超長隧道風筒布采用怎樣的通風方式

        隧道施工風筒布山东11选5導風筒按照制作工藝分類:正工作壓力導風筒、氣體壓力導風筒,按照運用地理環境分為:媒礦導風筒和隧道工程施工導風筒。導風筒是一種引情欲生活的一種排風管,重要分為鐵質和PVC軟質吹風筒,鐵質吹風筒在好幾年前因為成本上升,運輸費用難。安裝不便,早就取代。現如今世界各地市場銷售都是用PVC軟質吹風筒。媒礦導風筒和隧道工程施工導風筒事實上本質沒什么區別,只不過運用的要求不一樣,根據國家MT164.2007要求,媒礦正工作壓力導風筒和氣體壓力導風筒,盡量阻燃等級抗靜電,一百米通風率盡量0.25以下,接口標準按照規定都是用鋼圈連接。
