The invention relates to a brand new enclosure wall method suitable for foundation pit support engineering, in particular to a self-sinking concrete pile and steel sheet pile combined enclosure wall. According to the combined enclosure wall, prefabricated reinforced concrete piles are directly implanted to serve as a main component for resisting lateral water and soil pressure of the enclosure wall, steel sheet piles are implanted between the prefabricated reinforced concrete piles to support and block soil between the piles, sealing and water stopping of the combined enclosure wall are reinforced through high-pressure grouting, 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一自沉式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，在预制钢筋混凝土桩间植入钢板桩进行桩间土的支挡，通过高压注浆对组合围护墙的密封止水进行加强，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。
