Standard Practice for Using Hollow-Stem Augers for Geotechnical
Exploration and Soil Sampling
Standard Test Method for Standard Penetration Test (SPT) and
Split-Barrel Sampling of Soils
A well built, quality-crafted heavy-duty split tube sampler can be
found in stock at Diedrich Drill. Our 2" O.D. split- spoons are
heat treated for longer wear.
The complete sampler includes a durable head, a split- section
crafted of the finest quality 4130 steel and a heat treated show.
The Diedrich Drill sampler is manufactured in a 2", 2-1/2", or 3"
diameter size, and is available with the standard fine thread(8
threads per inch) shoe or a quick thread(4 threads per inch) shoe.
Our full line of accessories for the spilt tube samplers includes
steel and synthetic basket retainers, flap valves, and liners.
Standard Penetration Test (SPT) Sampler
Take the soil
The Standard Penetration Test (SPT) Sampler is used to lift the
lower soil test soil as a sample to understand its nature. In order
to make more understanding of the nature of the grassroots, it is
sometimes necessary to take the original soil in the depths, which
we call Standard Penetration Test (SPT) Sampler.
Brief overview
The Standard Penetration Test (SPT) Sampler is used to lift the
lower soil test soil as a sample to understand its nature. In order
to make more understanding of the nature of the grassroots, it is
sometimes necessary to take the original soil in the depths, which
we call Standard Penetration Test (SPT) Sampler.
Instructions for use:
Will take the soil ring shoe(casing shoe) drilled into the soil to
the depth of the need to remove the excavator, after the ring
casing shoe and semi-cylinder removed, with a scraper will take the
soil at both ends of the excess soil scraping to repair, then take
the soil within the ring Just 50 ml, the ring casing shoe soil can
be used as a test pattern.
The Standard Penetration Test (SPT) Sampler used in the project is
a ring casing shoe
Ring casing shoe is used to take the original soil is to do bulk
density (soil density), compression, shear and penetration tests
are essential to a commonly used instrument.
Mainly used to determine the compaction of the soil (1) the use of
ring casing shoe and precautions
When used to shoe blade down, in the cut soil samples to avoid
skew, so that the vertical force under the cutting, before using
the ring casing shoe can apply a little Vaseline. After use, the
ring casing shoe should be scrubbed and coated with some protective
oil, to prevent rust.
(2) check the ring casing shoe
The ring casing shoe is calibrated at least once a year and its
volume and quality are determined.
The inner diameter of the ring casing shoe shall be measured with a
caliper and shall be rotated at least three diameters, accurate to
0.1 mm, and the maximum difference shall not exceed 1% of the
standard value.
The quality of the ring casing shoe need to use 0.01g balance of
the balance, accurate to 0.01g
The Standard Penetration Test (SPT) Sampler for archaeological use
Standard Penetration Test (SPT) Sampler, hence the name of
thinking, take the soil, is an archaeological tool. The above link
(thread) archaeological tool probe rod, available underground at
any point of soil used to observe. Through the observation and
detection of soil, can distinguish between the existence of
antiquity literature.
Take the focus of the Standard Penetration Test (SPT) Sampler
For the requirements of the structure of the Standard Penetration
Test (SPT) Sampler, cattle Ben proposed to take the soil must
ensure that the soil smoothly down to the bottom of the hole, into
the soil, to minimize frictional resistance; to prevent the soil
before the waste into the liner, and affect the original degree of
soil samples; The earth to have a reliable sealing performance;
structure should be simple, easy processing and operation. ① the
top of the soil sample by the suction; ② soil sample at the bottom
of the suction; ③ soil into the soil method and depth.
The role of the Standard Penetration Test (SPT) Sampler and the
sampling method in the engineering geological survey is very large.
For different stratigraphic conditions, if you can choose the
appropriate soil into the process, the resistance was significantly
reduced. It is of great benefit to improve the rate of soil samples
and take quality by entering soil Standard Penetration Test (SPT)
Sampler and sampling methods.
