The invention discloses a newly-built large-diameter drainage pipeline and existing drainage main pipeline crossed node structure which comprises a newly-built large-diameter drainage pipeline and an existing drainage main pipeline and further comprises a working well, and the newly-built large-diameter drainage pipeline and the existing drainage main pipeline both penetrate through the side portion of the working well and extend into the working well. An inspection well is arranged at the top of the working well, an octagonal retaining wall is arranged in the working well, a water passing gallery communicated with the newly-built large-diameter drainage pipeline is arranged in the octagonal retaining wall, and an inspection well ladder stand is arranged on the side portion of the water passing gallery and the side portion of the octagonal retaining wall. The newly-built large-diameter drainage pipeline is communicated in the working well through the water passing gallery, an existing drainage main pipeline is communicated through the area, except the water passing gallery, in the working well, and personnel can conduct routine inspection on the interior of the working well through the inspection well and the inspection well ladder stand.
本发明公开新建大直径排水管道与现有排水主管道交叉的节点结构，包括新建大直径排水管道与现有排水主管道，还包括工作井，新建大直径排水管道与现有排水主管道均穿过工作井的侧部延伸至工作井内部，工作井的顶部设置有检查井，工作井内部设置有八边形挡墙，八边形挡墙内部设置有连通新建大直径排水管道的过水廊道，过水廊道和八边形挡墙的侧部设置有检查井爬梯。通过过水廊道将新建大直径排水管道在工作井内部连通，现有排水主管道通过工作井内部除过水廊道以外的区域实现连通，人员可以通过检查井及检查井爬梯对其内部进行常规检查。
