What's the drilling depth of rebar planting construction?

In the rebar planting construction, the drilling depth is 15 times of the rebar diameter.

The construction method of planting steel bars is as follows:

According to the construction drawing, on the surface of the structure where the infilled wall is connected with the column or wall, the position of Rachel bar is set according to the design or structural requirements, and the line is elastic along the height direction.

When drilling, the impact drill should drill evenly perpendicular to the structural plane to control the verticality of drilling. The depth of the hole is controlled by the ejector pin on the impact drill. During the construction of reinforcement engineering, before the reinforcement binding, if the position of stirrups (wall horizontal bars) and the drilling position of Rachel bars may overlap, the spacing of stirrups (wall horizontal bars) should be adjusted appropriately according to the block modulus to avoid it as much as possible; When drilling, if you encounter stirrups or horizontal bars of concrete walls, you should properly adjust the drilling position according to the size of mortar joint, and the waste holes should still be treated as above.

After drilling a structural plane, hole cleaning operation can be carried out. The purpose of hole cleaning is to blow clean the dust in the hole, and cooperate with the electric blower.

Before mixing glue, check the preparation for planting reinforcement, ensure that drilling and hole cleaning have completed a construction period, organize acceptance, and make a record of acceptance of concealed works. At the same time, Rachel reinforcement has been prepared to meet the requirements of reinforcement planting operation.

Reinforcement planting should be carried out immediately after the glue injection is completed. In order to ensure that the colloid is full, after the glue injection is completed, the processed Rachel implant is slowly rotated and inserted into the rib implant hole, and adjusted to the specified position. During operation, it is necessary to rotate several times in a certain direction when inserting, so that the Rachel bar is tightly bonded with the surface of the concrete hole wall.
