近日，由鐵建重工與中鐵隧道局聯(lián)合打造的國內(nèi)應(yīng)用最大直徑單護(hù)盾TBM（全斷面硬巖隧道掘進(jìn)機(jī)）“江漢云夢(mèng)號(hào)”在長(zhǎng)沙下線,。

Recently, "Jianghan Yunmeng", the single shield TBM (full-face hard rock tunnel boring machine) with the largest diameter applied in China, jointly developed by China Railway Construction Heavy Industry Co., Ltd. and China Railway Tunnel Group Co., Ltd., was rolled off the production line in Changsha.

“江漢云夢(mèng)號(hào)”開挖直徑12.23米，整機(jī)長(zhǎng)約140米，重約3200噸,，設(shè)計(jì)最小水平轉(zhuǎn)彎半徑600米，適應(yīng)最大坡度10%,，掘進(jìn)長(zhǎng)度11.77公里,，是國內(nèi)應(yīng)用的最大直徑單護(hù)盾硬巖掘進(jìn)機(jī)。

The "Jianghan Yunmeng" has an excavation diameter of 12.23 meters. The whole machine is about 140 meters long, weighs approximately 3,200 tons, has a designed minimum horizontal turning radius of 600 meters, can adapt to a maximum slope of 10%, and has a tunneling length of 11.77 kilometers. It is the single shield hard rock tunnel boring machine with the largest diameter applied in China.
