1 Project Overview Pingdingshan Qixing to Yao Electric Company Belt Coal Transportation Tunnel Interval mileage DK0 +874.170 ~ DK2 +277,000 (full length 1402.83m meter 934 ring), of which the first 100m for the starting section. The shield tunneling method is adopted. The outer diameter of the tunnel is 6000mm, the inner diameter is 5400mm, the width of the lining block is 1500mm, the thickness is 300mm, the design strength of the lining concrete is C50 and the anti-seepage intensity is P10; It consists of a top block, two adjacent blocks, two standard blocks and an arch bottom block. Pingdingshan Qixing to Yao Electric Company Belt Coal Conveyor Project in the shield construction to go under the Meng Bao railway, Nan Luo Expressway, Pingdingshan Road Construction Road and Zhanhe and other important construction
