Scope

Main technical content: 1. Low-pile foundation projects for industrial and civil buildings and structures in areas with a seismic fortification intensity of 7 or lower. Railway, highway, bridge, water conservancy, and municipal projects can also use low-pile foundations under the same technical conditions. 2. Enhanced pipe piles can meet the durability requirements in different corrosive environments. High-strength anti-corrosive concrete enhanced pipe piles are suitable for strong corrosive environments; high-strength and ultra-high-strength concrete enhanced pipe piles are suitable for medium and weak corrosive environments. 3. The enhanced pipe piles in this collection are mainly used in pile foundation projects that can withstand vertical compressive loads and vertical uplift loads. When simultaneously subjected to horizontal loads and earthquake effects, designers should conduct additional design checks based on the single-pile design bearing capacity and pile reinforcement structure, combined with geological conditions and engineering experience, and select them after comprehensive consideration. 4. Enhanced pipe piles are divided into Types I, II, III, and IV according to the effective pre-compression stress of concrete and the bending performance of the pile body. Among them, the 300mm-diameter enhanced pipe piles, Type I enhanced pipe piles, and thin-walled high-strength concrete enhanced pipe piles are only suitable for foundation treatment and temporary facility foundations.
