DDJ30-6 Coarse grained Soil Electric Compaction Instrument Introduction: The DDJ type coarse-grained soil electric compaction instrument complies with the national standards of the People's Republic of China "Soil Test Code" GB/T 50123-2019 and the Ministry of Electric Power of the People's Republic of China "Test Code for Coarse grained Soil in Hydropower and Water Resources Engineering" DL/T5356-2006. This instrument is suitable for compaction testing of coarse-grained soil samples containing clayey soil with a maximum particle size of 60mm and no free drainage. The DDJ electric compaction instrument is a new product that has been upgraded and modified based on the original DDJ30-5B model. The original hollow hydraulic cylinder is improved and designed as a variable frequency motor gear transmission, with an empty core rack and pinion mechanism for gripping the hammer head. Accelerate the return speed without leakage, simplify the mechanism, and improve the compaction efficiency. Use a programmable controller to control the system's operation, touch screen to display and record the total number of hits. The photoelectric control adjusts the drop height of the hammer, automatically controls the number of compaction times, and tracks and controls the drop height of the hammer automatically for each compaction cycle. This instrument strikes uniformly and is easy to operate, making it an ideal testing instrument for conducting compaction tests on coarse-grained soil in various survey and design units, scientific research institutions, and colleges. characteristic: 1. This equipment is mainly suitable for the maximum dry density test of coarse-grained soil; 2. The hammer drop height can be adjusted arbitrarily, and the number of compaction times can be fully controlled automatically; 3. Equipped with automatic tracking function, fully automatic control of the hammer drop height to ensure that the hammer drop height is the same for each layer, with an error of ± 10mm Technical parameters: Model: DDJ30-6 Sample size: Φ 300X288mm Hammer mass: 15.5 kg; 35.2 kg Hammer base diameter: Φ 150mm Hammer drop height: 600 ± 10mm Compaction function: 591.9 KJ/m3; 2688.2 KJ/m3 Number of hits per layer: 1-99 times (any set number of hits) Hammer speed: 8 blows/min (can be customized according to user requirements) Installation height: ≥ 3.5m Installation area: 6 square meters
