Zhongzhao Lighting Award Lighting Engineering Design Award (outdoor/bridge, road) second prize
Project Name: Xiliuhuan Shishi Road Overpass Bridge, Yong Sculpture Lighting Landscape Construction
Reporting unit: Beijing Hailan Qili Lighting Equipment Installation Engineering Co., Ltd.
The Shishi Road Viaduct starts from Shuangyu Roundabout in Mentougou District in the west and Jinyuan Bridge in West Wuhuan in Shijingshan District in the east. It is an important transportation hub in Shijingshan and Mentougou Districts in the western region. The Yanshi Road Viaduct and the West Sixth Ring Overpass Bridge are integrated into Beijing. Important transportation functions in the western region;
It is an important traffic trunk to enter the capital;
The interaction between the traffic flow and the flow of people is much higher than that of the general traffic trunks, and the demand for visual information and visual comfort is high.
The area of ​​the Shishi Road Viaduct and the West Sixth Ring Overpass is wide, the view is wide, the structure of the bridge is complex, and the overall structure has a sense of layering and space;
The bridge space lighting is mainly functional lighting, no landscape lighting, single lighting method, night scene performance and visual appeal. Compared with the carrier conditions, the night landscape lighting construction has a large room for improvement.
"Chong", the melody of life, the theme of enthusiasm and chorus, the Mentougou, the capital modern modern ecological new area, the modernization of the world city, the green ecological development concept, a new stage, glow Brilliant, full of vitality. The rush, that is, the song of life, the dance of the spirit, the notes that leaps and turns in the city, and dances with the times, the water of life is endless, and the pulse of the times is forever.
Innovations in lighting design concepts, methods, etc.:
The night lighting design of the Shishi Road Viaduct and the West Sixth Ring Overpass highlights the following points:
Cultural orientation
Using the modern design concept, combined with the cultural elements of the historical building of Mentougou, it reflects the nighttime image characteristics of the capital culture;
Image positioning
Reflecting the simplicity, smoothness, modernity and classical beauty of the bridge;
Demonstrate the uniqueness of regional culture;
Improve functional lighting quality and promote night safety and security.
Optimize lighting energy consumption, prevent light pollution, and promote environmental protection and energy conservation.
Symbolic positioning
The door, in the eyes of the Chinese, is the first pass to all places, and it heralds the beginning of everything.
As the first gateway to the capital of the western region, the Shishi Road gives the “national gate†a great atmosphere and displays the unique culture of Jingyun. With the stone road as the center, the door is constructed on both sides of the road, and the door is restored by modern technology. Word intention.
The pattern is a pattern that the folks call "the rich and the rich". It is a square or circular loop pattern formed by winding the horizontal and vertical short lines, and is shaped like a "back", so it is called a back pattern.
The bridge railings are decorated with a retro-styled design that gives a modern feel and a quaint charm.
The lamps use led line lights to outline the back words. In the evening, the pattern of self-illumination forms a pattern of backing and plays a guiding role.

Butterfly valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal, radioactive media and other types of fluids.
The butterfly valve is a kind of regulating valve with simple structure, which can be used for the switching control of medium in low pressure pipeline. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing piece is a disc shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
Common parameters of butterfly valve:
Valve body material: stainless steel, carbon steel, cast iron, alloy
Shape: square, round
Bonnet: customizable
Stem: customizable
Test pressure (MPa): 0.4
Sealing test: 0.275
