Sludge Treated With Soil Stabilization System, Directly Turning Waste Into Treasure!

Sludge is a soft soil with a natural water content greater than the prevailing limit and a void ratio greater than 1.5. It is generally gray-black, with low mechanical strength, strong compressibility and poor bearing capacity. If there is sludge in the foundation, it is easy to cause the building to sink, so the sludge needs to be treated before construction.
Although most of the sludge land is avoided during project planning, there are still many situations that cannot be avoided, so we can only find another way to deal with the sludge to meet the requirements of subsequent construction. So how to deal with sludge efficiently and economically?

Most of the traditional treatment methods are dredging and replacement. The construction team used an excavator to dig out the sludge from the site, and then replaced it with gravel at the original location. The problem with this method is, where should the excavated sludge be stacked? How to avoid the secondary pollution problem during the stacking process? How should these sludges be treated later? All kinds of problems need to be solved properly, and the crushed stone used for replacement also needs to be purchased separately, which is another cost.

In the continuous exploration and discovery, a brand-new sludge treatment method entered the field of vision of the construction team. This technology, called Soil Stabilization System, uses soil solidifier to directly act on the sludge to solidify the sludge in situ to form a new composite and stable base. Compared with the commonly used sludge that is excavated and then transported and stacked, the on-site solidification of sludge realizes local material acquisition, turning waste into treasure, and has the characteristics of convenient construction, short construction period, low cost and stable solidification effect.

The soil stabilization system consists of material tanks, control center and power mixer. The material tank is used for solidifier raw materials, and the control center mixes the raw materials according to the preset ratio to synthesize the solidifier, and then conveys it to the front power mixer through the hose. The power mixer is installed on the excavator and driven by the hydraulic system of the excavator. The solidifier is sprayed from the nozzle of the stirring head, enters the sludge, and is fully mixed by the power mixer, and a series of physical and chemical reactions occur to achieve the purpose of solidification.
