Abstract
The utility model discloses a free type singe-aperture multi-anchor-head antiseptic prestressed tendon comprising a guide cap, single anchor heads, an injection pipe, anchor plates and a high-strengthlow-looseness unbonded steel streakline. The prestressed tendon is characterized by also comprising an isolating bracket, a pre-buried steel sleeve, a steel substrate, an anchor and a steel protective sleeve; a plurality of single anchor heads are combined with the corresponding anchor plates to form an anchor head part; the high-strength low-looseness unbonded steel streakline passes through theanchor head part, the isolating bracket and the anchor and is exposed out of the anchor; the surface of the exposed part of the high-strength low-looseness unbonded steel streakline is coated with aconcrete layer; a position at which the anchor is contacted with a reinforced concrete anchor wall is provided with the steel substrate; and the pre-buried steel sleeve is contacted with the upper endpart and the lower end part of the isolating bracket, passes through the reinforced concrete anchor wall and then is contacted with the steel substrate. The prestressed tendon realizes even stress distribution, is favorable for maintaining long-term anchoring of the tendon, strengths the anchoring effect, improves the rock-soil stability and solves a problem concerning the stability of high-slopewall rock.
Description
Technical field
The utility model relates to a kind of free style multi anchors in single hole anticorrosion type prestress anchorage cable.
Background technology
The highway section on extensive landslide often takes place in some; from the engineering geology analysis-by-synthesis; mining area engineering geological conditions complexity; the rock of making side slope is soft; weak intercalated layer is densely distributed, and it is bigger that the partial section side slope is influenced by structural fault, and artificial or machinery all is difficult to punishment; but it is bigger to engineering safety influence, particularly may fall under heavy rain or earthquake, concussion of blasting, avalanche.Therefore, these locations need the anchor cable device to carry out consolidation process.The steel strand of present tension type prestress anchorage cable anchoring section are exposed, and easily by groundwater erosion, and its anchoring section leading portion is the tensile stress concentration zones, and weak in back segment, easily produces shear failure.There is the deficiency to bad ground bad adaptability, anchoring section stress are concentrated, underground water needs reaming or growth and employing secondary grouting etc. to erosion, the anchoring section of anchor cable steel strand in the tradition prestress anchorage cable.
The utility model content
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of free style multi anchors in single hole anticorrosion type prestress anchorage cable, can effectively solve the problem that above-mentioned prior art exists.
The technical solution of the utility model is: a kind of free style multi anchors in single hole anticorrosion type prestress anchorage cable, comprise guiding cap, single anchor head, Grouting Pipe, anchor slab, high-strength underrelaxation does not have bonding steel streakline, it is characterized in that: also comprise isolating frame, the pre-buried steel sleeve pipe, billet, ground tackle and steel sheath, several single anchor heads and corresponding anchor slab are formed the anchor head part, high-strength underrelaxation does not have bonding steel streakline and passes described anchor head part, isolating frame and ground tackle are also paid ground tackle, the high-strength underrelaxation of expenditure does not have bonding steel streakline surface and scribbles layer of concrete, ground tackle and steel concrete anchor wall contact position are provided with billet, the pre-buried steel sleeve pipe contacts with the upper and lower end parts of isolating frame, and contacts with billet after passing the steel concrete anchor wall.Be provided with the bunch ring between the isolating frame, do not have bonding steel streakline in order to the high-strength underrelaxation of fixing between two isolating frames.
The beneficial effects of the utility model are: concentrate at prestress anchorage cable anchoring section stress; problems such as anchor cable corrosion; this utility model free style multi anchors in single hole anticorrosion type prestress anchorage cable anchoring section stress distribution is the Compound Distribution of tension and compression stress; improved peak stress; stress distribution is comparatively even; the stretch-draw section has adopted steel sheath and butter protection; can compensate stretching force according to actual conditions; guarantee making full use of of anchor cable; this anchor cable has better anticorrosive property; be beneficial to the long-acting anchoring that keeps anchor cable, strengthened compliance, strengthened anchoring effect bad ground; improve the stability of ground, solved high slope surrounding rock stability problem.

Fig. 1 is the schematic diagram of the utility model embodiment.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of free style multi anchors in single hole anticorrosion type prestress anchorage cable comprises that guiding cap 1, single anchor head 2, Grouting Pipe 3, anchor slab 4, high-strength underrelaxation do not have bonding steel streakline 5, isolating frame 7, pre-buried steel sleeve pipe 8, billet 10, ground tackle 11 and steel sheath 12.Can be divided into three sections according to its stress: anchoring section, rely on slurry and on every side the frictional resistance between the ground anchored force is provided.Mainly not having bonding steel streakline 5, bunch ring 6 and isolating frame 7 by guiding cap 1, several single anchor head 2, Grouting Pipe 3, several anchor slab 4, high-strength underrelaxation forms, Grouting Pipe 3 runs through whole anchor cable device, anchor cable adopts high-strength underrelaxation not have bonding steel streakline 5 boundlings composition, adopt aperture sealing perfusion, slurries inwardly pour into from Grouting Pipe 3, and water is then directly discharged.Free section plays the power transmission effect.Mainly form by isolating frame 7 and bunch ring 6, high-strength underrelaxation does not have bonding steel streakline 5 and passes several isolating frames 7, wherein is provided with bunch ring 6 between two isolating frames 7, and bunch ring 6 plays fixation, because each classification anchor slab 4 is all being born load, total anchor-hold disperses along each classification anchor, has overcome stress and has concentrated, simultaneously can be according to rocky condition, adjust classification anchor slab spacing, make the anchorage cable anchoring section in the intact rock part, thereby improved the stress of anchoring section, strengthened anchoring effect.The stretch-draw section has adopted steel sheath 12, and the butter protection can be set, for the anchorage cable stretching locking applies prestressing force.It does not mainly have bonding steel streakline 5, ground tackle 11, anchor wall 9 by high-strength underrelaxation and forms, high-strength underrelaxation does not have bonding steel streakline 5 and passes ground tackle 11 and partly pay ground tackle 11, ground tackle 11 is provided with billet 10 near the face of anchor wall 9, one side on the other side is provided with steel sheath 12, and pre-buried steel sleeve pipe 8 passes anchor wall 9 backs and contacts with billet 10.Behind the tensioning fixation, cut off the high-strength underrelaxation of paying part and do not have bonding steel streakline 5, reserve the high-strength underrelaxation of 30-60mm and do not have bonding steel streakline 5, use the concrete end socket in its outside, in case corrosion and destruction.
