Triefus Triple Tube Core Barrels        
            

Triefus Triple Tube Core Barrels designed for dam sites , bridges , building , well mineral recources core drilling 
                                                                                                            
Triefus Triple Tube Core Barrels is a precision instrument designed for dam sites, bridges, building, well mineral recources core drilling 

 

 

The Triefus Triple Tube Core Barrel is a precision instrument designed to maximize core recovery in site investigation and exploratory drilling programs. With this cafe barrel it is possible to obtain as near to 100% volumetric core recovery in as undisturbed condition as it is possible to achieve with rotary core drilling equipment. It is not uncommon for drillers to report 98% + core recovery in the most difficult formations.

 

 

The results obtained from the use of Triefus Triple Tube Core Barrels can be a deciding factor in the investment of large sums of money in areas such as foundation design for dam sites, bridges and building, as well as the development of mineral resources. These results must be as accurate as it is possible to obtain. Triefus Triple Tube Core Barrels are capable of giving these results even under the most adverse circumstances provided they are used with the care that their function demands.

 

When used in conjunction with the Triefus Borehole Impression Device, it is possible to orient the core, differentiate drilling fractures from natural bedding planes and precisely locate the position of any core loss. An easily transportable permanent record of cored borings is also available for laboratory use.

 

In addition to the standard Triefus Triple Tube Core Barrel a retractor model is available in most sizes for coring very soft formations where the core may be washed away by any excess jetting action while circulating. Many parts are interchangeable between both types of barrels and the retractor barrel can be converted to a standard barrel on site. 

 

 

Triple Tube Core Barrels (Standard)

 

The Triefus Triple Tube Core Barrel, as described in figure 1, was developed nearly sixty years ago in conjunction with the snowy mountains hydro electric authority and the joint coal board of Australia for coring the badly weathered and decomposed granite in south eastern new south wales ‘from the grass roots down’.

The cutting sizes AMLC, BMLC, NMLC and HMLC are to international standards and are used with standard W series casing. Water Ends are threaded to accept W series drill rods. From 2C to 8C the barrels are supplied with rod connections specified by the client.

 

The letters ‘LC’ used in the reference nomenclature refer to ‘Large core’ to differentiate between the original double tube core barrels (NM etc.) in which the core diameter was much smaller than that obtainable with these barrels.

 

All Triefus Triple Core Barrles are normally supplied with steel split inner tubes; however plastic (non-split) inner tube is available in NMLC size and stainless and hard chromed split tubes can be supplied for most other sizes. The plastic inner tube is used in NMLC triple tube core barrels where it is desired to retain the core exactly as it is recovered from the hole. The core is not removed from the plastic inner tube which is sealed at each end and despatched undisturbed to the laboratory. Because the plastic is clear and only 1 mm thick, visual examination of the core is possible at the drill site.

 

The outer tubes of all Triefus Triple Tube Core Barrels are hard faced at each end. Staggered hard facing over the full length of the outer tube can be supplied if required.
