Method for follow-up long steel casing construction of pile foundation construction in karst area
The invention provides a method for the follow-up long steel casing construction of the pile foundation construction in a karst area, and relates to the technical field of pile foundation construction. The method for the follow-up long steel casing construction of the pile foundation construction in the karst area comprises the following specific steps of (S1) firstly, determining the position of a pile center point according to a pile foundation design scheme, fixing a pile in the position of the pile center, building four fender piles around the pile center after the position of the pile center is determined, binding a positioning line between every two symmetrical fender piles, and enabling the intersection point of the two positioning lines to coincide with the position of the pile center point; and (S2) after the positions of the pile center and the fender piles are determined, performing pile foundation fixing in the positions of the pile center and the fender piles through concrete, and disassembling the two positioning lines. Rapid construction is performed by adopting a graded follow-up construction method, so that the construction precision of long steel casing construction can be guaranteed, additionally, the overall construction strength in a karst cave area can be guaranteed, the hole wall is firm and stable, the hole collapse situation is avoided, and the construction method is worthy of being widely popularized.
本发明提供岩溶地区桩基施工跟进长钢护筒施工的方法，涉及桩基施工技术领域。该岩溶地区桩基施工跟进长钢护筒施工的方法，包括以下具体步骤：S1.首先根据桩基设计方案确定桩心点的位置，并在其桩心位置定桩，在桩心位置确定之后，在桩心四周建立四个护桩，在对称两个护桩之间各绑定一根定位线，并使两条定位线的交叉点与桩心点位置重合；S2.待桩心与护桩的位置确定之后，对桩心与护桩的位置利用混凝土进行桩基固定，并拆解两条定位线。通过采用分级跟进施工的方法进行快速施工，既可以保证长钢护筒施工的施工精度，同时也能保证在溶洞地区的整体施工强度，使孔壁更加的牢固与稳定，不会出现塌孔的情况，值得大力推广。
