The invention discloses a resin-based spiral spike anchoring agent for a railway sleeper. The resin-based spiral spike anchoring agent comprises three components of A, B and C, wherein the component Aconsists of 80-95% of bisphenol A epoxy resin and 5-20% of epoxy resin with a single epoxy group; the component B consists of 92-100% of modified fatty amine and 0-8% of accelerant; the component C is quartz sand; and the mass ratio of the three components A, B and C is 1:0.25-0.4:4-6. The resin-based spiral spike anchoring agent of the invention realizes the use of the agent in the whole temperature range under the temperature environment of -20 DEG C to +35 DEG C; and when the anchoring agent is used, the requirement can be met by only purchasing one model of product instead of purchasing aplurality of models of products aiming at different temperature ranges. 本发明公开了一种铁路轨枕用树脂基螺旋道钉锚固剂，原料由A、B和C三种组分组成；A组分由80-95％的双酚A型环氧树脂和5-20％的单环氧基团环氧树脂组成；B组分由92-100％的改性脂肪胺和0-8％促进剂组成；C组分为石英砂；A、B和C三种组分的质量比为1:0.25-0.4:4-6。本发明锚固剂实现了在-
