Abstract
The invention relates to an installation system and construction method of a wind turbine assembly in a sea intertidal zone. The installation system comprises an operation platform and a crawling crane, wherein the operation platform can float, move and be docked on the sea and can also be set on a muddy surface of a beach to carry out construction operation. The construction method includes the steps that when a tide rises, the operation platform is moved and docked through a tug, and a pile transporting boat is docked; when the tide falls, the operation platform is set on the beach, and steel pipe piles are craned by the crawling crane to sink; when the tide rises, the operation platform is moved and docked, and the pile transporting boat carries wind turbine equipment and then is berthed; when the tide falls, the operation platform is set on the beach, and the whole wind turbine assembly is craned by the crawling crane to be installed. The installation system and construction method of the wind turbine assembly in the sea intertidal zone have the advantages that the operation platform does not need to be leveled by adding ballast water when in a floating state, and the depth of immersion is smaller than 1.6m; the operation platform can be set on the muddy surface of the beach to carry out construction, and the 1000t crawling crane is carried by the operation platform and can move on the operation platform and be used for large-diameter steel pipe pile sinking operation and wind turbine separate installation; the problem that large ships can not run into a shallow intertidal zone to carry out construction is solved.
Description
Technical field
The invention belongs to offshore construction method, relate in particular to blower fan assembly installation system and the construction method thereof in region, a kind of marine intertidal zone.
Background technology
Under the combineds action such as high wind load, alluvion load, stream load, marine corrosion, it is large more than the technical risk of land that marine wind electric field fan is built, complex structure, and cost is high.
At present offshore wind turbine foundation type mainly contains: gravity type foundation, single pile type foundation, tripod type basis, jacket-type are basic, buoyant foundation.Wherein single pile type foundation has and manufactures simply, and without arranging sea bed, to landform strong adaptability, the advantage such as construct quick is most widely used in blower foundation.The type basis adopts the large diameter steel pipe pile of diameter 3～5m, after pile sinking, on stake top, fixes transition phase, blower fan pylon can be installed on it.But the type foundation construction needs large-scale sinking apparatus, as large-scale crane ship etc., its drinking water is generally larger, conventionally more than 2.5m.Simultaneously Fan Equipment size is generally larger, the high about 100m of blower fan tower barrel, and fan blade length is generally in 40～50m left and right, so the transportation of Fan Equipment, installs and also need large ship.Current at sea intertidal zone or offshore region of wind energy turbine set operated by rotary motion, the depth of water is more shallow, the large ship constructional difficulties of marching into the arena.And when the depth of water is less than 2m, the construction of cannot marching into the arena of existing traditional construction ship, has limited applying of offshore wind turbine greatly.
