Construction method for pulling out water concrete pipe pile
The invention provides a construction method for pulling out a water concrete pipe pile, which comprises the following steps: step 1, hoisting a pile pulling tool to the position of one PHC pipe pile by a pile driving barge, and enabling the position of the pile pulling tool to be matched with the position of the PHC pipe pile; secondly, the pile is sunk to the bottom elevation position of the PHC pipe pile through a pile pulling tool, and the pile pulling tool lifts the inner sleeve and the PHC pipe pile together through friction force between the inner sleeve and the PHC pipe pile; thirdly, the pile pulling tool and the PHC pipe pile are lifted ashore together through a lifting hook of a pile driving barge; fourthly, the PHC pipe pile is taken out; and fifthly, the outer sleeve is pulled out and hoisted ashore through a vibratory hammer, and the inner sleeve and the outer sleeve are assembled for pile pulling construction of the next pile. The pile pulling tool is used for hoisting the inner sleeve and the single PHC pipe pile together by means of friction force between the inner sleeve and the PHC pipe pile, the pile pulling tool and the single PHC pipe pile are hoisted ashore together by means of a lifting hook of a pile driving barge, the pile pulling process is simpler and more convenient, and the pile pulling efficiency is high.
本发明提供了一种拔出水上混凝土管桩的施工方法，包括以下步骤：步骤一、由打桩船将拔桩工具吊至一根PHC管桩位置，使拔桩工具的位置与本根PHC管桩的位置吻合；步骤二、将拔桩工具沉桩至所述PHC管桩的底标高位置，并且拔桩工具依靠内套管和PHC管桩之间的摩擦力将内套管和PHC管桩一同吊起；步骤三、用打桩船的吊钩将拔桩工具与PHC管桩一起吊上岸；步骤四、取出PHC管桩。步骤五、用振动锤将外套管拔出吊上岸，拼装内外套管进行下一根桩的拔桩施工。本发明使用拔桩工具依靠内套管和PHC管桩之间的摩擦力将内套管和单根PHC管桩一同吊起，借助打桩船的吊钩把拔桩工具同单根PHC管桩一并吊上岸，拔桩过程更简便，拔桩效率高。
