Problems solved by technology

However, compared with the imported organic liquid soil stabilizers, the application of powdery soil stabilizers is obviously insufficient. The main problem is that the amount of mixing is large and the soil stabilization effect is not ideal.

Embodiment 1

[0028] Form soil stabilizer prescription by following weight composition distribution ratio: industrial purity 95% vitriol oil 91kg, turpentine 5kg, phenol ether OP-10 emulsifier 3kg, xanthan gum 0.6kg, carrageenan 0.4kg; Apply this stabilizer to Beijing The sandy loamy soil of the road base of a village in Chaoyang District was consolidated. The optimal water content of the measured soil is 14%, and the actual water content is calculated as 15%; the stabilizer added is 0.02% of the soil weight, and P.O22.5 ordinary portland cement is mixed with 3%; the average daily temperature is 25°C , solidified soil consolidation thickness 200mm, construction area 4000M 2 , the soil liquid limit is 30%, and the plastic index is 9; the road mechanized construction is adopted, and the compaction degree is greater than 97%.

Embodiment 2

[0030] Form soil stabilizer prescription by following weight composition distribution ratio: industrial pure 95% concentrated sulfuric acid 91kg, turpentine 5kg, Tween-80 emulsifier 3kg, sodium carboxymethyl cellulose 0.7kg, guar gum 0.3kg; The stabilizer was used to consolidate the sandy clay on the ground of a parking lot in Chaoyang District, Beijing. The optimal water content of the sandy clay is 12%, and the actual soil water content is calculated as 14%; the curing agent is mixed with 0.02% of the soil weight, and P.O 22.5 ordinary portland cement is mixed with 4%; the daily average temperature is 22 ℃, solidified soil consolidation thickness 100mm, construction area 1200M 2 , the liquid limit of the soil is 26%, and the plastic index is 7; it is compacted with a frog ram, and the compaction degree is greater than 95%.

Embodiment 3

[0032] The soil stabilizer formula is formed according to the following weight composition ratio: 90kg of industrial pure 95% concentrated sulfuric acid, 7kg of turpentine, 3kg of OP-10 emulsifier; apply this stabilizer to consolidate the sandy silt on the ground of a building floor in Daxing, Beijing Processing experiments. Adding stabilizer is 0.02% of soil weight, adding P.O 22.5 ordinary portland cement 5%; solidified soil consolidation thickness 150mm, construction area 800M 2 , the soil liquid limit is 22%, the plastic index is 5, and the optimal water content is 12%; the frog rammer is used for compaction, and the compaction degree is greater than 97%. The strength is 2.25Mpa.

Abstract

The invention discloses a soil chemical stabilizer formula and an application. The formula is characterized by comprising raw material components in parts by weight: 70-93 parts of sulfuric acid, 3-30parts of rosin oil, 1-6 parts of wetting agent, 0.5-1.7 parts of dispersing agent and 0.3-1.5 parts of thickening agent. Soil and the soil chemical stabilizer are stirred evenly for compaction and maintenance under the condition of the optimum water content, wherein the addition amount of the soil chemical stabilizer accounts for 0.01-0.04% of the soil; the soil chemical stabilizer can be used independently, while a little of concrete or lime needs to be added in many cases; the construction of the stabilizer adopts traditional equipment, and the construction method is the same as the conventional process. The soil chemical stabilizer has the characteristics of low cost, excellent performance and environmental friendly materials, and can be widely applied in the fields, such as subgrade construction, water conservancy construction, country roads, temporary sites, low cost road pavements, wall building and brick making and the like.

Description

technical field [0001] The invention belongs to the technical field of chemicals for soil stabilizing treatment, in particular to a chemical for stabilizing and treating compacted soil with optimal water content and its application. Background technique [0002] In the field of building materials, the most widely used and widely used material is soil, which is the basis for supporting our human beings and all biological activities. While enjoying the nature that the soil brings us happiness and hope, human beings also have to face some troubles and disasters, such as strong winds and dust, muddy roads, landslides, foundation collapses, collapse of dams and buildings, mudslides and earthquake etc. Some of these troubles and disasters are inevitable, while others can be reduced through human efforts, and most of these hazards are related to unstable soil. Stabilizing the soil, reducing disasters and preventing damage have long been valued by human beings. Before 2000, our a...
