A Smart TAM Grouting System for the Shaft and Base Grouting in Bangkok

The Tube-a-Manchette (TAM) grouting is commonly used to construct a waterproof base grouting. It is conducted by injecting grout at a fixed injection rate simultaneously through several grout ports with known spatial coordinates in the ground. The pressure response from the ground can be monitored digitally at each injection port through pressure and flow rate recorders. Also, the recorded data are illustrated in 3D coordinates through computer platforms. Typically, the larger the pressure response from the ground, the better the grouting effect. Finally, compared to the previous experience-based evaluation method, the smart grouting system can interpret the TAM grouting results more systematically and rationally in real-time.
