Rock riverbed deepwater steel trestle reinforcing overturn-preventing structure and construction method thereof
The invention discloses a rock riverbed deepwater steel trestle reinforcing overturn-preventing structure and a construction method thereof, and effectively solves the problems that when a steel trestle is erected on a rock riverbed, the steel trestle is difficult to deform due to insufficient riverbed covering layers, weak anchoring force and poor stability due to the fact that a plurality of anchoring piles are installed in riverbed bedrock and a connecting structure with a trestle structure needing to be reinforced. And the horizontal overturning moment resistance stability is poor. Meanwhile, when the method is adopted, drilling machine hole guiding and anchoring do not need to be conducted on the steel buttress foundation in the erecting process of the main trestle, investment of overwater operation equipment is reduced, the trestle erecting time is greatly shortened, the anchoring pile trestle reinforcing structure is constructed on the upper half portion of the erected trestle, normal use of the trestle is not affected, and the construction period is shortened. And the efficiency of construction equipment is improved, the project investment is reduced, and the construction period is shortened.
本发明公开了一种岩质河床深水钢栈桥加固防倾覆结构及其施工方法，通过深入河床基岩内安装的多根锚固桩，以及与需加固的栈桥结构的连接结构，有效解决了岩质河床上搭设钢栈桥时由于河床覆盖层不足，锚固力弱，抗水平倾覆力矩稳定性差的问题；同时，采用本申请方法时候，主栈桥在搭设过程中不需要对钢支墩基础进行钻机引孔锚固，减少了水上作业设备的投入，极大地减少了栈桥搭设时间，在搭设好的栈桥上半幅施工锚固桩栈桥加固结构，既不影响栈桥的正常使用，又提高施工机具的效率，降低了工程投资，节约了工期。
