Mazier core barrel function description

1. This Mazier core barrel has a spring-loaded inner tube assembly. When drilling in soft formations, the core lifter case protrudes up to 50mm in front of the bit, and acts as a cutting shoe. The soft core is protected from the water flush (see Figure a).

2. When coring in harder materials, the spring loaded inner tube comes under pressure and the inner tube retracts, so now the core lifter case assumes a normal position (see Figure b).

3. A PVC coreliner is used inside the inner tube to retain the core, and a “basket” catcher can be used to prevent soft materials from slipping out.

Applications:

The automatic Mazier core barrel is designed for obtaining undisturbed core samples in very soft soils.

2. It is available in 101mm hole diameter (74mm core) and can be used in conjunction with T2-101 and T6-101 core barrels which are more suited for hard rocks.

3. The 74 mm diameter core obtained with the mazier is compatible with the commonly used laboratory triaxial testing apparatus.


Advantages:

1. Undisturbed core samples from soft soil 0.1MPa
