The first side of the Jinhai Bridge is smooth and smooth!It is expected that all the steel beams will achieve Helong in August

The majestic posture of the Jinhai Bridge is slowly exposing the waterway. On June 26, with the success of the steel beam with the number C7, the first side of the Jinhai Bridge successfully achieved the goal of Helong. As the section of the four main towers of the bridge, the China Railway Bridge Bureau is stepping up the lifting of the remaining steel beams of the Jinhai Bridge grinding knife section. All steel beams plan to achieve Helong in August.

Steel beam hanging is the focus of the current construction of the Jinhai Bridge. Except for the bridge part of the bridge, the main bridge steel structure with a total length of 1369 meters is consistent with 4 steel main tower, 8 large section steel beams, and 39 standard steel box beams (including 3 co -dragon blocks). Divide two sides of the side and one. Today, the four main towers have already stood on the water, and the eight large section steel beams have also been erected. The remaining 9 standard steel box beams are still stepping up.

The C7 steel beam block that was completed on the day was between the first and second main tower from Hengqin to the west. Steel beams are 6 meters long, 49.6 meters wide, 4.676 meters high, weighing 188.4 tons. After a series of operations such as the top push and promotion, with the help of the hanging rack, the steel beam slowly raised from 36 meters under the bridge to the bridge surface, and finally connected with other steel beams. The first span between the tower) The steel beam is high -precision. At this point, the bridge has successfully passed the connection of the steel beam from the east to the west of the west and the second main tower.

The Jinhai Bridge on the Wave Gate Waterway is a four -tower trapped bridge. According to the analysis and optimization of the construction organization of the China Railway Bridge, the steel beams between the four main tower were set up in two rounds. After the lifting frame is set up, the cable cable from the main tower to the bridge surface is also installed one after another. After the steel beam lifting rack is completed, the bridge surface is placed on asphalt and orbit to meet the traffic conditions. Nowadays, the steel beam rack has only the last nine Jinhai Bridge grinding the knife door section, and the majesty has been initially presented.

Jinhai Bridge is currently the widest public railway dual -use cable bridge in the world. The intermediate traffic dual -line design speed of 160 kilometers per hour (the second phase of the intercity of the bead machine). highway. After the second phase of the Pearl Motor will meet the operating conditions and the opening of the Jinhai Bridge, it will help the construction of a new comprehensive transportation hub of the Zhujiangkou west coast of Zhuhai, which will provide a solid guarantee for supporting the moderate diversified development of the Macau economy and the development of Hengqin Guangdong -Macao in -depth cooperation zone.
