Construction method of steel sheet pile cofferdam of water area no-covering-layer low pile cap
The invention discloses a construction method of a steel sheet pile cofferdam of a water area no-covering-layer low pile cap. The method comprises the following steps that the part, at the design position of the steel sheet pile cofferdam, of a riverbed surface is cleaned; according to the design position, a guiding device is arranged at the corresponding position on a water surface, and the guiding device is welded to brackets of steel pipe piles; groove milling does not need to be conducted on the part, at the design position, of a rock stratum, the steel sheet piles are inserted and driveninto the design position in the outer wall direction of the guiding device, and the steel sheet piles are sequentially connected end to end to form the steel sheet pile cofferdam; a bottom-layer innersupport is lowered into the steel sheet pile cofferdam, and the bottom layer inner support and the steel sheet pile cofferdam are welded and fixed through pulling rods; a middle-layer inner support and a top-layer inner support are sequentially lowered into the steel sheet pile cofferdam and fixed; and high-pressure grouting is conducted on the part, in the steel sheet pile cofferdam, of the rockstratum through a grouting device, so that the part, in the steel sheet pile cofferdam, of the rock stratum is impermeable. According to the method, the characteristics of self-strength and stabilityof the rock stratum are fully utilized, so that the design length of the steel sheet piles is effectively reduced.
本发明公开了一种水域无覆盖层低桩承台的钢板桩围堰的施工方法，其包括以下步骤：对钢板桩围堰的设计位置的河床面进行清理；根据设计位置，在水面上相应位置处设置导向装置，并将导向装置焊接于钢管桩的托架上；不需要对设计位置处的岩层进行铣槽，将钢板桩沿导向装置的外壁方向插打至设计位置，且依次首尾相连并形成钢板桩围堰；将底层内支撑下放到钢板桩围堰内，并与钢板桩围堰之间通过拉杆进行焊接固定；依次将中层内支撑和顶层内支撑下放到钢板桩围堰内并固定；采用注浆设备对钢板桩围堰内的岩层进行高压注浆，以使钢板桩围堰内的岩层不透水。本发明充分的利用岩层自身强度和稳定性的特点，有效的减少了钢板桩的设计长度。
