全長(cháng)710米！亞洲最長(cháng)單體地鐵站雛形初現，就在深圳平湖

2018-10-29 06:04來(lái)源：深圳特區報

采用數碼雷管爆破，降噪降塵減少“擾民”

10月28日，記者來(lái)到施工現場(chǎng)，雙擁街站位于平湖雙擁街，周邊是建筑密集的繁華商業(yè)區。深圳地鐵集團建設總部相關(guān)負責人表示，這座車(chē)站基坑據建筑物最小距離僅為5.16米，基坑內地質(zhì)條件復雜，石方量高達41.5%，給施工帶來(lái)了極大的挑戰。為了減少施工對居民生活的影響，深圳地鐵組織知名專(zhuān)家進(jìn)行現場(chǎng)考察，反復研討并進(jìn)行現場(chǎng)試爆，最終確定采用電子數碼雷管進(jìn)行爆破施工。

據介紹，電子數碼雷管爆破具有使用安全可靠、延時(shí)精確度高、設定靈活等特點(diǎn)，既降低了粉塵和噪聲影響，又減小了爆破振速，同時(shí)提高了施工效率。施工單位中國鐵建相關(guān)負責人告訴記者，10號線(xiàn)自去年6月進(jìn)行首次爆破以來(lái)，在長(cháng)達13個(gè)月的施工中未發(fā)生一次安全事故，并于今年7月17日順利完成主體基坑全部爆破施工。
