Specification, installation embedded depth requirements of chemical anchor bolt:

1. According to the engineering design requirements, drill holes at corresponding positions in the base material (such as concrete). The hole diameter, hole depth bolt diameter shall be determined by professional technicians field test.

2. Drill with impact drill water drill before using chemical anchor bolt.

3. Use special air cylinder, brush compressed air machine to clean the dust in the drilling hole. It is recommended to repeat it no less than 3 times, there should be no dust open water in the hole.

4. Ensure that the bolt surface is clean, dry free of oil.

5. Confirm that there is no abnormal phenomenon such as appearance damage medicament solidification in the glass tube anchoring bag, put its round head outward into the anchor hole push it to the bottom of the hole.

6. Use electric drill special installation fixture to insert the screw into the hole bottom by strong rotation, the impact method shall be adopted.

7. when rotating to the bottom of the hole marking the position on the bolt, stop rotating immediately, remove the mounting fixture, prevent the disturbance before the gel is completely solidified. Overtime rotation results in the loss of glue affects the anchoring force. (the rotation time shall exceed 30 seconds, the rotating speed shall be less than 300 rpm more than 750 rpm, the bolt propulsion speed shall be about 2cm / s, the impact method is allowed.
