Construction course of Yumenkou Yellow River Bridge

Yumenkou Yellow River Tiesuo Bridge officially started in March 1949. The first phase of the project is to manufacture components and dig bridge foundation, which are carried out in two ways at the same time. The second phase of the project is to erect iron cables, which is the most difficult stage of the whole project. At the beginning of September, the project was transferred to the third stage for laying and reinforcement. In order to catch up with the bridge test in founding ceremony in June 65438 +654381October +01October, the workers worked day and night, hooked the guardrail at the bottom and both sides of the bridge with barbed wire, paved the bridge deck, and fixed the bridge deck with iron wire. At the end of September, the project was basically completed, and people on both sides of Qin Jin rushed to tell each other, and the People's Voice Pu Troupe (that is, Wang Xiulan Pu Troupe) was invited to perform. 10 1 In the early morning, people who participated in the bridge trial ceremony, beating gongs and drums, came to both sides of the ferry early in the morning. But I never expected that there was a strong wind at night, and all the bridge slabs were overturned into the river, leaving only one piece. Not discouraged, the bridge builders learned from their failures and started a new reinforcement project. /kloc-in the spring of 0/950, the iron cable bridge at Yumenkou was completely completed, and a new bridge, which has never existed since ancient times, crossed Yumen and connected Qin Jin provinces. After the iron cable bridge was officially put into use, thousands of people passed through it every day, carrying up to 800 tons of goods, and no major accidents have ever happened. From the completion of 1950 to the opening of the new highway bridge in 1975, it has played an inestimable role in socialist construction for 25 years. From 65438 to 0975, the bridge engineering team of the Ministry of Railways built a modern flexible steel suspension cable highway bridge and steel truss girder railway bridge on the old basis of railway bridges. In order to keep it as a souvenir, railway bridges, railway bridges and highway bridges cross Yumen side by side for people to watch. Yumenkou railway bridge, highway bridge and railway bridge connect Qin and Jin provinces. Three bridges span the Yellow River side by side, such as three volley rainbows, adding extraordinary momentum to Longmen.

Three bridges stand side by side.

Yumenkou Yellow River Tiesuo Bridge was invested and built by the state in 1949, with a total length of150m and a width of1.5m.. Wooden stakes, iron wires and steel rope railings are laid on the bridge deck, which are laid early and removed late every day, and need to be removed every strong wind. After the bridge deck is paved, pedestrians and villains can pull the animal-drawn cart, and the highway bridge will stop using it after it is completed.

Yumenkou Yellow River Highway Bridge includes 1 suspension bridge and 65438 hyperbolic arch bridge. Construction started in August 1972 and was completed in July 1973. The suspension bridge flies between the Yellow River island and the Shanxi coast; The hyperbolic arch bridge is located between the isolated island in the river and the Shaanxi bank. Both bridges were designed and built by the Bridge Engineering Bureau of the Ministry of Communications. Steam-13, hang a 60. The suspension bridge is a single-span and single-chain suspended cable structure, with tower spacing 144m, carriageway width 7m, sidewalks on both sides 1m, rise-span ratio 1:9, steel tower height 17.93m, stiffening truss support spacing 140m and truss height 3. The ground anchors on both banks adopt reinforced concrete structure, and the cable saddle, cable clamp and anchor head are all made of cast steel. Abutment on both banks are built on rocks. The single-hole double-curved arch bridge has a clear span of 54m, sidewalk width on both sides 1m, rise-span ratio 1: 10, and six rectangular reinforced concrete arch ribs with variable deck, vault thickness 1.24m, arch foot thickness 1.44m, and gentle deck slope. From May 9th, 1974 was handed over to Weinan Highway General Section for maintenance and management.

Yumenkou Huanghe Railway Bridge

Yumenkou Yellow River Railway Bridge is a single-span through steel truss simply supported beam. The Shaanxi side of the bridge is a continuous through prestressed reinforced concrete simply supported beam bridge with more than ten holes. Usually, when the water flow of the Yellow River is small, there is no water under the bridge, and there is also a tunnel at the Shaanxi end of the bridge, which is relatively short. Yumenkou Railway Bridge was built from 197 1 year 65438+February to1April 972, with a total weight of 2100t. Under the conditions at that time, the large scale of the project, the high technical difficulty and the short construction time were all great feats in the history of transportation.
