Alkali-Ispartakule High-speed Railway Project is a high-speed railway project connecting Halkali Station and Sychkoy District. Its shield tunneling section is divided into left and right tunneling sections. The tunneling mileage of single equipment is about 6 kilometers, and the maximum buried depth of the section is 55 meters. The geology of the tunnel is dominated by clay, silty sand, sandstone, conglomerate, claystone, and marlstone, and the tunnel passes through lakes and the proposed canal.
The project will use two earth pressure balance shield machines with a diameter of 8.54 meters independently developed by China Railway Hi-Tech Industry. Because of the complex geological characteristics of the project, such as large buried depth and high water pressure, as well as the special needs of customers, the shield development team made an in-depth analysis and precise grasp, tailored the whole machine plan, and created exclusive equipment for customers. The "CREC 1149" shield machine used in the project will also be launched soon.
