Characteristics and Applications of Dynamic Compaction Machines
YTQH series professional dynamic compaction machine with full rotation and multi section truss arm combination. This model has the characteristics of high efficiency, high reliability, and intelligent operation, which can meet the needs of most compaction construction. Widely applicable to dynamic compaction construction operations for foundation reinforcement treatment of industrial and civil buildings, warehouses, roadbeds, airports, and docks.
Remarkable reinforcement effect
By dropping heavy tamps freely from a height, strong impact and vibration are applied to the foundation, improving bearing capacity, reducing compressibility and minimizing settlement.
Wide application range
Suitable for treating most foundations including gravel soil, sandy soil, silt soil, cohesive soil, collapsible loess, plain fill and miscellaneous fill.
High construction efficiency & low cost
Simple process and flexible equipment ensure fast construction. Compared with replacement and pile foundation, it features lower cost and shorter construction period.
Energy-saving & eco-friendly
Basically no cement or steel is consumed, reducing construction waste and material transportation, making it economical and green.
Strong equipment adaptability
Equipped with crawler travel gear, it has good site adaptability and can work flexibly in mountainous areas, backfill areas and large-scale construction sites.
Controllable quality
The reinforcement depth and effect can be precisely controlled by adjusting tamping energy, tamping point spacing and tamping times.
Main Application Fields
Industrial & Civil Construction
Foundation reinforcement for backfilled sites of factories, warehouses, residential buildings, etc., to eliminate uneven settlement.
Road & Traffic Engineering
Reinforcement of subgrades for highways, railways, airport runways and other traffic facilities.
Port & Yard Engineering
Large-area foundation treatment for wharf yards, freight yards and logistics parks.
Mining & Plant Reconstruction
Backfilling in mining areas, site leveling and foundation reinforcement of old industrial plants.
Water Conservancy Engineering
Dike foundation reinforcement for dams, reservoir areas and flood control projects.
Special Foundation Treatment
Reinforcement of complex foundations such as collapsible loess, soft fill and high-fill in mountainous areas.
