Description
Technical field
The invention belongs to power transmission and distribution technical field of construction, and in particular to a kind of transmission line of electricity column foot reinforcement means.
Background technique
With the fast development of Chinese economy, the paces of China's electric power development are also constantly accelerated, power grid is also sent out rapidly
Exhibition, network system working voltage grade are continuously improved, and network size also constantly expands.Power grid construction has become in power construction
Main contents, powerful smart grid will be built up comprehensively to the year two thousand twenty.
Due to China territory length and breadth of land, the topographic structure of different regions, weather, temperature differ widely, this is just to China's transmission & distribution
Electrical engineering proposes higher requirement.Since some areas are influenced by dust storm and humid climate, common transmission line of electricity column foot by
Wind erosion, corrosion, cause column foot mechanical property to change, and then keep column foot intensity insufficient, this needs the transmission line of electricity in these areas
The frequent inspection of people and maintenance are wanted, security risk is otherwise likely to occur, even if frequent maintenance, the service life of column foot is also far below
Projected life, so that engineering service life reduction, improves construction cost.
Therefore, the intensity of transmission line of electricity column foot how is improved, there is important research significance.
Summary of the invention
It is an object of the invention to: a kind of transmission line of electricity column foot reinforcement means is provided, it is strong to solve existing transmission line of electricity column foot
Spend lower problem.
The technical solution adopted by the invention is as follows:
A kind of transmission line of electricity column foot reinforcement means, comprising the following steps:
(1) reinforced network is laid in surface of base；
(2) around reinforced network setting grouting template, the grouting template is equipped with the fill orifice at several transverse and longitudinal intervals,
The diameter of the fill orifice is 150mm, and the spacing between the fill orifice is 300-450mm；
(3) self-compacting concrete is perfused from bottom to top from fill orifice；
(4) after self-compacting concrete condensation and when intensity is greater than 5MPa, grouting template is removed；
(5) erosion shield is coated in surface of base；
(6) after basis being embedded to ground, on basis, prominent above ground portion backfills sand-gravel cushion, sand-gravel cushion back-filling in layers,
Every layer is controlled with sample stake, is then tamped with a thickness of 50mm-100mm, lift height；
(7) protective grille is installed around sand-gravel cushion.
Further, the self-compacting concrete of the surface of base with a thickness of 100-200mm, the self-compacting concrete
Slump be greater than 260mm, divergence 600-700mm.
Further, the erosion shield includes epoxy seal coat, polyurethane intermediate coat and acroleic acid polyurethane face
Paint.
Further, the length of the sand-gravel cushion is 1000mm-1500mm, and the width of the sand-gravel cushion is
1000mm-1500mm, the height of the sand-gravel cushion are 200-300mm.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, in the present invention, by carrying out consolidation process and preservative treatment to basis, to improve the intensity of column foot, extend
The service life of column foot, column foot late maintenance cost and frequency is reduced, is used manpower and material resources sparingly, and the construction method technique
Simply, easy to spread, construction cost is lower.
