Source: Hits:Congratulations , on May 2nd , 2019 ,GEODA have got the CHANG CHUN METRO LINE 2 project from domestic sales agent , the cast in channel type is GXA 30/20
The operation of the subway has led to the construction of one after another tunnels. In order to ensure that the tunnel is not damaged by the fatigue vibration of the
contact network, the fine installation requirements of the high-speed contact network are met, and the high-speed railway tunnel slot embedded parts are used in the contact network hooks in the tunnel. Technical solutions,
The tension and shear force at each bolt are calculated in the tunnel according to the wind speed of 49 m/s. It is determined that the contact network is based on the high-speed
rail tunnel type embedded parts. Load requirements, safety performance requirements and installation requirements are determined.
2) Ensure that the force and vibration of the contact net do not damage the integrity of the tunnel lining, and at the same time achieve the fine installation standard of the high-speed contact net,
and also meet the strength requirements of the train wind power to the installation equipment and the buried foundation in the tunnel.
Three advantages indicate that the use of tunnel slotted embedded parts in subway tunnels is a very effective way. This time, we will cooperate with Changchun Metro Merchants to contribute
to the national infrastructure and make a satisfactory answer for road traffic.
