A dual slurry injection pipe end head mixing device belongs to the field of civil engineering. A slurry injection pipe connector is connected with a slurry mixing chamber; a first mixer is connected between the slurry injection pipe connector and the slurry mixing chamber; one end of a slurry injection pipe is connected with the slurry mixing chamber, and the other end of the slurry injection pipe is connected with an injection sprayer; a second mixer is connected between one end of the slurry injection pipe and the slurry mixing chamber; a check valve steel ball, a compression spring and a slurry stirrer are connected to an inner hole of the slurry injection pipe; slurry outlets are formed in the periphery of the slurry injection pipe. The dual slurry injection pipe end head mixing device has the benefits that via adding the slurry mixers, the slurry stirrer, the injection sprayer, the uniform slurry outlets and the like, fully mixing of dual slurry is achieved, and the situation that sediment, stone and the like enter the inner pipe to cause pipe blocking since the slurry is uniformly spread is realized.
