ZD-TS2 type triple tube single action sand extractor

ZD-TS2 type triple tube single action sand extractor

    

The inner ring knife sander was originally used to take sand soil that is difficult to prepare, and it can take eight 6.18x at a time. 2cm ( 30cm 2) Standard sample, and can be placed directly into the test instrument together with the ring cutter to meet the requirements of conventional bulk test such as bulk density, tree branching, compression and direct shearing. It has been promoted and applied by surveying units for many years, and the sampling range has been expanded to silt soil and even general soil layers. It has the advantages of convenient use, convenient soil opening, high sampling rate and good sampling quality. For user feedback information, ZD-TS2 triple-tube single-action sand extractor is suitable for slurry rotary drilling rigs (such as type 100, etc.) without hoisting hammer. The drilling sampling is completed once and has the following characteristics:

one. Except for pipes, residual soil pipes, pipe boots, alloy drill bits, bearings, and seals, all are made of stainless steel. Strong corrosion resistance and durability;

two. Drill hole diameter is small ( 108mm ) outer tube diameter 89mm There is a residual soil pipe, there is a Huff-type spacer ring between the inner ring cutters of the sample pipe, and a drop-proof earth ball valve is added, and the sampling rate is high;

three. Reduced beam boots improve sample quality. Pipe boots ahead, depending on the formation, during the sampling process -35mm

Automatically expand and contract within the range;

four. The ends of the sample tube are made of ABS engineering plastic and lined with a leak-proof sealing cushion, which does not need to be sealed and is convenient to use.

Instructions:

1. The bottom hole sampler is placed, connected to the active lever, water (slurry) pressurizing rotary drilling 35 -38cm (The mud particles should be small

in 1mm ). After stopping the drilling, open the ground return valve to lift to the ground;

2. Remove the outer tube with the drill bit, remove the tube shoe, and screw the cover after cutting;

3. Remove the sample tube, screw it on the cover, and put it into the special shockproof box to send it to the test room;

4. Remove the residual soil tube and clean the threaded part and reassemble the butter.
