ring beam 2 are integrally connected by the bottom slab 11 to form a seamless rigid structure. This rigid connection includes at least that the top slab of the underground corridor 3 and the bottom slab 11 are cast-in-place integral structures; or, the underground corridor 3 is a precast structural component with connecting bars embedded in its top, and the bottom slab 11 is cast-in-place and rigidly connected to the connecting bars. The rigid connection between the bottom ring beam 2 and the bottom slab 11 is typically achieved by integral cast-in-place concrete. The bottom ring beam 2, the bottom slab 11, and the underground corridor 3 are all located within the foundation, with the silo body 1 resting on the bottom slab 11, and its bottom supported by the bottom ring beam 2. The bottom ring beam 2, bottom slab 11, and underground corridor 3 form an integrated structure, collectively constituting the bottom load-bearing system. When materials are stored in the silo, the vertical loads of the materials are mainly transferred directly to the foundation through the bottom slab 11 and the connected underground corridor 3, while the self-weight of the silo walls is transferred to the foundation through the bottom ring beam 2, significantly reducing the construction costs required for traditional overhead support structures. Furthermore, eliminating the frame support structure lowers the overall elevation of the silo, thereby reducing the height of the building above the silo, reducing wind load and seismic effects on the silo body 1, and effectively mitigating the whiplash effect of the building above the silo under seismic action. By utilizing the tight embedding effect between the silo bottom ring beam 2, silo bottom slab 11, and underground corridor 3 and the foundation, the silo's resistance to sliding and overturning is significantly enhanced. The integral pile-raft foundation formed by the silo bottom ring beam 2, silo bottom slab 11, and underground corridor 3 directly spreads the load to a large area of ​​foundation soil, which can effectively control uneven settlement of the foundation, especially suitable for soft soil areas, and achieves a comprehensive improvement in structural safety and stability.

[0030] In this embodiment, the bottom ring beam 2, the bottom slab 11, and the top slab of the underground corridor 3 are cast-in-place integral structures. This integrated design not only eliminates construction joints and enhances the overall integrity and impermeability, but also significantly improves the overall stiffness of the bottom area, making the transmission of vertical and horizontal loads more continuous and uniform. The underground corridor 3, embedded in the soil, acts as a "tenon" anchoring key, using passive earth pressure and sidewall friction to resist horizontal loads, and together with the bottom ring beam 2, enhances the overall structure's resistance to sliding and overturning.

[0031] In this embodiment, the silo body 1 and the underground corridor 3 are connected by a controllable opening and closing discharge port; the underground corridor 3 is used to accommodate the material output device 9 during use, so as to transport the material discharged from the discharge port to a preset position. The synergy between the silo body 1, the bottom ring beam 2, and the underground corridor 3 in this solution realizes the efficient transmission of vertical and horizontal loads in the overall structure.

[0032] In this embodiment, the bottom of the silo bottom ring beam 2 is supported by ring beam piles 4. The silo bottom ring beam 2 also functions as a pile cap, transferring the load to the deep bearing layer through the ring beam piles 4. This allows the ring beam piles 4 to effectively improve the vertical bearing capacity and control uneven settlement when this solution is applied to soft soil foundations or scenarios with strict settlement control requirements.

[0033] In this embodiment, the bottom of the underground corridor 3 is supported by silo piles 5, which bear the weight of the underground corridor 3 itself, the internal equipment, and the material load on the top slab of the underground corridor 3. At the same time, since the underground corridor 3 is deeply buried in the foundation, its pile top elevation is relatively low, which can effectively save pile length while ensuring the use effect, thereby controlling construction costs.

[0034] In this embodiment, the bottom piles 5 and the ring beam piles 4 work together to bear the vertical and horizontal loads of the corridor area and the ring beam area, respectively. Together with the underground corridor 3 embedded in the soil and the bottom ring beam 2, they form an integrated lateral force resisting system, jointly resisting horizontal loads and overturning moments. Utilizing the enormous constraint force of the surrounding soil, the silo is provided with resistance to horizontal slippage and overturning moments far exceeding those of traditional friction foundations, thereby significantly improving the overturning resistance and seismic performance of the silo structure. At the same time, the pile-raft foundation formed by the bottom ring beam 2, the bottom slab 11, and the underground corridor 3 can take into account the pile-soil interaction, which is conducive to leveraging the group pile effect and significantly reducing foundation costs while ensuring support reliability.

[0035] In this embodiment, the sidewalls of the underground corridor 3 are in close contact with the foundation soil after construction. Under horizontal loads, the passive earth pressure and friction force generated by the foundation soil on the sidewalls, as well as the horizontal reaction force of the base plate 11 and the bottom plate of the underground corridor 3, together provide anti-slip and anti-overturning capabilities far exceeding those of traditional friction foundations, significantly reducing the horizontal load borne by the pile foundations and effectively reducing the dependence on the number of pile foundations. This significantly improves the stability and safety of the structure under horizontal loads, ensuring the long-term reliable operation of the silo under complex geological conditions such as soft soil foundations. Furthermore, the thickness of the sidewalls of the underground corridor 3 can be set to remain constant from top to bottom or gradually increase, preferably gradually increasing from top to bottom, to optimize the design, save engineering work, and ensure its structural safety under passive earth pressure.

[0036] In this embodiment, the side walls or ends of the underground corridor 3 are also reserved with maintenance entrances and exits, so that the underground corridor 3 can also serve as a functional space structure to provide unloading space, material transportation channel and maintenance space. In addition, the long and straight underground corridor 3 facilitates the flexible installation and layout of facilities such as water supply and drainage, ventilation and power supply in the warehouse, which helps to reduce the amount of auxiliary facility installation work and significantly reduce the project cost while ensuring structural safety.

[0037] In this embodiment, Figure 2 In the diagram, F represents the horizontal load acting on the silo (such as wind load and seismic action). R1 ​​is the horizontal reaction force of the foundation soil on the pile foundation (including the silo bottom pile 5 and the ring beam pile 4), used to restrain the displacement of the bottom of the structure; R2 is the passive earth pressure of the foundation soil on the side wall of the underground corridor 3, providing the structure with anti-slip and anti-overturning moment far exceeding that of traditional friction foundations, significantly improving the overall anti-overturning capacity; R3 is the frictional force of the foundation soil on the bottom slab of the underground corridor 3 and the silo bottom slab 11, providing the foundation with anti-slip capacity, and together with R1 and R2, forming a complete horizontal load transfer path, further enhancing the overall stability of the structure under horizontal action.

[0038] Under horizontal load F, this design integrates multiple lateral force resistance lines, combining base friction, passive earth pressure on the side walls, and pile foundation constraint. These lines work collaboratively, with the pile foundation and underground corridor continuously providing resistance. Combined with the frictional force of the ground-mounted structure, the overall structure exhibits superior seismic performance. Especially in soft soil foundations or high-intensity seismic areas, traditional structures struggle to achieve sufficient frictional force. This design's composite force system fundamentally solves the problem of insufficient lateral force resistance in traditional ground-mounted silos, achieving a balance between economy and high safety.

[0039] In this embodiment, the discharge port is located on the top plate of the underground corridor 3, and the silo body 1 has a discharge surface 6 inclined towards the discharge port, with the discharge port located at the lower position of the discharge surface 6. This allows the material to be concentrated at the discharge port entirely by gravity, thus eliminating the need for mechanical cleaning, reducing equipment investment and energy consumption, while ensuring thorough unloading and continuous discharge, avoiding the residue problem of flat-bottomed silos. The discharge surface 6 can be an inclined surface, a conical surface, or a funnel surface, etc., arranged according to the actual situation, preferably to achieve the function of guiding the material to the discharge port, which will not be elaborated further here.

[0040] In this embodiment, the underground corridor 3 is approximately located in the middle of the width of the silo body 1, and there are multiple discharge ports distributed near both sides of the underground corridor 3 in the width direction. Taking two discharge ports as an example, the two discharge ports are symmetrically arranged on both sides of the underground corridor 3 in the horizontal direction, which improves discharge efficiency and ensures uniform stress on the silo bottom, avoiding uneven loading and reducing uneven settlement. The pouring surface 6 inside the silo body 1 corresponds to the two discharge ports, forming two independent conical funnel-shaped pouring sections. The discharge ports are connected to the pouring sections one-to-one, and the discharge ports are located at the bottom of the pouring sections to ensure reliable material distribution and smooth discharge. More specifically, as shown in the figure, the cross-section of the pouring surface 6 is "W"-shaped, with its two horizontal sides extending upwards and connecting to the inner walls of the corresponding sides of the silo body 1, further ensuring pouring reliability. Corresponding to the two discharge ports, a set of material output devices 9 is arranged at the bottom of each discharge port to further improve material handling efficiency.

[0041] In this embodiment, the underground corridor 3 is supported by a load-bearing member 7, which is located in the middle of the width of the underground corridor 3. As a structural support, the load-bearing member 7 effectively improves the load-bearing capacity of the top slab of the underground corridor 3 and enhances the overall structural strength of the underground corridor 3, making it less deformed and more stable when subjected to upper loads and horizontal forces. The load-bearing member 7 can be a wall, structural column, or other form of support structure, preferably serving the function of supporting the underground corridor 3, which will not be elaborated further here. In this solution, the load-bearing member 7 is a concrete-cast wall, which has high structural reliability.

[0042] In this embodiment, the bulk material storage and transportation system further includes a material input device 8 located at the top of the silo body 1 for feeding materials into the silo body 1, a material output device 9 located in the underground corridor 3 for conveying materials discharged from the discharge port to a preset position, and a discharge device 10 located at the bottom of the discharge port in the underground corridor for conveying materials from the silo body 1 to the material output device 9. The discharge port is opened or closed by the discharge device 10. The material input device 8, discharge device 10, and material output device 9 can all be selected from existing technologies to achieve their intended functions. For example, the material input device 8 can be a conveying device with a spiral chute; the discharge device 10 can be a vibrating feeder with a controlled discharge function; and the material output device 9 can be a closed belt conveyor. Further details are omitted here. Through the automatic control of the discharge device 10, the discharge port can be opened and closed as needed, thus forming a complete integrated storage, unloading, and transportation system. This system has advantages such as high automation, minimal manual intervention, and dust-free closed conveying, meeting environmental protection requirements.

[0043] In this embodiment, several silo bodies 1 are arranged along the length of the underground corridor 3. Multiple silo bodies 1 share the same underground corridor 3, which allows for the unified arrangement of material output equipment 9, material input equipment 8, and unloading equipment 10, achieving centralized transportation and unified scheduling, thereby significantly reducing the number of equipment and civil engineering work, and lowering construction and operating costs.

[0044] This solution also discloses a construction method based on the aforementioned bulk material storage and transportation system, including the following steps:

[0045] S1: Construction of pile foundations (including bottom piles 5 and ring beam piles 4).

[0046] S2: Excavation of the foundation pit for the underground corridor, followed by pouring of the bottom slab and side walls of underground corridor 3. After the side walls of underground corridor 3 are constructed to the structural elevation of the bottom of the storage area, the soil around underground corridor 3 is backfilled and compacted to the design elevation of the structural bottom, forming a construction platform. This backfilling and compaction step ensures close contact between the side walls of the underground corridor and the foundation soil, providing a reliable lateral force resisting foundation for the structure.

[0047] S3: The top slab of the underground corridor 3, the bottom ring beam 2 located at the bottom of the silo body, and the bottom plate 11 located at the bottom of the silo body 1 are poured continuously in one go to ensure that the bottom foundation structure of the silo and the silo body form a rigid integrated structure.

[0048] S4: The walls of the silo body 1 are constructed from bottom to top using slipform or climbing formwork techniques.

[0049] S5: Hoist the construction structure and equipment on the warehouse and install the equipment in the underground corridor 3; wherein the warehouse structure includes at least a cover, the warehouse equipment includes at least a material input device 8, and the equipment in the underground corridor 3 includes at least a material unloading device 10 and a material output device 9.

[0050] Compared to traditional supported silo bottom structures, this scheme reduces the number of supporting ring beams, supporting columns, and supporting walls, directly saving significant construction costs. It eliminates the need for a pre-constructed high-altitude supporting frame, allowing construction to begin directly from the foundation, improving safety and significantly shortening the overall construction period. Traditional supported silo bottom supporting walls require double rows of piles to share bending moments, resulting in a wider foundation for the supporting wall ring beam. In contrast, this scheme's ground-mounted silo structure utilizes the bottom ring beam 2, the bottom slab 11, and the underground corridor 3 to share bending moments, enabling a single row of piles for the bottom ring beam 2. This significantly reduces the number of piles and the cross-section of the bottom ring beam 2, making construction relatively easier and cost-effective.

[0051] Compared with existing technologies, this solution has the following significant advantages:

[0052] I. Significant economic benefits

[0053] 1) Directly saves a lot of construction costs: By directly eliminating the entire complex under-storage support structure (including support columns, support ring beams, support wall cylinders and complex nodes), and optimizing the design of the under-storage ring beam 2, the corresponding amount of steel or concrete can be saved, and the material cost is greatly reduced.

[0054] 2) Simplified construction and shorter construction period: The simplified structural system directly reduces the number of construction procedures. There is no need to first construct a high-altitude support frame at the bottom of the structure; construction can begin directly from the foundation, improving construction safety and significantly shortening the overall construction period, indirectly reducing management and financial costs.

[0055] 3) Optimize the foundation soil and foundation cost: The "tenon" or "anchor key" effect formed by the underground corridor 3 greatly enhances the structure's resistance to lateral displacement and overturning; at the same time, the pile raft foundation formed by the bottom ring beam 2, the bottom slab 11 and the underground corridor 3 is conducive to giving full play to the pile group effect; thus, the diameter, length or number of piles can be effectively reduced. In areas with soft foundation soil or high seismic fortification requirements, this saving is particularly considerable.

[0056] 4) Compact spatial layout of underground corridor 3: This scheme is conducive to reducing ventilation and power supply facilities. The long and straight side walls of underground corridor 3 facilitate the flexible installation and layout of water supply, drainage, ventilation, power supply and other facilities in the warehouse.

[0057] II. Comprehensive Improvement in Structural Performance and Safety

[0058] 1) Direct load transmission path and high structural reliability: The "integrated lower anchor body" design changes the load transmission path from the traditional multi-level transmission to direct transmission, eliminating the weak links in the intermediate support structure and making the structural system more reliable and reasonable.

[0059] 2) Fundamentally solves the problem of horizontal bearing capacity: The "tenon" structure embedded in the foundation soil utilizes the enormous constraint force of the surrounding soil to provide the silo with resistance to horizontal slippage and overturning moment far exceeding that of traditional friction foundations, significantly reducing the horizontal load borne by the pile foundation and effectively reducing the dependence on the number of piles. At the same time, the pile-raft foundation formed by the silo bottom ring beam 2, the silo bottom slab 11, and the underground corridor 3 can take into account the interaction between piles and soil, which is conducive to leveraging the group pile effect.

[0060] 3) Reduce the load on the warehouse building: The space required under the warehouse is placed underground, which reduces the height of the factory building on the warehouse roof. This directly reduces the climbing height of material input equipment and buildings, while also reducing the wind load and seismic action on the buildings. The design of the components of the superstructure is more economical, resulting in the optimization of the entire system.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
