Reinforcing agent and reinforcing method for soil site in semi-humid or humid area

Abstract

The invention discloses a reinforcing agent for a soil site in a semi-humid or humid area. The reinforcing agent comprises a HYT-1 reinforcing agent, a HYT-2 reinforcing agent and a HTY-3 reinforcingagent; the HYT-1 reinforcing agent takes nanometer calcium hydroxide and polyethylene glycol as main raw materials, and isopropanol is taken as a dispersing agent; the HYT-2 reinforcing agent takes methyl silicate as a main material, absolute ethyl alcohol is taken as solvent, ammonium hydroxide is added, and heating and stirring are conducted to form a colourless liquid; the HTY-3 reinforcing agent is that a SCA-903 type silicane coupling agent is added to i-butyltriethoxanesilane and absolute ethyl alcohol is taken as solvent. The reinforcing agent has good permeability, and can keep the original appearance of soil surface; so that the soil has suitable mechanical strength and a better weather-resistant ability; the reinforcing agent has better water resisting property, and has a certainresistance to salt corrosion ability, and can better adapt to the environment of the soil site in the semi-humid or humid area.

Description

technical field [0001] The invention relates to a reinforcing agent, in particular to a reinforcing agent and a reinforcing method for earth ruins in semi-humid or wet areas. Background technique [0002] Earth ruins refer to ancient ruins with soil as the main building material, that is, soil and soil-based ruins and relics left over from human activities, including houses, rammed earth foundations, city walls, cellars, kilns, tombs, etc. The cultural heritage of earthen sites is scientific, historical and artistic, but it is also non-renewable. Most of the earthen sites are in the outdoor environment, exposed to wind, sun and rain for a long time, affected by freeze-thaw, air pollution, microbial attack, salt melting and crystallization, vibration, etc., most of the earthen sites are damaged and cracked to varying degrees , Block peeling or even collapsed, some sites are in danger, and scientific protection measures must be taken to properly protect these cultural relics....

AI Technical Summary

Problems solved by technology

[0004] Since the earthen site is directly connected to the earth, the natural soil has low strength and poor water stability

Therefore, even if measures such as adding sheds and coverings are taken, it is difficult to avoid the influence of precipitation, surface water, and groundwater, such as rain erosion stripping, flowing water erosion, gullies, etc.

[0005] The reason why the protection of soil sites in humid environment is a worldwide problem is that they are in a multi-factor uncontrollable environmental system. The engineering geology, hydrogeology and climate environment they are in are different from those of dry soil sites. The disease types and formation of soil sites The mechanisms are also different, and the conservation materials and technologies successfully applied to sites on dry soil cannot be directly applied to the protection of sites on wet soil
