Urban Construction Double Star Zoomlion Crawler Crane Helps the Construction of the First Diaphragm Wall of Tianjin Metro Line 8

February 21，The first diaphragm wall of Liulitai Station of Tianjin Metro Line 8, which was constructed by the Eighth Bureau of China Construction, was successfully started.，It marks that the station has formally entered the substantive construction stage.。

Tianjin Metro Line 8 is the backbone line in the south of the central city.，Liulitai Station of Line 8 constructed by China Construction Eighth Bureau is a four-storey underground station.，The maximum depth of the foundation pit is about 33 meters.，In addition, there are many surrounding buildings.、Heavy traffic、The environment is complex，It is difficult to control the construction of diaphragm wall and the deformation of foundation pit，It is one of the most difficult subway stations under construction in Tianjin.。

The construction is difficult，The hoisting requirements are high，The two pieces of equipment undertaking this important task are Zoomlion Urban Construction Gemini Star.——ZCC5200SAndZCC5800。ZCC5200SAndZCC5800 are all star products of Zoomlion，With strong hoisting capacity，Features of compact structure，Is particularly suitable for urban construction.。After more than an hour of hoisting operation on site,，Accurate coordination of the two equipment，The steel cage is smoothly inserted into the slot hole，Successfully complete the difficult“Double crane lifting”Task。

“There are 144 diaphragm walls in Liulitai Station of Line 8。The shape of the first diaphragm wall is“One”Font，Reinforcement cage length up to 56.45 meters，Hoisting shall be carried out by means of double-crane lifting.。”The person in charge of the on-site project said.：“Diaphragm wall hoisting is the key construction process of this project.，The way of double-crane lifting is also the difficulty and key point of construction.，With the two equipment of Zoomlion，We have a lot of confidence.。”

ZCC5200SAndZCC5800, the two urban construction twin stars will continue to fight in Tianjin Metro Line 8.，Complete the task of 144 diaphragm walls，Helping Tianjin Rail Transit Construction。
