Description

Technical Field

[0001] The utility model belongs to the technical field of sound barrier preparation devices, and particularly relates to a preparation mold for an environmentally friendly sound barrier utilizing construction waste solid waste. Background Technique

[0002] Traffic noise is the main source of current urban noise, especially along urban expressways, highways, urban rail transit, and high-speed railways, where the noise problem is more serious. Noise has a great negative impact on the cardiovascular system, nervous system, reproductive system, endocrine system, and digestive system of humans, seriously damaging human health. Currently, the most important means of preventing and controlling traffic noise is to use sound barriers to absorb and isolate noise. Using foamed concrete to prepare the sound absorption module of the sound barrier is a widely used technology at present.

[0003] The sound barrier is generally a plate-like structure, and each sound barrier unit plate is connected together through columns, etc. The plate-like structure has problems such as being easily bent and deformed, and having low flexural strength and torsional strength. In order to improve the strength of the concrete sound barrier, it is generally achieved by increasing the cement dosage or the steel dosage (reinforcement ratio) of the concrete, but this method will lead to an increase in cost. Construction waste such as surplus mud, waste soil, coal cinder, and mortar generated during construction sites and enterprise production, and fly ash is the main solid waste of coal-fired power plants. Both are industrial waste residues with large current discharges. Utilizing industrial solid wastes such as construction waste and fly ash to prepare sound barrier noise reduction materials can effectively reduce the preparation cost of the sound barrier, and consume the solid waste materials, which is convenient and environmentally friendly.

[0004] Based on this, a preparation mold for an environmentally friendly sound barrier utilizing construction waste solid waste is proposed. Content of the Utility Model
