Connecting construction method for vertical prestressed tendon and anchoring steel bar of prefabricated solid pile
The invention relates to a connecting construction method for a vertical prestressed tendon and an anchoring steel bar of a prefabricated solid pile, and belongs to the technical field of prefabricated pile construction. The connecting construction method comprises the steps that a connecting sleeve is prepared firstly, then an inverted-truncated-cone-shaped jacket is installed on a prestressed tendon and clamped and fixed in an inverted-truncated-cone-shaped bayonet in the bottom of the connecting sleeve, a compression spring is installed in the connecting sleeve, then a pier head with a connecting thread is arranged at the end of the anchoring steel bar, and finally, the pier head is in threaded connection with the interior of a top sleeve opening of the connecting sleeve. The connecting construction method is high in practicability and easy to operate, the connecting quality of the pile head anchoring steel bars can be effectively guaranteed, the workload of field operators is relieved, cost is saved, and consumption of a large amount of manpower and material resources is avoided.
本发明为一种预制实心桩竖向预应力筋与锚固钢筋的连接施工方法，属于预制桩施工技术领域。本发明方法先准备连接套筒，然后在预应力筋上安装倒圆台状的夹套并将其卡固在连接套筒底部的倒圆台形卡口内，并在连接套筒内安装压缩弹簧，接着在锚固钢筋端部设置带连接螺纹的墩头，最后将墩头螺纹连接在连接套筒的顶部筒口内即可。本发明方法实用性强、操作简单、可有效保证桩头锚固钢筋连接质量，减轻了现场作业人员的工作量，节约了成本，避免了大量人力物力的消耗。
