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.
Suitable for treating most foundations including gravel soil, sandy soil, silt soil, cohesive soil, collapsible loess, plain fill and miscellaneous fill.
Simple process and flexible equipment ensure fast construction. Compared with replacement and pile foundation, it features lower cost and shorter construction period.
Basically no cement or steel is consumed, reducing construction waste and material transportation, making it economical and green.
Equipped with crawler travel gear, it has good site adaptability and can work flexibly in mountainous areas, backfill areas and large-scale construction sites.
The reinforcement depth and effect can be precisely controlled by adjusting tamping energy, tamping point spacing and tamping times.
Foundation reinforcement for backfilled sites of factories, warehouses, residential buildings, etc., to eliminate uneven settlement.
Reinforcement of subgrades for highways, railways, airport runways and other traffic facilities.
Large-area foundation treatment for wharf yards, freight yards and logistics parks.
Backfilling in mining areas, site leveling and foundation reinforcement of old industrial plants.
Dike foundation reinforcement for dams, reservoir areas and flood control projects.
Reinforcement of complex foundations such as collapsible loess, soft fill and high-fill in mountainous areas.
