The invention discloses a foundation drainage method and system. The foundation drainage method comprises the following steps that a vertical drainage main pipe internally provided with a plurality of separation layers and a plurality of water pumping sub-pipes is implanted into a foundation; the top end and the upper side wall of the drainage main pipe are closed, and a plurality of filter holes are formed in the lower side wall of the drainage main pipe; the depth arrangement of the separation layers is adjusted, and a multi-layer drainage cavity is formed; the water pumping sub-pipes are inserted into the drainage cavity; and the foundation is drained through the water pumping sub-pipes. According to the foundation drainage method and system, accurate layered vacuum air pumping drainage can be conducted on all layers of soil according to the soil layer permeability coefficient difference, the soil displacement of the soil with the poor permeability coefficient is increased, the drainage time of the soil layer is prolonged, a traditional vacuum precipitation mode construction method is replaced, the well diameter is increased, the precipitation path is shortened, and the deep soft soil precipitation effect is improved.
本发明公开了一种地基排水方法及系统。根据本发明实施例的地基排水方法包括以下步骤：在地基中植入内部设置有多层分隔层及多个抽水子管的竖向排水母管；所述排水母管的顶端和上部侧壁封闭，下部侧壁形成有多个滤孔；调整所述分隔层的深度布置，形成多层排水腔体；将所述抽水子管插入所述排水腔体中；以及通过所述抽水子管对所述地基进行排水。根据本发明实施例的地基排水方法及系统可根据土层渗透系数差异，对各层土体进行精准分层真空抽气排水，加大渗透系数差的土体排气量、延长该土层的排水时间，替代传统的真空降水方式工法，增大井径、缩短降水途径，提高深层软土降水效果。
