Description
Technical field
The utility model relates to the supporting field of coal mine down-hole tunnel, particularly the double-deck pressure-relieving achor bar of a kind of slip casting type.
Background technology
In the supporting of coal mine down-hole tunnel, it is also one of the most frequently used support pattern that bolt support has become most important.It has, and cost is low, materials are economized, supporting effect is good and use the advantages such as flexible.In order to ensure the stability of coal mine roadway, bolt support must be carried out.But, along with China's shallow-layer coal resources are fewer and feweri, many mines have entered the deep mining stage, deep-well tunnel, soft-rock tunnel, to affect the amounts of crushing such as larger tunnel by dynamic pressure large, deformation of the surrounding rock in tunnel destroys serious, cause stress suffered by anchor pole to increase, cause the problems such as roadway bolt ruptures, supporting difficulty.
Utility model content
In order to effectively solve the problem such as roadway bolt fracture, supporting difficulty, the utility model provides the double-deck pressure-relieving achor bar of a kind of slip casting type, and its technical scheme adopted is as follows:
The double-deck pressure-relieving achor bar of a kind of slip casting type, is characterized in that: comprise base object model, immediate roof, entity coal, crossheading on lower curtate, gas prevention seepage fender, hollow slip casting anchor is locked, upper curtate goaf, penetrate slurry hole, bilayer allows pressure ring, crossheading under upper curtate, lockset, pallet, wire lath, steel band, flexible concrete spray coating, described immediate roof is positioned at the below of base object model, described entity coal is positioned at the below of immediate roof, on described lower curtate, crossheading side is adjacent with entity coal, opposite side is adjacent with gas prevention seepage fender, under described upper curtate, crossheading side is adjacent with gas prevention seepage fender, opposite side is adjacent with upper curtate goaf, the inside of described gas prevention seepage fender is provided with hollow slip casting anchor lock, described hollow slip casting anchor lock inner hollow, described hollow grouting cable anchor is arranged in hollow slip casting anchor lock, described lockset and pallet are arranged on the two ends of hollow grouting cable anchor, and pallet is in inner side, described pallet is positioned at the inside of flexible coagulation scholar spray-up.
What above-mentioned hollow slip casting anchor locked that submarginal position is processed with that bilayer allows pressure ring, bilayer allow pressure ring increase anchor pole allows pressure energy power, has both enhanced the support capacity of anchor pole, and has been improved the self-strength of anchor pole.
The both sides of above-mentioned gas prevention seepage fender are provided with wire lath; outside wire lath, steel band is installed; wire lath and steel band outside are flexible concrete spray coatings; under the protection of wire lath and steel band; caving in of gas prevention seepage fender can be prevented; flexible concrete spray coating both can have been protected and prevent gas prevention seepage fender, can fix again the position of hollow slip casting anchor lock, prevent it from offseting.
The utility model tool has the following advantages: structure is simple, operability is stronger, the double-deck pressure-relieving achor bar of slip casting type is by the double-deck effect allowing pressure ring, what can increase anchor pole allows pressure scope, prevent anchor pole to be pulled off in stress quick washing process, to deep-well tunnel and soft rock roadway support, there is far reaching significance.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model patent is described further:
As Fig. 1, shown in Fig. 2, the double-deck pressure-relieving achor bar of a kind of slip casting type of the present utility model, comprises base object model 1, immediate roof 2, entity coal 3, crossheading 4 on lower curtate, gas prevention seepage fender 5, hollow slip casting anchor lock 6, upper curtate goaf 7, penetrate slurry hole 8, bilayer allows pressure ring 9, crossheading 10 under upper curtate, lockset 11, pallet 12, wire lath 13, steel band 14, flexible concrete spray coating 15, described immediate roof 2 is positioned at the below of base object model 1, described entity coal 3 is positioned at the below of immediate roof 2, on described lower curtate, crossheading 4 side is adjacent with entity coal 3, opposite side is adjacent with gas prevention seepage fender 5, under described upper curtate, crossheading 10 side is adjacent with gas prevention seepage fender 5, opposite side is adjacent with upper curtate goaf 7, the inside of described gas prevention seepage fender 5 is provided with hollow slip casting anchor lock 6, described hollow slip casting anchor lock 6 centre positions be processed with penetrate slurry hole 8, described hollow grouting cable anchor 6 inner hollow, described lockset 11 and pallet 12 are arranged on the two ends of hollow grouting cable anchor 6, and pallet 12 is in inner side, described pallet 12 is positioned at the inside of flexible concrete spray coating 15.
Preferred hollow slip casting anchor is locked 6 submarginal positions and is processed with bilayer and allows pressure ring 9.
The both sides of preferred gas prevention seepage fender 5 are provided with wire lath 13, are provided with steel band 14 outside wire lath 13, and wire lath 13 and steel band 14 outside are flexible concrete spray coatings 15.
Slurries are injected gas prevention seepage fender 5 by penetrating slurry hole 8 by hollow slip casting anchor lock 6, then its one end pallet 12 support column, tighten in port with lockset 11 again, thus hollow slip casting anchor lock 6 is combined into one with gas prevention seepage fender 5 effectively, improve the object that gas prevention seepage fender 5 carries pressure itself.When gas prevention seepage fender 5 deflection is little, hollow slip casting anchor lock 6 pressures less time, suffered stress is in its tolerance range, and hollow slip casting anchor lock 6 deformation can not occur substantially.Along with the increase of 6 pressures locked by hollow slip casting anchor, bilayer allows pressure ring 9 play outstanding role, and bilayer allows pressure ring 9 can again allow pressure allowing for the first time after pressure, thus increase hollow slip casting anchor lock 6 allow pressure scope, make hollow slip casting anchor lock 6 meeting with stresses under load effect and be not easily pulled off destruction.
