Xi'an Zealchon Electronic Technology Co., Ltd. stands at the forefront of the geotechnical and civil engineering instrumentation sector. With a robust 15-year legacy, our headquarters in the Xi'an New Technology Industry Development Zone spans 7,500 square meters of state-of-the-art manufacturing and research space.
Specializing in Dynamic Plate Load Test (DPLT) procedures, we provide the global market with "Xiya" trademarked instruments, recognized for their precision in assessing the dynamic modulus of deformation (Evd) for soil and subgrade. Our collaboration with prestigious institutions like Changβan University and the Air Force Engineering University ensures that every piece of equipment we supply meets and exceeds international standards.
The Dynamic Plate Load Test (DPLT), often utilizing the Light Drop Weight Tester, has revolutionized subgrade quality control. Unlike traditional static tests that take hours, the DPLT offers a rapid, reliable assessment of the soil's load-bearing capacity in under three minutes.
Before initiating the procedure, the test surface must be leveled. Any loose material is removed to ensure the 300mm diameter loading plate makes full contact with the soil. This is critical for accurate stress distribution.
The apparatus consists of a loading device (10kg drop weight), a damping spring, and a loading plate equipped with an accelerometer. The sensor must be calibrated to detect the vertical settlement (s) resulting from the impact force.
The procedure involves three pre-loading drops to "seat" the plate, followed by three measurement drops. The weight is released from a fixed height, generating a defined impact stress of 0.1 MN/mΒ². The integrated electronic device captures the settlement curve for each pulse.
The Dynamic Modulus of Deformation (Evd) is calculated using the formula: Evd = 1.5 Γ r Γ Ο / s. Where r is the plate radius, Ο is the maximum impact stress, and s is the average settlement. Our Zealchon smart testers automate this calculation, providing instant digital readouts.
Testing completed in 2-3 minutes per point, allowing for hundreds of checks daily on high-speed rail embankments.
High-resolution accelerometers capture settlement data with micron-level accuracy, minimizing human error.
Bluetooth connectivity and GPS tagging enable real-time data mapping for project management.
As a leading Chinese manufacturer, Xi'an Zealchon leverages the world's most comprehensive industrial supply chain. Our facility is equipped with CNC machining centers, milling machines, and advanced argon arc welding stations. This vertical integration allows us to maintain a "Wholesale Pricelist" that is 30-40% more competitive than European counterparts without sacrificing technical integrity. We offer "China Speed" in logistics, ensuring that complex geotechnical equipment reaches your job site in record time.
Our DPLT instruments comply with ASTM E2835, German TP BF-StB Part B 8.3, and Chinese TB10102. Whether you are working on a desert highway in the Middle East or a railway in Southeast Asia, our equipment meets local regulatory requirements.
The future of subgrade testing lies in Autonomous Geotechnical Analysis. Xi'an Zealchon is currently developing AI-enhanced sensors that not only measure Evd but also predict soil moisture content and compaction density through multi-spectral data fusion.
The "Xiya" trademark was rated as a trademark of Shaanxi Province, representing top-tier technology in road, bridge, and geotechnical testing.
Under the guidance of professors from Chang'an University Highway College, we fill the gaps in domestic and international instrumentation.
Our machines are used worldwide by government agencies, commercial labs, and contractors who recognize our "Craftsman Spirit."
