A plan for a thousand years，Infrastructure Xiongan Future City，Rise from the ground recently，Shanggong Machinery in this world-renowned future new cityTRD-70EThe construction machine relies on its excellent performance.、The efficiency is excellent、Creating high efficiency and setting off market storm again，Hunan Chengji completed the first pile test show、Shanggong Machinery Unites to Help Xiongxin High-speed Railway in Xiongan New Area Jointing Growth in North China Plain for the Construction of Xiongan New Area、Beijing-Tianjin-Hebei coordinated development injection“Acceleration”！
Xiongxin High-speed Railway
At《Planning Outline of Xiongan New Area in Hebei Province》Medium
“Four vertical and two horizontal”Regional High Speed Rail Transportation Network
Important lateral passage
It connects Xiongan New District and Xinzhou City, Shanxi Province.
The most convenient high-speed railway passage
National medium and long-term high-speed railway network planning“Eight vertical and eight horizontal”
It is an important part of the Beijing-Kunming corridor in the main corridor.
Xiongxin High-speed Railway starts from Xiongan Station of Jingxiong Intercity Railway.，Finally arrive at Xinzhou West Railway Station of Daxi High-speed Railway，The total length is about 342.Seven kilometers，The construction of Xiongan New Section bears the construction of the new area.“A plan for a thousand years、A matter of state”A historic task，To further promote the high starting point planning of Xiongan New Area、High level construction、High quality development，Better create demonstration zones for innovation and development、High-end industrial clusters in world-class cities are of great significance.。
▲Project construction site
The participating project is the civil engineering and related supporting projects of the underground section of Xiongan New Area of Xiongxin High-speed Railway.XADXDSG-Lot 2，This bid sectionTRDThe total construction volume of multi-section waterproof curtain diaphragm wall is about 15.40,000 square meters，Before formal construction，Proposed in this bid sectionTRDProcess test section of cement-soil mixing wall:DK120+Segment 950 compartment，TRDCement-soil mixing construction length 22.4m，Wall thickness 80mm，Reinforcement depth 27m，Site leveling elevation of railway tunnel in test section+2m，The current ground elevation is+7m。Project requires wall plane deviation<25mm，Verticality deviation shall not be greater than 1/250，Wall depth、Wall thickness、There shall be no negative deviation in the total length of the wall。

▲TRD-70EConstruction site of construction machine
According to the geological data around the site，The site is mainly Baigou Yinhe River.(Part of the river course adjacent to the tunnel is covered with wasteland、Landfill of farmland and green belt)，The geological conditions are complex，Shanggong MachineryTRD-70EConstruction machine with superior performance，Stable and accurate，Quickly adapt to construction environment，At the advance driving speed of 2m/h，Retreat Digging Speed 8m/h，Mixing speed for wall formation 2.4m/hExcellent construction performance completed the first test pile show.，Completed the test well.。
▲TRD-70EThe drilling machine spudded smoothly
During construction，To maintainTRDLevelness of construction method pile machine chassis and perpendicularity of guide rod，During construction, the inclinometer installed inside the cutting box，Carry out vertical precision management of wall，The verticality of the wall shall not be greater than 1/250，Ensure the quality of the wall。

In the face of the construction site rush to work.，“Three shifts without stopping.”Under difficult conditions.，Shanggong MachineryTRD-70EMethod machine with zero failure，High efficiency，Overcome the tight construction period、The task is heavy、Site constraints and many other difficulties，Hunan Chengjihe“Shanggong Green”Fight hand in hand，Sleep at night，The construction of Xiongxin high-speed railway has been smoothly promoted.。
In addition，It is worth mentioning that，At the construction site of this projectXADXDSG-Within a few kilometers near Bid Section 2, there have been 4 sets of working machines stationed in each construction unit.TRDSeries process machine，Later, more quantities will be stationed one after another.TRDProcess machine equipment，This is the succession again.“Major ecological and livelihood projects in Ganjiang River”And“Pudong Airport Underground Transportation Hub Project”After，Shanggong MachineryTRDSeries of equipment assembled again for construction。At that time，Once again, there will be a scene full of green figures.，Show the responsibility and responsibility of Shanggong Machinery to help the construction of Xiongan New Area，Highlight the century-old national brand style of Shanggong。
