Description

Technical Field

[0001] This invention relates to the field of prefabricated foundation construction for mixing plants on soft soil, specifically the foundation of powder tanks in mixing plants for soft geological conditions. Background Technology

[0002] Soft foundations refer to foundations primarily composed of silt, silty soil, fill, miscellaneous fill, or other highly compressible soil layers. Areas with soft foundations have poor geological conditions, low bearing capacity, and are difficult to stabilize during later settlement.

[0003] Existing foundation construction for mixing plants on soft soil typically employs reinforced concrete piles in conjunction with large-volume concrete foundations. This method is cumbersome, costly, time-consuming, and non-recyclable, resulting in significant resource waste. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that require mixing plants to be built on weak foundations. Due to poor geological conditions, weak bearing capacity, and a high probability of settlement, these mixing plants face construction difficulties and are not recyclable. This invention provides a foundation for mixing plant powder silos on weak geological surfaces. By changing the point support method to a surface support method, the support force is effectively dispersed and the support stability is improved, thereby enhancing the bearing capacity. Furthermore, it can be disassembled after use, achieving the purpose of recyclability.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] The mixing plant powder tank is located on a foundation in a weak geological environment. It includes several foundation modules and the mixing plant. Reinforcing beams are fixed on the foundation modules. The mixing plant is supported by the foundation modules. The foundation modules are in planar contact with the ground. The foundation modules are evenly distributed around the mixing plant. Side support rods are provided above the foundation modules. One end of the side support rod is hinged to the foundation module, and the other end is hinged to the mixing plant.

[0007] Currently, due to construction needs, soft foundations also need to be effectively utilized. When building a mixing plant on a soft foundation, due to the enormous weight of the mixing plant, a large amount of reinforced concrete is used for foundation construction to avoid collapse. However, the disadvantages of reinforced concrete are that it cannot be reused indefinitely, and the construction process is complex. The final load-bearing capacity mainly depends on the material strength and construction quality. Existing technologies have high construction costs, long construction periods, and are not recyclable, resulting in a large waste of resources.

[0008] This invention employs several foundation modules as the supporting foundation of the mixing plant. By distributing the bearing capacity across the surface of the foundation modules, point stress is avoided, thereby improving the supporting capacity of the weak foundation. Furthermore, the foundation modules are evenly distributed around the mixing plant, ensuring that the mixing plant receives multi-directional supporting forces. This further disperses the load exerted by the mixing plant on the foundation modules, resulting in lower single-point loads and enhanced bearing capacity. The side support rods, through their assistance, increase the number of stress points, thereby adding more foundation modules and effectively increasing the bearing area of ​​the weak geological structure. The expanded bearing area further enhances the overall bearing capacity. The single-point load is further reduced, thereby enhancing the load-bearing capacity. The foundation modules and side support rods serve as the load-bearing base, and the components used are detachable, allowing for recycling and reuse, effectively reducing resource waste. In this invention, the foundation modules change the single-point load-bearing form for the mixing plant load to a form of several independent surface load-bearing forms, effectively dispersing the load. The side support rods increase the number of foundation modules, thereby increasing the load-bearing area and making the load dispersion more thorough. This load dispersion enhances the load-bearing capacity and improves support stability.

[0009] Furthermore, the foundation module includes a combined steel platform, and several evenly distributed steel pipe piles are provided below the combined steel platform, with inter-pile I-beams fixed between the steel pipe piles.

[0010] In this invention, the combined steel platform serves as the main support, effectively distributing the load to the ground. Furthermore, the steel pipe piles, through embedding into the ground, effectively enhance the overturning resistance of the combined steel platform. The I-beams between the piles effectively resist the shear stress on the combined steel platform, thereby ensuring the stability of the foundation module.

[0011] Furthermore, the combined steel platform includes two layers of thick steel plates, with inter-plate I-beams fixed between the thick steel plates;

[0012] The axes of the I-beams between the plates all point towards the mixing plant.

[0013] The combined steel platform in this invention has its bottom surface in direct contact with the ground, which can effectively distribute the load. The stacking of two layers of thick steel plates can effectively prevent settlement from making the foundation module impossible to disassemble. Furthermore, the connection of the I-beams between the plates can effectively reduce the weight of the foundation module while enhancing the load-bearing capacity. Orienting the axis of the I-beams between the plates toward the mixing plant can effectively enhance the resistance to shear stress and avoid local overload of the I-beams.

[0014] Furthermore, the side support rod includes a hydraulic telescopic rod, with a first hydraulic connection cavity fixed at one end of the hydraulic telescopic rod near the foundation module, and a second hydraulic connection cavity fixed at one end of the hydraulic telescopic rod near the mixing station;

[0015] A first floating ball joint is provided in the first hydraulic connection cavity, and the first floating ball joint is fixed to the foundation module. A second floating ball joint is provided in the second hydraulic connection cavity, and the second floating ball joint is fixed to the mixing station.

[0016] In this invention, the first and second hydraulic connecting cavities can effectively adjust the support capacity of the side support rods for the mixing plant through hydraulic control. The hydraulic telescopic rods can change their length through hydraulic changes, thereby adapting to the distance between the mixing plant and the foundation module. The first and second floating ball joints can not only change the support angle of the side support rods for the mixing plant through the ball joints, but also effectively achieve shock absorption through the floating of the ball joints. Through the floating ability of the first and second floating ball joints, the impact of vibration can be effectively offset at the hinge point through floating buffer when affected by an earthquake, thereby enhancing the earthquake resistance of this invention.

[0017] Furthermore, a first connecting pipe is provided on the side of the first hydraulic connection cavity, and adjacent first hydraulic connection cavities are connected through the first connecting pipe;

[0018] The second hydraulic connection chamber is provided with a second connecting pipe on its side, and adjacent second hydraulic connection chambers are connected through the second connecting pipe.

[0019] In this invention, the first hydraulic chambers are all interconnected, thereby stabilizing the pressure within the first hydraulic chambers. If the side support rod encounters excessive external force, it can be transmitted to all foundation modules through the interconnected first hydraulic chambers, thus avoiding excessive load on a single point. After the second hydraulic chambers are interconnected, they can be balanced by oil pressure at the connection point with the mixing plant, preventing the weight of the mixing plant from tilting in one direction, effectively protecting the position of the mixing plant and preventing it from tipping over.

[0020] Furthermore, it also includes a first hydraulic cylinder, and several of the first hydraulic connection chambers are connected to the first hydraulic cylinder after being connected together;

[0021] It also includes a second hydraulic cylinder, and several second hydraulic connection chambers are connected to the second hydraulic cylinder.

[0022] In this invention, the hydraulic oil in the first hydraulic chamber is connected to the first hydraulic cylinder, and the hydraulic oil in the second hydraulic connection chamber is connected to the second hydraulic cylinder. By setting the first and second hydraulic cylinders, the oil pressure in the first and second hydraulic connection chambers is kept stable. Since the mixing station is heavy, the change in force is large when the force changes. The first and second hydraulic cylinders can effectively provide pressure balance of the hydraulic oil and alleviate the impact caused by rapid changes in external force, thereby improving the stability of the side support rod and enhancing the load-bearing capacity of the side support rod.

[0023] Furthermore, the first floating ball hinge includes a hinged steel ball, the hinged steel ball is partially embedded in the first hydraulic connection cavity, a floating diaphragm is provided outside the portion of the hinged steel ball embedded in the first hydraulic connection cavity, and a plurality of uniformly distributed steel balls are provided between the floating diaphragm and the hinged steel ball.

[0024] The structure of the second floating ball joint is the same as that of the first floating ball joint.

[0025] The first floating ball joint in this invention achieves the purpose of adapting to the force changes of the articulated steel ball through a floating diaphragm. The floating diaphragm can separate the hydraulic oil and the articulated steel ball, and can also use the pressure changes of the hydraulic oil to effectively support the articulated steel ball. Furthermore, the floating diaphragm is not connected to the articulated steel ball. Through the intermediate contact of the steel ball, the articulated steel ball can change the sliding friction to rolling friction, effectively improving the floating load-bearing capacity while avoiding affecting the angle change at the joint.

[0026] Furthermore, the hydraulic telescopic rod includes a sleeve that can split in the middle, and an isolation tube is provided inside the sleeve. One end of the isolation tube is connected to the first hydraulic connection cavity, and the other end is connected to the second hydraulic connection cavity.

[0027] The middle section of the isolation tube is provided with a corrugated section, which can freely expand and contract.

[0028] In this invention, by adjusting the pressure of the hydraulic oil in the isolation pipe, the stretching or contraction of the corrugated section is controlled, thereby increasing the adaptability range of the side support rod in this invention. Furthermore, since a sleeve is provided outside the isolation pipe, the isolation pipe is protected from direct contact with the outside world, thus effectively extending the service life of the isolation pipe. The pressure of the hydraulic oil in the isolation pipe is determined by the injection of hydraulic oil into the first hydraulic connection cavity and the second hydraulic connection cavity.

[0029] Furthermore, adjacent foundation modules can be detached and fixedly connected.

[0030] In this invention, by detachably fixing adjacent foundation modules, the load-bearing surfaces of the foundation modules can be effectively combined to prevent settlement when a single foundation module is subjected to large external forces. The detachable fixing of the foundation modules also makes it convenient to disassemble after use, which improves the overall load-bearing capacity without affecting the reuse of the foundation modules.

[0031] Furthermore, the foundation modules are arranged in a ring around the mixing plant, and the connection points of the side support rods with the mixing plant are evenly distributed with the center of gravity of the mixing plant as the center.

[0032] In this invention, the foundation modules are arranged in a ring-shaped distribution, which makes the position distribution of the foundation modules and the mixing plant more uniform and the stress more uniform.

[0033] In summary, the present invention has the following advantages compared with the prior art:

[0034] (1) The foundation module described in this invention changes the form of single-point load bearing of the mixing plant to a form of several independent surface bearing, effectively dispersing the load. The number of foundation modules is increased by side support rods to increase the bearing area, making the load dispersion more thorough. By dispersing the load, the bearing capacity is enhanced and the support stability is improved.

[0035] (2) By connecting the I-beams between the plates, the present invention can effectively reduce the weight of the foundation module and enhance the load-bearing capacity. By aligning the axis of the I-beams between the plates with the mixing plant, the resistance to shear stress can be effectively enhanced and local overload of the I-beams can be avoided.

[0036] (3) The first floating ball hinge in this invention achieves the purpose of adapting to the force change of the hinged steel ball through the floating diaphragm. The floating diaphragm can separate the hydraulic oil and the hinged steel ball, and can also use the pressure change of the hydraulic oil to achieve the function of effectively supporting the hinged steel ball.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0047] Example:

[0048] like Figures 1 to 7 As shown, the foundation of the mixing plant's powder tank in a weak geological environment includes several foundation modules 1 and a mixing plant 4. A reinforcing beam 3 is fixed on the foundation module 1. The mixing plant 4 is supported by the foundation module 1. The foundation module 1 is in planar contact with the ground. The foundation modules 1 are evenly distributed around the mixing plant 4. A side support rod 2 is provided above the foundation module 1. One end of the side support rod 2 is hinged to the foundation module 1, and the other end is hinged to the mixing plant 4.

[0049] Adjacent foundation modules 1 can be detached and fixedly connected.

[0050] The foundation module 1 is distributed in a ring around the mixing station 4, and the connection points of the side support rods 2 and the mixing station 4 are evenly distributed with the center of gravity of the mixing station 4 as the center.

[0051] This embodiment uses several foundation modules 1 as the supporting foundation of the mixing plant 4. By distributing the bearing capacity across the surface of the foundation modules 1, the stress on the ground is prevented from forming a single stress point, thereby improving the supporting capacity of the weak foundation. In this embodiment, the foundation modules 1 are evenly distributed around the mixing plant 4, so that the mixing plant 4 is subjected to multi-directional supporting forces, making the load applied by the mixing plant 4 to the foundation modules 1 more dispersed, thus reducing the single-point load and enhancing the bearing capacity. The side support rods 2 can increase the stress points through the assistance of the rods, thereby increasing the number of foundation modules 1 and effectively increasing the bearing area of ​​the weak geological surface. After the bearing area is expanded, the single-point load will be further reduced, thereby enhancing the bearing capacity. Since the foundation modules 1 and the side support rods 2 are used as the bearing foundation, the components used are disassembled and can be recycled and reused, effectively reducing the waste of resources.

[0052] In this embodiment, the reinforcing beam 3 can effectively enhance the deformation resistance of the foundation module 1, so that the surface stress mode of the foundation module 1 will not change during use, thereby enhancing the stability of this embodiment.

[0053] In this embodiment, the detachable fixed connection is fastened with bolts. The foundation module 1 forms several minor arcs around the center of gravity of the mixing station 4. The annular enclosure formed by these minor arcs increases the stress-bearing area while ensuring uniform stress distribution on the foundation module 1. This avoids tilting problems caused by uneven local stress distribution when too many foundation modules 1 are connected to form a large whole. In this embodiment, the foundation module 1 can support the weight of the mixing station 4 and the load of the powder tank 6. Furthermore, a conveyor belt is built on the mixing station 4 to distribute the mixing work and material storage, thereby improving storage efficiency and achieving the purpose of weight distribution.

[0054] Based on this, the foundation module 1 includes a combined steel platform, and several evenly distributed steel pipe piles 13 are provided below the combined steel platform, with inter-pile I-beams 14 fixed between the steel pipe piles 13.

[0055] The combined steel platform includes two layers of thick steel plates 11, and an inter-plate I-beam 12 is fixed between the thick steel plates 11.

[0056] The axes of the I-beams 12 between the plates all face the mixing plant 4.

[0057] In practical application, this embodiment uses steel pipe piles 13 driven into the ground as a foundation to prevent displacement of the combined steel platform. The combined steel platform also increases the contact area for stress distribution, preventing subsidence of the foundation module 1 due to weak geological conditions. In this embodiment, the H-beams 14 between the piles effectively improve the stability of the steel pipe piles 13, preventing tilting of the foundation module 1 due to displacement of the steel pipe piles 13.

[0058] The side support rod 2 includes a hydraulic telescopic rod 24. The end of the hydraulic telescopic rod 24 near the foundation module 1 is fixed with a first hydraulic connection cavity 23, and the end of the hydraulic telescopic rod 24 near the mixing station 4 is fixed with a second hydraulic connection cavity 27.

[0059] A first floating ball joint 22 is provided in the first hydraulic connection cavity 23, and the first floating ball joint 22 is fixed to the foundation module 1. A second floating ball joint 26 is provided in the second hydraulic connection cavity 27, and the second floating ball joint 26 is fixed to the mixing station 4.

[0060] The first hydraulic connection cavity 23 is provided with a first connecting pipe 21 on its side, and adjacent first hydraulic connection cavities 23 are connected through the first connecting pipe 21;

[0061] The second hydraulic connection cavity 27 is provided with a second connecting pipe 25 on its side, and adjacent second hydraulic connection cavities 27 are connected through the second connecting pipe 25.

[0062] It also includes a first hydraulic cylinder, and several of the first hydraulic connection chambers 23 are connected to the first hydraulic cylinder after being connected together;

[0063] It also includes a second hydraulic cylinder, and several second hydraulic connection chambers 27 are connected to the second hydraulic cylinder after being connected together.

[0064] The first floating ball hinge 22 includes a hinged steel ball 221, which is partially embedded in the first hydraulic connection cavity 23. A floating diaphragm 222 is provided outside the portion of the hinged steel ball 221 embedded in the first hydraulic connection cavity 23. A plurality of uniformly distributed steel balls 223 are provided between the floating diaphragm 222 and the hinged steel ball 221.

[0065] The structure of the second floating ball joint 26 is the same as that of the first floating ball joint 22.

[0066] The hydraulic telescopic rod 24 includes a sleeve 241 that can be split in the middle, and an isolation tube 243 is provided inside the sleeve 241. One end of the isolation tube 243 is connected to the first hydraulic connection cavity 23, and the other end is connected to the second hydraulic connection cavity 27.

[0067] The middle part of the isolation tube 243 is provided with a corrugated section 242, which can freely expand and contract.

[0068] In this embodiment, the pressure in the first hydraulic connection chamber 23 and the second hydraulic connection chamber 27 can be kept stable by adjusting the first hydraulic cylinder and the second hydraulic cylinder as a whole. Furthermore, the amount of hydraulic oil in the side support rod 2 can be effectively adjusted by the first hydraulic cylinder and the second hydraulic cylinder, thereby achieving the purpose of floating adjustment of the support capacity according to the actual situation. This can not only avoid damage caused by excessive pressure, but also enhance the adaptability of this embodiment to different mixing plants 4.

[0069] Since the hydraulic oil in the first hydraulic chamber is connected to the first hydraulic cylinder, and the hydraulic oil in the second hydraulic connection chamber 27 is connected to the second hydraulic cylinder, the oil pressure in the first hydraulic connection chamber 23 and the second hydraulic connection chamber 27 is kept stable due to the arrangement of the first and second hydraulic cylinders. Since the mixing station 4 is heavy, the change in force is large when the force changes. The first and second hydraulic cylinders can effectively provide pressure balance of the hydraulic oil and alleviate the impact caused by rapid changes in external force, thereby improving the stability of the side support rod 2 and enhancing the load-bearing capacity of the side support rod 2.

[0070] In this embodiment, the adjustable capability of hydraulic oil is utilized to set the ball joint as a floating ball joint. This not only effectively adjusts the rotation of the ball joint but also significantly improves its adaptability to vibration, thereby greatly enhancing the stability of this embodiment. When supporting heavy structures such as the mixing plant 4, it also has good adaptability and can adapt to various stress changes in the mixing plant 4. By adapting to stress changes, the impact of stress changes on weak geological conditions can be effectively avoided, thus enabling this embodiment to provide stronger support, avoid the generation of excessive construction waste, and improve the environmental friendliness and construction quality of this embodiment.

[0071] In this embodiment, a floating diaphragm 222 is used as a spacer between the hydraulic oil and the articulated steel ball 221. While using the hydraulic oil as a support, it can also effectively adapt to the compression of the steel ball 223 and the articulated steel ball 221. It can enhance the buffering capacity while providing support. When the first floating ball hinge 22 and the second floating ball hinge 26 are impacted, the buffering of the hydraulic oil can directly act on the articulated steel ball 221, thereby making the side support rod 2 return to stability in the first time.

[0072] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
