Steel trestle foundation construction method under complex geological conditions
The invention provides a steel trestle foundation construction method under complex geological conditions. The steel trestle foundation construction method comprises the following steps that a bench type short trestle is erected; a drilling platform of the same type is built on one side of the short trestle, and the drilling platform is connected with the short trestle; foundation pile construction of the high trestle is conducted on the drilling platform, a rotary drilling guide hole is adopted for a foundation pile, a bond-wrapped concrete-filled steel tube anchoring pile is poured, and after the foundation pile construction of the high trestle is completed, the drilling platform is dismantled; and the high trestle is erected, and after the high trestle is erected, the short trestle is dismantled. According to the construction method, the short trestle is firstly erected in the dry season, the high trestle anchor pile construction is conducted through the short trestle, the situation that the high trestle and the short trestle coexist is formed in the dry season, and the high trestle has enough flood-fighting capacity in the flood season.
本发明提供一种复杂地质条件下钢栈桥基础施工方法，包括以下的步骤：搭设板凳式矮栈桥；在矮栈桥的一侧搭建同类型钻孔平台，所述钻孔平台和矮栈桥相接；在钻孔平台上进行高栈桥的基桩施工，基桩采用旋挖钻引孔，浇筑握裹式钢管混凝土锚固桩，高栈桥的基桩施工完成后，拆除钻孔平台；搭设高栈桥，在高栈桥搭设完毕后，拆除矮栈桥。本发明通过枯水期先搭设矮栈桥，并利用矮栈桥进行高栈桥锚桩施工，枯水期形成高矮栈桥共存的局面，洪水期高栈桥具备足够的抗洪能力。
