The Slip Form method is a type of special hydraulic form of the existing on-site casting method. After pouring the concrete, when the strength of the concrete is greater than that for self-support, it moves upward and continuously repeats rebar assembly, concrete pouring, and curing to complete the structure. It is suitable for safety, shortened construction period, and high-quality structures.

applied area

Railroads and roads: vertical ventilation shafts, vertical stations Power and communication facilities: vertical power conduit Underground storage facilities: downtown waterway vertical shaft, pumped storage power generation and dam vertical shaft Bridge piers (PIER): long bridge piers, large bridge pylons, etc. SILO: Storage of cement, grain, gas, raw materials Stack (Chimney, STACK): Applied to plant facilities, power plants, and buildings High-rise building: High-rise building CORE (E.V.. staircase, vertical wall) Port pier: CAISSON

Features of construction method

1. High-quality finishing of circular walls and internal walls with continuous rise of NEO slip form 2. Excellent construction period reduction due to simultaneous rebar assembly, concrete pouring, and curing processes (weekly: 1.5~2.0m/day) 3. Air saving through PC SLAB and PC stair assembly methods 4. Ensure worker stability with 3-tiered indoor work space 5. Applicable to construction even in narrow field locations in urban areas 6. The higher the construction height, the better the construction period and cost.
