Abstract
A kind of interim anchorage of combined type, the anchorage includes pile foundation, anchor cable, anchor pole, anchorage concrete, counterweight, cable；Anchorage concrete is arranged on the top of pile foundation, and counterweight is arranged on the top of anchorage concrete；Anchor pole is arranged on the side of anchorage concrete, and cable is arranged on the opposite side of anchorage concrete；Cable is arranged along the length of anchor cable.The interim anchorage of combined type is in the pulling force come by cable transmission, transmitted first along cable to the anchor pole being attached thereto, effectively decompose the pulling force of cable transmission, again slipping property is done by what the stronger shearing resistance of pile foundation can be effectively ensured Anchor Foundation, ensure Anchor Foundation not along basal plane slip, the extraction-resistant behavior and anti-overturning of anchorage with larger withdrawal resistance, can be effectively ensured in the counterweight of anchorage top of concrete and the anchor pole of cable offside.
Description
Technical field
The present invention relates to a kind of interim anchorage structures, specifically a kind of collection pile foundation, anchor pole, with overweighting integral answer
Box-like interim anchorage.
Background technology
Anchorage is the structure of a kind of stabilization, is typically carried by the cable being attached thereto to other structures and encircles stabilization
Pulling force effect, to ensure the steady in a long-term of other structures, the effect of anchorage is particularly significant, and the stability of anchorage mainly needs to consider
The anti-slipping property of anchorage structures, do toppling property and resistance to plucking.The structure type of conventional anchorage has gravity anchor, tunnel type anchor
Fixed, rock anchor cable anchorage, pile foundation support table anchor.
There is more strict code requirement for the anchorage as permanent works, be typically designed rigorous, construction requirement is tight
Lattice, such as in recent years obtain tremendous development Analysis of Suspension Bridges ' Anchorage, constantly broken through with the span of suspension bridge, the structure of its anchorage and
Scale is also continued to increase therewith, and to the interim anchorage for temporary project, because its use time is short, part anchorage is being used
After also need to remove, this is accomplished by being that anchorage optimizes design to facing.
With the continuous breakthrough of Bridges in Our Country technology, corresponding working measure also makes rapid progress, associated jury anchor
The structure and scale of heavy stone used as an anchor also refresh constantly.
The content of the invention
The present invention be directed to a kind of collection pile foundation of interim anchorage design, anchor pole, with overweighting integral combined type jury anchor
Heavy stone used as an anchor.
Above-mentioned purpose is realized, the present invention uses following technical scheme：A kind of interim anchorage of combined type, the anchorage includes pile foundation
Plinth 1, anchor cable 2, anchor pole 3, anchorage concrete 4, counterweight 5, cable 6；
Anchorage concrete 4 is arranged on the top of pile foundation 1, and counterweight 5 is arranged on the top of anchorage concrete 4；Anchor pole 3 is set
In the side of anchorage concrete 4, cable 6 is arranged on the opposite side of anchorage concrete 4；Anchor cable 2 is diagonally disposed in anchorage concrete 4
It is interior, and stretch into counterweight 5；Length of the cable 6 along anchor cable 2 is arranged.
The angular range of anchor cable 2 and horizontal direction is 10 ° -60 °.
This interim anchorage of combined type, based on concrete anchorage, using along the cable that is connected with anchorage along long line side
To cable, anchor pole is set, directly the pulling force of cable is transmitted to ground, to reduce the stress of anchorage；On the downside of anchorage concrete
Pile foundation is set, the resistant slide power of anchorage is increased with the stronger shear behavior of pile foundation；Set in the anchorage side of cable offside
Anchor pole, to strengthen the anti-overturning and extraction-resistant behavior of anchorage；Increase counterweight in anchorage top of concrete, anchorage can be increased comprehensively
Anti-slipping property, do toppling property and resistance to plucking, while again be beneficial to interim anchorage dismounting.
Brief description of the drawings
Fig. 1 is elevational schematic view of the present invention.
Fig. 2 is floor map of the present invention.
In figure：1st, pile foundation, 2, anchor cable, 3, anchor pole, 4, anchorage concrete, 5, counterweight, 6, cable.
Embodiment
As shown in Figure 1-2, the interim anchorage of combined type is in the pulling force come by cable transmission, first along cable to therewith
Connected anchor pole transmission, effectively decomposes the pulling force of cable transmission, then anchorage can be effectively ensured by the stronger shearing resistance of pile foundation
Basic does slipping property, it is ensured that Anchor Foundation is not along basal plane slip, the counterweight of anchorage top of concrete and the anchor of cable offside
The extraction-resistant behavior and anti-overturning of anchorage with larger withdrawal resistance, can be effectively ensured in bar.
