Silk modes, the operating efficiency such as ties and is also improved.Resin anchor is replaced using seamed pipe anchoring-bolt, construction procedure compared with having lacked 3 steps,
Efficiency significantly improves.Seamed pipe anchoring-bolt protruded length is fixed, and anchor force squeezes into i.e. anchoring and comes into force, and quality is secure, ensures simultaneously
The safety of hot work in progress personnel.On the other hand, supporting expense reduces.
Detailed description of the invention
Fig. 1 is the schematic illustration of bolting with wire mesh method provided by the invention.
Specific embodiment
The embodiment of the present application solves mechanization bolting with wire mesh efficiency in the prior art by providing a kind of bolting with wire mesh method
It is limited by manual operation, the insecure technical problem of supporting quality.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
It states technical solution to be described in detail, it should be understood that the specific features in the embodiment of the present invention and embodiment are to the application skill
The detailed description of art scheme, rather than the restriction to technical scheme, in the absence of conflict, the embodiment of the present application
And the technical characteristic in embodiment can be combined with each other.
Referring to Fig. 1, a kind of bolting with wire mesh method, comprising:
The position that bolting with wire mesh is needed according to tunnel throws the net the abutting of piece 1 to one nation of tunnel for first, is drilled with mechanized equipment
Large arm withstands mesh sheet center, starts to drill and installs the first seamed pipe anchoring-bolt 4 placed in the middle wherein, mesh sheet and rock mass is fixed with anchor；
Spacing arrangement second is overlapped according to mesh sheet to throw the net piece 2, the described second center for throwing the net piece is then fixed with anchor, i.e.,
Using above-mentioned mechanical method, seamed pipe anchoring-bolt 5 in second is anchored；
Be overlapped compress described first throw the net piece 1 and described second throw the net piece 2 overlapping regions, then pass through net overlap joint anchor pole
3 are anchored at the corner areas of overlapping regions on rock mass, that is, anchor to form two anchorings in the corner areas of overlapping regions
Point；
It repeats the above steps, it is a gang of to top plate from tunnel, then complete bolting with wire mesh to another nation in tunnel from the top plate and apply
Work.
In the above process, using mesh sheet as the medium of label, borehole anchorage process is instructed by its morphological feature, to keep away
The complicated measurement of mechanized operation, the processes such as label, the efficiency of elevating mechanismization operation are exempted from.Anchor is ensured to a certain extent
Distance between tie rods improves construction efficiency；By anchor pole, mesh sheet and overlapped that mode forms firm overall structure；Instead of tradition
Net and net overlap joint modes, the operating efficiency such as tie with iron wire and are also improved.
On the other hand, existing frequently-used resin anchor is replaced using seamed pipe anchoring-bolt, resin anchor construction procedure is divided into: bored
Six steps such as m- laying mesh sheet-installation pallet when hole-dispensing Anchor Agent-installation anchor pole-waiting anchoring；And seamed pipe anchoring-bolt construction step
It is rapid: three steps such as lapping-drilling-installation anchor pole (band pallet).3 steps are lacked compared with six present steps, efficiency significantly improves.
Seamed pipe anchoring-bolt protruded length is fixed, and anchor force squeezes into i.e. anchoring and comes into force, and quality is secure, while ensuring and applying
The safety of worker person.On the other hand, supporting expense reduces.
In general, adjacent described first throw the net piece 1 and described second throw the net piece 2 center seamed pipe anchoring-bolt and
The layout of two anchor poles of the corner areas of overlapping regions is anchored as diamond shape layout.
It is, the first seamed pipe anchoring-bolt 4, the second seamed pipe anchoring-bolt 5 placed in the middle and described two net overlap joint anchor poles 3 placed in the middle
The diamond structure of formation rule promotes the reliability of anchoring.
Further, when executing bolting with wire mesh, the length direction of mesh sheet and the axial direction in tunnel are consistent；
Wherein, the width A of mesh sheet, length B, the anchor pole spacing a on netting width direction, the side length of element c of mesh sheet with
And mesh sheet overlapping regions lap of splice n should meet following relationship:
A=a+nc, B=2a+nc.Consequently facilitating the specification of mesh sheet, the design of spacing of anchor pole etc..
In general, the mesh sheet uses reinforced mesh.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
The bolting with wire mesh method provided in the embodiment of the present application is replaced by mesh sheet shape and is marked, improves construction efficiency,
To reduce before construction with ruler measurement palisades spacing and the step of make marks；Anchor pole spacing is ensured to a certain extent, is improved
Construction efficiency；By anchor pole, mesh sheet and overlapped that mode forms firm overall structure；Instead of traditional net and net overlap joint iron
Silk modes, the operating efficiency such as ties and is also improved.Resin anchor is replaced using seamed pipe anchoring-bolt, construction procedure compared with having lacked 3 steps,
Efficiency significantly improves.Seamed pipe anchoring-bolt protruded length is fixed, and anchor force squeezes into i.e. anchoring and comes into force, and quality is secure, ensures simultaneously
The safety of hot work in progress personnel.On the other hand, supporting expense reduces.
It should be noted last that the above specific embodiment is only used to illustrate the technical scheme of the present invention and not to limit it,
Although being described the invention in detail referring to example, those skilled in the art should understand that, it can be to the present invention
