Anti-settlement system for roadbed in frozen soil area
The invention provides an anti-settlement system for a roadbed in a permafrost region, and relates to the technical field of geotechnical engineering, the anti-settlement system comprises: a plurality of heat dissipation rods inserted at two sides of a highway roadbed; the heat dissipation rod comprises a first section, a second section and a third section which are sequentially connected from top to bottom and are respectively provided with a first cavity, a second cavity and a third cavity; the top end of the second section is slidably connected into the second cavity from the opening in the bottom end of the first section, and the first cavity, the second cavity and the third cavity are communicated with one another to form a liquid storage space; the bottom end of the first section is provided with a plurality of arc-shaped pressing pieces which extend downwards and are arranged at intervals in the circumferential direction, the arc-shaped pressing pieces are connected to the outer wall of the second section in a pressed mode, and outer threads are arranged on the outer walls of the arc-shaped pressing pieces. The heat dissipation rod further comprises a locking sleeve. From top to bottom, the diameter of at least one part of the locking sleeve is gradually reduced, internal threads corresponding to the external threads are arranged on the inner wall of the locking sleeve, and the locking sleeve can inwards press the arc-shaped pressing piece on the outer wall of the second section by rotating the locking sleeve.
本发明提供了一种冻土区路基防沉降系统，涉及岩土工程的技术领域，包括：插设在公路路基两侧的多个散热棒；散热棒包括自上而下依次连接的第一段、第二段和第三段，分别具有第一腔体、第二腔体、第三腔体；第二段的顶端自第一段的底端开口滑动连接于第二腔体内，且第一腔体、第二腔体和第三腔体彼此连通呈储液空间；第一段的底端具有向下延伸且沿周向间隔设置的多个弧形压紧片，弧形压紧片压接在第二段的外壁上，弧形压紧片的外壁上具有外螺纹；散热棒还包括锁紧套；自上而下，锁紧套上至少具有一部分的直径逐渐减小，锁紧套的内壁上具有与外螺纹对应的内螺纹，通过旋转锁紧套能够使锁紧套将弧形压紧片向内压紧第二段的外壁上。
