Cast-in-situ bored pile reinforcement cage positioner and bridge construction cast-in-situ bored construction method
The invention relates to the technical field of engineering construction, in particular to a cast-in-situ bored pile reinforcement cage positioner and a bridge construction cast-in-situ bored construction method. The cast-in-situ bored pile reinforcement cage positioner comprises a positioning ring, a positioning barrel is arranged on the positioning ring, a positioning rod penetrating through the positioning barrel is arranged in the positioning barrel, the positioning rod moves in the radial direction of the positioning ring, and a clamping piece is arranged at the end of the positioning rod and used for clamping a reinforcement cage; an air bag is arranged on the outer circumferential surface of the positioning ring, and can abut against the inner wall of the protective cylinder after bulging; a telescopic bag communicated with the air bag is arranged in the positioning cylinder, and the telescopic bag can drive the positioning rod to move after bulging. The bridge construction cast-in-situ bored pile construction method comprises the steps of pile position lofting, pile casing burying, slurry preparation, drilling, formed hole detection and hole cleaning, reinforcement cage installation, cast-in-situ bored pile reinforcement cage positioner installation and concrete pouring. The cast-in-situ bored pile reinforcement cage positioner has the effect of improving the simplicity and convenience of positioning work.
本申请涉及工程施工技术领域，尤其是涉及钻孔灌注桩钢筋笼定位器及桥梁施工钻孔灌注施工方法。本申请涉及的钻孔灌注桩钢筋笼定位器包括定位环，定位环上设有定位筒，定位筒内设有贯穿定位筒的定位杆，定位杆沿定位环的径向运动，定位杆端部设有夹持件，夹持件用于夹持钢筋笼；定位环外圆周面上设有气囊，气囊鼓起后可抵接护筒内壁；定位筒内设有与气囊连通的伸缩囊，伸缩囊鼓起后可驱动定位杆运动。本申请涉及的桥梁施工钻孔灌注施工方法包括桩位放样、护筒埋设、泥浆制备、钻孔、成孔检测及清孔、钢筋笼安装、安装钻孔灌注桩钢筋笼定位器、混凝土灌注几个步骤。本申请涉及的钻孔灌注桩钢筋笼定位器具有提高定位工作简便性的效果。
