Daily treadmill 10% incline slow speed (4.5km/h) walking 30 to 40 minutes, each time to burn 300 calories.
With an incline of less than 20% (1:5), a person can stand and walk with little discomfort. When the slope is less than 10% (1:10), people can walk on it and feel like they are walking on the ground. Slope less than 5% (1:20), has been the minimum slope of the disabled wheelchair. So small 10% are suitable, can be selected according to the conditions.
"Urban residential planning and design specifications (GB 50180-93)" 8.0.3.1 Article: Roads in residential areas should meet the following longitudinal slope control indicators; motorized road maximum longitudinal slope should be less than 8%, the maximum longitudinal slope of the non-motorized road should be less than 3%, the maximum longitudinal slope of the walkway should be less than 8%. If beyond this provision can be set up steps, generally is greater than 15 degrees to set up steps.
Building entrance ramp width should not be less than 1.20m, indoor walkway ramp width should not be less than 1.00m, outdoor access ramp width should not be less than 1.50m. building entrance and indoor ramp slope should not be greater than 1/12, outdoor pedestrian access ramp slope should not be greater than 1/16.
Maximum longitudinal slope of the various levels of highway values:
Plain microhills (%) Mountain heavy hills (%)
High speed 3 , 5
Grade 1 4 , 6
Grade 2 5 , 7
Grade 3 6 , 8
Grade 4 6 , 9
For the purpose of drainage, the roadway surface and the shoulder should be made with a certain slope,i1 and i? indicated. It varies with the smoothness of the pavement, if the concrete pavement i1 is 1% - 1.5%; asphalt pavement i1 is 1.5% - 2.5%; i?is generally larger than i1 1% - 2%.?
