Deep foundation pit excavation supporting device and supporting method suitable for sandy soil areas
The invention discloses a deep foundation pit excavation supporting device and supporting method suitable for sandy soil areas, and belongs to the technical field of deep foundation pit excavation supporting of municipal administration, house building and the like. The deep foundation pit excavation supporting device comprises a steel sheet pile and a machine head, wherein the steel sheet pile isof an integrally-formed hollow tubular structure, the bottom of the pipe wall of the steel sheet pile extends downwards to form a conical tip end, the steel sheet pile is detachably connected with themachine head, and a fixing clamp matched with the steel sheet pile and used for clamping and fixing the steel sheet pile is arranged on the machine head. By the adoption of the technical scheme, sandy soil of a sandy soil layer and a gravel layer can be effectively supported, meanwhile, pumping and draining can be directly conducted in areas rich in underground water, the well digging cost is reduced, and the direct engineering cost can be reduced.
本发明公开了一种适用于沙土地区的深基坑开挖支护装置及支护方法，属于市政、房建等深基坑开挖支护技术领域。本发明的深基坑开挖支护装置包括钢板桩和机头，所述钢板桩为一体成型的中空管状结构，其管壁底部向下延伸形成锥形尖端，钢板桩与机头可拆卸相连，且机头上设有与钢板桩相匹配的用于夹持固定钢板桩的固定夹。采用本发明的技术方案可以有效的对砂土层及砾石层沙土进行支护，同时对于地下水丰富的地区，还可以直接进行抽排，减少打井的费用，有利于降低直接工程造价。
