Abstract
The utility model discloses a hole packer of a grouting anchor rod. The hole packer comprises a check valve, a hole packer rod, a locking hoop, a high-pressure rubber pipe, a rubber sleeve, a reducing short connector, a gasket, a foil, a rubber sealing flat gasket and a rod. The high-pressure rubber pipe is mounted in the middle of the outside of the rod and is fastened with the middle of the outside of the rod by the locking hoop, the rubber sleeve is squeezed between the rod and the high-pressure rubber pipe, and the foil is squeezed between the gasket and the rubber sealing flat gasket. The hole packer of the grouting anchor rod has the advantages that the hole packer is assorted with the hollow grouting anchor rod during high-pressure grouting construction, a powerful hole packing effect can be realized during high-pressure grouting, and the high grouting pressure can be utilized, so that a grouting effect can be further improved, and the hole packer is stable in hole packing effect.
Description
Technical field
The utility model relates to the anchor pole field, especially relates to a kind of grouted anchor bar hole packer.
Background technology
At present, the product on the market, the hole sealing device type is more, the main mode sealing of hole that uses extruding taper block rubber, the sealing quality fluctuation is bigger, the sealing of hole reliability in the time of can't improving high-pressure slip-casting.And transformation of the present utility model, slip casting effect can further improve, and the sealing of hole effect stability also can improve the problem of hollow grouting anchor safety, improves slip casting efficient.
The utility model content
In order to overcome the defective of above-mentioned prior art, the utility model provides a kind of stable sealing of hole effect, further improves the grouted anchor bar hole packer of slip casting effect.
The utility model is realized by following scheme, a kind of grouted anchor bar hole packer, it is made up of non retern valve, the hole packer body of rod, locking clip, high-pressure rubber pipe, rubber sleeve, reducing short circuit head, pad, paillon foil, rubber seal plain cushion and the body of rod, the outer middle part of the described body of rod is equipped with described high-pressure rubber pipe, tighten together by described locking clip, be extruded with described rubber sleeve between the described body of rod and the described high-pressure rubber pipe, be extruded with described paillon foil between described pad and the described rubber seal plain cushion.
The utlity model has following beneficial effect in sum: a kind of grouted anchor bar hole packer, supporting for the construction of hollow grouting anchor high-pressure slip-casting, can play powerful sealing of hole effect during high-pressure slip-casting, can use higher grouting pressure, slip casting effect can further improve the sealing of hole effect stability.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, non retern valve; 2, the hole packer body of rod; 3, locking clip; 4, high-pressure rubber pipe; 5, rubber sleeve; 6, reducing short circuit head; 7, pad; 8, paillon foil; 9, rubber seal plain cushion; 10, the body of rod.
The specific embodiment
As shown in Figure 1, a kind of grouted anchor bar hole packer, it is made up of non retern valve 1, the hole packer body of rod 2, locking clip 3, high-pressure rubber pipe 4, rubber sleeve 5, reducing short circuit head 6, pad 7, paillon foil 8, rubber seal plain cushion 9 and the body of rod 10, the described body of rod 10 external middle parts are equipped with described high-pressure rubber pipe 4, tighten together by described locking clip 3, be extruded with described rubber sleeve 5 between the described body of rod 10 and the described high-pressure rubber pipe 4, be extruded with described paillon foil 8 between described pad 7 and the described rubber seal plain cushion 9.
In the specific implementation process: by reducing short circuit head 6 hole packer is connected with anchor pole during use; By normal step anchor pole is contained in the hole; During high-pressure slip-casting, connect high-pressure slip-casting liquid, because its pressure does not reach the inefficacy pressure of paillon foil, liquid injects between the body of rod and the high-pressure rubber pipe 4 by one group of 3mm hole under the rubber sleeve 5, thereby the big high-pressure rubber pipe that rises makes it reach powerful sealing of hole purpose.
With the increase of injecting liquid, hole wall has limited further rising greatly of sebific duct, causes pressure surge in liquid, the body of rod hole between sebific duct and the hole packer body of rod, has surpassed the failure pressure of paillon foil 8, paillon foil 8 is destroyed, and injection slurry is entered in the bolt grouting hole by reducing short circuit head 6 endoporus.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail with reference to above-mentioned the utility model of each embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
