Another world super project is coming! Hard Core Power of XCMG Rotary Drilling Rig

April 07, 2024

Recently

Nearly ten XCMG Rotary Drilling Rigs work togetherHangzhou Bay Sea-Crossing Railway Bridge The first bored pile of the South Channel Bridge has been successfully completed.

Construction officially entered“Fast lane”

This is the presentIn the world

The longest length under construction、The construction standard is the highestYes

Sea-crossing Bridge of High-speed Railway

The whole journey crosses the Hangzhou Bay

It's in the worldThe First Strong Tide Bay Bridge

Hangzhou Bay Sea-Crossing Railway Bridge is 29 in total length.2 km,Hangzhou Bay is one of the three strongest tidal bays in the world.,It's typical“A trumpet-shaped bay”,Maximum Tidal Range 8.69 meters,Maximum flow rate 5.3 meters/Seconds,Large tidal range、Strong scour、Rapid flow speed、Deep silt layer and shallow gas occur frequently.。

Let the high-speed train fly across Hangzhou Bay.

The difficulty of pile foundation operation is not small.

Nearly 100 pile foundations

Only the real strength can be competent.

After comprehensive consideration

The project party finally chose XCMG.

New challenges,New construction method。The deepest pile foundation hole is over 156 meters.,During construction of bored pile,The joint project personnel of XCMG innovatively adopted“Rotary drilling overburden pilot hole”And“Hole formation by reverse circulation drilling machine”Combined process,And that verticality of the drill hole is ensured.,Continuous construction for 240 hours,Successfully completed the first pile task。

High power engine、Multi-gear drilling mode、Super torque power head、Rotating platform with large vertical plate box structures,Brand new and upgraded“F”XCMG series Rotary Drilling Rig,And that efficiency is high、The rock entering ability is stronger.、The operation is more stable、More convenient disassembly and transportation of the whole machine。

Construction pile diameter 2.5-2.8 meters、The average pile depth is 131 meters.、One pile is formed in 3 days on average.……Specific hole forming speed、Quality of racing pile,Xugong handed over a satisfactory answer to the construction party.。

To meet the diverse needs of application scenarios with excellent product quality,XCMG keeps improving its foundation,The pursuit of excellence,It shows the hard core strength of a big country's heavy weapons.。With the steady progress of the early construction,,All kinds of equipment of XCMG are entering the front line of the project.,The combat corps continues to grow.。
