Recently a slurry wall which is continuously excavated in underground should be constructed deeper and wider. For instance the slurry wall of 150m deep was constructed last year. It was difficult to keep the precision of the wall without the computer controlled system. This paper presents a new computer controlled system including a multi data transmission system, a remote controlled system of the excavator, an automatic slurry quality controlled system and an expert system to perform good excavation. We also developed a robot which disconnects a tremi pipe automatically with a sensor to detect the top of the pouring concrete in the slurry wall. The author believes that this system is the first step to the Site Automation.
