Effect is preferable, can meet the requirement for obstructing a variety of sensitive point for noise.
Further, the shape of cross section of the column is H types.
By using above-mentioned technical proposal, the recess of H type columns both sides is available for Felt to install, and Felt
Thickness as the depth of H type column recess, be more firmly mounted Felt, while H type column large carrying capacities,
Structural strength is high, and bending resistance is strong.
Further, the column lower end is fixed with pedestal bottom plate, and the pedestal bottom plate is provided with bolt hole, the bolt
The bolt with concrete guardrail dismantling connection is provided with hole.
By using above-mentioned technical proposal, pedestal bottom plate, increase and the contact area on ground are provided with below column, is passed through
Column is fixed on concrete guardrail by dismountable bolt, easy disassembly.
Further, the pedestal bottom plate is provided with reinforcement.
By using above-mentioned technical proposal, reinforcement provides additional stiffness, can accordingly reduce pedestal bottom plate thickness, improves vertical
The intensity of column bottom.
Further, the Felt is provided with protection network away from highway side.
By using above-mentioned technical proposal, when traffic accident collision Felt occurs for vehicle and causes Felt to be broken
When, protection network can be protected to personnel and vehicle.
In summary, the utility model has the advantages that：
1st, using the acoustic material of different performance, the characteristic having using each acoustic material, it is used in combination, sends out in sound insulation
The advantage of each acoustic material is waved, improves the overall sound insulation value of road noise barrier；
2nd, it is arranged to vacuum between noise reducing plate and sound panel, make use of the principle of vacuum not acoustic, improve Felt
Soundproof effect；
3rd, sound panel both sides set interlaced noise insulation block, the noise insulation block in outside can to adjacent two noise insulation block of inner side it
Between the noise that spreads out of obstructed, be effectively reduced influence of the noise to resident.
