86 101 116 131 Mazier Soil Sampler Collection Drilling Equipment

Mazier automatic core barrel;

The Automatic Mazier Core Barrel is designed for obtaining undisturbed core samples in very soft soils, such as sands, silts and marls.

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. It is available in 86mm, 101mm, 116mm, 131mm, 146mm hole diameter and can be used in conjunction with T2 series and T6 series core barrels which are more suitable for hard rocks.

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.

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.

101mm Single Rotary Triple Mazier Sampler For Sandstone And Soft Rock

M101 TC (Tungsten Carbide) Core Bits possess no as hard cutting media as diamond so have a limited range of application; they are a very cost effective choice for drilling softer unconsolidated formations and is applied primarily in geotechnical soil investigation or for core drilling in overburden layers that are composed mainly of clay, sand, gypsum or soft shale. The Forsun TC Core Bit’s crown is composed of a tough, wear resistant matrix body with tungsten carbide wear pads gauge protection.
