Construction method for high-speed deepwater bare rock geological pile foundation in mountainous area
The invention discloses a mountainous area high-speed deepwater bare rock geological pile foundation construction method which comprises the following steps: firstly placing a large-aperture steel casing at a corresponding position at the bottom of a riverbed, then performing pile hole construction of a pile foundation in water under the guidance of the large-aperture steel casing by using a drilling machine, and then buckling and inserting a standard-aperture steel casing at the upper end part of the large-aperture steel casing after the construction is completed, the adjacent standard-aperture steel casings are fixedly connected, the last standard-aperture steel casing extends out of the water surface, then steel bar construction and concrete pouring construction of the underwater pile foundation are conducted in sequence, the construction safety is improved, the method has the advantages of being safe, economical and environmentally friendly, the economic, progress and social benefits are obvious, and the construction period is shortened. Good popularization and application values are realized.
本发明公开了一种山区高速深水裸岩地质桩基施工方法，该在河床底部对应位置先放置大孔径钢护筒，然后用钻机在大孔径钢护筒导引下进行水中桩基的桩孔施工，施工完成后然后采用标准孔径钢护筒扣插在大孔径钢护筒的上端部，相邻标准孔径钢护筒之间固定连接，并使得最后一根标准孔径钢护筒伸出水面，然后依次进行水中桩基的钢筋施工和混凝土浇筑施工，本发明提高了施工安全性，具有安全、经济、环保的特点，经济、进度和社会效益明显，具有较好的推广应用价值。
