Abstract
Steep Slope Bridge pier structure, to avoid occurring high steep excavation slope when steep slope section arranges Bridge Pier, and improves the horizontal force resistant ability to function of Bridge Pier.It comprises: pile foundation, and being arranged in the Rock And Soil of abrupt slope, bassets in its top; Bridge Pier, is consolidated in pile foundation top; Pier reinforcing body, outside is connected for overall with Bridge Pier, inner side and abrupt slope Rock And Soil close contact or overlap joint; Anchor cable, outer end is connected with Bridge Pier or pier reinforcing body, and inner end anchors in the Rock And Soil of abrupt slope.
Description
Technical field
The utility model relates to geotechnical engineering, particularly a kind of steep slope section Bridge Pier structure.
Background technology
Highway construction is built in mountain area, and the proportion of bridge and tunnel engineering is comparatively large, therefore the phenomenon of bridge on abrupt slope is very general.Bridge Pier due to the ability of its horizontal force resistant effect poor, therefore Bridge Pier is embedded in slope ground body under normal circumstances, when being positioned on abrupt slope, excavation abrupt slope is needed all to be embedded in slope ground body to meet Bridge Pier, thus make to have occurred a lot of Bridge Pier foundation ditch high slope, in some cases, Bridge Pier foundation ditch Reinforcing High Slope is very expensive very difficult with reinforcing.For this reason, a kind of Steep Slope Bridge pier structure of urgent needs solves problems.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Steep Slope Bridge pier structure, to avoid occurring high steep excavation slope when steep slope section arranges Bridge Pier, and improves the horizontal force resistant ability to function of Bridge Pier.
The utility model solves the technical scheme that its technical problem adopts:
Steep Slope Bridge pier structure of the present utility model, is characterized in that it comprises: pile foundation, and being arranged in the Rock And Soil of abrupt slope, bassets in its top; Bridge Pier, is consolidated in pile foundation top; Pier reinforcing body, outside is connected for overall with Bridge Pier, inner side and abrupt slope Rock And Soil close contact or overlap joint; Anchor cable, outer end is connected with Bridge Pier or pier reinforcing body, and inner end anchors in the Rock And Soil of abrupt slope.
The beneficial effects of the utility model are, can effectively avoid occurring high steep excavation slope when steep slope section arranges Bridge Pier, and improve the horizontal force resistant ability to function of Bridge Pier; This structure has easy construction, economy, the feature such as applied widely, has wide popularizing application prospect.
Accompanying drawing explanation
This manual comprises as next width accompanying drawing:
Fig. 1 is the structural representation of the utility model Steep Slope Bridge pier structure.
Component name shown in figure and corresponding mark: pile foundation 1, Bridge Pier 2, pier reinforcing body 3, anchor cable 4, abrupt slope Rock And Soil A.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Steep Slope Bridge pier structure of the present utility model comprises: pile foundation 1, and being arranged in the Rock And Soil A of abrupt slope, bassets in its top; Bridge Pier 2, is consolidated in pile foundation 1 top; Pier reinforcing body 3, outside is connected for overall with Bridge Pier 2, inner side and abrupt slope Rock And Soil A close contact or overlap joint; Anchor cable 4, outer end is connected with Bridge Pier 2 or pier reinforcing body 3, and inner end anchors in the Rock And Soil A of abrupt slope.
The utility model utilizes pile foundation 1 to elevate above the soil, and avoids Bridge Pier 2 excavation of foundation pit to form high gradient slope.Bridge Pier 2 is connected to form overall structure pile foundation 1, pier reinforcing body 3 is as the connecting media of Bridge Pier 2 and abrupt slope Rock And Soil A, horizontal resist forces is conducive to pass to Bridge Pier 2, thus increasing the horizontal force resistant ability to function of Bridge Pier 2, anchor cable 4 provides horizontal resist forces for Bridge Pier 2.This structure has easy construction, economy, the feature such as applied widely, has wide popularizing application prospect.
With reference to Fig. 1, the height that described pile foundation 1 is basseted forms slope height with Bridge Pier 2 excavation of foundation pit and suitably adjusts, and the height basseted in usual pile foundation 1 top is less than 10m.Described pier reinforcing body 3 adopts steel concrete and Bridge Pier 2 monobloc cast, and embed inside it in Rock And Soil A stabilized zone of abrupt slope, its insert depth is generally not less than 30cm.
With reference to Fig. 1, described anchor cable 4 anchors in stable abrupt slope Rock And Soil A, and it is constructed prior to Bridge Pier 2 and pier reinforcing body 3, before pier reinforcing body 3 is built, carry out stressed stretch-draw, and builds with it and connect into entirety.When abrupt slope Rock And Soil A is the better rock mass of stability, anchor cable 4 can adopt anchor pole form, and its length is generally not less than 10m.Anchor cable 4 or anchor pole can adopt single hole or porous reinforcement form, and determine according to the contact area of pier reinforcing body 3 with abrupt slope Rock And Soil A, contact area should adopt porous arrangement form greatly.
The above principle more of the present utility model that just explain through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
