透气防水树脂对泥岩土壤防蚀效果的改善

 以透气防水树脂(KMCO-955)作为裸露边坡喷植材料为题,将其应用于泥岩土样表面作为土壤防冲保护层,并以人工模拟降雨器模拟在不同坡度、降雨强度与喷洒药剂浓度之情况下,探讨透气防水树脂对土壤侵蚀量、浸润渗漏水质与土壤硬度的影响。试验结果显示:喷洒透气防水树脂的土壤侵蚀量确实明显减少,其防冲效果佳;采取浸润渗漏水质检测无明显变化,其胶化反应后,并不容易释出化学物质。当喷洒浓度太高时,不仅工作度变差,且经济损失较大;而浓度太低时,因泥岩土壤表面容易龟裂,因此受到雨滴打击会产生破裂。

Improvement of ventilative and watertight resin applied on the erosion control for mudstone soil

This research was concentrated on the soil sampling and laboratory experiment of soil erosion control by means of rainfall simulator with different variety of rainfall intensity attacking the soil surface from mudstones. According to the soil erosion test by rainfall simulating, the quantity of soil losses with different cementation ratios of ventilative and watertight resin were made through the period of the study. Also, the soil hardness, soil reaction and electrical conductivity have been executed by using these remolded soil samples. All soil losses resulted from rainfall simulating test indicated that ventilative and watertight resin cementing chemical treatments can reduce soil erosion exactly, and the ranges of concentration can give a better guideline for conducting ventilative and watertight resin used to reduce soil erosion at the mudstone areas. But it still need more tests for this chemical stabilization treatment on the relationship of slope protection and vegetation growing.
