Pile-plate-cable reinforcement strong-span foundation pit deep-buried pipeline suspension protection construction method
The invention relates to a pile-plate-cable reinforcement strong-span foundation pit deep-buried pipeline suspension protection construction method. The method comprises the steps of foundation pit supporting and retaining structure construction, pipeline two-side drilling cast-in-place pile construction, middle static drilling root planting pile construction, side static drilling root planting pile construction, crown beam and end plate construction, bailey beam erection, pipe joint hoop installation and suspension construction. The method has the beneficial effects that the contact strength between the pipe joints is effectively improved through the longitudinal anchor cables, so that the problem of leakage at the pipe joints in the suspension process is avoided, and the technical advantages are remarkable; a suspension system composed of the double Bailey truss beams, the pipe joint hoops and the pulley hoists can enable the pipelines to be evenly stressed and synchronously suspended and lifted, and the phenomenon that due to the fact that the pipelines are not evenly suspended, deflection is too large, and the pipelines are damaged is avoided; the static root drilling planting piles and the transverse bearing beams can be recycled and reused in the later period along with the development of suspension construction.
本发明涉及一种桩‑板‑索补强大跨基坑深埋管道悬吊保护施工方法，包括步骤：基坑支挡结构施工、管道两侧钻孔灌注桩施工、中部静钻根植桩施工、侧部静钻根植桩施工、冠梁、端板施工、贝雷梁架设、管接套箍安装和悬吊施工。本发明的有益效果是：通过纵向锚索有效提高管节之间的接触强度，从而避免了悬吊过程中的管接处的渗漏问题，技术优势显著；双榀贝雷桁架梁、管接套箍及滑轮起吊组成的悬吊系统能够使得管道均匀受力并同步悬吊提升，避免了因管道悬吊不均引起的挠度过大，造成管道破坏的现象；静钻根植桩和横向垫梁随着悬吊施工的开展，可以在后期进行回收再利用。
