Abstract
An aperture guard device comprises a grout tube, an operating platform, a turntable, a slip, a connecting sleeve, a floral tube, an aperture guard casing tube and a spray nozzle, wherein the turntable is fixed on the operating platform, and the turntable is connected with the slip on the same axis; the floral tube is provided with a plurality of rows of grout discharge holes; the aperture guard casing tube is installed below the floral tube and in threaded connection; the grout tube is installed in the floral tube and a protective casing tube; the grout tube is connected with the floral tube through the connecting sleeve, which are on the same axis; and the spray nozzle is in threaded connection with the lower end of the grout tube. The spray nozzle, the grout tube, the floral tube and the aperture guard casing tube are rotated with the turntable driving the slip, and lifted up or down at a speed set by the grout tube. The aperture guard device has the advantages of available application in the stratum where pores can not be formed and are easy to collapse, and avoidance of worry over the traditional PVC tube method and engineering cost increase due to consumption of disposable materials by using the steel aperture guard casing tube for protecting the wall of an aperture to jet grout directionally under high pressure.
Description
Technical field
The utility model relates to the high pressure jet grouting process equipment that is used for underground seepage control project, particularly relates to a kind of guard aperture device.
Background technology
High pressure jet grouting is respectively boring and grouting two procedures usually, utilize engineering driller to finish to satisfy projected depth, naked hole (hole wall is not with casing protection) that hole wall is smooth after, be lowered to grout pipe again to predetermined elevation, carry out jet grouting.If run into quicksand or the stratum in the hole of easily collapsing; pvc pipe commonly used carries out sleeve pipe follow-up boring; pvc pipe puts grout pipe in place to the protection of boring smoothly, and pvc pipe and stratum are native simultaneously by high speed water (slurry) jet cutting and crushing during high pressure jet grouting, thereby has guaranteed carrying out smoothly of grouting.Use the PVC tiretube process to have relevant technical specification, but, make people be the worry of this method to the unstability of present material market quality, pvc pipe can not be achieved one's goal and be shredded by high-speed jet, and to the influence of height spray wall quality, in addition, the fragment of pvc pipe is to the influence of height spray wall barrier properties.
The utility model content
The technical problems to be solved in the utility model; provide a kind of can not pore-forming, easily collapse in the stratum in hole; utilize steel sleeve protection hole wall can carry out high pressure jet grouting, exempt pvc pipe guard aperture in the past and the material brought is stable inadequately and the pvc pipe fragment to the antiseepage influence of height spray impervious wall with exempt the guard aperture device that disposable PVC material consumption reduces construction cost.
The technical scheme that adopts is:
A kind of guard aperture device comprises grout pipe, job platform, rotating disk, slips, adapter sleeve, floral tube, guard aperture sleeve pipe and shower nozzle.Described rotating disk is fixed on the job platform, and rotating disk is connected on same axis with slips, is laid with many row's plasma discharges hole on the described floral tube wall, and the guard aperture sleeve pipe is installed in below the floral tube, and by being threaded.Grout pipe is packed in floral tube and the guard aperture sleeve pipe, and grout pipe is connected with floral tube by adapter sleeve, and on same axis, shower nozzle is threaded with the grout pipe lower end.Described shower nozzle, grout pipe and floral tube and guard aperture sleeve pipe drive slips by rotating disk and rotate, and the speed of setting with grout pipe rises or descends again.
Above-mentioned grout pipe can be triple grout pipes or double grout pipe.
Above-mentioned guard aperture sleeve pipe and floral tube outer wall are equipped with the long key of guide-localization.
The utility model has the advantages that: can not pore-forming guiding, easily collapse and use in the stratum in hole, utilize steel guard aperture casing protection hole wall to carry out high pressure jet grouting, worry and the disposable material consumption exempted traditional pvc pipe worker method increase engineering cost.The antiseepage, the reinforcing that are widely used in building foundation in traffic, civil engineering, national defence and the water conservancy isolith geotechnique journey are handled, and are applicable to the high pressure vectored injection grouting works in shallow bore hole, the quicksand stratum.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of guard aperture device comprises grout pipe 16, job platform 13, rotating disk 12, slips 11, adapter sleeve 9, floral tube 15, guard aperture sleeve pipe 17 and shower nozzle 18.Described rotating disk 12 is fixed on the job platform 13, and rotating disk 12 is connected on same axis with slips 11.Described floral tube 15 is laid with many row's plasma discharges hole 14, and guard aperture sleeve pipe 17 is installed in below the floral tube 15, and by being threaded.Guard aperture sleeve pipe 17 is equipped with the long key 10 of guide-localization with floral tube 15 outer walls, and its long key 10 in location welds piecemeal with guard aperture sleeve pipe 17 and floral tube 15 respectively, and the guard aperture sleeve pipe between every section, floral tube are to be threaded.Grout pipe 16 is triple grout pipes or double grout pipe, and grout pipe 16 is packed in the floral tube 15 guard aperture sleeve pipes 17, and grout pipe 16 is connected with floral tube 15 by adapter sleeve 9, and on same axis, shower nozzle 18 is threaded with grout pipe 16 lower ends.Described shower nozzle 18, grout pipe 16 and floral tube 15 and guard aperture sleeve pipe 17 promote grout pipe 16 with hoist engine, and under the location of the long key 10 of the guiding of slips 11 and location and rise or decline by speed of setting and direction, also can rotate, constitute the guard aperture device with the rotation of rotating disk 12.
Operating principle
After importing high mud jacking (water) 8 and low pressure gas 6 from grout pipe 16 tops, shower nozzle 18 cuts jet grouting to stratum soil 2 immediately in boring 1; The unnecessary cement paste in the boring 1 and the mixed serum of stratum soil rise to ground more than 3 via the annular space 4 between grout pipe and guard aperture sleeve pipe and floral tube, are discharged by the plasma discharge hole on the floral tube 15 14 and return slurry 5, and unnecessary gas 7 is got rid of by grout pipe 16 tops.
