High-underground-water-level silty subgrade filling technology
The invention relates to the field of highway subgrade engineering, in particular to a high-underground-water-level silty subgrade filling technology, which adopts certain technical measures to treata subgrade base and realize normal filling of the subgrade when the subgrade is a powdery or silty base with high underground water level and is even soaked in water, and the subgrade base is in a soft foundation state. The problem that filling is difficult when a subgrade is under the geological conditions of having high water level and being silty is solved. By means of the method of layered filling of superfine sand, formation of a base platform, edge covering of clay on the two sides and arrangement of a drainage pipe at the bottom, base treatment of a subgrade is achieved, and normal filling of the subgrade on the upper portion is achieved. The technical method provided by the invention is easy to operate, low in cost, free of environmental pollution and quick in effect.
本发明涉及公路路基工程领域，特别地，涉及一种高地下水位粉砂质路基的填筑技术，当路基为粉质、粉砂质基底，高地下水位甚至浸水，路基基底为软基状态时，采取一定的技术措施，对路基基底进行处理并实现路基正常填筑，解决了路基处于高水位、粉砂质地质条件时填筑困难的问题，本发明利用特细砂分层填筑、形成基层平台，两侧黏土包边，底部设排水管的方法，实现路基的基底处理、并实现上部路基的正常填筑。本发明提出的技术方法，易于操作，成本低，无环境污染，见效快。
