Overhead transmission line grounding grid non-excavation construction method

Abstract

The invention relates to an overhead transmission line grounding grid non-excavation construction method. Through a horizontal directional drill, from retesting on a construction zone and a surrounding environment before drilling to procedures such as drilling guiding, grounding radial laying out, fixing and grounding radial back leading, laying of a grounding device is completed, safety is high, and laying working efficiency can be greatly improved. When geological conditions are met, the project time limit needed for grounding device laying can be greatly shortened, a construction process is safe, and accidents can be avoided. From economic benefit, currently, the lease expense of equipment is high and is much higher than the expense of hand excavation, accordingly economic benefit is not very good, however, non excavation is achieved during a construction process, crop compensation expense is saved, and therefore directional driller laying construction has optimistic using prospect under the current environment that labor cost and crop compensation expense rise gradually, and environment protection requirements are improved ceaselessly.

Description

technical field [0001] The invention relates to a non-excavation construction method for an overhead power transmission line grounding grid. Background technique [0002] At present, the development of my country's power grid has entered a stage of large-scale construction, which poses greater challenges and higher requirements for construction technology, construction capabilities, and construction equipment. Improving the level of mechanization and automation of construction equipment, increasing technological content, improving work efficiency, reducing labor consumption, and maximizing environmental protection have become the development trend of power grid line construction. [0003] Trenchless horizontal directional drilling rig is a construction machine for laying various underground utilities (pipelines, cables, etc.) without excavating the ground surface. And oil pipeline laying construction, suitable for sandy soil, clay, pebbles and other ground conditions, and ca...

Problems solved by technology

This construction method is relatively backward, with high labor intensity, low work efficiency and high cost; at the same time, the damage to the ground surface and vegetation is not conducive to environmental protection, and it also increases the burden of compensation costs, which brings difficulty in peripheral coordination and is not conducive to the smooth progress of the project. conduct
