Abstract
The utility model discloses a novel grouting hole packer which consists of a grouting conduit, an expansion conduit, a clamp hoop and a connector. The connector is connected at the outlet end of the grouting conduit, the expansion conduit is sleeved on the outer side of the grouting conduit, the clamp hoop tightly sealed with the grouting conduit is arranged on the expansion conduit, a small hole is formed on a grouting conduit wall to form a hole channel communicated with the expansion conduit, a rubber non-return sleeve is arranged on the outer side of the hole channel, and an aluminum foil is arranged between the connector and the grouting conduit. Preferably, the grouting conduit and the connector are made from engineering plastics. The novel grouting hole packer has the advantages that the novel grouting hole packer is a disposable material, can be left in coal and is not required to be removed, and an engineering plastic product does not produce spark during cutting, so that the materials are saved, manufacture is convenient and simple, and the work safety is greatly improved.
Description
Technical field
The utility model relates to a kind of hole packer structure, relates in particular to a kind of novel slurry filling hole packer that can be used for coal-face under the mine.
Background technology
A lot of hole sealing devices and method for sealing are arranged in the coal mine work area construction operation, and polyurethane sealing of hole method is adopted in more common expansion type hole packer, the gas drainage under suction of adopting when the water filling operation is arranged.Hole packer during the water filling operation generally can be reused, the bore diameter during gas drainage under suction generally big, boring is less, polyurethane foams expand solid pipe and the sealing of holes of adopting during sealing of hole more.Need carry out grouting and reinforcing when work plane is met loose coal or roof collapse, and the material that is used for reinforcing mostly is the polymer chemistry injecting paste material, this material mostly is two components, reaction is fast, intensity is high.With this understanding, traditional hole packer is steel pipe because of its center grouting pipe, should not reside in coal body, easily produce spark during cutting, certain danger is arranged, and the chemical pulp adhesive strength is higher under the environment of high gas, high dust, solidifies very fast, therefore easy to clean not after the use is not suitable for reusing.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of reasonable in design, sealing of hole is effective, cost is low, easy to use novel slurry filling hole packer, by the improvement to hole packer material and structure, solved under high gas, the many dust atmospheres, slip casting is difficult to clear up and the easy problem that produces spark of coal-winning machine cutting.
To achieve these goals, technical solution adopted in the utility model is:
A kind of novel slurry filling hole packer, by grouting pipe, inflation catheter, clip, joint is formed, joint is connected the port of export of grouting pipe, inflation catheter is enclosed within the grouting pipe outside, inflation catheter is provided with the clip with the sealing of grouting pipe banding, has aperture on the described grouting pipe tube wall, forms the duct with inflation catheter UNICOM.
Described duct arranged outside has rubber non-return sleeve pipe.
Be provided with aluminium foil between described joint and the grouting pipe.
As preferably, grouting pipe and joint material are engineering plastics.
The beneficial effects of the utility model: the material that the utility model provides is disposable material, can stay in the coal, does not need cleaning, and engineering plastic product can not produce spark when cutting, both saved material, easy to make simple, improved the safety of working greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of novel slurry filling hole packer as shown in Figure 1, by grouting pipe 1, inflation catheter 2, clip 3, joint 7 is formed, joint 7 is connected the port of export of grouting pipe 1, inflation catheter 2 is enclosed within grouting pipe 1 outside, inflation catheter 2 is provided with the clip 3 with the sealing of grouting pipe 1 banding, have aperture on described grouting pipe 1 tube wall, form the duct 5 with inflation catheter 2 UNICOMs, described duct 5 arranged outside have rubber non-return sleeve pipe 4, are provided with aluminium foil 6 between described joint 7 and the grouting pipe 1.
Slip casting work begins, grouting pump slurries by hole packer entrance pressure injection in the grouting pipe 1 of hole packer, because grouting pipe 1 port of export is stopped by aluminium foil 6 sealings, slurries can not pass through hole packer, slurries are by the duct 4 on the grouting pipe 1, break through rubber non-return sleeve pipe 4, flow in the space between grouting pipe 1 and the inflation catheter 2, and rubber non-return sleeve pipe 4 can stop slurry reflux, inflation catheter 2 is along with the rising of pressure is expanded gradually, produce the extruding of full section with the injected hole hole wall and contact, thereby the aperture that makes injected hole is by shutoff; Compress when inflation catheter 2 expansions and with the injected hole hole wall, grouting pressure will raise in the hole packer, and when grouting pressure surpassed certain force value, slurries broke through aluminium foil 6 and inject in the injected hole, beginning slip casting operation.
The material that the utility model provides is disposable material, can stay in the coal, does not need cleaning, and engineering plastic product the time can not produce spark in cutting, has both saved material, and is easy to make simple, improved the safety of work greatly.
