Hydraulic dredging construction method for hard clay in offshore wind power jacket foundation pile
The invention relates to the technical field of wind power installation, in particular to a hydraulic dredging construction method for hard clay in an offshore wind power jacket foundation pile, which comprises the steps of construction preparation, ship parking, ship positioning, mud pumping in the pile, mud surface elevation acceptance and ship moving and repositioning. Compared with a traditional method that a diver uses a mud pumping pipe to pump mud in a handheld mode, the offshore wind power mud surface elevation control method has the advantages that the using time of the diver is greatly shortened, and all-day continuous operation is achieved. And under the conditions of much sludge and large sludge pumping depth, the construction efficiency can be greatly improved by adopting the sludge pumping mode. Compared with a traditional crane ship, the cargo ship is provided with the crawler crane for operation, and ship machine rents can be reduced. And after mud pumping is completed, the diver carries out high point troubleshooting, the diver is guided to pump mud for the high point, and it is guaranteed that the height of the mud surface in the engineering pile is uniform.
本发明涉及风电安装技术领域，尤其涉及海上风电导管架基础桩内硬质黏土水力疏浚施工方法，包括施工准备、船舶驻位、船舶调位、桩内抽泥、泥面标高验收和移船再定位；本发明海上风电泥面标高控制方法与传统的潜水员用抽泥管手持抽泥，大大减少了潜水员的使用时间，实现了全天连续作业。对于一些淤泥多，抽泥深度厚的情况，采用本抽泥方式可以极大地促进了施工效率。使用货船配备履带吊作业，对比传统起重船，可以减少船机费租金。在抽泥完成后，潜水员进行高点排查，针对高点进行潜水员引导抽泥，保证了工程桩内的泥面高度均匀。
