China Construction Machinery Information

Guide: improving the energy utilization efficiency of the plastic granulator process and preventing and controlling environmental pollution are complementary. On May 11, Chuncheng No.7 shield machine started from the exhibition center station and drove towards Kunming railway station, It is expected to run through the section from Kunming railway station to exhibition center station in September. At the platform level 17 meters below the exhibition center station, two shield machines have been assembled and debugged. Chuncheng No. 7 shield machine is moving forward

on May 11, Chuncheng No.7 shield machine started from the exhibition center station, heading towards Kunming railway station. It is expected to run through the section from Kunming railway station to the exhibition center station in September

at the platform layer 17 meters deep underground of the exhibition center station, two shield machines have been assembled, which can continue the concept of our taxi catamaran. "Complete installation - it is said that the commissioning of Muhammad peharda has been completed, and the Chuncheng No. 7 shield machine is heading forward. The workers are nervous about installing the tunnel ring, and the operator gently presses several buttons to install the ring weighing hundreds of tons in place. According to the technicians, since the shield was just started, the mechanical equipment was still in the running in state. In order to ensure safety, only 6 or 7 meters could be excavated every day

considering the geology and landform of the line, the construction party spent 94million yuan to purchase two new EPB shield machines from Germany to deal with the underground composite soil. Yangzhengzheng, the project manager, introduced that the Chuncheng No. 7 shield is in the right line section. By the end of this month, it will drive about 90 meters, which leaves enough safety distance for the left line shield. By the end of this month, the left line shield will also start

according to the data, the shield interval from the exhibition center station to Kunming railway station is 921m long. The shield machine starts from the north end of the exhibition center station, goes north along Chuncheng Road, turns Northwest after leaving the international trade interchange, goes to Fuda Road, and arrives at Kunming railway station along Fuyong road. The construction difficulties are mainly that the shield line crosses Guomao Road Interchange, the production workshop of Kunming Power Supply Industry Corporation and Fude village

according to the introduction, the Guomao Road Interchange originally had two pile foundations located on the shield line. Later, the pile foundations were replaced. After the original pile foundations were broken, two new piers were constructed on both sides of the road. A project team column was established as early as one year ago to ensure the safety of the interchange and enable the shield line to pass through the interchange smoothly. When passing through Fude village, it is planned to temporarily move the residents of the houses within the affected area. What is more serious on the ground is that if these dust enters the hydraulic system of the electro-hydraulic servo universal testing machine for reinforcement, the impact of the construction on the ground buildings will be reduced. The construction unit is stepping up the formulation of emergency plans and strengthening monitoring
