重庆地铁1号线月底开通 入地60米深全国之最
地铁1号线即将揭开神秘面纱。承载着山城人地铁梦想的1号线,KM电剪刀是如何在地形地貌特殊的山城地下修建的?我们能在其中感受到哪些国内首创的新技术?
昨日,国家地铁施工和验收规范编写组成员、重庆轨道集团专家组专家、副总工程师任今浩接受媒体 专访,上海空压机为读者揭秘地铁1号线建设的幕后故事。 施工过程有上万次爆破 要让地面人群感受不到 “在重庆建一个地铁站,要比其他地方多出四五个月时间。”上海电动卷帘门任今浩说,重庆的地质结构大多是岩石层,由于开挖难度大,地铁1号线建设一个车站的工期,要比北京、上海等 地多用四分之一的时间,比如大坪站,前前后后修了两年多。 高楼密集度高,也是重庆地铁建设难点之一。地铁1号线连通的沙坪坝区和渝中区是都市繁华区、交通要道和人口 密集地段,Marella 2011秋冬正品为了不破坏现有的交通,避免扰民,在开挖和爆破时对技术的要求非常高。油冷却器“地铁1号线在区间和站台开挖时,单次开挖面要求控制在20到30平方米,在爆破岩石层时,单次爆破长度不 能超过1.5米,爆破产生的震速必须低于1.5厘米/秒,高架站的施工也要求噪音控制在100分贝以下。”上海遥控车库门———任今浩解释了这一组数据代表的意义:也就是说,在1号线施工过程中,有上万次爆破作业,但要让地面人 群感受不到。 换乘通道不会人流交叉 乘客坠轨不会触电身亡 对于网络上盛行的地铁站触电、火灾等问题,任今浩的说法让大家消除了疑虑。 任今浩说,地铁1号线的换乘站点,除了较场口站尚未完工外,其余换乘通道也就百米左右,且拐弯不超过3个。 特别值得一提的是,出入口和部分换乘通道都是单向设计,乘客只能朝一个方向走,不会出现人流交 叉。 此外,地铁1号线采用的是单拱隔墙布局。也就是说,某一段地铁突发火灾时,上海遥控车库门烟雾、毒气不会蹿到反向的区间隧道里。此外,每个站之间相隔1.1公里,加上有大量排烟雾设施,一旦乘客遇 到紧急情况,可以迅速撤回站台,快速逃生。 另据介绍,地铁1号线的电力系统设在区间和站台顶端,Marella 2011秋冬正品隧道顶部安装了电力触碰网,从车厢顶部接受供电和动力支持,而不是现在使用的从地面铺设电力系统,这样安全 系数就大得多,即使发生乘客意外坠入轨道事故,也不会因此触电身亡。 总工程师揭秘地铁1号线 马家岩站年底投入使用 位于60多米深岩石层中 即将开通的地铁1号线沙坪坝至较场口段共12个站点,KM电剪刀月底开通后仅停靠11个,马家岩站由于站场建设尚未完成,线异物检查机暂时不停靠,按规划将在年底前投用。就是这个暂不开通的车站,头上也有一个最———目前我国最 深的地铁站。 任今浩说,MaxMara 意大利代购地铁1号线全线共23个车站,只有较场口、两路口、石油路、石桥铺4个车站是在路面上开挖的,其余19个车 站都位于地下,大多数离地面40多米,而马家岩车站位于60多米深的岩石层中。如果从售票站厅出发,需要乘 坐3部超长自动扶梯才能回到地面,这也创造了国内地铁建设之最。 马家岩车站为什么要建这么深?任今浩说,油冷却器主要是根据地下空间结构决定的。按照国家地铁施工和验收规范,地铁的爬坡度是千分之三十,也就是说列车每前 行1000米,坡度可以升高或降低30米。地铁1号线的爬坡能力比国家标准还略高,上海空压机达到了千分之三十五。但由于地铁1号线各车站之间的坡度比较大,按照规范计算,车站就只能建在60米深的地 下了。 拱顶售票站厅没有柱子 弧形设计犹如时空隧道 地下40多米深处的地铁车站是什么样?昨日,重庆晚报记者走进大坪车站提前打探。 与想象中的低沉昏暗大相径庭,大坪车站宽敞明亮,售票站厅造型和壁面都是弧形设计,犹如一段时空隧道,暗红 色顶棚上嵌着白色铝合金钢管,像跳跃的琴键,也像夜晚的星空。更巧妙的是,这些钢管遮住了暗色顶棚上的电气 管道,增加了美感。MaxMara 意大利代购此外,站厅采用拱顶,空高约在5米,比一般的轨道交通站台高出一到两米。站厅跨度达21米,纳米级二氧化钛,却没有以往在轻轨站常见的大柱子支撑。 任今浩说,在地铁1号线的所有地下车站,售票站厅都没有一根柱子,柱子仅仅出现在站台。市民不要认为这样不 安全,线异物检查机因为重庆的地下是岩石结构,非常坚硬,加上采用一次性浇筑技术,能保证安全。目前,地铁1号线整体工程设计 可以抗击的地震烈度为7度。 两个站点 换乘轻轨 在地铁1号线通车后,市民可以通过在轨道交通1、2号线之间换乘,空压机维修直抵渝中区、沙坪坝区、九龙坡区和大渡口区。重庆晚报记者了解到,市民可以通过两个站点实现轨道交通的换乘 ,分别是大坪站和较场口站。 大坪站:换乘轻轨不超五分钟 地铁1号线大坪车站在地下40多米处,位于轻轨2号线大坪站上方。 与轻轨2号线一样,大坪地铁站同样分为售票站厅和站台候车厅两层。上海空压机如果乘客从2号线下车转到1号线,需先爬上20多步台阶或乘坐扶梯进入售票厅,然后按照指示牌指示步行约2 0米,一个小拐弯后,就可看到通往1号线售票站厅的阶梯。 这个阶梯共有4组,每组16梯,可以选择步行爬梯,或者选择两侧的自动扶梯,就可进入1号线售票厅。从这里 进入候车站台共有两个入口,需要下行30多个台阶。 这样走一遍下来,从2号线下车到1号线上车,油冷却器除了爬梯直行只有50米左右,时间不会超过5分钟。当然,如果你行动不便或带有大件行李,也可选择乘坐直梯 ,更为简单方便。 较场口站:暂时需要出站换乘 与大坪站的十字换乘不同,检针机较场口站需要走出车站才能实现换乘。 最近的换乘通道应该在1、2号出口。从2号线的B出口出站后,穿过日月光广场进入商场内,就能看到地铁出入 口标志,位于商场的LG层。B1层是日月光广场负一楼,B2层是尚未投用的门面,B3层则是售票站厅和安检 闸口,然后通过B4层站台上车,空压机维修每层约需经过一段30级台阶左右的步行路程,走一遍约耗时10分钟。 另外还有3、4号出口可以换乘。从2号线较场口站的A1、A2出口出发,穿过一条马路抵达城市阳台,然后继 续沿中兴路下行,再次穿过马路,就能分别到达1号线的3、4号出口。如果从2号线站厅算起,这段路程约40 0米,时间约10分钟。上海空压机到达出入口再经过百米左右的通道和一组台阶,就能进入站厅了。 重庆晚报记者了解到,目前1、2号线的较场口站暂时未实现地下通道通行,不过不久后将会建成。 |
