Abstract
The invention discloses a grout plugging yielding tray for a grouting anchor rod or anchor cable and a usage method thereof. The grout plugging yielding tray is composed of an upper portion and a lower portion, wherein the upper portion is a butterfly-shaped tray body for yielding, the lower portion is a horn-head-shaped tray body for plugging grout, and the horn-head-shaped tray body and the butterfly-shaped tray body are fastened together up and down to form the grout plugging yielding tray. The small hole diameter of the horn-head-shaped tray body and the small hole diameter of the butterfly-shaped tray body are matched with the outer diameter of an anchor rod body or an anchor cable body. The grout plugging yielding tray plugs rock holes and plays a role in plugging grout of a grouting plug, so that grout bodies cannot spill from orifices during grouting, the grouting pressure and the grouting effect are guaranteed, rubber plugs are saved; and when surrounding rock deforms, the butterfly-shaped tray yields firstly, a horn-head-shaped component yields continuously after the butterfly-shaped tray yields to limitation, a continuous yielding effect is achieved, the yielding time is long, the yielding range is large, and a good anchoring effect is provided for a roadway.
Description
Technical field
The present invention relates to that mine working, roads and tunnels, water conservancy culvert support engineering use grouted anchor bar and anchor cable.
Background technology
At present, grouted anchor bar and anchor cable have been used in large quantities in engineerings such as mine timbering, roads and tunnels supporting, the supporting of water conservancy culvert, massif reinforcing, building pile foundation reinforcings, grouted anchor bar (rope) is comprised of anchor pole (rope) body, pallet and nut, slurries can be injected unconsolidated rock by injected hole, thereby anchor bar body is combined into one with country rock effectively, improves the purpose of country rock carrying self pressure.Above-mentioned pallet has plate shaped and butterfly; The deficiency of plate shaped pallet is, can not play the pressure effect that allows when country rock generation large deformation, and slurry easily overflows from the aperture during slip casting, causes grouting pressure not enough, do not reach slip casting effect, and the method that can only take to add rubber stopper that has is blocked the aperture; Though butterfly-shaped dish has solved the pressure problem that allows, exist equally slurry from the aperture overflow problem, do not reach slip casting effect, and single butterfly-shaped dish make the pressure effect limited, can not continue to allow pressure.
Summary of the invention
The purpose of this invention is to provide a kind of cost low, easy for installation, both possessed and continued to allow the pressure effect, have again the grouted anchor bar of stifled slurry effect or stifled slurry that anchor cable is used and allow the pressure pallet, the using method of this pallet is provided simultaneously.
Stifled slurry of the present invention allows the technical scheme of pressing pallet to take be:
The stifled slurry that a kind of grouted anchor bar is used allows the pressure pallet, it is characterized in that, it is comprised of two parts up and down, its middle and upper part is divided and is one and plays and allow the butterfly shape disk body of pressure effect, lower part is a horn-like disk body that plays stifled slurry effect, loudspeaker head disk body and butterfly-shaped disk body snap together up and down, common consist of stifled slurry and allow the pressure pallet; The osculum bore of the osculum bore of loudspeaker head disk body and butterfly shape disk body all matches with the external diameter of anchor rod body.
The stifled slurry that a kind of grouting cable anchor is used allows the pressure pallet, it is characterized in that, it is comprised of two parts up and down, its middle and upper part is divided and is one and plays and allow the butterfly shape disk body of pressure effect, lower part is a loudspeaker head disk body that plays stifled slurry effect, loudspeaker head disk body and butterfly shape disk body snap together up and down, common consist of stifled slurry and allow the pressure pallet; The osculum bore of the osculum bore of loudspeaker head disk body and butterfly shape disk body all matches with the external diameter of anchor cable body.
In order to make pallet continue to allow pressure, the compressive strength of loudspeaker head disk body is greater than the compressive strength of butterfly shape disk body.
The stifled slurry of the present invention allows the using method of pressing pallet, it is characterized in that, drilling on rock, anchor pole or anchor cable are installed in the boring, on the exposed junction after anchor pole or anchor cable are installed in rock-boring, at first put stifled slurry of the present invention and allow the pressure tray body, wherein osculum one end of loudspeaker head disk body stretches in the boring it towards boring, and then the nut of screwing on, and applies pretightning force, the osculum of loudspeaker head disk body is pressed in the boring gradually, thus tightly block the aperture.
Operating principle of the present invention and good effect are:
1, skyhook or anchor cable tighten in the process of nut, and nut and pallet are in contact with one another, and pallet is produced the axial compression effect, part is compressed distortion on the pallet, and whole anchor pole is worked the pressure effect that allows, and lower part is clamp-oned in the petrosal foramen, block petrosal foramen, play the stifled slurry of grouting plug;
2, along with part on the pallet constantly is compressed distortion, the osculum of horn-like disk body is more and more tightr with contacting of petrosal foramen, and slurry overflows from the aperture when thoroughly stopping slip casting, has guaranteed grouting pressure and slip casting effect, not only saved rubber stopper, and the obstruction effect is far superior to rubber stopper.
2, when country rock deforms, butterfly-shaped disk body at first allows pressure, allow be pressed onto the limit after, horn-like disk body then allows pressure, plays to continue to allow the pressure effect, makes the pressure time long, makes the pressure scope large, and good anchorage effect is played in the tunnel.
Description of drawings
Fig. 1 is the front view of the embodiment of the invention when using, among the embodiment take anchor pole as example.
Among the figure: 1-butterfly shape disk body, 2-loudspeaker head disk body, 3-nut, 4-rock, 5-anchor rod body, 6-boring.
A represents the height of loudspeaker head disk body; B represents the height of butterfly shape disk body; C represents the internal diameter of pallet of the present invention; D represent pallet of the present invention external diameter.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
Fig. 1 is take the grouted anchor bar that adopts diameter 25mm as example, and bore diameter is 28mm.The stifled slurry that grouted anchor bar is as shown in Figure 1 used allows the pressure pallet, it is comprised of two parts up and down, its middle and upper part is divided and is one and plays and allow the butterfly shape disk body 1 of pressure effect, lower part is a loudspeaker head disk body 2 that plays stifled slurry effect, loudspeaker head disk body 2 and butterfly shape disk body 1 snap together up and down, common consist of stifled slurry and allow the pressure pallet; The osculum bore of the osculum bore of loudspeaker head disk body 2 and butterfly shape disk body 1 all matches with the external diameter of anchor rod body 5.
Among the embodiment, the high a=80mm of loudspeaker head disk body 2, the high b=60mm of butterfly shape disk body, internal diameter c=28mm, the external diameter=100mm of whole pallet.
In order to make pallet continue to allow pressure, the compressive strength of loudspeaker head disk body 2 is greater than the compressive strength of butterfly shape disk body 1.
During use, it is drilling 6 on rock 4, anchor pole 5 is installed in the boring 6, on the exposed junction after anchor pole 5 is installed, at first put stifled slurry of the present invention and allow the pressure pallet, wherein osculum one end of loudspeaker head disk body 2 stretches in the boring 6 it towards boring 6, and then the nut 3 of screwing on, apply pretightning force, the osculum of loudspeaker head disk body 2 be pressed in the boring 6 gradually, thus tightly block hell.
