The main bridge is 1156 meters long; the bridge deck is a two-way four lane urban expressway with a design speed of 60 km / h; the total investment of the project is 18 million yuan.

Construction process

In May 1971, the former Ministry of communications of the people's Republic of China approved the former Changsha Municipal People's government to build a bridge between Yuelu District and Furong district in Juzizhou; on September 6, the construction of Juzizhou bridge was started, which was called "Changsha Xiangjiang bridge".

In March 1972, the construction team built 18 piers of Juzizhou bridge; on September 30 of the same year, the bridge was completed and the opening ceremony was held.

Since May 17, 2006, Changsha road and Bridge levy maintenance management office has carried out partial repair on the bridge deck of Juzizhou bridge, excavated, filled and compacted the damaged pavement, and repaved the bottom and surface layers with oil. In the same year, in order to reflect the characteristics of Changsha, the first Xiangjiang Bridge was renamed as Juzizhou bridge.

In January 2006, the original Xiangjiang River Bridge was renamed as Juzizhou bridge

.

From July to August 20, 2008, the minor repair and reconstruction project of Juzizhou bridge was carried out.

In March 2011, the New South Branch of Juzizhou bridge was put into operation.

On July 23, 2013, the pavement of Juzizhou bridge was renovated.

On August 5, 2018, the quality improvement and reconstruction of Juzizhou bridge was carried out; from September 1 to 30 of the same year, the sidewalks on the north and south sides of Juzizhou bridge were semi closed in stages, the pavement of sidewalks and the repair and coating of railings were carried out, the drainage system of sidewalks and bridge deck were transformed, and the conventional diseases of the bridge were repaired.

Bridge location

Juzizhou bridge is located at Wuyi Avenue in Changsha City, Hunan Province, China. It starts from the intersection of Jinxing road and Fenglin Road in the west, crosses Xiangjiang waterway and Juzizhou, and ends at the intersection of Furong Middle Road and Wuyi Avenue in the north.

Architectural design

building structure

Overall layout

Juzizhou bridge is composed of main bridge on water, approach bridge in Yuelu District on land, approach bridge in Juzizhou District, approach bridge in Furong district, pier, arch rib and interchange ramp. The main bridge section is arranged from due west to due east.

 

Design concept

Juzizhou bridge adopts the most popular double curved arch bridge construction form at that time. The reason why the double curved arch bridge was popular at that time is that the national economy of China decided that expensive bridges could not be built everywhere. The construction of double curved arch bridge has the advantages of short construction period, convenient construction, low cost and strong bearing capacity, which is suitable for the national conditions of China at that time Therefore, the double curved arch bridge has been widely promoted in China, becoming one of the largest highway double curved arch bridges in China.

 

Design features

The superstructure of the main bridge and the branch bridge of Juzizhou bridge are reinforced concrete double curvature arch without hinge and double hinge respectively.

 

The main bridge adopts three types of foundations, i.e. steel rice pile cofferdam expansion foundation, soil cofferdam open cut expansion foundation and open caisson foundation; five piers of East bank approach bridge adopt bored pile foundation and open caisson pile foundation respectively; the pier foundations of main bridge and approach bridge are directly embedded in rock plates such as red sandstone or calcareous sandy shale; ten piers of Branch Bridge in Orange Island are open caisson foundation . Arch rib adopts convex section, abdominal arch ring adopts reinforced concrete structure, arch wave adopts No. 200 concrete prefabrication, with a small amount of steel mesh welded into it, arch plate adopts wave shaped section, bottom beam, column and capping beam are reinforced concrete structure, bottom beam is reinforced according to structural requirements; road arch of main bridge and supporting deck adopts straight insertion arc type, and waterproof layer adopts two felt and three oil. The arch rib joint is of stepped shape, and the rib seat is of rectangular flat bottom with structural reinforcement.

 

 

Design parameters

The main bridge of Juzizhou bridge has 21 spans, with a total length of 1532m and 1250m The main bridge is 1156m long and (8x76 + 9x50m) long; the east bank approach is 94m long and (18 + 20 + 23 + 27m) long; a 10 hole double curvature arch branch bridge is 282m long and (6x30 + 4X20M) long; the main bridge is 20m wide, including 14m wide carriageway and 3M wide sidewalks on both sides; the branch bridge is 8m wide, including 6m wide carriageway and 6m wide sidewalks on both sides There are 33 piers and abutments in the whole bridge, including 18 main bridges, 5 approach bridges and 10 branch bridges.

 

Operation

Fare system

As of March 2018, no toll system has been implemented for Juzizhou bridge.

 

Traffic matters

As of March 2018, in order to ensure the smooth construction of Juzizhou bridge detection project and the road traffic safety during the construction period, from 0:00 to 6:00 every night from March 10 to March 21, two-way traffic of motor vehicles is prohibited for Juzizhou bridge. The vehicles passing through this section will bypass Xiangjiang Yingpan Road, nanhu road tunnel, yinpenling and Houzishi bridge.

 

traffic flow

As of August 2018, the two-way traffic volume of Juzizhou bridge has reached 5000 to 5200 vehicles per hour during the peak period and 5900 to 6100 vehicles per hour during the peak period.

 

Construction achievements

Technical problems

On September 6, 1971, the construction of Juzizhou bridge was limited to objective conditions, with poor economic foundation and low degree of mechanization. The construction of Juzizhou bridge was carried out by the designers through a sea of people tactics and voluntary labor, which took a whole year. Before and after 800000 people participated in the construction of the bridge, the construction of Juzizhou bridge was completed.

 

Honorary recognition

Cultural characteristics

In 1978, the former China stamp Corporation issued a special stamp sheetlet T31 - "highway arch bridge Changsha Xiangjiang bridge" for Juzizhou bridge.

 

 

In 2017, Juzizhou bridge was selected as the third batch of historical buildings in Changsha.

 

Value significance

After the completion of the Juzizhou bridge, it has played a great role in adapting the situation of the east-west division of the North Xiangjiang River in Changsha, connecting the traffic between the East and the west of Hunan, and developing the urban and rural economy. < I (review of the first academic conference on urban bridges of Municipal Engineering Committee of Chinese society of Civil Engineering) < / I
