Construction method for bare rock pile foundation in unshielded water area
The invention discloses a construction method of a bare rock pile foundation in an unshielded water area. The construction method comprises the following steps: S1, backfilling an artificial foundation bed; s2, erecting a steel platform; s3, the steel platform is subjected to pile planting reinforcement; s4, subsection vibration sinking is conducted on the cast-in-place pile steel casing; s5, impact hole forming; s6, hole cleaning and concrete pouring; s7, the steel platform is dismantled; and S8, foundation bed treatment. According to the construction method, the problem that the steel pipe pile is difficult to stabilize under the condition that no covering layer exists is solved, the backfill work amount is reduced through local pile planting, the problems of stone layer penetrating and the like are effectively solved by using the impact grabber to be matched with the steel pile casing segmented vibration sinking process, the process feasibility is achieved, and the construction difficulty is reduced.
一种无掩护水域裸岩桩基施工方法，其步骤为：S1.人工基床回填；S2.钢平台搭设；S3.钢平台植桩加固；S4.灌注桩钢护筒分段振沉；S5.冲击成孔；S6.清孔、混凝土浇筑；S7.拆除钢平台；S8.基床处理。本发明的施工方法解决了无覆盖层情况下钢管桩稳桩困难等问题，利用局部植桩降低了回填工程量，使用冲击抓配合钢护筒分段振沉工艺，有效解决了穿石层等问题，实现了工艺可行性，降低了施工难度。
