Problems solved by technology

Theoretically, the limited quantified flood standard cannot solve the problem of engineering water damage caused by unlimited super-standard floods; embankments with earth-rock structures cannot resist super-standard floods
At present, there is also 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

[0031] Embodiment 1: The dam exceeds the standard flood flood diversion siphon belt, which includes the trash rack 2 installed outside the inlet of the siphon body 5-1 in the upstream inclined section to prevent floating objects from damaging the geosynthetics and blocking the siphon, and the flap door 3 is installed in the upstream inclined section The outer side of the inlet of the siphon body 5-1 is convenient to close the non-siphon flow. The butterfly valve 4 is installed on the inner side of the inlet of the siphon body 5-1 in the upstream inclined section to realize the lower flood level through the siphon flood discharge. 1 On the upstream slope, the siphon body 5-1 of the upstream inclined section is connected with the siphon body 5-2 of the horizontal section in the dam, the siphon body 5-1 of the upstream inclined section is fixed on the upstream pier 7-1, and the siphon body 5-1 of the horizontal section in the dam -2 is connected with the siphon body 5-3 of the dow...

Embodiment 2

[0043] Embodiment 2: During flood fighting and rescue and temporary flood diversion, use Pe, Pvc, Pp pipes as the siphon body 5, without the need for the pier 7, if there is no flap door, the barbed wire can be tied to the inlet end of the siphon body 5-1 of the upstream inclined section as the trash rack 2. Use sandbags with colored strips at the entrance to close the flood diversion, and the others are the same as above.

Abstract

The invention discloses a dam over-standard flood diversion siphon belt and belongs to the technical field of dam flood diversion water conservancy projects. The dam over-standard flood diversion siphon belt can achieve farmland controllable floor diversion over-standard flood dam protection and dynamic floating body outlet novel energy dissipation, has the advantages of deflecting flow, face flow and bottom flow, and is applicable to any topographic and geologic condition. The dam over-standard flood diversion siphon belt is simple in structure, fast to build and low in manufacturing and is characterized in that a trash rack (2) is installed on the outer side of an inlet of a siphon body (5), the siphon body (5) is connected with a water injection pipe valve (6), the downstream tail end of the siphon body (5) is provided with a check butterfly valve (8), the outer side of the downstream tail end of the siphon body (5) is connected with a rigid framework artificial synthetic material water conveying belt (9) which is connected with an artificial synthetic material water conveying belt (10), and the tail end of the artificial synthetic material water conveying belt (10) is connected with a dynamic floating body outlet (11). The dam over-standard flood diversion siphon belt is applicable to dike and dam controllable emergency flood diversion and flood-fighting and emergency rescues.

Description

technical field [0001] The invention belongs to the technical field of embankment flood diversion and conservancy engineering, and in particular relates to a siphon belt for flood diversion of superstandard floods of embankments. 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 innovative method to achieve this goal also solves the worldwide problem that the dam exceeds the standard and the flood overflows and bursts, injuring people and destroying property. On September 10, 2015, an embankment breach occurred in Japan, and entire houses and rows of vehicles were washed away, causing many casualties and missing, and a large amount of property loss. The probability of floods, the height of the embankment...
