Guide: at about 10:00 on December 21, the Guanyinshan tunnel of Lou Shao railway constructed by the second Engineering Co., Ltd. of China Railway Construction 25th bureau group was successfully transferred to the main tunnel construction, which marks a new page in the tunnel construction. It is reported that the Guanyinshan tunnel is 1165 meters long and is planned to be completed by the end of April 2012. Because

at about 10:00 on December 21, the Guanyinshan tunnel of Lou Shao railway contracted by the second Engineering Co., Ltd. of China Railway Construction 25th bureau group was successfully transferred to the main tunnel construction, which marked a new page in the tunnel construction

according to the introduction, the Guanyinshan tunnel has a total length of 1165 meters and is planned to be completed by the end of April 2012. The sales increased by 20% from last year. The location is rich in coal resources and has a very high gas content. At the same time, due to the exploitation of small coal mines in history, the super long journey can fully meet the testing of materials with super large deformation rate; The goaf and loose accumulation formed in the tunnel body and its adjacent areas, coupled with the concentrated development of karst, Guanyinshan tunnel is known as "the most dangerous tunnel of Lou Shao Railway"

in order to build this most dangerous tunnel into a safe tunnel, the Lou Shao railway project department has taken a number of effective measures. According to the requirements of "four standardization", the labor personnel are not allowed to carry out pre job construction safety quality training and examination for all the experimental speed or force values that are considered to be it, and those who pass the examination are allowed to enter the site for operation; Select technical backbones, formulate special construction schemes for each process, and optimize the design of ventilation, power supply and other pipelines; Implement strict technical and safety disclosure; Equipped with all kinds of safety production equipment, a special gas monitoring team has been set up to pay attention to the gas situation in the tunnel at all times; It also carried out enterprise university cooperation with Central South University to strengthen the advance geological prediction, and practically achieved "one strengthening, three leading and four in place", so as to ensure safe production
