Construction of "Pearl River Delta" Super Project, XCMG Rotary Drilling Rig Construction Busy!

June 11, 2024

“Dragon Boat Festival”Period

On the construction sites of key projects all over the country

XCMG front-line builders stick to their posts

With“ Vacation ”Is the duration

Go all out of the project construction“Acceleration”

With passion and sweat.

Help the high-quality construction of the project

AtXijiang Bridge Section of Zhuhai-Zhaoqing High-speed Railway

Project construction site

The machine roared、Vehicles shuttled back and forth

A busy scene

Six XCMG large-tonnage Rotary Drilling Rigs

It is making every effort to promote the construction of the project.

Zhuhai-Zhaoqing High-speed Railway

Connect to Zhuhai、Jiangmen、Foshan、Zhaoqing 4 cities

Among，Xijiang Bridge Section of Zhuhai-Zhaoqing High-speed Railway

It is located in Zhaoqing New District/Yong'an Town, Dinghu District

It's the Zhuhai-Zhaoqing high-speed railway（Gao Zhaoduan）Project

An important project across the Xijiang waterway

The total length of the main bridge is 1307.6 meters

The average height of the bridge tower is 172 meters.

It is the first three-tower composite girder railway cable-stayed bridge in China.

Also at presentThe largest span in the world

Railway Cable-stayed Bridge with Steel Box Composite Girder

▲Zhuhai-Zhaoqing High-speed Railway（Gao Zhaoduan）Rendering of Xijiang Grand Bridge

Three main piers need to be sunk to the bottom of the water.

The water area where the main tower foundation is located is about 30 meters deep.

And the construction project is in

Typhoon-prone area and Huangsha clam protection area

……

Bridge construction is facing many difficulties.

After comprehensive consideration by many parties,

The project side finally chose Xugong.

Six in total

Large tonnage Rotary Drilling Rig group of XCMG

With exquisite technology and excellent performance

Successfully overcome the complex formation、The construction period is pressing

Heavy tasks and other difficult problems.

Demonstrate great strength

In the construction of deepwater foundation，XCMG adopts the innovative construction method of steel casing and super-large rotary drilling，Ensure that the hole is formed at one time，The construction efficiency is greatly improved.。

At the same time，XCMG attaches great importance to environmental protection，Strictly carry out the mud outward transportation，And actively protect the water source during construction.，Ensure that the project meets all environmental requirements。

The total number of pile foundations for the bridge construction is 112.，Pile diameter is 3m，Pile depth up to 107 meters。Faced with such a great challenge.，The large-tonnage Rotary Drilling Rig group of XCMG has demonstrated its strong strength.。Their average pore-forming period is only about 10 days.，Speeding up the construction of bridge pile foundation in an all-round way，It laid a solid foundation for the stability and safety of the bridge.。
