Powered by COVER STORY interaction What are the opportunities you are Please share with us a Case Study of one of your metro rail projects, the challenges faced seeking in the metro space going forward? and how you overcame them. Tell us of the metro projects in which you On March 12, CRCHI slurry/earth pressure balanced shield machine launched at the northern extension are looking to contribute? of Line 8 of Guangzhou Rail Transit. India is just like the Chinese market, Continuous and safe advance of SPB machine is realized by the balance between the mudpack tension both countries have a large number of and pressure from earth and water on the excavation face. Compared with that of EPB machine, the population and have developed quickly, slurry control process of SPB is more stable and the the control performance is more concise. So SPB however infrastructure needs to be machine is especially suitable for most large tunnel projects which go through rivers and lakes and have improved to meet the daily requirement high demand for excavation face stability with high water content and strong permeable layer. of people’s transportation. Hence, As the complicated engineering hydrology of this project, the shield machine needs to go through long metro as one part of three - dimensional distance of high-viscosity silty clay, silty sand with high permeability, medium-coarse sand, full-section transportation network is very popular in moderate weathered limestone and upper-sof lower-hard formations. Te machine also may meet India; CRCHI, which is one of the pioneer boulders or karst caves on the way and some unpredicted situation happened on the ground. of underground equipment manufacturers Considering these situations, CRCHI combined slurry balance mode and earth balance mode and in the world, would like to contribute its developed the dual-mode shield machine which has the technical features of both EPB and SPB to better advanced technology and machinery in the control excavation face pressure and to keep the ground stable while ensuring tunneling efciency. In construction of Indian Metro System. silty clay layer the shield machine switches to EPB mode while in sand layer it switches to SPB mode. Give us an understanding of your TBM with fully self-intellectual property market opportunities and your strategy manufacturing facilities, locations, their right has been worked in the railway projects to tap those going forward? capacities to support various metro rail of Changsha, Beijing, Xi’an, Wuhan, Currently, many cities in India are planning projects? Guangzhou, Suzhou, Nanjing, and Fuzhou, or already started to build metro lines, CRCHI has established many manufacturing self-developed mining tunnel machinery like Delhi, Chennai, Kolkata, Mumbai, bases in Changsha, Zhuzhou, Longchang with world’s leading level has been worked Lucknow and so on, which means the local and Lanzhou, with 11 research institutes at high speed railway construction site of Governments are giving lots of importance in Changsha, Beijing and Lanzhou, the Shanghai-Kunming line and Chengdu- to the construction of metro projects. technology centre has more than 600 Chongqing line. CRCHI has world’s most CRCHI are willing to work together with research personnel. CRCHI has 5200 advanced turnout, rail fastener production local organisation or company to develop the employees, among 74 senior title employees, line, the products are widely used in high- metro projects and bring our best products 324 medium title employees, 539 junior title speed railway, such as Beijing-Shanghai, and service at a competitive price. employees and 1647 technicians, we also Wuhan-Guangzhou high speed railways. have 5000t pressure machine with world’s CRCHI Turnout Company is a newly Future outlook for the industry and from leading level and related devices. CRCHI is professional turnout manufacturing plant a company perspective. the only one professional enterprise which with CNY 500,000,000.00 ($73, 000,000) Te frst step of CRCHI is selling the frst owns development capability of both shield investment capital which was established on unit of TBM in Indian Market and building and mining method tunnel equipment, the basis of railway construction requirement its good reputation, then we will set up the and also has the shield/TBM professional of domestic passenger dedicated line, and its Indian Sub-company in Mumbai /Delhi production line with world biggest annual design and production capability of and gradually we will start the assembly production capacity, complete equipment turnout is 5000 sets. line in India. Te company’s perspective is and the most advanced technology all over to achieve the CRCHI TBMs brand with the world.
