Abstract
The utility model discloses a cleaning device for drill holes. The cleaning device consists of a shell of which the length is 2 to 4 meters and steel wire clusters, wherein the upper end of the shell is connected with a drilling rig by threads; the lower end of the shell is closed, and the outer diameter of the shell is 30 to 50 millimeters less than the diameters of the drill holes; a plurality of through holes and half holes are dilled on the shell from the bottom at intervals of between 15 and 20 centimeters; the steel wire clusters of which the lengths are between 40 and 50 millimeters are welded in the half holes; and the lengths of the steel wire clusters which are exposed from the shell are more than or equal to 30 millimeters. The cleaning device is reasonable in design, and the steel wire clusters are high in flexibility and hardness; the heads of the steel wire clusters are dispersed, and adhesive substances on hole walls and fillers in gaps can be swept effectively by increasing a contact area; and clear water rushes out of lower holes of the steel wire clusters and carries the swept debris out of a well, so the cleaning device can be suitable for drilled wells with any depths and is wide in application range.
Description
Technical field
The utility model relates to the boring cleaning device that a kind of pumping test is used.
Background technology
In the construction of the hydrology hole of present domestic solid mineral exploration, the interior pumping test of need holing obtains the boring hydrological data.Only be to use carbon dioxide well-flushing method at present, operate comparatively loaded down with trivial detailsly, do not reach expected effect.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of the utility model is for pumping test clean-out opening wall device in a kind of boring to be provided.
For achieving the above object, the technical scheme that the utility model is taked is: it is that housing and the steel wire of 2-4 rice bunch formed by length, and thread connection is adopted with drilling tool in the housing upper end, the housing lower end closed, and the housing external diameter is less than bore diameter 30-50 millimeter; Whenever from the bottom on housing, bore a plurality of open-works and half hole at a distance from 15-20 centimetre, be welded with length in half hole and be the steel wire bunch of 40-50 millimeter, steel wire bunch is exposed at outside length and is not less than 30 millimeters.
During use, this device is lowered in the boring with drilling tool, calculates the good drilling depth of cleaning of needing, start slush pump, pour clear water, the rotation drilling tool also slowly promotes, and this process can achieve the goal for several times repeatedly in position that needs clean.
The utility model is reasonable in design, and steel wire bunch pliability and hardness are higher, and steel wire bunch head disperses; Increase contact area and can effectively clear away the filler of bur and slit on the hole wall; Clear water is gone out from a steel wire bunch following hole, carries the foreign material under the cleaning, takes out of outside the well; Applicable to any degree of depth drilling well, applicable surface is wider.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-drilling tool, 2-thread connection, 3-housing, 4-open-work, 5-steel wire bunch
The specific embodiment
Accompanying drawing is an embodiment of the utility model, specifies present embodiment in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is that housing 3 and the steel wire bunches 5 of 2-4 rice formed by length, housing 3 upper ends and drilling tool 1 employing thread connection 2, and housing 3 lower end closed, housing 3 external diameters are less than bore diameter 30-50 millimeter; Whenever from the bottom on housing 3, bore a plurality of open-works 4 and half hole at a distance from 15-20 centimetre, be welded with length in half hole and be the steel wire bunches 5 of 40-50 millimeter, steel wire bunches 5 is exposed at housing 3 outer length and is not less than 30 millimeters.
When using present embodiment, be connected drilling tool 2 in housing 3 and the hole, put into boring to this device, start slush pump and pump into clear water, utilize the frictional force of steel wire bunches 5 and foreign material that water flow impact pressure will adhere to slit in hole wall and the hole to take out of under brushing.
