On May 28, 2020, the Natural Resources and Planning Bureau of Shaoxing City issued an announcement that China Railway and Beijing Urban Construction won the bid for the construction of the first phase of Shaoxing City Rail Transit Line 2 project. The details are as follows:

The starting point of the first phase of Line 2 project of Shaoxing City is Yuexi Road Station and the end point is Yuexing Road Station. The length of the line is 10.80 kilometers. They are all laid by underground lines and 9 stations are provided (of which Jinghu Station is line 1 In the same period), the Paojiang depot is set up, and two main substations are set up, which are the Olympic main substation (formerly Line 1 Jinghu main transformer, built by Line 1) and Paojiang Lianghu main transformer substation, The construction site is located in Shaoxing City and is planned to be completed in 2023.

The project is divided into 3 sections: China Railway Guangzhou Engineering Bureau 330 million yuan won the bid section SXGD2-TJSG-01; Beijing Urban Construction Rail Transit Construction Engineering Co., Ltd. 530 million won the bid section SXGD2-TJSG-02; China Railway 12 Bureau 6.4 100 million yuan won the bid section of SXGD2-TJSG-03.

The main scope of the civil construction 01 section (one station) is Yuexi Road Station (the net length of the base pit on the right side of the station is 507.976m, the net length of the left side pit is 502.945m, the net width is 18.90 ~ 27.7m, and the depth of the standard section is about 17.2 ~ 18.2m, the depth of the foundation pit at the west end of the well is about 19.2m, the depth of the foundation pit at the east end of the well is about 18.7m, and the depth of the foundation pit at the three-layer transfer node is about 26.2m. The foundation pit is constructed by open-cut method. The protective structure adopts 800-thick underground continuous wall, the transfer node adopts 1000-thick underground continuous wall, and five supports are provided along the depth of the foundation pit. The first is reinforced concrete support and the third is 800-diameter steel support (west side) The third and fifth channels at the end of the well are supported by steel with a diameter of 800, the third channel at the east end of the well is supported by concrete), and the rest are supported by a steel with a diameter of 609).

The main scope of the civil construction section 02 (one station, two sections) is Houshu Road Station (underground two-layer island station, the main structure is an underground two-layer reinforced concrete box structure, and the auxiliary structures are all underground one-layer structures. The foundation pit is net 198.1m long, net width 19.7 ~ 24.5m, standard section foundation pit depth is about 16.5m, effective platform length is 120m, platform width is 11m. There are 4 entrances and exits (including 2 reserved property entrances and exits), 2 sets of air pavilions, 1 A barrier-free elevator, a safety exit. The entrances and exits are set along both sides of Yangjiang West Road), Yuexi Road Station ~ Jinghu Station Section (Yuexi Road Station ~ Jinghu Station Section) Mileage SX20 + 491.571 ~ SK22 + 253.162 (XK20 + 489.000 ~ XK22 + 253.162), the vertical section is a V-shaped slope. After exiting Yuexi Road Station, the slopes are successively downhill at 26 ‰ and 9.768 ‰, and after reaching the lowest point at SK21 + 689.420, they are successively followed by 22 ‰ and 2 ‰ The slope reaches up to Jinghu Station, and the thickness of the covering soil is 8.425 ~ 18.028m. The section 1 # communication channel is set at SK21 + 090.000, and the 2 # communication channel and pumping station are set at SK21 + 689.420. Two communication channels and pumping station The freezing method is used for reinforcement, and the mine method is used for construction. The interval is constructed by the shield method), the distance between Jinghu Station and Houshu Road Station (the distance between Jinghu Station and Houshu Road Station) is: right line SK22 + 483.162 ~ SK23 + 429.334 , Long chain 7.543m, length 953.715m; left line XK22 + 435.662 ~ XK23 + 429.334, long chain 10.536, length 1004.208. The section is constructed by shield method).

The main scope of civil construction section 03 (second station and second section) is Zhongxing Avenue Station (Zhongxing Avenue Station is an underground two-story island station, the main structure is an underground two-story reinforced concrete box structure, and the auxiliary structures are all underground one-story structures. The net length of the foundation pit is 211.0m, the net width is 19.70 ~ 24.8m, the depth of the standard section is about 16.56m, the effective platform length is 120m, and the platform width is 11m. There are 4 entrances and exits, 2 sets of air pavilions, 1 barrier-free elevator, 1 Security exits. The entrances and exits are set along both sides of the Yangjiang Road and Ligushe planned roads, and Paozhong Road Station (Paozhong Road Station is the long-term Line 5 interchange station, the Line 2 station part and the transfer node will be implemented in this phase. It is a two-layer underground (partial three-layer) reinforced concrete box structure, and the auxiliary structures are all one-layer underground structures.
