Efficient Construction | Shanghai Jintai Multifunctional Rotary Drilling Drill Shows Its Skills!

Recently，Shanghai Jintai's fourth national new productSH58FMultifunctional rotary drill in Yulong, Yunnan（Xionggu）To Weixi Expressway Section-Demonstrate One's Skills in Pile Foundation Construction of Liming Bridge。

At present，SH58F6 multi-function rotary drills have been completed, with a depth of 82mUltra-deep bored pile，Due to the fast construction speed，High pore-forming quality，Highly recognized by the conTractor。

Jade Dragon（Xionggu）The project of Weixi Expressway is an important part of the Yunnan-Tibet transport corridor.，It is also the main component of the Great Western Yunnan Tourist Ring Line and the Great Shangri-La Tourist Ring Line in Yunnan Province.，There are many villages and towns along the line.，It is of great significance to promote local economic development.。

Due to the large sand content of the stratum at the construction site of the project,，Hole collapse is easy to occur，It was adopted on the spot“Rotary excavation+Reverse circulation sand remover”Carry out the construction according to the process method.。At present，Pile-forming efficiency from 60 hours/Root up to 48 hours/Root，Overall efficiency increased by 20 percent%Above，Provide a strong guarantee for the smooth progress of the project。

SH58FMultifunctional rotary drill

SH58FThe multi-function rotary drill is designed for big bore.、Super deep pile、Large Rotary Drilling Rig developed for hard formation and other working conditions，It has the following characteristics：

1、Adopt a new generation of countriesⅣCummins engine，Powerful、Low fuel consumption。
