春風(fēng)隧道工程即將掘進(jìn) 中國最大直徑盾構機“春風(fēng)號”露真容

春風(fēng)隧道施工現場(chǎng)

結合深圳地區復雜的地質(zhì)情況，“春風(fēng)號”盾構機在設計中采用了常壓換刀技術(shù)，增加了超前鉆機、超前地質(zhì)預報系統、艙內監控,針對以花崗巖、石英巖為主的全斷面硬巖對設備造成的嚴重磨損問(wèn)題，采用在刀盤(pán)外周焊鑲耐磨復合鋼板的方式，加強了刀盤(pán)、刀具、泥水環(huán)流系統的耐磨性,并配置磨損、溫度、轉速檢測裝置，渣土二次破碎系統、中心刀沖刷系統。一系列的設計改良和技術(shù)革新，極大地降低了設備損耗和作業(yè)風(fēng)險，提高了作業(yè)效率。
