Method for locking steel pipe pile cofferdam structure
The invention provides a method for locking and buckling a steel pipe pile cofferdam structure, and belongs to the field of locking and buckling steel pipe pile cofferdams, and the method for locking and buckling the steel pipe pile cofferdam structure comprises the specific steps of component selection, component processing, construction lofting and positioning, guide frame installation, hole guiding and forming, steel pipe pile inserting and driving, cofferdam closure and inner support installation, cofferdam cleaning and cofferdam foundation pit bottom sealing. The cofferdam structure is reasonable in layout, the main structure of the lock catch steel pipe pile cofferdam is the supporting steel pipe piles, the lock catches, the horizontal supports and the bottom sealing concrete, cofferdam water stopping mainly depends on rock-soil mass jet grouting pile water stopping curtains on the outer side of the cofferdam and water stopping materials poured into the lock catches, and the water stopping effect is achieved; dry construction of the underwater deep-buried bearing platform operation of the large bridge is achieved through the four stages of steel pipe pile inserting and driving of the lock catch steel pipes, cofferdam closure and inner support installation, cofferdam cleaning and cofferdam foundation pit bottom sealing.
本发明提供一种锁扣钢管桩围堰结构方法，属于锁扣钢管桩围堰领域，该锁扣钢管桩围堰结构方法具体步骤为构件选用、构件加工、施工放样与定位、安装导向框、引孔与成孔、钢管桩插打、围堰合龙以及内撑安装、围堰清理和围堰基坑封底。本发明围堰结构布局合理，锁扣钢管桩围堰的主要结构是支护钢管桩、锁扣、水平支撑和封底混凝土，围堰止水主要是靠在围堰外侧岩土体旋喷桩止水帷幕和锁扣内灌注止水材料，达到止水的效果，通过对锁扣钢管的钢管桩插打、围堰合龙以及内撑安装、围堰清理以及围堰基坑封底四个阶段来实现大型桥梁水中深埋承台作业的干法施工。
