Description

A kind of self-feeding anchor pile structure
Technical field
The utility model relates to anchor structure applied technical field, especially a kind of self-feeding anchor pile structure.
Background technology
Self-feeding anchor pile structure is the most basic ingredient of roadway support in the middle of contemporary colliery, and he makes country rock self supporting self by the surrounding rock consolidation in tunnel together, present anchor pole not only for mine, also in engineering, to side slope, tunnel, dam body carries out main body reinforcing.Ordinary mortar anchor pole have such as collapse hole, cannot the difficult problems such as inserted link, slip casting is not full, be difficult to the effect playing bolt support, reduce the supporting capacity of country rock, be unfavorable for the monolithic stability of country rock.Therefore, for the problems referred to above, we propose a kind of self-feeding anchor pile structure.
Prior art can not meet the needs of people, and for making up prior art deficiency, it is simple that the utility model aims to provide a kind of structure, connects closely, safe and reliable, be conducive to the self-feeding anchor pile structure that works under loose, broken environment.
For achieving the above object, the utility model by the following technical solutions: a kind of self-feeding anchor pile structure, at least comprises drill bit, anchor bar body, coupling sleeve, stop grouting plug, arch backing plate and nut; Described anchor bar body runs through and is arranged on overall upper end, and miscellaneous part all runs through and is arranged on anchor bar body; Described drill bit is arranged on overall left end, and is threaded connection with anchor bar body; Described coupling sleeve is arranged on overall middle part, and can rotate on anchor bar body; Described stop grouting plug is arranged on overall right-hand member, and is threaded connection; Described arch backing plate is arranged on the right side of stop grouting plug, and is connected with stop grouting plug spot welding; Described nut is arranged on the right side of arch backing plate.
As optimisation technique scheme of the present utility model: described stop grouting plug and arch backing plate form propeller type structure; Described anchor bar body is sleeved on coupling sleeve inside, and anchor bar body external surface is threaded with coupling sleeve inner surface.
Compared with prior art, the beneficial effects of the utility model are: described anchor bar body adopts good thick-walled seamless steel pipes material, perfection thread surface forming technology efficiently, the unification of the functions such as self-feeding anchor pile boring, slip casting, anchoring can be reached, described anchor bar body has continuous print corrugated thread, drill bit can be coordinated to complete as drilling rod and hole into anchor hole, described stop grouting plug and arch backing plate weld together.Slip casting can be made efficiently to keep stronger grouting pressure, filling space fully, fixing fragmented rock body, deep-level country rock stress equilibrium can be delivered on perisporium country rock by backing plate, the nut of high strength, reaches the object of country rock and anchor pole supporting each other, self-feeding anchor pile as drilling rod without the need to extracting, there is not hole problem of collapsing, its hollow can be used as slip casting passage, carries out slip casting from the inside to the outside, self-feeding anchor pile length can be made to creep into as required while lengthen by high strength coupling sleeve.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of self-feeding anchor pile structure, at least comprises drill bit 1, anchor bar body 2, coupling sleeve 3, stop grouting plug 4, arch backing plate 5 and nut 6; Described anchor bar body 2 runs through and is arranged on overall upper end, and miscellaneous part all runs through and is arranged on anchor bar body 2; Described drill bit 1 is arranged on overall left end, and is threaded connection with anchor bar body 2; Described coupling sleeve 3 is arranged on overall middle part, and can rotate on anchor bar body 2; Described stop grouting plug 4 is arranged on overall right-hand member, and is threaded connection; Described arch backing plate 5 is arranged on the right side of stop grouting plug 4, and is connected with stop grouting plug 4 spot welding; Described nut 6 is arranged on the right side of arch backing plate 5.
As optimisation technique scheme of the present utility model: described stop grouting plug 4 and arch backing plate 5 form propeller type structure; It is inner that described anchor bar body 2 is sleeved on coupling sleeve 3, and anchor bar body 2 external surface is threaded with coupling sleeve 3 inner surface.
As operating principle of the present utility model: when described self-feeding anchor pile structure is crept into, chassis or hand-held drifter is adopted to creep into projected depth by the anchor pole installing drill bit, anchor pole lengthens as needed, available coupling sleeve connects, then crept into by rig, unload rig, stop grouting plug is installed, be arranged on anchor hole inner orifice place, special circumstances slurry pressure is comparatively large or country rock is too broken, also Anchor Agent sealing of hole can be used, by quick filling adaptor, end of anchor rod is connected with grouting pump, to machine slip casting, shut down when slip casting is full and pressure reaches design load, grouting pressure is determined according to design parameters and slurry filling machine performance, according to design needs, backing plate and nut are installed, when constructing under all kinds of wall rock condition, do not need sleeve pipe retaining wall, the special skills such as pre-pouring grout also can form anchor hole and ensure anchoring and slip casting effect.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
