Description

Technical Field

[0001] This utility model relates to the field of marine bridge construction technology, and in particular to a sunken marine mixing plant storage silo. Background Technology

[0002] Offshore mixing plants are essential large-scale temporary facilities in the construction of offshore bridges. Due to the complex conditions and high costs of offshore construction, the platform area of ​​offshore mixing plants can only meet basic functional requirements, leaving limited floor space for storage silos. The foundations of the storage silos are generally located on the offshore mixing plant platform. A full storage silo typically bears a vertical load of several thousand tons, placing high demands on the platform's pile top beams and Bailey bridges. This results in complex force transmission in the offshore mixing plant platform structure, reduced safety reserves, and increased steel consumption. Furthermore, to meet storage capacity requirements, the storage silos are relatively tall within the limited floor space. Under the influence of strong winds at sea, this leads to increased steel consumption for the storage silos and their foundations, posing significant structural safety risks in the face of extreme conditions such as typhoons. Therefore, the structural layout of the offshore mixing plant platform and storage silos urgently needs optimization while still meeting storage requirements. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a submerged offshore mixing plant storage silo.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a submerged offshore mixing plant storage silo, comprising a storage silo body, a belt conveyor system located at the discharge port at the bottom of the storage silo body, and several steel pipe piles installed at sea. Adjacent steel pipe piles are welded together with horizontal bracing. A storage silo foundation is welded to the top of the steel pipe piles. Support legs on the storage silo body are welded to the top of the storage silo foundation. Corbels corresponding to the belt conveyor system are welded to the top of the side wall of the steel pipe piles. The belt conveyor system is installed on the top of the corbels. A maintenance platform is installed on the top of the corbels. A wave-damping mechanism located below the belt conveyor system is installed on the side wall of the steel pipe piles. An elastic buffer mechanism connects the wave-damping mechanism and the steel pipe piles.

[0005] Specifically, the steel pipe piles are friction piles driven into the seabed. The planar layout dimensions of the steel pipe piles are consistent with the planar dimensions of the support legs, and the top elevation of the steel pipe piles is lower than the elevation of the mixing plant platform.

[0006] Specifically, the brackets are I-beams with a triangular structure, welded to the steel pipe piles, providing support for the belt conveyor system and maintenance platform, and transferring the load to the steel pipe piles.

[0007] Specifically, the horizontal joints are made of steel pipes, which are arranged longitudinally, transversely, and diagonally to connect the steel pipe piles into a whole.

[0008] Specifically, the foundation of the storage silo is a welded steel plate structure, and several stiffening plates are welded to the circumferential sidewalls to reinforce the top of the steel pipe piles and provide a supporting plane for the outriggers.

[0009] In particular, the storage silo body is an inverted four-sided pyramid structure welded from steel plates, supported by legs, and stores sand and gravel inside.

[0010] In particular, the maintenance platform is a steel profile and steel panel structure, supported on steel pipe piles by brackets, providing an operating platform for maintenance work on the storage silo body and belt conveyor system.

[0011] Specifically, the elastic buffer mechanism is a spring, and the wave-damping mechanism is a flat porous structure. It is connected to the steel pipe pile through the spring and is located at the bottom of the belt transmission system. Through the porous structure and overall elastic deformation, it absorbs wave energy and prevents waves from damaging the belt transmission system.

[0012] The beneficial effects of this utility model are:

[0013] Compared with traditional offshore mixing plant platforms, this utility model eliminates the pile top crossbeam, Bailey beam main beam and pad beam. The storage bin legs directly transfer the upper load to the steel pipe piles. The force transmission path is simple, clear and reliable, saving the amount of steel used in the platform and has good economic benefits.

[0014] This invention achieves a sunken storage silo by lowering the top elevation of the steel pipe piles, thereby reducing the overall height of the silo and giving it stronger wind resistance, making it safer in extreme conditions such as typhoons at sea.

[0015] This invention protects the lower belt conveyor system from damage by adding a wave-proof mechanism. Attached Figure Description

[0019] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-2As shown, a submerged offshore mixing plant storage silo includes a storage silo body 6, a belt conveyor system 7 located at the discharge port at the bottom of the storage silo body 6, and several steel pipe piles 1 set at sea to bear the vertical and horizontal loads of the storage silo body 6. A horizontal bracing 2 is welded between adjacent steel pipe piles 1 to increase the overall stability of the steel pipe piles 1. A storage silo foundation 4 is welded to the top of the steel pipe piles 1 to reinforce the top of the steel pipe piles 1 and evenly distribute the load of the support legs 5. The support legs 5 on the storage silo body 6 are welded to the top of the storage silo foundation 4. The support legs 5 transfer the weight of the storage silo itself and the weight of the sand and gravel in the storage silo to the storage silo foundation 4. The storage silo body 6 stores sand and gravel for mixing concrete.

[0022] Specifically, steel pipe pile 1 is a friction pile driven into the seabed. The planar layout dimensions of steel pipe pile 1 are consistent with the planar dimensions of support leg 5. The top elevation of steel pipe pile 1 is lower than the elevation of the mixing plant platform. The horizontal connector 2 is a steel pipe, which is arranged longitudinally, transversely and diagonally to connect steel pipe pile 1 into a whole. The storage silo foundation 4 is a welded steel plate structure, and several stiffening plates are welded to the circumferential sidewalls to reinforce the top of steel pipe pile 1 and provide a support plane for support leg 5. The storage silo body 6 is an inverted four-sided pyramid structure welded from steel plates, supported by support leg 5, and stores sand and gravel inside.

[0023] A bracket 3 corresponding to the belt conveyor system 7 is welded to the top of the side wall of the steel pipe pile 1. The belt conveyor system 7 is installed on the top of the bracket 3 and is used to horizontally transport sand and gravel to the mixing machine. A maintenance platform 8 is installed on the top of the bracket 3. A wave-proof mechanism 9 located below the belt conveyor system 7 is installed on the side wall of the steel pipe pile 1 to protect the belt conveyor system 7 from wave erosion and damage. An elastic buffer mechanism 10 is connected between the wave-proof mechanism 9 and the steel pipe pile 1.

[0024] Specifically, the bracket 3 is an I-beam with a triangular structure, welded to the steel pipe pile 1, providing support for the belt conveyor system 7 and the maintenance platform 8, and transferring the load to the steel pipe pile 1. The maintenance platform 8 is a steel profile and steel panel structure, supported on the steel pipe pile 1 by the bracket 3, providing an operating platform for maintenance work on the storage silo body 6 and the belt conveyor system 7. The elastic buffer mechanism 10 is a spring, and the wave-proof mechanism 9 is a flat, porous structure connected to the steel pipe pile 1 via the spring. Located at the bottom of the belt conveyor system 7, it absorbs wave energy through its porous structure and overall elastic deformation, preventing wave impact from damaging the belt conveyor system 7.

[0025] The construction of this utility model includes the following implementation steps:

[0026] Step 1: Integrate the design of steel pipe pile 1 with the storage silo structure. The planar dimensions of the steel pipe pile 1 and the support legs 5 of the storage silo body 6 are consistent. Determine the planar position, pile length and pile top elevation of the steel pipe pile 1, and determine the structural dimensions of the storage silo.

[0027] Step 2: Drive steel pipe piles 1 using a pile driving vessel or floating crane, and install brackets 3 and flat joints 2.

[0028] Step 3: Install the wave-proof mechanism 9 and the belt conveyor system 7.

[0029] Step 4: Weld the foundation of the storage silo.

[0030] Step 5: Process the storage silo body 6 and support legs 5 in one piece, hoist the storage silo body 6, and weld the support legs 5.

[0031] Compared to traditional offshore mixing plant platforms, this invention eliminates the need for pile top beams, Bailey bridge main beams, and pad beams. The support legs 5 of the storage silo directly transfer the upper load to the steel pipe piles 1, resulting in a simple, clear, and reliable force transmission path. This saves on platform steel consumption and offers excellent economic benefits. By lowering the elevation of the top of the steel pipe piles 1, a sunken storage silo is achieved, reducing the overall height of the silo and giving it stronger wind resistance, making it safer in extreme offshore typhoon conditions. The addition of a wave-resistant mechanism 9 protects the lower belt conveyor system 7 from wave damage.
