Prestress reinforcement technology for roads and bridges
The invention relates to the technical field of bridge reinforcement, and discloses a road and bridge prestress reinforcement technology which comprises the following steps: S1, preparing a steel wire and a bridge: shearing the steel wire to a required length by using a wire cutter, polishing and removing rust for later use, and pre-burying a connecting anchor bolt on the bottom end surface of the bridge according to a preset position; according to the road and bridge prestress reinforcing technology, after the impact hand drill is used for punching and hole forming in the bottom end of a bridge according to the preset hole position, residual ash in a hole is removed through the hole cleaning air gun, cleanliness of the interior of the hole is guaranteed, then chemical liquid medicine is poured into the hole, the liquid medicine is mashed through the connecting anchor bolt, and rapid rotating stirring is conducted; the method comprises the following steps of: firstly, placing a connecting anchor bolt into a hole to ensure that the liquid medicine is uniformly smeared on the connecting anchor bolt, then, placing the connecting anchor bolt into the hole, adjusting the connecting anchor bolt to ensure the perpendicularity, and then, standing for 2 hours to anchor the connecting anchor bolt on a bridge, so that the connecting anchor bolt is more stable and does not loosen.
本发明涉及桥梁加固技术领域，且公开了路桥梁预应力加固技术，包括如下步骤：步骤S1：钢丝和桥梁准备：使用钢丝钳将钢丝剪切至需要的长度，并打磨除锈，备用，在桥梁底端面上根据预定位置预埋连接锚栓。该路桥梁预应力加固技术，通过使用冲击手钻按照预定的孔位位置在桥梁底端打孔，成孔后，利用清孔气枪将孔内余灰清除，保证孔内清洁，然后在孔内倒入化学药水，利用连接锚栓将药水捣碎并迅速转动搅拌，确保药水均匀涂抹于连接锚栓上，然后，将连接锚栓置于孔内，并调整连接锚栓以确保垂直度，随后静置2小时，使连接锚栓锚固在桥梁上，使得连接锚栓更加稳固，不会出现松脱现象。
