Frost heaving prevention structure for water-rich stratum roadbed
The embodiment of the invention provides a frost heaving prevention structure for a water-rich stratum roadbed. The frost heaving prevention structure comprises a hydrophobic waterproof layer, a geotechnical drainage layer and a drainage ditch; the hydrophobic waterproof layer is of a U-shaped groove-shaped structure within the range of foundation soil below a roadbed; the geotechnical drainage layer is laid on the lower portion of the roadbed and evenly distributed in the longitudinal direction of the roadbed; the drainage ditch is arranged above the foundation soil and used for draining excessive water in the roadbed body; and the thickness of the hydrophobic waterproof layer is designed according to the water level and the pressure bearing condition of local underground water, and the hydrophobic waterproof layer can contain a roadbed and drainage ditches located on the two sides of the roadbed in the width direction and extend to the designed height in the vertical direction. The water-rich stratum roadbed frost heaving prevention structure provided in the embodiment of the invention can block an underground water supply channel in the roadbed frost heaving process and rapidlydischarge roadbed moisture, and is simple in structure, convenient to construct and environmentally friendly in material selection.
本发明实施例提供了一种富水地层路基防冻胀结构，包括：憎水性防水层、土工排水层和排水沟；憎水性防水层在路基以下地基土范围内呈U形槽状结构；土工排水层铺设在路基下部，沿路基纵向均布铺设；排水沟设在地基土上方，用于排出路基本体内多余水分；其中，憎水性防水层的厚度根据当地地下水水位和承压情况进行设计，憎水性防水层在宽度方向上可容纳路基及位于路基两侧的排水沟，在竖直方向上延伸至设计高度。本发明实施例提供了一种富水地层路基防冻胀结构，可阻隔路基冻胀过程中的地下水补给通道，快速排出路基水分，且结构简单、施工方便、选材环保。
