Thermal insulation device for frozen soil roadbed
The invention discloses a frozen soil roadbed heat preservation device, which comprises a heat collection pipe, which comprises a heat absorption section and a heat release section, and the heat release section is inserted into a roadbed from a range between a half slope and a slope toe of the roadbed and is tilted upwards relative to the heat absorption section; the cross section of each position of the heat collection box is in an inverted V shape, the extending direction of the heat collection box is perpendicular to the trend of a roadbed, the interior of the heat collection box is of a hollow structure, and the heat absorption section is inserted into the heat collection box in the extending direction of the heat collection box and located between the tip of the top of the heat collection box and the tip of the bottom of the heat collection box. The heat collecting plates are arranged in the hollow structure and located in the two sides of the heat collecting box correspondingly, one end of each heat collecting plate gradually inclines downwards towards the other end, one end of each heat collecting plate is connected with the heat absorbing section, and the top faces of the heat collecting plates are each coated with a light condensing piece in an attached mode. Solar energy is used for heating the heat absorption section of the heat gathering pipe, then heat is released through the heat release section of the heat gathering pipe, the soil body around the heat gathering pipe is heated, and the frost heaving phenomenon in winter can be avoided.
本发明公开了冻土路基保温装置，包括：聚热管，其包括吸热段和放热段，放热段从路基的半坡与坡脚之间的范围插入路基中，且相对于吸热段向上翘起；集热箱，其各处的横截面均为倒V形，集热箱的延伸方向与路基的走向垂直，集热箱的内部为中空结构，吸热段沿集热箱的延伸方向插入集热箱内，且位于集热箱的顶部的尖部和底部的尖部之间；一对聚热板，其设置在中空结构内，且分别位于集热箱的两侧内，聚热板的一端向着另一端逐渐向下倾斜，且其一端与吸热段连接，一对聚热板的顶面分别贴覆有聚光片。本发明利用太阳能对聚热管的吸热段进行加热，再通过聚热管的放热段将热量进行释放，并加热聚热管周围土体，能够避免冬季冻胀现象发生。
