Description
Technical field
The invention belongs to Geotechnical Engineering Prevention Technique field, it is related to a kind of embedded anchor of prestress anchorage cable, also relates to
And using the pull-type retaining structure anchoring process of anchor of said apparatus.
Background technology
Prestress anchorage cable with concrete stake, post, plate soil-baffling structure constitute the pull-type retaining structure of anchor in high slope control, deep basal pit
There is relatively broad application in the Geotechnical Engineering prevention and control field such as supporting.Power transmission method is generally beam between traditional anchor cable and soil-baffling structure
Formula power transmission method, i.e., between stake or intercolumniation set steel wale or concrete breast beam, the anchor force of anchor cable is passed to by waist rail
Soil-baffling structure, so that it is guaranteed that retaining structure and stability of slope, reach Geotechnical Engineering and prevent and treat purpose.
The problem that traditional pull-type retaining structure of anchor is present：
The 1st, waist rail is set on retaining structure, steel wale is especially set, due to soil-baffling structure construction deviation, its center line
Not in approximately the same plane, so as to after waist rail erection, it is impossible to effectively contacted with part soil-baffling structure, cause anchor cable, waist rail to be received
Power uneven generation partly or wholly property destruction.
2nd, peripheral hardware waist rail on retaining structure, need to take certain construction operation width, and conventional steel wale about 400mm is mixed
Solidifying soil waist rail is then bigger, and thereby resulting in earth excavation and backfill amount increases.
3rd, external beam or existing other kinds of anchor structure are not fixed easily, and construction deviation is big, and input manpower and materials
It is many, there is falling risk during construction and use.
4th, the anchor force of anchor cable is passed to retaining structure and increased Path of Force Transfer by beam type power transmission method requirement waist rail, and power transmission is not
Directly.
The 5th, waist rail is set on retaining structure, steel wale is especially set, long-term exposed, easy-to-rust causes stress loss
It is larger.Exposed waist rail is often scratched by earth excavation, structure construction collision and falling object impact etc. unfavorable factor influenceed.
6th, in foundation ditch, the slope project in sideline (such as arc, shaped form sideline) in irregular shape, external waist rail should
With being restricted, or even it is difficult with.
The content of the invention
It is an object of the invention to provide a kind of embedded anchor of prestress anchorage cable, the device can be by anchor cable and earth-retaining
Structure is directly connected to.
It is another object of the present invention to provide the pull-type retaining structure anchoring process of anchor using said apparatus, the method
Easy construction, without anchor structure falling risk.
The technical solution adopted in the present invention is, a kind of embedded anchor of prestress anchorage cable, including reinforcing structure, plus
Strength structure is connected with soil-baffling structure, and anchor chair is provided with reinforcing structure, and steel strand wires hole is provided with anchor chair.
The features of the present invention is also resided in,
Reinforcing structure is annular stiffener, square stiffener, closing irregular shape stiffener, arc stiffener, straight line
Shape put more energy into version, flute profile put more energy into version, do not close irregular shape stiffener or reinforcing bar.
Soil-baffling structure is support pile, the cage bar of reinforcing structure and support pile, the spiral bar of support pile or muscle of putting more energy into welding.
Anchor chair sets several, at least provided with an anchor chair on same plane.
Steel strand wires hole sets several, and the center of circle in several steel strand wires holes is located along the same line.
Steel strand wires hole sets several, and several steel strand wires holes are divided into the center of circle positioned at 2 groups on different straight lines.
Another technical scheme of the present invention is, the anchoring process of the pull-type retaining structure of anchor, using a kind of prestressing force
The embedded anchor of anchor cable, specifically implements according to following steps：
Step 1, makes soil-baffling structure framework of steel reinforcement, and the embedded anchor of prestress anchorage cable is fixed on into soil-baffling structure steel
On muscles and bones frame；
Step 2, hangs soil-baffling structure framework of steel reinforcement in the soil-baffling structure hole for pre-setting, and is poured to soil-baffling structure framework of steel reinforcement
Concrete is built, so as to form soil-baffling structure, soil-baffling structure sets several；
Step 3, after soil-baffling structure concrete setting, chisels concrete cover at anchor chair and discloses in anchor cable elevation location
Go out steel strand wires hole；
Step 4, steel strand wires hole is passed through by the free end of the steel strand wires of anchor cable, uses anchorage tensioning fixation.
The features of the present invention is also resided in,
Two anchor cables, two free ends of the steel strand wires of anchor cable point are set between two neighboring soil-baffling structure on same absolute altitude
Steel strand wires hole that Chuan Guo be on two soil-baffling structures, uses anchorage tensioning fixation.
One anchor cable, the steel of the anchor cable between two soil-baffling structures are set between two neighboring soil-baffling structure on same absolute altitude
Twisted wire is divided into two beams, and the free end of two beam steel strand wires is each passed through the steel strand wires hole on two soil-baffling structures, uses anchorage tensioning lock
It is fixed.The free end of the steel strand wires of the anchor cable on the outside of first and last soil-baffling structure passes through steel strand wires hole, uses anchorage tensioning
Locking.
The beneficial effects of the invention are as follows：
1st, directly by anchorage cable anchoring on soil-baffling structure, the pull-type retaining structure of anchor is formed, not by soil-baffling structure construction deviation
Influence, strong adaptability, anchor cable and soil-baffling structure uniform force, structural stability are preferable.
2nd, the embedded anchor is arranged in soil-baffling structure, between the protection of linked network spray plane is arranged at soil-baffling structure, completely
It is not take up exceptional space；For base pit engineering, can reduce and distance is put outside excavation of foundation pit line, and then reduce the excavation of the earthwork, return
The amount of filling out, better economy.
3rd, directly by anchorage cable anchoring on soil-baffling structure, anchor cable is directly connected to soil-baffling structure, and Path of Force Transfer is simple, structure
Reliability it is preferable.
4th, it is arranged in soil-baffling structure, it is simple, light and handy, after after anchorage cable stretching locking, it is easier to closing, good corrosion resistance, drop
It is low such as to be scratched by external world's construction, impact and influence.
5 and soil-baffling structure be one overall, do not controlled by foundation ditch, slope anchorage sideline shape, be applicable to unilateral anchoring bar
Part.
6th, the concrete anti-pressure ability of anchor present position near zone soil-baffling structure is effectively improved.
7th, prestressed cable anchorage device is fixed on framework of steel reinforcement in soil-baffling structure Making of reinforcement cage, with reinforcing bar
Frame is produced on same workbench, is constructed simultaneously with framework of steel reinforcement, without anchor structure falling risk, easy construction.
8th, before anchorage cable stretching locking, corresponding position concrete cover is disclosed, can be with anchor cable pore-forming, slip casting etc. simultaneously
Construction, the excavation construction time is not taken individually.
9th, without the waist rail fabrication and installation operation of the pull-type retaining structure beam type power transmission method of anchor, the duration is saved.
10th, suitable for the retaining structure mode of a traditional anchor, it is also applied for a retaining structure mode for two anchors.
