Device for preventing cast-in-situ bored pile reinforcement cage from floating upwards and using method thereof
The invention relates to the technical field of concrete construction, in particular to a device for preventing a cast-in-situ bored pile reinforcement cage from floating upwards. Comprising a clamping ring, a stable connecting rod, a positioning sleeve and a counterweight stone; wherein the clamping ring is connected with the counterweight stone through the stable connecting rod, and the positioning sleeve is arranged at the bottom of the clamping ring; a groove is formed in the top of the positioning sleeve, a pressing rod is arranged in the clamping ring, and the pressing rod is embedded in the groove in the top of the positioning sleeve. The device is larger in fixing area, better in fixing capacity and more beneficial to control over upward floating of the reinforcement cage; the guide pipe is effectively prevented from hooking the reinforcement cage, and the reinforcement cage is taken up when pulled up; for a short pile area, the reinforcement cage can be effectively prevented from floating upwards, and the pile forming quality is improved; the repeated utilization rate is high, and repeated use can be achieved in the using process, so that the cost is reduced.
本发明涉及混凝土施工技术领域，具体是一种用于防止钻孔灌注桩钢筋笼上浮的装置；包括卡环、稳定连杆、定位套管和配重石块；其中，卡环通过稳定连杆与配重石块连接，定位套管设置在卡环的底部；定位套管顶部设置凹槽，卡环中设置压杆，所述压杆嵌入在定位套管顶部的凹槽中。本装置固定面积更大，固定能力更好，更有利于控制钢筋笼上浮；有效防止导管挂住钢筋笼，上拔时将钢筋笼带上来；针对短桩区域地区，能有效防止钢筋笼上浮，增加成桩的质量；重复使用率高，且使用过程可重复使用，从而减少成本。
