Anchor rod structure, construction method of anchor rod and anchor rod body formed by construction method
The invention discloses an anchor rod structure which comprises a bus base material, a tensioning structure and a fixing structure, and the fixing structure is located at the lower end of the bus base material and used for anchoring of the lower portion of the anchor rod structure. The tensioning structure is positioned at the upper end of the bus base material and is used for tensioning and locking the bus base material; an isolation structure is arranged outside the bus substrate, and a first annular space structure is formed between the inner side of the isolation structure and the outer side of the bus substrate; the anchor rod structure further comprises a side grouting pipe, the side grouting pipe extends to the bottom from the top of the anchor rod structure, and the bottom of the side grouting pipe communicates with the bottom of the first annulus structure. An internal space defined by the first annular structure and the side grouting pipe is isolated from the exterior of the isolation structure and the exterior of the side grouting pipe, and a secondary grouting reverse discharging channel is formed. Therefore, the problem of later-stage water seepage of the anchor rod is thoroughly solved, and the potential safety hazard of a house structure, the later-stage water stopping difficulty and the engineering cost caused by failure of tensioning acting force due to corrosion of an anchoring part at the anchoring end caused by long-term water seepage are avoided.
本发明公开了一种锚杆结构，包括母线基材、张拉结构和固定结构，其中固定结构位于母线基材的下端，用于锚杆结构下部的锚固；张拉结构位于母线基材的上端，用于母线基材的张拉及锁固；母线基材的外部设置有隔离结构，隔离结构的内侧与母线基材的外侧之间形成第一环空结构；锚杆结构还包括旁侧注浆管，旁侧注浆管从锚杆结构的顶部延伸至底部，旁侧注浆管的底部与第一环空结构的底部连通；第一环空结构及旁侧注浆管所限定的内部空间，与隔离结构及旁侧注浆管的外部隔离，构成二次注浆反排通道。借此，彻底解决了锚杆后期渗水问题，避免了由长期渗水而造成锚固端锚固件的腐蚀而使张拉作用力失效造成房屋结构的安全隐患以及后期止水难度和工程成本。
