Soil anti-freezing remediation embedded rod

Abstract

The invention discloses a soil anti-freezing remediation embedded rod, and belongs to the technical field of soil anti-freezing remediation. The soil anti-freezing remediation embedded rod comprises an upper guide rod and a lower buried rod which are distributed up and down, a hydrogen peroxide solution and calcium oxide powder are guided into a reaction preheating ball, the hydrogen peroxide solution is decomposed to generate water and oxygen, water and the calcium oxide powder are in contact to react to generate a calcium hydroxide solution, and the calcium hydroxide solution is diffused into soil along with conveying rods to supplement calcium ions to soil; meanwhile, heat is released in the reaction, so that the oxygen generated by decomposition has a certain temperature, and the oxygen with the temperature is diffused into soil along with the conveying rods and is used in cooperation with heat storage of heat conduction rods; and the temperature of lower soil is effectively increased, meanwhile, oxygen diffused upwards provides nutrients for a microbial agent adhesion layer, the temperature of surface soil can be increased easily, surface soil is not frozen, and capillary water existing in soil is not prone to frost heaving.

Description

technical field [0001] The invention relates to the technical field of soil antifreeze repair, in particular to a pre-embedded rod for soil antifreeze repair. Background technique [0002] In the case of a colder environment, the soil will freeze. In order to prevent the soil freezing from affecting the growth of plants and the absorption of nutrients, the three elements of the frost heaving mechanism of the frozen soil are moisture, soil quality and negative temperature. The fine-grained soil in the soil has the characteristics of frost heaving because its particles are small and its surface area is quite large. Under the interaction of the hydrophilic properties of the soil particle minerals and the electrostatic attraction, a well-developed capillary water is formed, and the capillary water flows from the lower soil to the surface. The phenomenon of redistribution of freezing front accumulation is called moisture migration. As a result of the migration, ice interlayers a...

Problems solved by technology

Therefore, in the prior art, designers generally use non-frost heaving to replace frost heaving soil, but the operation volume is large, and for the planting soil, coarse grained soil, stones, and sand are often not conducive to the planting of vegetation; in addition, the prior art It is also often used to spray hot water into the soil or use electric heating wires for heating, but it is difficult to effectively heat up and thaw the deep soil.
