Multifunctional pile foundation structure
A multifunctional pile foundation structure is characterized in that in a pile group structure of prestressed pipe piles with the pile diameter of 300-1000 mm, the pile foundation periphery and the pile distance are 8-30 m, the length of a water seepage prestressed pipe pile is 2-6 m larger than that of other pipe piles, water seepage holes with the hole diameter of 10-20 mm are formed along a pile body, and percolation cloth is attached to the outer sides of the water seepage holes; the pile ends of the water seepage prestressed pipe piles are sealed and welded through steel plates or provided with pile tips, and the ratio of the number of the water seepage prestressed pipe piles to the number of the conventional prestressed pipe piles is 1: 4-15. Compared with an existing pile foundation, the pile foundation not only has the bearing function of a common pile foundation, but also has the advantages that sludge with low foundation bearing capacity is drained and consolidated into mucky clay with high foundation bearing capacity and low water content, the foundation bearing capacity and pile side friction resistance are improved, the use amount of the pile foundation is reduced, and carbon emission is reduced.
一种具有多功能的桩基结构，其特征在于，在300‑1000mm桩径的预应力管桩的桩群结构中，在桩基四周和桩间距8‑30m，其中的渗水预应力管桩桩长超过其他管桩桩长2‑6m，沿桩身设置孔径为10‑20mm的渗水孔外侧贴渗滤布的渗水预应力管桩，渗水预应力管桩桩端用钢板封焊或设桩尖，渗水预应力管桩桩数与常规预应力管桩桩数比值为1∶4‑15。与现有桩基相比，除具有普通桩基的承载功能外，还具有将地基承载力低的淤泥排水固结为地基承载力高、含水量低的淤泥质黏土，提高地基承载力与桩侧摩阻力，减少桩基用量，减少碳排放。
