C114讯 9月14日消息（张海龙 孙小玉）日前，长春地铁2号线正式通车。在通车的同时，三大运营商的网络信号便实现了全覆盖，让乘客可以在乘坐地铁的时候可以随时上网打电话。这背后是吉林铁塔不懈的努力。

尤其值得一提的是，吉林铁塔还在长春地铁2号线实现了业界首次地铁内场景的广角漏缆技术创新应用，并通过共享为行业节约投资3000万，而且这些成绩还是在工期仅为180天情况下实现的。

为行业节约投资3000万

2014年10月，吉林铁塔成立后，为有效推进地铁线路的网络共建共享，公司成立了地铁项目组，多次向长春市政府汇报，得到了政府层面的支持，把移动通信基础设施建设，尤其是与老百姓息息相关的地铁内的网络基础设施建设作为惠民工程来抓。由吉林铁塔牵头统筹三家运营商需求，与地铁公司进行对接、协调，实现了同步规划、同步设计、同步施工、同步开通。

2017年6月30日，圆满完成了地铁长春1号线民用通信工程建设任务。吉林铁塔在长春地铁2号线民用通信工程建设过程中，通过统筹集约，总投资约1690万元，单公里造价仅为约73万元。对比三家运营商分别建设模式，铁塔公司的共享模式为轨道交通集团共计节省机房面积约758平方米，减少装修吊顶破坏面积约2054平方米，减少区间设备布放面积约3065平方米，为通信行业共计节省了约3200万元建设投资。

建成国内首例无天线地铁站

长春地铁2号线拥有国内首创的装配式车站，这种节省工期又节能环保的装配式车站拥有很多传统车站无法比拟的优点，但对于民用通信工程的施工却带来了前所未有的难题。由于装配式车站棚顶无法布放任何线缆，也不能对墙体打孔，传统的吸顶天线安装无法实现。但吉林铁塔没在困难前止步，而是以创新为指引，攻克了一个又一个难题，向社会展示了铁塔公司作为信息通信基础设施建设主力军的担当和作为。

吉林铁塔长春地铁通信工程建设项目组通过与广东省电信规划设计院有限公司、中天射频电缆有限公司、华为技术服务有限公司、武汉虹信通信技术有限责任公司和广东公诚通信建设监理有限公司等合作单位的反复论证，决定在5个装配式车站，采用新型的广角漏缆替代传统的"吸顶天线+馈线+无源器件"模式。这种创新模式不但节约了建设成本，还使得区域内的信号覆盖更加均匀，将广角漏缆应用于地铁场景信号覆盖在全国尚属首次。

在技术创新的同时，工程管理上也进行了突破。为提高效率，确保质量，项目组针对长春地铁2号线项目特点，在合作伙伴的ISDP平台上开发出相应的项目管理模块，每天把各个站的施工情况更新到平台上，平台自动把数据转化成图表形式，施工进度情况一目了然。现场督导通过手机拍摄现场施工工艺的照片上传到平台，管理人员从后台便可查看各施工场景的施工质量。

C114 news September 14th (Zhang Hailong Sun Xiaoyu) recently, Changchun Metro Line 2 was officially opened to traffic. At the same time, the three operators have achieved full coverage of network signals, allowing passengers to take the subway when they can call the Internet at any time. Behind this is the unremitting efforts of the Jilin iron tower.

Especially, Jilin Tower realized the first wide-angle cable leakage technology innovation application in Changchun Metro Line 2, and saved investment of 30 million yuan through sharing. These achievements were achieved in 180 days.

Save investment for the industry 30 million

In October 2014, after the establishment of the Jilin Tower, in order to effectively promote the co-construction and sharing of subway lines, the company established a subway project team, reported to the Changchun Municipal Government many times, and received support from the government at the level of mobile communication infrastructure construction, especially in the subway network infrastructure construction closely related to the people. As a project to benefit the people. Jilin Iron Tower takes the lead in co-ordinating the needs of the three operators, connecting and coordinating with the subway company, realizing synchronous planning, synchronous design, synchronous construction and synchronous opening.

In June 30, 2017, the civil communication project construction of Changchun Metro Line 1 was successfully completed. During the construction of the civil communication project of Changchun Metro Line 2, the Jilin Tower invested about 16.9 million yuan and the cost per kilometer was only about 730,000 yuan. Comparing with the three operators'respective construction modes, the sharing mode of the tower company saves about 758 square meters of room area, 2054 square meters of damaged ceiling area, 3065 square meters of equipment area, and saves about 32 million yuan of construction investment for the communications industry.

Built the first subway station without antenna in China

Changchun Metro Line 2 has the first assembled station in China. This kind of assembled station has many advantages which can not be compared with traditional stations, but it brings unprecedented difficulties to the construction of civil communication projects. The traditional roof antenna installation can not be realized because the roof of the assembled station can not lay any cables or perforate the wall. However, instead of stopping before difficulties, the Jilin Iron Tower, guided by innovation, has overcome one difficult problem after another, and has shown the society that the Iron Tower Company acts as the main force in the construction of information and communication infrastructure.

Through repeated demonstrations with Guangdong Telecom Planning and Design Institute Limited, Zhongtian Radio Frequency Cable Limited, Huawei Technical Services Limited, Wuhan Hongxin Communication Technology Co., Ltd. and Guangdong Gongcheng Communication Construction Supervision Co., Ltd., the construction project team of Changchun Metro of Jilin Iron Tower has decided. In 5 assembly stations, a new wide-angle leaky cable was used to replace the traditional "ceiling antenna + feeder + passive device" mode. This innovative mode not only saves the construction cost, but also makes the signal coverage in the region more uniform. It is the first time that wide-angle leakage cable is applied to subway scene signal coverage in China.

At the same time of technological innovation, engineering management has also made breakthroughs. In order to improve efficiency and ensure quality, according to the characteristics of Changchun Metro Line 2 project, the project team develops the corresponding project management module on the partner's ISDP platform. Every day, the construction situation of each station is updated to the platform. The platform automatically converts the data into chart form, and the construction progress is clear at a glance. The site supervisor uploads the photos of the site construction technology to the platform through the mobile phone, and the managers can view the construction quality of each construction scene from the background.
