The summer is clear and good construction. The hot soil in the Bay Area is full of energy. On July 24th, the Guangdong Provincial Transportation Group released news that after the 9th side of the 9th side of the deep and middle channel sinking tunnel on July 22 was completed, on the same construction window period, the 19th side of the tunnel was the 19th side of the tunnel. The pipeline (E19) also takes root in the sea smoothly. At this point, the installation length of the submarine tunnel pipe of the project is 4372.8 meters.

The Shenzhen -Middle Channel is a cross -sea cluster project that integrates "bridges, islands, tunnels, and underwater interoperability". The underwater tunnel is 6,845 meters long. Among them, the sinking pipe section is 5035 meters long. The world's first two -way eight -lane steel shell concrete sink tunnel. The E19 pipeline is a standard tube section, 165 meters long and weighs about 80,000 tons.

It is understood that, due to Typhoon Siaba No. 3 this year and the continuous heavy rainfall of the flood season, the Shenzhen -Middle Channel takes into account the overall work of production safety, and decides to share the same construction window period of the E19 and E24 pipelines. This is the first time in March this year to achieve two pipe sections in the same window period in the world, and once again challenged the "double -pronged approach".

At 15:40 on July 22, the world's first system of Shenluan Floating Transportation Installation "One Hangjin 1" dragging the E19 pipe festival was officially launched. Under the escort of the Guangdong Maritime Department, functions such as the DP automatic trace of the project scientific use of the project scientific use of the all -in -one ship, visual voyage recorder and other functions will be transferred to the sinking waters at 4:30 on the 23rd. Pressing and other processes, the E19 pipe section is completed at 15:30 on the same day.

At 8 o'clock on the 24th, after the agglomeration measurement was determined, the absolute deviation and relative deviation of the E19 tube festival were met in the design and evaluation standard requirements. The project plan will be completed during the year.
