Product Description

 

What FAE jet grouting could offer?

Jet Grouting or High Pressure Grouting can be employed in all soils 

from clays to coarse gravels irrespective of grain size distribution, void 

ratio or pore sizes. Jet grouting uses a high pressure jet(approx. 400 bar) to cut the natural soil in order to mix and partially replace it with the

grout. This creates a "soilcrete" body whose strength and/or permeability characteristics are independent of the original soil fabric.

Jet Grouting Methods

 

FAE uses three different methods for jet grouting:

 

Simplex-Method

 

Cement grout is injected into the soil with high pressure (approx. 400 bar) at the drill head (monitor). The jet cuts the soil and mixes it thoroughly with the grout. The Simplex~method is appropriate for shallow depths and horizontal jet grouting.

 

Duplex-Method

 

Using special rods with double inner conduit (Duplex string) compressedair is introduced into the grout jet at its exit point. This adds energy andenables the Duplex~method to reach much greater depths and achieve 

larger diameters than the Simplex-method.

 

Triplex-Method

 

The Triplex~method uses a high pressure water jet with compressed air 

to cut the soil. Cement grout is introduced into the soil and mixed with itthrough a separate jet nozzle situated just belowthe jet nozzle for the 

water (Triplex string with triple inner conduit rods). The Triplex~method isan appropriate method for underpinning, especially in cohesive soils.

 

Dimensions

 

Different geometric forms and dimensions of the soilcrete body can be 

produced with jet grouting:

1~without rotation of the rods during withdrawal and jetting, cut~off 

walls of various thickness can be produced;

2~ with partial rotation, segments of a cylinder can be produced (bow-tie); 

3~with full rotation, a cylindrical body is produced; diameter of the 

cylinder can be changed by varying withdrawal rate and/or jet pressure.

 

 

Jet Grouting Parameters

 

Jet grouting parameters which are chosen for a given project depend on the required characteristics of the finished product, the geotechnical

characteristics of the soil and the chosen jetting method.

 

Principle jet grouting parameters are:

~withdrawal rate of the jet string

rotation speed of the jet string

flow rate of the grout

jet pressure

jet volume

number and diameter of jet nozzles 

volume and pressure of compressed air

mix design of the grout

 

Applications of Jet Grouting

underpinning of existing structures

downward extension of foundations in the case of settlements or 

increased load

~soil improvement, even underneath existing structures

vertical impervious barriers

impermeable base for excavations

bracing and stiffening of excavations underneath their base

connection of sealing walls to existing structures and/or services and 

utilities

walls for cylindrical or polygonal excavations

horizontal screens and canopies for tunneling

soil stabilisation between neighbouring excavations or foundation 

works

impervious connection of individual piles in pile walls
