Fully-bonded prestressed steel anchor pipe cable structure and construction method thereof
The invention discloses a fully-bonded prestressed steel anchor pipe cable structure and a construction method thereof. The structure combines the advantages of a prestressed anchor cable and an accurate control grouting technology, the strength of a rock-soil body and the bonding force of the rock-soil body and a steel anchor pipe are improved through accurate control grouting of the steel anchor pipe, a steel strand is implanted into the steel anchor pipe, prestress is constructed at the bottom of the steel anchor pipe, the stress mode of the prestress steel anchor pipe is changed, and anchoring force is greatly improved; and the structure has the advantages of being reasonable in structure, advanced in technology, economical, reasonable, good in anti-corrosion effect and the like, and is a novel side slope reinforcing technology suitable for side slope anchoring.
本发明公开了一种全粘结型预应力钢锚管索结构及其施工方法，结合了预应力锚索与精准控制注浆技术的优点，通过钢锚管精准控制注浆提高岩土体强度及岩土体与钢锚管的粘结力，在钢锚管内植入钢绞线通过在钢锚管底部施工预应力，改变了预应力钢锚管受力模式，大大的提高了锚固力，具有结构合理、技术先进、经济合理、防腐效果好等优势，是一种适用于边坡锚固的新型边坡加固技术。
