Optimized steel trestle navigation and construction device
The invention belongs to the technical field of municipal bridge engineering, and particularly relates to a method for optimizing navigation clearance of a steel trestle and a construction device.The method comprises the following steps that S1, survey lofting is conducted, specifically, the position of each middle buttress is lofted according to a trestle plane layout diagram; s2, foundation steel pipe piles are driven according to the paying-off positions; s3, the steel pipe piles are connected, and I22a I-shaped steel cross braces are arranged between the steel pipe piles; s4, constructing an upper structure of the trestle, fully paving riffled plates with the thickness of 8 mm on the upper structure, and mounting guardrails on two sides; and S5, circulating construction is conducted, the built steel trestle is used for conducting construction on the remaining sections through the construction method, the underwater navigation clearance can be effectively improved, and the navigation capacity and navigation safety in the river-crossing construction process are greatly guaranteed.
本发明属于市政桥梁工程技术领域，具体的说是一种优化钢栈桥通航净空方法及其施工装置，包括以下步骤：S1：测量放样，按照栈桥平面布置图放样出每一个中支墩位置；S2：基础钢管桩按照放线位置进行钢管桩打设；S3：钢管桩连接，钢管桩之间在中部设置有I22a工字钢横撑；S4：栈桥上部结构施工，其上满铺设8mm厚花纹钢板，两侧安装护栏；S5：循环施工，利用搭设好的钢栈桥通过上述施工方法对余下各段进行，能够有效地提高水下通航净空，大大保证了跨江施工过程中的通航能力和航行安全。
