La section Steam-Waterfront de la ligne de métro Dongguan de la rivière Zhongshan 1 A été complété avec succès
L'après-midi de juin 29, avec l'effondrement du béton du mur de liaison au sol à l'extrémité de réception du terminal de bus, la tête de coupe de China Railway Shanhe 27 atteindre, construction machinery part marking that China Railway Shanhe successfully completed the excavation task of the right line of the steam-bin section of Dongguan Metro Line 1.
In June 2021, Chemin de fer chinois Shanhe 27 la machine sera conduite depuis la station du stade Binjiang. During the construction period, due to the owner’s decision on the site selection of the bus terminal station, it will be shut down for about 13 months in the tunnel. The high-temperature and humid environment in the tunnel for a long time is a great test for the performance of the equipment. In October 2022, the China Railway Shanhe 27 machine began to push the excavation, and the inspection units tested and evaluated the equipment before the restart, et PC60Z Bucket Adapter the performance indicators all met the requirements of the excavation, which once again proved the reliability, solid and durable of the China Railway Shanhe Shield machine.
The steam-shore section of Dongguan Metro Line 1 has a total length of 1011 meters. The main geology is medium and strong weathered calcareous mudstone, silty soil, and mixed fill soil, etc. Along the way, the tunnel passes through Dongjiang River Road, Quhai Bridge houses, Quhai Bridge pier pile foundation and other major risk sources, especially the Dongjiang River channel is a navigable river in the city, et 4634034 John Deere 27D seal kits the tunnel top is only 8 meters from the riverbed at the shest buried depth. Control of gushing and water seepage construction machinery part has become the focus of the project.
The soil bin visualization system installed by China Railway Shanhe Shield Tunneling Machine provides a strong guarantee for the construction of this section. During the excavation process, 13065627 Filtre à air the situation in the soil bin can be observed in real time, and corresponding measures can be taken according to the situation, which ensures the safe, smooth and efficient crossing of Dongjiang River by the shield tunneling machine, and has been highly recognized and praised by the project department.
The successful completion of the project is another major milestone for China Railway Group to move south to Guangzhou, et construction machinery part once again contributes to the high-quality development Galet de roulement DH220 of the Guangdong-Hong Kong-Macao Greater Bay Area.
