滕州市城市内涝治理初探

A Preliminary Study on Urban Waterlogging Control in Tengzhou

摘要:

近年来,滕州市暴雨频发,城市内涝严重,影响城市运行。针对积水问题,从城市上游客水进城、城市下游涝水排出、城区排水体系堵点、排水通道缺失等方面查找根源,综合采取上分、下畅、内疏、通堵、补缺等措施,在城市上游分流客水,城市下游提高涝水排出能力,疏通补足城市内部排水的堵点、盲点,内涝治理成效明显。

Abstract:

In recent years, the Tengzhou City has been frequently hit by rainstorms, resulting in serious urban waterlogging which affected urban operation. In view of the waterlogging problem, this paper finds out the root causes from the aspects of the inflow of upstream foreign water into the city, the discharge of downstream waterlogging, the blocking points in the urban drainage system, and the lack of drainage channels. Comprehensive actions such as upstream diversion, downstream unblocking, internal dredging, blocking removal and deficiency supplementation are taken. Specifically, foreign water is diverted upstream of the city, the capacity of discharging downstream waterlogging is improved, and the blocking points and blind spots in the internal urban drainage are dredged and supplemented. The effect of waterlogging control is obvious.
