vacuum dewatering system trimix flooring

With industrial revolution all over the world. The floor construction has been one on the serious concerns of Architect, Engineers and users, A high quality concrete floor need not only be leveled it should also have a high compressive strength, minimize dusting at bare minimum cost. The Swiss vacuum De-watering system is designed to eliminate the ill effects of extra water presence inside the concrete. Through Vacuum treatment, the surplus water is removed from the concrete, which means that the water/cement ratio is drastically reduced after placing, A lowered water/cement ratio automatically leads to noticeable improvement of almost each of concrete properties.

Components of Swiss De-watering system

DOUBLE BEAM SCREED BOARD VIBRATOR
screed vibrator is used for the leveling as well compaction of concrete it consists of high quality steel bar (4.2 meter) with spacing of 250 MM in between. Special water protective vibrator motor is mounted in the center which produces 1830 N centrifugal force which is most ideal for compaction of green concrete. They are also available in different sizes from 2 meter to 5.5 meter.

VACUUM PUMP
This is the core of the system. A continuous discharge vacuum pump is complete self contained unit. The unit is mounted on a transportation trolley, 24 sq. meter freshly laid concrete can be De-watered in one single operation with one set mat. The pump is powered by 7.5 H.P. 3 Phase electric motor.
FILTER, SUCTION AND TOP MAT
Suction mat is placed directly on the green concrete after vi bro screed operation is over. A Special high class nylon filter is fixed on plastic mats which acts a filter during the vacuum operation filter mats in different sizes are provided with the system, Top mat is provided the junction box and is De-watering placed on top of filter mat for the purpose of sealing special synthetic cloth is used in the top mat it comes in standard sizes of 4x6 meter.

POWER FLOATER
It is surface grinding equipment powered by 3 H.P. Electric motor through gear box with floating RPM of 130. It grinds the surface to make it wear resistance.

POWER TROWEL
It is surface finishing equipments powered by 3H.P. electric motor through gear box troweling RPM of 135. It polishes the surface after floating operation and 3 to 4 passes are required for giving fine finish to the floor.

1. FORM WORK Construction of floor begins with careful preparation. Before casting MS Channel are generally used us form works. They act as a stopper, also as support for pulling the screed board vibrator.

2. NEEDLE VIBRATION
Once the concrete is poured in panel, it is poker vibrated by needle for compaction stone, gravel and cement.

3. SCREED VIBRATION (SWISS VACUUM DEWATERING PROCESS START)

Needle vibration never gives a nearly level surface, but when this type of vibration is combined with screed vibration the concrete surface becomes level and smooth screed vibration insures over all compaction of concrete.

4. VACUUM PROCESS
The surplus water is extracted out of the concrete by the vacuum pump. Vacuum De-watering lowers the water ratio in the concrete by 15-25% which meres es the compressive strength and wear resistance of the concrete. Vacuum process takes only 5 minut per inch thicknes of the concrete slab. The Concrete is driven and compacted so tightly that a man can walk on the fresh concrete directly after it is vacuum treated.

5. FLOATING
The floating operation takes place immediately after the vacuum De-watering & after mixing and grinding of cement takes place. The Cement particles are split apart and mixed with the sand particles which gives a very strong and wear resistance surface.

6. TROWELING
In order to further improve the wear resistance and fine finish, the concrete surface is power troweled.

SWISS VIBRATORY EARTH COMPACTOR

These are self propelled, light in weight and compact machines having high forces, low amplitude and high frequency, based on the principle of reciprocal pressure generation by frequency undirectional impulse vibrator which causes the ramming and forward movement. Swiss Earth Rammer can compact thicker layers of non-cohesive and semi-cohesive soils and maximum proctor density (95% to 98%) are achieved in less numbers of passes application non-cohesive soil, subgrades, maneuvers close to abutmants retaining walls, pilling, ideal for key trenches, cannel embankments, back fill jobs, factroy floor, foundations, bridge approaches etc.

A. BAR CUTTING MACHINE
(Hydraulic) Cut capacity upto 40 mm.

B. BAR BENDING MACHINE
28 mm to 40 mm bending
SWISS CONCRETE/ASPHALT CUTTER

Swiss groove cutting machine is ideal equipment for cutting the hard concrete for expansion joints. Dummy joints (Shrinkage control joint.) Asphalt pavement cut, pot hole repair cut. Light in weight makes it easy for one operator to handle easily, gives accurate require depth cut as control mechanism if fitted in the machine, water spray attachment, powered by electric motor. Water pupm optionally, required party.
