The Soil Static Lateral Pressure Coefficient (K0), often referred to as the "at-rest" earth pressure coefficient, is a fundamental parameter in geotechnical design. It defines the ratio between horizontal and vertical effective stress in a soil mass that has not undergone lateral strain. Accuracy in determining K0 is vital for the design of retaining walls, basement structures, and deep foundation systems.
Our OEM manufacturing process integrates high-sensitivity pressure transducers and automated strain control. By utilizing CNC machining for test chambers, we ensure that the rigid boundary conditions required for K0 testing are met without compromise, delivering data that aligns with ASTM D4767 and BS 1377 standards.
Unlike standard triaxial tests, our advanced K0 apparatus features real-time volume compensation and digital logging. This provides an information gain advantage by eliminating the "manual calculation lag," allowing engineers to see the stress path evolution dynamically during the consolidation phase.
Located in the high-tech hub of Xi’an, our factory leverages a robust ecosystem of raw material suppliers and specialized logistics. This allows us to offer competitive pricelists without sacrificing the precision of our geotechnical instruments. By controlling the entire manufacturing vertical—from milling to electronic assembly—we ensure that every device bearing the "Xiya" trademark meets rigorous quality benchmarks.
With more than 15 years of civil engineering background, located in 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.
Zealchon specialize in civil engineering research and experimental apparatus; another is the semiconductor laser research and development. Our range includes soil testing instruments, bitumen testing instruments, and cement & concrete testing equipment.
The "Xiya" trademark was rated as a trademark of Shaanxi Province. Under the guidance of professors from Chang'an University and Xi'an University of Technology, we have developed professional core technology instruments. Some products fill gaps in similar instruments and have won ministerial and provincial awards.
In dense urban environments, K0 values are critical for predicting the impact of deep excavations on adjacent structures. Our instruments provide the high-resolution data needed for finite element modeling (FEM).
For large-span bridges, the lateral earth pressure on abutments dictates the long-term stability. Our K0 testing kits allow for on-site soil sample analysis with lab-grade precision.
Safety in mining requires understanding the lateral stress state of tailings. Our equipment is ruggedized for harsh environments and provides reliable continuous monitoring.
