Soft soil area pipe jacking reaction wall composite structure and green construction technology thereof
The invention provides a soft soil area pipe jacking reaction wall composite structure and a green construction technology thereof. The soft soil area pipe jacking reaction wall composite structure comprises a foundation bottom plate of a starting construction well, and a temporary reaction wall is perpendicular to the foundation bottom plate; the groove type steel rib walls are arranged on the two sides of the temporary reaction wall at equal intervals. The limiting steel frame is arranged on the rear side of the temporary reaction wall and staggered with the groove type steel rib wall. The jacks are arranged in the corresponding limiting holes in the limiting steel frame in a penetrating mode, one ends of the jacks abut against the temporary reaction wall, and the other ends of the jacks abut against the jacking iron; the recoverable pre-stressed anchor rods are symmetrically distributed below the foundation slab; the four sets of prestressed stay cables are symmetrically arranged on the two sides of the temporary reaction wall. According to the structure, pushing counter-force is transmitted to the foundation bottom plate and the foundation soil body, the foundation bottom plate is prevented from sliding and warping, other components are assembled and can be recycled, mounting and dismounting are convenient, resources can be saved, and the environment can be protected; and a green and low-carbon solution is provided for solving the problem of insufficient bearing capacity of a traditional reaction wall in soft soil area pipe jacking construction.
本发明提供一种软土区顶管反力墙复合结构及其绿色施工工艺，包括始发施工井的基础底板，临时反力墙垂直于基础底板；凹槽型钢肋墙等间距的设置在临时反力墙两侧；限位钢架设置在临时反力墙后侧，且与凹槽型钢肋墙交错设置；各千斤顶穿设在限位钢架上对应的限位孔中，千斤顶的一端与临时反力墙相抵接，另一端与顶铁相抵接；可回收预应力锚杆对称分布在所述基础底板下方；四组预应力斜拉索对称布置于临时反力墙两侧。本发明结构将顶推反力传递至基础底板和地基土体，防止基础底板产生滑移和翘曲，其余构件均为装配式可回收利用，安装拆卸方便，能够节约资源和保护环境，为软土区顶管施工中传统反力墙的承载能力不足问题提供绿色低碳的解决方案。
