地鐵8號線(xiàn)一期最后一個(gè)車(chē)站封頂！明年年底市民可乘車(chē)到鹽田看海

2019-12-10 07:00來(lái)源：深圳新聞網(wǎng)

大家可能會(huì )好奇，深外高中站和其他站有什么區別呢？上述文字可能會(huì )有點(diǎn)抽象，那么，小編就簡(jiǎn)單給大家講講施工難點(diǎn)。

1、站位特殊

作為一個(gè)明暗挖結合車(chē)站，也是深圳市軌道交通三期二階段工程中唯一一個(gè)大斷面暗挖車(chē)站（達365平方米）；

2、施工工藝復雜

設計采用雙側壁導坑法分九部分（九宮格）進(jìn)行開(kāi)挖，二襯施工需多次設置和拆除臨時(shí)支撐。

▲工人施工

由于深外高中站暗挖大斷面具有覆土小、跨度大、工序多、環(huán)境敏感等特點(diǎn)，車(chē)站施工難度高、施工風(fēng)險大。

為確保質(zhì)量、安全和工期目標，施工單位多次邀請知名業(yè)內專(zhuān)家組織方案優(yōu)化論證會(huì )，為施工質(zhì)量安全保駕護航。尤其是二襯方案的優(yōu)化，不僅提高了效率、節約了成本，更降低了施工風(fēng)險。
