I want the detailed history of Liuzhou Liujiang Bridge.

History of bridge construction: it took 26 years to build the bridge, 1, 942, 1. At that time, Liuzhou City Construction Committee set up a bridge engineering office to prepare for the bridge construction, sold all public landmarks in the city to raise funds, and hired Guangxi Bridge Exploration Team to survey, but it failed to be implemented for various reasons.

1958, the municipal party Committee called on the people of the whole city to carry out social sponsorship activities such as donations and raise donations of more than 2 million yuan. Subsequently, the preparation office of Liuzhou Bridge was established, and the construction was carried out according to the bridge type scheme of continuous steel truss structure. 1959, two underwater double-column piers were built to produce water, but they were stopped because 3700 tons of large imported steel could not be solved.

In the following five years, the relevant design units designed several bridge schemes, which were not adopted due to the poor geology of the middle pier. "1960, Soviet experts came to see it, saying that if you want to build a bridge on the Liujiang River, you have to invite Polish geological experts and Hungarian suspension experts."

From 65438 to 0963, the bridge was designed by Shanghai Municipal Engineering Design Institute and presided over by Mr. Lin Yuanpei, a famous bridge designer in China. Liu, then deputy chief engineer of the Municipal Academy, served as the chief designer of Liujiang Bridge.

1964 65438+In February, the State Planning Commission and the Ministry of Construction approved the construction of a prestressed concrete T-cantilever bridge with suspended beams with a span of 120m on the original bridge site. The Shanghai Foundation Company, which participated in the construction, undertook the construction of the underwater part and the main pier, the fifth company undertook the construction of the approach bridge, overpass and the whole bridge deck, and Dong was responsible for the construction. The technicians from Liuzhou Municipal Engineering Office participated in the work of the bridge headquarters.

After two years and nine months' efforts, Liujiang Bridge finally flew over Liujiang, connecting the two banks of Liujiang closely and becoming the first cross-river highway bridge in Liuzhou. The bridge was completed in June 1968. To commemorate Mao Zedong's birthday,196865438+announced the completion of the bridge and held a ribbon-cutting ceremony on February 26th.

Bridging data

This bridge is 608.04m long and 20m wide. The main bridge is 408. 19m long and consists of three T-beams and hanging beams, with a maximum span of 124m and a hanging beam length of 25m. The bridge is 20m wide, with double box and double chamber sections and three-dimensional prestressed steel bars. The substructure is reinforced and reconstructed by using the piers of the original 120m steel truss continuous beam bridge. The bridge consumes domestic steel 15 15 tons and cement 608 1 ton, with a cost of 7,275,200 yuan.

honour

Liuzhou Bridge is the first bridge designed by Lin Yuanpei. Its main span is about1.24m, and it is the first T-shaped steel structure bridge in China. It is the first prestressed concrete T-shaped rigid frame bridge built by cantilever casting method in China. At that time, it was the first in China and 13 in the world. The bridge deck is unique in structure and advanced in construction technology, and won the 1978 National Science Conference Award. The completion of this bridge ended Liuzhou's history of using pontoon bridge as a traffic bridge and made great contributions to the development of Liuzhou.
