Steel sheet pile cofferdam structure and construction method thereof
The invention provides a steel sheet pile cofferdam structure and a construction method thereof, the steel sheet pile cofferdam structure comprises a rectangular steel sheet pile defined by main piers, a plurality of enclosing purlins are arranged on the inner side of the steel sheet pile from top to bottom, the enclosing purlins are a first enclosing purlin, a second enclosing purlin and a third enclosing purlin in sequence, and the first enclosing purlin, the second enclosing purlin and the third enclosing purlin are composed of a plurality of middle supports and inclined supports. The construction method comprises the following steps that in steel sheet pile cofferdam drilling trepanning construction, 360-type rotary drilling is adopted for hole forming, the diameter of a drill hole is 0.8 m, the arrangement distance of trepanning holes is 0.6 m, and the depth is controlled by 3.35 m of a steel sheet pile embedded into a bearing platform bottom strong weathering slate; the cofferdam structure composed of the steel sheet piles, the three layers of surrounding purlins, the corner supports, the middle supports and the inclined supports is adopted, the cofferdam structure is assembled and welded into the whole supporting system, and the cofferdam structure is simple in structure, convenient to install, easy to construct, low in cost, safe and reliable.
本发明提出一种钢板桩围堰结构及其施工方法，包括主墩围城的矩形状的钢板桩，所述钢板桩的内侧从上到下设有多个围檩，依次为第一围檩、第二围檩与第三围檩，所述为第一围檩、第二围檩与第三围檩是由多个中支撑与斜支撑组成。施工方法，包括以下步骤：钢板桩围堰钻孔套眼施工采用360型旋挖钻成孔，钻孔直径0.8m，眼孔布置间距@0.6m，深度以钢板桩嵌入承台底强风化板岩3.35m控制；埋设钢护筒、钻进泥浆护壁、清孔等按常规法施工等步骤，本发明采用钢板桩、三层围檩以及角支撑、中支撑与斜支撑组成的围堰结构，拼装焊接成整体支护体系，结构简单，安装方便，易于施工，费用低，安全可靠。
