Description
Technical field
The utility model relates to soil loss monitoring equipment technical field, is specially a kind of dynamically runoff and sediment automonitor.
Background technology
China is one of the most serious country of soil erosion in the world, and the extent of injury of soil erosion, development trend, coverage all need to be grasped by the monitoring means of science.Science, system, effective soil loss monitoring and forecast can provide vital data supporting for China's water and soil conservation decision-making.
Since 2007 the whole nation start, implement one, the second stage of soil and water conservation monitoring network and Information System configuration engineering, complete Ministry of Water Resources's water and soil conservation value center, each basin water-soil keeps monitoring center station, the construction of water and soil conservation value master station of each provinces, autonomous regions and municipalities and city under the jurisdiction of the provincial government's water and soil conservation value substation and perfect, specify that the function of mechanism for monitoring at different levels, Contents for Monitoring, be equipped with monitoring facilities, for guarantee soil and water conservation monitoring work science, orderly, long-actingly carry out the system of providing and technical guarantee.
The improvement etc. in the research of Soil Erosion, the layout of measures, soil erosion region all needs science, accurately Monitoring Data as the basis of theory and practice.In addition, along with the quickening of China's modernization construction paces, the artificial Newly-added Soil Erosion that all kinds of production and construction project causes also becomes the important factor in order that soil erosion produces, the soil erosion that natural conditions, mankind's activity etc. cause, all needs water and soil conservation value mechanism to remove record by scientific and effective monitoring method, means and equipment, grasps and analyze in its quantity, scale, Changing Pattern, trend, the extent of injury, coverage etc.
Water and soil conservation community runoff and sediment observation experiment is the important channel of Erosion and soil and water conservation benefit in survey region, is also the important content of whole nation second phase soil and water conservation monitoring network construction plan.The infrastructure of water and soil conservation district monitoring comprises community of catchmenting, afflux groove and afflux pond (or afflux bucket) etc., if the patent No. is the district soil erosion observation barrel of a kind of improvement disclosed in the Chinese utility model patent of 200820062767.2.Sight gauge measuring appratus mainly comprises rain gage bucket, device for fetching water from, baking oven, balance.
(1) traditional runoff observation on plots method ultimate principle:
The Main Factors of water erosion community water and soil conservation observation comprises: rainfall amount, run-off and quantity of sand and mud.
Its observation common method is respectively: observe rainfall amount with rain gage; Afflux pond (shunting bucket) observation calculates run-off; Quantity of sand and mud is calculated with the observation of filtering drying weight method.
(2) traditional runoff observation on plots method Problems existing:
Traditional runoff plots rainfall, runoff and monitoring sediment, its principle is simple, but observation, process and calculation procedure are complicated, and management operating cost is high.
Quantity of sand and mud observation mainly contains two kinds of methods, and one is weighting method after dried, and one is hydrometer method.Hydrometer method is suitable for the mensuration of suspended load, and weighting method after dried had both been suitable for the mensuration that suspended load is also suitable for traction load.The mixture that the silt of water and soil conservation runoff plots is made up of traction load and suspended load, therefore can only take weighting method after dried.
Weighting method after dried, it is the basic skills that hydrological industry carries out silt observation, this kind of method precision is higher, but the instrument and equipment needed is more, inspection process program is loaded down with trivial details, need that special testing laboratory filters water sample, drying and processing and metering, informal hydrometric station difficulty can complete this kind of observation smoothly.In addition, the observed result of tradition silt observation procedure can not obtain at the scene immediately, after scene records run-off, also want (at the bottom of bucket) precipitated sludge at the bottom of subregion water sampling and collecting pit, also will respectively to process such as water sample, silt filter, dry and weighs after getting back to testing laboratory, because community is many, particularly in rainfall flood season frequently, be difficult to ensure the accurate of each community each rainfall water sample process.
In the construction of observation facility, observation subdistrict dash encloses bank and afflux groove etc., and smear concrete outside generally being built a wall by cob brick, build technique simply, engineering is also very little, easily reaches quality requirements.But afflux facility (afflux pond or afflux bucket) is built with regard to more complicated, one is water collecting pool volume size issue, if met 24 hours most torrential rain footpath stream calculation by 5 years one, the volume in afflux pond at least wants 5 cubic metres, and quantities is large, and quality and precision are difficult to ensure, if adopt afflux bucket or shunting bucket, investment is large, and cost is high, and all needs to maintain every year.
In operation, one rainfall event all needs technician's field observation rainfall amount, and change from remembering paper, water intaking, water gaging, filtering drying is weighed, and cleaning water collecting basin (bucket) etc. are time-consuming.The second stage of water and soil conservation value planning in the whole nation determines that the runoff observation number of fields of each monitoring point is at least 7, and one rainfall event all gathers 7 groups of water samples, and the corresponding rainfall of survey calculation and run-off, water sample data are easy to obscure.Conventional observation method needs special messenger's observation, but observation time is only limitted to the 6-9 month, have to again dismiss observation personnel in non-rainy season, this technician temporarily employed, cannot ensure accuracy of observation, is also difficult to raise rainy season and observes running cost, therefore a lot of observation subdistrict, run and just cannot support down less than several years, have to give up halfway, effect when setting up originally cannot be played.
For convenience of carrying out the experiment work of water erosion district monitoring quickly, ensureing under the requirement that operability and raising accuracy of observation require, be necessary very much to improve monitoring method, monitoring instrument, facility that research and development are advanced, reach construction cost reasonable, running program is easy, and management operating is convenient, obtains best monitoring result with minimum input.
In water and soil conservation value observation experiment, be the link of most critical to the weighing of silt.Existing weighing mode be through sampling jar sampling, stir, be inverted in beaker, measure quality and water volume, dry in drying baker, after take earth weight, calculate sediment charge, draw erosion modulus.Single with regard to link of weighing, existing problem have following some:
Link is many, and process is loaded down with trivial details, needs carefully will produce error slightly because of carelessness in each process, if produce water clock, sampling jar confusion, then can directly produce error and even cause test failure.
Labor intensive and time, sample after each rain, each observation subdistrict must sample three bottles, label one by one, weighs, measures, dries, weighs, calculates, and each observation field is ten observation subdistricts at least, 30 at most, after one rainfall event, workload is very large, and at least will take a time on working day just can by complete for this work.Separately, baking duration is longer, extends the working time again.
