Description
Technical field
The utility model is related to grouting equipment field, specifically a kind of colliery breaking surrounding rock deep hole grouting bracing means.
Background technology
Country rock (wall rock) geology noun, is referred to around tunnel in certain limit, the stabilization to barrel has an impact
Rock (soil) body, relative to the rock around certain crust materials.It common are the country rock of magma and the country rock of ore body.In rock
In underground engineering, the surrounding rock body of stress state change occurs due to being influenceed by excavation.Around around ore body and rock mass
Rock claims country rock.But, the former is the country rock of ore body, and the latter is the country rock of rock mass.In general, ore body and country rock
Border is analyzed by systematic sampling, is drawn a circle to approve according to certain industrial index.
Colliery rock crusher needs slip casting to be reinforced, and existing bracing means is easily pressurized collapse, and causing can not slip casting
Situation.
Utility model content
The purpose of this utility model is to provide a kind of colliery breaking surrounding rock deep hole grouting bracing means, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of colliery breaking surrounding rock deep hole grouting bracing means, including rebar cylinder mould, intrusion pipe, outer tube, upper end cover and
Drill bit, the intrusion pipe is socketed on the outside of rebar cylinder mould, and intrusion pipe is fixedly connected with rebar cylinder mould by weldment；It is described to fill
Outer tube is socketed with the outside of note pipe, the top of the outer tube and intrusion pipe is bolted on upper end cover, and upper end cover
Provided with connector, upper end cover connects rig and slip casting machine using connector；The drill bit is fixed at the bottom of rebar cylinder mould；
The drill bit lower end is cutting-edge structure, and the outer wall of drill bit is provided with screw thread；The outer wall of the outer tube is provided with grout outlet, leads to
Crossing intrusion pipe causes slip casting to be sprayed from grout outlet, and now intrusion pipe not only acts as supporting role, it is to avoid collapsed between outer tube
The situation of contracting.
It is used as further program of the utility model：The intrusion pipe is made of steel, not only cheap, and tool
There is higher intensity.
It is used as the utility model further scheme：The weldment is bayonet unit.
Compared with prior art, the beneficial effects of the utility model are：The outer wall of outer tube is provided with the utility model
Grout outlet, by intrusion pipe so that slip casting from grout outlet spray, now intrusion pipe not only acts as supporting role, it is to avoid outer tube it
Between there is the situation of collapse.

Intrusion pipe 2 is fixedly connected with rebar cylinder mould 1 by weldment 6；The outside of intrusion pipe 2 is socketed with outer tube 3, the outer tube 3
Upper end cover 4 is connected by bolt 7 with the top of intrusion pipe 2, and upper end cover 4 is provided with connector 5, upper end cover 4 utilizes connection
First 5 connection rig and slip casting machine；The drill bit 8 is fixed at the bottom of rebar cylinder mould 1；Tied for tip the lower end of drill bit 8
Structure, and the outer wall of drill bit 8 is provided with screw thread 9；The outer wall of the outer tube 3 is provided with grout outlet, causes slip casting by intrusion pipe 2
Sprayed from grout outlet 10, now intrusion pipe 2 not only acts as supporting role, it is to avoid occur the situation of collapse between outer tube.
The intrusion pipe 2 is made of steel, not only cheap, and with higher intensity.
The weldment 6 is bayonet unit.
Operation principle of the present utility model is：The outer wall of outer tube 3 is provided with grout outlet, causes slip casting by intrusion pipe 2
Sprayed from grout outlet, now intrusion pipe 2 not only acts as supporting role, it is to avoid occur the situation of collapse between outer tube.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
