Active cooling structure for permafrost roadbed in aeolian sand area and construction method
The invention discloses a permafrost roadbed active cooling structure in an aeolian sand area and a construction method, the permafrost roadbed active cooling structure comprises a natural foundation, a block stone interlayer and obliquely inserted heat pipes, the natural foundation is an expressway roadbed in the aeolian sand area; the longitudinal section of the block stone interlayer is in an inverted T shape, the lower portion of the inverted T shape is a transverse block stone layer, the upper portion of the inverted T shape is a vertical block stone layer, and the transverse block stone layer is laid on the natural foundation; the vertical block stone layer is vertically arranged in the middle of the transverse block stone layer in the transverse direction, and the trend of the vertical block stone layer is along the trend of the expressway; the vertical block stone layer is used as a middle isolation zone; the inclined insertion heat pipes are V-shaped pipe bodies with two closed ends, and liquid ammonia is filled in the inclined insertion heat pipes; the included angle of the V-shaped pipe body is an obtuse angle, and two arms are an evaporation section and a condensation section respectively. By adopting the cooling structure, the problem that the permafrost structure protection efficiency is insufficient due to the fact that permafrost and aeolian sand below the wide highway roadbed in the permafrost region are protected is solved.
本发明公开了一种风积沙区域的多年冻土路基主动降温结构及施工方法，包括天然地基、块石夹层和斜插热管，其中：天然地基，为风积沙区域的高速公路路基；块石夹层，其纵切面为倒T形，其中：倒T形的下部为横向块石层，上部为竖向块石层，横向块石层铺设在所述天然地基上；竖向块石层竖直设置于所述横向块石层的横向方向上的中间，其走向沿着高速公路的走向；竖向块石层作为中间隔离带区；斜插热管，为多个，各斜插热管均为两端封闭的V形管体，管内充填有液氨；V形管体的夹角为钝角，两臂分别为蒸发段和冷凝段。采用该降温结构解决了保护多年冻土区宽幅高速公路路基下方多年冻土和风积沙引起的保护多年冻土结构效能不足的问题。
