Yunnan Central Yunnan Water Diversion Project——
The construction of each tender section of the whole line is in full swing
Drilling tunnels, erecting arches, draining water, and checking for hidden dangers... In Shiping County, Honghe Hani and Yi Autonomous Prefecture, Yunnan, in the Jimichong Tunnel of the Central Yunnan Water Diversion Project, the construction work is non-stop day and night, and the workers are doing their best to ensure the tunnel's safety. dig.
There is a lot of water inflow and it is easy to collapse. It has always been a difficult problem for Jimichong tunnel excavation.
In order to ensure safe construction, the on-site management team conducted an in-depth analysis of the geological conditions. During the construction process, the water gushing from the tunnel face was first diverted and drained, and then the "double-liquid grouting" method was used to fill the cavities and gaps in the surrounding rock of the tunnel. , and finally use the "pipe shed method" construction to form advanced support.
At present, the Jimichong tunnel is steadily advancing at a speed of 12 meters per day, and it is expected to be successfully completed before the year.
"Tunnel construction is difficult and has high safety risks. Under such geological conditions, construction is a great test for us in terms of technology, safety quality, and construction schedule." Responsible for the Central Yunnan Water Diversion Project Hu Zhulu, the project leader of the China Railway Tenth Bureau, said the construction of the 1-2 bid in the Honghe section.
According to reports, in the face of complex and harsh geological conditions, the project department has repeatedly tried and summed up experience, and has gradually formed an operation process system with detection first, process control in the middle, and monitoring to prevent breakage, and achieved good results.
The Central Yunnan Water Diversion Project is one of the major water conservancy projects identified by the State Council. After completion, water can be diverted from the main stream of the Jinsha River, which is relatively abundant in water, to the central Yunnan area, benefiting 11.12 million people and improving and adding 1.13 million mu of irrigation area.
At present, the first phase of the water diversion project in Central Yunnan is progressing steadily, with more than 10,000 builders working in different positions in each tender section of the whole line.
