Foundation pit support inner support construction technology
The invention discloses a foundation pit support inner support construction technology, and relates to the technical field of foundation construction, the technology comprises foundation pit drainage, three-shaft mixing pile construction, H-shaped steel construction, reinforced concrete support, lattice stand column pile construction, reinforcing mesh shotcrete anchor concrete surface layer construction and support replacement construction, and the foundation pit support adopts SMW construction method piles; wherein the three-shaft mixing piles have the effects of retaining soil and stopping water, and the three-shaft mixing piles form a continuous closed waterproof curtain on the outer side of a foundation pit by adopting a construction method of sleeving one hole. According to the foundation pit support inner support construction technology, the support rigidity is large, foundation pit deformation can be effectively controlled, the surrounding environment of a foundation pit can be protected, and the safety degree is high; lattice stand column piles and long spiral cast-in-place piles are adopted in the enclosure structure, an underground continuous wall, an H-shaped steel support and a concrete support can be adopted when the depth is large, and on the premise that safety is guaranteed, the construction period can be effectively shortened, and the construction efficiency can be effectively improved.
本发明公开了一种基坑围护内支撑施工工艺，涉及地基施工技术领域，该工艺包括基坑排水、三轴搅拌桩施工、H型钢施工、钢筋混凝土支撑、格构立柱桩施工、钢筋网喷锚砼面层施工和换撑施工，基坑围护采用SMW工法桩，其中的三轴搅拌桩兼具挡土、止水的作用，采用套接一孔的施工方法使得三轴搅拌桩在基坑外侧形成了一道连续的封闭式的止水帷幕。本发明基坑围护内支撑施工工艺支撑刚度较大，能有效控制基坑变形，有利于保护基坑周边环境，安全度较高；围护结构采用格构立柱桩采用长螺旋灌注桩，深度大时可采用地下连续墙，采用H型钢支撑和混凝土支撑，确保安全的前提下，能有效缩短工期，提高施工建设效率。
