HORIZONTAL AUGER BORING
Horizontal Auger Boring is a well established and cheap trenchless method that is widely used for the installation of steel pipes and casings under railway and road embankments for service pipes and waste disposal pipes. It is an economical pipe installation method that can be used in a variety of ground conditions to prevent open-cuts on pavement, and reduce disruptions to traffic as well as social cost.
OPERATION MODE
Horizontal auger boring is a trenchless technique employed to drill horizontal bore holes by rotating the cutting head. The cutting head is attached to the augers that stay inside the casings. Auger boring machine generates torque that is transmitted to the cutting head through the flighted tube.
The auger string is composed of connected augers end to end. One end of the auger string is connected to the boring machine and the other end is linked to the cutting head. The torque and thrust force generated by the boring machine are transported through the auger string to the cutting head. The rotation of the cutting head and augers can cut out the ground and remove the spoils from the front of the casing to the back. At the same time, boring machine can proceed forward using the hydraulic jacking force supported by thrust block. By repeating this operation, casing can be installed in the ground.
