Abstract

The invention relates to the field of highway design, and provides a roadbed planning model for highway design, which comprises a base, a water storage tank is arranged at the bottom of the base, a cushion layer, a subbase layer, an upper base layer and a top surface layer are sequentially arranged in the base from bottom to top, a connecting box is arranged at the lower end of the base, and the connecting box is communicated with the water storage tank through a pipeline. The storage water tank is connected with an adjustable rainfall assembly through a water delivery component. A first electric push rod for pushing out the cushion layer and the subbase layer and a second electric push rod for pushing out the upper base layer and the top base layer are further fixed to the base. The model has the beneficial effects that the adjustable rainfall assembly is arranged, and the rainfall amount can be adjusted, so that different rainfall amounts can be simulated, the water seepage amount of a road surface can be simulated, and the road surface can be conveniently planned and designed; by arranging a first electric push rod and a second electric push rod, the corresponding base layer of the pavement can be pushed out of the model for observation, and observation is convenient and careful.

Description

technical field [0001] The invention relates to the technical field of highway design, in particular to a roadbed planning model for highway design. Background technique [0002] The roadbed is the foundation of the road surface, and it is a belt-shaped structure built according to the route position and certain technical requirements. The main function of highway subgrade is to provide necessary conditions for pavement laying and driving operation, and to bear the driving load transmitted from the road surface, and at the same time transmit and spread the load to the depth of the foundation. On the longitudinal section, the roadbed must ensure the elevation required by the line; on the plane, the roadbed is connected with bridges and tunnels to form a complete and continuous line. In civil engineering, subgrade plays an important role in terms of construction quantity, floor area and investment. [0003] Before highway design, the subgrade planning model is generally used...
