Construction method adopting deep foundation pit support anchor structure for supporting
The invention belongs to the technical field of infrastructure construction, and discloses a construction method adopting a deep foundation pit support anchor structure for supporting. The construction method comprises the following steps that water stop curtain construction is carried out through a stirring pile; supporting piles and stand column piles are constructed; earthworks at a construction site are excavated; crown beams and inner supports are constructed; anchor rods and hanging net ejector anchors are constructed; and inner support are replaced and detached. The method is novel in design, and it is effectively ensured that deep foundation pit displacement and surrounding building sedimentation are within specifications; vertical space of a foundation pit is not occupied, large equipment can be used for construction during earthwork excavation, soil does not need to be dumped or transferred, and earthwork excavation is facilitated; installation of the large equipment during later main body construction is facilitated; the supports only need to be replaced once during later main body construction, main body construction and backfilling of the foundation pit are facilitated; and the working procedure is simple, and the construction efficiency is improved.
本发明属于基建施工技术领域，公开了一种采用深基坑撑锚结构支护的施工方法，包括：通过搅拌桩进行止水帷幕施工；进行支护桩、立柱桩施工；施工点土方开挖；进行冠梁、内支撑施工；进行锚杆、挂网喷锚施工；内支撑换撑及拆除施工。本发明设计新颖，有效的保证深基坑位移和周边建(造)物沉降在规范以内；不占基坑竖向空间，土方开挖时可采用大型设备进行施工，不需要倒土或转运，便于土方开挖；对后期主体施工大型设备安装有利；后期主体施工时只需换撑一道，便于主体施工和基坑回填；工序简单，提高了施工效率。
