Description

Technical Field

[0001] The invention relates to the technical field of port engineering, and in particular to a bottom-supported temporary wharf structure with an anchor system and a construction method thereof. Background Art

[0002] The structural types of general temporary docks may include fixed docks and floating docks. Fixed docks may adopt gravity structures, high pile structures or sheet pile structures. The working principle of gravity structures is to rely on the deadweight of the structure to resist horizontal loads such as waves and maintain its own stability. It is generally composed of concrete and sand and gravel materials and is mostly suitable for shallow water conditions. The working principle of floating docks is generally composed of the dock body and the mooring system, which is suitable for slightly deeper water conditions. Fixed docks have a long construction and demolition cycle and are not reusable, which in turn increases construction costs, wastes sand and gravel materials, and is not environmentally friendly. Floating docks use anchor structures to maintain the stability of the dock. They rely too much on the mooring system. The anchor foundation that can be automatically installed and recovered generally has limited bearing capacity and cannot withstand relatively severe wave and current conditions. In addition, for situations where there is a need for shelter, the air-permeable characteristics of the floating body reduce the wave-blocking performance of the structure. Summary of the invention

[0003] In order to solve the above technical defects in the prior art, the purpose of the present invention is to provide a temporary dock structure with anchor system and its construction method, which uses a main structure that can be repeatedly filled and drained, and is supplemented by anchor system to fix the main structure, so as to form a temporary berthing facility. It has the characteristics of being able to be quickly formed and reused, improves the efficiency of water operations, saves costs, and is a green and environmentally friendly innovative structural type.

[0004] In order to solve the above technical problems, the solution adopted by the present invention is as follows:

[0005] The present invention provides a temporary dock structure with anchors, comprising a dock main structure, a water injection and drainage system, an anchor structure, a cable-twisting device and a ship mooring facility (a bed may not be provided), wherein the cable-twisting device is used for installing and recovering the anchor structure, and the dock main structure is a box-type structure with compartments, wherein the compartments are used for storing water and adjusting the draft of the main structure; the dock main structure also has an upright ship berthing surface and a horizontal dock working surface; the water injection and drainage system is arranged inside the dock main structure, and is used for completing the filling and drainage operations of the dock main body, controlling the draft of the dock main body, and realizing the conversion of the dock main body between a floating state and a bottom-sitting state; the anchor structure comprises a mooring cable and an anchor foundation, and a restoring force is provided to the dock main structure through the anchor structure, so as to improve the structural stability of the dock structure; the ship mooring facility comprises a mooring bollard and a rubber fender, which are used for ship berthing operations.

[0006] The main structure of the temporary wharf of the present invention is of the bottom-sitting type, not the floating type. Different from the conventional gravity-type wharf, its working principle does not completely rely on its own weight and the weight of the filler to meet the stability, but relies on its own weight, the weight of the ballast and the tension of the anchor structure to meet its stability under the action of waves and water flow. Therefore, the pressure on the foundation is small, there is no need to set up a base bed, the requirement for the bearing capacity of the foundation is also small, and the applicable conditions are wide.

[0007] The temporary wharf structure of the present invention can provide shelter conditions for ships berthed on the inner side, without the need to construct facilities such as breakwaters.

[0008] Preferably, the main structure of the dock is in various shapes such as rectangular, U-shaped, or U-shaped.

[0009] In any of the above solutions, it is preferred that the main structure of the wharf is made of reinforced concrete or steel structure or high-strength composite material.

[0010] In any of the above schemes, preferably, a ballast is provided in the main structure of the dock, and the ballast is water or stone or sand or concrete block or iron block. Of course, other materials can also be selected to enhance the stability of the dock body under the action of waves and water flow.

[0011] In any of the above schemes, it is preferred that the temporary wharf structure is formed by splicing multiple sections of the wharf main structure, and the number of spliced ​​sections is greater than or equal to 1; the length of each section is determined according to the construction capacity.

[0012] Another aspect of the present invention provides a construction method of a bottom-supported temporary wharf structure with an anchor system, comprising the following steps:

[0013] In the first step, after the temporary wharf structure is moved to the designated project location, the anchor foundation is thrown to the designated location;

[0014] The second step is that after the temporary wharf structure is accurately positioned, water is injected into the main body of the wharf through the injection and drainage system, and the main structure of the wharf sinks until it sits on the seabed or foundation bed;

[0015] The third step is to tighten the mooring ropes on both sides to achieve the operating state;

[0016] The fourth step is to recover the anchor foundation and mooring cables, and use the water injection and drainage system to pump water out of the dock structure and float it to a floating state, thus completing the dismantling of the dock structure.

[0017] The working principle of the temporary dock structure with anchor system of the present invention is as follows: the draft of the temporary dock structure can be adjusted through the injection and drainage system, so that the structure can be switched between floating and bottoming states; after the dock is bottomed, it enters the operating state. Under the action of horizontal loads such as ship loads and wave forces, the deadweight of the dock structure and the mooring cables can provide a restoring force in the opposite direction of the external load to resist the horizontal sliding and overturning of the dock structure, reduce the unevenness of the dock main structure on the foundation operation, and reduce the foundation stress. Under the operating conditions without shelter, the temporary dock structure can take into account both wave blocking and shelter functions.

[0018] In summary, the bottom-supported temporary dock structure with an anchor system of the present invention has the following advantages: it can be implemented quickly, improving construction efficiency; it has a temporary shielding function in the face of relatively severe sea conditions, which can increase the number of working days and reduce the difficulty of construction; it can be reused, saving the construction cost of the temporary dock and avoiding waste of materials; it reduces the utilization rate of natural materials such as sand and gravel, and is a green and environmentally friendly structural type.
