Flow guide structure suitable for inverted siphon construction and construction method thereof
The invention provides a diversion structure suitable for inverted siphon construction, an upstream cofferdam and a downstream cofferdam are arranged on the upstream side and the downstream side of a river channel where an inverted siphon section construction working face is located in an interception mode respectively, and a drainage structure is arranged in the same direction in the flowing direction of the river channel. An upstream straight pipe section and a downstream straight pipe section which penetrate through the upstream cofferdam and the downstream cofferdam to conduct water flow are arranged at the two ends of the drainage structure respectively, the axis of the upstream straight pipe section and the axis of the downstream straight pipe section are located on the same straight line, and a middle bent pipe section is connected between the upstream straight pipe section and the downstream straight pipe section through a rotating flange. According to the drainage structure, under the connecting action of the rotating flanges connecting all the straight pipe sections and the middle bent pipe section, the middle bent pipe section can rotate around the axes of the upstream straight pipe section and the downstream straight pipe section, and therefore the middle bent pipe section is rotated to the left side area and the right side area of a construction working face; therefore, it can be guaranteed that enough construction space is provided during construction of the inverted siphon section of each side area, and the construction progress and quality are guaranteed.
本发明提供了一种适用于倒虹吸管施工的导流结构，在倒虹吸管段施工作业面所在河道的上下游侧分别拦截设置上游围堰和下游围堰，所述河道的流向方向上同向设置泄水结构，所述泄水结构的两端分别设置穿过上游围堰和下游围堰对水流导通的上游直管段和下游直管段，所述上游直管段与下游直管段的轴线在同一直线上，且两者之间通过旋转法兰连接中部弯管段。本发明通过泄水结构在连接各直管段与中部弯管段之间的旋转法兰连接作用下，中部弯管段可围绕上游直管段和下游直管段的轴线旋转，并以此将中部弯管段转至施工作业面的左右两侧区域，从而能够保证在各侧区域的倒虹吸管段的施工时皆具备足够的施工空间，保证施工进度和质量。
