Positioning device for prefabricated pier body foundation anchor recess hole and construction method
The invention relates to the technical field of bridge construction, in particular to a positioning device for a prefabricated pier body foundation anchor recess hole and a construction method. The tops of a plurality of annularly distributed steel drums are connected with the bottom of a positioning frame, the positioning frame is arranged on a foundation formwork, a positioning assembly is lowered into the foundation formwork, and the positioning of the anchor recess hole can be accurately and quickly realized without fixing the steel drums through a steel pipe bracket, so that the positionprecision of the anchor recess hole is improved; and besides, the outer surfaces of the steel drums and polystyrene boards are coated with a release agent, the polystyrene boards have a shrinkage function, so that when the steel drums are pulled out, buffer force can be generated, the polystyrene boards are shrunk by the buffer force, gap are formed between the polystyrene boards and the steel drums, and thus the steel drums can be easily pulled out of the anchor recess hole. Therefore, according to the embodiment, the position precision of the anchor recess hole can be improved, and the difficulty of pulling the steel drums out of the anchor recess hole can be effectively reduced.
本申请涉及一种用于预制墩身基础锚穴孔的定位装置及施工方法，涉及桥梁施工技术领域，通过将多个环形分布的钢桶的顶部与定位框架的底部相连，并将定位框架置于基础模板上，定位组件下放至基础模板内，即可准确快速的实现锚穴孔的定位，无需通过钢管支架对钢桶进行固定，提高了锚穴孔的位置精度；另外，由于钢桶和聚苯乙烯板的外表面上均裹覆有脱模剂，且聚苯乙烯板具有收缩功能，当钢桶被拔出时会产生缓冲力，该缓冲力会使得聚苯乙烯板收缩，以致聚苯乙烯板与钢桶之间出现缝隙，进而使得钢桶可以很轻易地从锚穴孔内拔出，因此，本申请实施例不仅可以提高锚穴孔的位置精度，还可以有效降低钢桶从锚穴孔内拔出的难度。
