Freeze-thaw prevention structure for upper roadbed of wetland road and construction method of freeze-thaw prevention structure
The invention discloses a wetland road upper roadbed freeze-thaw prevention structure and a construction method thereof, and belongs to the field of roadbed freeze prevention. Comprising a roadbed; foundation soil is laid at the bottom of the roadbed, and heat preservation layers I are arranged on the two sides of the roadbed. The upper end of the foundation soil is provided with drainage ditches on two sides of the roadbed; the lower end of each drainage ditch is provided with a thermal insulation layer II, and the lower end of each thermal insulation layer II is provided with a drainage tunnel; more than one geotechnical drainage layer is arranged between the two drainage tunnels and at the lower end of the foundation soil; a drainage layer is arranged in the roadbed, and a drainage pipe I is arranged on the side face of the roadbed. According to the device, rising of underground water under the capillary action can be effectively slowed down, then the situation that frost heaving occurs when the temperature is low in winter, and road surface swelling is caused is avoided, the drainage pipe I is communicated with the connecting pipe, the drainage effect is guaranteed, meanwhile, the drainage pipe I is prevented from being communicated with the outside, and the service life is prolonged. Therefore, cold air in winter is prevented from entering the roadbed through the drainage pipe I, and the temperature in the roadbed is prevented from being reduced.
一种湿地道路上部路基防冻融结构及其施工方法，属于路基防冻领域。包括路基；路基的底部铺设有地基土，路基的两侧设有保温层Ⅰ；地基土的上端位于路基两侧的位置上设有排水沟；每个排水沟的下端设有保温层Ⅱ，保温层Ⅱ的下端设有排水坑道；两个排水坑道之间且位于地基土下端的位置上设有一层以上的土工排水层；路基的内部设有排水层，且在其侧面设有排水管Ⅰ。本发明不仅能有效减缓地下水在毛细作用下上升，进而避免冬季温度较低时发生冻胀，造成路面臌胀的情况发生，而且将排水管Ⅰ与连接管连通，保证其排水效果的同时，防止排水管Ⅰ与外界连通，进而避免冬季冷空气通过排水管Ⅰ进入路基内部，导致路基内部温度降低的情况发生。
