Construction method of steel trestle
The invention relates to the technical field of building construction, in particular to a construction method of a steel trestle, which comprises the following steps of: 1, performing construction survey; 2, inserting and driving steel pipe piles, namely uniformly arranging and inserting and driving two rows of steel pipe piles on a riverbed along the direction vertical to the flowing direction ofthe river in the following inserting and driving manner: A1, inserting, dotting and positioning; a2, cofferdam construction; a3, the steel pipe pile is in place; a4, inserting and driving steel pipepiles; a5, the pile head is cut off; a6, the cofferdam is dismantled; 3, connecting the steel pipe piles; 4, mounting an upper structure; and 5, the steel truss girder is installed. The steel trestlehas the effects that the influence of water flow on the steel pipe pile when the steel pipe pile is driven in can be reduced, the steel pipe pile is positioned more accurately, the steel pipe pile isprevented from deviating, the bearing capacity of the steel trestle is guaranteed, and the accident probability is reduced.
本发明涉及建筑施工的技术领域，尤其是涉及一种钢栈桥的施工方法，包括以下步骤：步骤1：施工勘测；步骤2：插打钢管桩，将两排钢管桩沿垂直于河流流动方向均匀排列插打在河床上，插打方式如下：A1:插打点定位；A2:围堰建造；A3:钢管桩就位；A4:插打钢管桩；A5:割除桩头；A6:拆除围堰；步骤3：钢管桩连接；步骤4：上部结构安装；步骤5：安装钢桁梁。本发明具有能够降低水流在钢管桩打入时对钢管桩的影响，使钢管桩的定位更加准确，防止钢管桩发生偏移，保证钢栈桥承重的能力，降低事故发生的概率的效果。
