Foundation pit side slope Larsen steel sheet pile reinforcing construction method
The invention relates to the technical field of foundation pit side slope reinforcement, and discloses a foundation pit side slope Larsen steel sheet pile reinforcement construction method which comprises the following steps: measuring and positioning: measuring and paying off the axis of a steel sheet pile by a measurer, inserting a positioning steel bar on the ground to mark a starting point, marking the axis by using a measuring rope, and inserting and driving the positioning steel sheet pile. According to the construction method for reinforcing the Larsen steel sheet pile on the side slope of the foundation pit, the pit bottom of the foundation pit is reinforced by adopting the three-pipe method jet grouting pile at the initial stage, so that the construction strength of the foundation pit can be improved, and the potential safety hazard caused by a silt layer in the construction process of the Larsen steel sheet pile is met; the stability of the Larsen steel sheet pile unearthed ramp can be effectively improved through the modes of driving the anchor rods, grouting and anchoring, installing the anchoring pedestal and pulling and anchoring for fixing, the time from steel sheet pile construction to slope surface concrete pouring is short, and meanwhile the structural strength and the construction progress of a foundation pit main body can be well guaranteed.
本发明涉及基坑侧边坡加固技术领域，且公开了一种基坑侧边坡拉森钢板桩加固施工方法，包括以下步骤：测量定位：测量员开展钢板桩轴线测量放线，在地面上插入定位钢筋标识起点并用测量绳进行轴线标记后，进行定位钢板桩的插打。该基坑侧边坡拉森钢板桩加固施工方法，通过初期对基坑坑底采用三管法旋喷桩对坑底进行加固，能够有提高即基坑施工强度，满足拉森钢板桩施工过程中遇到淤泥层所带来的安全隐患，而在拉森钢板桩插打过程中，通过打设锚杆、注浆锚固以及安装锚定台座并拉锚固定的形式，可有效提高对拉森钢板桩出土坡道的稳固性，从钢板桩施工至坡面混凝土浇筑，用时时间少的同时，还能极好地保证了基坑主体结构强度以及施工进度。
