High frequency vibration. Power Vibro Corer sampler allows you to quickly penetrate into the various unconsolidated sediments (silt, clay, sand). Coring pipes of different lengths. Used 3 and 6-meter auger tube with PVC liners with an inner diameter of 106 mm, core recovery is over 90%. Durability. Vibro Corer has high performance over many years, even in extreme conditions.
Working with a small boat. Vibro Corer assembled by hand for 2-3 hours, work can be done with a relatively small vessel. Deep-sea work. Vibro Corer designed to operate at a maximum depth of 300 m. A modified version is designed to operate at a depth of over 600 meters.
Electric Vibration Sampler SEABED
|Electric Vibration Sampler Company SEABED SVC-series has a great track record and has been successfully used by our company all over the world on different types of soils, including soils containing gravel.
Electric companies SEABED Vibro Sampler was designed to produce a cylindrical core sampling in soft soils and viscous at a maximum depth of 50 meters (standard version).
Standard set for Vibration Sampler includes 3, 4 and 5-foot frame, as well as other sizes available at your convenience. Two tubes with a diameter Ø70 mm or Ø108 mm. When all the components are mounted on the support frame relative to the entire unit is easily transported via a 20-foot.

CPTU is the most versatile tool currently available for field studies of soils. In addition to indentation resistance and abrasion friction cone sleeve (traditional CPT), measurement of the pore pressure (u) gives important information about the properties of the soil. The battery-powered probe with the transmitter mounted at the end of 36 mm and CPT rod is pressed into the ground at a speed of 2 cm / s. Passing through the various layers of the soil, the probe registers a change in their properties, typically once per second. The data are continuously transmitted to a computer operator at the surface.

Wireless CPTU - universal tool for field studies of soils

CPTU is a very useful tool for field studies of soils. In
addition to the penetration resistance and the friction of the cone
friction sleeve (traditional CPT), measurement of the pore pressure (u)
gives important information about the properties of the soil. Built-in
inclinometer will give you the opportunity to know the deviation from
vertical direction of pressing, and will help you calculate the actual
depth sensing. The
continuous transmission of data gives information near real-time on the
operator screen and an automatic alarm system, which can automatically
stop the operation of the installation, for example, if there utykanie
in stone. Wireless data transmission is possible, mainly by means of radio waves or acoustic signal.
The wireless transmission of the acoustic data.
Wireless data transmitter.
Using a wireless transmission from the probe to the surface provides the operator with a significant near-real-time information, and at the same time, work with equipment greatly facilitated the lack of cables. Transmitted in real time, data from the inclinometer can be used to deliver alarms and automatic stops pressing, for example, if the probe is buried in the rock.
There are two basic technologies for wireless data communication - via radio waves, and an acoustic signal. In both cases a combined transmitter and a battery compartment connected to the probe. The receiver is mounted on the rig with the encoder depth and usually connected to a laptop with recording software via the interface unit.
Acoustic data transmission.
The transmitter of sound is at the top of the transmitting device. It transmits audio signal through the steel rods to the receiving microphone which is in direct contact with them. The microphone is placed in a very strong shell, so that through him it was possible to produce indentation probe. Acoustic Transmitter can be used both on land and at sea.
Data transmission via radio waves.
Radio antenna mounted at the upper end of the transmitting device that emits in the microwave range through the hollow space of the drill rod. The receiver is located on the mast of a research setting. It is important that the receiver is located above and aligned with the rods in the hollow container was clean and dry.
|System calibration CPT probe
The system is intended for calibration of sensors on the cone resistance (Qc), side friction (fs) and pore pressure (u), located in the probe Geotech CPT NOVA
