Construction method of a multi-angle adjustable deflector energy dissipation device

Abstract

The invention relates to a multi-angle adjustable trajectory bucket type energy dissipation device and a construction method thereof. The multi-angle adjustable trajectory bucket type energy dissipation device is provided with a first-stage trajectory bucket and a second-stage trajectory bucket. The first-stage trajectory bucket is provided with an arc-shaped steel plate, a left steel plate, a right steel plate and a right steel plate, and the left steel plate, the middle steel plate and the right steel plate are arranged at intervals. The second-stage trajectory bucket is provided with adjustment levers. Multi-angle adjustable trajectory bucket type energy dissipation is realized through the adjustment levers, the left steel plate, the middle steel plate and the right steel plate. The energy dissipation effect can be substantially improved. The multi-angle adjustable trajectory bucket type energy dissipation device can be detachably connected through embedded bolts, facilitates structure installation and maintenance and can be extensively applied in new construction or reconstruction projects.

Description

technical field [0001] The invention relates to a deflecting flow energy dissipation device for water conservancy projects, in particular to a multi-angle adjustable deflecting flow energy dissipation device and a construction method thereof. Background technique [0002] In water conservancy projects, in order to realize the energy dissipation of the discharged water, it is often necessary to build energy-dissipating facilities. These energy-dissipating facilities can dissipate and weaken the energy of the water flow by changing the original form of the water flow, so as to reduce the impact of the water flow energy on the downstream river or the existing water flow. Destruction of hydraulic structures and structures. [0003] The deflected flow energy dissipation is to shoot the discharged water into the air through the nose sill or the deflected flow sill, and use the collision generated by the water flow to dissipate the energy in the air. The deflected flow energy dissi...

Problems solved by technology

[0004] In order to achieve deflection dissipation, water conservancy projects also adopt energy dissipation methods such as diffuse deflection energy dissipation and differential deflection energy dissipation. Although these energy dissipation methods are more effective than traditional deflection energy dissipation, the energy dissipation effect is improved , but it is often not adjustable. Once it is built, the deflector will install the set flow channel to dissipate energy, and the damage to the deflector sill will be large. Once the deflector sill is damaged, a large-scale maintenance is required Construction, engineering cost is relatively high
