Mazier M101 mm Core Barrel, Taking Undisturbed Soil Sampler Equipment

Mazier automatic core barrel

This technology takes large diameter (101 mm) core samples in 1.5 m length pieces.

Using triple wall core barrel permits removal of the sample as it is taken from the ground, guaranteed the undisturbed sample of the core. Thats why these samples in addition good for large diameter geotechnical laboratory tests beyond geological purposes.

The third, inner tube made of plastic and continuously cover the sample.

Mazier Core Barrel Mazier core barrel shows shoe cutting projected in front of the core bit Mazier's automatic core barrel is designed to obtain undisturbed core samples in highly soft soils. This core barrel has a spring inner tube assembly. When drilling in soft formations, the lifting core case overhangs up to 50mm in front of the bit, and acts as a cutting shoe. The soft core is protected from water. When coring in harder materials, the spring inner tube is loaded under pressure and the inner tube retracts, so now the core case assumes a normal position. PVC coreliner is used inside the inner tube to maintain the core, and a "basket" catcher can be used to prevent soft materials from slipping out. This type of core barrel is widely used in parts of Europe and Australasia and is reported to provide 100% recovery in soft formations, such as sand, silt and marls. It is available in a hole diameter of 101mm (core 74mm) and can be used in conjunction with T2-101 and T6-101 core barrels which are more suitable for hard rocks. The 74 mm diameter core obtained with mazier is compatible with commonly used laboratory triaxial testing equipment.
