Novel road sound-insulation wall

Abstract

The invention relates to a novel road sound-insulation wall, and belongs to the field of road traffics. The novel road sound-insulation wall comprises an H-shaped stand column, a sound-insulation plate, connectors, a deformed steel bar and a nut, wherein 3-5 stand column bolt holes are uniformly formed in a middle line of a wing edge of every side of the H-shaped stand column in the height direction; the sound-insulation plate is divided into three layers; the inner layer is an inner-layer corrugated plate, the middle layer is sound-insulation cotton, and the outer layer is an outer-layer steel plate; the connectors have symmetric E-shaped structures and are positioned on the left side and the right side of the sound-insulation plate; a transverse connector reinforcing plate is arranged inthe middle of the sound-insulation plate; the inner-layer corrugated plate is formed by bending a straight steel plate and consists of semi-circular sections and horizontal sections; the length of each horizontal section is 1 / 6-1 / 4 of the diameter of the corresponding semi-circular section; linearity is corrugations which are uniformly protruded; and the area of noise reflection of the sound-insulation plate can be increased. The novel road sound-insulation wall has the beneficial effects and advantages that the novel road sound-insulation wall is reliable in connection, high in joint strength, obvious in sound-insulation effect, convenient to convey, long in service life, short in construction period, simple to mount and convenient to maintain and repair, and assembled components can bedirectly prefabricated in factories.

Description

technical field [0001] The invention belongs to the field of road traffic, in particular to a novel road sound insulation wall. Background technique [0002] In the process of rapid economic development, along with the large-scale construction of roads, it also brings serious noise pollution. The noise generated does not affect the normal life of the residents on both sides. Usually, sound-absorbing panels are installed on both sides of the road. However, the sound-absorbing panels currently used on the roads cannot achieve true sound-absorbing effects, and their sound-insulating effects are not ideal. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a new type of road sound insulation wall, mainly for the purpose of developing a kind of reliable connection, high node strength, obvious sound insulation effect, convenient transportation, long service life, short construction period, simple installati...
