End plugging device and plugging method for prestressed pipeline grouting
The invention discloses an end plugging device and plugging method for prestressed pipeline grouting. The method comprises the steps: installing a sealing cover covering an anchorage device on an anchorage device backing plate, and enabling the sealing cover to be in sealed connection with the anchorage device backing plate; pouring concrete into a corrugated pipe through grouting holes in the anchorage device base plate so as to carry out grouting work; and in the concrete initial setting stage, removing a sealing cover, cleaning the anchorage device, and removing concrete which is not completely solidified at the anchorage device. The beneficial effects of the end plugging device and plugging method are that: according to the scheme, the sealing cover and the anchorage device base plateare connected to form a closed space; after the sealing cover is mounted, the grouting work can be performed, so that extra waiting time is saved, and the construction period can be effectively shortened; the grouted slurry enters the sealing cover through the gap between the anchorage device and the anchorage device base plate, so that the pressure on the inner side and the outer side of the anchorage device is kept balanced, the pressure of the slurry can be continuously kept in the grouting process to ensure dense grouting, and thus the construction quality and the service life of a bridgeare ensured.
本发明公开了一种用于预应力管道压浆的端头封堵装置及封堵方法，在锚具垫板上安装罩住锚具的密封罩，使密封罩与锚具垫板密封连接；通过锚具垫板上的灌浆孔灌浆孔向波纹管内灌注混凝土以进行压浆工作；混凝土初凝阶段移除密封罩，并对锚具处进行清洗，去除锚具处没有完全凝固的混凝土。本发明的有益效果是：本方案利用密封罩与锚具垫板连接能够形成密闭的空间，密封罩安装好之后即可进行压浆的工作，省去额外的等待时间而能够有效缩短工期，灌注的浆液通过锚具与锚具垫板之间的间隙进入密封罩内部，使锚具内外两侧的压力保持平衡，能够在压浆的过程中持续保持浆液的压力而保证压浆密实，从而保证桥梁的施工质量以及使用寿命。
