Benefits of soil stabilizer to road engineering

Soil stabilizer is a new type of energy saving and environmental protection material which is synthesized by many inorganic and organic materials. It is mixed with the soil through a series of physical and chemical reaction to change the engineering properties of soil, a large amount of free water in the soil can be fixed in the form of crystalline water, makes the soil micelle surface current reduced, the electric double layer adsorption by micellar thin electrolyte concentration increased, the particles tend to be condensed, volume expansion the filled soil pore, the compaction power, easy to make the solidified soil compaction and stability, thus forming the overall structure, and achieve the pressure density can not be achieved by conventional. The soil after the soil curing agent treated, its strength, density, modulus, deflection, CBR, shear strength and other properties have been greatly improved, thereby prolonging the service life of the road, save the project cost of maintenance, economic and environmental benefits, is the ideal choice of road materials.

Road building with soil stabilizer can replace a large number of lime, cement, fly ash, gravel and other traditional road building materials, saving resources, energy, saving land and so on, and the economic benefits have increased significantly.




1.Reducing construction cost and solidified soil technology is beneficial to save construction funds.
The cost is reduced by 20 – 30% compared with the traditional construction method. The higher the road level is, the more obvious the economic benefit is. Because the material costs accounted for 70% of the cost of engineering construction and installation, and the material transport costs accounted for 70% of the cost of materials. If the composite consolidation soil technology is used to replace the two ash macadam, or cement stabilized gravel is used as the road base, only one material cost can save 40% of the cost of the structure layer. The grade 2 highway is built with traditional materials, and the occupied area is about two acres per kilometer highway, covering an area of about 35000 yuan. Because of the good stability of composite consolidation soil, compared with the traditional lime soil base structure, the subgrade height can be reduced appropriately, and the earthwork quantity of roadbed can be reduced. Taken together, grade 2 road per kilometer can save about 240 thousand yuan of investment. Highway, highway and grade 1 road can even save more than 1 million 350 thousand yuan of funds.

2.Obtain raw material locally, and energy saving.
Using soil stabilizer for road construction, no sand or stone is needed, and the corresponding soil stabilizer can be used only according to soil properties. No matter whether it is aeolian soil, alkaline soil or clay soil, soil sampling can be used for road engineering. Material transportation costs, material field covers can be saved.

3.The construction period is short and the construction equipment is simple.
Mixing soil stabilizer with soil according to certain moisture content, laying in the groove, with more than 8t roller press along with the pressure, rolled subgrade can be available 2 days later in summer, 3 – 7 days later in spring and autumn. There is no need to prepare temporary roads for construction as traditional road construction methods. Labor costs, machinery rental fees, fuel costs will be greatly reduced.

4.Low maintenance cost.
Water softening, volume expansion and erosion are the most harmful to the base. The three main hazards have little effect on the mixed soil of compacted soil stabilizer, so the repair rate is zero.

5.Environmental protection.
Traditional road materials mining destroys vegetation and pollutes environment. Especially lime, cement production consumes large amounts of coal resources and releases a large amount of carbon dioxide greenhouse gases, exacerbating the global greenhouse effect. The technology reduces the use of these traditional cementing materials, saves resources and energy, and is conducive to the protection of the ecological environment.



PARFECT soil stabilization equipment can transfer the soil stabilizer through the air compressor to the mixing head which is mounted on the excavator, and mix with the soil to improve the strength of the foundation.

Treatment of soft soil foundation by high pressure injection method

图片
The method is to use a drilling machine to inject a nozzle pipe into the soil layer. The slurry or water is ejected from the nozzle at high pressure to form a jet stream to destroy the soil layer. When the energy of high speed jet fluctuation was shaped, the dynamic pressure is greater than the strength of soil structure, soil particles stripping down from soil, part of the particles spread out with slurry or water, other soil particles mixed with slurry under the jet impact force, centrifugal force and gravity force, re arrange regularly according to the size of a certain percentage of soil and quality. After the slurry solidified, forming a solidified body in soil, can improve the bearing capacity of the foundation, reduce the settlement, can also improve the effecf of supporting and anti-seepage. It is suitable for foundations of silt, cohesive soil, loess, sandy soil, artificial fill and crushed stone soil. PARFECT soil stabilization equipment can transfer the soil binder t

What is soil remediation

图片
Contaminated soil remediation refers to physically, chemically and biologically transfer, absorb, degrade and transform pollutants in soil, which concentration can be reduced to acceptable levels, or turn toxic and harmful pollutants into harmless substances. Fundamentally, the technical principles for contaminated soil remediation may include: 1.Change the existing form or the mode of combining with the soil of pollutants in soil, reduce the mobility and bioavailability in the environment. 2.Reduce the concentration of harmful substances in the soil. The United States invested nearly $100 billion in contaminated soil restoration in 1990s. The theory and technology of contaminated soil remediation have become the frontiers of environmental science and technology research. The process of soil restoration is quite long, the need to solve the problem of soil pollution, it needs scientists of different disciplines, such as soil science, agronomy, ecology, biogeochemistry, marine scien

Traditional sludge disposal methods

图片
Most of the mud from the small ponds or river in the countryside is directly backfilled to farmlands nearby, which is the most common sludge disposal method used in rural areas in the past few decades. This sludge disposal method has many disadvantages: Some of the sludge has heavy metal pollution, or contains a lot of household waste and construction waste, and farmers refuse to accept it; After returning to the fields, it takes several years to dry. After airing, it needs second treatments. During this period, the fields can not be planted, and the government should pay farmers 1 ~ 2 years’ compensation fees in the form of rent. Cleaned out sludge of coastal rivers, lakes, ponds, and a considerable part of ithave been dumped at sea. In this way, the freight is expensive and tidal, and mud may be washed back inland. In Ningbo, China, the sludge being cleared will be dumped into sea which cost 176 RMB per cubic meter. The river silt in urban areas are often polluted, will usually
