Verken Dormer Grondmonsters’ Hand Auger Solutions
Dormer Soil Samplers is a distinguished manufacturer specializing in hand auger soil sampling equipment, distributed across 97 lande.
Our product range encompasses several varieties of soil samplers, offering diameters from 50mm to 100mm, tailored to diverse soil conditions.
The fundamental open spiral augers are available in two primary sizes: 50mm en 62 mm, each with options of 1.0M or 1.5M in length, which can be attached to plain tubular extension rods for incremental soil sampling. Beyond the 1.5m mark, excessive friction hinders the feasibility of maintaining a continuous spiral.
Daarbenewens, we present a collection of ‘shell type’ grond samplers, incorporating a hollow tube design with various cutter styles optimized for distinct soil types. These come in nominal sizes of 50mm, 62mm, 75mm, en 100mm, with each ‘shell type’ sampler measuring 450mm in length.
These samplers are securely welded to a tubular shaft, available in lengths of 1.0M or 1.5M. This configuration ensures both operational comfort and facilitates seamless depth logging.
Within the ‘shell type’ category, the SOS model serves as a versatile, general-purpose soil sampler. The SA variant is designed for sand sampling, available in standard and Heavy Duty configurations to accommodate clean sand and sand with debris, respectively. For gravely soils, the SOD auger, known for its aggressive cutters, offers enhanced performance, although it may require more effort to operate.
The JA model, a compact, open-top sampler, is specifically designed for shallow soil sampling, suitable for depths of less than 1 meter. Our SP auger, 'n oop spiraalontwerp, is primarily intended for drilling holes or penetrating hard soil layers.
The minimum diameter of our samplers is governed by the diameter of our plain tubular extension rods, facilitating incremental sampling beyond the 1.0-meter sampler length.
These extension rods, constructed from lightweight 40mm diameter tubing, feature a male connecting thread at the bottom, aangevul met 'n ooreenstemmende vroulike draad aan die bokant. For your convenience, veerstaal Tommy Bars (breaker bars) are included to aid in disassembling threaded connections.
Stones or gravel often pose a significant challenge for hand-operated samplers, as the cutters are unable to effectively engage with these obstructions. Consequently, the stones must be displaced either inside or outside the sampler. In gruwelike gronde, the abundance of stones can cause the cutters to rebound, leading to erratic sampler movement and reduced penetration.
While a drill rig possesses the power to stabilize the auger and displace stones, manual operation lacks the precision required for this task. Selfs ons gemotoriseerde eenheid, die Drillmite, though potent, cannot entirely mitigate this issue, as human operators struggle to maintain stability when encountering stones.
Although it demands strength and persistence, manual operation can, at times, overcome these challenges. As alternatief, ons bied verskillende groottes Star Drill en Stone Catcher aanhegsels, designed to displace or pulverize stones as needed.
Many users prefer to relocate the borehole in the hope of bypassing stone encounters altogether.
In conclusion, Dormer Soil Samplers provides an extensive range of auger styles, each meticulously tailored to address specific soil conditions.
Our commitment to offering versatile solutions and comprehensive accessories, including various handle types (standaard geverfde staal of ratel), dra sakke, gereedskapkiste, en verlengstange (aluminum, staal, of vlekvrye staal), underscores our dedication to meeting your unique soil sampling needs.
