我国南方一些地区,暗沟、暗塘较多,需要用砂石换土。当进行地基处理时,如果地下水位高,不宜采用蛙式打夯机加固,可采用插入式振动器施工。具体做法是,将基槽挖至槽底土层,停止抽水,搭起临时脚手架,小斗车直接把按比例和好的砂石从脚手架上倒入坑中拉平,每层厚度约为50厘米,当砂石中的含水达到饱和状态时,即可用插入式振动器按振捣混凝土的方 In some areas of southern China, there are more dark trenches and dark ponds, which need to be replaced with sandstone. When the ground treatment is performed, if the groundwater level is high, it is not suitable to use a frog type ramming machine for reinforcement. An insert type vibrator can be used for construction. The specific approach is to dig the foundation trench to the bottom soil layer, stop the pumping, erect temporary scaffolding, and the small bucket car directly straightens the proportioned and good sandstone from the scaffold into the pit, and the thickness of each layer is about 50 centimeters. When the water content in the gravel reaches a saturated state, the vibrating concrete can be vibrated with a plug-in vibrator.
