Prestressed anchor bolt grouting construction method
The invention discloses a pre-stressed anchor bolt grouting construction method which comprises the following steps: S100, measuring and positioning, and determining a chiseling area and a template mounting position; s200, scabbling is carried out, and laitance and a soft layer on the surface of the bearing platform concrete are removed; s300, a working face is cleaned; s400, wetting is conducted, and it is guaranteed that the concrete surface of the bearing platform is wet; s500, leveling is conducted, specifically, bedding slurry is laid on the concrete surface of the bearing platform for leveling, a plurality of leveling gaskets are arranged between adjacent anchor bolts of the anchor bolt cage, and the levelness of the leveling gaskets is leveled; s600, a fan bottom tower drum is installed; s700, formwork installation is conducted, specifically, the position of the formwork is adjusted according to the measuring and positioning marks, so that the distances between the formwork and the flange plate of the fan bottom tower drum are equal; s800, grouting is conducted; and S900, form removal is conducted. According to the construction method, the normative construction steps are provided, so that the problems that the grouting construction of the pre-stressed anchor bolt is not normative and the strength of hardened mortar is insufficient are effectively solved. The construction risk is effectively reduced and the construction quality is ensured.
本申请公开了一种预应力锚栓灌浆施工方法，包括如下步骤：S100、测量定位，确定凿毛区域和模板安装位置；S200、凿毛，将承台混凝土表面的浮浆及松软层剔除；S300、清理作业面；S400、润湿，保证承台混凝土表面湿润；S500、调平，在承台混凝土表面铺设坐浆料进行找平，在锚栓笼的相邻锚栓之间布设多个调平垫片，并对多个调平垫片的水平度进行调平；S600、风机底塔筒安装；S700、模板安装，根据测量定位的标记对模板的位置进行调整，使得模板与风机底塔筒的法兰盘之间的距离相等；S800、灌浆；S900、拆模。本申请通过提出规范的施工步骤，有效解决了预应力锚栓灌浆施工不规范，硬化砂浆强度不足的问题。有效降低施工风险，确保施工质量。
