Equipment for Standard Penetration Split Barrel Soil Sampler SPT Sampler Split Spoon SPT Sampler Split Spoon Sampler Standard Penetration Test (SPT) Standard Penetration Test Sampler Standard Penetration Test (SPT) Sampler for Geotechnical Sampling, Split Tube Sampler to perform the Standard Penetration Test (SPT) by BS 1377: Part 9: 1990. Working together are an Auto Trip Hammer, SPT Drive Rods, and a Split Tube Sampler. SPT: STANDARD PENETRATION TEST The Standard Penetration Test is used to determine the engineering characteristics of soil layers and soil stratification. Split barrel samplers were employed to collect disturbed and undisturbed samples during the SPT, which were then put through additional laboratory tests. For identification purposes and for laboratory tests that permit the use of disturbed samples, the in-situ penetration test delivers a soil sample. The method of sampling soil entails using a split barrel sampler to collect a representative, disturbed model and test the subsoil's resistance to standard sampler penetration at the same time. The amount of blows necessary to drive a steel tube with specific dimensions into the subsoil to a specific depth with a hammer of specific weight (mass) is how many times the resistance to penetration is measured. A boring log data sheet must contain all relevant sample data, penetration resistance, and borehole data. Reporting should include the depths at the top and bottom of each 150-mm segment of sampler penetration as well as the number of blows necessary to impact that segment of penetration. The following crucial procedures are taken in collecting the data from the SPT, N value: ­ preliminary test ­ number of blows for the sampler penetration range of 0 to 150 mm; ­ actual test ­ number of blows for the sampler penetration range of 150 to 300 mm and 300 to 450 mm. An automatic hydraulic SPT device was installed on the drill mast side for simple placement over the SPT rods. Drop stroke of 760 mm, drop weight of 65 kg, and control panel display of blows. Description of goods: For performing the Standard Penetration Test (SPT), use the SPT Split Tube Sampler. We produce it in compliance with BS 1377: Part 9: 1990. A complete set of SPT samplers includes a Top ball valve Adaptor, two Split Spoons, and an open SPT Shoe. There are basket retainers made of steel and plastic. When the sampler is removed from the borehole, the ball valve adaptor prevents the sample from being washed out of the sampler. There are other options for a 60-degree nose cone and a long solid rod with a 60-degree point. The type of drill rods used to drive the sampler will determine the screw connection on the top adaptor, however, 1.1/2" BW or AW Rod is most typically utilised. Specifications: The dimensions of the typical split tube sampler are 2" (50.8 mm) OD x 1.3/8" (34.9 mm) ID x 18" (457 mm) or 24" (610 mm) length.

Use: For approximately 100% core recovery, the Triple Tube Core Barrel is utilized for mineral research, geotechnical study, diamond core drilling, soil analysis, testing of high-rise construction foundations, and exploration of dams and bridges. Method: The reaming shell, diamond core bit, and core lifter casing are taken out once the triple tube barrel has been taken out of the drill hole. The third, or split tube, is forced out using a piston mechanism after air or water is poured into the head. The top half of the split tube is then raised, showing the core in its original state. RDS Engineering manufactures the following Triple Tube Core barrels: • BMLC Triple Tube Core Barrel • NMLC Triple Tube Core Barrel • HMLC Triple Tube Core Barrel Specification and standard size: NMLC Triple Tube Core Barrel core diameter of 48 mm and a Drilling hole diameter of 76 mm.

RDS Engineering manufactures diamond Reaming shells for NMLC triple tube for Diamond Core Drilling, Tunnel Drilling, Geotechnical Investigation, Soil Testing, Drainage, and Grouting of Holes, among other uses. The reaming shell, which is immediately above the diamond core bit, keeps the drill hole's outer diameter constant. The diamond core bit is joined to the core barrel by the diamond reaming shell. The reaming shell effectively reams the hole because its outer diameter is only a little bit larger than the core bits. The reaming shell serves as a link between the core bit and the outer barrel and is a crucial component of a diamond drilling system. In addition to stabilizing the drill string's bottom, it reams the hole to the right size. The drilling crew should regularly inspect the reaming shell's outer diameter since a worn-out or smaller reaming shell will cause the drill bit and drill string to become stuck. RDS manufactures great-quality synthetic and natural diamonds that are placed in a matrix with great resistance and is used to create reaming shells. On the leading edges of the ring, friction-resistant tungsten carbide inlays offer extra security and a longer lifespan.

RDS Engineering manufactures a full line of double tube core barrels in accordance with ISO Standards and DCDMA. Use: Double tube core barrels are used for a variety of purposes, including diamond core drilling, tunnel drilling, geotechnical analysis, soil testing, drainage, and grouting holes. Method: The inner tube is connected to the core barrel head by bearings in double tube core barrels, which allows the inner tube to rotate independently of the core barrel. The outer tube and inner tube of the double tube core barrel are filled with water. The inner tube bottom end has perforations that allow water to pass through. The only part of the core that is prone to corrosion is up to the diamond core bit. In relation to the overall length of the two tube core barrel, this distance is quite short. It is conceivable to accept a core made of softer and fractured materials once the erosion issue has been resolved. It delivers an improved rate of core recovery and little core erosion. Specification and standard size: AX double tube core barrel core diameter of 30.1 mm and a Drilling hole diameter of 48 mm. BX double tube core barrel core diameter of 42 mm and a Drilling hole diameter of 60 mm. NX double tube core barrel core diameter of 54 mm and a Drilling hole diameter of 76 mm.
