Abstract

The invention discloses a construction process for a single-pile wind turbine foundation in an intertidal zone, which comprises the following steps of: hauling a locating ship, a transporting ship and a craning ship to an appointed place during high tide; anchoring and locating the craning ship; horizontally hoisting a foundation pile; staking the foundation pile; loading the foundation pile into a pile clamping device; adjusting the verticality of the foundation pile; naturally sinking the foundation pile; examining the verticality, wherein if the verticality does not meet the requirements, the natural sinking of the foundation pile is carried out again; releasing a hoisting point; hoisting a pile hammer and a pressure hammer; starting a hydraulic impact hammer power system; hammering with an impact hammer; examining the verticality, wherein if the verticality does not meet the requirements, the hammering of the impact hammer is adjusted; sinking the pile by impact; measuring an elevation and a penetration degree, wherein if the elevation and the penetration degree do not meet the requirements, the step of sinking the pile by impact is adjusted; stopping the hammer; and demounting the craning ship. The invention has the following advantages of solving the problems of short effective operation time and low construction work efficiency for the wind turbine foundation construction in the intertidal zone, and greatly reducing construction cost.

Description

technical field [0001] The invention relates to a construction technology of a wind turbine foundation, in particular to a construction technology of a single-pile wind turbine foundation in an intertidal zone. Background technique [0002] The intertidal zone is the area between the high and low tide levels of the spring tide, which is submerged and exposed as the tide rises and falls. According to preliminary estimates, the annual average wind speed in the intertidal zone can reach 67 m / s, so there is available wind energy in the intertidal zone. For intertidal wind power projects, it mainly involves the construction of the foundation of the wind turbine and how to install the wind turbine. [0003] For the wind turbine foundation construction process, there are currently two processes. One is the single pile fan foundation construction technology, and the other is the pile foundation construction technology. For the single-pile wind turbine foundation construction tech...
