目前国内主要地下隐蔽部和国外地下工程,用得较广泛的除湿措施是:升温通风除湿;冷却除湿;吸湿剂吸湿等。这些机械除湿方法,运行费用和耗能量都比较高,一次性投资亦比较高。根据我国的国情,普通地下工程采用机械除湿暂时还做不到。国内地下工程机械消音用得很少,一九七五年以前,国内地下工程多数采用木丝板做内衬作为消音处理;一九七五年以后,采用泡沫塑料作为消音材料日益增多。木丝板木骨架极容易腐烂;泡沫塑料板钢骨架成本比较高,时间稍长钢材亦易受侵蚀。能有一种原材料:成本,耐高温、抗腐性强、容重轻、孔隙率大,制作安装工艺简便、能配制成有一定抗压强度的建筑材料,取代工厂生产的各类消音材料,同时又能降低温度是最理想的。
At present, the main underground concealment department and foreign underground projects, the most widely used dehumidification measures are: warming, ventilation, dehumidification, cooling, dehumidification, moisture absorption, and moisture absorption. These mechanical dehumidification methods have relatively high operating costs and energy consumption, and one-time investment is also relatively high. According to China’s national conditions, ordinary underground engineering using mechanical dehumidification temporarily can not do. The use of domestic underground construction machinery has been seldom used for mufflers. Before 1975, the majority of domestic underground constructions used wooden linings as linings for silencing treatment; after 1975, the use of foamed plastics as silencing materials was increasing. Wooden wood frame skeleton is very easy to rot; foam plastic plate steel skeleton cost is relatively high, the time is slightly longer steel is also vulnerable to erosion. Can have a kind of raw material: cost, high temperature resistance, strong corrosion resistance, light weight, porosity, production and installation process is simple, can be formulated into a building material with a certain compressive strength, to replace the factory production of various types of silencing materials, at the same time It is ideal to lower the temperature.
