In view of the serious lag in the construction of the subway station No. 4 railway station and the difficulties in engineering such as the East Throat Zone of the railway station, the project department of the No. 4 railway station station invited intelligent robots as helpers.
The reporter learned that the railway station project will be constructed in two phases: the first phase is the tunnel excavation construction, and the second phase is the station open excavation construction. "The two underground tunnels of the railway station are under the east throat area of ​​Xi'an Railway Station Station. The control requirements for the settlement of the ground surface are extremely high. Together with the long tunnel of the railway station, the geological area is silty clay and the groundwater level line. It is 5 meters, the tunnel depth is only 10.5 meters, and the geological conditions are complicated. In addition, the construction work site at the southern end of the station has seriously affected the overall project planning of Line 4 due to the delay of demolition work. The relevant person in charge of the bureau said that in order to complete the construction tasks in quality and quantity within the specified time, the project department used 10 new technologies to assist efficient construction. Recently, intelligent tunneling robots were also introduced from Switzerland.
On the afternoon of February 27th, the intelligent tunneling robot imported from Switzerland was excavated in the tunnel of Xi'an Metro Line 4.
Yesterday (February 27th) afternoon, at the construction site, the reporter saw this "little guy" shaped like a mini excavator. It is flexible and can enter narrow working faces and dangerous places. It can also be used for 24 hours of uninterrupted operation with digging heads and hydraulic hammers. The staff only needs to use remote control on the side, which saves labor costs and improves work efficiency. The electric working method is also very environmentally friendly.
