Concrete pouring method in limited space
The invention relates to the technical field of arch bridge repair construction, in particular to a concrete pouring method in a limited space, which comprises the following steps: S1, construction preparation: S1.1, pouring equipment is conveyed to a position to be poured; s1.2, formwork supporting is carried out; s1.3, a pouring hole is formed in the formwork, and a pouring pipeline is installed; s1.4, a grout overflow hole is formed in the highest point of the pouring position; s2, pouring is conducted, specifically, S2.1, pouring equipment and a pouring pipeline are connected, and concrete is conveyed into the pouring pipeline through the pouring equipment; and S2.2, whether grout is discharged from the grout overflow hole or not is observed, when grout is discharged, whether grout is discharged from the full hole or not is observed, and when grout is discharged from the full hole, pouring is stopped, and the grout overflow hole is blocked. The gap between the arch-type corrugated steel plate and the arch web filled with concrete is more intuitive through the slurry overflow holes, cavities between the arch-type corrugated steel plate and the arch web are reduced, and reinforcement of the arch-type corrugated steel plate on the arch bridge is enhanced.
本申请涉及拱桥修复施工的技术领域，尤其是涉及一种有限空间内混凝土浇筑方法，其包括以下步骤：S1、施工准备，S1.1、将浇筑设备运送至待浇筑位置处；S1.2、进行模板支护；S1.3、在模板上开设浇筑孔并安装浇筑管道；S1.4、在浇筑位置的最高点开设溢浆孔；S2、浇筑，S2.1、连接浇筑设备和浇筑管道，用浇筑设备往浇筑管道内输送混凝土；S2.2、观察溢浆孔处是否出浆，出浆时，观察是否为满孔出浆，满孔出浆时，停止浇筑并封堵溢浆孔。本申请通过设置的溢浆孔使得混凝土充满拱式波纹钢板和拱腹之间的间隙变得更直观，减少了拱式波纹钢板和拱腹之间的空洞，增强了拱式波纹钢板对拱桥的加固。
