Water-rich sand layer open caisson construction method
The invention discloses a water-rich sand layer open caisson construction method, and relates to the technical field of building construction. The construction method comprises the steps of construction preparation, foundation pit excavation, precipitation well construction, cushion layer construction, steel bar binding and formwork erecting and disassembling, scaffold construction, concrete pouring, well wall reserved hole treatment, open caisson sinking, steel sheet pile construction, open caisson bottom sealing and bottom plate construction. According to the water-rich sand layer open caisson construction method disclosed by the invention, previous underground operation is converted into overground operation, so that less labor is used, and the labor intensity is reduced; in the construction method, the open caisson manufacturing and sinking process is direct and simple, and measurement and monitoring are more convenient; according to the construction method, common manual operation is replaced with efficient and safe mechanical operation, harm to human bodies in the open caisson excavation sinking process is reduced, the safety risk and the investment of safety measure cost are reduced, meanwhile, the construction period is shortened, and the engineering cost is saved; by adopting the construction method, the earthwork digging, transporting and backfilling volume can be greatly reduced, the construction speed is increased, and the construction cost is reduced.
本发明公开了一种富水砂层沉井施工方法，涉及建筑施工技术领域。施工方法包括：施工准备→基坑开挖→降水井施工→垫层施工→钢筋绑扎及模板支拆→脚手架施工→混凝土浇筑→井壁预留孔洞处理→沉井下沉→钢板桩施工→沉井封底→底板施工。本发明公开的富水砂层沉井施工方法通过将以往地下作业转变为地上作业，用工少，减轻劳动强度；施工方法中的沉井制作与下沉过程直接简单，测量监控更方便；施工方法以高效安全的机械作业代替普通的人工作业，减少沉井挖土下沉中对人身的伤害，降低了安全风险与安全措施费用的投入，同时缩短了施工工期，节约工程成本；采用本施工方法可大大减少挖、运、回填土方量，加快施工速度，降低施工费用。
