Rain curtain generating and dust fall rain curtain pipe device suitable for high-steep canyon construction area

Abstract

The invention discloses a rain curtain generating and dust fall rain curtain pipe device suitable for a high-steep canyon construction area; the device comprises a dust fall rain curtain pipe and a dust fall monitoring system, wherein the dust fall monitoring system is used for controlling the dust fall of the dust fall rain curtain pipe; the dust fall rain curtain pipe comprises a main water pipe, a rain curtain pipe and steel ropes; the two ends of the steel ropes are fixed on the two sides of the canyon by the anchoring ends of the steel ropes in equal distance; the lower parts of the steelropes are provided with the rain curtain pipes through rain curtain fixing rings; the steel ropes and the rain curtain pipes are arranged in parallel up and down; one ends of the rain curtain pipes communicate with a main water pipe; a plurality of water spray holes are formed in the two sides of the rain curtain pipes; the device further comprises a pressure pump, which is arranged on the main water pipe; meanwhile, the arrangement form of the rain curtain pipes is provided by the distance of the rain curtain pipe, the arrangement height of the rain curtain pipes and the relationship betweenthe gravity and wind power; the comprehensive coverage of the open cut area of a hydropower station is realized; the limitations of insufficient open cut and dust fall coverage and poor effect of theexisting hydropower station are effectively solved, and the effects of high efficiency, energy saving, water saving and dust fall are achieved.

Description

technical field [0001] The invention relates to the field of dust reduction, in particular to a rain screen generation and dust reduction rain screen tube device suitable for high and steep canyon construction areas. Background technique [0002] At present, the known large-scale hydropower projects are all built in mountainous areas with deep valleys and high and steep valley slopes. A large amount of dust will be generated during blasting and excavation with high and steep heights and large spans. The traditional dust control method is basically to manually observe the size of the dust on the construction site. , the use of high-pressure water guns, air-driven sprayers, etc. for manual watering and dust reduction has large limitations and a small effective watering area, which consumes a lot of manpower and material resources. The coverage of dust control is very limited, the accuracy and reliability are low, and the effect is difficult to achieve. It directly affects the ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a rain screen generation and dust-reducing rain screen tube device suitable for high and steep canyon construction areas, and also provide a rain screen tube arrangement, through the distance between the rain screen tubes, the rain screen tube Arrange according to the relationship between the layout height, gravity and wind force, and use the least material and the most convenient way to achieve full coverage of the open-cut area of ​​the hydropower station, effectively solving the limitations of insufficient coverage and poor effect of open-cut dust reduction in existing hydropower stations. Realize high efficiency, energy saving, water saving and dust reduction, and greatly reduce the cost of dust reduction; at the same time, through the combination with the intelligent control device, the problems of high manpower and material cost and difficult management of the existing dust reduction device are solved, and the impact of dust on the project is resolved. The impact on the health of builders and surrounding residents, significant economic value and outstanding social benefits
