Technical field
The utility model relates to the osmotic pressure measuring equipment that the permeability test of rock mass original position high pressure water injection is carried out in fields such as being used for Hydraulic and Hydro-Power Engineering, water supply project, petroleum engineering, especially the osmotic pressure measuring equipment that uses when higher at the rock mass osmotic pressure.
Background technology
Under the prior art condition, general simple employing modified cement mortar in osmotic pressure hole or modified water mud carry out the technology of grout sealing in the high pressure water injection test.The shortcoming of this technology is to be easy to cause osmometer to be tied by follow-up priming charge mud sol in the filling process, causes the inefficacy of osmometer, does not reach effective measurement effect of osmotic pressure, and its construction quality is difficult to guarantee.Simultaneously, because an osmometer is only installed in a certain position in the rock mass, after very appearance caused osmometer to lose efficacy, this osmotic pressure hole osmotic pressure measured the consequence of utter failure.
The utility model content
The technical problems to be solved in the utility model is that the deficiency at existing osmotic pressure measurement technology exists provides a kind of osmotic pressure measuring equipment that is used for the high pressure water injection pilot system that can effectively guarantee osmometer installation quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of osmotic pressure measuring equipment that is used for the high pressure water injection pilot system, it comprises the osmotic pressure hole that is opened in the rock mass, one end of one weldless steel tube stretches into bottom, osmotic pressure hole, one osmometer is fixed on the bottom of this weldless steel tube, its osmometer cable passes weldless steel tube and reaches beyond the osmotic pressure hole, and the osmometer cable exit of this weldless steel tube adopts the shutoff of epoxy resin plug; More than weldless steel tube one end of fixing osmometer, the floral tube section that is laid with the limbers on it is set, weldless steel tube arranged outside one rubber separator that the floral tube section is above, colligation sealing sea-tangle above the rubber separator; One Grouting Pipe also is installed in the osmotic pressure hole, and this Grouting Pipe extend into sealing sea-tangle place; The sealing sea-tangle in osmotic pressure hole is above to carry out shutoff by the pure slurry of Grouting Pipe injection micro-expansion cement slurry formation expansive cement block section, adopts the sand-cement slurry plug shutoff that is formed by the micro-expansion cement mortar at the aperture in distance osmotic pressure hole environs; One gas outlet also is installed in the osmotic pressure hole in addition, and this gas outlet extend into place, the pure slurry of expansive cement block section.
Further improvement of the utility model is that weldless steel tube also is connected with tensimeter and drainage exhaust switch beyond the aperture in this osmotic pressure hole.
Of the present utility model anotherly further be improved to, the outside of this osmometer coat the protection sand pocket.
Of the present utility modelly one further improve this again, this floral tube section is that 20CM is long, and this sealing sea-tangle is that 100CM is long, and this rubber separator is arranged on the above 15CM of this floral tube section place.
Compared with prior art, the beneficial effects of the utility model are: the utility model passes through to adopt fixedly osmometer of weldless steel tube, thereby not only is convenient to the accurate installing and locating of osmometer position, has also made things convenient for the installation of tensimeter and drainage exhaust switch; By the setting of rubber separator and sealing sea-tangle, can effectively osmometer and follow-up priming charge mud be separated, play the effect of protection osmometer; By measure the water pressure in the weldless steel tube at the aperture of weldless steel tube setting pressure table, can play osmotic pressure and measure the contrast effect, and can measure achievement with osmometer and verify mutually, the osmotic pressure of avoiding osmometer to lose efficacy causing is measured failure.Generally speaking, the utility model technological design is reasonable, and is simple and reliable for structure, easy to operate, and can not cause damage to osmometer and lead in the utility model installation and the shutoff process, can guarantee the reliability of measuring sensor effectively.

Embodiment
As shown in Figure 1, the utility model comprises that an end that is opened in 16, the weldless steel tubes 12 in osmotic pressure hole in the rock mass stretches into 16 bottoms, osmotic pressure hole.An osmometer 8 is fixed on the bottom of weldless steel tube 12, and its cable 15 passes weldless steel tube 12 and reaches beyond the osmotic pressure hole 16, and the outside of this osmometer 8 coats protection sand pocket 9.The long floral tube section 10 of 20cm is set more than weldless steel tube 12 1 ends of fixing osmometer 8, and promptly this floral tube section 10 is provided with the inside and outside limbers 17 that connects, and makes the outer water bodys connection of the inner and osmometer of weldless steel tube 8.Arranged outside one rubber separator 11 at the floral tube section 10 above 15cm places of weldless steel tube; begin upwards colligation sealing sea-tangle 7 in the 100cm scope from rubber separator 11; thereby can effectively osmometer 8 and follow-up priming charge mud be separated, play the effect of protection osmometer 8.One Grouting Pipe 4 also is installed in the osmotic pressure hole 16, and this Grouting Pipe 4 extend into sealing sea-tangle 7 places.It is that 0.01% micro-expansion cement slurry forms the pure slurry of expansive cement block section 6 and carries out shutoff that the sealing sea-tangle in osmotic pressure hole 16 is injected expansion coefficient by Grouting Pipe 4 more than 7, and adopting by expansion coefficient at the aperture in distance osmotic pressure hole 16 environs is cement mortar plug 5 shutoff that 0.01% micro-expansion cement mortar forms.One gas outlet 13 also is installed in the osmotic pressure hole 16 in addition, and this gas outlet 13 extend into 6 places, the pure slurry of expansive cement block section, to get rid of the air in the pure slurry of cement.Cable exit in the weldless steel tube 12 adopts 1 shutoff of epoxy resin plug, thereby can effectively avoid osmometer cable 15 is caused damage.Be connected with two threeways 14 on the weldless steel tube beyond the aperture in osmotic pressure hole 16, it connects tensimeter 3 and drainage exhaust switch 2 respectively.
