Tianjiazhai Tunnel is one of the key and difficult projects along the Shenwa Railway. The geological conditions of the tunnel are extremely complex, requiring crossing horizontal rock layers with poor stability of the surrounding rock. The construction difficulty is high and the technical requirements are high. To ensure smooth entry into the tunnel, the project department of China Railway Construction 23rd Bureau Group Co., Ltd. fully utilized its technical and management advantages, planned and scientifically organized in advance, conducted detailed geological surveys around the tunnel during the construction preparation stage, and formulated targeted construction plans. Faced with complex geological challenges, the project team adopts advanced geological forecasting technology to dynamically grasp changes in the rock layers ahead and optimize construction processes in a timely manner; At the same time, strengthen personnel training, improve the standardization level of operations, and ensure that each process is strictly controlled. In addition, the project department strictly implements the safety and quality responsibility system, and takes measures such as on-site supervision throughout the process and special acceptance of key links to comprehensively ensure the quality of the project and construction safety.

As an important channel for the transportation of Yulin coal, the completion of the Shenwa Railway will significantly improve energy transportation efficiency and reduce logistics costs, which is of great significance for promoting the coordinated development of the Shaanxi Shanxi Inner Mongolia regional economy and serving the national energy security strategy. China Railway 23rd Bureau stated that the next step will be to closely focus on the node goals, optimize resource allocation, and promote the construction of Tianjiazhai Tunnel to a higher standard, ensuring high-quality and efficient completion of the connection task, and making every effort to create a benchmark project for railway construction.(This article is from the official website of Jian Dao www.seetao.com.
