Road foundation protection system of deep soft foundation and construction method of road foundation protection system
The invention discloses a road foundation protection system for a deep soft foundation, which is characterized in that a fill roadbed is arranged on the ground surface of a road, and the deep soft foundation is arranged between the ground surface and a stable ground surface; a plurality of rigid piles perpendicular to the ground surface are arranged downwards from the ground surface in the range of the bottom of the fill roadbed; and the lower end of the rigid pile penetrates into the stable ground by not less than 50cm. By the adoption of the technical scheme, additional stress is transmitted to the rigid piles and transmitted to the stable stratum of the base through the rigid piles, the masonry utilization rate is increased, the arrangement distance of the rigid piles is increased, and the number of the rigid piles is reduced; the bearing capacity of a deep soft foundation can be effectively improved, and the problem of road settlement of the soft foundation is solved; as the pile end of the rigid pile enters a relatively hard soil layer, the pile body is not compressed, the settlement is easy to guarantee, and the construction is rapid; the maintenance period is not needed after pile sinking, the foundation construction time can be greatly shortened, the construction efficiency is improved, and the project progress is accelerated.
本发明公开了一种深层软弱地基的道路基础防护体系，道路在地表面上设置填方路基，地表面向下直至稳定地层面之间为深层软弱地基；在填方路基底部的范围内，从地表面开始向下，设置多个垂直于地表面的刚性桩；刚性桩的下端，深入到稳定地层面下不小于50cm。采用上述技术方案，将附加应力传递至刚性桩上，由刚性桩传递至基底稳定地层中，既提高了圬工的利用率，增大刚性桩的设置间距，减少了刚性桩数量；可以有效提高深层软弱基底的承载力，解决了软弱地基的道路沉降问题；由于刚性桩桩端进入相对较硬土层、桩身不被压缩，沉降容易保证，施工迅速；沉桩后无需养护周期，能够大大减少基础施工时间，提高施工效率，加快了工程进度。
