Embodiment 1
The construction method of the present invention is carried out in the steps below：
A, excavation of foundation pit and pore-forming
Pit earthwork is excavated to anchor cable construction operating surface, is crept into using rig in the soil body into anchor hole, hole depth and is more than anchor cable
0.3 ~ 0.5m of design length, the angle of anchor cable pore-forming are determined according to clay distribution, environmental requirement and equipment situation, typically
15 ~ 35 ° are taken, anchoring section is arranged in cohesive soil, silty soil or sandy soil stratum, a diameter of 150mm of anchor hole.
B, anchor cable is installed
Pore-forming is placed by double end anchor 1 and at least one or more than one single head after finishing acceptance(check) in anchor hole
Anchor 2 forms multistage adjustable detachable prestress anchorage cable to projected depth position, the guiding cap 19 of double end anchor 1
500mm is withdrawn after touching anchor hole bottom, guiding cap 19 is left certain space with anchor hole bottom, anchor is being put to anchor hole
During such as drag penalty when must be drawn off, to anchor hole dredge placement and the peace for carrying out anchor cable after processing again
Dress.This anchor set has three-level spacing：Spacing one-level is base 14, controls the stroke in the chamber 21 of base 14 of steel strand wires 3
Length is simultaneously fixed by jump ring 16；Two level is spacing to move back anchor mandrel 13 in connection sleeve pipe 12 and connection sleeve pipe 12；Three-level is spacing
For middle stay tube 8, by steel strand wires 3 and one-level bearing plate 4 formed good fixation with it is spacing.
C, slip casting conserves
Anchor set carries out slip casting after installing, Grouting Pipe passes through anchor plate 6, Yi Jiyi by the conical pipe 61 of outer anchorage 62
Level bearing plate 4 and slip casting on two level bearing plate 5 or twisted wire hole 41 penetrate anchor hole and colligation is firm, the cement mortar that will be prepared
Anchor hole is injected by Grouting Pipe, slip casting is since bottom hole, untill slurries are overflowed in aperture.The ratio of mud of neat slurry takes 0.45 ~
0.5, during according to cement mortar, cement-sand ratio 1:0.5~1:1, mix and stir and select medium coarse sand with sand, in cement mortar or cement mortar
The additive for improving grouting soil early strength or microdilatancy can be mixed, its incorporation is determined by field test.Slip casting pipe end
Portion to the distance of bottom hole is not more than 200mm, when declining in slip casting rear slurry face, carries out aperture and mends slurry, using secondary pressure slip casting
When, Grouting Pipe sets injected hole in the range of l/4 ~ l/3 of anchorage end, and pitch of holes takes 500 ~ 800mm, each slip casting interface
Injected hole takes two, and secondary grouting is the cement paste of the ratio of mud 0.5 ~ 0.55, is carried out after cement initial set, before final set, slip casting
Pressure is not less than 1.5MPa, and the maintenance of slurry is carried out after slip casting.
D, tensioning fixation
After injecting cement paste intensity reaches design load, first by the pretension tensioning of single steel strand 3, then remaining steel strand wires 3 is carried out
Integral tension, the load of tensioning are pressed 10%, 50%, 75%, 100%, 110% or 120% carry out grading tension incremented by successively, are stretched to
1.1 ~ 1.2 anchor cable stretching resistance characteristic values（Tak）When, lotus 10min is held to sandy soil layer, lotus 15min is held to cohesive soil, is then unloaded
Tensile load to design requirement locks, and loading speed is not more than 0.1NK/min.
E, steel strand wires are reclaimed
Anchor cable after the completion of branch protective function, promote the revealed section of steel strand wires 3, by steel strand wires 3 along anchor hole direction toward hole in push 15 ~
20mm distances, make to move back the chamber 21 that the front end of anchor mandrel 13 enters base 14, and neck 31 is pinned by jump ring 16, the compression of spring 17 makes
The anchor cable intermediate plate 15 for moving back the rear end of anchor mandrel 13 exits conical sleeve 18, loses the snap-lock to steel strand wires 3, and steel strand wires 3 unlock
Success, then pull out steel strand wires 3 and complete recovery.
Simply the present invention will be further described above, and is not used to limit patent of the present invention, all for the equivalent reality of the present invention
Apply, be intended to be limited solely by within the right of patent of the present invention.
