Construction method of pre-stressed anchor cable frame beam structure
The invention discloses a construction method of a pre-stressed anchor cable frame beam structure, and relates to the technical field of slope support. The construction method comprises the following steps that 1, a side slope is excavated; 2, after the side slope is excavated, anchor holes are formed in the side slope, the hole opening positions of the anchor holes are marked at a node A and a node B, and the node A and the node B are both located in the center of the intersection position of a cross beam and a vertical beam in a prefabricated frame beam; 3, anchor holes are drilled, anchor cable bodies are installed, and then anchor hole grouting is conducted; 4, after anchor hole grouting is completed, a frame beam foundation trench is excavated, and a frame beam is constructed; 5, after frame beam construction is completed, the anchor cables are tensioned and locked; and 6, after the anchor cables are tensioned and locked, grout supplementing and anchor sealing are conducted on the anchor head. By the adoption of the scheme, the pre-stressed anchor cables can be combined with the frame beams, the frame beams play a role of anchorage piers, and due to the fact that the effective contact area of the frame beams and the slope surface is large, deformation of the slope body under the action of the anchor cables can be limited.
本发明公开了一种预应力锚索框架梁结构的施工方法，涉及边坡支护技术领域，包括以下步骤：步骤一：开挖边坡；步骤二：开挖边坡后，将锚孔测放在边坡上，并在节点A和节点B处标明锚孔开孔位置，所述节点A和节点B均位于预制框架梁中的横梁和竖梁交叉处中心位置；步骤三：锚孔钻造，并安装锚索体，然后进行锚孔注浆；步骤四：锚孔注浆完成后，开挖框架梁基槽，并施工框架梁；步骤五：框架梁施工完成后，对锚索进行张拉锁定；步骤六：锚索张拉锁定完成后，对锚头进行补浆和封锚；采用本方案，能将预应力锚索与框架梁结合，框架梁起到锚墩的作用，由于框架梁与坡面的有效接触面积大，坡体在锚索作用下的变形能得到限制。
