In-situ Soil Processing｜L&R (Enlargement and Reduction) Geo-Fine Method

L & R Geo-Fine Method

※L&R : Enlargement and Reduction
L & R Geo-Fine Method is in-situ soil processing using enlargement and reduction system. Since it depollutes the soil in-situ without excavating the ground, polluted soil is not spread around, which enables a quick and economical processing. The agitation methods has adopted the enlargement and reduction method that processes soil in-situ by expanding only necessary depth so that more effective constructions can be applied to in-situ insolubilization of heavy metal and in-situ purification of VOC.

Features of L & R Geo-Fine Method

More effective method because it improves in-situ ground by expanding only necessary depth.

No need for earth retaining works and a yard for processing because polluted soil is not excavated.
Excellent mixing function because of simultaneous forward and reverse rotation of the drilling/mixing part.
Since the middle ground is drilled with a reduced diameter, even a hard layer can be penetrated easily.

Quick processing with simultaneous injection of three types of fluid.

Three types of fluid can be injected simultaneously in small quantity by using a special 3-fluid swivel and three independent tubes, construction by one process is possible.
Easy maintenance and fix problems, since the injection process is clear with independent tubes.

Large diameter up to 2,000 mm is possible.

From 1,000 mm to 2,000 mm column construction depending on site condition.

The central control system monitors the injection of agent real-time.
