Method for greening discarded soil from mountainous transmission line pole tower foundation construction

Abstract

A method for greening discarded soil from mountainous transmission line pole tower foundation construction comprises the following steps of: S1, selecting a lower side slope (2) of a pole tower foundation (shortened as a tower foundation) (1) as a discarded soil stacking position; S2, removing stones and all other impurities on a slope surface of the discarded soil stacking position, particularly removing growing plants so as to prevent an adverse slope after the plants on which soil is stacked die; S3, forming a gentle slope zone soil-covering layer (3) by the stacked discarded soil, wherein the thickens of the discarded soil gentle slope zone soil-covering layer is larger than 30cm but smaller than 200cm, the stacking gradient is determined on the basis of non-slipping of a saturated discarded soil side slope (3); S4, building a drainage ditch (4) along the edge of the discarded soil slope and building a reservoir (5) on the bottommost part of the drainage ditch so as to form an irrigation system; and S5, modifying the surface of a discarded soil gentle slope zone soil-covering layer which is not thicker than 25cm, fertilizing, and planting a mixed vegetation of shrubs and grass (6) on the gentle slope zone soil-covering layer by a vegetation belt slope protection method. The method for greening the discarded soil from the mountainous transmission line pole tower foundation construction is applicable to positions, where the discarded soil is nearby stacked, near a tower foundation during the mountainous tower foundation construction.

Description

technical field [0001] The invention relates to a method for disposal of infrastructure spoils, in particular to a method for greening disposal of construction spoils for tower foundations (hereinafter referred to as tower foundations) in mountainous areas of power transmission lines. The invention is applicable to the disposal of spoils formed in the construction of tower foundations in mountainous areas of various power transmission lines and tower foundations in mountainous areas of communication lines. Background technique [0002] The implementation rules for the safe and civilized construction of transmission line projects of the State Grid Corporation of China stipulates the disposal of spoil: according to the design requirements, spoil or transport the spoil, and it is strictly forbidden to pile up the surplus soil randomly to avoid damage to natural landforms and vegetation; backfill The remaining soil should be properly disposed of, dumping on the spot is not allow...

AI Technical Summary

Problems solved by technology

[0004] The survey results show that piles of abandoned soil within the foundation protection area will easily lead to uneven deformation of the foundation, the woven bag will be damaged after a long time, and the bag will not work. The cost of surface protection works is very high, so there is no suitable method of stacking the spoil nearby
