Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a concrete pump truck suitable for tunnels. Background Art

[0002] With the continuous and rapid development of tunnel construction, my country ranks first in the world in terms of the number and length of tunnels. Due to the influence of geological, environmental and repeated load factors on operating line tunnels, the accompanying operating tunnel diseases are gradually entering a high incidence period, such as cracking, falling blocks and water leakage of lining concrete, which endangers operational safety.

[0003] Traditional tunnel disease remediation often uses manual handling and small non-professional machinery for maintenance. Concrete transportation and pouring usually use concrete tankers and trailer pumps. Due to the long internal length of the tunnel, the length of the pipeline of the traditional pump truck is fixed, and it is impossible to operate at different depths of the tunnel at will. At the same time, due to the strong power of the concrete in the concrete pipe, the concrete pipe outlet needs to be held by someone to prevent the concrete pipe outlet from shaking. Therefore, a special tunnel pump truck with a detachable pump truck main pipe and concrete pipe stabilization equipment is required. Utility Model Content
