Suiguang expressway refers to expressway from Suining City to Guang 'an City, Sichuan Province. The line starts from Jinqiao Township, Pengxi County, Suining City, connects with Miansui expressway (G93), ends near Guang 'an City, connects with Nanguang expressway (G42), and passes through Guang 'an District, Yuechi County, Wusheng County and Pengxi County, with a total length of about 96 kilometers. Zhongda Consulting consulted all kinds of building websites and got relevant information about Suiguang expressway:
Highway introduction
Suiguang expressway is located in Suining City and Guang 'an City, Sichuan Province, and is one of the 11 new contact lines in the adjustment plan of Sichuan expressway Network Planning (2118-2131). Expressway network in Sichuan Province will be further improved to form the most direct and convenient expressway passage between Suining and Guang 'an, and it will also play a certain role in diverting the Suining-Guang 'an section of G42 Hurong Expressway. The route starts from Jinqiao Township, Pengxi County, Suining City, connecting Miansui (G93) expressway, passes through Gaoping Town, Sanfeng Town and Pengnan Town of Pengxi County, Saima Town, Jinniu Town, Longnv Town, Yankou Town and Feilong Town of Wusheng County, Guang 'an City, and Qifu Town of Yuechi County, and ends at Zaoshan Town, Guang 'an City, connecting Shanghai Rong (G42) expressway. The total length of the route is about 112.941km. The main highways crossing expressway are: lanzhou-chongqing railway, Miansui Expressway G93, Shanghai-Chengdu Expressway G42, Nanyu Expressway, the proposed Baguang Expressway, National Highway G212, Provincial Highway S314, County Road XJ14, County Road X121, County Road XX27 and County Road XX31. 2.2 technical standard: the whole line is constructed according to expressway standard with design speed of 81km/h and two-way four lanes, with asphalt concrete pavement and subgrade width of 26.1m；; Vehicle load grade: Highway: 1.
The road of humanization with highway characteristics
It only takes more than ten minutes to drive from Guang 'an downtown along Guangwu Road, and you will reach the Qifu exit of Suiguang Expressway in yuechi county.
This is an open site, with 21 parking spaces. Therefore, Guangxi Company combined with many years' operation experience of Chengdu-Chongqing Expressway, set up three temporary parking bays at Suiguang Expressway by using low excavation section, spoil ground, balancing earth and stone, cleaning landslide and other engineering measures according to local conditions during the construction period.
what are the benefits of temporary parking in the harbor? On the one hand, it provides parking space for maintenance machinery and faulty vehicles, on the other hand, it provides a temporary rest place for tired drivers and passengers, ensuring the smooth emergency "life passage".
Suiguang Expressway has also selected three sections of 3 km * * 9 km pavement to promote the drainage asphalt pavement technology. This technology not only solves the influence of water film on driving in rainy days, but also does not reflect light at night due to technology, shortening the braking distance of driving in rainy days, preventing the occurrence of vehicle sideslip accidents, and also has the characteristics of low noise and glare, which greatly improves driving comfort. The high-viscosity materials imported from Japan are mainly added, and the requirements for the hardness of aggregates are also high. The aggregates are all pulled from Puding County, Guizhou Province. When this technology is popularized on a large scale, the cost will be lower than the current pavement cost.
Feature 2: There are cherry blossoms, golden laurels and gesang flowers
In the Feilong service area of Suiguang Expressway, rows of cherry trees have been planted beside the parking spaces in the parking lot, and there are six cherry trees between the two parking spaces.
In March, you can come to Feilong Service Area to see cherry blossoms, and Jingui is planted in Pengnan Service Area. Therefore, in the construction of Pengnan Service Area and Feilong Service Area, expressway started from the details and strengthened people-oriented care, and put forward two construction concepts: shading and sponge.
Shading type refers to the use of American red maple, Cinnamomum camphora, Ginkgo biloba and other trees planted in small parking spaces, large parking spaces and tree array squares, which can be shaded in summer to avoid the impact of vehicle exposure on driving comfort. "Sponge" refers to a three-dimensional drainage structure consisting of "surface flow-field suction-underground drainage", which realizes accelerated and decentralized discharge and avoids the phenomenon of waterlogging and watching the sea.
not only that, but expressway in Suiguang adopted the scheme of "full vegetation coverage and evergreen in all seasons" to design the green landscape of the whole line in detail. Vegetation with low shrubs such as Magnolia grandiflora, Robinia pseudoacacia and Coriaria sinica was selected for ecological protection of subgrade slope, and grass flowers such as cosmos and Ophiopogon japonicus were mixed in it, which basically realized the ecological effect of full coverage of slope greening.
feature 3: the road to prosperity and prosperity
On the bridge deck of Vu Thang Jialing River Bridge, the only river-crossing bridge on Suiguang Expressway, with a total length of about 871 meters, there are two-way four lanes and 1.5-meter-wide walkways on both sides for pedestrians.
In the past, residents on both sides of Jialing River had to cross the river by boat. In the design of expressway, pedestrian walkways were built to facilitate the passage of residents in towns and villages such as Shipan Town and Longnv Town on both sides of Jialing River, which increased the cost by about 9 million yuan.
One highlight of Sui-Guang Expressway is Vu Thang Feilong Service Area, and Vu Thang Feilong Service Area, which is seamlessly connected with Baiping-Feilong Rural Tourism Resort, a national AAAA scenic spot, is also an open service area, and one side of the service area is not completely closed. Visitors can step out of the service area through the unclosed trail and come to the scenic spot to enjoy fishing, shopping, accommodation and other fun.
in heerkou village, Feilong town, wusheng county, there are 11 fish ponds built by cement castles, and leisure kiosks with different styles have completed the main project, while the ecological catering and ecological tea house on three floors have completed the main project. More than 1,111 mu of land in heerkou village, Feilong town is busy, and it is planned to rent 3,111 mu of land to build a farm integrating catering, leisure, hotels and picking. Sui-Guang Expressway is an economic channel that drives residents along the line to get rich and run towards a well-off society.
Significance of construction
Before the opening of Sui-Guang Expressway, Suining to Guang 'an only bypassed Chengdu-Nanchong-Guang 'an expressway or passed S314, lacking a high-grade road directly connecting Suining and Guang 'an. Suiguang expressway is a fast communication channel between Suining and Guang 'an in the east, which significantly improves the problem of bypassing the current situation, directly shortens the mileage by more than 51 kilometers, and further improves the layout of expressway network in the east of Sichuan Province.
Suiguang expressway will also strengthen exchanges and contacts between Suining in Chengdu Economic Zone, Guang 'an in Northeast Sichuan Economic Zone and areas along the Yangtze River in the east, represented by Chongqing and Wuhan, and form an east-west expressway between Chengdu and its far areas and Central and East China, so as to narrow the gap between the east and the west and bring its important economic and social benefits into play. Through Suiguang expressway, Sichuan Province will realize the most convenient "connecting the river to the sea" eastward, and at the same time, it will be connected with Miansui, Nanguang and Chongqing expressway networks, so as to strengthen the economic exchanges and contacts between eastern Sichuan and Chongqing, Wuhan and other cities in central and eastern China. There is no need to transit Nanchong from Chengdu to Shanghai.
