Description
Technical field
The invention belongs to geotechnical engineering Prevention Technique field, relate to the embedded anchor device of a kind of prestress anchorage cable, also relate to the pull-type retaining structure anchoring process of anchor adopting said apparatus.
Background technology
Prestress anchorage cable has in the geotechnical engineering such as high slope control, deep foundation pit support prevention and control field with the pull-type retaining structure of anchor that concrete stake, post, plate soil-baffling structure form to be applied comparatively widely.Between traditional anchor cable and soil-baffling structure, power transmission method mostly is beam type power transmission method, namely between stake or intercolumniation steel wale or concrete breast beam are set, by waist rail, the anchored force of anchor cable is passed to soil-baffling structure, thus guarantee retaining structure and stability of slope, reach geotechnical engineering and prevent and treat object.
The pull-type retaining structure Problems existing of tradition anchor:
1, retaining structure arranges waist rail, especially steel wale is set, due to soil-baffling structure construction deviation, its center line is not in same plane, thus after waist rail erection, effectively can not contact with part soil-baffling structure, cause anchor cable, waist rail discontinuity that local or globality destruction occur.
2, peripheral hardware waist rail on retaining structure, need take certain construction operation width, conventional steel wale is about 400mm, and concrete breast beam is then larger, causes soil excavation and backfill amount to increase thus.
3, the anchor structure of external beam or existing other types is not easily fixed, and construction deviation is large, and input manpower and materials are many, has falling risk in construction and use procedure.
4, beam type power transmission method requires that the anchored force of anchor cable is passed to retaining structure and adds Path of Force Transfer by waist rail, and power transmission is not direct.
5, retaining structure arranges waist rail, especially arrange steel wale, exposed for a long time, easy-to-rust, causes stress loss larger.Exposed waist rail often scratches by soil excavation, the impact of structure construction collision and the unfavorable factor such as falling object impact.
6, in the foundation ditch, slope project in sideline out-of-shape (as arc, shaped form sideline), the application of external waist rail is restricted, and is even difficult to use.
Summary of the invention
The object of the present invention is to provide the embedded anchor device of a kind of prestress anchorage cable, anchor cable can directly be connected with soil-baffling structure by this device.
Another object of the present invention is to provide the pull-type retaining structure anchoring process of anchor adopting said apparatus, the method easy construction, without anchor structure falling risk.
The technical solution adopted in the present invention is, the embedded anchor device of a kind of prestress anchorage cable, and comprise reinforcing structure, reinforcing structure is connected with soil-baffling structure, and reinforcing structure is provided with anchor chair, anchor chair is provided with steel strand hole.
Feature of the present invention is also,
Reinforcing structure is annular stiffener, square stiffener, close irregularly shaped stiffener, arc stiffener, linear put more energy into version, flute profile puts more energy into version, do not close irregularly shaped stiffener or reinforcing bar.
Soil-baffling structure is soldier pile, and reinforcing structure welds with the main muscle of soldier pile, the spiral bar of soldier pile or muscle of putting more energy into.
Anchor chair arranges several, same plane is at least arranged an anchor chair.
Steel strand hole arranges several, and the center of circle in several steel strand holes is located along the same line.
Steel strand hole arranges several, and several steel strand holes are divided into the center of circle and are positioned on different straight line 2 groups.
Another technical scheme of the present invention is, the anchoring process of the pull-type retaining structure of anchor adopts the embedded anchor device of a kind of prestress anchorage cable, specifically implements according to following steps:
Step 1, makes soil-baffling structure cage of reinforcement, is fixed on soil-baffling structure cage of reinforcement by embedded for prestress anchorage cable anchor device;
Step 2, hangs soil-baffling structure cage of reinforcement in the soil-baffling structure hole pre-set, and to soil-baffling structure cage of reinforcement concreting, thus form soil-baffling structure, soil-baffling structure arranges several;
Step 3, after soil-baffling structure concrete setting, chisels anchor chair place concrete cover at anchor cable elevation location and exposes steel strand hole;
Step 4, by the free end of the steel strand of anchor cable through steel strand hole, uses ground tackle tensioning fixation.
Feature of the present invention is also,
Between adjacent two soil-baffling structures, same absolute altitude arranges two anchor cables, the free end of the steel strand of two anchor cables is each passed through the steel strand hole on two soil-baffling structures, uses ground tackle tensioning fixation.
Between adjacent two soil-baffling structures, same absolute altitude arranges an anchor cable, the steel strand of the anchor cable between two soil-baffling structures are divided into two bundles, and the free end of two bundle steel strand is each passed through the steel strand hole on two soil-baffling structures, uses ground tackle tensioning fixation.The free end of the steel strand of the anchor cable outside first and last soil-baffling structure, through steel strand hole, uses ground tackle tensioning fixation.
The invention has the beneficial effects as follows:
1, directly by anchorage cable anchoring on soil-baffling structure, form the pull-type retaining structure of anchor, do not affect by soil-baffling structure construction deviation, strong adaptability, anchor cable and soil-baffling structure uniform force, structural stability is better.
2, this embedded anchor device is arranged in soil-baffling structure, and the protection of linked network spray plane is arranged between soil-baffling structure, the not occupying volume external space completely; For base pit engineering, can reduce to put distance outside excavation of foundation pit line, and then reduce excavation, the backfill amount of the earthwork, better economy.
3, directly by anchorage cable anchoring on soil-baffling structure, anchor cable is directly connected with soil-baffling structure, and simply, reliability of structure is better for Path of Force Transfer.
4, be arranged in soil-baffling structure, simple, light and handy, after anchorage cable stretching locking, more easily close, good corrosion resistance, reduction is subject to extraneous construction as scratched, impact etc. affects.
5, be an entirety with soil-baffling structure, not by foundation ditch, slope anchorage sideline shape controlling, be applicable to monolateral anchoring condition.
6, the concrete anti-pressure ability of anchor device present position near zone soil-baffling structure is effectively improved.
7, prestressed cable anchorage device is fixed on cage of reinforcement when soil-baffling structure Making of reinforcement cage, with Making of reinforcement cage on same working platform, constructs with cage of reinforcement, without anchor structure falling risk, easy construction simultaneously.
8, before anchorage cable stretching locking, corresponding position concrete cover is disclosed, can construct with anchor cable pore-forming, slip casting etc. simultaneously, not take separately the excavation construction time.
9, there is no the waist rail fabrication and installation operation of anchor pull-type retaining structure beam type power transmission method, save the duration.
10, be applicable to the retaining structure mode of a traditional anchor, be also applicable to the retaining structure mode of two anchors.
