Description
Technical field
It the utility model is related to geotechnical anchor engineering field, and in particular to a kind of prestress wire anchor pole tensioning auxiliary dress
Put.
Background technology
At present, the application of prestressed anchor is more and more extensive, is widely used in pattern foundation pit supporting structure, slope treatment, basement and resists
It is floating to wait in engineering practice.Prestressed anchor is typically made up of (referring to accompanying drawing 8) anchor head, free segment and anchoring section.Anchor head is by exposed
Steel strand wires (steel strand wires beyond side slope beam are reserved in accompanying drawing 8) and anchorage composition are anchor poles so as to provide tensile load and
The part of locking；Anchoring section is the anchor rod anchored part in rock-soil layer, is the foundation that anchor pole provides drag；Free segment is connection
Anchor head and anchoring section and the part that can freely extend.
Anchor rod body material generally selects prestress wire, and it has intensity height, the good, easy transportation and installation of performance etc. excellent
Point, its tensile strength design load is 4 times of common hot-rolled reinforced bar or so, is the best rod body material of cost performance.Prestress steel twist
Line anchor pole tensioning fixation operability, apply prestressed stability in terms of be superior to reinforcing bar, be using at most, most have hair
The anchor pole type of exhibition prospect.
The anchoring body of prestressed anchor carries out tensioning after reaching some strength so that anchor pole from passive stress be changed into actively by
Power, apply pressure to Rock And Soil to reach the purpose of reduction displacement.
During anchor pole tensioning, exposed steel strand wires are first passed through into finished product lockset, are then passed through punching jack, and by its end with auxiliary
Help anchorage to pin, jack auxiliary anchorage using jack, realize steel strand tension process.After the completion of tensioning, jack bottom is utilized
The finished product lockset in portion pins exposed steel strand wires, then sheds load added by jack, pulling force passes through finished product lockset suffered by steel strand wires
Rock And Soil is applied in the form of pressure, completes locking work.
Above tensioning, locking process need exposed steel strand wires long enough (being typically no less than 100cm), and this not only causes steel
The waste of twisted wire, and subsequent construction (such as earth excavation, outer wall of basement waterproof, heat retaining operation etc.) is made troubles, such as
Unnecessary exposed steel strand wires are amputated immediately after fruit locking, when pre-applied force loses, can not carry out reinforcement tensioning.In some situations
Under, before tensioning, exposed steel strand wires are destroyed anchor pole, and steel strand wires end becomes loose condition (of surface), it is difficult to through anchorage, if will
