Experimental Research on Protective Engineering of Chemical Sand-Fixation along Lanzhou-Xinjiang High Speed Railway Line
摘要
Abstract
Various properties of four kinds of sand fixing agent are analyzed based on laboratory tests,, and field tests are carried out in Yandun wind zone.Laboratory test results show that sand fixing agent viscosity decreases with the temperature increase and freezing occurs when the temperature is-20℃;the surface of sand fixing agent swells after being soaked in water, but the wind erosion is less than 1%;the average thickness of different solidified layers is ranked as type A>type B>type C>type D, and the thickness of type B is the most uniform;the mass loss of sand fixing agents are all less than 1%m, demonstrating good wind erosion resistance;the timeliness of type A is the best, Type A and D are the highest in cost.The field tests show that resistance to wind erosion of sand-box sprayed with sand fixing agent is obviously stronger than that of the sand-box without sand fixing agent, and the sand-box sprayed with sand fixing agent has played an effective role in sand fixing.关键词
