Construction method and auxiliary device for cutting steel pipe pile under riverbed
The invention discloses a construction method and an auxiliary device for cutting a steel pipe pile under a riverbed, and relates to the technical field of underwater engineering construction.The construction method comprises the steps that the outer diameter of the steel pipe pile to be cut and the height from the water surface to the riverbed are measured; a sleeve is manufactured, the sleeve comprises an annular steel pipe section on the upper half portion and a conical steel pipe section on the lower half portion, and an open hole used for sleeving the steel pipe pile is formed in the bottom of the conical steel pipe section; the length of the annular steel pipe section is larger than the height from the water surface to the riverbed, and the gap between the radius of the annular steel pipe section and the radius of the steel pipe pile is not smaller than 0.6 m. And a to-be-cut steel pipe pile is sleeved with the bottom opening of the sleeve from top to bottom, so that the conical steel pipe section is cut into the riverbed, and a dry area working face is formed below the riverbed surface. The invention further discloses an auxiliary device for cutting the steel pipe pile under the riverbed. According to the construction method and the auxiliary device, cutting of the steel pipe piles below the riverbed surface is assisted, a dry area working face is provided, the cutting safety risk is reduced, and the construction cost is reduced.
本申请公开了一种河床下切割钢管桩的施工方法及辅助装置，涉及水下工程施工技术领域，其包含步骤：测量待切割钢管桩外直径、以及水面至河床的高度；制造一个套管，套管包含上半部分的环形钢管段和下半部分的锥形钢管段，锥形钢管段的底部开设用于套设钢管桩的开孔；且环形钢管段的长度大于水面至河床的高度，环形钢管段的半径与钢管桩半径之间的间隙不小于0.6m；将套管的底部开孔从上往下套入待切割的钢管桩，使得锥形钢管段切入河床，在河床面以下形成干区作业面。本申请还公开了一种河床下切割钢管桩的辅助装置。本申请的施工方法及辅助装置，辅助实现河床面以下钢管桩切除，提供干区作业面，降低切割安全风险，减少施工成本。
