Embodiment Construction

[0032] The methods shown by these figures were developed to perform the given work as described in the opening paragraphs of this application. The method according to the invention and the device derived therefrom enable the treatment of soil layers consisting of silt or related materials to the desired depth with the aim of stabilizing these soil layers or introducing piles or foundations into them.

[0033] It is therefore essentially different from the techniques already used in the field to date, by injecting fluid under high pressure into the layer of soil to be treated, cutting, partly displacing and partly mixing the soil, while simultaneously injecting hardened binder. The fluid may be water or air (or a combination of both if necessary), to which a binder is preferably added.

[0034] The binder is thus injected into the loose soil substantially simultaneously with the fluid. Therefore, it is clear that the primary purpose of injection at high or very high pressures...

Abstract

The invention relates to a method for stabilizing a soil, wherein the soil mainly composed of the silt and / or the relevant material. In the method, the soil to be stabilized is loosened using a machine tool, such as a rotary blade and the cutting function of injecting the high-pressure fluid jet into the soil to be stabilized and meanwhile a hardening binder is injected into the soil to be stabilized. The stable soil has higher compressive strength. The invention also relates to a device for executing the method.

Description

technical field [0001] The present invention relates to a method for stabilizing soil consisting essentially of silt and / or related materials by injecting a binder into the soil. Background technique [0002] The term "silt and / or related material" should be understood to mean the various soil species which can form the subsoil of a watershed or location up to very variable depths. This type of subsoil forms part of, for example, bays, streams, rivers, docks, ponds, ditches leading to locks or mooring docks. The concept also includes swamps and areas for dumping silt. [0003] The field of application of the invention also produces a stable subgrade in said soil layer consisting of silt or technically equivalent material. Further areas of application are the construction of subsoil layers, shoals, etc. that are resistant to various forms of erosion. [0004] The techniques used to stabilize these very specific soil types by adding binders are well known. One of the most ...
