Scheme for additionally arranging central ditch in tunnel without interrupting traffic and rapid construction method
The invention provides a scheme for additionally arranging a central ditch in a tunnel without interrupting traffic and a rapid construction method. The method comprises the following steps that S1, setting-out is carried out on a road surface to determine the position of the central ditch; S2, a road surface structure layer and an inverted arch backfill body are quickly broken to form a central ditch groove; S3, the surfaces of pipe joint bayonets of prefabricated concrete members are coated with a binder, and the prefabricated concrete members are hoisted and placed into the central ditch groove; S4, the central ditch is formed by butting two adjacent prefabricated concrete members; S5, a gap between the central ditch and the wall surface of the central ditch groove is filled; S6, transverse drainage grooves are transversely excavated at certain gradient values between existing roadside ditches on the two sides of the tunnel and the central ditch groove respectively; S7, transverse drainage pipes are placed in the transverse drainage grooves, one ends of the transverse drainage pipes are connected with existing side drainage ditches, and the other ends of the transverse drainagepipes are connected into reserved holes of the central ditch; and S8, the excavated road surface is restored. According to the scheme, the technical problem that when the drainage ditches are re-arranged in the tunnel, traffic passage is influenced due to long-time road interruption construction can be solved.
本发明提供一种不中断交通的隧道增设中心沟方案及快速施工方法，包括以下步骤：S1.在路面放线确定中心沟位置；S2.快速破除路面结构层及仰拱回填体，形成中心沟沟槽；S3.将预制混凝土构件的管节卡口表面涂抹粘结剂，吊装放进中心沟沟槽内；S4.通过对接相邻两节预制混凝土构件，形成中心沟；S5.填充中心沟与中心沟沟槽壁面之间的空隙；S6.在隧道两侧的既有路侧边沟与中心沟沟槽之间，分别以一定坡度值横向开挖横向排水沟槽；S7.在横向排水沟槽内部放置横向排水管，使横向排水管一端与既有侧排水沟相连接，另一端接入中心沟的预留孔洞内；S8.对开挖路面进行恢复；本发明可以解决存在的在隧道中重新排水沟时，长时间断道施工会影响交通通行的技术问题。
