2021-07-09
The subgrade of the 19th contract section of Yongshun-Jishou Expressway is about to be completed. In view of the fact that this section is one of the main transportation channels for the subsequent main line construction and connects Jifeng Industrial Park in Jishou City, several villages and towns along the route are all accessed by this road. In order to ensure the passage without damaging the completed subgrade, based on the principles of economy, rationality, applicability and environmental protection, closely combined with the characteristics of the section, adjust measures to local conditions, reasonably select materials, and make full use of the abandoned weathered gravel along the line, it is proposed to popularize and apply the new technology of bio-enzyme soil solidification in the section L2K 0 000-L2K 10 300 of the 19th contract section of Yongji Expressway to meet the current functional requirements.
