Construction method of hot-melt type recoverable pressure dispersing type expansion anchor cable
In a method, an umbrella-shaped mechanical drill bit is adopted for broaching of an expansion anchoring section, different drilling speeds can be set according to different soil properties, good stratum adaptability is achieved, and the hole forming diameter is stable. Hole flushing is carried out after broaching, sediments deposited at the bottom of the expansion anchoring section in the hole forming process are removed, an anchor cable expansion anchoring section diameter measuring instruction is used for detecting the diameter of the expansion anchoring section, the uniform hole diameter ofthe expansion anchoring section is further guaranteed, reliable bonding between an anchor cable grouting body and soil mass can be achieved, the hole wall soil mass is stable, the pulling resistanceof an anchor rod is large, high bearing force is achieved, and the construction quality of a hot-melt type recoverable pressure dispersing type expansion anchor cable, the safety of a foundation pit and the recoverability of the anchor cable are effectively guaranteed. The construction process is simple, and the actual operation performance is high.
本发明方法采用伞状机械钻头进行扩体锚固段的扩孔，能够根据不同的土质设置不同的钻进速度，具有良好的地层适应性，成孔直径稳定。在扩孔后进行了洗孔，去除扩体锚固段底部在成孔过程中存积的沉渣，并使用锚索扩体锚固段直径测量仪器对扩体锚固段的直径进行检测，进一步确保扩体锚固段的孔径均匀，能够实现锚索注浆体与土体之间的可靠粘结，孔壁土体稳定，锚杆抗拔力大，具有高承载力，有效的保证了热熔式可回收压力分散型扩体锚索的施工质量、基坑安全及锚索的可回收性。本发明施工工艺简单，实操性强。
