Abstract
The invention discloses a kind of suspension cable ground anchor structure, including suspension cable and Stay Cable Anchors, and group's rope rock anchorage beam of reinforced concrete structure, the bottom of group's rope rock anchorage beam is fixedly connected with anchoring pile foundation, suspension cable connects Stay Cable Anchors through group's rope rock anchorage beam, group's rope rock anchorage beam be located at the part below ground line and anchoring cavity is provided with inside it, and Stay Cable Anchors, which are arranged at, to be anchored in cavity.When anchor beam is slightly above ground, suspension cable anchor structure is overall in natural moving air, avoids corrosion of the humid air to suspension cable anchor structure, can be treated by usual suspension cable.When suspension cable does not have condition to utilize gravity-flow ventilation, then an anchoring cavity is manufactured in anchor beam, weathering is inside set and avoids ponding, and set ventilation hole.The present invention solves the problems, such as the anti-corrosive durability of suspension cable rock anchor (or earth anchor), for the varying environment residing for rock anchor, has carried out, for design, having preferable practical function, and of low cost, can widely use.
Description
Technical field
The present invention relates to stayed-cable bridge girder construction technical field, in particular to a kind of suspension cable ground anchor structure.
Background technology
Rock anchor (or earth anchor) sunpender of short stockaded village's bridge is in order to solve the Anticorrosion of stayed structure rock anchor, sometimes using carbon
Fiber drag-line, but the cost of CFRP cable is higher, and import is needed, therefore do not possess the condition largely used.For drag-line rock
Anchor, it is crucial that the anti-corrosive durability problem of drag-line and its anchor structure, although the anti-corrosive durability of Carbon Fiber Cables is good, mesh
The opportunity widely applied in preceding engineering is also immature.
The content of the invention
Present invention aim to solve the deficiency of above-mentioned background technology, there is provided a kind of simple in structure, antiseptic and rustproof effect
Fruit is good, suspension cable ground anchor structure of low cost.
In order to achieve this, the suspension cable ground anchor structure designed by the present invention, including suspension cable and Stay Cable Anchors, and
Group's rope rock anchorage beam of reinforced concrete structure, the bottom of group's rope rock anchorage beam are fixedly connected with anchoring pile foundation, the oblique pull
Rope is located at the part below ground line inside it and is provided with anchor through group's rope rock anchorage beam connection Stay Cable Anchors, group's rope rock anchorage beam
Gu cavity, the Stay Cable Anchors are arranged in anchoring cavity.
Further, the anchoring cavity is communicated with multiple air intake passages, and the air inlet of the air intake passage is opened in group
On the side surface of rope rock anchorage beam.
Further, the cavity bottom surface of the anchoring cavity is an inclined plane with the horizontal angle, group's rope
The end of rock anchorage beam is provided with the osculum connected with anchoring cavity.
Preferably, the angle of the cavity bottom surface and horizontal plane is 1 °~5 °.
The beneficial effects of the invention are as follows：When anchor beam is slightly above ground, suspension cable anchor structure is overall empty in flowing naturally
In gas, corrosion of the humid air to suspension cable anchor structure is avoided, can be treated by usual suspension cable.When suspension cable does not have condition
During using gravity-flow ventilation, then an anchoring cavity is manufactured in anchor beam, weathering is inside set and avoids ponding, and set ventilation hole.This hair
The bright anti-corrosive durability for solving the problems, such as suspension cable rock anchor (or earth anchor), for the varying environment residing for rock anchor, has carried out pin
To design, there is preferable practical function, and it is of low cost, it can widely use.

Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Suspension cable ground anchor structure as shown in Fig. 1-4, including suspension cable 1 and Stay Cable Anchors 2, and armored concrete
Group's rope rock anchorage beam 3 of structure, the bottom of group's rope rock anchorage beam 3 are fixedly connected with anchoring pile foundation 4, and suspension cable 1 passes through group's rope rock anchor
Beam 3 connects Stay Cable Anchors 2, and group's rope rock anchorage beam 3, which be located at the part below ground line and is provided with inside it, anchors cavity 5, suspension cable
Anchorage 2 is arranged in anchoring cavity 5.Anchoring cavity 5 is communicated with multiple air intake passages 6, and the air inlet of air intake passage 6 is opened in group
On the side surface of rope rock anchorage beam 3.The cavity bottom surface 7 of anchoring cavity 5 is an inclined plane with the horizontal angle, group's rope rock anchorage beam
3 end is provided with the osculum connected with anchoring cavity 5.Cavity bottom surface 7 and the angle of horizontal plane are 2 °.
In the present invention, Fig. 1 is the arrangement schematic diagram of tilting group's rope rock anchorage beam 3, is adapted to feelings of the landform there are the corresponding gradient
Condition, Fig. 2 are the arrangement schematic diagram of horizontal group's rope rock anchorage beam 3, are adapted to the relatively flat situation of landform.The section B of Fig. 2-
B (Fig. 4) is partly slightly above the part on ground for group's rope rock anchorage beam 3, and 1 anchoring system of suspension cable does not have in natural moving air
Etching problem caused by humid air, can treat by usual suspension cable.Section A-A that Fig. 3 is Fig. 2 is no condition profit
With the part of gravity-flow ventilation, one anchoring cavity 5 of manufacture in group's rope rock anchorage beam 3,5 bottom surface of anchoring cavity avoids accumulating for weathering
Water, and air intake passage 6 is set, dry wind is sent using artificial if no condition sets air intake passage 6, or charcoal is stacked using ancient method
With lime.
The above described is only a preferred embodiment of the present invention, not the structure of the present invention is done in any form
Limitation.Any simple modification, equivalent change and modification that every technical spirit according to the present invention makees above example,
In the range of still falling within technical scheme.
