一种防止土壤冻胀引起电线杆上拔的结构
摘要：
本发明涉及一种防止土壤冻胀引起电线杆上拔的结构，所述防止土壤冻胀引起电线杆上拔的结构包括：电线杆、套筒、防水层、减阻层；所述套筒设置在电线杆的底端；所述套筒和电线杆设置在防水层内；所述减阻层设置在电线杆的杆根表面；所述套筒由筒体和环罩组成，筒体和环罩固定连接；所述环罩的上端与电线杆之间锐角连接，且环罩的上端与电线杆之间固定连接；所述筒体的下方边缘为刀刃状；所述套筒内部、套筒和防水层之间填充有干燥、夯实的细沙。本发明通过环罩的上端与电线杆之间锐角连接的设置，土壤冻胀对电线杆的上拔的作用力转化为竖直向下的作用力，增大电线杆上拔的阻力，能够很好地克服土壤冻胀引起的电线杆上拔的问题。
摘要（英）：

The invention relates to a structure for preventing telegraph pole upward pulling due to soil frost heaving. The structure for preventing telegraph pole upward pulling due to soil frost heaving comprises a telegraph pole, a sleeve, a waterproof layer and a drag reduction layer. The sleeve is arranged at the bottom end of the telegraph pole, and the sleeve and the telegraph pole are arranged in thewaterproof layer. The drag reduction layer is arranged on the surface of a pole foor of the telegraph pole, and the sleeve is constituted by a sleeve body and an annular cover which are fixedly connected. The upper end of the annular cover is in acute angle connection with the telegraph pole, and the upper end of the annular cover and the telegraph pole are fixedly connected. The edge of the lower portion of the sleeve body is in a blade shape, and the interior of the sleeve and the position between the sleeve and the waterproof layer are filled with dry and tamped fine sand. Through arrangement of acute angle connection between the upper end of the annular cover and the telegraph pole, acting force of soil frost heaving on telegraph pole upward pulling is converted into vertical downwardacting force, resistance of telegraph pole upward pulling is increased, and the problem of telegraph pole upward pulling due to soil frost heaving can be avoided well.
