Construction method of large-diameter single-pile stabilizing platform
The invention discloses a construction method of a large-diameter single-pile stabilizing platform. The method comprises the following steps that 1, the pile stabilizing platform is hoisted and positioned, and a crane ship hoists the pile stabilizing platform to a predetermined construction machine position coordinate; 2, the pile stabilizing platform is fixed and adjusted, the center coordinate of the pile stabilizing platform and the construction machine position coordinate are adjusted to be within the allowable deviation range, the pile stabilizing platform is sunk and fixed, the levelness of the pile stabilizing platform is adjusted, and the pile stabilizing platform is welded and fixed; 3, a single pile body is hoisted and sunk, the single pile body is hoisted into the pile stabilizing platform, the perpendicularity of the single pile body is adjusted to be vertical through the pile stabilizing platform, and the single pile body is sunk into a seabed; and 4, the pile stabilizing platform is dismounted and hoisted, and auxiliary piles around the pile stabilizing platform are fixedly dismounted and integrally hoisted. The perpendicularity precision of the single pile body is strictly controlled in the whole construction process, vertical pile sinking is guaranteed, the construction quality is qualified, the construction difficulty is lowered, and the project progress can be accelerated.
本发明公开一种大直径单桩稳桩平台的施工方法，所述方法包括以下步骤：步骤一：稳桩平台的吊装及定位，起重船将稳桩平台吊至预先确定的施工机位坐标处；步骤二：稳桩平台的固定及调整，调整稳桩平台中心坐标和施工机位坐标在允许的偏差范围内，将稳桩平台下沉固定，调整稳桩平台水平度，对稳桩平台进行焊接固定；步骤三：单桩体的吊装和沉桩，将单桩体吊至稳桩平台中，稳桩平台对单桩体垂直度调节竖直，将单桩体沉桩入海床上；步骤四：稳桩平台拆除和起吊，将稳桩平台四周的辅助桩固定拆除并整体吊起。整个施工过程严格控制单桩体垂直精度，保证垂直沉桩，确保施工质量合格，并且施工难度得以降低有利于加快工程进展。
