Michels completes record-length Direct Pipe installation

Michels Corporation continues to push the limits of trenchless technologies by completing a record-length Direct Pipe installation under the Dow Barge Canal in Freeport, Texas.

The 4038 ft installation is a North American record for Direct Pipe.

Michels used a Herrenknecht 750 t pipe thruster to push the 48 in. dia pipe string through a challenging alignment and into a shallow exit pit on 28 August. The project was completed in two months, and runs under a flood control levee, Dow Barge Canal, a rail crossing and multiple road crossings.

In addition to completing the record-setting Direct Pipe installation, Michels worked with owner Phillips 66 and general contractor Troy Construction from the project’s inception to ensure an optimal design and maximum potential for success.

The technology

Direct Pipe is a one-pass technology that combines aspects of horizontal directional drilling and tunnelling to install pipes. It is particularly effective for crossing under levees, waterway, rail tracks and roadways because the borehole is continually supported and because of a greatly reduced risk of inadvertent fluid returns.
