Miniature pile construction method suitable for highway soft soil roadbed reinforcing structure and reinforcing treatment
The invention discloses a soft foundation reinforcing structure suitable for highway subgrade engineering and a micro pile construction method for reinforcing treatment, a micro pile is composed of a steel floral tube, sand or gravel filled in the steel floral tube and a pile cap, the reinforcing structure forms a vertical drainage channel for filling the sand or gravel in the steel floral tube, and drainage consolidation of a soft soil layer is accelerated; all the micro piles are connected into a whole through reinforced concrete beams; a drainage sand cushion layer and a mattress layer are sequentially arranged on the upper portions of the micro piles. According to the reinforcing structure, conventional steel floral tubes are adopted for the micro piles, factory standardization customization is facilitated, the requirements for construction sites and construction machines are low, and the construction process is more convenient, safer and more reliable; compared with pipe piles, the miniature piles are small in diameter, disturbance to a soft soil layer is reduced in the pile pressing process, due to the vertical drainage channels, upper filling loads are converted into effective stress of soft soil, the shear strength of the soft soil is improved, the overall stability of a soft foundation in the upper embankment filling process is greatly improved, the early-stage embankment filling speed is increased, the construction period is shortened, and the construction period is shortened. And the manufacturing cost of a single pile is low.
本发明公开一种适用于公路路基工程中软基加固结构及加固处理的微型桩工法，微型桩由钢花管、钢花管中装砂或碎石和桩帽组成，加固结构为钢花管中装砂或碎石形成竖向排水通道，加速软土层排水固结；所有微型桩通过钢筋混凝土梁联结成整体；在微型桩上部依次设有排水砂垫层、褥垫层。本发明加固结构在于微型桩采用了常规钢花管便于工厂标准化定制，对施工场地、施工机械要求低，施工过程更便捷、安全可靠；与管桩相比，微型桩直径小，压桩过程中减少对软土层扰动，由于有竖向排水通道，上部填土荷载转化为软土有效应力，软土抗剪强度得到增长，大大增强软基在上部路堤填筑过程中的整体稳定性，加快前期路堤的填土速率，缩短工期，单根桩的造价低。
