82 m (Ф2.8 m) Super Deep Pile, One Gold in Two Days, Four Rotary Excavations in Thailand First Appeared "Dian" Peak

December 01, 2023

Recently,Gold Thailand Four New ProductsSH58FMultifunctional Rotary Drilling Drill First Appeared in Yuwei Expressway Section of Lijiang City, Yunnan Province-Pile Foundation Construction of Liming Bridge。The drilling diameter of the project is large.,Depth is deep、Formation is hard、Abundant sand layer、The hole is easy to collapse、The process is complex、The construction period is tight,The construction is difficult.。Gold Thailand Four New EquipmentSH58FThe sixth root is now completed, with a depth of 82.mUltra-deep bored pile,The construction speed is fast,High pore-forming quality,Highly recognized by the conTractor

SH58FMultifunctional rotary drill

Yuwei Expressway Section-Dawn Bridge ProjectPurposeIt is an important part of the Yunnan-Tibet transport corridor.,It is the main component of the Great Western Yunnan Tourist Ring Line and the Great Shangri-La Tourist Ring Line in Yunnan Province.,To maintain stability in Tibetan areas.、Promoting ethnic unity in border areas、It is of great significance to promote local economic development.。

Description of stratigraphic distribution

Strata of the Project:0m~27mIt is pebble layer,27m~30mStrongly weathered mudstone,30m~49mIt is stone mudstone,49m~70mIt is a sand layer,70m~75mStrongly weathered sandstone and mudstone,75m~82mIt is a sand layer,The actual construction stratum is hard and the sand content is as high as 30%The above holes are easy to collapse。In view of the geological characteristics,,Adopted on site”Rotary excavation+Reverse circulation sand remover”Carry out the construction according to the process method.,On the basis of summing up the construction experience of the first ultra-deep pile, the conTractor and Jintai technicians,Stick to it“Due to pile control、Take various measures simultaneously”Principle,And ensure that pore-forming quality。The efficiency of ready-made piles is 60 hours./The root is gradually raised to 48 hours./Root,Overall efficiency increased by 20 percent%Above,It provides a strong guarantee for the follow-up construction progress.。

SH58FIt is Shanghai Jintai to adapt to big bore.,Large Rotary Drilling Rig developed under the working conditions of ultra-deep piles in rock strata.:It has eight advantages,Unstoppable!

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

2、With powerful torque and lifting capacity, it is the preferred equipment for big bore of ultra-deep piles in complex strata。

3、Solid rail technology,Precision machining and forming,High pore-forming quality、Low noise。

4、Professional grade hydraulic components,High output power;

5、Multi-gear control,Rock entry adaptive technology and visual operation,Drilling is efficient。

6、Main winch with single-layer long drum and double heavy-duty speed reducer,The effective drilling depth of single-layer drum can reach 136 meters.;

7、The chassis layout is reasonable,Large space,And that maintenance is convenient。

8、Visualization technology of pressure stage,Reduce drill pipe failure,And that construction efficiency is improve。
