Crossing structure for crossing riverway through steel pipe and construction method
The invention relates to the technical field of pipeline laying, in particular to a crossing structure of a steel pipe crossing a riverway and a construction method, and the crossing structure comprises the following steps: S1, arranging at least two fixed piles on the riverway along the river width direction of the riverway; s2, a water retaining weir wall is obliquely arranged in the downstream direction of the river channel with the fixing piles as base points; s3, a ditching pontoon is transferred into the low-speed flow channel, and a pipe ditch is dug; s4, a pipe lifting pontoon is adjusted in, the pipeline is lifted into the dug pipe ditch, and a pouring pontoon is adjusted in to pour a concrete filling layer and a soil layer into the pipe ditch; s5, the water retaining weir wall is dismantled or removed, so that a low-speed flow channel formed by the new water retaining weir wall and a low-speed flow channel formed by the front water retaining weir wall coincide in area, and the pipeline pre-construction area is in butt joint; s6, the step S3 and the step S4 are repeated, and in the step S4, the two sections of pipelines hoisted to the pipe ditch are in butt joint; and S7, repeating S5 and S6 in sequence. The river-crossing pipeline laying device has the effect of being suitable for river-crossing pipeline laying of rivers with narrow and small river channels and rapid flow velocity.
本申请涉及管道铺设技术领域，尤其是涉及一种钢管穿越河道的穿越结构及施工方法，其包括以下步骤S1:于河道上，沿河道的河宽方向打设至少两根固定桩；S2:以固定桩为基点，于河道下游方向倾斜设置挡水堰墙；S3:调入挖沟浮船于低速流道，挖设管沟；S4:调入吊管浮船，将管道吊至挖设的管沟内，调入浇灌浮船朝管沟内浇筑混凝土填充层、土层；S5:拆除或移除挡水堰墙，使得新挡水堰墙形成的低速流道和前挡水堰墙形成的低速流道区域重合，且管道预施工区域对接；S6：重复步骤S3、S4，并于其中的S4中先将两段吊至管沟的管道进行对接；S7：依次重复S5、S6。本申请具有适应河道窄小且流速湍急的河流的跨河管道铺设的效果。
