Device for cleaning a borehole

The invention relates to a device for cleaning a borehole, in particular in masonry.

To fasten anchors or screws in the masonry, a borehole is first drilled, which is then at least partially filled with a hardening adhesive or mortar into which the anchor or screw is inserted. After the adhesive or mortar has hardened, the anchor or screw is glued in the borehole. A firm anchoring presupposes that the adhesive or mortar also bonds with the borehole wall. However, this is prevented by the drilling dust adhering to the borehole wall. In most cases, this drilling dust cannot be blown out with compressed air. The invention aims to provide a remedy here.

The object of the invention is to create a borehole from Bohvstaub to clean.

This object is achieved with a device dsr

genus described at the beginning, which is marked

is by a brush at one end of an air blow tube,

that the outside diameter is smaller than the outside diameter

knife of the brush and at the other end a compressed air generator connected*

With the brush which can be introduced into the borehole and which can in particular have radially protruding bristles, the dust adhering to the borehole wall is loosened by the air flow emerging from the air blower pipe detected and thus transported out of the borehole. When the brush moves back and forth in the borehole a few times is, the borehole wall is practically free of drilling dust, so that the subsequently introduced Glue or mortar also adheres to the borehole wall.

A practical version is characterized in that the brush is connected to a rod or a rope which extends through the air blow tube and at its other end one on the end face of the end of the air blow tube attached to the compressed air feeder having supported abutment. Included the rod or rope can also be longer than the air blow tube.

In the following an exemplary embodiment of the invention shown in the drawing is explained; show it:

The device shown consists in its Grundsa'tz- | borrowed structure from a compressed air generator in the form a deformifer'baren balloon 1, from an attached Air blow tube 2 and a brush 3 with bristles protruding radially therefrom. The outside diameter the brush 3 is adapted to the inside diameter of the borehole 4 to be cleaned in a masonry 5. Of the The outer diameter of the air blowing tube 2 is smaller than the outer diameter of the brush 3. I.

In the embodiment shown, the brush is 3 connected to a rod or wire rope 6 which extends through the air blow tube 2 and at its other end an abutment 7 carries which on the face of the end attached to the balloon 1 8 of the air blow tube 2 is supported. The wire rope 6 is slightly longer than the air blow tube so that the Brush 3 is guided with play.

As shown in Fig. 2, the brush 3 with the air blowing tube 2 is introduced into the borehole 4 and repeatedly moved back and forth. In doing so, the dust adhering to the borehole wall is loosened. At the same time is by pressure an air flow generated on the balloon 1, which exits in the area of the brush 3 from the air-blowing tube 2, the Detected dissolved dust and transported it out of the borehole 4.
