毗邻“鸟巢”“水立方” “冰丝带”打造又一标志性奥运场馆

北京已入隆冬，在北五环国家网球中心钻石球场南侧，国家速滑馆建设工地上依旧如火如荼，一些曾参加过2008年北京奥运会施工的建设者再续奥运情缘。而这座有个浪漫名字“冰丝带”的2022年北京冬奥会新建场馆，无疑将为北京奥运遗产再添亮点。

国家速滑馆的设计理念为冰的象征，灵感来源于速滑选手围绕场地进行比赛，体现出冰上比赛的激烈竞争；运动员滑行的轨迹被诠释为外立面的22条丝带，而这22条丝带又代表着北京承办冬奥会的年份。速滑馆作为北京冬奥会的主要运动场馆，其所代表的“冰”属性，与坐落于奥林匹克公园内象征水的“水立方”和象征火的“鸟巢”交相辉映。

据施工方介绍，“冰丝带”目前已完成土护降工程，即将进入基础桩和主体结构施工阶段。该场馆土方量超过50万立方米，挖槽面比“鸟巢”还大，预计2019年底完工，2020年进行测试赛。

记者看到，“冰丝带”施工秩序井然，现场还对PM2.5、噪声、风力、风速、风向、温度、湿度等进行实时监测。施工同时，也对工地内存在的清代文物兆惠墓碑进行了保护。土方工程每天在现场约有350名施工人员，如果算上挖土司机则要超过500人，其中包括许多曾经参加过2008年北京奥运会施工的建设者。

本次土方工程的负责人、59岁的赵俊德，曾担任2008年奥运会媒体村施工项目经理。他说自己非常荣幸，能够在职业生涯中经历两届奥运施工很难得。54岁的陈平权是“冰丝带”的总监理工程师，他参加了2008年奥运会自行车馆建设，“两个奥运我们都参与了，很光荣，也感到责任重大，我们一定努力建设‘冰丝带’，力争国家鲁班奖”。28岁的工人邓敏来自四川成都，是这里的木工。他说能够参与冬奥工程很开心，希望在2022年能再次回到这里观看比赛。

据北京市国有资产经营有限责任公司副总经理、国家速滑馆项目负责人武晓南介绍，国家速滑馆“冰丝带”有四大亮点。首先，“冰丝带”建设面临的首要难点是其长200米、宽130米的大跨度屋顶，而且不同于一般建筑，速滑馆的屋顶为不规则马鞍形，更是增加了建设难度。为了解决这个难题，国家速滑馆将被建设成为国内最大跨度的单层索网屋顶体育馆。不仅如此，索网结构更是符合绿色办奥的要求，一是其用钢量约为传统屋顶的1/4；二是工厂定制、现场装配、施工简便、污染小。

其次，“冰丝带”采用全冰面设计，面积约1.2万平方米，近似一个田径场大小，是亚洲冰面最大的速滑馆。通过冰面的分区控制，不仅可满足速度滑冰、短道速滑、花样滑冰、冰壶、冰球等五大类冰上运动项目的竞赛要求，还可以成为冰雪运动全民健身中心。

第三，速滑馆1.2万平方米的冰面将产生大量制冰余热，回收后可用于运动员生活热水、融冰池融冰、冰面维护浇冰，每年能够节省180万度用电量。

第四，“冰丝带”还将被打造成智慧场馆，体现在全方位运动数据服务、智能化观赛服务、智慧化场馆管理三个方面。全方位运动数据主要包括为运动员提供计时、计速和计圈的训练服务；智慧化观赛服务包括智能座位导引、实时赛事解析、座位上购物订餐等；智能化场馆管理包括智能物业管控、智能场地管理、智能场馆运营等。

这座有着浪漫名字的场馆，将成为北京又一座标志性的奥运建筑。2022年冬奥会后，这里将成为全民健身场所，并将继续举办高水平的冰雪赛事。据悉，未来的国家速滑馆将聚焦以下几个方面：以冰雪为中心的体育竞赛，以冰雪为特色的群众体育健身，以冰雪产业为核心的会展，以及体育公益，成为集体育赛事、群众健身、文化休闲、展览展示、社会公益于一体的多功能冰雪中心。

Adjacent to "bird's nest" "Water Cube" "ice ribbon" to create another landmark Olympic Stadium

Beijing has entered the middle of winter. In the south side of the North Fifth Ring National Tennis Center Diamond court, the construction site of the national speed skating hall is still in full swing. Some of the builders who participated in the 2008 Beijing Olympic Games continue Olympic Games. The new stadium, which has a romantic name "ice ribbon" in the 2022 Beijing Olympic Games, will undoubtedly add a bright spot to the Beijing Olympic heritage.

The design idea of the country for ice skating hall symbol, inspired by the skaters around the site of the game reflects the fierce competition on ice contest; athletes taxiing trajectory was interpreted as 22 ribbons of the facade and the 22 ribbon and represent Beijing to host the Winter Olympics of the year. As the main stadium of Beijing Winter Olympic Games, the ice skating property represents the "Water Cube" that represents the water in the Olympic Park and the "bird's nest" symbolizing fire.

According to the construction party, the "ice ribbon" has already completed the soil protection project, and will enter the construction stage of the foundation pile and the main structure. The venue of the earthwork of more than 500 thousand cubic meters, chamfer surface is larger than the "bird's nest", is expected to be completed by the end of 2019, the 2020 test matches.

The reporter saw that the "ice ribbon" construction is orderly, the scene also PM2.5, noise, wind, wind speed, wind direction, temperature, humidity and other real-time monitoring. At the same time, the tomb monument in the Qing Dynasty was protected in the construction site. There are about 350 construction workers in the field every day, if the number of drivers is more than 500, including many builders who once participated in the construction of Beijing Olympic Games in 2008.

The 59 year old Zhao Junde, head of the earthwork project, was the manager of the construction project of the media village of the 2008 Olympic Games. He said he was very honored to be able to experience the two Olympic Games in his career. Chen Pingquan, 54 years old, is the chief supervision engineer of "ice ribbon". He participated in the construction of the bicycle Hall of 2008 Olympic Games. We participated in the two Olympic Games. We felt honored and felt great responsibility. We must strive to build "ice ribbon" and strive for the national Luban prize. Deng Min, a 28 year old worker from Chengdu, Sichuan, is a carpenter. He said he was happy to participate in the Winter Olympics and hoped to be back here again in 2022 to watch the game.

According to Wu Xiaonan, deputy general manager of Beijing state owned assets management limited liability company and the national speed skating hall project leader, there are four highlights in the national speed skating hall "ice ribbon". First of all, the main difficulty facing the construction of "ice ribbon" is the long span roof which is 200 meters long and 130 meters wide, and is different from the general buildings. The roof of the speed skating hall is irregular saddle shape, which is also increasing the difficulty of construction. In order to solve this problem, the national speed skating hall will be built into the largest single layer cable net roof gymnasium in China. Moreover, the cable net structure is more consistent with the requirements of Green Olympics. First, the steel volume is about 1/4 of the traditional roof. The two is factory customization, on-site assembly, simple construction and low pollution.

Second, the "ice ribbon" is designed with an ice surface with an area of about 12 thousand square meters. It is the size of a track and field field. It is the largest speed skating hall in the Asian ice. Through the zoning control of ice, it can not only meet the competition requirements of five categories of ice sports such as speed skating, short track speed skating, figure skating, curling, ice hockey, but also become the National Fitness Center for ice and snow sports.

Third, speed skating Hall of 12 thousand square meters of ice ice will produce large amounts of waste heat, which can be recycled for athletes to hot water and ice melting pool melting ice, ice maintenance pouring ice, can save 1 million 800 thousand of electricity per year.

Fourth, the "ice ribbon" will also be built into wisdom venues, embodied in the three aspects of motion data services and intelligent services, intelligent facility management programme. The full range of motion data mainly includes the timing, speed and circle for the training of athletes; intelligent service spectators including intelligent guidance, real-time event analysis, seat seat reservation and other shopping venues; intelligent management including intelligent control, intelligent property management, intelligent operation and other venues venue.

This stadium, with a romantic name, will be another landmark in Beijing. After the Winter Olympics in 2022, it will become a national fitness site and will continue to hold a high level of ice and snow events. It is reported that the future of the national speed skating hall will focus on the following aspects: snow and ice as the center of the sports competition, the ice for the characteristics of mass sports, the ice industry as the core of the exhibition, and the sports public service, become a set of sports, fitness, culture and leisure, exhibition display, social welfare center in one of the snow multi function.
