Outline of the Soil Blender Method

The Soil Blender Method is a soil capacity improvement method by solidification. It uses "The Trencher" to Mix and Blend the original soil with slurry type improvement material.
The procedure starts with attaching "The Trencher" attachment to a regular backhoe, then pressure feed slurry type improvement material from a mixing plant to the injection nozzle near the tip of "The Trencher" with a grout pump, mixing with pressured air and continuously jetting, mixing and blending to form a improved soil mass.
It is a popular solution to prevent the liquidification of soil in recent years.

Advantages of the Soil Blender Method

1. The Improvement Depth reaches 17m

First, select the size of Back-hoe type base machine and the length of "The Trencher" attachemnt in according to the required improvement depth.
The Improvement Depth can reach up to 17m with 85 ton class base machine.

2.Can Efficiently Blend Soil, Low Strength Dispersion

Vertically blending through mixed layers of soil is the best way to create a homogenious soil, combining with the unique shape of the blending blade and the jet grouting of the slurry to realize the improved soil mass with low strength dispersion.

3.The Big Advantage in Mobility

By using the mobile Back-hoe as the base machine, it can easily operate in difficult construction conditions, such as soft soil, slope, narrow site, and site with limited overhead clearance, which usually troubles other methods.

4.The Reliable Management System

The monitor screen in cockpit shows the vertical angel of the trencher, the depth and the chain rotation counter. The output of these monitoring data will ensure the reliabilities of the construction management.

 

5.Ensure the Safety of Neighboring Structures

Continuous vertical blending and mixing motion of the trencher will ensure the slurry injected at the bottom tip of the trencher will be evenly blended upwards, and the injection pressure will be released through the surface of the soil. It will minimize the effect of the grouting to the sorrounding soil.
