Words describing footbridges

1. About the composition of the footbridge Along the bustling crowd, I saw the tricolor indicator light embedded in the middle of the overpass beam working tirelessly in the distance. The beige overpass gives people a harmonious and elegant feeling. Walking on the stairs with orange handrails on both sides, a soft sense of Shu Yue arises spontaneously. The steps are made of red cylindrical bricks, and there is a green strip on both sides to connect them up and down, making them seamless. In the middle of the ladder is a low platform that is not too wide. At the corner, if you don't go up, you can turn to another nearby staircase. If you continue to climb more than ten steps, you can reach the corridor. Careful people will find that there is a hollow strip covered with a net on the side wall, and there are rows of colored lamp holders inside. I seem to see the overpass on holiday night: colorful, flashing lights, emitting charming brilliance. ...

Standing on the overpass, my vision suddenly widened. It is about two stories above the ground, and you can get a panoramic view of the busy "true face" of Dongjiekou Scenic Resort scenic spot: the whole Yaoqiao Bridge is a slightly round square around the intersection, with the wide Bayi-Qiqi North Road in the north-south direction, Yangqiao Road in the west and East Street, surrounded by department stores, post and telecommunications buildings, Xinhua Bookstore and ice halls. The pedestrians along the road are orderly, and the conductor in the street center is in the center under the bridge. The flashing traffic lights are like the eyes of the city and the wonders of the overpass. At this moment, it suddenly occurred to me, why didn't such a huge suspended steel frame see the column? I looked down along the steel frame of the bridge and the mystery was solved. It turns out that there is a V-shaped bracket like a petrel spreading its wings between the two stairs next to each road, and there is a pillar with a diameter of about half a meter on each side of the bracket. There is also a round thick steel pipe.

Some pillars are located in that inconspicuous place and quietly extend to the ground. In my opinion, the designer's goal is to reduce people's sense of depression without obstructing their vision at the bottom of the bridge. However, designers are still not satisfied. Gorgeous three-masted lights are installed on the stairs and the top porch of the overpass, and the red lampposts set off the milky light group, giving people unlimited joy. On the passage between the stairs, there is an unusual four-masted lamp-these lamps complement each other and echo each other, just like clusters of fragrant magnolia flowers. Gardeners also fully demonstrated their talents. Next to each group of columns, flower beds were built with colorful flowers and decorative trees, which played the role of "icing on the cake". The sidewalk of the overpass is surrounded by railings, which protects motor vehicles and bicycles from people. Facing this beautiful street view, every pedestrian must want to climb the bridge to enjoy the prosperity of the city. When I got off the overpass, it was far away from it, but when I looked back, about three colors of lights on the bridge were still flashing magically at me. What are they trying to say? Do you want to talk about the sacred sense of responsibility in your work, or do you want to talk about the greater changes in Rongcheng in the future?

2. The sentences describing the overpass are simple and beautiful. Cars of all sizes and shapes are driving in an orderly way, and people are coming and going. Whenever a beautiful and quiet night comes, in an instant, the sound of cars, voices and street lights ignite the passionate flame of Xinyu and break the tranquility of the night sky. It constitutes a harmonious and beautiful picture. A series of clever and vivid statues stand on the sidewalk of the overpass. Some of them depict the unique beauty of handicrafts, some show the graceful posture of elegant and beautiful goddess, some depict the vigorous posture of heroic youth, and some are full of the fragrance of loving parents for their lovely children ... one knife at a time, I can hardly imagine the makers.

5.2. 1 When street trees, bus stops, bus shelters, telephone booths and other facilities are set along the sidewalk, the normal traffic of pedestrians shall not be hindered.

5.2.2 When determining the capacity of sidewalks, it should be calculated according to the actual net width of the passable pedestrian walkway. 5.2.3 The width of the sidewalk shall be calculated according to the multiple of the pedestrian zone, and the minimum width shall not be less than1.5m. The width and capacity of the pedestrian zone shall comply with the provisions in Table 5.2.3.

5.2.7 The design of footbridges or tunnels shall meet the requirements of urban landscape and be closely integrated with nearby above-ground or underground buildings; At the entrance and exit of pedestrian bridge or tunnel, the land for the distribution of people should be planned, and its area should not be less than 50m2.

5.2.8 In cities with frequent earthquakes, tunnels should be used for pedestrian crossing facilities.

4. The description of footbridges is more than 600 words, which is a general term for all kinds of footbridges. In fact, according to different functions, it can be divided into "pedestrian overpass", "vehicle overpass", overpass with mixed traffic and "overpass viaduct" which constitutes the urban elevated road system.

With the rapid development of science and technology and industrial production, the structure of overpass is constantly developing and changing. At present, there are many types of overpasses, such as beam overpasses, steel frame overpasses, suspended cable overpasses and cable-stayed overpasses. Some of them are simple in structure and easy to build; Some are full of changes and various forms; Some of them are flying in the air, which is very spectacular ... forming a three-dimensional picture of rainbow racing cars in modern urban traffic.

Overbridges are more diverse in shape and style. Generally speaking, there are many kinds of footbridges, such as one-shaped, T-shaped, cross-shaped, S-shaped, Y-shaped and U-shaped. All these are amorphous and flexibly designed according to the terrain. The basic types of overpass are diamond, alfalfa, ring and trumpet. In short, as long as the use function, structure and appearance are perfectly combined, good artistic and technical effects can be achieved.

Overpass in the city is not only a symbol of urban prosperity, but also plays a great role in urban transportation, energy and efficiency. Taking the pedestrian overpass on Yan 'an East Road in Shanghai as an example, after the opening of the overpass, the speed of motor vehicles in the vicinity of the overpass 100 meters is 28% higher than that before the opening, while the traffic accidents are reduced by 80%, which has obvious economic and social benefits. Since the first overpass was built in 1964 Guangzhou, thousands of overpasses have been built in China and other large and medium-sized cities, which have played a great role in urban traffic, energy and efficiency.

With the continuous progress of science and technology, the development prospect of overpass is broad. The overpass in the future will be a three-dimensional comprehensive structure, which will connect high-rise buildings of different levels in the whole area. People can walk from one store to another, from home to hospitals, schools and office buildings, or visit relatives and friends, or participate in various social activities and entertainment activities.

5. The sun shines on that path through the treetops ... I'm here again ... This is the overpass from Fengze Street to Daping Mountain. This overpass is so big! Its main span is 495 meters high, 55 meters above the ground and 43 meters wide! The pier is made of steel, and the bridge deck is covered with a thick layer of cement.

From a distance, it is magnificent, just like a steel giant! From a distance, there are yellow bricks and red turns on the bridge, which is really beautiful. Looking down from the bridge, there are really many vehicles!

As I remember, this bridge was built in 20 12 1 1 year. Before that, my sister and I often played by the bridge. When we are bored, we will play with sand and jump under the bridge ... It's interesting to think about it now!

Before this overpass, the traffic on the road was very chaotic, and people were crossing the road. I think this is very dangerous. However, since this overpass was built, it is much safer for people to walk on it. This overpass extends in all directions, with 7 pedestrian walkways, 4 of which can allow non-motor vehicles to drive!

In the evening, my grandfather and I were blowing a cool breeze on the overpass. Really comfortable!
