Deep-water shallow-covering-layer full-rock-socketed bridge foundation construction method
The invention discloses a deep-water shallow covering layer full-rock-socketed bridge foundation construction method which is sequentially carried out according to the following steps that firstly, a steel trestle and a steel platform are built on water, and then a lock catch steel pipe pile cofferdam is constructed outside the side boundary of a designed bearing platform; pile foundation equipment and constructing pile foundations are installed on a steel platform, hole guiding and re-vibration are synchronously conducted on the lock catch steel pipe pile cofferdam, and a pipe and a hole are filled with fillers at a certain height to solidify the bottom of the cofferdam; a temporary platform is erected through a gap between the steel trestle and the steel platform, grouting equipment is installed, and curtain grouting and water stopping are conducted on shallow coverage; the steel platform in the steel cofferdam is removed, water is pumped, and purlin supports are installed step by step until a water-free operation environment is formed in the cofferdam; a steel casing for pile foundation construction is cut off, excavation equipment is lowered, and a shallow covering layer and soft stone are cleaned; and a construction intercepting ditch is used for intercepting water, if water leaks in the cofferdam, plugging is conducted in time, and curtain grouting water stopping and the like are conducted in the cofferdam.
本发明公开一种深水浅覆盖层全嵌岩桥梁基础施工方法，按照以下步骤顺序进行：首先在水上建立钢栈桥和钢平台，然后沿设计承台边线外施工锁扣钢管桩围堰。在钢平台上安装桩基设备，施工桩基础，同步对锁扣钢管桩围堰进行引孔、复振，并在管内和孔内将填充物填充一定高度，使围堰底部固结。利用钢栈桥和钢平台之间的空隙，搭设临时平台，安装注浆设备，对浅覆盖进行帷幕注浆止水。拆除钢围堰内钢平台，抽水逐级安装围檩支撑，直至在围堰内形成无水作业环境。割除桩基施工用钢护筒，下放开挖设备，对浅覆盖层和软石进行清理。施工截水沟用于截水，如果围堰内有漏水及时进行封堵，并在围堰内也进行帷幕注浆止水等。
