Abstract
The periodically curved route suitable for general highway, railway and runway features that its road surface shows wave shape and the up-grade and down-grade have a certain gradient and length for best use of gravity. When vehicle or airplane goes down slope, a component of gravity is formed to make it have more potential energy, resulting in saving energy and airplane taking-off or landing quickly.
Description
The present invention relates to a kind of build form of road surface, particularly periodically curved road is built on the road surface, this road is applicable to ordinary highway, speedway, railway and runway.
At present, no matter be highway, railway, or runway, all require the road surface flat more straight more good more, this just considers and makes things convenient for travelling of vehicle, utilizes communications and transportation and can prolong vehicle service life, does not make vehicle reach energy-conservation, economic purpose more fully but the road surface is flat.
Purpose of the present invention is exactly that a kind of periodically curved road is provided in order to overcome the deficiencies in the prior art.
Purpose of the present invention can reach by following measure:
Highway pavement, railway bed, runway are built into the curve road surface, and this curve road surface has periodically, is wavy.
Purpose of the present invention can also reach by following measure:
Road surface itself is straight, and its relative horizontal plane is gradient.Ordinary highway, slope are 1: 30～50, and chamfer length is 100～200 meters.Speedway, slope are 1: 50～100, and chamfer length is 300～500 meters.Railway, slope are 1: 50～100, and chamfer length is 500～800 meters, and runway, slope are 1: 50～100, and chamfer length is 1000～2000 meters.
Ordinary highway, bevel angle are 1 °～2 °.Speedway, railway, runway, bevel angle all are 0.5 °～1 °.
Intersection in the cyclic curve between the inclined-plane adopts the cambered surface transition, and it is R=100 rice that general cambered surface adopts radius of curvature.
Description of drawings:
Fig. 1 is a road surface of the present invention schematic diagram, and wherein L is the length of tilted road surface, and R is the radius of curvature of the crossing transition cambered surface in two inclined-planes, and α is the road surface slope.
Fig. 2 is a runway schematic diagram of the present invention.
The present invention has following advantage:
1, improves transport capacity.
2, improve energy utilization rate, energy-conservation fuel-economizing.
3, improve operating efficiency and the service life of engine.
4, simple in structure, applied widely.
5, improve the safety coefficient of aircraft.
6, improve the tire of aircraft, the service life of brakes and reliability.
7, can make aircraft take off fast, land.
8, reduce runway length, saving floor space.
The present invention is exactly the gravitation that utilizes the earth better mainly based on a kind of consideration, and the partical gravity that produces when utilizing the vehicle descending makes vehicle that a bigger potential energy be arranged, and just can produce bigger kinetic force, so just can reach purpose of energy saving.Take off along descending as aircraft, just can gather way, make aircraft shorten the route that takes off, reduce landing airdrome length.When aircraft landing, prolonging goes up a slope slides, and can shut down in advance.Build the curve road surface and can reach once investment, permanent being benefited can produce huge economic benefit and social benefit.
