YM13 12.7mm Prestressed Muti-holes Round Anchorage

General anchor construction and installation method
The general anchorage construction and installation method is to put a small number of explosives at the bottom of the blasthole, expand it into a spherical shape after several anchorage constructions and installations, and finally put explosives into the anchorages for construction and installation. Compared with the construction and installation method of blasthole anchors, this method has the advantages of good anchor construction and installation effects, high work efficiency, fast progress, and less explosive consumption. This method is often used to construct and install short pile anchors on shallow foundations.

Precautions
1. When the steel strands are braided, they should be straightened out individually and bundled into bundles without disorder. The extruded anchor or embossed anchor at the fixed end of the steel strand should be assembled with the bearing plate and the spiral reinforcement in advance;
2. The machinery, equipment, and instruments used for prestressing should be regularly maintained and calibrated;
3. Before the prestressed tendons are stretched, the concrete strength test report shall be provided. When the compressive strength of the concrete meets the design requirements and is not lower than 75% of the design strength grade, the prestress can be applied;

Application Field
Highway bridges, railway bridges, urban overpasses, urban light rail, high-rise buildings, water conservancy and hydropower dams, port terminals, rock mass slope protection anchorage, foundation reinforcement, tunnel mine roof anchorage, prestressed grids, subways, large buildings, Warehouse workshop, tower building, lifting of heavy objects, synovial film intermittent propulsion, bridge and tunnel jacking, large containers and ships, sleepers, replacement of bridge bearings, bridge and building reinforcement, steel bar engineering, antimagnetic and anti-corrosion engineering (fiber anchors ), carbon fiber reinforcement, pre-tensioned beam field construction, external prestressing engineering, cable-stayed cables, suspension cables, etc.
