Description
Technical field
The invention belongs to bridge structure technical field, relate to anchorage and the bridge abutment structure of horizontal drawing cable bridge, especially relate to a kind of horizontal drawing cable bridge steel wire rope self-anchored type bridge abutment structure.
Background technology
The feature of horizontal drawing cable bridge is that floorings are laid immediately on main rope (cable wire), and for ensureing the normal traveling of vehicle, it is necessary to less main rope sag, thus main rope tension is relatively big, and the quantity of main rope is also more.Horizontal drawing cable bridge requires over anchorage device and is anchored at by main rope in the abutment of two sides or in massif.Anchorage is the key issue of horizontal drawing cable bridge, as shown in Figure 1, traditional be main rope with steel wire rope 1 horizontal drawing cable bridge anchorage structures be adopt special anchor pole 2, its one end is welded on special anchor plate 7, anchor plate 7 is then fixed on armored concrete anchorage beam 6, and the other end is connected with main rope by adapter 5 or actuator.In traditional anchorage structures, need first to build in concrete by anchor pole 2 and anchor plate 7, reach to install again after intensity main rope until concrete.Main rope and the connection of anchor pole 2 are the corresponding anchor poles 2 of main rope, and therefore the quantity of anchor pole 2 is identical with main rope, and anchor pole 2 is positioned by anchor rod locating device 8.Owing to anchor pole 2 stress is relatively big, high-strength steel need to be adopted to make；Equally, adapter 5 or actuator are also required to adopt high-strength steel.
In order to overcome in tradition horizontal drawing cable bridge anchorage structures because of relatively big and main rope the more existing deficiency of quantity of main rope tension, at present, in bridge structure is constructed, occur in that various anchorage structures.Chinese patent if the number of disclosing is CN203411900U discloses the anchor plate structure of a kind of horizontal drawing cable bridge, including anchor pole, bearing plate and floor, described bearing plate and floor weld together, anchor pole is welded on floor both sides through the preformed hole on bearing plate, described bearing plate is perpendicular to horizontal plane, and orthogonal with bridge axes, bearing plate is provided with mean for the hole of anchor pole traverse, the quantity in hole and position and anchor pole match.This structure can guarantee that the layout ratio of anchor pole is more uniform, improves the globality of abutment, and the requirement of ground is reduced.But the site operation welding quality of anchor pole and floor is often difficult to ensure that, bridge security is constituted a threat to.For another example, the Chinese patent that publication number is CN203411902U discloses a kind of callable horizontal drawing cable bridge anchor plate structure, including anchor pole and bearing plate, described bearing plate is sleeved on anchor pole, bearing plate side is provided with malthoid, opposite side is provided with razor-edge liner, and razor-edge liner is fixed on anchor pole by nut, and the one end being connected with bearing plate on anchor pole is provided with the screw thread matched with nut.This structure can guarantee that the layout ratio of anchor pole is more uniform, improves the globality of abutment, the recoverable such as anchor pole, anchor plate.But fixing owing to anchor pole and bearing plate are connected by nut, it is unreliable to connect, and anchor pole easily producing in concreting process shifts.And for example, publication number is the anchorage structures that the Chinese patent of CN203411901U discloses a kind of horizontal drawing cable bridge, including longitudinal cable wire, connecting device, anchor pole, anchorage beam and anchor, described longitudinal cable wire is connected with anchor pole by connecting device, anchor pole is connected with anchor, and anchor is connected with anchorage beam.Described anchor pole adopts some to be arranged in parallel, and the quantity of anchor pole and longitudinal cable wire one_to_one corresponding.The distribution ratio of this structural load is more uniform, considerably increases the safety of bridge；Being absent from angle between anchor pole and cable wire, structure stress is clear and definite, can shorten the length of anchor pole simultaneously.But anchor pole requires over anchor and is accurately positioned, and need to ensureing that in concreting process anchor pole does not shift, field control difficulty is bigger.
In sum, there is following deficiency at existing horizontal drawing cable bridge anchorage structures:
(1) owing to anchor pole and adapter need to adopt high-strength steel, it is easy to produce brittle break, welding requirements is also very harsh, and site operation welding quality is often difficult to ensure that, bridge security is constituted a threat to；
(2) anchor pole, adapter and actuator quantity are many, processing trouble；And installation accuracy requires height, anchor pole requires over positioner and is accurately positioned, and need to ensure that in concreting process anchor pole does not shift, and field control difficulty is bigger；
(3) owing to main rope (steel wire rope) is to be connected with adapter by rope sling, rope sling and adapter and actuator take longer distance (namely backbar and cable saddle between) along bridge to needs at cable bridge, not only cause and between backbar and cable saddle, need more complicated structure to process the connectivity problem of floorings, and if two sides landform is restricted, the radius of turn of bridge approach is extremely difficult to requirement；
(4) anchor pole and adapter are expensive, and anchorage structures cost is high.
Summary of the invention
It is an object of the invention to overcome deficiency existing in existing horizontal drawing cable bridge anchorage structures, the present invention provides a kind of horizontal drawing cable bridge steel wire rope self-anchored type bridge abutment structure.Thus improving the safety of horizontal drawing cable bridge anchorage, simplifying bridge structure, reducing site operation and installation difficulty, save construction investment.
The present invention is achieved by following technical solution.
A kind of horizontal drawing cable bridge steel wire rope self-anchored type bridge abutment structure, including anchorage beam, cable saddle and the steel wire rope connecting anchorage beam and cable saddle, it also includes cable saddle basis, strut beam and backfill body, described cable saddle is arranged on cable saddle basis, strut beam is arranged on anchorage beam, described steel wire rope is bearing on cable saddle, and the end of steel wire rope is weaved into rope sling and is connected with strut beam, and it is internal that described cable saddle to the steel wire rope between anchorage beam, rope sling and strut beam is all wrapped in backfill.
Described anchorage beam is reinforced concrete structure.
Described anchorage beam be shaped as the rectangular structure that top is tooth-like recesses.
Described anchorage beam is provided with pre-embedded steel slab near strut beam one end.
Described strut beam is welded by round steel pipe and supporting plate, and supporting plate welds with the pre-embedded steel slab being embedded on anchorage beam, makes strut beam be fixed on anchorage beam.
