Japanese used construction machinery of the micro tunneling machine.

It is a micro tunneling industrial method of two process method.

Loads to the underground pipe are very few industrial methods because of the low load bearing ability method.

Highly accurate construction can be done with a small shaft.

The tube diameter that can be constructed is from 150 to 350mm.

All can be carried by 4ton career car with the crane.

This used machine is a superlative quality and a performance.

Construction process

It is a micro tunneling industrial method of two process method.

The first process corrects the position while pushing the pilot pipe.

The second process constructs the underground pipe while following to the pilot pipe.

It can watch the YouTube video of the micro tunneling industrial method of two process method from the following URL.
