Introduction about bridges, introduction about bridges, introduction of various bridges

1. People walk on the bridge, and the water flows under the bridge. The people on the bridge used the bridge as a road and stepped on it. Man is always like this, thinking that he is the primate of all things and has the right to stop anything; The water flowing under the bridge regarded the bridge as a weakling, and it was a mockery, and the laughing bridge could not stop its raging waves.

2. The bridge body spans both sides of the river, like a flying rainbow. 3. It is a stone arch bridge with an advanced ageStraddling the Xin'an River with a low chant and singing. The water is beautiful, the river is beautiful, the bridge is also beautiful, and the bluestone road on the bridge is polished by the footsteps of pedestrians.

The years are like a filtered screen, sifting away the soil in memory, leaving behind the glittering gold. I have long admired the simplicity of the Zhaozhou Bridge and the majesty of the Yangtze River Bridge. However, I always think about the small bridge in the ancient city of my hometown, and the small bridge that I dreamed of in my childhood.

When it comes to the holidays, the wisps of concern always prompt me to look for the warm and sweet childhood memories.

Introduction to the bridge:

A bridge is a large structure used to cross obstacles. Specifically, it is a structure used to cross transportation routes (such as roads, railways, waterways, etc.) or other facilities (such as pipelines, cables, etc.) over natural obstacles (such as rivers, straits, canyons, etc.) or artificial obstacles (highways, railway lines).

Presentation about the various bridges:

1.Lugou Bridge, also known as Lugou Bridge, is located in Yongding River, Fengtai District, Beijing, named after crossing the Lugou River (i.e., Yongding River), and is the oldest existing stone-built arch bridge in Beijing.

2.Zhaozhou Bridge (Zhaozhou Bridge), also known as Anji Bridge, commonly known as the Big Stone Bridge, is a stone arch bridge across the Hu River in Zhao County, Shijiazhuang City, Hebei Province, China, built by Li Chun, a craftsman of the Sui Dynasty, and is the world's oldest existing single-hole open-shoulder stone arch bridge with the largest span and the most complete preservation. The Zhaozhou Bridge was built from the fifteenth year of Emperor Kaihuang of Sui to the first year of Sui Daye (AD 595-605).

3.Guangji Bridge, namely Chaozhou Guangji Bridge, known as Kangji Bridge, Dinghou Bridge, Jichuan Bridge in ancient times, commonly known as Xiangzi Bridge, also known as Chaozhou Xiangzi Bridge, is located outside the east gate of the ancient city of Chaozhou City, Guangdong Province, across the Hanjiang River, connecting the east and west banks, integrating beam bridges, pontoon bridges, arch bridges, and ancient Guangdong to Fujian and Zhejiang transportation points, is one of the eight scenic spots of Chaozhou, is a famous cultural relics tourist attraction in Chaoshan area, one of the four ancient bridges in China, a national key cultural relics protection unit, a national AAAA-level scenic spot, and is praised by the bridge expert Mao Yisheng The world's first hoisting bridge".

4.Luoyang Bridge (Luoyang Bridge), formerly known as "Wan'an Bridge", is a bridge connecting Taiwanese investment zone and Luojiang District in Quanzhou City, Fujian Province, China, located on the Luoyang River waterway, and is also a famous cross-sea beam type large stone bridge, known as the "first bridge in the sea", is one of the "four famous bridges" in ancient times.

1. A bridge is a large structure used to cross obstacles. Specifically, it is a structure used to cross a natural obstacle (such as a river, a strait, a canyon, etc.) or an artificial obstacle (a highway, a railway line) between a transportation route (such as a road, railway, waterway, etc.) or other facilities (such as pipelines, cables, etc.). The purpose of a bridge is to allow people, vehicles, trains, or ships to pass through the barrier.

2. The bridge can be built on both sides of the river valley or the sea bend high gorge, or it can rise from the ground and bury the foot high, cross the river or road below, and let the traffic below flow unimpeded. The "bridge" was originally a tall tree (see arbor), because it was tall enough to be cut down and placed long enough on the surface of the river, and could be connected to two banks, that is, a single-plank bridge.

1. The bridge is an overhead man-made channel. It is composed of three parts: superstructure, substructure and foundation. The superstructure includes the bridge body and deck; The substructure comprises piers, abutments; The foundation is composed of open-cut foundation, pile foundation, caisson foundation, caisson foundation, string foundation and cushion cap.

2. Main function: that is, to solve the traffic across the water or the development of the valley crossing, so as to facilitate the smooth flow of transport vehicles or pedestrians on the bridge. In terms of its earliest or most important function, the bridge should refer specifically to the road that crosses the water.

Therefore, the annotation of the jade cut in the text explanation field is: "The word of the beam, with wood across the water, the bridge of today is also." It explains that the original meaning of the bridge refers to the passage of wood on the water, and later it is extended to the "plank road" erected on the cliff and the "flying pavilion" erected between the pavilions and palaces.

Modern bridges also play an important role in urban traffic, and the flat ground bridge (overpass) connects the east, west, north and south, which not only helps to alleviate traffic congestion, but also becomes a beautiful scenery in modern cities. China is the hometown of bridges, and has been known as the "country of bridges" since ancient times, developed in the Sui Dynasty.

The bridge is an overhead man-made passage, which consists of three parts: the superstructure, the substructure and the foundation. The superstructure comprises the bridge body and the bridge deck, and the substructure comprises the pier and the abutment, and the foundation is composed of an open-cut foundation, a pile foundation, a caisson foundation, a caisson foundation, a pipe string foundation and a cushion cap.

A bridge is a large-scale structure used to cross an obstacle, which is a structure that crosses a natural or artificial obstacle for a transportation route or other facility to allow a person, vehicle, train, or ship to cross the obstacle.

Bridges are divided according to the stress characteristics, there are five basic types of beam bridges, arch bridges, rigid frame bridges, suspension bridges, and composite system bridges, and the bridges are generally built in a large span and shallow waters, and are composed of bridge columns and bridge plates.

Arch bridges are generally built on water with smaller spans, and the bridge body is arched, and there are generally several bridge holes that play the function of flood discharge, and the weight in the middle of the bridge is transmitted to both ends of the bridge, and the weight of the two ends is transmitted to the middle.
