The invention discloses a maintenance stand for a tunnel. The maintenance stand comprises telescopic base stations, wherein a water tank is fixedly arranged at one end of each telescopic base station;a portal reinforced frame plate is fixedly arranged at the tops of the telescopic base stations; supports are arranged at the top of the portal reinforced frame plate; water delivery branch pipes arearranged on the outer side of the support; waterproof cloth is arranged between the water delivery branch pipes and the supports; airbags are respectively arranged on the outer sides of two ends of the telescopic base stations; blowers are respectively arranged at two ends of the telescopic base stations and are communicated with the airbags by gas transmission pipelines; spraying nozzles are arranged on the surfaces of the water delivery branch pipes; a water pump is arranged at the bottom of an inner cavity of each water tank; and a water delivery main pipe is connected to the end parts ofthe water pumps. The maintenance stand is provided with the telescopic base stations and the portal reinforced frame plate, so that persons and vehicles favorably pass through the middle part of the portal reinforced frame plate, and the occupied space of the maintenance stand in the tunnel is effectively reduced; and meanwhile, the influence on other operations when the inner wall of the tunnel is maintained is also avoided.
Description
technical field [0001] The invention relates to the technical field of road maintenance, in particular to a maintenance platform for tunnels. 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 concrete is poured, if the climate is hot and...
