Description
Technical field
The invention belongs to bolt support technology fields, more particularly to a kind of fusing type dismountable anchor cable supporting construction.
Background technique
Anchor Cable Technique is to introduce a kind of country rock reinforcing means in China the 1960s, since the anchor cable body of rod uses
The steel strand wires of flexible have many advantages, such as that easy for installation, anchorage depth is big, bearing capacity is high and actively reinforce country rock,
Anchor cable is in China's coal-mine back supporting using very extensive.Large span intersection, fault belt etc. intricately
In soft rock roadway support under the conditions of matter, anchor cable has played irreplaceable role.With petering out for superficial part resource, mine
Exploitation constantly develops to deep, leads to the problem of a large amount of Deep Soft Rock therewith.1996-1997, China have introduced suspension roof support
Technology, and for China Mine Geological and working condition carried out deeper into exploitation.It lengthens, overall length resin anchoring high intensity spiral shell
Line steel anchor rod, the technologies such as small-bore resin anchoring prestress anchorage cable are gained universal acceptance and are widely applied, and become China
The leading support technology of coal mine roadway, but since km Deep Soft Rock crush roadway supporting difficulty gradually increases, supporting intensity is not
The generation of the accidents such as foot causes to crush, absciss layer, roof fall, hollow grouting cable anchor support technology are widely used.
Anchor cable can be divided into resin end anchorage, slip casting full length fastening and resin grouting joint by anchorage length and anchor three kinds
Mode.End anchorage anchor cable simple, quick construction with its installation procedure, is widely used in China's coal-mine underworkings supporting.
But using the soft-rock tunnel of end anchor supporting, when being influenced by strong dynamic pressure and significant tectonic stress, roadway deformation amount is big, anchor cable bar
Body is broken, fails to happen occasionally so that causing the unexpected unstability in tunnel.Traditional slip casting anchoring anchor cable exist installation bore diameter it is big,
The disadvantages of cement mortar setting time is long, anchoring effect is not very ideal, and is normally only used for the soft-rock tunnels such as large-section underground
The reinforcing of engineering.Resin grouting joint anchoring has both the advantages of resin end anchorage anchor cable and slip casting anchoring anchor cable, in state
Interior application is universal not enough.
The underworkings supporting of some developed country's early stages mainly applies building stones to build the branch such as arch, timber, whitewashing, metallic support
Outside handguard section, in recent years always with anchor pole（Rope）Based on supporting.Generally, for the highly stable country rock one in I grade of tunnel
As not supporting；Monomer anchor pole or anchor pole+net is generally used to carry out simple supporting on II grade of degree of stability country rock；For in III grade
Etc. the support pattern in degrees of stability country rock tunnel generally use anchor pole+" W " shape steel band+net；For IV grade of unstable surrounding rock tunnel
Generally use anchor pole+" W " shape steel band+supportings means such as net+anchor cable and slip casting；The country rock lane of deformation failure extremely easy for V
Road generally uses support pattern with stronger dynamics, such as uses truss+bolt-grouting support and anchor net beam rope spray+" U " steel combined supporting skill
Art.
Britain is in the country of 1870s first application suspension roof support open coal mine shale side slope, away from the present
There is more than 130 years history, opens the precedent of mooring rod technique application.To 1912, German Xie Liezi mine used at first
Bolt support technology is applied to the supporting of underworkings, has started the beginning of anchor pole underground engineer application.1924, the Soviet Union
Bath mine of pausing begins to use anchor pole+whitewashing to carry out supporting.Up to the present Germany is in invention " u "-shaped steel bracket in 1932
" u "-shaped steel bracket uses earliest, technical country the most mature." u "-shaped steel bracket and collapsible timbering develop fast since then
Speed, bracket material are also greatly improved, it may be said that very universal in underworkings supporting.
China's bolt support technology is started late, and mooring rod technique is tried out since the 50's of last century.It was just opened in 1956
The research and its application of beginning bolt support technology, the bolt support technology for just starting to introduce foreign countries carry out experimentally in seldom mining area
Research.In the 60's, China starts to promote the use of bolt support technology in the more stable rock stratum tunnel of wall rock condition, and starts
Using U-typed steel collapsible timbering, up to the present the totally-enclosed Yieldable steel support of U-typed is often designed to country rock grade
For in V grade of unstable surrounding rock tunnel and VI grade of extremely unstable country rock tunnel.The subsequent anchor pole seventies makes in stabilizing surrounding rock tunnel
It increased significantly with quantity, the initial stage nineties later period eighties starts to promote the use of in heading.Compared to more some main productions
For coal state, China's anchor pole has reached 80% in Rock Workings Support rate, and it is only 40% that coal road utilization rate is relatively low, and there are also very long
Stretch to walk.
Summary of the invention
