Shaoxing Metro Line 2 02 bid "Yue Jin no. 1" shield started smoothly
On September 1, with the slow rotation of the blade of "Yuexin No. 1" shield machine, the shield machine of the left line of the section between Yuexi Road and Jinghu of Shaoxing Metro Line 2, mark 2, started smoothly.
Shaoxing Metro Line 202 is the first phase of line 2. The project consists of one station and two sections. It was officially started on November 16, 2020 and is expected to be put into operation by the end of 2023. Line 2 is shaoxing article 2 of the construction of the subway lines, as the backbone line in shaoxing city rail transit network, after the completion of the line will greatly promote the region linkage development, shaoxing depth into the Yangtze river delta integration development, expanding the scope of the city of radiation, for improving the urban comprehensive transportation network system, alleviate the urban traffic congestion, improve residents travel conditions, It is of great significance to promote shaoxing's economic and social development.
The originating the ~ mirror the interval length 1763 meters, is the longest in shaoxing no. 2 line of shield interval, in the process of excavation, "YueJin 1" will be across the wear on the three rivers and building more, overcoming the close side wear bridge pile foundation, through the soft soil layer, a recently frozen underground construction, fill in the connecting passage of shallow cover earth shield construction problems, such as, It is a great test to the technical requirements and safety risk control of construction.
To ensure the smooth advance, the interval of the project department strictly control, perfect the shield originating the preparation conditions, a clear division of labor, responsibility to the people, to the careful analysis and fully demonstrates the risk point, formulate special construction plan and emergency plan, adequate emergency rescue equipment, materials, and strengthen the construction of the ground monitoring, measures such as strict control of shield advance parameters, Prevent the displacement of the base and the destruction of the basement of the building caused by the land extrusion during shield construction, and avoid the deformation of the segment, the deformation of the joint bolt, fracture, water leakage, landmark subsidence and other phenomena occurred in the tunneling of the tunnel with small clean distance and small distance.
Next, the project will enter the shield construction for 5 months. All the staff of the project department will concentrate their efforts and overcome difficulties to complete each construction period node with quality and quantity guaranteed, and contribute to the urban construction force for the completion of Shaoxing Line 2 as scheduled.
