Powerful - TERRA MINI-JET lays HDPE pipes OD 225 mm in 50 m length with backreamer ? 300 mm

Product catalog summary

Project Overview: The document details a horizontal directional drilling (HDD) project using the TERRA MINI-JET system in Münster, Germany. The contractor, M/s Gerhard Rode Rohrleitungsbau GmbH & Co., executed the installation of four HDPE pipes with an outer diameter of 225 mm over a length of 50 meters.

Specifications: The project involved laying HDPE pipes with a backreamer diameter of 300 mm. The drilling fluid used was a special bentonite called MAX BORE HDD, suitable for the underground conditions of clay, gravel, and compacted dry soil.

Equipment and Setup: A truck equipped with a rear crane was specifically purchased for this project to facilitate the use of the TERRA MINI-JET. The setup included a shored working pit for the pilot bore and custom-built rod boxes for cleaning drill rods.

Procedure: The process began with the pilot bore, followed by the pipe pulling phase where 0.5 m long drill rods were pulled into the pit frame and disassembled. The successful installation of one of the four HDPE pipes is highlighted.

Contact Information: TERRA AG, located in Brittnau, Switzerland, provided the equipment and can be contacted via phone or email for further inquiries.
