PSB finish-rolled twisted steel prestressed high-strength anchor rod for bedding slope treatment
The invention belongs to the technical field of anchor rods, discloses a PSB finish rolling twisted steel bar prestress high-strength anchor rod for bedding slope treatment, and aims to solve the problems that when an anchor cable and a common anchor rod are used for slope treatment, the strength is low, and installed strain gauges are prone to being damaged and cannot be detected for a long time. A plurality of strain gauges are arranged on the PSB finish rolling twisted steel, a bearing body structure is arranged on the peripheries of the strain gauges, the bearing body structure comprises a protection barrel, an annular groove is formed in the inner wall of the protection barrel, and threads are machined on the inner walls of the upper end and the lower end of the annular groove. An annular groove is formed in the outer wall of the protective cylinder, an insertion opening communicated with the annular groove is formed in the outer wall of the protective cylinder, a bearing plate is arranged at the upper end of the insertion opening, wire branch pipes are inserted into the insertion opening, each wire branch pipe is connected with at least one wire pipe, and external wires in the wire pipes are connected with strain gauges and strain gauges. According to the invention, the strain gauge can be well protected, so that the pre-stressed anchor rod can be detected for a long time.
本发明属于锚杆技术领域，公开了一种用于顺层边坡治理的PSB精轧螺纹钢筋预应力高强锚杆，为了解决锚索、普通锚杆在治理边坡时存在着强度低以及安装的应变片容易损坏无法进行长期检测的问题。本发明的PSB精轧螺纹钢筋上布置有多个应变片，应变片的外围设置有承载体结构，所述承载体结构包括保护筒，保护筒的内壁设置有环形凹槽，所述环形凹槽上端和下端的内壁上加工形成有螺纹，所述保护筒的外壁上开设有与环形凹槽相互连通的插接口，所述插接口上端设置有承载板，所述插接口内插入有导线支管，各个导线支管连接有至少一个导线管，所述导线管内的外接导线连接应变片和应变仪。本发明能够很好的保护应变片，以便于长期对预应力锚杆进行检测。
