The city's fast track is experiencing explosive development of the abrasives industry with new opportunities
With the suburbanization of large cities and the construction of metropolitan areas, the city's fast track, which is the basis of transportation, is experiencing explosive development.
First, the city's fast track ushered in an outbreak
According to local media reports in Zhejiang, the relevant report of the Hangzhou-Xincheng Intercity Railway officially renamed “Hangzhou Metro Line 16†has been reported and is currently awaiting approval.
According to the data, the Hanglin Intercity Railway started construction in 2015 with a total length of 34.98 kilometers, a design speed of 100 km/h, 12 stations, and an average station spacing of 3.13 km. It is expected to open in 2019. After opening to traffic, it is estimated that it will take about half an hour to arrive from the Linan City to the Future Technology City. After the Hangzhou Intercity Railway is fully put into use, it will greatly promote the comprehensive Hangzhou-Hangzhou process.
The name change of Hanglin Intercity also means that the line will be incorporated into urban rail transit management. In fact, from the point of view of design speed, station spacing and other indicators, Hanglin Intercity is a typical city fast track line, which is included in the urban rail transit management, and is also conducive to strengthening the connection between the main urban area of ​​Hangzhou and the remote suburbs and satellite cities.
The city's fast track is also called the city railway, the city express line, etc., mainly serving cities and suburbs, central cities and satellite cities, key towns, etc. The service scope is generally within 100 kilometers, which is between urban rail transit (metro, light rail). A new mode of transportation between the city and the intercity high-speed railway.
Hu Gang, president of the South China Urban Research Association and professor of Jinan University, analyzed that the speed of the subway is relatively slow, mainly serving the internal traffic of the main city, while the speed of the city's fast track is relatively fast, the service is the peripheral area, and the peripheral area can be The surrounding satellite city is closely connected to the main city.
In fact, not only Hangzhou, but also the city's fast track in other cities in China is accelerating.
For example, Zhengzhou Rail Transit Vision Annual Line Network consists of 21 lines with a total length of 970.9 kilometers, including 13 lines of 505 kilometers for metro lines and 466 kilometers for 8 lines of city express lines. The city's fast track planning mileage accounts for nearly half of the total mileage.
In Nanjing, the city's current urban rail transit mileage is 394 kilometers, of which the city's fast track mileage has reached 200.8 kilometers.
According to the research report of Tianfeng Securities Research Institute, the total length of China's urban fast-track operation lines is still low, accounting for a small proportion of urban rail transit lines, but the growth is strong.
According to the 2018 Statistical Analysis Report of Urban Rail Transit issued by the China Urban Rail Transit Association, by the end of 2018, there were 185 urban rail transit lines in 35 cities in China, with a total operating length of 5761.4 kilometers, including the city's fast track. 656.5 kilometers, accounting for 11.4% of the total length of the line, second only to the subway line.
Among them, in 2018, the city's new fast track line was 154.5 kilometers, an increase of 72.1%, leading the growth rate in various standard lines. In addition, the city's fast track is under construction of 575.2 kilometers, and is expected to be completed and put into operation within the next two years. The potential growth scale is relatively large.
According to the report, there are currently 24 urban expressway lines in the north, including Guangzhou, Shenzhen and Shenzhen, which are in operation or have related project construction plans. A total of 69 lines in 24 cities are under construction and pending construction, 2019 In the following years, the number of express trains to be built in the next year will reach 2,370 kilometers, which is 3.61 times of the mileage (656.5 kilometers) completed by the end of 2018; during the period of 2019~2021, the investment amount of the domestic fast track will reach 735.423 billion.
A considerable scale of investment and construction will bring many development opportunities for enterprises engaged in rail transit-related businesses. The demand for grinding wheels, knives and other products is huge for the complete sets of processing equipment for rail transit equipment. For example, in the braking and buffering system of fast-track trains, the spring is an indispensable mechanical basic part. The spring passes through the process of winding spring, heat treatment, etc., the section needs to be ground, and the amount of spring consumed by the railway system is thousands on each year. More than 10,000 tons; large-scale atmospheric hole grinding wheels for grinding railway springs increase by 30% every year; in addition, in the case of rapid development of fast-track trains, the special grinding wheels for rail grinding vehicles are bound to increase significantly.
Second, to meet the development needs of the metropolitan area
The rapid development of the city's fast track conforms to the development trend of the metropolitan suburbanization and the creation of the metropolitan area in recent years.
In recent years, the development of first- and second-tier cities has shown an obvious suburbanization trend. For example, data from the Hangzhou Municipal Bureau of Statistics show that in 2017, the resident population of the old city (Shangcheng District, Xiacheng District, Jianggan District, Gongshu District, Xihu District, and Mingsheng District) was 3.073 million, an increase of only 0.5%, far lower than the city; The surrounding areas (Binjiang District, Economic Development Zone, Dajiangdong, Xiaoshan District, Yuhang District, Fuyang District, Lin'an District) have a resident population of 5.168 million, an increase of 5.2%, which is the main area for the growth of permanent residents in Hangzhou.
According to the research report of Huaxia Happiness Industry Research Institute, from 2001 to now, the population growth rate in Beijing has slowed down and even tended to stagnate. The population of the surrounding districts and counties has accelerated, and the growth rate has increased to 4%. The outer ring layer has appeared Guangyang and Guji. An is a node city that plays a key supporting role in the development of the hinterland of Beijing.
The population of the Yangtze River Delta region is clustered with Shanghai and Hangzhou as the core. The population of the Shanghai metropolitan area has increased by 640,000 between 2010 and 2017. In the same period, the population of the outer circle is nearly twice that of the urban nuclear increment. 1.25 million people, Kunshan, Jiangyin and other node cities have a population of more than 1.5 million.
The Pearl River Delta region also exhibits the characteristics of accelerated population spillovers. The population is widely distributed between Guangzhou and Shenzhen. The surrounding Dongguan and Zhongshan are all millions of population-level cities.
Peng Yu, vice president of the Guangdong Reform Research Association, analyzed the first financial analysis. The suburbanization of big cities is driven by housing prices. The housing prices in the central area are too expensive. Young people will go to the suburbs when considering the price/performance ratio. In addition, many suburbs have state-level development zones, and a large number of high-tech industries will attract a lot of young people.
With the suburbanization of the population, the connections between big cities, central cities and surrounding areas, and satellite cities have become closer and closer, and a metropolitan circle has been formed, which has led to the development of regional economy. The National Development and Reform Commission issued the "Guiding Opinions on Cultivating the Development of Modern Metropolitan Areas" (hereinafter referred to as "Opinions"), which proposed that by 2022, China's metropolitan area will achieve significant progress; by 2035, the modern metropolitan pattern will become more mature. To form a number of metropolitan areas with global influence.
According to the China Metropolitan Development Report 2018 jointly published by Tsinghua University China New Urbanization Research Institute and Beijing Tsinghua Tongheng Planning and Design Institute, there are currently 34 central city metropolitan areas in the country, including 8 metropolitan areas in 3 regions. The scope has overlapped and developed in succession, forming a continuous urban area, and the remaining 26 are relatively independent urban circles. The total area of ​​the above-mentioned metropolitan area is about 2.324 million square kilometers, accounting for 24% of the national total; the total population is about 81.59 million, accounting for 59% of the national total, and the regional GDP accounts for 77.8% of the national total.
To build a modern metropolitan area, it is inseparable from the development of rail transit, especially in the urban fast track. Only by vigorously building the city's fast track can we promote the distribution of population and industry to surrounding areas and satellite cities, and dispel the non-core functions of the main urban area.
The aforementioned "Opinions" proposes that the metropolitan area (suburb) railway should be vigorously developed, and the existing railways should be used to revitalize the city (suburb) trains by means of existing railway reinforcement, local line reconstruction and reconstruction, and station platform reconstruction. New urban (suburban) railways will be incorporated into the urban public transportation system. Explore the “one network†of metropolitan rail transit operation management, and promote the effective connection of rail transits such as central cities, surrounding cities (towns) and new urban new districts, speed up the realization of convenient transfer and better adapt to commuting needs.
Hu Gang believes that the metro network in the central city of Beishangguang and other big cities has gradually improved, and the focus of these cities will spread from the central city to the surrounding areas in the future. Therefore, connecting the central area with the suburbs and satellite city's urban fast track will become the focus of development.
