Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically a foundation system for a storage tank in a concrete mixing plant. Background Technology

[0002] Large-scale infrastructure projects such as railways, highways, municipal works, and water conservancy projects are characterized by their large scale and tight schedules, resulting in a huge demand for concrete with high quality requirements. Concrete mixing plants, as core facilities ensuring concrete supply and quality, directly impact the overall project schedule and cost due to their installation speed, stability, and economic efficiency. Among these, the storage tanks of the mixing plant, as key components for storing bulk raw materials such as cement and fly ash, are characterized by high load-bearing capacity, high center of gravity, and sensitivity to foundation settlement; therefore, the design and construction of their foundations are particularly crucial.

[0003] The existing monolithic concrete spread foundation is a shallow foundation that spreads the load of the superstructure to the ground through a monolithically cast reinforced concrete slab. Its construction requires a large amount of steel bars and concrete, which not only has a long construction period and high material consumption, but also makes it difficult to design and construct according to the independent stress characteristics of each storage tank leg, thus making it difficult to achieve the optimal load distribution. Utility Model Content

[0004] The purpose of this invention is to provide a foundation system for a concrete mixing plant storage tank to solve the above-mentioned problems.

[0005] The technical solution of this utility model is: A foundation system for a concrete mixing plant storage tank includes multiple foundation units and multiple transverse connectors, wherein the foundation units are connected into a whole by the transverse connectors; each foundation unit includes: a vertical force transmission system, including pile foundations and pile caps disposed on top of the pile foundations; a storage tank support system, including supports disposed on the pile caps and embedded parts pre-embedded in the top of the supports; an adjustable platform assembly connected to the embedded parts for adjusting the distance between the platform assembly and the embedded parts, thereby adjusting the installation elevation of the top of the adjustable platform assembly; and transverse connectors, the two ends of which are respectively connected to the pile caps of two adjacent foundation units, so that the multiple foundation units form an integral load-bearing frame.

[0006] Furthermore, the transverse connector is a prefabricated component that can be detachably connected, used to connect adjacent pile caps.

[0007] Furthermore, the transverse connector is either a steel beam or a prestressed concrete beam, and both ends of the transverse connector are connected to the pile cap in a load-transferable manner.

[0008] Furthermore, the transverse connecting member is a steel beam, and both ends of the transverse connecting member are connected to the pile top cap by high-strength bolts or welding.

[0009] Furthermore, the transverse connector is a prestressed concrete beam, and the reinforcing bars at both ends of the transverse connector extend into the adjacent pile cap. The reinforcing bar skeleton of the transverse connector is connected to the reinforcing bar skeleton of the pile cap, so that the transverse connector and the pile cap are integrally formed as a reinforced concrete structure.

[0010] Furthermore, the pile foundation is a prestressed concrete pipe pile.

[0011] Furthermore, the pile foundation is made of steel pipe piles, and the steel pipe piles are detachably connected to the pile cap of the steel beam structure.

[0012] Furthermore, the embedded part is a first trapezoidal block with an isosceles trapezoidal structure. The lower base of the first trapezoidal block is embedded in the concrete of the support pier. Both trapezoidal surfaces of the first trapezoidal block are equipped with first fixing plates having through holes. The adjustable platform assembly includes: a second trapezoidal block, with the same structure as the first trapezoidal block, symmetrically arranged above the first trapezoidal block, and a second fixing plate on the second trapezoidal block; a support, arranged on the lower base of the second trapezoidal block, for connecting the legs of the storage tank; and two first threaded rods, respectively arranged on both sides of the first trapezoidal block, with both ends of each first threaded rod passing through the first fixing plate. The first threaded rod is provided with a locking nut at the position of the first fixed plate and the second fixed plate. Two trapezoidal push blocks are provided between the inclined surfaces of the first trapezoidal block and the second trapezoidal block on the same side. The two inclined surfaces of each trapezoidal push block are slidably connected to the inclined surfaces of the first trapezoidal block and the second trapezoidal block, respectively. A through channel is provided along the thickness direction of each trapezoidal push block. The second threaded rod is provided with its two ends passing through the through channels of the two trapezoidal push blocks, and the ends of the second threaded rod protrude from the through channels. Locking thread sleeves are provided on the exposed parts at both ends of the second threaded rod.

[0013] Furthermore, the number and layout of the basic units are matched with the number and position of the storage tank legs.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention provides a single support leg for each foundation unit, decomposing the monolithic foundation into multiple independent foundation units. This enables precise design and construction, and the units are then connected into a unified load-bearing frame via transverse connectors. This significantly improves the overall rigidity, stability, and overturning resistance of the foundation system, effectively resisting horizontal and accidental loads. Furthermore, each foundation unit ensures the safe and effective transfer of tank loads to the deep foundation through a vertical force transmission path from the storage tank support leg system, piers, pile caps, pile foundations, to the ground, avoiding uneven settlement. Each foundation unit also includes an adjustable platform component, solving the problem of fixed elevations in traditional foundations once completed. This provides a precise leveling method for the subsequent installation of the storage tank support legs, ensuring the accuracy of equipment installation and avoiding equipment installation stress caused by foundation construction errors.

[0020] Example like Figure 1As shown, a foundation system for a concrete mixing plant storage tank includes multiple foundation units and multiple transverse connectors 3. The foundation units are connected into a whole by the transverse connectors 3. Each foundation unit includes: a vertical force transmission system, a storage tank support system, and an adjustable platform assembly. The vertical force transmission system includes a pile foundation 1 and a pile cap 2 set on the top of the pile foundation 1. The storage tank support system includes a support pier 4 set on the pile cap 2 and an embedded part 5 pre-embedded in the top of the support pier 4. The adjustable platform assembly is connected to the embedded part 5 and is used to adjust the distance between the platform assembly and the embedded part 5, thereby adjusting the installation elevation of the top of the adjustable platform assembly. The two ends of the transverse connectors 3 are respectively connected to the pile caps 2 of two adjacent foundation units so that the multiple foundation units form an integral load-bearing frame.

[0021] The vertical force transmission path from the embedded parts 5 and piers 4 of the storage tank support system to the pile cap 2 and pile foundation 1 of the vertical force transmission system to the ground ensures that the tank load can be safely and effectively transferred to the deep foundation, avoiding uneven settlement. Each unit corresponds to one support leg, decomposing the monolithic foundation into multiple independent foundation units, achieving precise design and construction. These units are then connected into a unified load-bearing frame via transverse connectors 3, greatly improving the overall stiffness, stability, and overturning resistance of the foundation system, effectively resisting horizontal and accidental loads.

[0022] In some embodiments, the transverse connector 3 is a detachable prefabricated component, the length of which is determined according to the actual design, and is used to connect adjacent pile caps 2. The detachable prefabricated component not only facilitates transportation, installation, and disassembly, improving the flexibility and convenience of construction, but also ensures the quality of the component through prefabrication, reduces on-site wet work, and significantly shortens the construction cycle.

[0023] The transverse connector 3 is made of either a steel beam or a prestressed concrete beam. Both ends of the transverse connector 3 are connected to the pile cap 2 in a load-transferable manner.

[0024] In some embodiments, the transverse connector 3 is a steel beam, and both ends of the transverse connector 3 are connected to the pile cap 2 by high-strength bolts or welding. The pile foundation 1 is a steel pipe pile, and the steel pipe pile is detachably connected to the pile cap 2 of the steel beam structure. The steel pipe pile can be quickly driven into the ground and connected to the pile cap 2 of the steel pile cap 2 by bolts or welding, realizing fully prefabricated construction, greatly shortening the construction period, and is particularly suitable for projects with tight schedules or soft soil foundations.

[0025] In some embodiments, the transverse connector 3 is a prestressed concrete beam, the pile foundation 1 is a prestressed concrete pipe pile, the steel bars at both ends of the transverse connector 3 extend into the adjacent pile cap 2, and the steel bar skeleton of the transverse connector 3 is connected to the steel bar skeleton of the pile cap 2 so that the transverse connector 3 and the pile cap 2 are integrally formed reinforced concrete structures. The pile cap 2, transverse connector 3 and pier 4 at the top of the pile foundation 1 are cast together to form an integral structure with greater structural rigidity, better integrity and durability. Moreover, the completely integrated structure can most effectively distribute and transfer the load between the foundation units and has the strongest ability to resist uneven settlement.

[0026] like Figure 2As shown, the embedded part 5 is an isosceles trapezoidal first trapezoidal block 41. The lower base of the first trapezoidal block 41 is embedded in the concrete of the support 4. Both trapezoidal surfaces of the first trapezoidal block 41 are equipped with first fixing plates with through holes. The adjustable platform assembly includes: a second trapezoidal block 51, a support 57, two first threaded rods 52, two trapezoidal push blocks 54 and a second threaded rod 55. The second trapezoidal block 51 has the same structure as the first trapezoidal block 41 and is symmetrically arranged above the first trapezoidal block 41. The fixing plate on the second trapezoidal block 51 is a second fixing plate. The inclined surfaces of the second trapezoidal block 51 and the first trapezoidal block 41 are arranged opposite each other. The support 57 is arranged on the lower base of the second trapezoidal block 51 and is used to connect the support legs of the storage tank. For example, bolt connection; two first threaded rods 52 are respectively set on both sides of the first trapezoidal block 41, and the two ends of each first threaded rod 52 pass through the through holes of the first fixing plate and the second fixing plate respectively, and each first threaded rod 52 is equipped with a locking nut 53 at the position of the first fixing plate and the second fixing plate. The locking nut 53 of the first trapezoidal block 41 is set on the top of the first fixing plate, and the locking nut 53 of the second trapezoidal block 51 is set below the second fixing plate; a trapezoidal push block 54 is respectively provided between the inclined surfaces of the first trapezoidal block 41 and the second trapezoidal block 51 on the same side, and the two inclined surfaces of each trapezoidal push block 54 are slidably connected to the inclined surfaces of the first trapezoidal block 41 and the second trapezoidal block 51 respectively. A through channel is opened along the thickness direction of each trapezoidal push block 54, and the two trapezoidal push blocks 54 move closer to the middle from both sides, and the two trapezoidal push blocks 54 are connected to the first trapezoidal block 41 through the inclined surfaces of the two trapezoidal push blocks 54. The cooperation of trapezoidal block 41 and second trapezoidal block 51 adjusts the height of the second trapezoidal block 51, thereby adjusting the installation elevation of the storage tank foundation system. The two ends of the second threaded rod 55 pass through the through channels of the two trapezoidal push blocks 54, with the ends of the second threaded rod 55 protruding from the through channels. Locking threaded sleeves 56 are provided on the exposed portions of the second threaded rod 55. After adjusting the installation elevation, the two locking nuts 53 are tightened, respectively abutting against the top of the first fixed plate and the bottom of the second fixed plate. The locking threaded sleeves 56 on the second threaded rod 55 are tightened, abutting against the lower surface of the corresponding trapezoidal push block 54. The two locking threaded sleeves 56 prevent the two trapezoidal push blocks 54 from moving away from each other, and the two sets of locking nuts 53 prevent the two trapezoidal push blocks 54 from getting close to each other, forming a double locking mechanism that ensures the stability and safety of the adjustment result under long-term vibration loads. Figure 2 In this embodiment, the trapezoidal push block 54 has two through channels and two corresponding second threaded rods 55, with locking threaded sleeves 56 at both ends of each second threaded rod 55.

[0027] It is worth noting that the number and layout of the basic units are matched with the number and position of the storage tank legs. This embodiment has four basic units, which are suitable for four-leg storage tanks.
