Construction method of static drilling root planting drainage pile
The invention discloses a construction method of a static drilling root planting drainage pile. Drainage plates are fixed around the prefabricated pipe pile while the pile is sunk, the prefabricated pipe pile and the drainage plates are brought into a foundation together, the layout of vertical drainage channels around the pile is completed, and the construction operation is convenient; a drainage pipeline is sealed by connecting the drainage plates with a ground vacuum pump; vacuum pumping and drainage are conducted through the vacuum pump, so that the water content of cement soil around the pile is rapidly reduced, the cement curing speed is increased, the cement soil strength increasing period is shortened, and the bearing capacity and stability of the prefabricated pipe pile are guaranteed; and vacuum negative pressure is favorable for accelerating drainage consolidation of soil around the pile and improving the strength and rigidity of the soil, so that the side friction resistance of the pile is improved, and the bearing capacity and deformation resistance of a pile foundation are enhanced. According to the construction method, the operation modes that the drainage plates are arranged around the pile to form the drainage channels and vacuum negative pressure is combined to accelerate the drainage consolidation of the soil around the pile and improve the side friction resistance and the bearing capacity of the pile foundation can also be applied to other pile planting construction.
本发明公开了一种静钻根植排水桩的施工方法，在沉桩的同时在预制管桩的桩周固定排水板，将预制管桩和排水板一并带入地基，完成桩周竖向排水通道的布设，施工操作便捷；通过将排水板与地表真空泵相连接，完成排水管路密封；通过真空泵抽真空排水，快速减少桩周水泥土的含水率，加快水泥固化速度，缩短水泥土强度增长周期，保证预制管桩的承载能力和稳定性；真空负压有利于桩周土体加快排水固结，提高土体强度和刚度，由此提升桩侧摩阻力，强化桩基承载力和抗变形能力；本发明采用的在桩周设置排水板形成排水通道及结合真空负压，以加速桩周土体排水固结，并提高侧摩阻力和桩基承载力的操作方式也可以应用于其它植桩施工中。
