Abstract

The invention provides a red sandstone improved construction method. According to the main technical scheme, an appropriate amount of improver is mixed into a red sandstone layer with a preset thickness below the design elevation of a roadbed for improvement, and is compacted into a viable roadbed soil layer. The improver consists of bamboo fiber and cement in a preset ratio. In the method, bamboofiber is added to red sandstone to pull aggregate in the red sandstone, so that the problems that the red sandstone is easy to soften and disintegrate in water, and the red sandstone surface layer iseasy to crack due to water loss are reduced, the red sandstone material of the abandoned soil can meet the requirements of backfill soil of the roadbed to be reused after being improved, a virtuous cycle of soil resources is achieved, the excavation, transportation and disposal of the original earthwork, and the purchase of new materials are reduced when a road is built, the construction cost canbe greatly reduced, and pollution caused by soil disposal is avoided. In addition, the bamboo fiber and cement are used to improve the red sandstone of the abandoned soil, so that the amount of cement is greatly reduced, and costs are further reduced.

Description

technical field [0001] The invention relates to the technical field of backfill soil improvement, in particular to a red sandstone improvement construction method. Background technique [0002] Due to the rapid development of transportation in recent years, the original road network composed of national highways and provincial highways can no longer meet the requirements of road transportation industry and economic development, and the construction of a large number of roads in various provinces and cities has become inevitable. In the new road, there is a large amount of red sandstone. Due to the particularity of the material itself, the whereabouts of a large amount of red sandstone excavation is in front of us. If it is not used as abandoned, it will cause waste of resources and increase investment. Abandoned earth will also occupy a large amount of land, causing water and soil conservation problems. How to turn red sandstone waste into treasure has become an important i...
