When ponding occurs in the upper surface of rainy day concrete layer 9, water carries out water conservancy diversion along water-guiding hole 10 and goes out, and prevents 9 upper surface of concrete layer
There is ponding, when rainwater is more, rainwater is flowed into the water guide groove 7 of two sides of the present invention, carries out water conservancy diversion row by water guide groove 7
Out, prevent 9 upper surface of concrete layer from generating excessive ponding.
Furthermore when generation beam wind generates the comprehensive movement in horizontal and vertical direction, the integrated stress of bridge is transmitted to
Spring in longitudinal buffer slot 11 and laterally buffering slot 13, the spring extruding force of generation are further transferred to first and second
Elastic layer uniformly divides elastic impact power since the first and second elastic layers are to be structure as a whole with entire backbone beam 1
It is scattered to entire bridge main body support construction, and reduces the destruction to spring mounting hole, additionally due to 11 hole of longitudinal buffer slot
The hole wall bottom end for being higher than laterally buffering slot 13 to bottom end of wall, therefore the horizontal direction deformation of backbone beam 1 caused by cross force
Can horizontal expansion deformation caused by the deformation interval of the vertical direction of backbone beam 1 caused by vertical force cancel out each other a part,
So as to reduce the synthesis deformation that backbone beam 1 is subject to, stress sensing unit is arranged in first the second elastic layer at this time can
Objectively to reflect the true internal stress that bridge is subject to.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
