船台滑道水下桩基及其施工方法技术

本发明专利技术公开了一种船台滑道水下桩基及其施工方法，水下桩基包括PHC管桩、桩帽、桩帽下方的桩接点，所述的桩帽位于PHC管桩的顶端，所述的桩接点伸入PHC管桩内，施工方法步骤如下：a、PHC管桩沉桩：将PHC管桩沉入泥中，PHC管桩的顶端位于水面线以下、泥面线以上；b、PHC管桩处沉放钢套筒，钢套筒的下部沉入泥中，钢套筒的顶端位于水面线以上，使PHC管桩位于钢套筒的空腔内；c、钢套筒的顶端四周建工作平台；d、将钢套筒空腔内的水抽干；e、PHC桩桩头处理；f、桩帽和桩接点施工；g、移走钢套筒。本发明专利技术船台滑道水下桩基及其施工方法采用这样的方式，不仅能适应于各类地层地质，而且能降低造价，缩短施工工期，降低水下作业风险，安全可靠。

Slipway underwater pile and its construction method

The invention discloses a slipway underwater pile and its construction method, pile contact underwater pile including below PHC piles, pile cap, pile cap, pile cap at the top of the pipe pile is located in PHC, contact the PHC into the pile, the construction method comprises the following steps of: A, PHC pipe pile pile: PHC pile will sink into the mud, the top PHC pipe in the water above the line, below the mud line; B, PHC at the pile sinking steel sleeve, the lower part of the steel sleeve into the mud, the top steel sleeve on the surface of the water above the line, the PHC pipe cavity located in the steel sleeve; C, steel sleeve the periphery of the top building work platform; D, the steel sleeve in the cavity draining water; E, PHC pile head processing; F, pile cap and pile joint construction; G, remove the steel sleeve. The invention of slipway underwater pile and its construction method used in this way, not only can adapt to all kinds of geological strata, but also can reduce the cost, shorten the construction period, reduce the operation risk of water, safe and reliable.
