Abstract
The utility model discloses a movable grouting device, comprising a hollow drill pipe, wherein the hollow drill pipe is externally sleeved with a casing, a supported flange is connected with a left sealing member via the left end of the casing, a right end of the casing is equipped with a quick separator, and a grout return joint is communicated with the casing; the left sealing member is a multilayer V-shaped rubber sealing ring; in the quick separator, a female flange is connected with the right end of the casing through a lower flange case, a right sealing member is arranged between the lower flange case and the right end of the casing, and a movable pin shaft is matched with the female flange via a bolt. The movable grouting device with convenient, fast installation and disassembly realizes free lifting and rotation of grout jetting drill pipe in case of no pressure release in high pressure grouting, and simultaneously, grout can be circulated so as to guarantee the continuity of grouting process and construction quality, reduce possibility of down hole accident and lower labor intensity. By selecting the multilayer V-shaped rubber sealing ring as the left sealing member, the sealing effect in the process of high-pressure grouting is guaranteed.
Description
Technical field
The utility model relates to a kind of provisions for grouting, particularly a kind of movable filling device.
Background technology
What high pressure grouting of the prior art was adopted is the method for " small diameter hole, aperture sealing, high pressure grouting ", its aperture locking device generally adopts rotation gland or screw mandrel and compression glueballs, expand to realize the aperture sealing by glueballs, in use do not make glueballs shrink reduction as if not unscrewing gland or screw mandrel, Grout-jetting pipe can't rotate in the hole, if the removal aperture is blocked to rotate Grout-jetting pipe, grouting pressure will be let out and is kept to zero, cause artificial interruption grouting, influence grouting quality; Discover, the part rock mass, the vein that grow very much in particularly fine crack is inhaled the slurry rate and is greatly reduced, even occurs not inhaling the slurry phenomenon after recovering grouting, cause human accident to irritate section.In addition, people's inertia also often causes regularly the removal aperture to be blocked, and causes the prolongation along with grouting time, and in the hole, particularly in the deep hole, slurry flow rate is crossed deferred living precipitation and flocculation produces the holding tube phenomenon, causes the generation of drilling accident.
Summary of the invention
Technical problem to be solved in the utility model provides the movable efficiently filling device of a kind of installation, convenient disassembly, overcome conventional aperture locking device and realized the deficiency of aperture closing process by pressing the glueballs that expands, not pressure release just can guarantee to penetrate the slurry drilling rod in high pressure grouting free lifting and rotation have been realized, slurries are capable of circulation simultaneously, the continuity and the construction quality of grouting process have been ensured, reduce the drilling accident odds, reduced labour intensity.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of movable filling device comprises hollow drill, hollow drill is with housing outward, supported flange is connected with left seal by the housing left end, and the housing right-hand member is equipped with quick chorista, and the overfall joint is communicated with housing.
Left side seal is a multilayer V-type rubber seal.
In the chorista, the flange of trough of belt is connected with the housing right-hand member by the lower flange cover fast, is provided with right seal between lower flange cover and the housing right-hand member, and removable bearing pin matches with the flange of trough of belt by bolt.
The movable filling device that the utility model provides, beneficial effect is as follows: 1, owing to adopt hollow drill, the hollow drill left end is communicated with the rig kelly, the hollow drill right-hand member is communicated with hole injection slurry drilling rod, the lifting of rig kelly and rotation, driving hole injection slurry drilling rod by hollow drill promotes in the hole and rotates, supported flange is connected with left seal by the housing left end, slurries in the high pressure grouting process are sealed, not pressure release just can guarantee to penetrate the free lifting and the rotation of slurry drilling rod in high pressure grouting, the continuity and the construction quality of grouting process have been ensured, avoid the drilling accident that produces because of hole entoplasm liquid precipitate holding tube and sealed the phenomenon of being irritated sector hole wall crack, reduce the drilling accident odds, reduced labour intensity; Fast chorista makes installation of the present utility model, convenient disassembly quick, has alleviated workman's work workload; The overfall joint is communicated with housing makes slurries to be drawn out of through housing, realizes cycling repeatedly, has avoided slurries to pollute field ground simultaneously, has protected environment.
2, selecting multilayer V-type rubber seal for use is left seal, has the effect of " self-styled ", tightr with sealed applying under the pressuring action of supported flange, has guaranteed the sealing effectiveness in the high pressure grouting process.
3, fast in the chorista, the lower flange cover can make things convenient for the orifice sleeve of all size and is connected, and adapts to the boring needs in different apertures, and removable bearing pin matches with the flange of trough of belt by bolt and realized that installation of the present utility model, convenient disassembly are quick.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples: Fig. 1 is a structural representation of the present utility model; Fig. 2 is a right view of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises hollow drill 8, the hollow drill 8 outer housings 9 that are with, and supported flange 2 is connected with left seal 3 by housing left end 10, and housing right-hand member 11 is equipped with quick chorista, and overfall joint 5 is communicated with housing 9.
Fast in the chorista, the flange 14 of trough of belt is connected with housing right-hand member 11 by lower flange cover 6, lower flange overlap 6 and housing right-hand member 11 between be provided with right seal 12, removable bearing pin 4 matches with the flange 14 of trough of belt by bolt 13.
The installation of the present utility model and the course of work are as follows: orifice sleeve is installed on drilling orifice, lower flange cover 6 is threaded with orifice sleeve, hollow drill left end 1 is communicated with the rig kelly, hollow drill right-hand member 7 stretched in the drilling orifice with hole injection slurry drilling rod be communicated with, housing right-hand member 11 is inserted in the lower flange cover 6 and with lower flange cover 6 closely to be contacted, the flange 14 of trough of belt is installed on lower flange cover 6, in groove, insert removable bearing pin 4, the utility model sealing can be installed on the aperture by the fastening of bolt 13.
During use, be communicated with agitator again after can connecting the overfall measuring instrument in the outlet of overfall joint 5, start rig, the lifting of rig driving lever and rotation drive the lifting and the rotation of hole injection slurry drilling rod by hollow drill, slurries enter in the hole injection slurry drilling rod by hollow drill simultaneously and finish the grouting operation, unnecessary slurries then flow in the overfall joint 5 by the space between housing 9 and the hollow drill 8 and are drawn out of, and return in the agitator for recycling.
During dismounting, only need looser a bolt 13, take off removable bearing pin 4, unload the flange 14 of trough of belt, can will pull down except that the member that lower flange overlaps 6.
