WHY VIBRACORE FOR SOIL CORE SAMPLES

VIBRACORE CORE DRILLING TECHNOLOGY

The Wink Vibracorer operates on the principals of powerful vibration applied to the target soil and sediment particles that the equipment contacts. When soil or sediment particles are vibrated at high frequencies, they lose their static strength and allow our steel drill rods to pass through - advancing down through the strata. This vibrating action also aids the target material to flow into the core barrel.

Other Core Drilling Technologies ...

Other available technologies used for soil sampling involving 'push' and 'hammer' principals employ hammering mechanisms and hydraulic rams - which can usually be compacting actions. When soils and sediments are subject to compacting forces, they can be more difficult to force into 'core barrels' for collection - often resulting in reduced or distorted capture. Rotary coring (including hollow core auger) equipment tends to churn and mix the soil and sediment - resulting in more disturbed sample cores.

WHAT IS VIBRACORE FOR SOIL CORE  SAMPLING

The Key to the WINK Vibracore Drill is simple – the principle of vibration. The Vibracore drill head, is powered by a 6.5 h.p. Honda engine, generates 7,000 to 12,000 acoustic vibrations per minute and transfers them to the drill string. This action, aided by the weight of the equipment itself, mobilizes the particles coming into contact with the drill rods, instead of churning, hammering or pushing the sample like other drilling methods.

And because Vibracore works by vibration, not by rotation or percussion, there is no need for drilling fluids, which could contaminate the sample or hinder operations in remote or severe cold weather.

Compact, lightweight and simple to operate, the Wink Vibracorer is built with portable technology that reduces costs and makes soil sampling in remote areas more affordable. The result of this innovative design is a finely tuned machine capable of coring intervals of 1.5m (5 feet) in 60 seconds and penetrating a variety of unconsolidated materials to record depths. And most important, the Vibracorer is able to collect minimally disturbed, truly representative (in situ) core samples.

ACCURATE SOIL CORE SAMPLES

The vibration frequency of the Vibracorer is adjustable, allowing the operator to tune into the natural frequencies of the strata and equipment involved, control the rate of penetration and collect optimal, in situ samples. A continuous soil or sediment sample flows into a core barrel for later retrieval and laboratory analysis.

Preserved soil core (in situ) samples  can best be preserved inside Rigid Plastic Tubes lining inside the steel drill rods.

Conventional soil classification tests, EPA toxicity tests and bio-assay analyses are some of the analysis that can be conducted from samples retained in rigid clear plastic tubing or soft poly tubing.

EASY to TRANSPORT, EASY to OPERATE

One of the Vibracorer’s most impressive features is its portability. The drilling power is packed into an efficient package, which includes the 37 pound Drill Head, 61 pound Honda driven Power Plant, 27 lb Flex Cable drive cable, Gin Pole hoisting and pull-down system, Drill Rods, Core Bits and Core Retainer spring.

The vibracore system is easily carried by two people, making it ideal for remote sites and deployment over water and in tight locations. Save access costs as this drill can be carried by light truck, ATV, helicopter or by hand.

The longest piece of equipment is only 62" (1.58m). The heaviest single component is 61 lbs (32kg). At the site, the Vibracorer and its accessories are simple to operate, maintain and move between nearby locations - with a minimum of previous training required.
