After 848 days of construction, Yinchuan Riverside Yellow River Bridge was opened to traffic on April 28th, 20 16. On the eve of opening to traffic, I visited the lighting project of the bridge.
It is understood that the floodlighting project of Binhe Yellow River Bridge is a municipal supporting project of Yinchuan City. The floodlighting project includes the main bridge and overland approach bridge of the Yellow River Bridge on the west side, the overland approach bridge on the east side, the architectural lighting project in service area 6 and the architectural lighting project in service area 9.
The lighting features floodlights to illuminate the bridge belly, and the stay cables, the main tower facade and both sides of the bridge deck are decorated with LED lights. The main lamps are floodlights, LED lamps and other lamps.
The lighting of the bridge needs more than 7,000 LED lights and more than 3,000 light strips. The lights will illuminate six main towers, two main cables, 264 sets of slings and cross-strait approach bridges.
The main bridge is equipped with colorful water curtains, which change back and forth from seven colors, reflecting each other in the night sky, becoming another landmark landscape of Yinchuan, highlighting the urban characteristics of "plugging in the lake city and returning home" and creating a colorful and beautiful city that never sleeps.
This is a large structure for crossing obstacles. Specifically, it is a structure used to cross traffic routes (such as roads, railways, waterways, etc.). ) or natural obstacles (such as rivers, straits, canyons, etc.) on other facilities (such as pipelines and cables). ) or artificial obstacles (highways and railway lines).
The purpose of the bridge is to let people, vehicles, trains or ships pass through obstacles. Bridges can be built in river valleys or on both sides of the Taiwan Strait, or they can rise from the ground and cross the rivers or roads below, so that the traffic below can be unimpeded. ?
The "bridge" was originally a tall tree (see arbor). Because it is high enough and long enough, it can be cut down and put on the river, and it can connect the two banks, so it is a single-plank bridge. Opening and closing bridges give space for big ships to pass through.
A plant grafting method includes inserting one end of one or more scions into the lower part of rootstock and the other end into the upper part of rootstock, separated by cambium or other weak parts, especially for crossing wounds (such as insect bites) to strengthen weak or defective joints.
