Trench Cutting Re-mixing Deep Wall Machine

Model: TRD7095, TRD4585


Wall Width Range: 550-950mm.

Wall Depth Range: Max 70m.



1)Projects: For anti-penetration in areas with abundant groundwater, used in subways, large shopping malls, dam reinforcement, contaminated soil treatment and other projects.

2)Geology: For clay soil, sand, gravel and gravel layers. It also has good applicability in dense sand layers with a penetration value of 30~60 and soft rocks with a saturated uniaxial compressive strength not exceeding 10MPa..

Working Principle

1. After the chain-blade cutting tool is cut vertically and continuously to the design depth, it is pushed horizontally and injected with cement slurry to form a continuous, equal thickness and seamless cement wall.

2. Insert core material (H-shaped steel, etc.) into the cement mixing wall of equal thickness to form a composite retaining and water stop structure.

1. The cement is evenly mixed, and the unconfined compressive strength is 0.5-2.5MPa;

2. The wall has good water resistance, and the permeability coefficient canreach 1×10-6 cm/s to 1×10-7 cm/s in sandy soil;

3. The spacing of the interpolated profiles can be evenly arranged withequal spacing, and the rigidity of the enclosure is more uniform;

4. The maximum height of construction machinery is generally not more than 12 meters, and the center of gravity of construction frame is low, with good stability.
