Conical column type iron tower foundation in plateau frozen soil area
The invention relates to a conical column type iron tower foundation in plateau frozen soil area, which comprises a main column and a bottom plate, the main column is in a cone shape, the bottom end of the main column is connected with the bottom plate, foundation bolts are arranged at the top end of the main column, the bottom plate is in an inverted cone shape, the conical face of the bottom plate faces downwards and is connected with the ground, and the horizontal face of the bottom plate faces upwards and is connected with the main column. According to the iron tower foundation for the plateau frozen soil area, the conical main column and the inverted-conical bottom plate form a stable framework through the steel bars, the stable framework and concrete are poured into a whole, and the tangential frost heaving force of frozen soil on the foundation can be completely or partially eliminated by means of the shape advantage of a conical stand column; meanwhile, the inverted-cone-shaped structure of the bottom plate can partially or completely eliminate the tangential frost heaving force of the frozen soil on the bottom plate, and therefore an iron tower is firmly supported; a conical steel pipe with the smooth surface is adopted, the friction coefficient is low, the problem that the foundation is pulled up and damaged due to frost heaving of frozen soil is effectively solved, the defect that a straight column foundation or an inclined column foundation is prone to being damaged by frost heaving of frozen soil is overcome, and the safety and reliability of the line foundation in the frozen soil area are guaranteed.
本发明涉及一种用于高原冻土地区的锥柱型铁塔基础，包括主柱和底板，主柱为锥形，其底端与底板连接，其顶端设置有地脚螺栓，底板为倒锥形，其锥形面朝下与地面连接，其水平面向上与主柱连接。本发明用于高原冻土地区铁塔基础，锥形主柱与倒锥形底板通过钢筋形成稳定骨架，与混凝土浇筑形成一体，能够依靠自身的锥形立柱体型优势全部或部分消除冻土对基础的切向冻胀力，同时底板的倒锥形构造同样能够部分或全部消除冻土对于底板的切向冻胀力，进而牢靠支撑了铁塔；采用表面光滑的锥形钢管具有较低的摩擦系数，有效降低了冻土冻胀造成基础上拔破坏的难题，避免了直柱基础或斜柱基础易受冻土冻胀破坏的缺点，保证了冻土区线路基础安全可靠性。
