Underwater covering-layer-free riverbed steel pipe pile guide hole construction method
The invention mainly relates to the field of overwater steel trestles, in particular to an underwater covering-layer-free riverbed steel pipe pile guide hole construction method. The method comprises the eight steps of S1, moving a weighing ship in place, S2, installing a temporary bailey beam and a bridge deck slab, S3, measuring and setting out and installing a guide frame, S4, lowering a steel casing, S5, drilling a drilling machine in place and guiding a hole, S6, planting a steel pipe pile and pouring concrete, S7, pulling out the steel casing and S8, dismantling the temporary bailey beam. A weighing ship and a completed steel pipe pile cross beam are used as a bearing main body to bear the construction load of the drilling machine hole guiding operation, and a novel steel pipe pile hole guiding method is formed. A traditional fishing method overhanging construction and overwater operation platform pile replacing construction are replaced, safety is higher, a large working face can be provided, and the construction efficiency is effectively improved. The problem that hole guiding of the steel pipe piles is difficult due to the fact that the foundation pit riverbed has no covering layer after the underwater low pile cap cofferdam is blasted or the slope of the foundation pit is diagonally rocked after the underwater low pile cap cofferdam is blasted is solved.
本发明主要涉及水上钢栈桥领域，具体的说是一种水下无覆盖层河床钢管桩引孔施工方法。本方法包括，S1.移称重船就位，S2.安装临时贝雷梁和桥面板，S3.测量放样安装导向架，S4.下放钢护筒，S5.钻机就位引孔，S6.栽入钢管桩、灌注混凝土，S7.钢护筒拔出和S8.拆除临时贝雷梁，共八个步骤。利用称重船舶和已完成的钢管桩横梁作为承重主体，承担其钻机引孔作业的施工荷载，形成新型的的钢管桩引孔方法。代替传统“钓鱼法”悬挑施工及水上作业平台“替桩”施工，更安全且可提供大幅工作面，有效提高施工效率。解决了因水下低桩承台围堰爆破后基坑河床无覆盖层或爆破后基坑边坡斜岩，导致钢管桩引孔困难的难题。
