Description
Technical field
This utility model relates to colliery tunnel support field, especially a kind of stop grouting plug.
Background technology
In coal mine support, general employing stop grouting plug is positive taper at present, is sleeved on grouting cable anchor, puts into together with anchor cable
In the hole being drilled.In actual use, often occurring in installation process, the abrasion of stop grouting plug body, deformation cause destroying, because of in hole
Footpath size irregularly cannot tamp the phenomenons such as gap, the problems such as spillage, closure are the tightest occurs, has a strong impact on and only starch effect.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of stop grouting plug.
For achieving the above object, this utility model employing following technical proposals:
A kind of stop grouting plug, including stop grouting plug top and stop grouting plug bottom, described stop grouting plug top is inverted cone-shaped structure, described
Stop grouting plug bottom is column structure, and described stop grouting plug central upper portion and stop grouting plug lower central are respectively provided with anchor cable centre bore, described
Anchor cable centre bore aperture is less than anchor cable diameter, and the internal diameter of described stop grouting plug bottom is more than stop grouting plug top basal diameter and less than only
Slurry plug upper top diameter, described stop grouting plug upper top diameter is less than hole diameter, and described stop grouting plug lower outer diameter is less than hole
Hole dia, described stop grouting plug top and stop grouting plug bottom all use elastomeric material to make.
Preferably, described stop grouting plug upper portion side wall presses tapered arrangement, and the thickness of described stop grouting plug upper portion side wall is more than or equal to
2mm and less than or equal to 10mm, stop grouting plug lower sides thickness is more than or equal to 2mm, and less than or equal to 10mm.
Preferably, described anchor cable centre bore is [1mm, 5mm] with the aperture difference range of anchor cable diameter.
Preferably, described stop grouting plug upper height is less than stop grouting plug lower height.
Preferably, described stop grouting plug top and stop grouting plug bottom all use elastomeric material to make.
Preferably, described stop grouting plug bottom is hollow cylinder structure, and the inner wall thickness of stop grouting plug lower bottom end is more than only
The inner wall thickness of slurry plug lower tip.
The beneficial effects of the utility model are, this utility model achieves stop grouting plug top and stop grouting plug lower contact surface expands
, thus fill up hole space, solve slip casting closure not tight, the problem that spillage is serious.
Accompanying drawing explanation
Fig. 1 is the longitdinal cross-section diagram during this utility model uses；
Fig. 2 is stop grouting plug top plan view；
Fig. 3 is stop grouting plug bottom front view；
Wherein 1. stop grouting plug top, 2. stop grouting plug bottom, 3. grouting cable anchor centre bore.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of stop grouting plug, including stop grouting plug top 1 and stop grouting plug bottom 2, described stop grouting plug top 1 is for falling
Pyramidal structure, described stop grouting plug bottom 2 is column structure, and described center, stop grouting plug top 1 and center, stop grouting plug bottom 2 are respectively provided with
Anchor cable centre bore, described anchor cable centre bore aperture is less than anchor cable diameter, and the internal diameter of described stop grouting plug bottom 2 is more than stop grouting plug top
1 basal diameter and less than stop grouting plug top 1 end face diameter, described stop grouting plug top 1 end face diameter is less than hole diameter, described only
Slurry plug bottom 2 external diameter is less than hole diameter, and described stop grouting plug top 1 and stop grouting plug bottom 2 all use rubber elastic material to make.
Described stop grouting plug upper portion side wall presses tapered arrangement, and described stop grouting plug top 1 sidewall thickness is more than or equal to 2mm, and little
In equal to 10mm, stop grouting plug bottom 2 sidewall thickness is more than or equal to 2mm, and less than or equal to 10mm.
Described anchor cable centre bore is [1mm, 5mm] with the aperture difference range of anchor cable diameter.
Described stop grouting plug top 1 height is less than stop grouting plug bottom 2 height.
Described stop grouting plug top and stop grouting plug bottom all use elastomeric material to make.
Described stop grouting plug bottom is hollow cylinder structure, and the inner wall thickness of stop grouting plug lower bottom end is more than stop grouting plug bottom
The inner wall thickness on top.
Work process is as follows:
First, stop grouting plug top is sleeved on the grouting cable anchor body of rod peripheral, stop grouting plug top and grouting cable anchor are installed extremely
Inside hole, then stop grouting plug bottom is penetrated in grouting cable anchor, be advanced at stop grouting plug top, make stop grouting plug bottom only encase
Starch portion beyond the Great Wall, as in figure 2 it is shown, owing to stop grouting plug top and stop grouting plug bottom all use elastomeric material to make, therefore, on stop grouting plug
When portion and stop grouting plug lower contacts, contact surface can occur elastic deformation, and meanwhile, stop grouting plug top and stop grouting plug lower contact surface expand
, thus fill up hole space, solve slip casting closure not tight, the problem that spillage is serious.In actual application, on described stop grouting plug
Portion and stop grouting plug bottom are both needed to leave enough propellings and expansion distance, the advance distance on stop grouting plug top and stop grouting plug bottom
Expansion distance is equal, and scope selects between 1-5cm.
Expand, therefore, under stop grouting plug top and stop grouting plug after advancing due to stop grouting plug top and stop grouting plug lower contact surface
Portion is mutually adjacent to also and aperture wall is in close contact, simultaneously as stop grouting plug central upper portion and stop grouting plug lower central are respectively provided with anchor
Rope centre bore tightly parcel anchor cable body, therefore, stop grouting plug entirety fills up hole space, and slip casting closure is tight, only improves
Slurry efficiency.
Although detailed description of the invention of the present utility model is described by the above-mentioned accompanying drawing that combines, but not new to this practicality
The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not to pay various amendments or deformation that creative work can make still at protection model of the present utility model
Within enclosing.
