Description
Affiliated technical field
The utility model relates to a kind of drilling and sealing device, especially for the hole sealing device that upwards extends boring.
Background technology
Injection hole sealing is that reperfusion serosity in boring, carrys out filling borehole for the most frequently used processing method of discarded boring, prevents that boring from potential safety hazard occurring.Slip casting method is fairly simple for the downward borehole sealing of bearing of trend, because the density of slurries is generally greater than water, even finally also can be full of whole boring from aperture grouting slurries, plays good sealing of hole effect.And it is more difficult for bearing of trend borehole sealing upwards, the one, can not directly be in the milk from aperture, because slurries will flow out naturally like this, the 2nd, if orifice tube is installed to powerful mud jacking in hole in aperture, because boring is in relative closure state, the grouting pressure that slip casting needs is generally higher, and general slip casting machinery cannot meet at all.
Summary of the invention
In order to overcome the conventional deficiency of upwards extending drilling and sealing method sealing of hole difficulty, the utility model provides a kind of hole sealing device that upwards extends boring, and this device can be realized the effective sealing of hole to upwards extending boring.
The technical scheme that the utility model adopts is: the hole sealing device that upwards extends boring comprises that orifice tube, flange, flange cover plate, pretension screw, pvc pipe, pvc pipe valve, Grouting Pipe, grouting pump, slip casting valve.Flange and orifice tube specification are coincide, and both adopt welding manner to connect; Flange and flange cover plate gauge lattice and coincide, and both adopt pretension screw to connect; The pvc pipe that adopts small-bore, its total length is equal to or slightly less than drilling depth, and pvc pipe can be connected on the flange masking-out back side, and its front of covering link position on plate at flange connects pvc pipe valve, can in pvc pipe, inject fluid by pvc pipe valve; Slip casting valve is connected in flange masking-out; Grouting pump, Grouting Pipe, slip casting valve connect successively, and grouting pump can inject slurries in boring.
While upwards extending the hole sealing device use of holing, concrete step is: 1. the orifice tube with flange, orifice tube installation length 3～5m are installed in upwardly extending boring; 2. in hole, be lowered to pvc pipe, be lowered to length and be equal to or slightly less than drilling depth; 3. pvc pipe and flange being covered to plate is connected; 4. flange and flange illiteracy plate are closely connected by pretension screw; 5. grouting pump, Grouting Pipe, slip casting valve connect successively, open pvc pipe valve, by grouting pump, boring are carried out to slip casting, and in process, pvc pipe valve is always in open mode; 6. in the time that pvc pipe valve starts to return slurry, illustrate that boring is full of by slurries, stop grouting pump, close pvc pipe valve and slip casting valve, after slurries fully solidify, complete the shutoff to boring.
What the utility model was most crucial is in boring, to be provided with a pvc pipe, and in the time of slurries injection hole, gas can, from the row of pvc pipe China and foreign countries, reduce the difficulty of slip casting; And pvc pipe can also play the effect that checks slip casting effect, because pvc pipe is installed to the bottom of boring, only has in the time that slurries liquid level is elevated to foot of hole, and pvc pipe just can return slurry, in like manner pvc pipe returns slurry and illustrates that slurries have been full of boring.
The beneficial effects of the utility model are, this device can be applied to the sealing of hole operation of upwards extending boring, and its principle is simple, and easy to operate, effect is guaranteed.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the schematic diagram in the utility model use procedure.
In figure: 1. boring, 2. orifice tube, 3. flange, 4. flange covers plate, 5. pretension screw, 6.PVC pipe, 7.PVC pipe valve, 8. slip casting valve, 9. Grouting Pipe, 10. grouting pump, 11. slurries, 12. air.
Detailed description of the invention
In the drawings, orifice tube (2) coincide with flange (3) specification, and both adopt welding manner to connect; Flange (3) covers plate (4) specification with flange and coincide, and both adopt pretension screw (5) to connect; Select the pvc pipe (6) of small-bore, its total length is equal to or slightly less than boring (1) degree of depth; Pvc pipe (6) is connected on flange masking-out (4) back side, and its front of covering the upper link position of plate (4) at flange connects pvc pipe valve (7); Slip casting valve (8) is connected in flange masking-out (4); Grouting Pipe (9) one end connects slip casting valve (8), and the other end connects grouting pump (10); Grouting pump (10) can pumped slurry (11).When the utility model is implemented, concrete step is: the orifice tube (2) with flange (3), orifice tube (2) installation length 3～5m are first installed in boring (1); In hole, be lowered to pvc pipe (6) again, be lowered to length and be equal to or slightly less than boring (1) degree of depth; Then pvc pipe (6) and flange illiteracy plate (4) are connected, flange (3) and flange illiteracy plate (4) are closely connected by pretension screw (5); Finally open pvc pipe valve (7), slip casting valve (8) connects Grouting Pipe (9), Grouting Pipe (9) connects grouting pump (10), boring (1) is carried out to slip casting, slip casting pvc pipe valve in early stage (7) is by demobilization gas, in the time that pvc pipe valve (7) starts to return slurry, stop grouting pump (10), close pvc pipe valve (7) and slip casting valve (8), after slurries (11) fully solidify, complete the shutoff to boring (1).
