Grouting construction method for offshore wind power II-type socketed pile foundation
The invention discloses a grouting construction method for an offshore wind power II-type socketed pile foundation. The grouting construction method comprises the following steps that S100, a steel pipe pile is sunk to the surface of a rock stratum; s200, a rock-socketed drilling machine is placed in the steel pipe pile for drilling; s300, the steel pipe pile is driven again to follow up to the pile bottom; s400, a rock-socketed drilling machine is placed in the steel pipe pile to conduct reaming and drill to the designed bottom elevation; s500, grouting is conducted on the area, between the steel pipe pile and the rock wall, of the reaming section; and S600, before grouting and initial setting, the steel pipe pile is subjected to secondary pile sinking to the designed elevation. The grouting construction system has the advantages that the construction process is convenient and fast, the grouting construction efficiency is high, the grouting construction system for the offshore wind power II-type socketed pile foundation is formed, and powerful guarantee is provided for ensuring the construction quality of socketed piles. The method can be used in offshore wind power socketed pile foundation grouting construction, and has popularization and application values.
本申请公开了一种海上风电Ⅱ型嵌岩桩基础灌浆施工方法，包括如下步骤：S100、将钢管桩沉桩至岩层表面；S200、在钢管桩内下放嵌岩钻机钻孔；S300、复打钢管桩跟进至桩底；S400、再在钢管桩内下放嵌岩钻机进行扩孔并钻至设计底标高；S500、对扩孔段的钢管桩与岩壁之间的区域进行灌浆；S600、在灌浆初凝前，对钢管桩进行二次沉桩至设计标高。本申请灌浆施工系统具有施工工艺便捷，灌浆施工效率高，形成了海上风电Ⅱ型嵌岩桩基础灌浆施工系统，为确保嵌岩桩的施工质量提供了有力保障。本申请可以在海上风电嵌岩桩基础灌浆施工中使用，具有推广和应用价值。
