PROBLEM TO BE SOLVED: To provide a construction machine for a diaphragm wall providing uniform and high-quality soil cement with excavation soil sufficiently mixed and stirred over the whole length of a groove hole and providing a favorable working environment.;SOLUTION: This diaphragm wall is so constructed that a hardening material such as cement milk is fed to the ground while excavating the groove hole, the excavation soil and the hardening material are stirred to form the soil cement, and the excavation and stirring works are repeated with the groove holes sequentially adjoined together so as to continue the wall. A rotation drive unit 3 is liftably provided in a leader 2 erected in the front part of the construction machine body 1 and a screw rod 5 attaching a screw blade 5a is attached to the lower end. An excavation device 6 with multiple excavation blades 6b attached ground the outer circumference of an endless chain 6a is provide in the lower end of the screw rod 5.;COPYRIGHT: (C)2003,JPO
