Construction method of wind power foundation secant pile
The invention relates to a construction method of a wind power foundation secant pile, which comprises the following steps of: setting out by a GPS (Global Positioning System), calculating the coordinate of each pile position, accurately setting out the positions of two A piles by taking the pile center as an intersection point, and determining the position of a B pile according to the positions of the two A piles; the first-sequence piles and the second-sequence piles are constructed in a jumping pile mode through the all-casing pile foundation, concrete is poured after construction is completed, and the first-sequence piles and the second-sequence piles are fused into a whole to be in an embedded and meshed state. The common use method of the secant pile is introduced into wind power foundation treatment, the advantages of the secant pile are utilized, the super stability and super static load capacity of the cylinder are also utilized, the construction period is shortened, the occupied area is reduced, concrete is reduced, and the construction method is worthy of application and popularization.
本发明涉及一种风电地基咬合桩的施工方法，通过GPS放样和计算各桩位的坐标，以桩中心为交点，将两个A桩的位置精确放出，通过两个A桩的位置，定出B桩的位置；通过全套管桩基采用跳桩施工第一序桩和第二序桩，完成后浇筑混泥土，使第一序桩和第二序桩融合一体呈嵌入咬合状态。将咬合桩的普通用法引入风电地基处理中，既利用了咬合桩的优势，又利用了筒形超稳定性和超静载能力，缩短了施工工期减少了占地面积，减少了混凝土，该工法值得推广运用。
