Shell Expansion Rock Anchor Bolts prestressed hollow
1. product description
This kind of anchor bolt is applicable to secondary complicated geological condition, permanent support and preparative support. Steel expansion type anchor bolt can form up the primary support quickly, resist deformation of surrounding rocks, maintain their stability, and then grouting achieves everlasting reinforcement.
2. standard
TB/T 3209-2008<hollow bolt technical condition>
3. component
Expansion hollow anchor bolt is composed of expansion steel anchor head, full thread hollow anchor body, stopper plug, arch plate, and nut.
4. specification
form up the primary support quickly, resist deformation of surrounding rocks, maintain their stability,the design of the hollow, realizes the function and the grouting.grout fully, and can realize grouting under pressurethe anchor body has good centralization, which avails to cover all of the anchor bolt ,avoiding corrosion, and achieving the purpose of long-term support.5. Application
General hollow grouting anchor bolt is applicable to engineerings of railway, highway, tunnel, mine, water control project, slope, dam, bridge group, banks of river,ocean,sea, foundations of high buildings and building reinforcement projects etc.
