Intercepting ditch 2 on hills slope 1 and the ridge 3 on hills slope 1 and being located at below intercepting ditch 2 is set, the intercepting ditch 2
Top is provided with the isolation structure 4 for soil, vegetation to be isolated.The isolation structure 4 is using in separation net, segregator barriers
It is one or more.
For vegetation on the grassland of hills mainly based on herbage, herbage root system is poor for the grasping force of soil, in rainfall,
The topsoil on hills grassland is easy to be lost under the action of rain drop erosion.
Using intercepting ditch 2, it can play the role of that water flow is truncated, reduce water flow to the impact forces of soil and reduce water
The soil that stream is taken away, to reduce the loss of soil.According to specific needs, intercepting ditch 2 by the grassland of hills side by side or
Along hills, short transverse is arranged in parallel multiple to enhance the effect shut off.
When 1 gradient of hills slope is greater than or equal to 20 °, the spacing of intercepting ditch 2 and intercepting ditch 2 is 20.29m.Work as the gradient
At 15 °~20 °, the spacing of intercepting ditch 2 and intercepting ditch 2 is 25.50m.When the gradient be 10 °~15 ° when, intercepting ditch 2 with intercept water
The spacing of ditch 2 is 30.61m.When the gradient is 5 °~10 °, the spacing of intercepting ditch 2 and intercepting ditch 2 is 55.71m.When hills slope
When 1 gradient is less than 5 °, the run-off and sediment yield on hills slope 1 are relatively small, thus the slope surface suggestion less than 5 ° without
The excavation of intercepting ditch is changed to construction artificial pasture.
Intercepting ditch spacing the smallest u-turn turning radius mechanical more than or equal to animal husbandry can also be met with this, with guarantee its
Energy consumption is minimum when work, efficiency highest and round-trip number are integer and avoids energy waste.
The soil that 3 lower section of the ridge can be compressed using the ridge 3 can compress the soil of 2 lower section of intercepting ditch using intercepting ditch 2, and
Rainwater and the soil of 2 lower section of the ridge 3 or intercepting ditch is avoided directly to contact, to be beneficial to prevent the loss of the part soil.It utilizes
The ridge 3 also can play the role of stopping in rainfall to water flow to be shunted, to reduce the loss of soil.And can in wind season,
Reduce wind erosion of the wind-force to hills slope 1.
When water flow drives soil to flow downward, obstruction can be played the role of using isolation structure 4, reduce soil in rain
Loss under water souring.
