The PE trenchless pipe was originated in the 1970’s and was introduced into China in the 1990’s. Currently, it is widely used for the field of pipelines’ construction, such as water supply, drainage, electricity and communication pipe. Also, it is widely applied in the field of pipeline restoration, protection of cultural relic and ancient buildings, and so on.

Trenchless through pipe installation
Adopting the underlying digging pipe laying and pipe jacking machine pipe laying technology.
1. Introducing the measurement and control for pipeline’s track.
2. Greatly increased the pipe laying ability (200 meters in length and 3 meters in diameter).
3. Fast and efficient.
4. Improve the ability of construction in complex underlying conditions.
5. Making it possible for in-situ remediation of the old pipe.
Suitable for laying PE pipes is not more than 3000mm in diameter are adopted.
