Product Description
Rose shell-hollow Grouting anchor rods
The characteristics:
1\Easy installation, ensure that imposed by the pre-keep up to date with.
2\Active stretching, and profits can be 50LN, and implements appropriate hyper-tension.
3\Using conventional tools, single realization of tensioning operations
4\Can be controlled through the shank to achieve high pressure grouting, to improve the surrounding rocks.
5\Full control from production to installation to ensure quality.
Technology
1\Prestressed bolt installation and pre-imposed
(1)Hole drilling and cleared completely
(2)Rose shell will be installed anchor bolt is plugged directly into the hole of the bottom(Extra long bolt, connections available to connect)
(3)Preload the shank to ensure the anchor to the top and bottom of the hole immediately after l-bolts and tighten, then install the occluding, pads, nuts
(4)Connections General tension tool(Such as bolt tension meter), implementation of pre-stretch to the specified value.
2\Grouting
Grout seeks to put size package of prestressed bolt, effectively preventing Rod corrosion is bolt failure and Grout filled cracks, to improve the surrounding rocks. Therefore, Grouting must pay attention to quality, guaranteed Grouting full, use of special grout and Grout joints in order to guarantee the effectiveness of pre-anchorage system as a whole.
Taking into account the Grouting in prestressed bolt's main purpose is to prevent rust and filled cracks, to improve the surrounding rocks, it is suggested with good penetration of water slurry grout...
3\Grout stretching after the end of, the steps are as follows:
(1)Push the casting machine, connect the injection pipe and power
(2)Design is better than stirring slurry, and place it into the casting machine
(3)Start the casting machine, grout injection anchor holes, know that bolt trailer out of grout and Grout pressure is the design value
(4)Remove the grout joints, install plugging slurry to the next anchor grout, knowing that all anchor grout is complete
(5)Cleaning equipment
