Abstract

A multifunctional tunneling machine comprises a cantilever tunneling machine, an arching mounting machine, an onboard jumbolter and an onboard wet spraying machine, wherein the arching mounting machine is arranged above the front part of the cantilever tunneling machine; the onboard jumbolter and the onboard wet spraying machine are both arranged on the side surface of the cantilever tunneling machine. When used for tunneling, the multifunctional tunneling machine performs mechanized operation, simplifies the mounting process of a steel arching, accelerates the anchoring processes of anchor rods or anchor cables, improves the concrete spray quality, and reduces the quantity and labor intensity of operating personnel. Moreover, the multifunctional tunneling machine is ideal tunneling equipment which is advanced in design, simple in structure, convenient to operate, high in operation efficiency, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a tunneling equipment used in tunnel construction. The equipment has multiple functions such as cutting, anchoring, and wet spraying. Background technique [0002] In the field of tunnel construction, tunnel boring machines can be divided into full-face boring machines (TBM) and cantilever boring machines. [0003] Due to the fully mechanized construction, the full-face tunnel boring machine (TBM) has fast construction speed and good safety, but the whole set of equipment is expensive, the construction process is complicated, and the later operation cost is relatively high. [0004] The cantilever roadheader uses the cutting head to cut the tunnel rock during construction. After completing a cutting cycle, the equipment is shut down for tunnel support work. During the support process, the steel arch installation, anchoring and concrete spraying ...
