Embodiment Construction

[0054] The present invention will be further described below in conjunction with drawings and embodiments.

[0055] Such as figure 1 , 2As shown, a highway sound barrier includes a column, a beam 2, an anti-collision structure 5, a rubber vibration isolation layer 4 and a sound-absorbing sound-insulating board. The anti-collision structure 5 is located on the outside of the road, and a rubber vibration isolation layer 4 is arranged on the top thereof. There are multiple uprights, which are located outside the anti-collision structure 5; adjacent uprights are connected by beams 2 at the same height. The column is inverted L-shaped, comprising a column vertical portion 11 and a column horizontal portion 12 at its top, the top of the column vertical portion 11 is fixedly connected to the fixed end of the column horizontal portion 12; the bottom of the column vertical portion 11 is fixed to the foundation Connected, and the lower end of the vertical part 11 of the column is pro...

Abstract

The invention provides an expressway sound barrier which comprises stand columns, cross beams (2), a collision avoidance structure (5), a rubber vibration isolating layer (4) and a sound absorbing and isolating plates. The collision avoidance structure (5) is located at the outer side of a road. The rubber vibration isolating layer (4) is arranged at the top of the collision avoidance structure (5). The multiple stand columns are located at the outer side of the collision avoidance structure (5). The adjacent stand columns are connected through the cross beams (2) located at the same height. Each stand column is in an inverted-L shape and comprises a stand column vertical part (11) and a stand column horizontal part (12) located at the top of the stand column, wherein the stand column vertical part (11) and the stand column horizontal part (12) are fixedly connected. The bottoms of the stand column vertical parts (11) are fixedly connected with a base, and stand column corner reinforcing ribs (13) are arranged at the lower ends of the stand column vertical parts (11). The noise reducing effect of the sound barrier is remarkable, a connecting device is designed reasonably, construction is convenient, connecting strength is high, and the sound barrier can be widely applied to the field of highways and railways.

Description

technical field [0001] The invention relates to the field of highways, in particular to a highway sound barrier. Background technique [0002] In recent years, with the rapid development of our country's economy, there are more and more expressways. While the development of expressways has brought convenient transportation, it has also caused a series of environmental problems, among which the problem of noise pollution is particularly prominent. To solve this problem, the common way is to set up sound barriers. But at present, the highway sound barriers used in our country have problems such as poor sound insulation effect, complicated installation structure, difficult construction and maintenance. Contents of the invention [0003] The technical problem to be solved by the invention is that the sound insulation effect of the existing expressway sound barrier is poor and the installation is complicated. [0004] In order to solve the problems of the technologies descri...
