Abstract
The invention discloses a stay cable ground anchor structure. The stay cable ground anchor structure comprises stay cables, a stay cable anchorage device and a group cable rock anchor beam adopting a reinforced concrete structure, wherein anchoring pile foundations are fixedly connected to the bottom of the group cable rock anchor beam; the stay cables penetrate through the group cable rock anchor beam to be connected with the stay cable anchorage device; and an anchoring cavity is formed in the inner part, of the part, located under the ground level, of the group cable rock anchor beam, and the stay cable anchorage device is arranged in the anchoring cavity. When the anchor beam is slightly higher than the ground level, the stay cable anchoring structure is in natural flow air wholly, so that the condition that the stay cable anchoring structure is corroded by humid air is avoided, and the stay cable anchoring structure can be treated as a conventional stay cable. When the stay cables cannot use natural ventilation, the anchoring cavity is formed in the anchor beam, and a drainage slope is arranged in the anchoring cavity, so that water accumulation is avoided; and ventilation holes are formed. According to the stay cable ground anchor structure disclosed by the invention, the problems of the anti-corrosive properties and the durability of the stay cable rock anchor (also called ground anchor) are solved. In accordance with different environment of the rock anchor, specific design is performed, so that the stay cable ground anchor structure has good practical effects, is low in cost and can be widely used.
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) suspension rod of short stockaded village's bridge 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 for using in a large number.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 cables is good, but mesh
The opportunity widely applied in front 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 structure, antiseptic and rustproof effect
Really good, with low cost suspension cable ground anchor structure.
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 is fixedly connected with anchoring pile foundation, the oblique pull
Rope connects Stay Cable Anchors through group's rope rock anchorage beam, and group's rope rock anchorage beam is located at the part below above-ground route and is provided with anchor inside it
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, it is described anchoring cavity cavity bottom surface be one with the horizontal angle inclined plane, group's rope
The end of rock anchorage beam is provided with the osculum connected with anchoring cavity.
Preferably, the cavity bottom surface and the angle of horizontal plane are 1 °～5 °.
The invention has the beneficial effects as follows：When anchor beam is slightly above ground, suspension cable anchor structure is overall in the sky that flows naturally
In gas, it is to avoid corrosion of the humid air to suspension cable anchor structure, can treat by usual suspension cable.When suspension cable does not have condition
Using an anchoring cavity during gravity-flow ventilation, is then manufactured in anchor beam, inside set weathering and avoid hydrops, and set air vent.This
The bright anti-corrosive durability for solving the problems, such as suspension cable rock anchor (or claiming earth anchor), for the varying environment residing for rock anchor, has carried out pin
It is with preferable practical function and with low cost to design, can widely use.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail with specific embodiment.
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 is 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 is located at the part below above-ground route and anchoring cavity 5, suspension cable are provided with inside it
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.Anchoring cavity 5 cavity bottom surface 7 be one with the horizontal angle inclined plane, group's rope rock anchorage beam
3 end is provided with the osculum connected with anchoring cavity 5.Cavity bottom surface 7 is 2 ° with the angle of horizontal plane.
In the present invention, Fig. 1 is the arrangement schematic diagram of tilting group's rope rock anchorage beam 3, is adapted to the feelings that landform has the corresponding gradient
Condition, Fig. 2 is the arrangement schematic diagram of horizontal group's rope rock anchorage beam 3, is 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 the anchoring system of suspension cable 1 does not have in natural moving air
The etching problem that humid air causes, can treat by usual suspension cable.Fig. 3 is without condition profit for the section A-A of Fig. 2
With the part of gravity-flow ventilation, one anchoring cavity 5 of manufacture in group's rope rock anchorage beam 3, the anchoring bottom surface of cavity 5 avoids product for weathering
Water, and air intake passage 6 is set, adopt if air intake passage 6 is set without condition and manually send dry wind, or Linesless charcoal is stacked using ancient method
With Calx.
The above, is only presently preferred embodiments of the present invention, not does any pro forma to the structure of the present invention
Limit.Any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example,
