Abstract

The invention discloses a road tunnel portal segment flood discharge model test apparatus. The apparatus comprises a main body support system capable of adjusting a longitudinal slope, a road plate assembly arranged on the main body support system, and a water circulation system used for supplying water to the road plate assembly. According to the invention, the road tunnel portal segment flood discharge model test apparatus can satisfy the demand for flood discharge research of a road tunnel portal segment, provides a test base for scientific research work and theoretical research, provides a basis for design of a road tunnel flood discharge system and parameter values, ensures reasonable and effective design, reduces or prevents damage caused by a heavy rain to a tunnel and even a road traffic system and guarantees smooth and safe operation of the road tunnel under the condition of the heavy rain.

Description

technical field [0001] The invention relates to the field of disaster prevention and mitigation of highway tunnels, in particular to a model test device for flood discharge at the entrance section of highway tunnels. Background technique [0002] Under the new characteristic rainstorm conditions, rainwater tends to collect at the entrance of the highway tunnel and pour into the tunnel hole. The tunnel waterproof and drainage system cannot drain the water in the walking area in time, resulting in the tunnel being flooded. However, people do not pay enough attention to the frequent flooding of road tunnels under heavy rain conditions. In order to solve individual problems, they only increase the size of drainage facilities, without considering the overall structural transformation. In order to prevent the tunnel from being flooded, it is necessary to establish a flood discharge system at the entrance of the highway tunnel to discharge a large amount of rainwater poured into th...
