Vertical pre-stressed anchor cable construction method
The invention relates to the field of buildings, in particular to a vertical pre-stressed anchor cable construction method, which comprises the following steps: firstly, limiting the setting range of an anchor cable through drilling, and in the step of anchor cable setting, driving a steel strand to vertically descend through a guide cap so as to subsequently form a vertically arranged anchor cable, so that the occupied horizontal space is reduced; primary grouting is conducted in the first blind hole through the first grouting pipe, so that the anchor cable is basically fixed and formed, then secondary grouting is conducted through the second grouting pipe after the first grouting pipe is pulled out, cement is evenly injected to the periphery from the grout outlet, and the cement evenly injected to the periphery flows to the bottom of the anchor cable under the action of gravity; and uniform strength of the anchor cable in all directions is ensured. After grouting is completed, all the anchor cables can be connected into one crown beam through the steps of manufacturing the crown beam, the acting force borne by all the anchor cables is transmitted under the action of the crown beam, and therefore the overall strength is improved. And finally, the vertical pre-stressed anchor cable used in the environment with the narrow space can be manufactured through tensioning, locking and forming.
本发明涉及建筑领域，尤其涉及一种垂直预应力锚索施工方法，先通过步骤制孔限定锚索的设置范围，在步骤锚索设置中，通过导向帽带动钢绞线竖直下放，以便后续形成竖直设置的锚索，从而减少占用的水平空间，通过第一注浆管向第一盲孔内一次注浆，使得锚索基本固定成型，再将第一注浆管拔出后通过第二注浆管二次注浆，通过从出浆口向四周均匀注射水泥，向四周均匀注射的水泥在重力作用下向锚索底部流动，确保了锚索各个方向的强度均匀。注浆完成后，通过步骤制作冠梁使得可以将各个锚索连接于一个冠梁中，使得各个锚索受到的作用力在冠梁的作用下传递，从而提高整体的强度。最后通过张拉锁定成型，即可制成用于空间狭小的环境的垂直预应力锚索。
