The utility model discloses a muddy earth and the reinforcing bar of excelling in net, intensity is high, and the transition circular arc at bar hole edge has strengthened local strength on the panel, and the rigidity is good, non -deformable, it is outstanding to inhale the defening effect, and the leakproofness is good, can prevent effectively that the rainwater from getting into and hourglass sound.
Description
Technical field
The utility model discloses a kind of nonmetal compound Felt of sound barrier, be specifically related to a kind of nonmetal compound Felt of high speed railway sound barrier concrete.
Background technology
At present, high-speed railway noise treatment adopts the mode installing sound barrier, wherein most widely used with non-metal sound barrier again, non-metal sound barrier is made up of column and nonmetal compound Felt, development along with high-speed railway, the requirement of sound barrier is also more and more higher, and existing nonmetal compound Felt has been difficult to meet instructions for use in intensity, rigidity, sound absorption effect.
Utility model content
The deficiency existed for existing nonmetal compound Felt and defect, the utility model proposes the nonmetal compound Felt of a kind of intensity height, good rigidly, sound absorption excellent.
To achieve these goals, this utility model is achieved through the following technical solutions:
A kind of high speed railway sound barrier is with nonmetal compound Felt, for cube type, including panel, backboard, packing material and high-strength concrete layer, form cavity by high-strength concrete layer between described panel and backboard, and described panel is made up of slab reinforcement net, described backboard is made up of backboard bar-mat reinforcement, and the minor face position of described Felt is respectively symmetrically and is provided with boss and groove；Described panel is provided with at least one bar hole, and described bar hole edge is arc transition.
Further, described slab reinforcement net and backboard bar-mat reinforcement are by Ribbed Bar welding fabrication.
Further, the Ribbed Bar diameter of described backboard bar-mat reinforcement is more than the Ribbed Bar diameter of slab reinforcement net.
Further, described packing material is filled in the cavity of panel and backboard composition.
Further, described bar hole has gradient.
Further, described packing material is sound absorption material.
This utility model high speed railway sound barrier is with nonmetal compound Felt, compared with prior art have the advantage that the high-strength mixed earth of employing and bar-mat reinforcement, intensity is high, and the transition arc at bar hole edge enhances local strength on panel, good rigidly, is unlikely to deform, sound absorption excellent, good airproof performance, it is possible to effectively prevent rainwater from entering and leakage sound.
