Construction method of deeply-buried water platform bored piles
The invention relates to the field of building construction and provides a construction method of deeply-buried water platform bored piles to solve the problem that when bored piles are constructed inthe prior art, steel pile casings are inconvenient to use and cannot be transferred quickly. The construction method of the deeply-buried water platform bored piles comprises the steps that the elevation of the top surface of a platform is set to be basically the same as the elevation of an original mud ground, and reserved steel casing descending openings are formed at the position 2m below theelevation of the top surface of a construction platform to be used for driving and descending of steel casings; the steel casings are lowered in place twice; each drilling machine is provided with twosteel casings; after bored pile concrete is poured on the field, the steel casings are pulled out before initial setting of the concrete and are transferred to the next pile position to be driven; and the drilling machine is transferred to the driven steel casings to conduct drilling, and then concrete is poured at the current position. The construction method has the beneficial effect that construction of bored piles in a water environment can be conveniently and efficiently completed.
本发明涉及建筑施工领域，旨在解决现有的钻孔桩施工中钢护筒实用不便、周转慢的问题，提供一种水上深埋式承台钻孔桩施工方法，设置承台顶面标高与原始泥面标高基本持平，在施工平台顶标高下2m处设置预留钢护筒下放口，用于钢护筒的施打下放；钢护筒分两次下放到位：每台钻机配备两根钢护筒；现场在钻孔桩混凝土浇筑完成，混凝土初凝前进行钢护筒拔除作业，将该钢护筒拔出，并转移到下一个桩位进行钢护筒施打；同时钻机移位至另一个已施打的钢护筒处进行该处的钻孔作业，然后浇筑该位置的混凝土。本发明的有益效果是能够方便高效地完成水环境的钻孔桩的施工作业。
