A fully enclosed transparent shed tunnel in the flood discharge atomization area of ​​a power station

Abstract

This invention discloses a fully enclosed transparent canopy for the flood discharge atomization zone of a power station. It comprises walls connected to the mountain slope, a load-bearing frame, and a light-transmitting panel. The load-bearing frame is connected to the walls to form a fully enclosed canopy structure. This structure can prevent damage from heavy rainfall, wind loads, and the air pressure characteristics of the atomization zone. The light-transmitting panel is fixed through the load-bearing frame. Using a light-transmitting panel saves the cost of additional lighting facilities while creating an enclosed space. Furthermore, the difference between the light inside and outside the canopy is minimal, and the spectacular flood discharge can be enjoyed from inside. The composite fixing connection method between the load-bearing frames saves materials, reduces construction difficulty, and lowers project costs.

Description

Technical Field

[0001] The invention relates to the technical field of power station engineering, and in particular to a fully enclosed transparent shed tunnel in a flood discharge atomization area of ​​a power station. Background Art

[0002] Flood discharge atomization refers to an unnatural heavy rainfall process and water mist diffusion phenomenon caused by the discharge of water from a discharge structure. Flood discharge atomization produces large-scale, high-intensity atomized rainfall, and the air humidity and temperature in the atomization affected area change significantly, interfering with traffic operations in the atomization affected area. In particular, high-dam and large-reservoir water conservancy and hydropower projects have large flood discharge flows and large flood discharge powers, and the downstream flood discharge atomization problem is prominent. When flood discharge structures discharge flood, there are large-scale strong splashing areas and high-intensity atomized rainfall areas in the flood discharge atomization area. Highways within the range of heavy rain with a heavy rainfall intensity exceeding 50mm / h need to be subject to traffic control or even traffic interruption to avoid traffic safety accidents.

[0003] Further exploration and optimization of the structure adopted in the flood discharge atomization area of ​​a power station so that it has better performance when serving the field of power station engineering technology is a technical problem that needs to be solved urgently by those skilled in the art.

Although the reinforced concrete protective shed cave has strong protection capabilities, its protection efficiency is not high for areas without slope geological disasters, and its economic efficiency is poor. In addition, the landscape effect is poor, which affects the overall landscape effect of the power station.
