technical field

The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a tire-type tunnel operation vehicle.

Background technique

With the development of railways in the central and western regions of my country, the construction of new railway lines in these mountainous areas requires more or less tunnel excavation, and the equipment cost of excavating tunnels is relatively high, especially in the continuous construction of long tunnels. To save construction time as much as possible, from the perspective of saving cost and time, there is an urgent need for a professional construction equipment that can meet the requirements of tunnel excavation slag removal, concrete pouring and material transportation in the cave.

The existing tunnel construction equipment is mainly trestle, which is generally used for the construction of special sections such as tunnel entrance, and the auxiliary facilities that can be constructed inside the tunnel are mostly temporary trestle. After years of practice, some problems can be found in this type of trestle, and the construction and operation of tunnel excavation slag removal, concrete pouring and material transportation in the tunnel cannot be realized at the same time. In addition, there is no emergency safety escape channel reserved in the event of a tunnel collapse or collapse accident, and there are certain safety hazards. Due to space constraints in the tunnel, these cross constructions require a construction equipment that can serve multiple functions at the same time.
