Construction method for steel trestle in torrent exposed hard rock area
The invention relates to the field of bridge construction, in particular to a construction method for a steel trestle in a torrent exposed hard rock area, which comprises the following steps: installing and anchoring a self-floating construction platform at a specified position in water, and installing a double-layer positioning guide frame on the side wall of the self-floating construction platform; a crawler crane is used on the land surface steel trestle for lowering the steel casing to the riverbed surface along the positioning guide frame, and a slag removal hole is formed in the bottom of the steel casing; drilling below a riverbed along the interior of the steel casing to form a steel pipe pile hole; concrete is poured into the steel pipe pile hole, the steel pipe pile is inserted into the concrete, and the steel casing is pulled out after the concrete is solidified; and after distributive girders and bailey girders are installed on the tops of the steel pipe piles and a bridge deck is laid, the steps are repeated to complete construction of the steel trestle. By implementing the scheme, the problems that a traditional construction method is long in construction period and high in cost are solved.
本发明涉及本发明涉及桥梁施工领域，具体涉及一种用于在急流裸露硬岩区域钢栈桥的施工方法，在水中指定位置安装锚固自浮式施工平台，并在自浮式施工平台的侧壁安装有双层的定位导向架；在陆面钢栈桥上使用履带吊将钢护筒沿定位导向架下放至河床面，并在钢护筒的底部开设清渣孔；沿钢护筒内部向河床以下钻孔形成钢管桩孔；沿钢管桩孔内浇筑混凝土，并将钢管桩插打入混凝土内，待混凝土凝固后拔出钢护筒；在钢管桩的顶部安装分配梁、贝雷梁并铺设桥面后，再重复上述步骤以完成钢栈桥的施工。通过实施本方案，以解决传统施工方法存在的施工周期长、成本大的问题。
