Wang Bo, the fourth master of the early Tang Dynasty, wrote: "It is difficult to cross the mountain, and those who are sad to lose their way; when Pingshui meets, they are all guests of his hometown." "Would he have thought that on September 25, 2021, a thousand years later, the 9,650-meter-long tunnel under Guanshan mountain was opened for trial operation, marking the full opening of the Pingliang-Tianshui Expressway with an estimated total investment of 22.5 billion yuan and a total length of 168 kilometers, and Guanshan was crossed!
Refuse fatigue and start with a light show
Continue along the Pingtian Expressway, and the beautiful Guanshan scroll slowly unfolds. Although the Guanshan Tunnel, which is nearly 10 kilometers long, temporarily separates the beauty of Guanshan, there is a beautiful light show waiting for people on the journey. Considering that the space in the tunnel is relatively small, the environment is depressing, the depth is long, the closure is strong, and the driver is prone to visual fatigue and psychological panic, the changing light show at the top of the tunnel has become a necessary move to alleviate visual fatigue and increase driving pleasure and comfort.
The scenery of the four seasons, all in one place
Blue sky, white clouds, galloping horses, the tunnel above the presented an open world, as if in the grassland, the mind suddenly opened up, the fatigue of driving was also dissipated. Immediately after, the verdant spring is dripping, the summer is as warm as fire, the autumn is enthusiastic, the winter is wrapped in silver, and the beauty of the four seasons is in full view, which is mesmerizing. Further ahead, a full moon hangs above the sky, lonely travelers, with the moon as a companion, look at the moon, miss the hometown, ancient and modern, only this moon, staring at the earth, but also staring at every wandering guest.
At the end of the Guanshan Tunnel, the vast universe quietly awaits the arrival of travelers, it is silent and huge, silent and far-reaching, wandering in countless stars, there is a sense of loneliness that "after drunkenness, the sky is in the water, full of boats and dreams press the galaxy", which makes people wake up like a big dream, and the aftertaste is endless.
Considering that the National Day is approaching, the tunnel specially adds a lantern belt with the theme of flying national flag and party flag, which symbolizes that under the leadership of the Communist Party of China, the people will have a stable and happy life and an infinite yearning for a better tomorrow.
Aike helps the tunnel with a beautiful light show
In the project, Aike adopted an intelligent dynamic vision system, consisting of nearly 20,000 EXC-P22GP point light sources and more than 110,000 EXC-P28GP point light sources, interspersed with spacing installation, with points into lines, from lines into surfaces, forming a neat and orderly array of lamp beads at the top of the tunnel arch. Both point light sources are RGB full-color LEDs, which are observed and regulated by the Aike intelligent cloud control platform to achieve colorful, dynamic and static combination, adjustable and interchangeable graphics, images and text light and shadow effects, presenting a lifelike and beautiful scenery.
Safe, energy-efficient and economical green lighting is a principle that Aike has always followed, and the Guanshan Tunnel project is no exception. When choosing a point light source, considering portability, practicality, safety and environmental protection, Aike finally chose the EXC-P28GP point light source and EXC-P22GP point light source with the above characteristics. High color temperature expressiveness and high color rendering add a lot of color to the two point light sources, and at the same time, the luminous flux of nearly 20,000 lumens can be emitted in an area of 250 square meters, which is equivalent to the brightness emitted by traditional 250-watt halogenated bulbs, and this superiority also makes the two point light sources destined to become the first choice for this project.
Design principles
1. Functional principles
Meet the two indicators of "visual function" and "visual comfort" to ensure driving safety
2. Aesthetic principle
Shape, color, artistic interest
3. The principle of economy
Practical value + appreciation value
4. Security Principles
Anti-electric shock, anti-short circuit, anti-glare, waterproof
Aike intelligent cloud control platform
Looking at the current situation of domestic tunnel landscape construction, there are generally problems such as single effect, high maintenance costs in the later stage, limited technology, etc. Aike designs and uses exc-GP series point light source + intelligent cloud control integrated platform + intelligent strong and weak power control equipment, using the Internet of Things, big data, cloud computing and other technologies, and provides a clear and clear graphical interface of data statistics, visual GIS electronic map interface and other forms of visual interface, greatly improving the level of intelligent management of the entire project. EXC-GP series point light source 50000-100000h long life characteristics, greatly reducing maintenance costs.
The sea of stars never stops
The Pingtian Expressway, which connects the two sister cities of Pingliang and Tianshui, is not only a major project for the benefit of the people, but also a new popular attraction because of the unique light show of the Guanshan Tunnel!
