Services - Horizontal Boring
.......................................................................................................................................

Cross-country pipeline passes across High ways Roads and Rails where the pipe (carrier) is protected from external Earth burden, traffic load and live load. Steel casing pipes are used for this purpose. As the traffic on roads and rails are un interruptible the casing pipes are normally installed by Horizontal boring method. Our fully Hydraulic and semi electric boring machines are utilized at least 75% of the year. The fully hydraulic machine pushes the casing pipe bellow the service Road / rail using hydraulic power. We have capacity to do 30”, 50 Meter crossings with the present machineries available.

Road Boring Equipment.

This equipment consists of a power source, Torque converter, Auger, Cutter etc. The auger and cutter are protected by the torque converter, which ensures smooth and shock free drive. The heavy duty thrust type bearing provided to drive the auger and cutter is capable of exerting a horizontal load to the order of 5 to 50 MT.

The Power source is a diesel driven Electrical power generator and an electrically operated hydraulic power pack. This delivers the required torque and force for the system. The Torque converter is a system of fluid coupling, reduction gear unit and chain drive.

The Auger is made of suitable abrasion resistant steel and of standard length of five meters. Conveying of excavated and reamed earth is done with the movement of auger. The Cutter assembly fitted in front of the first auger is fitted with cutting teeth of various hardness to suit the soil. They are also replaceable on wear.
