Latest construction progress of southwest ring road of regional express railway
One-time power transmission of southwest ring road of metro was successful.
At 3: 30 in the morning of 20021August 14, the one-time transmission of the southwest ring line of Guiyang Express Railway was successful, marking another step forward for the railway to leave the service.
In the next step, the Southwest Ring Road will carry out thermal sliding test, joint debugging test and operation test as planned. It is expected to meet the opening conditions in September this year and put into operation during the year.
Introduction of Guiyang Regional Express Railway Project
The main line of Guiyang Express Railway Project is 366 kilometers long. This project includes six sub-projects, consisting of "one ring, one shot and two lines" and Guiyang Railway Freight Center.
The "First Ring Road" consists of Guiyang hub Baiyun-Longli North Ring Road (Northeast Ring Road) and Xiaobaijingqing Town East Baiyun Ring Road (Southwest Ring Road);
"One beat" is the Guiyang-Kaiyang express railway (your opening line;
The "two connecting lines" are Jiuchang-Yongwen Railway and Qingzhen-Lindanan-Zhijin Railway.
The project connects Guiguang, Shanghai-Kunming, Cheng Gui, Chongqing-Guizhou, Guinan and other completed or under construction railways. Upon completion, an "M"-shaped rapid passenger transport network will be formed with Guiyang as the center and connecting the surrounding major urban agglomerations, forming a half-hour urban life circle, a 1 hour economic circle for major cities in the province, and an 8-hour traffic circle for major cities such as Beijing and Shanghai.

Introduction of Southwest Ring Road Project of Guiyang Regional Express Railway
The full name of the southwest connecting line of Guiyang Express Railway is: the third bid section of the southwest connecting line of the newly-built Xiaobaijing Qingdong Baiyun connecting line railway project, which is actually the Guiyang connecting line railway.
The total length of the line is 8 1. 1km, the total length of the tunnel is about 53km, and the bridge-tunnel ratio is nearly 70%.
Southwest ring line route
The line starts from Longdongbao area;
After going west to Huaxi and Tianhe Lake, bypass Gui 'an, Qingzhen, Jinyang and Baiyun;
It is connected with Baiyun-Xiaobi Railway of Northeast Ring Road;
Thereby forming a rapid passenger railway around Guiyang.
Southwest ring road function
Compared with the previous railways and BRT, the Southwest Ring Road of Guiyang Urban Rail Transit mainly serves urban public transportation, and organizes the hub ring road to slow down. According to the development, planning and passenger demand of cities along the route, it organizes different hub ring roads and outer ring roads to slow down.
Some lines (mainly the Northwest Ring Road) take into account the functions of railway trunk lines, and organize cross-line trains on some channels as needed.
Significance of southwest ring road construction
Guiyang is the only provincial capital city in China to build a regional loop railway;
After the completion of the Southwest Ring Road, it will seamlessly connect the main urban area of Guiyang and Gui 'an New District, mainly undertaking passenger transport tasks. It will bypass Guiyang-Gui 'an for about 45 minutes by bus operation, which will also greatly improve the traffic speed of Guiyang and accelerate the integrated development of Guiyang-Gui 'an.
Guiyang Rail Transit Line 3 Rail Transit Line 3
Huaguoyuan east station
Energy transfer complete.
2021June 10, the power line relocation and reconstruction project of Huaguoyuan East Station of Guiyang Rail Transit Line 3 was completed, which opened the key link of integral piling and excavation of the main station building.
Huaguoyuan East Station is the largest and most complicated station in the whole line, with a total length of 7 18m and an entrance and exit of 2 1.
This pipeline relocation project * * * has 4 1 10KV power lines, 78 10KV power lines and 25 sets of power equipment, involving multiple property rights units. In the process of relocation, the verification of pipeline resources, the formulation of relocation plan, the construction of pipe trench and the coordination of power failure are all difficulties.
The completion of this relocation task has cleared a big obstacle for the overall piling and excavation of the main body of Huaguoyuan East Station of Guiyang Rail Transit Line 3.

Main structure capping
On July 23rd, 20021year, the main structure of Wenquan Road Station of Guiyang Rail Transit Line 3 was successfully capped.
The successful completion of the project marks the completion of the main structure of the station in this bid section.
This contract section includes one station, two sections and one substation (Wenquan Road Station, Chadian Station-Hai Shun Station, Hai Shun Station-Wenquan Road Station and Xintianzhai Main Substation) with a total length of 4. 13km.
Wenquan Station is the second largest station of Guiyang Rail Transit Line 3, located under Xintian Avenue in Wudang District. It is an underground island platform with a total length of 484.2m, a standard section width of 22. 1m and a foundation pit depth of 22.43-27.41m. The station has 10 entrances and exits, which are located on the main road of Xintian Avenue.
Line 3 Chadian Station ~ Hai Shun Station
Right-line shielding source
On July 24th, 20021year, with the cutter head of "Qianjin No.20" shield machine slowly moving forward, the right line shield machine of Chadian Station-Hai Shun Station of Guiyang Rail Transit Line 3 was successfully started.
The "Qianjin No.20" shield machine in Chashun section starts from Chadian Station, travels along the southern section of Xintian Avenue to Hai Shun Station, and is received at Hai Shun Station.
The total length of the right line of the shield construction section is 1388.0 17m, the buried depth of the tunnel is about 13.2 ~ 40.5m, and the minimum plane bending radius is 650m. The longitudinal slope of the line is designed as a single slope with a maximum slope of 27.6.
The successful off-line of "Qianjin No.20" shield machine is the last main site of the "one station, two sections" construction task in this bid section, and it has officially entered the implementation stage, laying a solid foundation for the smooth completion of the overall project period.
Taohuazhai Station on Line 3-Huaxi South Station
The left line runs smoothly.
On the evening of July 3 1, 20265438, the left line of Taohuazhai Station-Huaxi South Station of Guiyang Rail Transit Line 3, which was built by China Railway Shanghai Engineering Bureau, was successfully connected.
At this point, the interval has achieved double-line penetration.
The left line of Taohuazhai Station-Huaxi South Station, which runs through this time, starts from the small mileage end of Huaxi South Station and goes south along Qingxi Road. Pass through the Meng Xi Road pull-down trough and Yangliutang Tunnel on the southwest ring road, and reach the receiving well of Taohuazhai Station at the end of the mileage. The total length of this section is 952 meters, the minimum curve radius of the line plane is 650 meters, and the maximum longitudinal slope is 33.6. The longitudinal slope of the line is V-shaped, and there are communication channels and pump houses in the section. The geological conditions in this construction area are complex, mostly dolomite, argillaceous dolomite and other uneven soft and hard strata, with many caves, rich groundwater, high pressure, many risk sources and great construction risks.
Next, the ancillary structure of this bid section will be synchronized with the main shield project of Tao Tong section, and strive to complete the construction task as soon as possible.
Tongmuling Station of Line 3-Taohuazhai Station
The last shield is activated.
On August 4th, No.2021,172 shield machine sailed from Taohuazhai Station of Guiyang Railway Jiaoyuntong Line 3 to Tongmuling.
