Abstract
The honest safeguard structure of mud-rock flow district bridge, honest effectively to avoid mud-rock-flow-impact to destroy bridge, and be easy to construction, and be conducive to reducing construction costs.This safeguard structure comprises: anchor pile, and be disposed in the ground of the honest mud-rock-flow-impact side of bridge, basset 2 ~ 3m on stake top; Anti-collision wall, is arranged on the ground of the honest mud-rock-flow-impact side of bridge, fixes as one with anchor pile; Elastic cord breaker, is fixedly installed on the anti-mud-rock-flow-impact side of anti-collision wall.
Description
Technical field
The utility model relates to geotechnical engineering, and the bridge that particularly mud-rock-flow-impact can be very large earnestly protects.
Background technology
Mud-rock flow is extremely grown in Southwestern China mountain area, when highway construction is passed through by usually adopting type of bridge during debris flow gully, but when debris flow gully is wider, bridge by time also need to arrange bridge in cheuch honest, to reduce bridge engineering investment, bridge is earnestly arranged in debris flow valley the impact that will inevitably be subject to mudstone and impact, must take measures earnestly to protect bridge, particularly when mud-rock-flow-impact can very large time, effectively protection is earnestly carried out to bridge just very crucial, for this reason, the urgent honest safeguard structure of a kind of mud-rock flow district bridge that needs solves problems.
Summary of the invention
Technical problem to be solved in the utility model is to provide the honest safeguard structure of a kind of mud-rock flow district bridge, honest effectively to avoid mud-rock-flow-impact to destroy bridge, and is easy to construction, and is conducive to reducing construction costs.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
The honest safeguard structure of mud-rock flow district bridge of the present utility model, is characterized in that it comprises: anchor pile, and be disposed in the ground of the honest mud-rock-flow-impact side of bridge, basset 2 ~ 3m on stake top; Anti-collision wall, is arranged on the ground of the honest mud-rock-flow-impact side of bridge, fixes as one with anchor pile; Elastic cord breaker, is fixedly installed on the anti-mud-rock-flow-impact side of anti-collision wall.
The cross section of described anti-collision wall is trapezoidal, and its end face is relative with mud-rock-flow-impact direction.
The beneficial effects of the utility model are, can effectively avoid mud-rock-flow-impact to destroy bridge honest, thus the safety of protection bridge earnestly in mud-rock flow groove, structure is simple, and easy construction, construction costs is low, has wide popularizing application prospect.
Accompanying drawing explanation
This manual comprises following two width accompanying drawings:
Fig. 1 is the schematic cross-sectional view of the honest safeguard structure of the utility model mud-rock flow district bridge.
Fig. 2 is the floor map of the honest safeguard structure of the utility model mud-rock flow district bridge.
Component name shown in figure and corresponding mark: anchor pile 1, anti-collision wall 2, elastic cord breaker 3, the honest A of bridge.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2, the honest safeguard structure of mud-rock flow district bridge of the present utility model comprises: anchor pile 1, and be disposed in the ground of bridge honest A mud-rock-flow-impact side, basset 2 ~ 3m on stake top; Anti-collision wall 2, is arranged on the ground of bridge honest A mud-rock-flow-impact side, fixes as one with anchor pile 1; Elastic cord breaker 3, is fixedly installed on the anti-mud-rock-flow-impact side of anti-collision wall 2.
The utility model utilizes anchor pile 1 to fix anti-collision wall 2, utilizes anchor pile 1 and anti-collision wall 2 to bear the impulsive force of mud flow, thus the safety of the honest A of protection bridge, utilize cushion coat 3 to cushion the impact energy of mud-rock flow, avoid anti-collision wall 2 to occur hard impact failure.It is honest that this structure can effectively avoid mud-rock-flow-impact to destroy bridge, thus the safety of protection bridge earnestly in mud-rock flow groove, structure is simple, and easy construction, construction costs is low, has wide popularizing application prospect.
With reference to Fig. 2, for being conducive to structure stress and carrying out water conservancy diversion to mud-rock flow, the cross section of described anti-collision wall 2 is trapezoidal, and its end face is relative with mud-rock-flow-impact direction.For strengthening Structure and stability and anti-impact force, described anchor pile 1 presses triangle or trapezoidal shape is laid.
Described anti-collision wall 2 rational height should be close with mud-rock-flow-impact height, and concreting or mortar flag stone can be adopted to build by laying bricks or stones, and the Ullage of itself and the honest A of bridge is no less than 1m.Described cushion coat 3 rational height is highly consistent with anti-collision wall 2, and junked tire colligation can be adopted in the shock resistance side of anti-collision wall 2.
Some principles of the above honest safeguard structure of the utility model mud-rock flow district bridge that just explains 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.
