Offshore wind power rock-socketed single pile construction optimization method
The invention provides an offshore wind power rock-socketed single pile construction optimization method which comprises the following steps: S100, mounting a tubular pile, and hammering and sinking the tubular pile; s200, when the soil layer is compact and hammering pile sinking is difficult, after in-pile hole cleaning is conducted on the pipe pile, the pipe pile is sunk to the designed elevation; s300, a plurality of rotary spraying pipes are sequentially arranged in the soil body around the pipe pile at intervals, and rotary spraying operation is carried out to form a pile periphery reinforcing layer; s400, underwater concrete is sprayed on the surface of the seabed through the rotary spraying pipe to form an anti-scouring layer; and S500, the tubular pile is backfilled with underwater concrete so as to recover the internal friction resistance in the tubular pile. According to the offshore wind power rock-socketed single pile construction optimization method, the bearing capacity of a foundation is effectively improved, and the time-consuming and labor-consuming process of rock socketed by medium-weathered hard rock is avoided, so that the construction cost is greatly reduced, and the construction period is greatly shortened.
本发明提供一种海上风电嵌岩单桩施工优化方法，包括：S100、安装管桩，并对所述管桩进行锤击沉桩；S200、当土层较为致密，锤击沉桩困难时，对所述管桩进行桩内清孔后，将所述管桩沉桩至设计标高；S300、在所述管桩周围土体内依次间隔设置多个旋喷管，并进行旋喷作业以形成桩外周加固层；S400、通过所述旋喷管在海床表面喷射水下混凝土以形成防冲刷层；S500、向所述管桩内回填水下混凝土以恢复所述管桩内的内摩阻力。本发明的海上风电嵌岩单桩施工优化方法有效提高了地基的承载能力，避免了费时费力的中风化硬岩嵌岩工序，从而大幅降低了工程造价，节省了大量的建设工期。
