Description
Technical field
The invention belongs to Subgrade soil erosion control technical field more particularly to it is a kind of prevent hillside fields farm road corrode
Construction method and stone dam.
Background technique
For the hillside fields farm road for soil property, general two sides easily are rolled to form rut trace by farm machinery without pumping equipment,
In place of so that hillside fields farm road is become runoff gathering, erosion intensity aggravation in road surface generates erosion groove, not only influences normal agricultural
Machinery is current, and nibbles two sides farmland.
Phase at the end of the 20th century has started the research work of hillside fields farm road erosion, and primary study road erosion both at home and abroad
Mechanism, fewer for the research for how preventing and treating the erosion of hillside fields farm road, data is shown, Liu Yao army etc. has studied 3 kinds of vegetation
Influence of the reforestation practices to soil road slope erosion, Liu Xueying etc. have studied Loess Region hillside Plant Road corrosion protection benefit,
Zheng's generation is clear etc. to have studied loess plateau hillside type of production Plant Road anti-corrosive mechanism and technology, and the research of the above several scholars is substantially
It is all the prevention and treatment that road erosion is inquired into from plant measures angle, Technique Popularizing is not strong, in the biggish region of catchment area, due to
Field road comes that water is big, and water velocity is fast, and scouring force is strong, and road surface erosion control difficulty is larger.
It is typically all non-paved road, that is, agricultural land soil by simple suppression or often in China hillside fields farm road
The farm machinery of property rolls the road to be formed, and road is generally lower than two sides farmland, and since both sides of the road are without gutter, rain
Seasonal rainfall enters road surface by confluence effect, and water flow is rushed naughty road surface formation road surface and corroded, serious to form erosion groove, shadow along road surface
Ring road.Present invention aim to address road surface normal erosions, rush and wash in a pan this ecological environment problem of road surface.
Such as Chinese Patent Application No. are as follows: a kind of road maintenance processing method of the patent disclosure of CN201710139139.8,
It include: the patrol task instruction for receiving first terminal and sending, patrol task instruction includes marking in three-dimensional geographic information system
The inspection process and road component identification sets marked in inspection section mark, Building Information Model BIM, patrol task is instructed and is sent out
It send to second terminal, so that second terminal is instructed according to patrol task carries out inspection, obtains disease integrated information, receive second eventually
The disease integrated information sent is held, according to disease integrated information, the corresponding BIM information of target road component is obtained, according to disease
Integrated information and the corresponding BIM information of target road component carry out Disease Analysis, obtain corresponding disease maintenance plan.In addition,
A kind of road maintenance processing unit and system are also provided.In addition, also providing a kind of road maintenance processing unit and system.But it should
Invent and can not be suitable for the erosion control of hillside fields farm road.
