The 259.5 km-long railway line and Yichang-Wanzhou railway under way link up at Liangwu Station. The line is the west section of Shanghai-Wuhan-Chengdu Railway Express Passageway in the Long and Medium-Term Planning for China's Highway Construction, the most important transverse railway passageway connecting China’s East, Middle and West, starting from Shanghai, through Nanjing, Hefei, Wuhan, Yichuan, Chongqing to Chengdu, crossing 4 provinces (Jiangsu, Anhui, Hubei and Sishuan) and 2 municipalities (Shanghai and Chongqing).

The construction period of this project is 5 years (initiated from 2008, and completed in 2013), with the total investment for this project is RMB 26.183 billion yuan, and design short-term stage shall be in 2020, and 2030 for long-term stage.



The main technical standards for the main line of Chongqing-Lichuan railway:

Grade of railway: State railway, grade one; Number of main lines: double-line railway Target speed of passenger train: 200km/h The minimum radius of curve: 3500m Traction mode: Electric Traction mass: 4000t Track type With ballasted bed; the jointed track is adopted for truck road

diversion, with jointless track for the rest in the hub of Chongqing.

1.1.3 Main Engineering Contents

Along the whole Chongqing-Lichuan line, there are 118 new-built bridges totaling 48386.4 linear meters; 222 culverts with 8108 linear meters in length and 60 tunnels with total length of 166,360 m. Therefore, the overall length of bridges and tunnels is calculated as 214.7 km, accounting for 82.7% of the whole line.

The total volume of earth and stone for the whole line is 5901.1×104 m3 cubic meters, among which, 5425.2 ×104 m3 cubic meters for excavation, 475.7×104 m3 cubic meters for filling and 4967.4×104 m3 for spoil. 93 spoil grounds have been arranged.

7 new railway stations will be built including Miaoxian North Station, Changshou North Station, Fuling North Station, Fengdu Station, Shizhu Station, Shaziguan Station and Liangwu Station; and Chongqing North Station will be expanded along the whole line.

Permanent/temporary occupation of land is 623.7 hm2 and 579.0 hm2 respectively along the line.

New storage and departure yard for MU train will be built in North Chongqing. 16 storage and departure sidings, production and living facilities like train’s finish cleaning, vacuum drainage, signal, comprehensive operation and apartments of train crew will be provided in the near future.

Passenger Train Technology Preparation Facility at Chongqing North Station will be reconstructed.

7 new traction substations will be built including Miaoxian North Station, Changshou North Station, Fuling North Station, Fengdu Station, Shizhu Station, Shaziguan Station and Daxikou Station; and the existing traction substation at Chongqing North Station will be rebuilt along the whole line.

The floor area of the buildings along the line is 127, 920 m2, of which that of houses for living is 2550 m2, and supporting facilities for production and living including water supply and drainage, heating system and air conditioner.

Newly-built roads for vehicle transport is 139 km, and reconstructed local road is 255 km. There are 1 Beam Fabricated Factory, 4 Concrete Mixing Plants, 4 Material Plants and 4 temporary wharves.



1.1.3 Characteristics of This Project

Chongqing-Lichuan railway line is situated in the parallel mountain ridges and valleys of the transition zone from the northeastern foot of Yungui Plateau to the eastern edge of Sichuan Basin, with a sharply undulating terrain, crossing hill area, low mountain area, middle mountain area and middle mountain haystack area along the whole line. Land along the line is predominantly used as cropland and forestland, with high forest coverage rate and abundant rainfall. Trees will be cut down during the construction, disturbing the native vegetation. The newly-built and reconstructed roads for transportation is 494 km, particularly paying more attention to water and soil loss caused by temporary works in the mountainous area like new construction roads and camps. There are new 60 tunnels along the whole line, totaling 166,360 m in length. The construction of some tunnels in the karst development region is likely to lead to water-leaking and loss of surface water which could exert influence over farmland irrigation, vegetation growth and domestic water of local residents. Therefore, the monitoring on the top of lava tunnel and surface water level fluctuation nearby shall be strengthened throughout the entire construction period and actions shall be taken to prevent the loss of surface water from affecting production and daily life if necessary . The total spoil is 4967.4 × 104m3, of which spoil from tunnel is massive, up to 3318.7× 104m3, accounting for 67% of the total. The establishment and protection of spoil grounds is the key to reduce water and soil loss and protect the ecological environment; in particular, ones in the deep slopes and clough are important; otherwise fragments of stones would slide down due to improper setting and protection in the storm seasons causing river blockage, farmland flood or other natural disasters. There are 118 newly-built bridges along the line with the total length of 48386.4 linear meters. Thereinto Qingxi Yangtze River Major Bridge (Renamed as “Hanjiatuo Yangtze River Major Bridge”) is in the passage for fish migration in Yangtze river basin; nursery ground and spawning ground for fish are in the upstream and downstream of the bridge site. Longxihe Super-major Bridge is located in the upstream of Level II Natural Preservation Zone at the Water intake of Miaoshan Water Plant, Changshou County. Effect on the water quality of the river and fish spawning by the construction of in-water piers and measures shall be focused on during the bridge construction along the whole line. Through Yunfengshan Forest Park in Chongqing in the form of tunnels, bridges and cuttings, and through City-level Forest Park in Nanmuyuan in the form of tunnels, near Xingdoushan Natural-level Natural Preservations Zone and Baiyan Scenic Spot, Zhangguan, Chongqing municipality, the construction of Chongqing-Lichuan railway will have an effect over local ecological environment in these natural preservation zones. Ancient trees thrive at both sides of the line; therefore actions should be taken to protect them. Note: Data of engineering volume referred in the section is the data in feasibility study.

status Remarks

Remarks 1. Fugitive dust from construction site and roads has been resolved by sprinkling water at construction site



and if more dust at construction site, conduct the sealing treatment (e.g. Mixing station) with more-frequently watering to keep ground surface wet. Another way to reduce dust adopted is the hardening treatment of site roads and construction site.

2. Leaking water of tunnels shall be flowed into sedimentation tank and then discharged up to the standard. 3. Spoil of tunnel shall be discarded at spoil grounds along which retaining walls are being constructed. 4. No cultural relics have so far been found at the whole zone of piping construction. 5. Color-bar cloth shall be used to cover materials entering the site or placed in storehouse.


The on-site investigation results of monitoring are: Dutingshan tunnel: the construction site appears tidy and orderly; construction roads are arranged neatly with distinct border; watering carts are provided; air compressor stored inside air compressor room; billboards of environmental protection are available; garbage bins have been set up at construction site; three-stage sedimentation tank for sewage from production with billboards is available; temporary retaining wall is being built at spoil ground. Living areas and offices of 1# Inclined Shaft Team of Dutingshan Tunnel: standardization construction of construction camp goes well; there is billboard of environmental control system; carrying out greening; garbage bins and pools available for categorized collection of garbage; and septic tank available for treatment of sewage.

5.2 Results and Analysis (1) Internal management Each construction unit has established the internal management system in accordance with the requirements, set up the organizational structure and measures for environmental protection, arranged the full-time/part-time environmental protection management personnel and defined the duties and responsibilities of each department. (2) Construction of tunnel Of the construction of tunnel, the main issues are the disposal of dreg from the tunnel and the protection of construction platform. (3) Construction of bridge Most of the bridges have not started their construction and are still in preparation stage. Each unit has arranged the slurry sedimentation tank for the bored piles. (4) Protection of construction pavements The construction pavements set up by each construction unit are normal and are maintained by specially-assigned people. Water spraying vehicles are equipped by the construction units to prevent the dust pollution. (5) Construction camp site Garbage bins and tanks are arranged for each construction camp site. The domestic garbage is collected and sent to the local environment sanitation administrative department for treatment. The railway line is situated in the mountainous regions with many bridge-tunnel connection sections. Pay attention to the protection of side slope at construction camp sites and the construction sites. (6) Bulletin board All construction units have set up Bulletin boards at the construction camp sites and the construction sites, but they limit themselves to the propaganda of measures for environmental protection and administrative system of environmental protection and have not arranged the signs that can let the public around know about the person in charge of the environment protection for this construction section and the telephone number for complaint of environmental protection.



6. Popularization-worthy Measures as well as Problems and Suggestions

6.1 Popularization-worthy Measures (1) The setup of roads and construction sites is standard and the boundary is clear for Paihuadong

Tunnel and Liangchanghe Mixing Station under China Railway 12th Bureau Group Co., Ltd.. (2) Side slope had been protected by hydroseeding at the construction site of Huangcaoshan

Tunnel under China Railway 11th Bureau Group Co., Ltd., combining slope setup with planting.

(3) The setup of the construction site of Jianfengding Tunnel under China Zhongtie Major Bridge Engineering Group Co., Ltd. is standard, harmonizing with natural landscape; Retaining wall was under construction for Caijiagou Super-major Bridge to prevent water and soil loss effectively.

(4) Categorized collection of garbage is adopted by China Railway Tunnel Group Co., Ltd. for the construction site of Fangdoushan tunnel.

(5) The setup of the construction site of Wanshoushan Tunnel under China Railway 18th Bureau Group Co., Ltd. is standard, and posters of environmental protection are put up at the construction camp.

(6) Retaining wall and water interception and drainage facility were under construction for spoil ground of Dutingshan Tunnel under China Railway No. 5 Engineering Group Co., Ltd., and slope was protected by combing the slope setup with planting; large coverage area of forestation is available.

6.2 Existing Problems and Improvement suggestions (1) Each unit has not defined the person in charge of the environmental protection and the

supervision telephone number on the billboards on the construction site. It is suggested that they should be publicized on billboards as soon as possible so that the public can make supervisions.

(2) It is found during this on-site inspection that no retaining walls or water interception and drainage facilities have been arranged for the spoil of each tunnel. Each unit is required to make retaining walls before the disposal of spoil from each tunnel and enhance the retaining walls and water interception and drainage facilities of spoil grounds.

(3) It is suggested that oil tanks out of use be removed from the construction sites; harden the ground surface on which oil tanks are placed and set cofferdam and devices for collecting used oil; oil tanks be placed together on the hardened surface with cofferdam, and oil groove provided for temporary use of oil tanks; shelters are available for these places so as to prevent pollution caused by loss of used oil in the rain.

(4) Chongqing-Lichuan Railway Construction Co., Ltd. is suggested to require the construction units to setup billboards of environmental protection at the construction boundary prior to the construction at key ecological environmental protection zones including water resource protection zones, natural preservation zones and scenic spots, with the purpose to remind the construction staff of entering the environment-sensitive regions, and put forward precautions on environmental protection.

(5) It is suggested that Chongqing-Lichuan Railway Construction Co., Ltd. push forward the supervision units and construction units for the project to carry out the self-checks of side slope protection for the spoils of tunnel, construction sites and camps so as to reduce water and soil loss.

(6) In accordance with the requirements from Ministry of Environmental Protection, it is suggested that Chongqing-Lichuan Railway Construction Co., Ltd. request the supervision units of this project to report the environmental protection supervision work periodically and submit the summary report of environmental protection supervision after completion of this project.
