Pile sinking construction method for quicksand stratum pile foundation of onshore wind power plant
A pile sinking construction method for a quicksand stratum pile foundation of an onshore wind power plant comprises the steps that grouting pipes are buried on the periphery of a pipe pile, and grouting is conducted on a quicksand layer through the grouting pipes, so that solidified cement and the quicksand layer form a whole, the effect of solidifying the quicksand layer is achieved, the friction force between the pipe pile and soil is enhanced, the pile body deviation phenomenon after the foundation pile is formed on the quicksand layer is avoided, and the service life of the foundation pile is prolonged. And the possible pile body fracture phenomenon under the lateral thrust of the quicksand layer is avoided, the foundation bearing capacity requirement of the foundation pile is met, and therefore the pile foundation construction problem of the quicksand layer is effectively solved.
一种陆上风电场流砂地层桩基础沉桩施工方法，在管桩周边埋设注浆管，通过注浆管向流砂层注浆，使凝固后的水泥与流砂层成为整体，起到固化流砂层的作用，从而增强管桩与土质的摩擦力，解决基础桩在流砂层成桩后的桩体偏位现象，以及在流砂层侧向推力的作用下可能出现的桩身断裂现象，满足基础桩的基承载力要求，由此有效解决了流砂层的桩基施工问题。
