Translation of "Bindiger boden" in English

Should the combination of the fill material--for example a strongly cohesive earth--justify the fear of a one-sided slip joint, then the forces created by this can be absorbed by building in diagonal bars or ropes designed for tension and compression forces.

The determination of the physical constants provides information on the engineering and soil physics properties of cohesive soils.

It can lead to a significant increase in the strength of cohesive soils.

Cohesive soils change their state depending on the water content.

PD models are well suited to heavy cohesive soils with high water contents.

PD-series models are primarily used on cohesive soils with high water contents.

Lime improves the paving properties and compactability of wet, cohesive soil.

Cohesionless soils are typically more erodible by jet grouting than cohesive soils.

Admittedly, at first, there is no improvement in the k-values as a result of the addition of dry sludge to cohesive soils.

The field vane tester is designed to examine the un-drained shear strength of soft cohesive soil in the fields.

It is thus possible to discharge the removed ground material in an especially environmentally safe manner, particularly given cohesive soils.

As a result of the higher surface roughness of the helix surface, the contact space between soil and helix is smaller with cohesive soils.

In contrast, in case of softer, in particular cohesive ground, the cutting teeth assume a large proportion of the ground removal.

For example on the one hand cutting teeth for sandy ground and on the other hand cutting teeth for cohesive ground can be used.

The diesel version of rammers offers superior compaction performance, particularly with heavy, cohesive soils.

For the treatment of silty soils a hydraulic fluidized bed reactor proved to be most suitable.

The VCIPC-method is efficient and cost-effective in primarily cohesive, and also organic ground with very low loadbearing capacity.

No restrictions have been identified with regard to soil texture. Even highly cohesive soils are suitable for this treatment.

Because of the limited permeability of clays, pore water in cohesive soils cannot immediately escape when a load is applied.

At maximum density, cohesive soils have maximum strength and load-bearing properties (high shear resistance (see below), low pore water pressure, low compressibility and low permeabi1ity).

For placing the injection boring anchor equipped in this manner, which is for example designed for cohesive ground, it is first used as a boring bar as well known, and air as rinsing medium is supplied to the central longitudinal opening 10.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a boring tube which insures in a simple manner, especially in cohesive ground, a central guidance of the boring tube and a reliable boring process.

It insures first of all that due to its steepness a relatively short flow path for a rinsing medium which carries ground particles is provided which in the cohesive ground as a rule is air, and also supports this transporting movement.

In the context of the invention, clays are understood to be materials of the type commonly used in the building materials and ceramics manufacturing industry, i.e. the very finely particulate, light rocks which are formed by the weathering of rocks rich in feldspar and which may be regarded as typical representatives of cohesive soils.

The described process is unaffected by the presence of large stones, coarse clays, binding or sandy soils in the earth core because this core is being pushed from the rear over the entire length of the pipe, the rate of advance depending on the pumping output of the drive units and being monitored through the control system.

In carrying out the process of the invention, a homogeneous mixture is initially prepared from the cohesive soil, with the addition of the pulverulent agent which forms a soft gel, in step (a).
