Long spiral drilling grouting piles are an innovative foundation construction method widely used in engineering projects. This technique offers strong adaptability to geological conditions, fast pile formation, low noise pollution, and cost-effectiveness. 01. Reinforcement Cage Fabrication Based on.
The Geotechnical Engineering Bureau provides earthwork and foundation engineering services for the design and construction of Departmental projects statewide. The progression of explorations to obtain subsurface information is an integral part of this work. This information is generally provided.
Long spiral drilled cast-in-place piles generally use superfluid concrete, which has good flowability. Stones can suspend in the concrete without sinking, and there will be no segregation. It is easy to put it into a steel cage; (Superfluid concrete refers to concrete with a slump of 20-25cm) 2.
This specification covers requirements for drilled pier construction. It includes delivery, handling, and storage of the casing, excavation, soil test-ing, placing of concrete and reinforcing steel, and inspection. Drilled piers are sometimes called drilled shafts, caissons, or bored piles.
