Prestressed anchor characteristics
, Anchor and soil combine rock and soil structural stability, the Zhang La Shijia prestressed high strength reinforced, you can control the amount of deformation of the slope.
Construction drilling small aperture without large machinery, equipment simple and lightweight, and flexible.
3, the basic use of mechanized operations, the process is simple, construction safety.
Second, the scope
The prestressed anchor can be applied to construction projects, road traffic geotechnical slope reinforcement construction.
The process principle of prestressed anchor
Connection the prestressed anchor one end backgage structure, the other end is anchored in the rock and soil layers, and prestressed form pullout resistance, to withstand the geotechnical pressure, water pressure to the friction of the anchoring segment, anti-floating , against overturning the resultant structure tension, for the maintenance of the stability of the rock mass.
1, cut anchor should be used grinder cutting, shall not be used oxygen cutting or welding; the bolt then long flash butt or socket connection; freedom length should consider the length of the tension, tension side;
2, according to the size of the design drawings, was placed in the Anchorage positioning bracket bonding or banding fixed positioning bracket, must strapping lashing firmly;
Anchor finished appearance inspection specifications corresponding hole No. No. bolt length;
4 anchor finished as soon as possible to use, to avoid long-term storage; the prestressed anchor should be stored in a dry, clean place, bolt body bare Applied impregnated grease paper or plastic sheeting moistureproof processing, shall be subjected to mechanical damage.
5, anchor free section preservative treatment: coated anhydrous butter coat polyethylene plastic casing, the casing diameter greater than the outside diameter of the anchor bar 5mm to 10mm anchoring segment junction closed dense with a sealing plug to prevent grouting when the slurry into the free section.
