Excavation-free foundation pit forming device based on vibration liquefaction and construction method thereof
The invention discloses an excavation-free foundation pit forming device based on vibration liquefaction and a construction method of the excavation-free foundation pit forming device. The excavation-free foundation pit forming device comprises a rigid limiting piece which penetrates through liquefiable soil to be pressed into a hard soil layer below a foundation pit; the partition plates are pressed into the liquefiable soil and connected with the liquefiable soil through rigid limiting pieces, and closed annular structures are formed between the partition plates to surround the to-be-excavated liquefiable soil, so that the saturated sand foundation is divided into a plurality of independent partition cavities; the vibration device is inserted into the liquefiable soil of the independent separation cavity, and the vibration of the sand in the independent separation cavity is released, so that the soil body in the independent separation cavity is liquefied; and the pumping device is used for pumping out the liquefied soil to form the foundation pit. The construction method solves the engineering problems of poor safety, complex process, long construction period, large amount of transferred muck, high manufacturing cost and the like when the foundation pit is excavated in the sandy soil area, and has the characteristics of good safety, low construction cost, high efficiency, reusability of an assembled structure and small environmental pollution.
本发明公开了一种基于振动液化的免开挖基坑成型装置及其施工方法，装置包括刚性限位件，穿过可液化土压入到基坑下方的硬质土层中；隔板，压入到可液化土中并通过刚性限位件相连接，隔板之间形成闭合环形结构包围待开挖的可液化土，以将饱和砂土地基分隔成多个独立隔腔；振动装置，插入所述独立隔腔的可液化土中，对独立隔腔内的砂土释放振动使独立隔腔中的土体发生液化；泵吸装置，用于抽出液化土形成基坑。本发明解决了在砂性土地区开挖基坑面临的安全性差、工艺复杂、施工工期长、转运渣土量大、造价高等工程难题，具有安全性好，施工成本低效率高，装配式结构可重复使用，环境污染小的特点。
