The invention discloses a foundation pit side wall frost heaving prevention method, and belongs to the technical field of building construction. The side wall of a foundation pit is provided with a water draining hole, the water draining hole is a metal pipe draining pipe, a water draining hole is formed in the metal pipe, the outer portion of the segment, inserted into the soil on the side wall of the foundation pit, of the metal pipe is wrapped with water filter gauze, the metal pipe is connected with a power cathode, a metal bar is connected with a power anode, the metal bar corresponds tothe metal pipe on the same side, the ground surface of the position, between the metal bar and the side wall of the foundation pit, of the upper portion of the foundation pit is provided with waterproof geotechnical cloth, the metal pipe is connected with the power cathode, the metal bar is connected with the power anode, the metal pipe and the metal bar are correspondingly mounted, water in soilcan be smoothly drained, and through a method of reducing the water containing amount in the soil, soil frost heaving damage to the side wall of the foundation pit can be prevented.
一种基坑侧壁防冻胀方法，属于建筑施工技术领域，所述基坑的侧壁设有泄水孔，所述泄水孔为金属管排水管，所述金属管上开设有排水孔，所述金属管插入基坑侧壁土体的一段外部包裹有滤水纱布，所述金属管与电源阴极相连，所述金属棒与电源阳极相连，所述金属棒与同侧的金属管对应设置，所述基坑上部于金属棒与基坑侧壁之间位置地表设有防水土工布。本发明通过设置金属管与电源负极相连，金属棒与电源正极相连，二者对应设置，使土中水份顺利排出，降低土体含水量的方法来防止基坑侧壁发生土体冻胀破坏。
