Distinctive feature
1. Form a high-quality water-stop plug
It improves the soil ground with high groundwater content and low adhesion, suppressing discharge blowout and ground loosening.
2. Salt resistance
Even with groundwater containing salts, it forms a high-quality seal plug without being affected by the salt, suppressing discharge blowout.
3. Requires a small amount and makes the work easier
It is an agent that can achieve high effectiveness with a small amount, reducing labor during construction and offering excellent cost-effectiveness.
The mechanism of blowout
When there is a high amount of groundwater, the slurry may separate and compact, preventing the formation of a seal plug, which leads to blowout. As a result, the cutting face pressure is not maintained, causing soil and groundwater to flow into the chamber, potentially leading to ground subsidence.
By injecting this agent at the base of the screw conveyor, it improves the slurry into a good mud-like consistency and forms a seal plug, enabling safe soil discharge. As a result, the cutting face pressure is maintained, allowing for safe excavation.
