Backyardcrossing in Bernese Oberland - TERRA-HAMMER T 105 F

The T 105 F earthmover renews the drinking water system in the community of Bönigen.
The company Gerber + Troxler Bau AG from the Bernese Oberland is rehabilitating the drinking water system. For the trenchless installations, especially house connections, the new piercing tool TERRA-HAMMER T 105 F was used. With the oversized end sleeve the 105 mm machine also allows pulling in of bigger pipes as in this case a 112 mm short pipe. The piercing tool was set up in the natural stone masonry within the basement. From there it drilled and installed simultaneously the protective pipes underneath the 7 m backyard. Into these protective pipes will then be installed the product pipe.
