Abstract

The invention relates to a dam over-standard flood diversion duct tape, and belongs to the technical field of a dam flood diversion hydraulic engineering. The dam over-standard flood diversion duct tape can controllably disperse and divert over-standard flood to farmlands to protect a dam; an outlet of a dynamic floating body, adopts a novel energy dissipation mode and has the advantages of trajectory flow, surface flow and bottom flow; and the dam over-standard flood diversion duct tape is applicable to any topographical geological conditions. The dam over-standard flood diversion duct tape is simple in structure, is rapid and convenient in construction, and low in cost. The dam over-standard flood diversion duct tape adopts the structure that a cage screen (4) is placed in a hafnium U-shaped groove (3) of an upstream inlet; an HDPE (high-density polyethylene) flap valve (5) is fixed outside an inlet of a flood diversion duct body (6); the flood diversion duct body (6) is horizontally buried at the upper part of the dam (1); the downstream end of the flood diversion duct body (6) is connected with a water delivery tape (9) made of an artificial synthetic material; and an outlet of the water delivery tape (9) made of the artificial synthetic material is formed on the dynamic floating body (10). The dam over-standard flood diversion duct tape is applicable to controllable flood diversion and flood-fighting and emergency rescues of embankments and dams.

Description

technical field

[0001] The invention belongs to the technical field of dam flood diversion and conservancy engineering, and in particular relates to a dam superstandard flood diversion pipe belt. Background technique

[0002] In 2013, super-standard floods that could not be resisted by manpower occurred in Heilongjiang. Under the existing water conservancy norms and technical conditions, it is very difficult to achieve the goal of "ensuring the safety of flood fighting and rescue troops" and the safety of dams. The innovation method realizes this goal, has also just solved the worldwide difficult problem that the dam surpasses the standard flood and overflows and breaks and injures people and destroys property. The following cases and difficult problems illustrate that the present invention will produce huge social and economic benefits; the following cases and difficult problems illustrate the present invention Invention is of urgency to safeguard the national economy and t...
