铁路路基基床翻浆冒泥病害在我国南方地区的线路是比较多的,有些甚至很严重,影响运输及行车安全。有些工点虽经多次整治,仍不见效果,桂北工点就是其中之一。据国外资料介绍,目前多采用高分子化学材料进行整治,效果较好,故选定桂北工点试用塑料软板做封闭层,配合纵向渗水盲沟进行综合整治。1980年12月,在桂林工务段的积极支持和配合下,当月施工完毕,经1981年雨季迄今现场观察未见泥浆冒出,线路质量良好。现介绍如下: Subgrade bed boring and muddy disease of railways in southern China is more lines, and some even very serious, affecting transport and traffic safety. Although some work sites after repeated remediation, still no effect, work-point is one of the North of Guangxi. According to the introduction of foreign materials, the current use of polymer chemical remediation, the effect is better, so the selection of the pilot site in northern Guangxi plastic laminates to do with the closure layer, with the vertical blind seepage water for comprehensive treatment. In December 1980, with the active support and coordination of the public works section of Guilin, the construction of the month was completed. No mud emerges from the observation of the rainy season so far in 1981, and the quality of the line is good. Now introduced as follows:
