Recently，A loud rumbling noise came from the Longxing Bridge project in Nanchang, Jiangxi Province.，Several rotary drilling rigs began drilling construction.，This marks that the joint construction project of Yangzizhou Ganjiang Highway and Railway Bridge in Changjiu high-speed railway has formally entered the main construction stage.。

Changjiu high-speed railway starts from Lushan Station in Jiujiang City in the north.，To Hejiacun Line Station of Chang-Gan high-speed railway.，Total length of main line 137.72 kilometers。The ratio of bridge to tunnel of the whole line is 82%，There are 58 bridges.，21 tunnels。

Among，Longxing Bridge, located in Nanchang City, is a common channel for Changjiu high-speed railway and the North Second Ring Road of Nanchang City to cross the Ganjiang River.，It is a high-speed railway.、Urban Expressway、It is a large-span highway and railway bridge integrating three traffic modes of urban trunk roads.。The total length of the bridge is 18.95 kilometers，Including 4 sections jointly constructed by highway and railway.957 kilometers。

  

Sany who participated in the construction of this projectSCC850A-6 Crawler crane，After the hole is drilled by the rotary drilling rig,，Be responsible for lifting and placing the pile casing at the designated hole.，Lay a solid foundation for bridge construction。

After the operation of rotary drilling rig，A large amount of waste slurry, sewage and drilling slag containing mud are produced every day.，In addition, there is rain from time to time in Nanchang.，As a result, the construction site became muddy.。Facing harsh construction environment，SCC850A-The advantage of 6 has been brought into full play.。

SCC850A-6 four-wheel belt equipped with 800mmReinforced track shoes，Walk like walking on the ground，No need to level the road，The adaptability of the site is good。Mass of complete machine 75.5t，Maximum lifting torque 358t·m，And that lif performance is strong。

  

Operator Xiong Shifu said.：“This car is very comfortable to use.，Very stable to operate，Slewing performance is also good.。I have been driving the Sany car for the past few years.，The project side has a high degree of recognition.，Now there are more and more Sany equipment involved in the construction of major projects in Jiangxi.。It is believed that the red arm of Sany will continue to be erected in the major projects of Jiangxi Province in the future.。”

  

It is understood that，Longxing Bridge in Nanchang, Jiangxi The upper layer of Longxing Bridge is an urban expressway with a design speed of 80 kilometers per hour.，The lower layer is a double-track railway plus a two-way four-lane urban trunk road.。

Liu Jun, Director of North Second Ring Project Office of Nanchang Construction and Investment Group, introduced.：“As far as we know, this structure，It is also a relatively advanced structure in China.。It saves the passage across the river.，But also save that construction cost of the project.，At the same time, it can also play a very good economic benefit.。” Longxing Bridge to Improve the Construction of Nanchang high-speed railway Hub，It is of great significance to build a comprehensive transportation hub with important national influence.。
