Problems solved by technology

However, the current sound barriers often use a large number of metal material structures, especially on both sides of expressways and railways, where the lines are long and expensive, and management is inconvenient
If the metal material structure is used, the maintenance cost is high, and it is easy to cause damage and theft and fail to reach the normal service life

Embodiment Construction

[0014] Such as figure 1 , 2 , In the embodiment shown in 3, 4, and 5, a road sound insulation barrier is composed of a main structural member, a sound-absorbing panel (1), and a sound-insulation strengthening structure. The main structural components are composed of reinforced concrete base (2), structural columns (3), load-bearing beams (4) and concave tension beams (5). The structure is composed of sound insulation boards (6) and square diaphragm-shaped stiffeners (7), which are arranged in the direction facing away from the noise source, and flexible anti-crack mortar (8) is used as adhesive and plugging agent. The structural column (2) is prefabricated by reinforced concrete, and two grooves are arranged on the side of the structural column (3), the wide groove (9) is at the front, the narrow groove (10) is at the rear, and the structural column (2) The lower part is the base floor (11), and the base floor (11) has four installation holes (12), and the front and back of ...

Abstract

A road sound insulation barrier is composed of a main structural component, sound absorption plates and a sound insulation reinforcement structure. The main structural component is formed by reinforced concrete bases, structural columns, force bearing beams and concave tension beams, the sound absorption plates are arranged in the direction close to a noise source, the sound insulation reinforcement structure is formed by sound insulation plates and square insulation plate shape stiffening ribs and is arranged in the direction opposite to the noise source, and flexible anti-crack mortar is used as adhesives and filling agents. The structural columns, the force bearing beams and the concave tension beams are all prefabricated by reinforced concrete. The road sound insulation barrier has the advantages of being wide in material sources and low in manufacturing cost, and meanwhile accords with acoustic design standards, the use requirement for the sound insulation barrier is met, maintenance cost is low, and the service life is long.

Description

technical field [0001] The invention relates to a noise control technology, in particular to a road sound insulation barrier for blocking traffic noise on both sides of expressways and railways. Background technique [0002] A sound barrier is a sound insulation facility. In order to block the direct sound between the sound source and the receiver, a facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the impact of noise in a certain area where the receiver is located. Sound barriers are mainly used outdoors. As road traffic noise pollution becomes more and more serious, various forms of noise barriers are widely used to reduce traffic noise. [0003] With the development of society and the deepening of the awareness of the harmfulness of noise, people's demand for sound barriers that can reduce the impact of noise is increasing. However, the current sound insulation ...
