The invention discloses a vehicle for transporting and arranging pipe for pipeline construction, and belongs to the technical field of pipeline engineering. According to the vehicle, a truck tractor head is adopted to be hinged to a flat car, and the truck tractor head is used for towing the flat car to walk and steer, a pipe unloading mechanism is installed on the flat car, pipelines to be installed are arranged on the pipe unloading mechanism, after the vehicle for transporting and arranging the pipe for the pipeline construction transports the pipelines to be transported to the design installation position of the pipelines, the pipelines are automatically unloaded through the pipe unloading mechanism, the situation that special hoisting equipment is used for unloading the pipelines in anarrow tunnel space is avoided, and the construction difficulty is greatly reduced. After the pipelines are unloaded, the two-way control mechanism is started to change the walking direction of the vehicle for transporting and arranging the pipe, so that an operator only needs to operate the vehicle for transporting and arranging the pipe in the forward direction, the vehicle can quickly evacuatefrom a tunnel without turning, the potential safety hazard caused by backing evacuation of equipment in the tunnel is solved, the construction safety is ensured, and the construction efficiency is improved.
