Description

Yacht wharf structure under ultra-large water head

Technical Field

The utility model relates to the technical field of water transport engineering, in particular to a yacht wharf structure under ultra-large water head.

Background

The yacht industry has gained increased attention and interest as an emerging and sunny industry, which involves waters including coastal, lake-and river-based waters. The large water level difference area mainly considers areas with water level differences exceeding 10m, such as mountain lakes, reservoirs, mountain rivers and the like, and the requirements on yacht wharfs are quite different because of different natural environments of water areas and different yacht berthing requirements from common passenger and cargo ships. The water level of the mountain lake and the reservoir is higher in the flood storage area, the water level is lower in the flood discharge period and the water level of the mountain lake and the reservoir is generally steep, and the position of the water level is basically unchanged when the water level changes; the mountain river is different, the section is similar to V shape, the river surface is wider when the water level is high, and the river surface is very narrow when the water level is low. The water surface of the shoreline moves a large distance, so that the position of the wharf must be moved correspondingly.

The dock features in large water level difference are generally open, and the ship and the dock are inevitably influenced by external wind, wave, current and the like, so that the mooring requirements of the yacht and the dock are met in a high water level state, the pile is stressed greatly, the pile diameter and the pile length are inevitably increased, the cost is high, and the pontoon dock and the frame type high pile dock which adopt pile guiding positioning are all large in pile foundation quantity and have huge investment. Therefore, pontoons are increasingly used as yacht wharfs, and are usually composed of pontoons, anchor systems of pontoons, supporting facilities and access bridges. The pontoon needs to rise and fall along with the water level, and the anchor system of the pontoon depends on the anchor chain, the stay bar and the approach bridge which are connected with the pontoon, and is adjusted according to different water level differences. Considering the condition limitations of inconvenient operation of tourists and mobile machinery on an approach bridge, the conventional wharf pontoon type pontoon is suitable for the condition of small water level amplitude and is not suitable for the use in areas with large water level difference.
