Detailed Description

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a solution cavity slip casting pipe with infiltration makes up function, include slip casting pipe body 1 and set up the solution cavity slip casting hole 11 at slip casting pipe body 1 lateral wall, 1 outer wall of slip casting pipe body is equipped with the supporting component 2 that is used for carrying out the support to slip casting pipe body 1, supporting component 2 includes slip support sleeve 21, support cover 22 and the fixed plate 23 that is used for carrying out the location to slip support sleeve 21, be equipped with in the slip support sleeve 21 and be used for carrying out the row's material shutoff subassembly 3 of shutoff to solution cavity slip casting hole 11, it includes the shutoff ball 31 that is used for carrying out the shutoff to solution cavity slip casting hole 11 to arrange material shutoff subassembly 3, mount pad 32 and extrusion spring 33.

In this embodiment: the grouting pipe body 1 is inserted into a preset hole by an operator, grout is injected into the grouting pipe body 1 by an external grouting device and is discharged outwards from a karst cave grouting hole 11, the grouting pipe body 1 can be supported by arranging a sliding support sleeve 21 and a support sleeve 22 so as to prevent the grouting pipe body 1 from contacting with the inner wall of the preset hole, therefore, after the grouting pipe body 1 contacts with the inner wall of the hole under the action of gravity, the inner wall of the hole blocks the karst cave grouting hole 11, the smoothness of the karst cave grouting hole 11 is ensured, along with the progress of grouting work, the operator needs to draw the grouting pipe body 1 outwards, in the process that the grouting pipe body 1 is drawn outwards, the grouting pipe body 1 and the inner wall of the support sleeve 22 slide relatively, meanwhile, a blocking ball 31 and the grouting pipe body 1 generate relative displacement until the karst cave grouting hole 11 moves to the position corresponding to the blocking ball 31, the shutoff ball 31 outwards pops out under extrusion spring 33's effect, thereby carry out the shutoff to solution cavity injected hole 11, when the length that injected pipe body 1 was taken out is longer, injected pipe body 1 continues outwards to be taken out, shutoff ball 31 extrudes extrusion spring 33 shrink under the pressure action, along with the removal of injected pipe body 1, solution cavity injected hole 11 coincides once more with the position of shutoff ball 31, shutoff ball 31 blocks solution cavity injected hole 11 once more, a plurality of shutoff balls 31 correspond different solution cavity injected hole 11, can block a plurality of solution cavity injected holes 11 simultaneously, thereby avoid the thick liquid outwards to discharge in the solution cavity injected hole 11 of taking the position out, thereby avoid the waste of thick liquid.

The supporting sleeve 22 is fixedly connected to the inner wall of the sliding supporting sleeve 21, the supporting sleeve 22 is slidably connected with the grouting pipe body 1, and the fixing plate 23 is fixedly connected to the outer wall of the sliding supporting sleeve 21; support cover 22 and fix the inner wall at sliding support sleeve 21, sliding support sleeve 21 can support cover 22, thereby make support cover 22 can support slip casting pipe body 1, and support cover 22 through setting up and can make and leave certain space between slip casting pipe body 1 and the sliding support sleeve 21 inner wall, thereby can be convenient for arrange the installation of material shutoff subassembly 3, fixed plate 23 passes through fixing device and fixes outside the hole of predetermineeing, fix fixed plate 23 by the staff, thereby improve the stability of device in the use.

The mounting seat 32 is fixedly connected to the inner wall of the sliding support sleeve 21, one end of the extrusion spring 33 is fixedly connected with the mounting seat 32, the other end of the extrusion spring 33 is fixedly connected with the plugging ball 31, and the diameter of the plugging ball 31 is larger than the aperture of the karst cave grouting hole 11; blocking ball 31 can stretch out mount pad 32 and carry out the shutoff to solution cavity slip casting hole 11 under extrusion spring 33's elastic action, thereby can avoid the thick liquid to discharge from solution cavity slip casting hole 11 outwards, blocking ball 31's diameter is greater than the aperture of solution cavity slip casting hole 11, thereby make blocking ball 31 carry out the shutoff to solution cavity slip casting hole 11 when, blocking ball 31's part still can expose in the outside, when the relative blocking ball 31 motion of slip casting pipe body 1, blocking ball 31 can break away from in the solution cavity slip casting hole 11 by the effort, avoid blocking ball 31 to stretch into completely in the solution cavity slip casting hole 11 and cause the hindrance to the motion of slip casting pipe body 1.

One end of the sliding support sleeve 21 is fixedly connected with a scraper 211, and the scraper 211 is contacted with the outer wall of the grouting pipe body 1; the in-process of taking out outward of slip casting pipe body 1, scraper blade 211 inner wall and the contact of slip casting pipe body 1 outer wall, along with the motion of slip casting pipe body 1, scraper blade 211 can clear up the thick liquid of the adhesion of slip casting pipe body 1 outer wall to reduce the amount of the thick liquid that gets into the inside of slip support sleeve 21, avoid the thick liquid to solidify in slip support sleeve 21 and cause the hindrance to the relative motion of slip casting pipe body 1 and slip support sleeve 21.

A limiting groove 321 for limiting the plugging ball 31 is formed in one side of the mounting seat 32 away from the sliding support sleeve 21; can carry on spacingly to the shutoff ball 31 when stepping down the shutoff ball 31 through setting up spacing groove 321, when slip casting pipe body 1 motion, the shutoff ball 31 can receive horizontal effort, can avoid the shutoff ball 31 to receive horizontal effort through setting up spacing groove 321 and take place lateral shifting.

The utility model discloses a theory of operation and use flow: the sliding support sleeve 21 is sleeved on the outer wall of the grouting pipe body 1, a worker inserts the sliding support sleeve 21 into a hole which is arranged in advance, a fixing plate 23 is fixed on a rock wall through a fixing device, the grouting pipe body 1 is inserted into the sliding support sleeve 21 by the worker, grout is injected into the grouting pipe body 1 through an external grouting device and is discharged outwards through the karst cave grouting hole 11, in the grouting process, the sliding support sleeve 21 and the support sleeve 22 can support the grouting pipe body 1, so that the blockage of the karst cave grouting hole 11 after the grouting pipe body 1 is contacted with the inner wall of the hole is avoided, the grouting efficiency is prevented from being influenced after the karst cave grouting hole 11 is blocked, when the grouting pipe body 1 needs to be drawn out for a part of length, the blocking ball 31 corresponds to the karst cave grouting hole 11 along with the relative movement of the grouting pipe body 1 and the sliding support sleeve 21, the blocking ball 31 pops out under the action of the extrusion spring 33, can block the karst cave grouting hole 11, and grout can not be discharged outwards from the blocked karst cave grouting hole 11, so that the discharge of the karst cave grouting hole 11 at the part where the grout is pumped out in the grouting process is avoided.
