摘　　要：人工集流场常用的防渗材料有混凝土、聚乙烯薄膜和沥青玻璃丝油毡等,这些材料的集流效率高,但是存在造价高或耐久性差的缺点。应用土壤固化剂修建集流场,能够有效解决集流材料造价高和耐久性差等问题。在阐述MBER土壤固化剂的组成和固化机制、原材料的技术要求、配合比设计和集流场结构设计等基础上,重点研究土壤固化剂集流场的施工工艺,提出了在干硬性施工工艺中混合料的均匀性、含水率和施工时间是应用固化剂修建集流场的关键技术,建议加强对塑性施工工艺的研究。Flow collecting plot is an important component of collecting rainwater for irrigation impermeable materials of artificial catchments area include concrete, polyethylene film and asphal The ordinary ted fiberglass oil sheeting, which have high flow collecting efficiency but have some weaknesses of high cost or poor durabili- ty. The soil stabilizer applying to the flow collecting plot in water harvesting system can solve effectively the above-mentioned problems, so it is paid attention to increasingly. Based on introduction of the composition and the solidifying mechanism of the MBER soil stabilizer, the requirements of the raw material and the design of the proportion and structure, construction technique and advances are focused on that the equality, water contents and the construction time of mixture are key points of dry mixture construction technique. Finally it is suggested that plastic mixture construction technique should be enhanced.
