Construction method of sinking type large-diameter multi-compartment barrel and pile foundation combined type artificial island

XIAO ZHONG / LIU YING

Abstract

The invention relates to a construction method of a sinking type large-diameter multi-compartment barrel and pile foundation combined type artificial island. The basic composition units of the artificial island are a multi-compartment barrel and a pile foundation located below the multi-compartment barrel, wherein the multi-compartment barrel comprises a large-diameter cylinder and an inner partition plate, the inner partition plate comprises a main partition plate and an auxiliary partition plate, and a guide pipe used for driving the pile foundation is arranged at the intersection of the main partition plate and the auxiliary partition plate. The construction method of the artificial island comprises two types. One of the construction method comprises the following steps that the multi-compartment barrel is manufactured by adopting steel, and the large-diameter cylinder is connected with the inner partition plate in a welded mode; and the multi-compartment barrel is integrally transported out, floated to a construction site and sunk to a specified depth. The other construction method comprises the following steps that the large-diameter cylinder and the inner partition plate areprefabricated separately by adopting the multi-compartment barrel of reinforced concrete, and are transported to a construction site in a floating mode, the large-diameter cylinder is firstly sunk toa specified depth, then the inner partition plate is placed and the joint is cast in place; and the pile foundation is placed in the guide pipe, and then the pile is driven into the specified depth. The method is suitable for soft soil foundation and deep water condition, and is convenient to construct.

本发明涉及沉入式大直径多隔舱筒与桩基组合式人工岛的施工方法，所述的人工岛的基本组成单元为多隔舱筒和位于多隔舱筒下方的桩基，所述的多隔舱筒包括大直径圆筒、内隔板，内隔板包括主隔板和副隔板，二者相交处设置有用以打设桩基的导管，人工岛的施工方法包括两种：采用钢材制作多隔舱筒，大直径圆筒和内隔板焊接相连；多隔舱筒整体出运，浮运至施工地点，下沉至指定深度；采用钢筋混凝土的多隔舱筒，分别预制大直径圆筒和内隔板，浮运至施工地点，先将大直径圆筒下沉至指定深度，再安放内隔板并现浇接头；将桩基置于导管内，再将桩打入指定深度。本发明适用于软土地基和深水条件、施工便捷。
