Description
Technical field
The present invention relates to water and soil conservation fields, particularly a kind of karst sloping field earth's surface soil erosion quantitative collection device.
Background technology
Soil erosion refers to utilization of the mankind to soil, and particularly unreasonable to water and soil resources exploitation and operation make soil
The covering of earth wrecks, and exposed soil is more than the amount that chorizon educates chemical conversion soil, soil stream by hydraulic erosion, number of dropouts
It loses and is lost in and the matrix loss that arrives by the loss of table soil, cubsoil, expose rock eventually.Soil erosion can be divided into water erosion, gravity is invaded
Erosion and wind erosion three types.Soil erosion will also result in the forfeiture and destruction of limiting factors ability, the water of loss
Soil can enter river or reservoir, cause the harm such as siltation, meanwhile, soil erosion can carry away the nutrition such as a certain amount of nitrogen, phosphorus
Substance, these substances may result in nutrient loss and pollution of area source.Just because of this, soil Erosion Research is given both at home and abroad
Certain attention.
At present, be directed to the development of karst earth's surface underground binary space structure, soil layer is shallow, storage capacity is low and
Rock fracture is leakage strong and causes the complexity of soil erosion process, and this area hillside fields earth's surface can effectively be measured by lacking one kind
The method of soil erosion.Therefore, design a kind of device for being capable of quantitative collection karst sloping field earth's surface soil erosion for noise made in coughing or vomiting this
Specially the research of area's soil erosion is of great significance to.
The content of the invention
The technical problem to be solved in the present invention is that providing a kind of karst hillside fields rainwash soil erosion quantifies
The device of collection, it is existing in the art to karst hillside fields earth's surface soil erosion measure so as to solve the problems, such as, it is karst
Hillside fields vegetation restoration and reconstruction and prevention and control of soil erosion provide scientific basis.
It concretely comprises the following steps：
First, establish a karst sloping field earth's surface soil erosion quantitative collection device, including runoff of sloping field slideway, articles holding table, can
Detachable collection soil device, lead-over groove, header tank, telescoping shoring column, water collecting funnel, pvc pipe, elbow, tipping bucket, bearing table and waste water
Bucket.
Runoff of sloping field slideway slant setting, angle of inclination between 10 ° and 70 °, the low one end of runoff of sloping field slideway with
Articles holding table connects, and is supported below articles holding table for telescoping shoring column, and the native device of detachable collection is equipped with above articles holding table one side, can
Detachable collection soil device opposite side is connected with lead-over groove, and lead-over groove slant setting, angle of inclination is between 10 ° and 70 °；Transition
Slot lower end is connected with header tank, and header tank bottom hollows out a circular hole to match with water collecting funnel, and installs gold additional in circular hole
Belong to net, the sundries such as mosquito, fallen leaves is avoided to fall into pvc pipe and whole device is caused to block, be water collecting funnel under metal mesh, catchment
Pvc pipe, another side elbow of pvc pipe are connect under funnel, elbow lower section is tipping bucket, and tipping bucket is mounted on bearing table, under bearing table
Place wastewater barrel in side.
There is a baffle one in articles holding table side, and there is a step structure at middle part, and a side bottom has sliding block there are two guide rail in guide rail.
There is slot in the detachable native device one side of collection, and opposite opposite side has metal mesh, and there are handle in remaining both sides respectively, inserts
Baffle two can be inserted on slot.
Runoff of sloping field cunning 1 and lead-over groove slant setting, angle of inclination are arranged so that between 10 ° and 70 ° and are conducive to soil
It is more thoroughly flowed into water in the native device of collection and captation, avoids water and soil is accumulated in transition apparatus, cause measurement not
Accurate situation occurs.And runoff of sloping field slideway is set to be advantageously implemented runoff of sloping field and smoothly descent flows into articles holding table.
Carrying out the quantitative step of karst sloping field earth's surface soil erosion using above device is：
First, water and soil flow through runoff of sloping field slideway and enter in articles holding table, by being arranged on detachable collection soil dress on articles holding table
The metal mesh put intercepts, and the hole that water can pass through metal mesh flows into lead-over groove hence into header tank, and soil is just by metal mesh
It intercepts, is accumulated in the native device of detachable collection.The stepped setting of articles holding table avoids part water and soil from being deposited on high ladder
On step, so that the collection of soil is more thorough.
2nd, when soil collects the height for reaching slot, insertion and the mating stainless steel shoe two of slot, then using stainless
The detachable collection soil device that steel is filled with hand handle in soil slides out by being arranged on the guide rail of articles holding table, then by guide rail,
One new detachable collection soil device is slipped into articles holding table, is so cycled, and until runoff of sloping field terminates, can realize soil not
It collects disconnectedly.For being filled with the detachable collection soil device of soil, soil can be poured out and cleaned up, can obtain one it is new can
Detachable collection soil device, the soil poured out can draw the loss feelings by rainfall duration somewhere soil by dry check weighing
Condition, at the same the soil after check weighing can be used for measurement it is other it is physical, chemically with biological parameter, be somewhere agriculture
The scientific basis that the offers such as, forestry, ecology can refer to.
3rd, current, by pvc pipe and elbow, are finally reached in the tipping bucket on bearing table, tipping bucket has after water collecting funnel
Scale, and be collected into enough water and just can roll once, the number that tipping bucket rolls finally is counted, and is multiplied by with this number
Water when tipping bucket rolls just, with regard to that can draw the runoff of sloping field amount of this rainfall duration.Runoff of sloping field flows through pvc pipe and curved
Head can realize stably entering in tipping bucket for current, avoid current directly impact tipping bucket and so that tipping bucket be not collected into it is enough
Water just rolls, and causes measurement data inaccurate.It rolls out the water come from tipping bucket to flow into wastewater barrel, these water are for measurement object
Rationality, chemically with biological parameter, provide the scientific basis that can refer to for agronomy, forestry, the ecology etc. in somewhere.
Beneficial effects of the present invention：
1）, function it is more, integrate water and soil collect and detection function.
2）, it is easy to operate, soil need not be destroyed when measuring soil erosion every time, the time has been saved, to be engaged in field
The researcher of work provides facility.
3）, the present invention each component between can flexible disassembly and assembly, be readily transported and install.
4）, the present invention critical component do not limit to being made of stainless steel, can also use plastic production, can not only ensure
Impermeability, and can save money, mitigate quality.
5）, the present invention can be used not only for karst soil erosion measure and research, can be also used for similarly
The place of matter condition has good promotion and application prospect.
