Steel cofferdam construction method capable of guaranteeing steel cofferdam construction safety coefficient and post-construction accuracy
The invention discloses a steel cofferdam construction method capable of ensuring the construction safety coefficient and post-construction accuracy of a steel cofferdam, which comprises the following steps of: determining and calculating the position of a measuring point used by a first pile and related parameters by combining the field condition before formal pile sinking of the cofferdam, adopting any angle intersection control positioning in construction, and ensuring that the intersection angle is between 60 and 120 degrees; the distance between the control points is not suitable to be larger than 150 m, the known coordinates of the measurement control points and the pile position coordinates are used for calculating the included angle and the distance between the two measurement control points and the pile position, the steel cofferdam is combined through the steel pipe piles and the steel sheet piles, the number of supporting layers in the cofferdam is small, and the construction progress is fast. Compared with a steel pipe pile cofferdam, the steel sheet piles are used for replacing half of steel pipe piles, the construction progress is accelerated, and the cost of labor, machinery, material renting and the like can be greatly saved.
本发明公开了一种可以保证钢围堰施工安全系数和工后精确度的钢围堰施工方法，包括围堰，在正式沉桩前应结合现场情况确定并计算首桩所用的测点位置和有关参数，施工采用任意角交会控制定位，其交会角宜在60°～120°之间，且控制点间距不宜大于150m，利用已知的测量控制点坐标和桩位坐标，分别计算两个测量控制点与桩位之间的夹角和距离，通过钢管桩和钢板桩组合钢围堰，围堰内支撑层数较少，施工进度快。为承台施工节约了时间，可缩短施工工期，相比较钢管桩围堰，使用钢板桩代替一半钢管桩，提高了施工进度，可大幅度节约人工、机械、材料租赁等成本费用。
