4.deep drilling and newly researched

 

1.   Uses

 

  This kind of  Long Screw Holes Machine is broadly applied to the foundation construction of industrial and civil building, and is a environmental-friendly piling mechanical product which is specially used in urban construntion.

 

2.  Features

 

  This long screw drilling machine is a kind of deep drilling machine developed by the company. 

 

  The  pile holder adopts ship like track,caterpillar type travel with flexible displacement and convenient emplacement.

 

   The drilling machine applies electrohydraulic concentrative control which is convennience for operation.

 

  

   It has three-point support upright post that can be adjusted at the back and forth or on the left and right.The whole machine can realize the 360°revolution.

 

The part of drilling tools apply three ring decelerator for power, key type flange as drill rod being safe,reliable,and shortcut dismantling.

 

  The drilling machine can be equipped with construction techniques such as superfluid, high pressure slurry filling and dry method bore forming.

 

3.  Security&Usability

 

 

  In the pile operation, this machine has high pore forming efficiency, good quality, no shock, noise or pollution and high degree of mechanization.

 

  It has better performance than hammering and pile sinking methods for penetrating the sand and gravel layers, at the same time, it can avoid the adverse effect on the adejacent buildings due to the hammering and vibration pile sinkings press on foundation.
