Cutter soil mixing (CSM)

Cutter soil mixing (CSM)
The production of soil mixing elements through insertion of a rotating cutting head.

For cutter soil mixing rotating drums break up the soil structure. Simultaneously a self-hardening binding agent suspension is added. The binding agents used are mainly cement types or mixtures of cement and bentonite. These are mixed with water to form a suspension. The drums of the mixing tool rotate around the horizontal axis so producing soil mixing elements with a rectangular cross-section.

Examples for cutter soil mixing

  • The mixing equipment for cutter soil mixing consists of a rectangular Kelly bar and the cutting head.

  • As the cutting head penetrates the ground a binding agent suspension is introduced through an injection pipe and mixed with the soil.

  • During extraction the binding agent is further added in doses. Thereby the soil mortar is mixed rotationally a second time.
