Auxiliary tool for pulling out anchor rod sleeve

Technical Field

The utility model relates to an auxiliary tool for pulling out a bolt sleeve.

Background

In the foundation pit supporting construction, when the anchor rod drilling machine drills into the side wall of a foundation pit for construction, the anchor rod drilling machine often meets the severe geological environment, or after cement paste is poured for the first time, the anchor rod casing pipe is often clamped in the soil due to the fact that the cement paste solidification time cannot be controlled. Even if the pipe drawing system configured by the pipe drawing system is used, the anchor rod sleeve pipe cannot be drawn out frequently, so that the anchor rod sleeve pipe is buried in soil and cannot be recycled, and the construction cost is increased.

When reason analysis is carried out, the anchor rod casing pipe is considered to be possibly clamped in a broken stone flowing sand layer, or after cement paste is solidified, the power of the self pipe drawing system is insufficient, and the pipe is not drawn. If the power of the jumbolter is increased, i.e. the motor of the system is increased, this will result in wasted equipment. And hydraulic pile driver is more general at present building site, and the power is great, and the function has similarly, if directly utilize hydraulic pile driver to pull out the stock sleeve pipe, then there is not the problem of stress point.
