Deep water pile foundation construction method
The invention relates to a deep water pile foundation construction method. The deep water pile foundation construction method comprises the following construction steps that S1, sludge at a pier position in a deep water area is completely cleaned, and a steel cofferdam is sunk at the pier position; S2, underwater concrete is poured to the bottom of the steel cofferdam, and four positioning rods arranged in a square shape are pre-buried around the outer circumference of a pile hole position; S3, a drilling platform is erected by taking the steel cofferdam as a main support, and a drilling machine is installed on the drilling platform and corresponds to the position of the pile hole position; S4, a guide protective cylinder is placed in the four positioning rods of each pile hole position, and the drilling machine is started to carry out drilling operation through the guide effect of the guide protective cylinder; and S5, a steel reinforcement cage matched with the pile hole position in size is placed in the pile hole position, and then grouting anchor rods are uniformly arranged along the inner wall of the pile hole position. The deep water pile foundation construction method has the effects that the connection strength between a deep water pile foundation and an underground rock layer is improved, and meanwhile, the construction cost of the deep water pile foundation is reduced.
本申请涉及一种深水桩基施工方法，包括以下施工步骤：S1，将位于深水区域的墩位处的淤泥完全清理，在墩位处沉放钢围堰；S2，向钢围堰的底部浇筑水下混凝土，围绕桩孔位的外周圆预埋四根呈正方形排布的定位杆；S3，通过钢围堰作为主支撑搭设钻孔平台，将钻机安装于钻孔平台上并与桩孔位的位置相对应；S4，将导向护筒放置于每个桩孔位的四根定位杆内，启动钻机通过导向护筒的导向作用进行钻孔作业；S5，在桩位孔内放置与其尺寸匹配的钢筋笼，然后沿桩位孔内壁均匀布设注浆锚杆。本申请具有增加深水桩基与地下岩石层之间的连接强度，同时降低深水桩基的施工成本的效果。
