Muck trucks, loaders shuttling back and forth, excavators waving long arms... On October 27, at the pier on the right bank of the Guansheng Bridge in Guang'an District, the equipment roared, and the construction team was seizing the rainless weather (time period) to step up the operation, and the scene was a hot construction scene. It is understood that this is the guansheng bridge project in Guang'an District on the right bank of the Qujiang River that is under construction to the Xiaojiagou embankment project.
Located in the zhongqiao street office and Guansheng Town, the Guansheng Bridge to Xiaojiagou Embankment Project on the right bank of the Qujiang River is a key people's livelihood project supervised by the Guang'an District Water Bureau and implemented by the Guang'an Lingang Economic Development Zone Management Committee, with a project grade of IV. and a total investment of 40.64 million yuan. The upstream of the project starts from the pier on the right bank of the Guansheng Bridge, and the downstream ends at the bedrock of the slope of Xiaojiagou, and the construction began in April 2021, with a total construction period of 540 days, and is expected to be completed and accepted in August 2022.
"The total length of the embankment is 2.688 km, designed according to the 20-year flood control standard, the design of the top of the embankment elevation is 235.5 meters (the highest 236.5 meters, the lowest 234.5 meters, at the height of 228 meters set up at 228 meters elevation, the maximum height of the embankment is 20.25m, the embankment foot is set with concrete tooth wall protection, it is a slope-type embankment using concrete grid ecological slope protection + concrete panel slope protection, and the slope ratio is designed according to 1:2.0." Ding Zhongping, director of the quality supervision station of the Guang'an District Water Bureau, told reporters that in the perennial flood level of 228 meters above the elevation set up horse road, the width of the road is 3.00m, the water surface below 228 meters elevation using concrete panel slope protection, hydrophilic platform as the basis for panel slope protection. Above the elevation of 228 meters above the horse road, concrete frame lattice beam embedded ecological grass protection slope, the project contains 3 box culverts (width× height): Guangshui Bridge box culvert 2 meters × 3 meters, Guanshenggou box culvert is 4 meters × 6 meters, the old wharf ditch box culvert 3 meters × 4 meters.
Why is the Guansheng Bridge to Xiaojiagou Embankment Project built? It is reported that because Guang'an is located in the middle and lower reaches of the Qu river, the location of towns along the river is low, and it is seriously threatened by flooding. The statistics of the past ten years show that the number of floods in the canal river during the flood season is generally 15-20 times each year, the flood is prone to occur, and the peak height is large, the maximum variation of the flood level is more than 20m, the flood in 2010 reached 25.81m, and the flood in 2011 reached 26.1m.
Guang'an Lingang Economic Development Zone is located on the right bank of the Qujiang River, some areas are in the flooded area, the construction of embankment projects with a certain scale, as a guarantee line for the safety of people's lives and property, has become an urgent need, and this is also one of the important contents of urban infrastructure support. Zhang Hongshuai, director of the Management Committee of Guang'an Lingang Economic Development Zone, said that after the completion and commissioning of the project, it will effectively protect the farmland of about 0.55 million mu and the safety of 11,800 people's lives and property within 4.21 square kilometers of the Lingang Economic Development Zone. At the same time, through the regularization of the riverbank, it is possible to effectively use the water environment of the canal and river, combine the landmark landscape and commercial building landscape to create a riverside leisure and cultural landscape, and form a multi-dimensional ecological comprehensive area of cultural entertainment, tourism services and urban industry, which is conducive to improving the city's taste, improving the living environment, and promoting the substantial appreciation of the surrounding land.
"At present, 130,000 square meters of earth and stone, No. 1, 2 and 3 through the embankment culvert and some municipal pipe networks have been completed, and the construction of the embankment body and the construction of pipe culverts and box culverts is currently underway." Chen Sheng, the person in charge of the project site, said that the next step will be to seize the good weather, accelerate the construction progress, and ensure that the project is completed on schedule according to quality and quantity.
