Bearing platform foundation construction method and near-shore cofferdam structure
The invention belongs to the technical field of bridge construction, and discloses a bearing platform foundation construction method and a near-shore cofferdam structure. The bearing platform foundation construction method comprises the steps that S1, surveying and setting-out are conducted on a bank slope, and an outer contour line is determined; s2, the outer contour line is used as the outer edge, and a step structure is excavated on the bank slope in the direction away from the land; s3, fixing piles are arranged at the two end points of the outer contour line; s4, the cofferdam is fixed to the step structure along the outer contour line, and the two ends, in the outer contour line direction, of the cofferdam are fixedly connected with the two fixing piles correspondingly; s5, a horizontal reinforcing beam is arranged on the cofferdam in the direction of the outer contour line, and the two ends of the horizontal reinforcing beam are fixedly connected with the two fixing piles correspondingly; s6, fixing piles are anchored on the bank slope; s7, pouring and filling concrete on the step structure; and S8, drilling pile construction is conducted. According to the near-shore cofferdam structure, the topographic condition of the near-shore slope can be fully utilized, and the structural strength and the horizontal resistance of the cofferdam are remarkably improved.
本发明属于桥梁施工技术领域，公开了一种承台基础施工方法及临岸围堰结构。该承台基础施工方法包括：S1、在临岸斜坡上进行测量放线，并确定外轮廓线；S2、以外轮廓线为外缘，沿背离陆地的方向在临岸斜坡上开挖台阶结构；S3、在外轮廓线的两个端点上设置固定桩；S4、将围堰沿外轮廓线固定在台阶结构上，并将围堰沿外轮廓线方向的两端分别与两个固定桩固定连接；S5、在围堰上沿外轮廓线的方向设置水平加固梁，将水平加固梁的两端分别与两个固定桩固定连接；S6、将固定桩锚固在临岸斜坡上；S7、向台阶结构上浇筑填筑混凝土；S8、进行钻孔桩施工。该临岸围堰结构能够充分利用临岸斜坡的地形条件、显著提高围堰的结构强度和水平抵抗力。
