Reinforced tension-compression composite anchor rod and construction method thereof
The invention discloses an enhanced tension-compression composite anchor rod and a construction method thereof, and relates to the technical field of rock-soil anchoring engineering.The anchor rod structurally comprises a first steel strand and a second steel strand, the first steel strand penetrates through a first bearing plate and abuts against a second bearing plate, and the second steel strand penetrates through the first bearing plate and the second bearing plate and then abuts against a guide cap at the bottom of a drill hole; the first steel strand is fixedly provided with a connecting sleeve at the bottom of the first bearing plate, the second steel strand is fixedly provided with a connecting sleeve at the bottom of the second bearing plate, the second steel strand is provided with a fixing sleeve at the top of the first bearing plate, the first grouting pipe extends to the bottom of the drill hole, and the second grouting pipe extends to the bottom of the second bearing plate. According to the construction method of the enhanced tension-compression composite anchor rod, the first pressure-bearing plate and the second pressure-bearing plate can be used for bearing cooperatively, the compression bearing capacity of the pressure-bearing anchoring section is guaranteed, and the situation that slurry is crushed before the uplift bearing capacity of the pressure-bearing anchor rod section reaches the limit is avoided; and the first grouting pipe can be repeatedly grouted, so that materials are saved, and the uplift bearing capacity can be remarkably improved.
本发明公开一种增强式拉压复合型锚杆及其施工方法，涉及岩土锚固工程技术领域，该锚杆结构包括穿过第一承压板抵顶在第二承压板上的第一钢绞线和穿过第一承压板与第二承压板后抵顶在钻孔底部导向帽上的第二钢绞线，第一钢绞线在第一承压板底部固定有连接套，第二钢绞线在第二承压板底部固定有连接套，第二钢绞线在第一承压板顶部设有固定套，第一注浆管伸至钻孔底部，第二注浆管伸至第二承压板底部。采用本发明增强式拉压复合型锚杆施工方法，可以利用第一承压板与第二承压板协同承载，保障承压锚固段的受压承载力，避免承压锚杆段的抗拔承载力达到极限前出现浆体被压碎；且第一注浆管可以重复注浆，不仅节省材料，而且可以显著提高抗拔承载力。
