Railway sound barrier foundation anchor bolt reinforcing method
The invention discloses a railway sound barrier foundation anchor bolt reinforcing method which comprises the following steps: S1, evaluating the actual service condition of original foundation anchor bolts, determining the number of the foundation anchor bolts capable of being used for bearing and the bearing capacity, and determining the number of newly added foundation anchor bolts; s2, a reinforcing steel plate is additionally arranged on an original steel stand column bottom plate, and meanwhile the position of a newly-added foundation anchor bolt and the size of the reinforcing steel plate are determined; s3, holes are formed in the corresponding positions of the reinforcing steel plates, meanwhile, H-shaped grooves matched with the sound barrier H-shaped steel stand columns are machined in the middles of the reinforcing steel plates, holes are formed in the corresponding positions of the concrete foundation, then the newly-added reinforcing steel plates are welded and fixed to the original steel stand column bottom plates and the roots of the sound barrier H-shaped steel stand columns correspondingly, and a new stress whole is formed; and S4, the newly-added anchor bolts penetrate through the reinforcing steel plates to be inserted into the concrete foundation holes, nuts are tightened, and reinforcing of the anchor bolts is completed. The method can be used for reinforcement after the railway sound barrier anchor bolt fails, and meanwhile, a concrete foundation does not need to be damaged in a large area.
本发明公开了一种铁路声屏障地脚锚栓加固方法，步骤如下：S1、对原有地脚锚栓实际服役情况进行评估，确定可用于承载的数量和承载能力，确定新增地脚锚栓个数；S2、在原有钢立柱底板上增设加固钢板，同时确定新增地脚锚栓位置和加固钢板大小；S3、在加固钢板相应位置处开孔，同时在加固钢板中间加工出与声屏障H型钢立柱匹配的H型槽，及在混凝土基础上相应位置处开孔，然后将新增加固钢板与原有钢立柱底板和声屏障H型钢立柱根部分别焊接固定，形成新的受力整体；S4、将新增地脚锚栓穿过加固钢板插入混凝土基础孔中，拧紧螺母，完成地脚锚栓的加固。本发明可用于铁路声屏障地脚锚栓失效后的加固，同时又不需进行大面积破坏混凝土基础。
