Problems solved by technology

Theoretically, the limited quantitative flood standard cannot solve the problem of engineering water damage caused by unlimited super-standard floods; earth-stone structure dams cannot resist super-standard floods
At present, there is a lack of disaster prevention and mitigation design theory for auxiliary dam flood diversion of reservoirs and controllable flood diversion of special spillways

Embodiment 1

[0033] Example 1: The dam exceeds the standard flood flood diversion pipe belt, the cage trash rack 4 is placed in the imported hafnium U-shaped groove 3, to prevent floating objects from damaging the geosynthetics and blocking the flood diversion pipe, and the HDPE flap door 5 is placed in the cage trash rack In the gate 4, the flood diversion function is controlled, and the HDPE flap gate 5 is fixed on the upstream inlet end of the flood diversion pipe body 6, and the flood diversion pipe body 6 is buried horizontally on the upper part of the embankment 1 to form a pressurized flow, which increases the flood diversion flow of the unit passing section, and the flood diversion pipe The upstream outlet end of the body 6 is located in the imported hafnium U-shaped groove 3 and the cage trash rack 4, the downstream outlet end of the flood diversion pipe body 6 is placed in the outlet hafnium U-shaped groove 7, and the downstream outlet end of the flood diversion pipe body 6 is arti...

Embodiment 2

[0045] Example 2: During temporary flood diversion for flood fighting and emergency rescue, if the water depth is small or there is no HDPE gate, use barbed wire to tie the inlet end of the flood diversion pipe body 6 as a cage trash rack 4, and use sandbags + non-woven fabrics + iron wires to retain soil or pipes The body protrudes from the upstream slope to replace the inlet U-shaped groove 3, and the flood diversion pipe body 6 protrudes from the downstream embankment slope to replace the outlet U-shaped groove 7 of the flood diversion pipe body 6. If it is necessary to stop flood diversion, it is placed in front of the cage trash rack 4 Strip cloth pressure sandbags replace HDPE flap door 5, others are the same as above.

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...
