"今年上半年，我们完成了4号线中央商务区站2道门洞的搭建，这两天开始搭建11号线盾构门 洞。"近日，在江北新区地下空间一期现场，数十米深的地下，为迎接地铁盾构机到来的新门洞正式开 装。 记者从江北商务区站走进地下30多米深处，这里主体结构已完工，部分支撑梁开始拆除。基坑底 部，两道半圆形钢环已就位，其中左侧完成第一步安装。 "之所以是半环，是因为上部支撑梁尚未拆除，工人可利用支撑梁将半环安装好，待拆除后再完成 整道钢环门洞安装。"地下空间一期施工总包单位中国能建葛洲坝一公司工区负责人占士军向记者介 绍，这里的最底层是未来地铁11号线的穿行区域。目前11号线沿途各站点和区间盾构正在加快施工， 而搭设门洞，则是将地铁盾构机引入地下空间，从而实现区间的贯通。 在支撑梁上，工人陈师傅正和工友们安装吊装滑轮，并将钢链投放至钢环所在位置。现场巨大 的"风口袋"增加地下的空气循环，空中喷洒的水雾为施工环境带来凉意。陈师傅等人在坑底工人配合 下，将利用滑轮拉起数吨的钢环，贴墙固定。而在该空间另一端，还有2道承接11号线盾构机的门洞也 将搭建。 不远处，记者看到了已经安装完成的地铁4号线钢环门洞，其轨行区走向与11号线呈十字交 ...
