Construction method of prefabricated concrete thin-wall segment cast-in-place framework protection slope
The invention provides a construction method of a prefabricated concrete thin-wall segment cast-in-place framework protection slope, and belongs to the field of roadbed accessory engineering construction. The construction method is mainly invented for solving the problem that an existing formwork erecting cast-in-place construction method is large in difficulty. After a formwork is assembled, concrete is poured into the formwork, and maintenance is carried out. A concrete pouring opening is formed in the surface of a fourth thin-wall segment, meanwhile, a concrete cover plate is prefabricated, n-shaped steel bars are pre-buried in the bottom of the concrete cover plate, framework grooving is carried out, a cup opening is formed in the position, corresponding to a wall framework, of a slope foot, a first thin-wall segment is inserted into the cup opening, and the other three segments are spliced and assembled through rabbets. After installation is finished, concrete pouring is carried out through the concrete pouring opening reserved in the fourth thin-wall segment, when concrete is about to be poured to the concrete pouring opening, a next set of first thin-wall segments are inserted, then the concrete cover plate is used for covering the concrete pouring opening, and the cover plate is connected with the concrete through the n-shaped steel bars. The construction method has the advantage of being low in construction difficulty.
一种预制混凝土薄壁节段现浇骨架护坡的施工方法属于路基附属工程施工领域。主要是为解决目前立模现浇施工方法难度大的问题而发明的。模板组装完毕后向模板内浇筑混凝土，养护。在第四节薄壁节段表面设混凝土浇筑口，同时预制混凝土盖板，混凝土盖板底部预埋几字型钢筋，进行骨架挖槽，在边坡脚对应墙骨架位置设杯口，将第一节薄壁节段插入杯口，其他三节分别通过企口拼插组装。安装完毕后，通过第四节薄壁节段预留的混凝土浇筑口进行混凝土浇筑，当混凝土快浇筑到混凝土浇筑口处时，插入下一组的第一节段薄壁节段，然后用混凝土盖板盖住混凝土浇筑口，盖板通过几字型钢筋与混凝土连接。优点是施工难度低。
