Construction Case: Injection Work

Injecting a solidifying agent into the voids of sandy soil! Introducing a method to improve it into a stable ground.

"Injection" is a method of improving sandy ground by injecting a solidifying agent (chemical solution) into the voids of the soil to create a stable foundation. First, a survey is conducted to check for any obstacles, and the construction site is marked. A boring machine is set up, and while supplying drilling fluid (chemical solutions A and B), the drilling rod is pressurized and injected to drill to the specified depth. In the first injection, a quick-setting type of chemical is used to fill large voids in loose sand layers and cohesive soil sections, preventing the injected chemical from diffusing or escaping from the injection site. In the second injection, a medium-setting to slow-setting type of chemical is used to permeate and inject into the smaller voids of sandy ground that contain a significant amount of medium to well-compacted sand layers and cohesive soil, solidifying the ground as a whole. Once the specified injection amount for one stage is reached, the process moves to the next stage, and after repeating this for all stages, the chemical solution is replaced with water to fill the injection holes while withdrawing the rods. *For more details, please refer to the related link page or feel free to contact us.*
