PROBLEM TO BE SOLVED: To provide equipment for constructing a tunnel with the degree of freedom of an adjusting mechanism for the direction of concrete spray nozzle. SOLUTION: This equipment for tunnel construction comprises a main body 3 of the equipment and a boom 31 provided in the equipment, which can be oscillated in both the horizontal and vertical directions relative to the main body 3 of the equipment. Also, an intermediate oscillating portion 33 oscillating in the vertical direction relative to the boom 31 arranged in the boom 31. Moreover, a concrete spraying nozzle 35 is provided, which is provided in the intermediate oscillating portion 33 and is rotatable around a shaft in the longitudinal direction of the intermediate oscillating portion 33 and also oscillates relative to the intermediate oscillating portion 33. In addition, the intermediate oscillating portion 33 is able to oscillate in the horizontal direction relative to the boom 31.
