WB Stationary soil stabilization plant

Soil stabilization plant, or stabilized soil mixing plant is a equipment specially used to produce stabilized soil. Stabilized soil is a material made by mixing binding materials such as lime, cement, and fly ash with soil, gravel, or other aggregates. This material is widely used in the construction of infrastructure such as roads, bridges, and tunnels. The key functions of the soil stabilization plant include ensuring the smooth progress of project construction, ensuring the service life and safety of the project, reducing the distance of earthwork transportation to reduce project costs, and improving construction efficiency. The main components of the soil stabilization plant include silos, batching system, mixing system, conveying system and electronic control system.

FAQ

Q: What is a soil stabilization plant and what types are it divided into?

A: Soil stabilization plants are divided into mobile and stationary types. Each hopper of the mobile plant can be towed with tires, making it convenient and flexible for transition, but the production capacity is low. The stationary soil stabilization plant requires laying a foundation with concrete and then fixing the equipment on it, but its production capacity is high. The soil stabilization plant  is specially used to mix stabilized soil. It mainly mixes lime, cement, fly ash and other binding materials with soil, gravel or other aggregates.

Q: What are the characteristics of soil stabilization plant?

A: 1) The liner-less twin-shaft forced continuous mixer has strong, fast mixing, long service life, low maintenance cost, and uniform and reliable mixing.

2) The control system adopts a special industrial control system. The weight of the material per unit area is processed by the computer through the sensor with high accuracy.

3) The forced arch breaking device can effectively ensure the batching of lime, fly ash and wet sand (optional).

4) Fully automatic control system, frequency conversion speed regulation, microcomputer fully automatic control of electronic measurement, easy to operate, only one operator is needed.

5) Large-capacity finished product hopper facilitates production continuity.

Q: What are the construction requirements for cement stabilized soil projects?

A: The construction of the cement-stabilized soil structural layer should be organized in seasons with higher temperatures. The daily minimum temperature during the construction period should be above 5℃. In areas with freezing conditions, it should be completed half a month to a month before the arrival of the first heavy freeze (-3~-5℃). When constructing cement-stabilized soil during the rainy season, special attention should be paid to climate changes and the cement and mixture should not be exposed to rain. Construction should be stopped when it rains, but the cement mixture that has been paved should be compacted as soon as possible. When constructing the cement-stabilized soil structural layer, the following regulations should be observed:

1) The soil clods should be crushed as much as possible, and the size of the soil clods should not be larger than 15mm.

2) The proportions should be accurate.

3) Cement should be spread evenly during road mixing construction.

4) Sprinkling and mixing should be even.

5) The thickness and elevation of the base layer should be strictly controlled, and the cross slope of the road crown should be consistent with the surface layer.

6) Compaction should be carried out with the mix at or slightly above the optimal moisture content until the required degree of compaction (minimum requirement) is achieved. 

Q: What is the difference between stabilized soil and concrete?

A: 1) Compositions. Concrete is mainly composed of cement, sand, aggregate and water. Cement acts as a gelling agent, and sand and aggregate act as filling and reinforcing materials. Stabilized soil is composed of soil and other additives. The types of additives can be selected according to project needs. Common additives include lime, cement, slag powder, etc. These additives can improve soil properties, increase compressive strength, and increase shear strength.

2) Principles. Concrete needs to go through a hydration reaction process after construction. Cement reacts with water to form gel. As time goes by, the gel gradually hardens to form a solid stone. Stabilized soil uses additives to change the physical and chemical properties of the soil so that it has good engineering properties. The role of additives can create ionic bonds or hydration cementation between soil particles, increasing the stability and strength of the soil.

3) Applications. Concrete is widely used in construction projects, such as houses, bridges, roads, water conservancy projects, etc. Concrete has good compressive properties and durability and can withstand large loads and deformations. Stabilized soil is mainly used in land improvement and roadbed projects, such as highways, railways, airport runways, etc. Stabilized soil can improve the physical and chemical properties of the soil, improve its compressive and shear strength, and make it suitable for engineering requirements.
