Currently, technological solutions in the field of trenching are highly advanced. Trenchers are used for a wide range of services related to deep foundation forming. Trenchers are typically based on caterpillar body. A trencher operates like a chainsaw, a machine is equipped with a trenching chain, which digs up soil and mixes it with previously prepared bentonite/cement grout, forming a uniform partition, with anti-filtration or stabilisation purpose.
There are two methods of deep soil mixing, which assume trencher application:
- continuous wet deep soil mixing - prepared bentonite/cement binding grout is being mixed with native soil;
- continuous dry deep soil mixing - dry sealing mixtures are being mixed with native soil.
