Inclined strut prestress finish rolling deformed steel bar grouting device between cable-stayed bridge towers and construction method thereof
The invention relates to the technical field of cable-stayed bridge main tower construction, in particular to a cable-stayed bridge inter-tower inclined strut prestress finish rolling deformed steel bar grouting device and a construction method thereof.The grouting device comprises the grouting device body, the grouting device body is installed between main towers and inter-tower inclined struts, and the main towers comprise the first main tower and the second main tower; an inter-tower inclined strut is mounted between the first main tower and the second main tower, the inter-tower inclined strut is connected with the main towers through inter-tower inclined strut bottom plates and prestressed tendons, and the grouting device is characterized by comprising an upper anchor backing plate, a grouting pipe, a slurry inlet pipe, an exhaust pipe, a spiral rib, a lower anchor backing plate, a fixed anchorage device and a tensioning anchorage device; the mud jacking pipe is composed of an upper auxiliary pipe, a corrugated pipe, a lower auxiliary pipe and a connecting pipe, and the corrugated pipe is arranged between the upper auxiliary pipe and the lower auxiliary pipe in a sleeved mode. The connecting structure has the beneficial effects that by arranging the auxiliary pipe, the problem that the anchor bearing plate and the corrugated pipe cannot be effectively connected is effectively solved, and the prestressed pipeline is prevented from being blocked in the concrete pouring process.
本发明涉及斜拉桥主塔施工技术领域，具体为一种斜拉桥塔间斜撑预应力精轧螺纹钢压浆装置及其施工方法，包括压浆装置，所述压浆装置安装在主塔与塔间斜撑之间，所述主塔包括第一主塔和第二主塔，所述第一主塔与第二主塔之间安装有塔间斜撑，所述塔间斜撑与主塔之间通过塔间斜撑底板和预应力筋连接，其特征在于：所述压浆装置包括上锚垫板、压浆管、进浆管、排气管、螺旋筋、下锚垫板、固定锚具和张拉锚具；所述压浆管由上辅助管、波纹管、下辅助管和连接管构成，所述上辅助管与下辅助管之间套设有波纹管；其有益效果在于：本发明中通过设置辅助管，有效解决了锚垫板与波纹管无法有效连接的问题，避免了混凝土浇筑过程中出现预应力管道堵塞。
