The inorganic chemistry anchor fission type spike anchor technology takes one kind of concrete tie screw spike new anchor technology, this technology might substitute formerly used the sulfur anchor spike's conventional routes to use in the ordinary railway engineering, might also use in the monolithic concrete track bed high-speed railroad project.Not only the inorganic chemistry cementing agent has overcome the sulfur anchor medicinal preparation inherent weakness, moreover the compressive strength, anti-pulls out the strength, to withhold the moment of torsion and so on major technique target to surpass the sulfur anchor medicinal preparation.Through to the inorganic chemistry chemistry cementing agent physical mechanics performance test research, obtains the inorganic chemistry cementing agent set time to be short, the early strength is high. Has the micro inflation characteristic. May achieve the design requirements in the 1h intensity, the 28d intensity achieves above 100Mpa.The inorganic chemistry cementing agent lasting quality experiment indicated that the inorganic chemistry cementing agent has the fine impermeability to be able as well as the good anti-corrosive performance, in has under the water condition to insulate the spike also to be possible to satisfy the railroad line insulation request.The inorganic chemistry cementing agent hardening body contact surface cohesiveness experiment obtains the twisted steel anchor and the light round anchor differs from the anchor stress causes these two kind of situations to be very big under the limit pulling capacity condition value difference.The fission type spike anti-pulls out the strength and the anchor medicinal preparation compressive strength is proportional the growth, under normal temperature, when the inorganic chemistry cementing agent hardening body compressive strength achieves 40Mpa the anchor pulling capacity may achieve 60KN the request.Through may know the inorganic chemistry cementing agent to the inorganic chemistry cementing agent anchor fission type spike's each performance's research to have the early strength to be high, anti-corrosive, the corrosion good, the craft is simple, the cost inexpensive, safe reliable, the improvement work condition, the cold mix cold construction, do not have the environmental damage, the different local whole year use, overcame the traditional sulfur anchor medicinal preparation to need hot malpractices and so on melting, hot construction, work condition difference, pollution of the environment. Opened a security, the economical, the non-pollution new path for tong the railroad tie bolt anchor, is worth promoting and the application.Through to the inorganic chemistry anchor fission type spike performance study and with the application, has established the one whole set testing method and the tentative data, provides the mentality and the method for this domain's further research, later the establish standards and the examination method will provide the reference and the basis for the country.
