PROBLEM TO BE SOLVED: To provide a two-liquid mixture rotary injection device using chemical liquids needing no ground device or having a small ground device, capable of enabling construction even in a narrow alley, and allowing a columnar consolidated body to be constructed in a ground.SOLUTION: A two-liquid mixture rotary injection device 10 comprises: a conical front end rotation body 1 including a tip having slanted jetting holes 11 from which two-liquid mixture is jetted, a first horizontal rotation body 3 rotating by receiving a lateral jet flow of A-liquid by blades, and a second horizontal rotation body 4 rotating by receiving a vertical jet flow of B-liquid by blades and formed adjacently to the first horizontal rotation body in the opposite side of the tip; a rod body part 2 including a barrier 5 partitioning the rod body part 5 from an inner chamber of the front end rotation body, and a B-liquid jetting port formed in the barrier 5 and jetting the B-liquid to the blades of the second horizontal rotation body 4; an A-liquid supply system for jetting the A-liquid to the blades of the first horizontal rotation body 3; and a B-liquid supply system connected to a B-liquid jetting port 6. The front end rotation body 1 rotates with respect to the rod body part 2 by supplying two liquids, namely the A-liquid and the B-liquid, and a mixed liquid thereof is jetted from the slanted jetting holes 11 into a subsoil. |
