It is a prestressed continuous steel truss structure. The length of the main bridge is 419.6m, with four spans, two spans in the middle112m, and two spans on both sides are 96m. The bridge deck width of the upper highway is 12m, in which the carriageway is 9m wide, the approach bridges at both ends are 1440m long, and there are 22 holes on the north and south banks, with a span of 32.7m. The approach bridges at both ends of the lower railway bridge are 2628m long, with a bridge deck width of12m, 38 holes on the south bank and 42 holes on the north bank, with a span of 32.7m.. There is also the Songpu Bridge in Harbin.

Brief introduction of bridge

The completion of Songpu Bridge has rewritten the history of no bridge in Huangpu River. 199 1, 1993, 1995, 1997, in 2003 and 2005, nanpu bridge, Yangpu Bridge, Feng Pu Bridge and Xupu Bridge were successively built in Shanghai.

Songpu Bridge, the first bridge on Huangpu River, is the key project of Jinshan Branch Line leading to Shanghai Petrochemical Complex. The bridge is located in the southwest of Shanghai suburb, near Desheng Port, Chedun Town, Songjiang District, 7km upstream of Minhang Xi Du 12.5km downstream of Mishidu. The center mileage of the bridge is K5+395.8 of Jinshan branch line, with two-lane highway on the upper floor and single-track railway on the lower floor.

highway bridge

The road surface of the highway bridge is 9 meters wide, and there are 1.5 meters sidewalks on both sides. There are 22 holes on the north and south banks of the highway approach bridge, and 3 1.7m prestressed reinforced concrete simply supported beams are adopted. The length of main bridge is 419.6m, the length of approach bridge is1438.85m, and the total length is1858.45m.. The slope of the approach bridge is 3%. The load is calculated according to the design of steam -20 and trailer-100, and the crowd load is 350kg per square meter.

railway bridge

There are 85 piers in the railway bridge, 3 piers in the main bridge and 1 abutment on both sides. The beam span is a four-hole (96+65,438+065,438+02+65,438+065,438+065,438+02+96m) flat chord outrigger triangular steel truss with a beam height of 65,448. The 42-hole approach bridge on the north bank and the 38-hole approach bridge on the south bank adopt 3 1.7m prestressed reinforced concrete simply supported beams. The railway load is designed according to the medium -22 grade (the freight car is changed from 6.0 tons/m to 8.0 tons/m), and the electric locomotive is not considered. The main railway bridge is 4 19.6 meters long, the approach bridge is 2,628 meters long and the total length is 3,047.6 meters.

Bridge main body

The main project of the bridge was designed by the Survey and Design Department of the Bridge Bureau of the Ministry of Railways, and other supporting projects were designed by Shanghai Industrial Design Institute, Shanghai Civil Design Institute, Shanghai Municipal Design Institute and Shanghai Railway Bureau Infrastructure Headquarters. The main project of the bridge is mainly constructed by the Third Engineering Team of the Bridge Bureau, and the three underwater piers are constructed by the Second Engineering Office of the Third Navigation Engineering Bureau of the Ministry of Communications. The supporting projects are undertaken by Shanghai Construction Bureau, Shanghai Urban Construction Bureau, Shanghai Railway Bureau and Shanghai Power Supply Bureau. Steel truss girder is manufactured by Shanhaiguan Bridge Factory; Prestressed reinforced concrete beams and reinforced concrete pipe piles are produced by Nanjing Bridge Factory of Bridge Bureau. 1.2m steel pipe pile is manufactured by Shanghai Donghai Shipyard and 4805 Factory. Bridge bearings are manufactured by Shanghai Electric Machine Factory, Steam Turbine Factory, Heavy Machinery Factory, Machine Repair Factory and Dalong Machine Factory.

The bridge can be opened to traffic

The bridge started on July 26th 1974, the railway bridge was opened to traffic on September 26th 1 1, and the highway bridge was opened to traffic on June 29th 1976.

According to1July 4th, 973, Nanjing Earthquake Brigade of State Seismological Bureau provided the Appraisal Report of Basic Earthquake Intensity in Shanghai Petrochemical Complex Area, it was determined that the basic earthquake intensity in the area of Shanghai Petrochemical Complex was 5 degrees. The bridge site is located in Songjiang County, near Jinshan County, with a basic intensity of 6 degrees.

Completion handover

1977165438+10 The Huangpu River Bridge acceptance handover team was established in Shanghai. In the acceptance handover report, the team believes that the construction method of using large steel pipe pile cap and hanging box cofferdam to build pier and abutment in the bridge design is advanced, and the maintenance needs are fully considered. The main project of the bridge has high construction quality and high speed. The estimated budget of the whole bridge is 52.58 million yuan, and the actual cost is 494 1.56 million yuan.

1 977 65438+February1officially taken over by Huangpu River Bridge Management Office of Shanghai Railway Branch. The upper highway is maintained and managed by Songjiang County Highway Management Office. In order to speed up the infrastructure construction in Shanghai, with the approval of the municipal government, the motor vehicle toll of Songpu Bridge is levied from 1987 1, and the Songpu Bridge Collection Station of Songjiang County Highway Management Office of the Municipal Highway Department is responsible for the collection and management. This is the first bridge in Shanghai to collect tolls. By the end of 1995, the accumulated toll of vehicles crossing the bridge was 202 million yuan.
