Vibratory Compaction Hammer for Soil and Material Testing | Reliable and Efficient Equipment for Civil Engineering

📌 ZY-4 Vibratory Compaction Hammer Overview

The ZY-4 Vibratory Compaction Hammer is designed and manufactured according to the technical requirements of the Industry Standard of the People’s Republic of China: JTGE51-2009 «Testing Procedures for Stabilized Materials with Inorganic Binders in Highway Engineering.» It is specifically used for vibration molding of stabilized granular materials with inorganic binders. This equipment includes cylindrical specimens for testing unconfined compressive strength, indirect tensile strength, and compressive rebound modulus, as well as beam specimens for testing temperature shrinkage coefficient, drying shrinkage coefficient, flexural strength, and flexural rebound modulus.

Equipment Advantages

• High Compaction Density and Excellent Compaction Effect: After compaction, the specimens have high density, avoiding stone crushing and gradation destruction during the process, ensuring material stability and consistency.
• Adjustable Vibration Parameters: The equipment supports flexible adjustment of vibration frequency and vibration force, ensuring optimal compaction effect based on material requirements.
• Flexible Operation Parameter Settings: In addition to vibration frequency, static pressure and compaction time can also be freely adjusted based on different testing requirements to ensure ideal compaction each time.
• Precise Control System: The equipment uses imported inverters, providing high precision control to ensure stability and accuracy during the compaction process.
• Real-Time Monitoring of Compaction Displacement: The equipment is equipped with a compaction displacement display function, allowing real-time monitoring of the displacement data during the compaction process to further ensure testing accuracy.

The ZY-4 Vibratory Compaction Hammer is widely used in civil engineering, highway construction, and material testing fields, especially for compaction testing of inorganic binders and soil specimens. Through efficient vibratory compaction technology, the equipment ensures effective compaction for soil testing and other construction materials, ensuring their stability and reliability in practical engineering applications.

As one of the key tools in geotechnical testing, the ZY-4 Vibratory Compaction Hammer provides efficient compaction molding and testing functions, suitable for the compaction and testing of soil, inorganic binders, and other construction materials. With its precise control system and adjustable operation parameters, the equipment plays a crucial role in civil engineering and highway construction. The design ensures high-quality specimen manufacturing and provides reliable material performance data for various engineering projects.
