SoilSoil Drilling & Sampling
Undisturbed Soil Sampling
This set for heterogeneous soils is used to carry out manual drilling and sampling in a great variety of different soils in an ergonomically sound way. It is particularly suitable for general soil investigation (description of the layering, geology, archeaology) as well as taking samples for such activities as environmental research.
Augerings and samplings in homogeneous soils, in almost all cases can be executed with one type of auger. For augerings in heterogeneous soils, several different auger types will be applied. This led to an auger set for heterogeneous soils. With the standard set it is possible to execute manual augering to a depth of 5 meter, without great physical effort.
Hand-operated Bailer Boring Equipment
The standard bailer boring auger set is suitable for augerings to a depth of about 7 meter. The set is very suitable for - in addition to exploratory soil augering and sampling - inserting monitoring well pipes for groundwater level measurements and for sampling.
The bailer, an essential part of the set, is a stainless steel tube with a stainless steel or synthetic valve on the lower part. By moving the bailer rapidly up and down loose material will collect in the bailer. In principle, this takes place below the tube where space is available. This allows the casing tubes to be pushed deeper into the ground. When turning in the casing tubes, the casing shoe with the slotted notches protects the lower tube and simplifies the turning in of the casing tubes. In order to protect the top tube a steel casing head is provided. For the protection of the screw thread during transport special thread protectors are supplied. The casing tube platforms are used in combination with the tube clamp. Bailing and driving in the casing tubes can be done in a more ergonomical way.
Lifting Sets for Drilling Equipment
The heavy lifting set is usually used in combination with heavier (hand- operated) drilling equipment for water wells. The tripod and the winch are used, among other things, for lowering and lifting drilling equipment (e.g. the bailer), or for removing the casing tubes.
The heavy lifting set is used:
· As a tool in performing deeper hand drillings or for drilling with heavier drilling equipment
· For removing casing tubes and lowering / lifting drilling equipment.
· For the installation of water wells and submersible pumps
· General hoisting activities
Soil Core Sampler
Hand-operated equipment can be applied for soil research up to a depth of 5 to 10 meter. The mutual quality of many gouge augers is that they all are fitted with an almost half-cylindrical operational part with parallel cutting edges running vertically, justifying the name gouge auger. This operational part may vary in length as well as in diameter. The most suitable length depends on the penetration resistance, the substance of the soil and the required boring depth. The longer the operational part the more vulnerable the auger is to torsion. The selection of the most suitable diameter depends on the composition and the structure of the soil and on the purpose of the research.
In general a smaller diameter is applied in soils with a fine and/or dense structure, by comparison to soils with a loose structure (for instance young swampy peat).
Soil Classification Sets
Soil research is a very important aspect in the planning and execution of agricultural- as well as civil engineering and operations. In order to make the soil research as comprehensive as possible the following studies must be made with regards to:
· the build up of a soil (i.e. determining the composition, the thickness and the position of the various strata);
· the soil properties (measuring the permeability, the filtration capacity, the bearing capacity, etc.).
The build up of a soil and strata is determined with the use of augers. The hand auger is generally used for not too deep bore-holes. Hand augers are extremely useful for soil research. Investigating the properties of a soil either takes place in situ, or in the laboratory with the aid of soil samples. For the execution of a universal soil classification in situ various articles have been included in our program.
Sampling Building Materials
The Building Materials (Soil and Surface Waters Protection) Decree for the Netherlands came into effect on 1 July 1999 for the use of stony materials and earth in construction and other works. The purpose of the Decree is to prevent the pollution of surface waters, groundwater and soil. Harmful substances leaching form stony building and other materials or contaminated earth can cause pollution. The Decree is in line with the general thinking on quality and quality control. It includes rules, regulations and standards which guarantee a specified quality of building materials, including earth.
Percussion Drilling/Hammer
Percussion gouges can be used to take reasonably undisturbed samples from depth to about 10 meters, without the use of drilling liquid (sample suitable for chemical analysis). Thanks to the special design the beating power of the percussion hammer is passed on in an optimal way to the percussion gouges, resulting in a higher drilling speed. The design also enables easy emptying and cleaning. Depending on the soil type, drilling depth and desired quantity of sample one of various gouge types is chosen.
Drilling Sets for Shallow Wells
Construction of a well must always be preceeded by a detailed survey of the area in order to find the most suitable location. Before starting fieldwork, as much information as possible regarding the hydrogeological situation should be collected from existing reports, maps, etc. It is also important to gather information about existing wells, hand dug holes or springs. The landscape features and certain types of vegetation also provide information about the geohydrological conditions in the area.
Casing Tubes and Accessories
The casing tubes have been fitted standard with left-hand screw thread. Drilling is usually a clockwise action, the casing tube threading must therefore be anti-clockwise. Otherwise the auger would loosen the casing tubes as soon as it gets stuck, which would then cause the loss of the casing tube or the casing shoe. The casing shoes are provided in two designs: one with slotted notches in particular for use in clay and with welded notches for other types of soil.
SonicSampDrill System
SonicSampDrill is a unique concept for drilling and sampling that is characterised by speed and quality while causing next to no inconvenience to its environment or disturbance of the soil. Eijkelkamp Agrisearch Equipment already has experience with the Sonic which was originally designed for seismic research since 1995. These days the advantages of the SonicSampDrill are also appreciated in geological and environmental technology. At the same time the Sonic's speed and quality make it increasingly attractive to - for example - the archaeological market. Obviously more possibilities are waiting to be discovered and developed. With the SonicSampDrill we can make sure that your opportunities in the market will take great strides when it comes to speed and quality.
