Recently，Sany Rotary Excavator Group Participates in the Construction of Wuhe Station of Shenzhen Shenzhen-Dalian Intercity Project Bid 2，The project site is assembled.SR415、SR445、SR525ProFour large-tonnage rotary drilling rigs，Be responsible for pile foundation construction of Wuhe Station。The Shenzhen section of Shenzhen-Dalian Intercity Railway traverses Shenzhen from east to west.，Seamless connection of 20 subway lines、5 intercity railways，4 high-speed railways，You can also transfer to the airport.APMLine and Pingshan Yunba Line.。The project is also to improve the passenger distribution system of Shenzhen Baoan International Airport.、Expand the eastward radiation capacity of the airport，To build an airport rail express line with high quality and innovative international aviation hub。Guangdong Nianxin Construction Engineering Co., Ltd.SR415 andSR445 enter the construction site，Excellent rock entry performance，Stable device status，It is well received by customers。After that, two sets were purchased in succession.SR525ProLarge triangle luffing structure drilling rig put into use。

Construction pile diameter of Wuhe Station Project: 3.2 meters，Pile depth 65m，Upper boulders are scattered，There are as many as 10 boulders in some boreholes.。The basement is mainly located in the strong~Slightly weathered granite，Rock strength 150MPa。Four-stage drilling with cutting pick and cone bit，The deepest core of a single pile is 55 meters.。This puts forward higher requirements for rotary drilling rig construction.。

TrinitySR415、SR445 andSR525ProAdopt high-power and large-displacement engine，Power is allocated in real time according to demand，Continuous output to cope with rock entry condition。Large lifting force of main winch，Calmly deal with underground emergencies。Equipped with double slewing reducer，Ensure that the hole is not deviated，Equipped with intelligent control system，The verticality of the drilling mast can be automatically adjusted and displayed.，Ffectively ensure that stability of the hole wall and the hole forming quality in the pile foundation construction proces。Apply pressure、Torque、Perfect match of core competencies such as promotion，Achieve hard rock、Deep Hole、Efficient Drilling of Large Piles、No fear of the breeze turning into hard rock。

The project is located in the urban area.，There is a time limit for urban construction.，Therefore, there are higher requirements for the stability of the equipment.。Trinity rotary drilling rig，Overall attendance rate up to 90 percent%Above，I really did it“Shift change of operator，The equipment is not off duty”，A proper perfect attendance award。

At the same time，SANY service engineer is on standby for 24 hours.，After-sale guarantee，Construction is more secure。The customer commented：“For us， Time is money ，Efficiency generates value。Stable and efficient construction of SANY equipment，We plan to purchase more Sany products in the future.！”

Customer buyback is the best brand endorsement.。Sanyi rotary drilling rig will also continue to contribute to the construction of major traffic projects.，Create value for customers，Establish safeguards for major projects。
