On the Bank of the Pearl River, XCMG Rotary Drilling Rig Helps Build a Super Project!

Recently，At the construction site of Shiziyang Passage Project in Guangzhou，XugongXR500E、XR460DRotary Drilling Rig goes into action，Put down the rod、Drilling、Lift the lever、Throw the soil at one go，Helping the construction of the world's super-long span double-deck suspension bridge！

Shiziyang Bridge is the key control project of Shiziyang Passage.，XCMG Rotary Drilling Rig is responsible for the right side of the east main tower of the bridge.More than 400Construction of cast-in-place bored pile，Pile diameter2mTo 3m，Maximum hole-forming depth61.7m，The average depth into the rock is about20m，Rock hardness80-120Mpa，This puts forward higher requirements for Rotary Drilling Rig construction.。

Facing difficult construction conditions，XCMG rotary drilling rig lived up to expectations，Average3 to 4 days into a pile。The service personnel of XCMG are stationed at the site to ensure the construction progress，Speed up and increase efficiency for successful completion of the project。

As the main model of this construction.，XugongXR500ERotary drilling rig is equippedMulti-gear drilling mode，Matching optimal torque and speed for different formations，High efficiency and energy saving；High-torque power headStrong into the rock，The construction effect is directly full.。In addition，Main winch adopts XCMG to lead the industrySingle row rope technology，Effectively solve the problem of wire rope wear；DedicatedTelescopic crawler chassis，Strong resistance to overturning，Complete machine transportation without fear of transfer！

As a new river-crossing super project in Guangdong-Hong Kong-Macao Greater Bay Area，The completion of the Shiziyang Passage will further promote the interconnection of infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area.，Help build a one-hour life circle in Guangdong-Hong Kong-Macao Greater Bay Area，Effectively alleviate the traffic pressure of the Pearl River Estuary crossing channel。
