Method for installing overhead transmission line supports on permafrost soils
A method for installing pile foundations for power transmission towers or the like in different types of soil prone to frost heaving provides piles with bearing capacity against horizontal loads, reduced labor content and installation cost, and increased reliability against the impact of frost heaving forces of the soil on the pile. A casing pipe is driven in and then the pile is inserted into it, while installing rigid elements on the pile shaft by welding. When driving the pile, when a mark indicating a point of installation for a rigid element reaches the top of the casing pipe, a geometric measurement of gaps is made between the casing pipe and the pile. Based on the measurement, rigid elements are sized and welded in pairs on the opposite side in a vertical plane. The operation of placing and welding is then repeated during the pipe inserting.
