Description
Technical field
The present invention relates to the electric conducting material technical field, particularly a kind of resistance-lowering material that is used for deep-well grounding device construction, Main classification number is H01B1/06.
Background technology
In high soil resistivity or because of limited zone, region, in order to reach the safety ground resistance value of design, the method that adopts usually is to the developing in depth and breadth of zone, just the deep-well grounding technology of the frequent use in the earth work now.
One type of resistance reducing agent is used for earthing device, be wrapped in around level and the vertical grounding electrode, the composite material that reduces the earth resistance function can be arranged.Because the resistivity of itself is very low, and the contact area increase, the contact resistance between electrode and soil can effectively be reduced.Resistance reducing agent is widely used on the earthing device of transformer and distribution station, power plant and industrial civilian installation, is especially also often using aspect the deep-well grounding technical field.
In deep-well grounding construction, traditional resistance reducing agent needs more (the general ratio: resistance reducing agent: water=2:1) of water in the process of sizing mixing; And water, material layering can appear in the short period (general 2 hours); Occur resistance reducing agent " bridging " during the backfill well, can not fill the ground connection well fully, cause earth resistance to be higher than design load; Because layering causes mobile variation, carry the problem of bringing also for high-pressure pump equipment simultaneously.
The tradition resistance reducing agent not only brings waste owing to do not have set retarder, slurry just can solidify (general 4 hours) very soon in construction.Cause flowability, permeability variation owing to solidify, cause earth resistance can not reach minimum.
To reduce the resistance requirement in order reaching, in engineering, often to have only the quantity that increases deep-well, at this moment have to again consider the electric shield factor between the deep-well, cause direct expense of project with significantly increasing with improvement expenses.Therefore improve the workability of backfill filler, the resistance-reducing efficiency that improves individual well has just become the technical problem of needing solution badly of earth work construction.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of deep-well to fall the resistance filler, and this deep-well falls the resistance filler and is particularly suitable for deep-well grounding, has characteristics such as water consumption is few, perfusion convenience, monomer resistance-reducing efficiency height, has solved the problem that exists in the prior art.
For solving above-mentioned technical problem, the present invention adopts following technical scheme:
The resistance filler falls in a kind of deep-well, and the described resistance filler that falls mainly is made up of following components in weight portions:
