Problems solved by technology

This kind of grounding resistance reducing material has the following disadvantages in the actual construction of the transmission tower grounding project: 1. The project cost is high and the construction is difficult: the use of traditional materials is very large. Generally, the use of a single tower pole is between 3 and 2 4 tons, and because the foundation pit of the tower pole on the construction site is deep, a large amount of earthwork needs to be backfilled...

preparation example Construction

[0037] The preparation method of reinforcing agent of the present invention, concrete steps are as follows:

[0038] In the first step, take non-water-absorbent resin raw materials c, d, and e 50 each WT %; mix c, d, e raw materials, and stir evenly for 10 minutes to make them evenly mixed;

[0039] In the second step, take water-absorbent resin raw materials a and b each 100 WT %, mix a and b raw materials, and then mix a and b mixtures into the mixed raw materials in the first step, and stir again to make them evenly mixed;

[0040] In the third step, add non-water-absorbent resin raw materials c, d, and e to the mixed raw materials obtained in the second step. 50 WT %, stir evenly to obtain the product of the present invention after uniform mixing.

Embodiment 1

[0041] Embodiment 1: A grounding enhancer, including: a, modified starch superabsorbent resin; b, polyethylene and high water expansion resin; c, 150-200 mesh aphanitic graphite powder; d, calcium-magnesium-based bentonite ; e, aluminosilicate cement; the ratio of the raw materials by weight is: a, modified starch superabsorbent resin 8.5 WT %; b, polyethylene and high water expansion resin 13 WT %; c, 150-200 mesh aphanitic graphite powder 36 WT %; d, calcium-magnesium-based bentonite 28 WT %; e, aluminosilicate cement 6 WT %;

[0042] According to the above components and weight fractions, through the dry powder mixer, add about 50 WT % of non-water-absorbent resin raw materials c, d, e are evenly stirred and mixed for 10 minutes; then add 100 WT % Water-absorbent resin raw materials a and b are stirred evenly, and finally add 50 WT % non-water-absorbent resin raw materials c, d, e are uniformly stirred and mixed uniformly to obtain this product;

Abstract

The invention discloses a ground strengthening agent, which is characterized by consisting of the following components in percentage by weight: a. 8.5-12WT% of modified starch super absorbent resin; b. 13-17WT% of polyethylene and high water swelling resin; c. 36-45WT% of cryptocrystalline graphite powder of 150-200 meshes; d. 28-35WT% of calcium-magnesium bentonite; and e. 6-10WT% of silicate cement. The ground strengthening agent disclosed by the invention is specifically applicable to electric system power transmission pole grounding engineering under a high earth resistivity geological environment and an extreme drought geological environment.

Description

technical field [0001] The invention relates to a grounding enhancer; in particular, it relates to a grounding enhancer specially used in grounding engineering, and is especially suitable for grounding engineering in high soil resistivity geological environment and extremely arid geological environment. Background technique [0002] Traditional grounding engineering materials for power system transmission tower pole grounding engineering mainly use physical resistance-reducing materials such as graphite and conductive cement to reduce the power frequency grounding resistance of the grounding grid. This kind of grounding resistance reducing material has the following disadvantages in the actual construction of the transmission tower grounding project: 1. The project cost is high and the construction is difficult: the use of traditional materials is very large. Generally, the use of a single tower pole is between 3 and 2 4 tons, and because the foundation pit of the tower pol...
