Dry operation method pile jumping construction technology for reinforced concrete rotary excavating pile in weakly weathered rock stratum
The invention discloses a pile jumping construction technology for a reinforced concrete rotary excavating pile in a weakly weathered rock stratum through a dry operation method, and relates to the technical field of reinforced concrete rotary excavating pile construction. In order to guarantee the pile forming quality and shorten the construction period as much as possible, a pile jumping method is adopted for construction, reinforced concrete rotary excavating piles are constructed in two sequences, first sequence piles are constructed in each area, then second sequence piles are constructed, and the second sequence piles are lagged behind the first sequence piles by 5-6; the sequence piles I and the sequence piles II are arranged at intervals and are integrally arranged in a quincunx shape, the distance is 0.9 m, the axle distance is 0.44 m, and the pile diameter is 1 m; the construction process of each pile comprises the following steps: S1, surveying and setting out; s2, pile casing burying; s3, a drilling machine is in place; s4, drilling to form a hole; s5, hole cleaning; s6, a reinforcement cage is manufactured and hoisted; s7, the guide pipe is hoisted; s8, concrete pouring; and S9, the machine is moved, and the next pile is poured. The construction speed of the rotary excavating pile can be increased, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种弱风化岩层中钢筋混凝土旋挖桩干作业法跳桩施工工艺，涉及钢筋混凝土旋挖桩施工技术领域。为保证成桩质量及尽可能缩短工期，采用跳桩法施工，将钢筋混凝土旋挖桩分两序施工，每个区域先施工Ⅰ序桩，再施工Ⅱ序桩，Ⅱ序桩滞后Ⅰ序桩5～6根；I序桩与II序桩间隔设置，整体呈梅花形布置，间距为0.9m，轴距为0.44m，桩径为1m；每根桩的施工工艺包括以下步骤：S1：测量放样；S2：护筒埋设；S3：钻机就位；S4：钻进成孔；S5：清孔；S6：钢筋笼制作与吊放；S7：吊放导管；S8：混凝土浇筑；S9：移机，浇筑下一根桩。本发明可以提高旋挖桩的施工速度，缩短施工周期，降低施工成本。
