In the realm of geotechnical engineering, determining the undrained shear strength of soft, saturated cohesive soils is paramount for the stability of infrastructures. The Vane Shear Test (VST), often referred to as the "avane shear test procedure" in specific industrial procurement contexts, represents the gold standard for in-situ testing. This procedure provides critical data that laboratory tests might fail to capture due to sample disturbance.
Currently, the global construction market is witnessing a surge in high-rise buildings and massive transport hubs built on reclaimed land or soft clay deposits. From the coastal developments in Southeast Asia to the expansive transport networks in North America, the demand for high-accuracy shear strength data has never been higher. Standardized procedures such as ASTM D2573 have become the universal language for engineers across borders, ensuring that a "High-Quality" test in Xi'an meets the stringent requirements of a project in London or Dubai.
The technical roadmap for shear testing instruments is moving rapidly towards Digitalization and Real-time Analytics. We are transitioning from manual torque measurement to wireless, high-precision electronic transducers.
With more than 15 years of civil engineering background, located in the new technology industry development zone in Xi'an, an ancient city in China. It covers an area of 7500 square meters of building area.
We manufacture and supply testing instruments for civil engineering, geological survey, water conservancy and hydropower, roads and bridges, highways, railways, and airports. We specialize in the production and sales of geotechnical testing instruments, asphalt and asphalt mixture testing instruments, cement and concrete testing instruments.
Zealchon is engaged in manufacturing and supplying a qualitative array of research and laboratory testing equipment. Zealchen specialize in civil engineering research and experimental apparatus; another is the semiconductor laser research and development.
Our workshop features machining centers, CNC lathes, and advanced welding (Argon Arc) technologies. This vertical integration ensures every "Vane" in our shear test kits is balanced to micron-level perfection.
Located in Xi'an, a central hub of the "Belt and Road Initiative," we offer unparalleled logistics efficiency, reducing lead times for global suppliers by up to 30% compared to coastal regions.
Following the "Xiya" trademark standard, rated as a trademark of Shaanxi Province, our products undergo rigorous stress testing before shipment, filling gaps in the international market for high-durability sensors.
The Vane Shear Test procedure varies slightly based on local geological conditions. Our equipment comes with pre-set configurations for:
Compliance is the bedrock of our service. We provide equipment calibrated according to:
• ASTM D2573 (Standard Test Method for Field Vane Shear Test)
• BS 1377-9 (British Standards for Soils for Civil Engineering)
• Eurocode 7 (Geotechnical Design)
Under the guidance of professors from Chang'an University Highway College and Xi'an University of Technology, we have developed a series of core technology testing instruments. Our research team consists of experts from top polytechnic universities, ensuring we hold the top technology in this expertise.
Standard procedures generally recommend a rate of 0.1° per second (6° per minute). This slow, steady rotation ensures that the undrained conditions are maintained within the clay, providing a true measurement of cohesive strength.
By leveraging the expertise of Chang'an University researchers and maintaining a 15-year manufacturing record, we provide "Expertise" and "Experience." Our "Authoritativeness" comes from our provincial trademark status, and "Trustworthiness" is built through our 'Three Guarantees' policy on all sold products.
Yes. We provide tiered pricing for distributors, government labs, and commercial testing facilities. Please contact our sales team for the latest 2024 industrial pricelist.
We recommend annual calibration against a certified standard. Our devices are designed with craftsman spirit to minimize mechanical friction, ensuring long-term reliability even in harsh field conditions.
