Liquid Soil is a construction material which is flowable during installationand which may be produced from nearly any kind of excavated material

ApplicationsLiquid Soilmay be used in most backfill situations, such as filling utility or service trenches, backfilling excavationson construction sites, filling voids, tunnels and galleries and use on site requiring large quantities of material.

Liquid Soil also offers the possibility of hanging its properties to suit the individual application requirements.

LI QUI D SOI L FOR

TELECOMMUNI CATI ONTRENCHES

Liquid Soil is a material which can be produced from nearly all type of excavated material and used in

site, such as for example in the case of a trench in urban site for the installation of

Telecommunication wires or services.

In this case Liquid Soil become a rapid and easy way to use a discharge product - reducing drastically

the stand-by time and installing of the undertaken services- in a sustainable way!

The following picture sequence shows how an existing bicycle path/sidewalk made with slip bricks,can be opened and rebuilt in an easy wayas nothing happened!

The mixed soil obtained with Liquid Soil becomes hard in a few hours avoiding all dangerous and badeffects of the natural subsidence of t he traditional refilling methods.

The use of small equipment (installed on mini-excavator or mini-dumper) is more suitable for small

works where the agility is priority and spaces are small.In case of big quantity of treated soil with high daily production, the use of bigger equipment with

concrete mixer truck is required.

Backfill using RSS Liquid Soil

Much reduced construction time using RSS Liquid Soil

Sewer ConstructionInstallation under congested conditions of a large diameter

The Challenge

The Solution

LOGIC developed a technical solution for Karl Krumpholz Rohrbau GmbH,

who used the properties of RSS Liquid Soil in such a way that the specified

load could be achieved without an expensive reinforced concrete trench bed.

This solution was put into place as an amendment by Karl Krumpholz Rohrbau

GmbH. The project was completed to the client's satisfaction within time and

on budget.

In Bamberg a 2000 mm main sewer had to be installed in the Jckstrae

whilst maintining single lane traffic. Because of the 6-7 m depth, sheet piling

trench support was used which in turn called for an expensive concrete trench

bed. In order to minimise the trench width, partial backfill with RSS Liquid

Soil was specified since it would otherwise not have been possible to finish

construction within the time allowed.

No disruption to traffic flows

Float-laying a sewer using RSS Liquid Soil

Sewer ConstructionFloat-laying a sewer in difficult ground conditions

The Challenge

The Solution

RSS Liquid Soil and the use of RSS pipe-laying acessories with floating pipe

supports with no fixed connection to the soil bed. This gives consistent soil

conditions which isolate the installed pipes from the heavy trafic loading and

avoids long-term differential settlement.

Installation of a wastewater pipe in very difficult, unstable ground sensitive to

vibration with up to 7 m peat soil at the entrance to the port area of Lbeck.

The area is intensively trafficked by heavy lorries. Avoidance of subsidence

and the production of made ground with similar bearing properties to eventual

nearby road construction particularly in the pipe trench area.

Sewer ConstructionBackfill in the road and pavement area

The Challenge

The Solution

RSS Liquid Soil allows all voids in these areas to be backfilled without

subsidence or shrinkage without using mechanical compaction. Damage

may be reliably avoided and the backfilled pipes remain accessible at

any time.

Backfilling around a multiplicity of crossing cables and conduits in an extremely

congested space. Conventional compaction would probably lead to subsequent

subsidence or impact damage.

The Challenge

The Solution

Comprehensive trials resulted in the possibility of incorporating this material

into RSS Liquid Soil, used to backfill the trench. Not only was replacing the

soil avoided, but below-ground consistency was restored, reliably avoiding

differential subsidence.

As forecast in the soil investigation, blue clay with up to 20 percent by volume

organic inclusions was encountered. Using traditional methods, all this material

would have been disposed of in a landfill.

The Challenge

The Solution

The use of Combi-Manholes, specially designed to accomodate local

hydraulic conditions, allowed all the associated pipework to be laid and

backfilled in a trench only 1.25 m wide including shuttering. Since the backfill

was carried out using Liquid Soil, fast and efficient construction under

optimum bedding conditions became possible and the planned removal of

excavated soil was avoided. This resulted in large cost savings and minimal

environmental impact.

The Challenge

The Solution

The backfill material was produced dust-free on-site by the first mobile mixing

plant specially designed to handle RSS Liquid Soil. The machine was equipped

with special accessories for use with the wheel loader. Quality control was

provided by PROV who gave support during the construction phase to the

complete satisfaction of the client.

Construction was carried out close to surrounding residential property

where RSS Liquid Soil needed to be produced on-site from the existing

excavation. The client was therefore highly demanding in terms of environ-

mental management of the site.

The Challenge

The Solution

The use of RSS system components allowed the full possibilities designed by

the planner to be realised despite cramped site conditions. The RSS Combi-

Manhole allowed drainage and wastewater lines to be connected to a single

manhole. The volume of excavated soil and the consequent space requirement

was reduced by 60% in comparison to a traditional design.

The separate sewer system was designed as a 1000 mm rainwater reservoir

for use as grey water or by the fire services.

The Challenge

The Solution

The use of RSS Liquid Soil led to an optimum organisation of the construction

site. Since quality limits had been certified by PROV from the very start, con-

struction of the road base could be started a few hours after backfilling had

finished. The use of RSS Liquid Soil ensures that no subsidence will occur

and that the best bedding quality will be achieved.
