Preferably, the sealing device comprises three rubber rings and four first gaskets, the rubber rings and the first gaskets are alternately sleeved outside the threading pipe, and when the rubber rings are extruded, the rubber rings deform and expand, the diameter of the rubber rings is increased to the extrusion grouting holes, and therefore the sealing effect is achieved.
Further preferably, the second gasket is sleeved between the annular sleeve wrench and the extrusion pipe, so that the problem of abrasion between the annular sleeve wrench and the extrusion pipe is solved, the second gasket is directly replaced after being abraded, a part of downward extrusion force from the annular sleeve wrench can be buffered by the second gasket, and the cleaning component is conveniently detached when the annular sleeve wrench and the extrusion pipe are separately installed.
Further preferably, the annular sleeve wrench and the extrusion pipe are integrally formed, so that the problem of abrasion caused by friction between the annular sleeve wrench and the extrusion pipe is solved, the cost of replacing parts is reduced, and the parts are convenient to install due to the integral forming of the annular sleeve wrench and the extrusion pipe.
Further preferably, the extrusion pipe, the first gasket and the second gasket are made of Q235 galvanized steel, so that the device effect is prevented from being influenced by rusting and aging.
Further preferably, the anticreep end adopts the nut, and the screw thread of annular cover spanner and nut is revolved to opposite, prevents that annular cover spanner from making the nut drop through closing device when extruding extremely down, influences the anticreep effect of nut.
Preferably, the outer diameter of the first gasket is smaller than the outer diameter of the second gasket, so that the outer diameter of the first gasket is prevented from influencing the expansion effect of the rubber ring.
Further preferably, the ring sleeve wrench is integrally formed by a ring sleeve and two round rods, the two round rods are symmetrically arranged on two sides of the outer wall of the ring sleeve, the structure is firm and simple, and the ring sleeve wrench is convenient to use by two hands.

The device has the characteristics of feasible technology, simple principle, convenient installation and disassembly, compact grouting, low manufacturing cost and the like, and is a mechanical cement grouting plug device with practicability.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
as shown in fig. 1, a mechanical cement grouting plug device mainly comprises an extrusion device 1, a sealing device 2 and a threading pipe 3.
The extrusion device 1 is composed of an annular sleeve wrench 12 and an extrusion pipe 11, wherein the annular sleeve wrench 12 rotates through a rotating wrench to move up and down on the threading pipe 3, and downward force is generated during movement and acts on the extrusion pipe 11.
The bottom end of the threading tube 3 is provided with an anti-drop end 5, the anti-drop end 5 adopts a nut, and the thread turning directions of the annular sleeve wrench 12 and the nut are opposite.
The sealing device 2, the extrusion pipe 11 and the annular sleeve wrench 12 are sequentially sleeved outside the threading pipe 3 from bottom to top, and the grouting joint 6 is installed at the top of the threading pipe 3.
The ring-shaped sleeve wrench 12 is formed by integrally forming a ring sleeve and two round rods, the two round rods are symmetrically arranged on two sides of the outer wall of the ring sleeve, the round rods are held by two hands to rotate, and when the ring-shaped sleeve wrench 12 rotates, the extrusion pipe 11 can be driven to move downwards to extrude the sealing device 2.
The sealing device 2 comprises three rubber rings 21 and four first gaskets 22, the rubber rings 21 and the first gaskets 22 are alternately sleeved outside the bushing pipe 3, and the outer diameter of the first gaskets 22 is smaller than that of the second gaskets 4.
