This invention discloses a cement concrete pavement structure for use in vehicular roads, relating to the field of road construction technology. The cement concrete pavement structure includes: a subbase layer composed of graded steel slag; an intermediate base layer composed of cement-stabilized steel slag; a sand cushion layer composed of sand; and a surface layer composed of cement concrete. The subbase layer, intermediate base layer, sand cushion layer, and surface layer are laid from bottom to top. The subbase layer is laid on the roadbed, the intermediate base layer is laid on top of the subbase layer, the sand cushion layer is laid on top of the intermediate base layer, and the surface layer is laid on top of the sand cushion layer. This invention provides a cement concrete pavement structure that can improve the strength of the pavement structure and environmentally treat waste steel slag, thereby improving resource utilization.

The invention belongs to the technical field of preparation of biomass fuels, and particularly relates to a mixed fuel prepared from corn straws and salix mongolica and a preparation method of the mixed fuel. The invention relates to a mixed fuel composed of corn straw and salix mongolica. The mixed fuel is obtained by mixing crushed corn straw and crushed salix mongolica according to a mass ratio of (1-3): 1 and then performing compression molding, the water content of the mixed fuel is 12%-18%; the unit density of the mixed fuel is 0.917 to 1.003 g / m < 3 >; the thickness of the interface transition layer of the mixed fuel reaches 8-15 microns; the pore size of the mixed fuel is smaller than 50 micrometers, and the mixed fuel meets the requirement of third-level fuel and is good in combustion performance.

The application discloses a design method, a hot forming plate and a vehicle, and relates to the technical field of vehicle engineering, wherein, in order to achieve the above-mentioned purpose, the design method comprises the following steps: selecting test design parameters of the first hot forming plate, the second hot forming plate and the third hot forming plate; obtaining first simulation performance parameters corresponding to the test design parameters through simulation software; judging whether the first simulation performance parameters meet a first performance condition; if yes, obtaining welding test parameters to prepare and weld test pieces, and obtaining welding performance parameters corresponding to the welding test parameters; judging whether the welding performance parameters meet the first performance condition; if yes, selecting the test design parameters and the corresponding welding test parameters as actual design parameters. The application effectively improves the lightweight degree and the debugging efficiency of the vehicle, and reduces the production cost.
