Annular suction bucket transition section foundation structure and mounting method thereof
The invention discloses an annular suction bucket transition section foundation structure and a mounting method thereof, the annular suction bucket transition section foundation structure comprises a single pile foundation, an annular suction bucket, an outer sleeve, a transition section, an outer platform, a ladder stand and a cable pipe, the single pile foundation is vertically arranged, and the lower part of the single pile foundation penetrates into a seabed. The single pile foundation is sleeved with the outer sleeve, a grouting cavity is formed between the inner side wall of the outer sleeve and the outer side wall of the single pile foundation, and a grouting hole communicated with the grouting cavity is formed in the top of the outer sleeve. The annular suction barrel is arranged outside the outer sleeve and is coaxial with the outer sleeve, the lower end of the outer sleeve penetrates into the inner side of the annular suction barrel, the outer sleeve and the annular suction barrel are fixedly connected into a whole, and a drain valve is arranged at the top of the annular suction barrel. The lower end of the transition section is fixedly connected with the top of the outer sleeve, and the outer platform is arranged outside the top of the transition section. The bearing capacity of the old single-pile foundation is effectively improved, the bearing capacity and stability of the single-pile foundation are remarkably enhanced, a high-power fan can be further upgraded, the original single-pile foundation does not need to be removed in later transformation, construction is rapid, and manufacturing, construction and installation cost is saved.
本发明公开了一种环形吸力桶过渡段基础结构及其安装方法，包括单桩基础、环形吸力桶、外套筒、过渡段、外平台、爬梯和线缆管，单桩基础竖向布置，下部贯入海床内。外套筒套设在单桩基础外部，外套筒的内侧壁与单桩基础的外侧壁之间形成注浆空腔，外套筒的顶部具有与注浆空腔相通的注浆孔。环形吸力桶设置在外套筒外部，环形吸力桶与外套筒同轴布置，外套筒下端贯入环形吸力桶内侧，外套筒与环形吸力桶固定相连成一体，环形吸力桶顶部设有排水阀。过渡段下端与外套筒顶部固定相连，外平台设在过渡段顶部外侧。本发明有效提高旧单桩基础承载力，单桩基础承载力及稳定性显著增强，利于进一步升级大功率风机，后期改造无需移除原有单桩基础，施工快速，节省制造、施工及安装费用。
