Abstract

The invention discloses a fully-enclosed movable type spray maintenance platform. The fully-enclosed movable type spray maintenance platform comprises a door-shaped load-bearing frame, wherein a distribution box is arranged at the front side of the door-shaped load-bearing frame, and a water tank is arranged at the bottom of the distribution box. A PLC is arranged on the front side surface of thedistribution box, an arched supporting frame is arranged at the top of the door-shaped load-bearing frame, and closed rain cloth is arranged at the top of the arched supporting frame. An arched waterspray pipe is arranged on the outer surface of the closed rain cloth, an atomizing spray head is arranged on the outer side of the arched water spray pipe, closed air bags are arranged at the front and rear ends of the door-shaped load-bearing frame, and blast blowers are connected with one ends of the closed air bags. The fully-enclosed movable type spray maintenance platform fully considers tunnel construction working conditions and has the characteristics of high operability and wide application, moreover, the maintenance platform is simple and convenient to operate and high in speed, a remote controller is controlled manually, automatically pulling and walking are achieved, the spray maintenance of second lining can continuously last for a long time, the labor intensity is reduced, andgood working conditions are created for the maintenance of the second lining.

Description

technical field [0001] The invention relates to the field of maintenance equipment for the second lining of tunnels, in particular to a fully enclosed mobile spray maintenance platform. Background technique [0002] With the vigorous development of my country's railway tunnels, the number of long and large tunnels under construction is increasing. For tunnel engineering, due to the wind tunnel effect when high-speed trains pass through the tunnel, there will be greater pressure on the second lining concrete of the tunnel. To ensure To ensure the safety of the train, it is necessary to ensure that the second lining of the tunnel does not fall off even under the condition of strong wind pressure, which means that the concrete of the second lining of the tunnel must not only have sufficient strength, but also meet the requirements of durability. In addition to raw materials and mix ratio, there is another important influencing factor, that is, the curing of concrete. After the c...
