Dam exceeding-standard flood diversion siphon frieze group

Abstract

The invention discloses a dam exceeding-standard flood diversion siphon frieze group and belongs to the technical field of dam flood diversion hydraulic engineering. The siphon frieze group can disperse and bleed the exceeding-standard flood to farmland directly to protect the dam and is simple in structure, convenient to finalize, design, produce and transport, convenient and fast to construct, and low in cost. The siphon frieze group comprises a trash rack (2) arranged at the outside of an inlet of a siphon body (5); the siphon body (5) is connected with a water input tube belt valve (6); the tail end of the siphon body (5) is provided with a water output belt clamp valve (8); the water output belt clamp valve (8) is connected with a water output belt (9) made of a rigid body framework artificial synthetic material; an outlet of the water output belt (9) made of the rigid body framework artificial synthetic material is arranged above an apron (10-2) made of an artificial synthetic material; the downstream of the apron (10-2) made of the artificial synthetic material is connected with a rope net pile sandbag baffle sill (11); and the downstream of the rope net pile sandbag baffle sill (11) is connected with an apron extension (10-3) made of an artificial synthetic material. The siphon frieze group is suitable for controllable flood diversion of exceeding-standard floods for dikes, dams and auxiliary dams and dam flood diversion and rescue.

Description

technical field [0001] The invention belongs to the technical field of embankment flood diversion and conservancy engineering, and in particular relates to a dam superstandard flood diversion siphon belt group. 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 in the flood control plan. If innovative theories, 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 flood...

AI Technical Summary

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
