On September 24, Mr. He Qinghua, Chairman of Shanhe Intelligence and Chief Expert, and his delegation investigated the Dongguan project of China Railway Shanhe, inspected the construction progress of the project on the spot, and put forward the requirements for the project as well as the high-quality development of China Railway Shanhe. Tang Biao, deputy general manager of Shanhe Intelligence and chairman of CRSR, Ding Qu, general manager of Huaan Foundation, and Deng Zhanhua, deputy general manager of CRSR, accompanied the research.

    He Qinghua and his team first went to the construction site of the Dongguan project for a site visit to understand the construction equipment, environment and progress. “You should continue to play the spirit of hard struggle to ensure that the project is completed on time and in quality and safety; you should make more suggestions to understand the direction of equipment improvement through construction; and you should promote lean production to reduce the number of employees as well as the intensity of work.” At the site, He Qinghua expressed his thanks and affirmation to the employees who fought on the front line under the high temperature, and put forward several requirements.

Afterwards, at the forum, He Qinghua listened to the report on the organizational structure, personnel composition and specific construction progress of Dongguan project. He affirmed the brand promotion and talent team construction of China Railway Shanhe, and emphasized that China Railway Shanhe should make use of the brand effect, give full play to the advantages of “equipment+work method+construction”, strengthen the interaction and coordination, expand as soon as possible, and continue to grow bigger and stronger to achieve safe, efficient and high-quality development.

     It is understood that China Railway Shanhe Dongguan Metro Line 1 1301-3 double line is 4600 meters long, divided into two starts, Daojiao East Station ~ People's Hospital Station interval, shield section line length of 589m, put 31, 32 two shield machine, from the big mileage to the direction of the small mileage tunnelling to 29 ‰ uphill to receive the plane of the smallest turning radius of 500m, the tunnel range has a complex and varied geology, depth of burial The tunnel range is characterized by complex and varied geology, large height difference, and many types of buildings along the route, which brings many challenges to the equipment construction. As of mid-September, Dao Ren (Daojiao East Station ~ People's Hospital) interval right tunnel has been through, was rated as the best performance of the section, the left shield is operating, is expected to be through at the end of October.

     At present, the shield machine of Shanhe Intelligent can be seen in many underground space construction projects. In the construction project of Longquan inverted siphon tunnel of Dianzhong Water Diversion Project, the shield tunnelling distance reaches 5 kilometers in a single pass; in the first shield method power pipeline corridor construction project in Changsha, the tunnel exists a number of small radius continuous turns of 150m, which makes the construction difficult....... All these are hard to resist the Shanhe Intelligent Shield Tunnelling Machine. Based on strict site management and quality management, Shanhe Intelligent shield machine in Guangzhou, Shenzhen, Chengdu, Changsha, Kunming and other cities in the subway, pipeline corridor construction demonstrated a low failure rate.

Next, Shanhe Intelligence will further strengthen the innovation of equipment and work method as well as the overall planning of the construction section to play a more important role in the field of underground space construction.
