Polymer Cement Composites And Slope Curing Applications

With strongly investment on the developing of western region, the infrastructureconstructions in the west develop rapidly. Since complex terrain of the westernregion, these complex mountainous terrains has cause great difficulties to appear onthe highway design and construction, and stability of soft rock slope is a very difficultproblem, especially the problem of all kinds of soft rock slope curing. Although therewere many research on soft rock slope protection at domestic and international , thesoft rock engineering slope is generally adopted for hanging on shoetree mortar ormortar rubble closed soft rock slope method, it could prevent soft rock slope collapseeffectively, but a far cry from highway construction eco-friendly concept ; nowcommonly used in soft rock slope ecological protection methods focus on to create alandscape effect at the time and the normal growth of vegetation, but can notprevent the erosion and soften of soft rock slope and the overall structure of theinstability problem, A few years later, the ecological protection of the soft rockslope failures often occurs.Rely on the soft rock slope engineering governance of Liu Yi expresswayin Guangxi and on the basis of the full study of the theory and technology of softrock slope protection at domestic and international, it proposed that polymer cementcomposite as a curing agent to solidified the rock slope in order to prevent,weaken or slow soft rock slope softening and disintegration , to achieve greaterlong-term stability of soft rock slope engineering soft rock slope stability controlmethod ,The following research and work for this topic: Prepared polymer cementcomposite curing agent based on the polymer-modified grout principle, to selectpolymer emulsion and in-depth study explores the performance of the effect andmechanism of polymer emulsion on polymer cement composites curing agent. Usingthe scanning electron microscopy to research the microstructure changes in thesoftening process of soft rock, the curing agent on the strength of soft rock isinvestigated further. Compare different magnification scanning electron micrographand used Matlab software analysis, research curing agent curing soft rock samplesurface before and after the shape, internal structure, to link the form and the poreshape and size of change; Finally ,select different sections of the soft rock slope at theconstruction site as a test section, test the new curing agent viscosity, elasticity, permeability and durability, and observe experimental section and non-experimentalsection of soft rock softening to find the most reasonable option and constructiontechnology.
