The New Polymer Processing Technology Of Soft Rock Slope

With the highway in the country in general, has many problems come one after another in the built highway. The treatment of soft rock slope is always a difficult problem, According to statistics, every year due to slope failure caused by the loss of more than 10 billion. In China, many scholars have begun to study the solution, but the protective effect is still not ideal.This paper relies on the project for the Zhulanjiao of Taishun county to Peng Xi highway project, In the project K6+467.3-K6+597.3 sections is soft rock slope. The height of slope is 50m, divided into five stage excavation, the slope surface is strongly weathered crystal tuff.If hanging net sprayed concrete treatment can effectively protect the slope according to the conventional construction method, but the large area concrete construction affects the ecological aesthetics of expressway construction. This paper summarized the research status os soft rock slope at home and abroad, and the current research situation os curing agent. proposed a new polymer cement-based solidification material in the use of the slope.Based on the research of domestic and foreign scholars, to the main reason for the instability of soft rock slope and the form of expression make an analysis, the curing mechanism of polymer cement curing agent were analyzed. The volume of the new preparation curing agent can directly affect the hydrophobicity, adhesion, water resistance, mobility of the curing agent and so on performance, so through the performance test and test result analysis or summary, ultimately determine the volume of cement.Relying on the project in the original design of the excavation slope is divided into five stages, the first stage and the second stage slope into the bolt to be fixed,this paper through the Slide software to analyze the stability of soft rock slope calculation.The new curing agent spraying construction technology with the conventionalcement slurry spraying has many different, the methods and steps of previous spraying cement slurry, formulated the construction guide to adapt toa new curing agent.
