Summary of the invention
The purpose of this utility model provides a kind of circulating top to press disabler, can realize the circulating grouting construction that utilizes rig pressure that glueballs is expanded.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: disabler is pressed on a kind of circulating top, comprise outer tube and its inner inner tube, wherein inner tube is as slurry intake channel, gap between outer tube and inner tube is as the overfall passage, the inner tube two ends are respectively equipped with tool joint and lower tool joint, and lower tool joint connects Grout-jetting pipe, and the outer tube overcoat is useful on and forms the glueballs that stops up.
Described outer tube is connected successively by outer tube macropore pipe, outer tube glueballs pipe and compressed pipe, inner tube is connected successively by pipe, inner pipe joint, cylindrical short inner tube in inner tube front tube, inner tube, in inner tube, pipe has upper tool joint near the outer race at inner pipe joint place, the top outer race of inner tube front tube has lower tool joint, wherein compressed pipe is connected to upper tool joint by interior tube edge pipe, and lower tool joint and Grout-jetting pipe are by screwed connection.
In described inner tube, pipe is fixedly connected with interior tube edge pipe by the inner tube retainer ring.
Be evenly distributed with a plurality of holes on described outer tube macropore pipe, the diameter of hole is 20mm.
Connect return pipe on the tube wall of described interior tube edge pipe.
Tighten by convex clip between interior tube edge pipe and outer tube glueballs pipe, glueballs is socketed in the outside of outer tube glueballs pipe.
The front end of described Grout-jetting pipe also is provided with cushion block, and cushion block and Grout-jetting pipe adopt and be welded to connect, and can guarantee in the grouting construction requirement, and Grout-jetting pipe is not more than the requirement of 50cm apart from foot of hole.
The utility model utilizes rig pressure that glueballs is expanded and forms obstruction, the grout hole section is sealed, and by the grouting circulating line that inner tube, outer tube, return pipe, tool joint and drilling rod Grout-jetting pipe are combined to form, after in the hole, grout compartment reaches certain pressure, just can form the flow circuit of slurries.The glueballs expansion radius of this device is larger, seal is good, be difficult for occuring the drilling accident that the slurries mudding produces, especially for the processing of soft foundation, can reduce the generation that even prevents drilling accident, effectively alleviated existing disabler construction complicated, the slurries amount of expending is large, the shortcoming that work efficiency is low.Realization of the present utility model can reduce people in work progress, material, machine expense, and to the raising of workmanship, and the control of construction speed is had remarkable benefit.Can effectively reduce the drilling accident incidence, both avoid the property resources loss, reduce engineering cost, accelerating construction progress has improved again the grouting works quality.
