Construction method for erecting and supporting foundation pit
The invention relates to deep foundation pit engineering, in particular to a construction method for erecting and supporting a foundation pit. The construction method comprises the following steps that precipitation outside the foundation pit is controlled; foundation pit construction sections are excavated and cross braces are erected to the bottom of the pit; main structures are subjected to jumping section construction and the cross braces are disassembled, specifically, bottom plates of the main body structures are poured; a side wall formwork supporting bracket is built to horizontally support a side wall formwork; the bottommost cross brace is removed; deformation detection is conducted on the poured side wall, and precipitation control outside the pit is detected; the side wall formwork supporting bracket is heightened continually, a transverse plate formwork is constructed, and the transverse plate formwork is supported by using the side wall formwork supporting bracket to pour and form a transverse plate; and the rest part of the main body structure is poured, and the rest cross braces are removed. According to the construction method for erecting and supporting the foundation pit, the problem that permanent defects are brought to the waterproof quality of the main body structure due to the fact that a reserved support is dismantled finally is effectively solved, and the side wall formwork supporting bracket is used for supporting.
本发明涉及一种深基坑工程，特别是一种架撑基坑的施工方法，包含以下步骤：基坑外降水控制；开挖基坑施工段并由架设横撑至坑底；对主体结构进行跳段施工，拆除横撑，具体包括：浇筑主体结构的底板；搭建侧墙模板支撑支架来水平支撑侧墙模板；拆除最底部横撑；对已浇筑好的侧墙进行变形检测，且对坑外降水控制进行检测；继续加高侧墙模板支撑支架，施工横板模板，并利用侧墙模板支撑支架支撑横板模板浇筑成型横板；浇筑主体结构剩余部分，并拆除剩余横撑。本申请的一种架撑基坑的施工方法，有效地解决了最后拆除留撑导致对主体结构的防水质量带来永久性缺陷的问题，而且利用侧墙模板支撑支架来进行支撑。
