Accurate Soil Shear Strength MeasurementThis apparatus enables precise measurement of soil shear parameters using a robust, mild steel frame and a high-quality gunmetal shear box. Supporting various test speeds and specimen sizes, it ensures consistency and reliability in laboratory soil analysis, crucial for civil and geotechnical projects.
Reliable and Safe Laboratory UseDesigned with overload protection, mechanical safety stops, and corrosion resistance, the Direct Shear Apparatus offers safe operation even at higher load ranges. Its ergonomic manual controls and smooth gear-driven movement guarantee dependable functionality, suitable for bench top laboratory mounting.
FAQs of Direct Shear Apparatus:
Q: How does the Direct Shear Apparatus measure soil shear strength parameters?
A: The apparatus uses a dead weight loading lever system to apply force to a soil specimen within a gunmetal shear box. Shear force is measured with an external proving ring (not supplied as standard), enabling determination of soil shear strength under controlled laboratory conditions.
Q: What materials are used in the construction of the apparatus and why are they chosen?
A: The frame is made from powder-coated mild steel for durability and corrosion resistance, while the shear box is constructed from gunmetal to ensure dimensional stability and minimal friction, ensuring accurate test results and long-term usage.
Q: When should I use the Direct Shear Apparatus in a laboratory setting?
A: It should be used during soil mechanics laboratory testing, particularly when determining shear strength parameters is necessary for foundation design, slope stability studies, or any geotechnical investigation.
Q: Where should the Direct Shear Apparatus be installed and operated?
A: The apparatus is intended for indoor laboratory use, mounted on a bench top. Ensure the environment remains within an ambient temperature range of 5C to 40C with standard electrical supply (220-240V, 50 Hz).
Q: What is the process for conducting a direct shear test using this equipment?
A: First, prepare a single specimen (60mm x 60mm x 25mm) using the provided tray and place it in the shear box. Apply a vertical load using the dead weight lever, then advance the shear box at the selected speed using the worm gear drive, measuring displacement and force via dial gauge and proving ring (not supplied).
Q: What are the key benefits of using this Direct Shear Apparatus in soil testing?
A: The main benefits include high accuracy (1% F.S.), ease of manual control, reliable safety features, user-friendly specimen preparation, consistent test conditions, and a rugged construction that ensures long operational life and reliability in laboratory environments.
Q: How many specimens can be tested at one time and what are the specimen dimensions?
A: This apparatus is designed to test one specimen at a time, with standard specimen dimensions of 60 mm x 60 mm x 25 mm as required by the shear boxs internal measurements.
