The invention relates to a brand new enclosure wall method suitable for foundation pit support engineering, in particular to a hexagonal special-shaped hollow concrete pile and steel sheet pile combined enclosure wall. According to the combined enclosure wall, hexagonal special-shaped hollow prefabricated reinforced concrete piles are directly implanted to serve as main components of the enclosure wall for resisting lateral water and soil pressure, steel sheet piles are implanted between the reinforced concrete piles to support soil between the piles, the combined enclosure wall is sealed through high-pressure grouting reinforcement, waterproof performance is enhanced, and therefore the complete enclosure wall is formed. And after foundation pit construction is completed, the concrete piles are used as reverse thrust supports, and the improved pulling machine is used for recycling the steel sheet piles. The novel combined enclosure wall is suitable for enclosure projects in various common soil layers, has the advantages of simple construction process, no special construction precision requirement, high working efficiency, low manufacturing cost, no mud pollution to the environment and the like, and belongs to a novel low-carbon and environment-friendly enclosure technology.
本发明是一种适用于基坑围护工程中的全新围护墙做法‑六边异形空心混凝土桩与钢板桩组合围护墙。这种组合围护墙是采用直接植入六边异形空心预制钢筋混凝土桩作为围护墙抗侧向水土压力的主构件，在钢筋混凝土桩间植入钢板桩支档桩间土，通过高压注浆加固使组合围护墙密封加强防水，如此形成完整的围护墙，基坑施工完成后利用混凝土桩作为反推支撑，用改进的起拔机回收钢板桩。这种新型组合围护墙适用于常见各类土层中的围护工程，具有施工工艺简单、无特殊的施工精度要求、工效高、造价低、无泥浆污染环境等优点，属于低碳、环保的围护新技术。
