Road cross section structure of mountainous road

Abstract

The invention discloses a road cross section structure of a mountainous road. A pavement base layer is of a double-wave cross section structure of which the middle part is high and two sides are concave; a concrete road surface layer is cast on the pavement base layer; the top surface of a concrete road is of a streamline groove shaped structure of which two sides are high and the middle part is concave; the pavement base layer and the concrete road surface layer finally form a 'horizontal 8-shaped' cross section structure. The strength of a plate body can be improved by thickening the concrete road surface layer at the bottom of a wheel; due to adoption of ditches in the middle, water can be gathered, so that a soil body is not flashed by the water; due to adoption of a concave transverse slope, a mountain slope side can be prevented from being flashing by surface ponding, and the plate bottom can be prevented from returning flashing, so that a plate can be prevented from being suspended, vehicles can run relatively safely, and a roadbed can be relatively safe; due to adoption of grooves in two sides, the chassis of a vehicle body can be lifted upwards, so that the vehicle body can be protected; as water flowing down from a mountain is gathered on one side or two sides uniformly, original water drainage states of the mountain are not artificially changed, centralized water discharge flashing can be avoided, natural original ecology can be maintained, and a middle water discharge ditch can be clear without sludge.

Description

technical field [0001] The invention relates to the road section structure of mountain roads, especially the road section structure of winding mountain roads in areas with many slopes. Background technique [0002] The cross-section design of the existing highway pavement is generally a rectangular slab. This design is suitable for vehicles to turn, overtake, and pass vehicles at will. The design form requires more concrete, which is an excessive consumption of materials for rural roads and low-grade roads in mountainous areas with single-lane vehicles; once the slab body breaks or the expansion joint leaks in this slab road, it will quickly lead to substratum lamination Bad slopping, even the board body warps and cracks until it cannot be used. [0003] The use of such rectangular plates on winding mountain roads in mountainous areas is more likely to cause the inner side to scour the mountain, causing landslides, and the outer side to scour the slopes, causing the plates ...

[0002] The cross-section design of the existing highway pavement is generally a rectangular slab. This design is suitable for vehicles to turn, overtake, and pass vehicles at will. The design form requires more concrete, which is an excessive consumption of materials for rural roads and low-grade roads in mountainous areas with single-lane vehicles; once the slab body breaks or the expansion joint leaks in this slab road, it will quickly lead to substratum lamination Bad slopping, even the board is warped and cracked until it cannot be used

[0003] The use of such rectangular plates on winding mountain roads in mountainous areas is more likely to cause the inner side to scour the mountain, causing landslides, and the outer side to scour slopes and cliffs, causing the plates to hang, crack and subgrade to collapse; wet and slippery rainy days even cause vehicles to slip out of the road and turn down the cliffs
