Pre-Operation Preparation
1. Equipment Inspection: Thoroughly inspect all equipment parameters and functions to ensure all systems are functioning properly. Check the hydraulic oil level and quality to ensure it is clean and sufficient.
2. Site Survey: Thoroughly remove debris such as rocks, metal parts, wood, and pipelines from the work area to prevent splashing injuries or damage to the equipment. Identify any pipelines beneath the work area and maintain a safe distance or implement protective measures.
3. Layer Thickness Control: Strictly control the thickness of each layer, typically 20-40 cm, determined through testing based on equipment capacity, soil quality, and design requirements.
Operation Precautions
1. Pressure and Frequency Adjustment: Adjust the hydraulic system pressure and compaction frequency based on the application requirements and soil type, and do not exceed the equipment's rated range.
2. Uniform Compaction: Ensure uniform compaction during the application process to avoid areas of over- or under-compaction. 3. Special Area Treatment: When approaching structures (walls, columns, pipes), tamp first away from the structure, then gradually approach. Control the tamping energy to avoid collisions and excessive vibration that could affect structural safety.
4. Path and Overlap: Use a linear, reciprocating or spiral motion from the outside inward, ensuring sufficient overlap between the front and back tamping marks and a close connection between the left and right tamping marks to eliminate missed tamping spots.
5. Avoid Operating on Hard Surfaces: Do not operate on concrete or other hard surfaces.
Safety Operating Prohibitions
1. Refueling or maintenance is strictly prohibited while the equipment is in operation.
2. Touching rotating or moving parts is strictly prohibited.
3. Operating on steep slopes or slippery, unstable surfaces is strictly prohibited.
4. Tamping frozen soil, extremely hard concrete blocks, or other objects that exceed the equipment's capacity is strictly prohibited.
