Sea area bare rock large-diameter rotary excavating pile outer pile casing and inner pile casing rock-socketed embedding construction method
The invention relates to the technical field of rotary excavating piles, and discloses a sea area bare rock large-diameter rotary excavating pile outer pile casing and inner pile casing rock-socketed embedding construction method which comprises the steps that (1) an outer pile casing is put into seawater, the bottom of the outer pile casing abuts against the top of bare rock, and an outer casing space is defined by the outer pile casing; (2) a cone barrel drill is adopted for downwards annularly cutting the bare rock, an annular groove is formed in the bare rock, a rock pillar is formed in the bare rock, and the annular groove surrounds the periphery of the rock pillar; (3) an inner pile casing is put into the outer cylinder space, the lower portion of the inner pile casing is embedded into the annular groove to form a lower section, and a lower annular cavity is formed between the outer side wall of the lower section and the inner side wall of the annular groove; the upper portion of the inner protective cylinder is exposed in the outer cylinder space to form an upper section, and an upper annular cavity is formed between the outer side wall of the upper section and the inner side wall of the outer protective cylinder. And (4) the outer pile casing is pulled out. And the problem of burying the large-diameter rotary excavating pile casing of the bare rock in the sea area is solved.
本发明涉及旋挖桩的技术领域，公开了海域裸岩大直径旋挖桩外护筒及内护筒嵌岩埋设施工方法，1)、在海水中下入外护筒，外护筒的底部抵接在裸岩的顶部，外护筒围合形成外筒空间；2)、采用牙轮筒钻朝下环切裸岩，在裸岩中形成环形槽，裸岩中形成岩柱，环形槽环绕在岩柱的外周；3)、在外筒空间中下入内护筒，内护筒的下部嵌入在环形槽中，形成下部段，下部段的外侧壁与环形槽的内侧壁之间具有下部环腔；内护筒的上部显露在外筒空间中，形成上部段，上部段的外侧壁与外护筒的内侧壁之间具有上部环腔；4)、起拔外护筒。解决了海域裸岩大直径旋挖桩护筒埋设难题。
