Microbial soil fixation component for cohesive soil, preparation method and soil fixation method
The invention discloses a microorganism soil fixation component for cohesive soil, a preparation method and a soil fixation method. The microorganism soil fixation component comprises microorganism bacterium liquid, microorganism solidification liquid and a soil penetrating agent. The microorganism curing liquid comprises urea, monocalcium phosphate and water; the soil penetrant comprises an alkynol polyether surfactant, a polyol type surfactant and water. The microorganism soil fixation component has good affinity permeability with exposed cohesive soil, can promote permeation of bacillus pasteurii microorganism bacterium liquid in the soil, and effectively solidifies the exposed cohesive soil through mineralization deposition of microorganisms. According to the soil fixation method, the permeable range of the microbial soil fixation components is considered, the microbial soil fixation components are fully utilized, and the viscous exposed soil body can be efficiently solidified. The microbial soil fixation component and the soil fixation method have the advantages that preparation is simple, construction is convenient, the soil fixation component can effectively apply fertilizer to topsoil, later topsoil vegetation growth is facilitated, and the microbial soil fixation component and the soil fixation method have the advantages of being ecological, environmentally friendly, economical and applicable.
本发明公开了一种用于黏性土的微生物固土组分、制备方法及固土方法，所述微生物固土组分包括微生物菌液、微生物固化液和土壤渗透剂。微生物固化液包括尿素、磷酸二氢钙、水；土壤渗透剂包括炔醇聚醚类表面活性剂、多元醇型表面活性剂、水。本发明的微生物固土组分与裸露黏性土体具有良好的亲和渗透性，能够促进巴氏芽孢杆菌微生物菌液在土体中的渗透，通过微生物的矿化沉积有效固化裸露黏性土。本发明固土方法考虑了微生物固土组分可渗透范围，微生物固土组分得到充分利用，可高效固化黏性裸露土体。本发明的微生物固土组分及固土方法制备简单，施工方便，且固土组分还能有效施肥表土，有利于后期表土植被生长，具有生态环保、经济适用的优点。
