Description

A kind of multiple-anticorrosion anchor rod increasing anchored force
Technical field
The utility model relates to a kind of anchor pole, particularly relates to a kind of multiple-anticorrosion anchor rod increasing anchored force.
Background technology
In mine working, chamber and constructing tunnel that geotechnical engineering relates to, jeopardize safety for preventing surrouding rock deformation or unstability, the main support technology of one reinforced country rock adopts bolt support.Bolt support is on roadway surrounding rock, bore anchor hole, by anchor rod anchored in anchor hole.
Rockbolt installation in country rock after, As time goes on, easily some electrolyte solutions are infiltrated in anchor hole, strong alkaline water contained in the weak cementing soft rock rock stratum of such as argillization, seawater etc. contained in seabed tunnel, can there is galvanic interaction in electrolyte solution and anchor pole, produce corrosiveness, and then affect life-span and the supporting effect of anchor pole to anchor pole.Therefore, anchor pole Anticorrosion Problems is in the earth formation very important.
Along with in world wide to the increase of energy demand, mining rate constantly increases, and superficial part resource is reduced gradually, so turn to deep mining to be trend of the times.But circumstance complication residing for deep rock mass, usually along with high-ground stress, High-geotemperature, hyperosmosis and strong exploitation disturbance, and roadway deformation amount is large, deformation time long, rock crusher is serious, and anchor pole is easier to lose efficacy, and roadway maintenance is very difficult.Although tradition end-fixed bolter adhesion strength is high, quick solidifying, security reliability are high, but just carry out end anchorage with resin explosive roll, full length fastening cannot be realized, it is concentrated and disrumpent feelings that anchor pole just easily produces stress under heavily stressed large deformation condition, have a strong impact on the control effects of bolt support to country rock, particularly cannot solve a supporting difficult problem for deep weak broken, dynamic pressure, roadway with large deformation.Therefore, how while solution anchor pole Anticorrosion, its anchoring effect can be increased again, just to seem especially important.
Utility model content
The purpose of this utility model is, provides a kind of anchor pole, and this anchor pole effectively can solve that anchor pole under complex stratum condition is perishable, the hypodynamic difficult problem of anchoring, and then can increase its anchoring effect and application life.
The structure increasing the multiple-anticorrosion anchor rod of anchored force of the present utility model is, comprises the stifled slurry plug of anchor bar body, anchor head, sleeve pipe, anchor hole stop grouting plug, pallet, nut and anchor pole.
Described anchor bar body inside is provided with slip casting passage and exhaust passage, two pairs of symmetrical anchor bar body grout outlets are provided with in anchor bar body slip casting passage inner end, and described anchor bar body tail end is provided with grouting port, described anchor bar body grout outlet and grouting port all communicate with slip casting passage, described anchor head is provided with air vent, and described air vent communicates with exhaust passage.
Described sleeve pipe is steel, itself and anchor bar body are threaded connection, and 1/7 section, sleeve pipe upper and lower inner chamber is steel tubular structure, main part inner chamber is semiclosed female thread structure, described bushing outer surface is provided with coarse-pitch thread and zinc ring, and is provided with six sleeve pipe extravasating hole at described cannula tip hoop.
Construction sequence of the present utility model is as follows:
After accomplishing fluently anchor hole, anchor bar body with anchor head and sleeve pipe is inserted in anchor hole, then anchor hole stop grouting plug is installed, pallet and nut, then Grouting Pipe is connected at anchor bar body tail end grouting port, mortar is injected by anchor bar body afterbody to slip casting passage with grouting pump, mortar flow into cannula cavity at slip casting passage by four anchor bar body grout outlets, fill after cannula cavity until mortar, overflow in the outer anchor hole of slurry mouth inflow sleeve pipe by six sleeve pipes again, in period anchor hole and cover inner air tube discharged by anchor bar body exhaust passage by air vent, after slip casting, anchor pole stifled slurry plug is filled in grouting port, use accelerated cement sealing of hole, last fastening nut, complete installation.
Advantage of the present utility model is:
(1) anchor bar body cover has sleeve pipe, bushing outer surface is provided with the chemical property zinc ring more active than iron and steel, the effect of zinc ring is protected anchor pole by galvanic principles, mortar has been filled again in the inner chamber and the outer anchor hole of sleeve pipe of sleeve pipe, which forms the multiple-protection of mortar-sleeve pipe-zinc ring-mortar, effectively can solve an anticorrosion difficult problem for anchor pole;
(2) anchor bar body is threaded by semiclosed with sleeve pipe, and be provided with coarse-pitch thread and zinc ring outside sleeve pipe, after in the outer anchor hole of the cannula cavity such as this just makes and sleeve pipe, mortar solidifies, together with anchor pole can more effectively condense in country rock, add the anchoring pulling capacity of anchor pole, make anchoring effect more remarkable;
(3) this utility model principle is simple, working procedure system, convenience, physical and mechanical property is stablized, turn increase anchor rod anchored pulling capacity at anchor pole corrosion-resistant simultaneously and do not affect the working procedure of anchor pole, making anchor pole can be able to relieved safe handling under the complex stratum conditions such as the weak cementing soft rock rock stratum of argillization, seabed tunnel, deep tunnel.
