深圳地鐵12號線(xiàn)全線(xiàn)貫通！為地鐵四期工程首條隧道貫通線(xiàn)路

人工智能朗讀：

深鐵集團相關(guān)負責人介紹，左太區間囊括了深圳地鐵建設領(lǐng)域的兩個(gè)“首次”，既是深圳地鐵建設領(lǐng)域首個(gè)下穿淺覆土海域的盾構隧道，也是首個(gè)采用泥水盾構機掘進(jìn)的區間。

此次貫通的左太區間是地鐵12號線(xiàn)貫通的關(guān)鍵控制點(diǎn)。施工方中國電建相關(guān)負責人介紹，左太區間穿越海域破碎帶是最考驗盾構施工技術(shù)和施工管理能力的重難點(diǎn)問(wèn)題，被列為深圳地鐵12號線(xiàn)最高風(fēng)險源，也是全線(xiàn)唯一的一級危險源。為了破解盾構穿越海域破碎帶的難題，深圳地鐵攜手中國電建及相關(guān)單位積極組織各方專(zhuān)家研討，將土壓平衡盾構機變更為泥水平衡盾構機，同時(shí)，不斷優(yōu)化施工方案，采取海面注漿加固斷層破碎帶、優(yōu)化刀具配備等措施，從技術(shù)層面降低施工風(fēng)險、確保施工安全。
