Deformation control reinforcing method for double-line different-diameter large pipe jacking drill penetrating building structure
The invention relates to the technical field of pipeline construction, in particular to a deformation control reinforcing method for a double-line different-diameter large pipe jacking drill penetrating building structure. The invention provides a deformation control reinforcement method for a double-line different-diameter large-scale pipe-jacking drill-through building structure, which comprises the following steps of: respectively wedging tubular steel sheet pile supports in appointed positions on two sides of an expressway foundation, and pre-sinking a working well to a designed elevation in the tubular steel sheet pile supports; then grouting is conducted between the outer wall of the working well and the inner wall of the tubular steel sheet pile support and in the outer side area of the tubular steel sheet pile support; and one fan-shaped steel sheet pile support is wedged into each designated position again, and the fan-shaped steel sheet pile supports and the tubular steel sheet pile supports are coaxially arranged. In the early stage of construction, the reinforcing method is adopted for consolidating the corresponding stratum, the stability of the excavation working face is guaranteed, the collapse phenomenon or the problem of ground subsidence deformation is avoided, and the personal safety of constructors in the jacking excavation process is effectively guaranteed.
本发明涉及管道施工技术领域，具体涉及双线异径大型顶管钻穿建构筑物的变形控制加固方法。本发明提供的双线异径大型顶管钻穿建构筑物的变形控制加固方法，所述方法包括：在高速公路地基两侧指定位置分别楔入管状钢板桩支护，在管状钢板桩支护内预沉工井至设计标高，之后在工井外壁和管状钢板桩支护内壁之间以及管状钢板桩支护的外侧区域注浆；在所述指定位置分别再次楔入一个扇形钢板桩支护，扇形钢板桩支护与管状钢板桩支护同轴设置。在施工前期采用本发明的加固方法对相应地层进行固结，保证开挖工作面的稳定性，避免出现塌方现象或造成地面沉降变形的问题，有效保证顶进开挖过程中施工人员的人身安全。
