Easy-to-recycle fluidization anti-drag pile pulling construction method
The invention provides an easy-to-recycle fluidization anti-drag pile pulling construction method. The easy-to-recycle fluidization anti-drag pile pulling construction method comprises the following steps of (1) during pile pulling, moving a pile unloading ship first, so that the top of a steel pile enters a stern groove; (2) starting a hydraulic cylinder 8, so that a movable tensioner and a fixed tensioner tightly hold the steel pile; (3) turning on a high-pressure water pump so as to inject water into the steel pile through a high-pressure pipe, spraying fluid at high speed through a jet flow channel under the action of water pressure, and fluidizing soil on the interface of the steel pile and a soil body after the fluid is sprayed out, so that the soil body in a small range around the steel pile is loosened and emerges from the top of a seabed; (4) turning on rotating switches of the movable tensioner and the fixed tensioner after fluidization is conducted for 10 to 20 seconds, and rapidly unearthing the steel pile along with the rotation of the tensioners; and (5) grabbing the steel pipe through a gripper on the tail end of a suspension arm after the steel pile is completely unearthed, then releasing the tensioning force of the movable tensioner and the fixed tensioner, and unloading the steel pile on the deck of a ship body, so that the pile pulling process is completed.
本发明提供了一种易回收的流化减阻拔桩的施工方法，包括如下步骤：1)拔桩时，先移动卸桩船使钢桩顶部进入船尾凹槽：2)开启液压缸8，使可活动张紧器和固定张紧器抱紧钢桩；3)打开高压水泵，通过高压管往钢桩内注水，在水压作用下，流体将经射流道高速喷出；流体喷出后使得钢桩和土体界面的土壤流态化，使得钢桩周围小范围土体松动，并从海床顶部冒出；4)流化10～20秒后，开启活动张紧器和固定张紧器的转动开关，随着张紧器转动，钢桩快速出土；5)待钢桩完全出土，通过吊臂末端的抓手抓紧钢桩，然后卸去可活动张紧器和固定张紧器的张紧力，将钢桩卸放至船体甲板上，完成拔桩过程。
