Construction process for jet grouting anchor rod
2008
The invention relates to a construction process for jet grouting anchor rod, which comprises the following detailed steps of: 1. setting out according to design requirements; 2. positioning a drilling machine; 3. drilling; 4. guniting; 5. lifting by jet grouting; 6. drilling for a second time; 7. guniting for a second time; 8. lifting by jet grouting for a second time; 9. installing and embeddinga rod body; and 10. pouring and capping. The construction process can overcome the technical problem that the anchoring effect of slip-casting type or mechanical type anchoring is poor, and breaks through the tradition, and the test demonstrates that the anchoring effect is better than that of slip-casting anchoring.
