A unique engineering project that has flared up in the depths of the Yellow Sea has reached the next important stage. As reported by CCTV News, the excavation of the main tunnel of another underwater road through the Jiaozhou inlet in the city of Qingdao was completed on June 2. This project is the largest, the most complex among similar disputes in the world.
Record scale and foldability.
Another underwater tunnel through the Jiaozhou inlet runs a distance of 17.48 kilometers. The main part of the tunnel, passed behind the giant tunnel complex (TPC) “Guohao”, is approximately 3255 meters long. In Dodatkovo, a service tunnel of 5854.6 meters was passed. The survey was carried out at depths of up to 105 meters under the level of the sea.
The Guohao TPK itself completed the excavation of the remaining section, installing the remaining previously prepared concrete ring section. This marks the completion of the stage of mechanized tunnel excavation.
The project features a complex design that includes two parallel main tunnels and one service tunnel. Doctors folded the geological bottom of the Jiaozhou tributary, the excavators used a combination of methods: mechanized tunneling using an additional TPK and the traditional drilling method. Narasi stage of buropodrіdrivnyh robots is already over 90%.
New transport artery for Qingdao.
The completion of another underwater tunnel will significantly improve transportation between the Shibei district and the New Western shores near the city of Qingdao. This new facility, together with the already existing first underwater tunnel across the Jiaozhou inlet (we will open in 2011, adding 7.8 km), a bridge across the Jiaozhou inlet and a circular skid road, will form. It is necessary to allow the place to move into the era of “underground tunnels”, which will essentially change the hour of dosage and allow the economic development of the region.
It is predicted that the service line for the tunnel will be completely completed at the end of the day or at the beginning of the next year. This will lead to the next stages of development and commissioning of the facility..
Another underwater tunnel through the Jiaozhou creek is not just a transport facility, but a testament to the current engineering capabilities that complex natural crossings provide for the sake of shortening people’s lives and developing infrastructure.
