ZTJN-80
· Used for trenchless pipe laying in wells (such as 3.5-meter round wells) or tunnels for horizontal drilling
· Can be used for "top-pull pipe technology" and micro-top construction
· The drilling rig is small in size and the construction working surface is small.
· Suitable for laying drainage pipes with a larger diameter of Φ1000mm (inclusive) or less (steel pipes, PE pipes, concrete pipes, glass fiber reinforced plastic sand-filled pipes, PVC thick-walled pipes, etc.).
