(一) 利用某些化学药剂凝固硬化的特点,对各种松散破碎的岩石和土壤进行胶结加固,以达到堵漏、止水、防渗、加固孔壁、补强基础等目的,是地质勘探、矿山开采、铁道建筑、水电施工常用的办法之一。随着塑料工业的发展,利用合成树脂等高分子聚合物作为灌浆材料的研究,是从五十年代开始的。1951年美国氰胺公司利用丙烯酰胺进行灌浆试验,经过七年提出了AM-9注浆法。1955年日本也生产了“日东-SS”丙烯酰胺类灌浆剂。十多年来,美、日、法等国已将丙烯酰胺灌浆剂大规模应用于矿山隧道、水坝地下工程的防渗、止水等方面,取得了较好
(1) Using the characteristics of solidification and hardening of certain chemical agents to cement and loosen various loosely broken rocks and soils to achieve the purposes of plugging, water stopping, seepage prevention, reinforcement of hole walls, reinforcement of foundations, etc. One of the commonly used methods for mining, railway construction, and hydropower construction. With the development of the plastics industry, the use of high-molecular polymers such as synthetic resins as grouting materials began in the 1950s. In 1951, cyanamide company in the United States used acrylamide for grouting tests. After seven years, the AM-9 grouting method was proposed. In 1955, Japan also produced “Nitto-SS” acrylamide grouting agent. For more than a decade, the United States, Japan, France, and other countries have applied acrylamide grouting agents on a large scale to prevent seepage and stop water in mining tunnels and dam underground projects, and achieved good results.
