AI Technical Summary

Technical Problem

Existing methods for producing foamed lightweight soil require multiple mixing devices, leading to large and complex air bubble mixing plants, and cannot efficiently incorporate air bubbles using a single device.

Method used

A system that continuously supplies raw soil, solidifying agent, and water in a predetermined ratio, using a single mixing and transferring device to mix and transfer the materials while adding foam slurry with compressed air, allowing for the production of aerated lightweight soil.

Benefits of technology

The system efficiently mixes and transfers materials to produce aerated lightweight soil using a single device, enabling miniaturization and mobility by being mountable on a truck, while maintaining high strength development efficiency.

Abstract

This invention provides a means to produce air-mixed lightweight soil using a single mixing device and a post-addition of air bubbles, thereby enabling miniaturization of the entire device. [Solution] The manufacturing apparatus 100 for foamed lightweight soil Y comprises a material supply device 10, a mixing and transfer device 20, a foamed slurry manufacturing device 30, and a foamed slurry supply device 40. The material supply device 10 continuously supplies raw soil 1, solidifying agent 2, and water 3 in a predetermined ratio to the mixing and transfer device 20. The mixing and transfer device 20 transfers the mixture 4 of raw soil 1, solidifying agent 2, and water 3 in one direction while continuously mixing it. The foamed slurry manufacturing device 30 produces a foamed slurry 7 by foaming a foaming agent 5 with compressed air 6 to form a slurry. The foamed slurry supply device 40 supplies the foamed slurry 7 to an intermediate position C within the transfer range X of the mixture 4 by the mixing and transfer device 20.
