Single-hole water diversion box culvert continuous flow joining method
The invention discloses a single-hole water diversion box culvert continuous flow joining method which comprises the following steps: designing an outer package communicating well with a correspondingsize at the joint of a new box culvert and an old box culvert, dividing the interior of the well into a plurality of compartments, and arranging temporary opening and closing steel gates among the compartments; the water flow direction and water body distribution in all the compartments are controlled by adjusting opening and closing of the steel gates, and therefore water-free operation conditions during construction are achieved. When an old single-hole water diversion box culvert faces an upgrading or local diversion problem, if the water diversion importance of the old single-hole water diversion box culvert does not allow temporary water cut-off construction, connection construction of a new box culvert and an old box culvert and diversion of a local box culvert can be completed by adopting the technology on the premise that the overflowing capacity is not affected. The single-hole water diversion box culvert continuous flow connection construction technology has the beneficial effects that the current water diversion box culvert flow passing capacity is not affected, meanwhile, construction is convenient, water environment pollution is not caused, the construction period isnot affected, and the construction occupied area is small.
本发明公开了一种单孔引水箱涵不断流衔接方法，在新老箱涵的连接处设计一种相应尺寸的外包连通井，井内分多个隔舱，隔舱间设置临时启闭钢闸门。通过调节钢闸门启闭控制水流走向及各隔舱内的水体分布，以此实现施工时的无水作业条件。对于老单孔引水箱涵面临升级或局部改道问题时，若其引水重要性不允许临时断水施工，则可采用该技术在不影响过流能力的前提下完成新老箱涵衔接施工和局部箱涵的改道问题。本发明的单孔引水箱涵不断流衔接施工技术具有不影响现状引水箱涵过流能力的优点，同时具有施工方便、不造成水环境污染、不影响工期、施工占地面积小等优点。
