Subway evacuation platform plate with sound absorption function and preparation method
The invention belongs to the technical field of rail transit, and particularly relates to a subway evacuation platform plate with a sound absorption function and a preparation method, the subway evacuation platform plate comprises an evacuation platform and a ceramsite concrete layer attached to the back of the evacuation platform, so that the evacuation platform has sound absorption and noise reduction functions; the ceramsite concrete is prepared from the following components in parts by weight: 90 to 110 parts of ceramsite, 40 parts of cement, 1.2 parts of water reducing agent, 0.3 part of polyester fiber and the balance of water, and the water-cement ratio is 0.2 to 0.3. The subway evacuation platform plate disclosed by the invention has the effects of ensuring safety and stability of evacuated personnel, also has a good sound absorption effect, and is low in cost and simple in preparation method.
本发明属于轨道交通技术领域，尤其涉及一种含有吸音功能的地铁疏散平台板及制备方法,包括疏散平台及其背面附加的陶粒混凝土层，使疏散平台带有吸音降噪功能；所述陶粒混凝土包括以下重量份的组分及用量：陶粒、水泥、聚酯纤维和减水剂，其中陶粒90～110份，水泥用量40份，减水剂1.2份，聚酯纤维0.3份，其余为水，水灰比0.2～0.3。本发明中地铁疏散平台板具有疏散人员保证安全和稳固的作用外，还具有好的吸音作用，成本低，制备方法简单。
