Anchor Rod Main Use And Composition Of The Anchor Must Have Factors
Anchor rod main use and composition of the anchor must have factors
Twist anchor rod is mainly used in mine roadway, railroad, slope and tunnel projects, the main reinforcement of the dam, its role is mainly to ensure the stability of the mine roadway and underground engineering surrounding rock. Mining anchor rods, also known as threaded steel anchor rods and mining left-hand threaded steel anchor rods, have the advantages of low cost, good supporting effect, easy operation, flexible use, and occupying less construction headroom.
Twist anchor is mainly used as support in underground mining, the anchor is deep into the ground, and the other end is connected with the building, the anchor can be divided into anchoring section and free section, the free section is mainly to apply prestressing force to the anchor; the anchoring section is mainly to increase the bonding friction between the anchoring solid and the soil layer, increase the pressure-bearing effect of the anchoring solid, and transmit the tension of the free section to the depth of the soil body. With high precision, small error, good quality and other characteristics, welded steel mesh is a welded mesh reinforcing products, is the longitudinal and transverse steel bars were arranged at a certain spacing and at right angles to each other, the intersection of the strong resistance pressure welded together with the steel mesh.
Factors that must be present to make up an anchor bar:
1. a bar with a tensile strength higher than that of the geotechnical body
2. one end of the rod can be in close contact with the geotechnical body to form friction (or bonding) resistance
3. the other end of the rod is located outside the geotechnical body to form a radial resistance to the geotechnical body.
Twist anchor manufacturer produces the anchor as a tensile member deep into the ground, it is connected with engineering structures at one end, and the other end is deep into the ground, the whole anchor is divided into the free section and anchorage section, the free section refers to the tension at the head of the anchor to the anchor solid area, and its function is to apply pre-stressing force to the anchor; the anchorage section refers to the area where the cement slurry binds the pre-stressing tendons with the soil layer, and its function is to increase the friction effect of the anchorage to increase the resistance to friction, and increase the resistance to friction. Its function is to increase the friction between the anchor solid and the soil layer, increase the pressure-bearing effect of the anchor solid, and transmit the tension of the free section to the depth of the soil.
