Description

Technical Field

[0001] The invention relates to a large-tonnage fast-arranged mooring pile for ship typhoon protection and an installation method thereof. Background Art

[0002] At present, since ships may experience typhoons when moored at docks in summer, typhoon-proof mooring is required. On the one hand, the generation and movement path of typhoons are sudden, and there is uncertainty in the forecast. When typhoon-proof emergency response is required, the time is short. If mooring equipment is purchased, the time is often insufficient. In addition, the back of the mooring equipment needs to be reinforced, and there is insufficient time to set up scaffolding, prepare materials, and prefabricate and install. On the other hand, the wind speed of typhoons is very high and has great destructive power. The tonnage required for mooring equipment is very large, often reaching 100 tons or more. There are two types of existing mooring piles. One is a double-barrel mooring pile with a base, which needs to be ordered and purchased, and the procurement cycle is long. On the other hand, the base is arranged on the deck surface, and the back cannot be aligned with the structure, so the back needs to be strengthened, and the installation time is long, which does not meet the requirements. The other is a single-barrel mooring pile, which is easy to arrange and can be arranged at the main structure to ensure alignment, but the tonnage of the single-barrel mooring pile within the standard is small and cannot be used. Summary of the invention

[0003] The purpose of the present invention is to provide a large-tonnage fast-arrangement mooring pile for ship typhoon prevention that can meet the 100-ton mooring force for typhoon prevention, can be quickly arranged, and can avoid the design of reverse reinforcement.

[0007] Another technical solution adopted by the present invention to achieve the above-mentioned purpose is: a method for quickly arranging large-tonnage mooring piles for ship typhoon prevention, comprising the following steps: a. Determine the number and tonnage of mooring piles to be arranged according to the typhoon mooring arrangement diagram and typhoon mooring calculation; b. Avoid reverse reinforcement according to the requirements of rapid layout, determine the structure of the mooring pile as a single-tube mooring pile, perform strength calculation according to mooring requirements, and determine the plate thickness and material of each component; c. Design welding nodes. For large-tonnage fast-arrangement pile columns (1) and pile pads (2), full penetration welding is adopted to ensure effective transmission of mooring force. For the pile pads (2) and the main deck (10) of the ship, fillet welds, butt welds and plug welding holes are used to effectively connect and complete the installation.

DETAILED DESCRIPTION

[0016] like Figures 1 to 4As shown, a large-tonnage fast-arranged cable pile for ship typhoon prevention comprises a large-tonnage fast-arranged cable pile column 1, a cable pile pad 2, a cable pile top plate 3 and a cable limit plate 4. The large-tonnage fast-arranged cable pile column 1 is fixedly connected to the cable pile pad 2 through a cable pile column full-penetration joint 7 and a cable pile column welded joint back plate 8. The cable pile pad 2 is fixedly connected to the ship's main deck 10 through a pad annular fillet weld 5, a pad butt weld 6 and a pad-to-deck connection plug welding hole 9. The cable pile top plate 3 is installed on the top of the large-tonnage fast-arranged cable pile column 1. The cable limit plates 4 are respectively installed on the large-tonnage fast-arranged cable pile column 1. The large-tonnage fast-arranged cable pile column 1, the cable pile top plate 3 and The cable limit plate 4 is welded to form a large-tonnage rapid deployment cable pile body for typhoon prevention, which bears the cable load (100 tons) of the typhoon prevention mooring. The use requirement of the mooring cable is to lead out the rope from the lower part of the large-tonnage rapid deployment cable pile column, which avoids excessive bending moment and mainly bears shear force. The strength of the large-tonnage rapid deployment cable pile needs to be checked according to ISO standards and meet the requirements. The cable pile column full-penetration joint 7 and the cable pile column full-penetration joint back plate 8 are the connection nodes of the large-tonnage rapid deployment cable pile pad 2. The mooring force is transmitted to the cable pile pad 2 by full-penetration. In order to facilitate welding, the cable pile column full-penetration joint back plate 8 is used as a welding pad, and the weld strength is strong. The degree needs to be calculated in accordance with the requirements of welding specifications to meet the strength requirements. The welds of the welding heads need to be quality controlled and X-ray flaw detection is required to ensure the quality of welding. Welding defects need to be repaired, and the repair process needs to meet the welding process assessment requirements. The cable pile pad 2 is arranged on the main deck 10 of the ship. The main structure of the ship, such as the transverse frame, longitudinal girder, transverse or longitudinal bulkhead, has a relatively strong bearing capacity and can withstand the large tonnage mooring force of typhoon-proof mooring. The cable pile pad 2 uses the pad annular fillet weld 5, the pad butt weld 6, and the pad and deck connection plug welding hole 9 to effectively connect with the main deck 10 of the ship to transfer the mooring force to the main deck and the main structure. At the place, all welding needs to be calculated for welding strength to ensure welding strength and reserve sufficient strength margin. Welding needs to be inspected to ensure welding quality, avoiding reverse reinforcement. A method for quickly arranging large-tonnage piles for ship typhoon prevention, comprising the following steps: a. According to the typhoon prevention mooring layout diagram and typhoon prevention mooring calculation, determine the number and tonnage of piles to be arranged, the tonnage is generally controlled at about 100 tons, and it is recommended to change the arrangement of piles with too large tonnage, add new piles, and recalculate; b. According to the requirements of rapid arrangement to avoid reverse reinforcement, determine the pile structure as a single-barrel pile, perform strength calculation according to mooring requirements, and determine the plate thickness and material of each component;c. Design welding nodes. For large-tonnage rapid arrangement of cable pile columns 1 and cable pile pads 2, full penetration design is adopted. Cable pile column full penetration joints 7 and cable pile column penetration joint back plates 8 are used for fixed connection to ensure effective transmission of mooring force. For cable pile pads 2 and the main deck 10 of the ship, pad annular fillet welds 5, pad butt welds 6 and pad and deck connection plug welding holes 9 are used for fixed connection to complete the installation. Finally, all information of the entire cable pile is established, and a reasonable layout is made for easy operation. ;
