新京报讯 (记者马力)备受关注的北京新机场即将进入实质性建设。北京城建集团和北京建工集团昨日均发布了其中标新机场工程的消息。消息透露,新机场航站楼的计划建成时间为2019年7月15日。

确定采用“海星”方案

据介绍,北京新机场航站区总用地面积约27.9公顷,南北长1753米,东西宽1591米,由旅客航站楼、换乘中心和综合服务楼与停车楼三部分组成,总建筑面积103万平方米,超过了首都国际机场T3航站楼,是目前全球最大的机场航站楼,计划于2019年7月15日建成。

记者从两家单位发布的中标信息中发现,北京新机场最终采用的是“海星”设计方案,五座向外伸出的指廊与航站楼主体组成了一个类似海星的图案。

航站楼屋面最高50米

此次北京城建集团中标的是“北京新机场旅客航站楼及综合换乘中心工程(核心区)”,其总建筑面积约60万平方米,造价63.9亿元,合同工期1218日历天,计划2019年7月15日竣工。

记者从城建集团了解到,航站楼核心区是整个航站楼的主要功能区,地下二层、地上五层。其中地下二层为高速铁路、地铁和轻轨通道的咽喉区段,地下一层为行李传送通道、机电管廊系统和预留的APM捷运通道,地上一层至五层为进港、出港、票务、安检、行李提取等功能区。

相关负责人介绍说,新机场航站楼是目前全球最大的全现浇钢筋混凝土框架结构单体机场航站楼,具有工程规模大、造型新颖、功能先进、系统复杂、多标段同步施工等特点和难点。

主航站楼的金属屋面最高点50米,向周边起伏下降至指廊端部25米,楼前屋盖悬挑长度达47米。

此外,新机场航站楼首次有高速铁路在地下穿过,首次采用双层出发双层到达设计,按照8度抗震设防要求。核心区、指廊和综合服务楼及停车楼将同步施工。

3条轨道交通穿越航站楼

而北京建工集团中标的则是航站楼的另一大部分——“北京新机场旅客航站楼及综合换乘中心(指廊)工程”,即航站楼东北、东南、中南、西南、西北的五座指廊。总面积30万平方米,总造价32.7亿元。

据介绍,这种放射状的结构和布局将在最小化旅客转机、接驳交通距离的同时增强整个航站楼的连通性。届时旅客仅需步行8分钟就可以抵达新机场的最远端登机口。

建工集团表示,为确保2019年建成通航,五座指廊将同时建设。其中,西南、中南、东南三条指廊各长411米,西北、东北两条各长298米。五座指廊总长度达1829米,单体面积在4.6万到10万平米之间。并且,京霸铁路、新机场线、R4线三条规划轨道线将并行穿越中南指廊。

■ 新机场

●新机场位于永定河北岸,北京大兴区礼贤镇、榆垡镇和河北廊坊市广阳区之间,北距天安门46公里,西距京九铁路4.3公里,南距永定河北岸大堤1公里,与位于顺义区的首都国际机场相距68公里。

●一期总用地面积3031.9公顷,按2025年客流量7200万人次、货邮吞吐量200万吨、飞机起降量62万架次的目标设计,建设4条跑道,80万平方米航站楼、40万平方米的停车楼及综合服务楼、5.2万平方米的双层高架桥及相应的货运、空管等生产生活设施。
