Consolidation agent and reinforcement method for soil ruins in semi-humid or humid areas

Abstract

The invention discloses a reinforcing agent for soil ruins in semi-humid or wet areas, including HYT-1 reinforcing agent, HYT-2 reinforcing agent and HYT-3 reinforcing agent; the HYT-1 reinforcing agent is made of nanometer calcium hydroxide, polyethylene Diol is the main raw material, with isopropanol as the dispersant; the HYT-2 reinforcing agent uses methyl orthosilicate as the main raw material, takes absolute ethanol as the solvent, adds ammonia water, heats and stirs to form a colorless liquid; HYT‑3 hardening agent is to add SCA‑903 silane coupling agent to isobutyltriethoxysilane and use absolute ethanol as solvent. The invention has good permeability and can maintain the original appearance of the soil surface; makes the soil have suitable mechanical strength and better weathering resistance; has better water resistance and certain salt corrosion resistance, and can be more It is well adapted to the environment of earthen ruins in semi-humid and humid areas.

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
