Existing bridge T-joint steel trestle and construction method
The invention discloses a T-joint steel trestle using an existing bridge and a construction method, and relates to the technical field of bridge construction, and the construction method comprises the following steps: constructing a steel trestle foundation, performing manual hole digging pile foundation construction or low-frame rotary drilling hole-forming pile foundation construction at a brake pier or a steep position of a side slope, and performing embedded enlarged foundation construction at a middle fixed pier. The construction method has the beneficial effects that the safety risk caused by building the steel trestle crossing the existing line is avoided, meanwhile, the steel pipe stand columns of the steel trestle adopt the standard knots with a certain modulus, the steel pipe stand columns are connected through the high-strength bolts, construction of the steel trestle is accelerated, the distribution beams and the bailey beams of the steel trestle are synchronously assembled outside the trestle, and the construction efficiency is improved. Only the installation time is occupied, rapid construction of the steel trestle is guaranteed, on the premise that the practical function of the steel trestle is guaranteed, the steel trestle is pulled through in a linear mode, meanwhile, the steel trestle is provided with a certain gradient to be connected with a side slope, and on the premise that the construction cost is reduced, the construction workload is reduced.
本发明公开了一种利用既有桥梁T接钢栈桥及施工方法，涉及桥梁施工技术领域，包括以下步骤：施工钢栈桥基础，制动墩或者边坡较陡处进行人工挖孔桩基础施工或低架旋挖钻成孔桩基施工，中间固定墩处进行埋置式扩大基础施工。本发明的有益效果是：避免跨越既有线搭建钢栈桥造成安全风险，同时通过钢栈桥的钢管立柱选用一定模数的标准节，钢管立柱与钢管立柱之间采用高强螺栓连接，加快钢栈桥的施工，钢栈桥的分配梁和贝雷梁在栈桥外同步组拼，仅占用安装时间，保证钢栈桥的快速施工，在保证钢栈桥的实用性功能的前提下，采取直线式拉通钢栈桥，同时钢栈桥设置一定坡度与边坡衔接，在降低施工成本的前提下，减少施工作业量。
