Description
The technical field is as follows:
the utility model belongs to the technical field of the colliery is strutted and specifically relates to a slip casting anchor rope is with only thick liquid device.
Background art:
the grouting anchor cable is also called as a grouting anchor rod and is an essential part in coal mine support. The grout stopping effect is an important index for evaluating the quality of a grouting anchor cable product, and the quality of the grout stopping effect directly influences the use quality of the grouting anchor cable.
In order to improve the grout stopping effect and enable the design of a grouting anchor cable product to be more reasonable and tend to be perfect, various attempts are made in the prior art to try to enable the overall structure of the product to be more reasonable. At present, the use of rubber grout stop plugs for grout stop on grouting anchor cables is widely accepted, so the improvement of the prior art mainly focuses on the improvement of the rubber grout stop plugs, and the structural forms of the existing rubber grout stop plugs are mainly two, one is integrally formed conical rubber grout stop plugs, such as application numbers: CN201910773062.9, the patent of a sealing device for a hollow grouting anchor cable in a surrounding rock crushing zone and a sealing method thereof specifically discloses a tapered rubber grout stop plug, when in use, the grout stop plug and an assembly thereof are sleeved on the grouting anchor cable (rod), then the grout stop plug and the grouting anchor cable (rod) are stirred together into a drilled hole to play a role in grout stop, and the tapered rubber grout stop plug is further improved based on, for example, a protrusion is arranged on the outer wall of the grout stop plug to increase the friction resistance; the other is a rubber grout stop plug formed by combining a plurality of components, for example, the patent with the application number of CN201621440152.4 and the patent name of multiple grout stop plugs for grouting anchor cables discloses a grout stop plug formed by combining three sections of rubber structures, and the structure further improves the grout stop effect.
The improvement and innovation of the prior art improves the grout stopping effect to a certain extent, but still has some unsatisfactory points. Research and analysis show that the root cause of the existing grout stopping plug is that the existing grout stopping plug is mainly made of rubber materials with certain hardness, the external shape of the grout stopping plug is regular and round, and although a grouting hole is approximately round as a whole, the edge of the hole is uneven and cracks and/or cracks also exist, so that the flexibility and the softness deformation of the rubber grout stopping plug cannot meet the requirement of being completely attached and extruded to the edge of the hole and the cracks and/or cracks on the hole, particularly, the pressure of grout is very high during grouting, the grout is easy to seep along the cracks or the places where the grout stopping plug is not tightly extruded to the hole, and finally, the grout stopping effect is not ideal. However, if the grout stopper is made of a material such as cloth, although the material meets the requirements on flexibility and soft deformation, the grout stopper has the defects of insufficient structural strength, easy falling off and/or slurry permeation, so that the grout stopper can be made of a harder rubber material compared with the cloth.
