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 worldw

Example Embodiment

[0034] Example 1

[0035] The soil samples were taken from the ruins of the Zhanhua ancient city site in the ancient town of Zhanhua District, Binzhou City, Shandong Province, and the original soil samples were taken for drip reinforcement protection. The selected earthen site reinforcement materials include HYT-1 reinforcement agent, HYT-2 reinforcement agent and HYT-3 reinforcement agent;

[0036] Preparation of HYT-1 reinforcing agent: Take 3-4.5g of nano calcium hydroxide powder and 0.5-1.1g of polyethylene glycol (PEG600) prepared by homogeneous precipitation process induced by surfactant (SDS) in the early stage Disperse in 900ml isopropanol, heat and stir evenly, and ultrasonically shake for 30min to obtain a uniform dispersion system liquid; HYT-1 strengthening agent uses nanometer calcium hydroxide and polyethylene glycol as the main raw materials, and isopropanol as the dispersant ;

[0037] Preparation of HYT-2 reinforcing agent: take 35-45ml methyl orthosilicate, dissol...

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....
