Method for erecting cast-in-place box girder full framing in reservoir and on dam body
The invention relates to a method for erecting a cast-in-place box girder full framing in a reservoir and on a dam body. The method comprises the steps of emptying the reservoir water level to the lowest; breaking the original overflow dam slope body width; blocking the blow-down pipe; removing the dam body slope surface; actually measuring the foundation bearing capacity of the surface soil body of the dam body through dynamic sounding; determining the thickness of dam body hardened concrete; excavating an underground water drainage channel; treating a horizontal ground foundation at a dam foot and hardening surface concrete; pouring a gravity type retaining wall at the dam foot; backfilling the retaining wall; digging step edge hardening concrete on the dam body edge; breaking a wave wall at the top of the dam body; breaking the side wall side of the dam body; erecting the bridge full-span full-joint-pouring full framing related to the reservoir according to the position, the transverse distance and the longitudinal distance of the scheme; breaking and removing a strip-shaped foundation on an original bottom plate; newly building a blow-down pipe in the drainage tank, and recovering related water conservancy facilities of the reservoir. According to the method, the design function of an original dam body is not damaged, damage to the original dam body is reduced, the requirement for the bearing capacity of the full framing can be met, permanent and temporary combination can be achieved, the dismantling cost is reduced, and the dam body is reinforced.
本发明是一种水库内及坝体上的现浇箱梁满堂支架搭设方法；包括放空水库水位至最低；破除原溢流坝斜坡体宽度；封堵放空管；清除坝体坡面；动力触探实测坝体表层土体的地基承载力；确定坝体硬化混凝土的厚度；开挖地下水排泄通道；坝脚处水平地面地基处理及表层混凝土硬化；坝脚处重力式挡墙浇筑；挡墙回填；坝体边挖台阶边硬化混凝土；坝体顶防浪墙破除；坝体边墙侧破除；涉及水库的桥梁全跨全联浇满堂支架按方案的位置、横距及纵距进行搭设；破除原底板上的条形基础；在泄水槽内新建放空管，恢复水库相关水利设施。本方法既不破坏原坝体设计功能，减少对原坝体的破坏，又能达到满堂支架承载力的要求，还能永临结合，减少拆除费用和加固坝体。
