Environment-friendly anti-collapse temporary bridge and construction method
The invention relates to the technical field of temporary bridges, in particular to an environment-friendly anti-collapse temporary bridge and a construction method.The construction method comprises the steps that S1, a bridge floor body is spliced, and the riverbed construction position is determined; s2, performing protective tunneling on the iron sheet barrel, and adjusting the set tunneling rotating speed in real time; s3, adjusting a set tunneling rotating speed or a sand pumping matching coefficient according to the real-time river water turbidity and the initial river water turbidity; s4, underwater concrete is poured through a cavity in the supporting steel pipe column; and S5, the two adjacent supporting steel pipe columns are welded through angle steel for transverse reinforcement. The bridge floor collapse is avoided by supporting and pulling the temporary floating bridge, the floating, pulling and supporting integrated temporary bridge is achieved, an overall underwater construction scheme is adopted, the construction work amount is reduced, intelligent coordinated construction can be achieved by dividing construction of independent riverbed construction positions, and the construction efficiency is improved. The construction efficiency of the temporary bridge is guaranteed, and meanwhile the influence on the river ecology of a construction area is reduced.
本发明涉及临时桥梁技术领域，尤其涉及一种环保型防塌陷临时桥梁及施工方法，包括，步骤S1，拼接桥面主体确定河床施工位置；步骤S2，铁皮桶防护掘进，对设定掘进转速进行实时调整；步骤S3，根据实时河水浊度与初始河水浊度对设定掘进转速或抽沙匹配系数进行调整；步骤S4，通过支撑钢管柱内部的空腔浇筑水下混凝土；步骤S5，使用角钢焊接两相邻的支撑钢管柱进行横向加固。本发明通过对临时浮桥进行支撑以及牵拉避免桥面塌陷，实现浮、牵、支一体化临时桥梁，并采用整体水下施工方案，减少施工工程量，通过对单独河床施工位置进行划分施工，能够实现智能协调施工，在保障临时桥梁搭建效率的同时减少对施工区域河流生态的影响。
