Anchor bar specifications Anchor bar manufacturer Anchor bar 2016 new price 186 0379 3535
Product Overview:
Ordinary hollow grouting anchor bar is evolved from self-drilling anchor bar by removing drilling function. It consists of a full-threaded hollow anchor bar body, with anchor head, washer plate, nut, grouting plug, etc. Each component is designed to ensure full and compact grouting, so that the grout can penetrate into the rock fissures under pressures of up to tens of kilograms, and washer plate and nut can be easily installed.Anchor bar body: The entire surface is continuous wave-shaped thread, which facilitates cutting and extending of the anchor bar. Compared with smooth bar, it increases the bonding area between the bar and grouting material, thus improving the anchoring force. With hollow design, the hollow body serves directly as drilling high-pressure water channel and grouting channel. Compared with solid bar, better stiffness and shear strength can be obtained through grouting.
Grouting plug: Made of rubber material, combined with pressure grouting, it has certain sealing effect, facilitating the fullness and compactness of grouting.
Washer plate: Hot-rolled washer plate is used to adhere to the rock surface and bear greater stress from the rock.
Nut: Semi-spherical or hexagonal nut can concentrate the stress of the rock on the washer plate.
Anchor head: Plastic anchor head can not only fix and center the anchor bar body, but also generate certain anchoring force after grouting in the rock.
Product features:
1. Hollow design enables the anchor bar to fulfill the function of grouting pipe, avoiding the loss of grout caused by the traditional construction process when the grouting pipe is pulled out.
2. Full grouting and pressure grouting can be achieved to improve engineering quality.
3. Due to the functions of various accessories, the centrality of the bar body is good, and the grout can wrap the entire length of the anchor bar to avoid the risk of corrosion, achieving the purpose of long-term support.
4. Easy installation, without the need for on-site threading, washer plate and nut can be conveniently installed.
5. Combined with the supporting anchor bar special grouting pump and grouting process, it is currently a anchoring system in China that has solved many problems of traditional anchoring support.
Application range:
1. Radial reinforcement: Hollow anchor bars replace traditional grouting anchor bars for radial reinforcement, completely solving many defects in the traditional grouting anchor bar construction process, such as insufficient grouting and inability to achieve pressure grouting, ensuring engineering quality.
2. Slope reinforcement: Using hollow anchor bars to reinforce unstable slopes is not only simple and cost-effective, but also convenient and effective.
3. Foundation pit support: Using hollow anchor bars for foundation pit reinforcement is not only simple in process, but also can achieve pressure grouting to improve the surrounding rock conditions of the foundation pit.
Construction process:
Mainly used for systematic support of surrounding rocks with medium good geological conditions.
1. Drilling: Drill holes with a common rock drill and clean the holes.
2. Insert anchor bar: Insert the hollow grouting anchor bar with installed anchor head into the hole.
3. Install grouting plug, washer plate, nut: Install vent pipe according to the surrounding rock conditions.
4. Connect grouting machine: Connect the end of the anchor bar to the selected grouting machine through the grouting machine.
5. Grouting: Start the grouting machine, if pressure grouting is needed to improve the surrounding rock structure, just wait for the pointer on the pressure gauge to rise to the design pressure.
