[Shantou Bay Tunnel Ludao No. shield machine off the production line] On February 21, 2023, a Tunjima shield machine with the pattern of a brave tiger shark painted on the cutter head was completed and rolled off the production line smoothly. This is a domestically produced large-diameter mud-water balance shield machine jointly built by China Railway 14th Bureau and China Railway Construction Heavy Industry Group. It will be used in the construction of the Shantou Bay Tunnel on the Shantou Guang'ao Port Area Railway, and will soon start a journey through the sea. Shantou Guangao Port Railway is located in Shantou City, Guangdong Province. It starts from Shantou Station of Guangmeishan Railway in the north and ends at Guangao Port in the south. The Guangzhou-Macao Port Area Railway Line 1 has a total length of 17.116 kilometers, including a tunnel, two bridges and other construction content. The Shantou Bay Tunnel is a key and difficult control project of the project, with a total length of 9965 meters, of which the shield section is 2990 meters long. The segment has an outer diameter of 12.9 meters and an inner diameter of 11.8 meters. The excavation diameter of the cutter head of the Tunnel Tunneling Machine on the Gudao Island is 13.42 meters, the total length of the shield machine is 126 meters, the weight of the whole machine is about 3,300 tons, and the total installed power is 9,300 kilowatts. The shield cutter head has the functions of normal pressure tool change, hob exchange, hob wear detection, speed detection, and temperature detection. In order to deal with the problem of low construction efficiency in hard rock formations, the distance between cutterheads and cutters of the shield machine has been further reduced, and pressure hobs have been added to help improve rock breaking efficiency. The cutter head is equipped with a total of 185 cutters, of which 89 can be replaced under normal pressure, realizing full coverage of the cutter head's excavation trajectory. Editor / Zhao E

• [China's battery factory will land in Thailand, with an investment of 30 billion]
• The Board of Investment Promotion of Thailand (BOI) revealed that Seven world-leading Chinese battery manufacturers, including Ningde Times New Energy Technology Co., LTD., AVIC Lithium Technology Co., LTD., Inbai Battery Technology Co., LTD., Yiwei Lithium Energy Co., LTD., Guoxun High-tech Power Energy Co., LTD., Xinwangda Electronics Co., LTD., and Beehive Energy Technology Co., LTD., have chosen Thailand as their battery production base The development prospect of... BOI predicts that in 2024, at least two battery manufacturers from China will invest in the production of batteries in Thailand, and the first phase of investment will exceed 30 billion baht. In order to attract more battery manufacturers to invest in Thailand to set up production bases, BOI and relevant departments will introduce a series of policy measures, such as exempting investors from corporate income tax, exempting machinery and raw material import duties, etc., while relevant departments will also provide certain financial support, improve the relevant infrastructure construction, and train high-level researchers in related fields. With the continuous presence of battery manufacturers, it will help improve the supply chain of Thailand's electric vehicle industry and achieve energy renewable. Editor/Xu Shengpeng

• [The second phase of the China-Thailand Railway was submitted for deliberation]
• National Railway Authority of Thailand (SRT) Director Neelu revealed that on the 18th of this month, the board of directors of the Railway Bureau met to review the second phase of the China-Thailand government high-speed railway project: Korat - Nong Khai section cooperation project, the project length of 357.12 kilometers, the budget of 341.351 billion baht. It is divided into 235.129 billion baht for civil works of the high-speed rail project, 10.31 billion baht for land ownership and property compensation, 80.165 billion baht for investment in the railway system-electric train system and machinery, and 10.06 billion baht for project management consultancy and supervision work and system certification. At present, the detailed design of the project has been completed and the environmental impact assessment report is in progress. Meanwhile, the second phase of the China-Thailand high-speed railway project will be tendering in the form of an E-Bidding system in 2025, with a total of 13 project contracts, which are expected to be completed in 2030 and put into use in 2031. In addition, the project has also adjusted the civil works, divided into 202.48 km of elevated track and 154.64 km of surface track, aiming to avoid impact on the five large stations in the relevant area.
