摘要

通过使用表面活性剂和固化剂的添加剂组合物，考虑了在盐渍土的分散体中形成防水结构的可能性，通常提供分散硬化的效果。本文介绍了以康格勒碱厂废料为基础，采用复合添加剂对苏尔坎达里亚地区砂进行固砂的试验数据。结果表明，复合添加剂固定盐渍土的基础是表层(不超过5 cm)由自由分散状态转变为凝聚分散状态，形成由> 1.0 mm的防水大团聚体组成的结构(外壳)，机械强度可达3.0MPa。

Fixing mobile desert sands: definition of water resistance, mechanical strength and mechanism of fixing

The possibility of the formation of a water-resistant structures in dispersions of saline soils by using a composition of additives combining a surfactant and a fixing agent, generally providing the effect of dispersed hardening, is considered. The data by investigation of method of fixing the sands of the Surkhandarya region with complex additives obtained on the basis of the waste of the Kungrad soda plant are presented. It is shown that the basis of the proposed method of fixing saline soils with complex additives is the process of converting their surface layers (up to 5 cm) from free-dispersed state to coherent-dispersed state by forming a structures (crust) consisting of water-resistant macroaggregates > 1.0 mm with mechanical strength up to 3.0MPa.
