Description
Technical field
The present invention relates to a kind of silt and collect measurement mechanism, is the instrument that the silt alluvial of a kind of falling zone is collected and measured specifically, and this instrument is applicable to the collection and the measurement of shoal materials in the seasonal falling zone of reservoir.
Background technology
The falling zone is the seasonal fluctuation in stage district that reservoir operation back forms.Vegetation is all destroyed, naked slope occurs when decline of water table, very easily suffer the naughty erosion effect of reservoir wave, add that rainfall directly hits washing away of the face of land and runoff, the soil erosion risk of soil property storehouse bank strengthens in the district.In addition, fluctuation in stage makes falling zone soil body water cut increase, and causes mass erosions such as avalanche and landslide easily.Soil erosion in the falling zone not only causes vicious cycle to ecologic environment succession in distinguishing, net result is that soil erosion is totally in the falling zone, the foundation of things forfeiture existence, a large amount of loss water and soil enter the life-span that reservoir has also been shortened in the reservoir area, simultaneously the potential influence that reservoir water quality is constituted.
The collection of falling zone shoal materials and mensuration are the important means of the understanding falling zone soil erosion and silt alluvial rule, landform evolution process and ecologic environment conversion characteristic.Because hydrologic condition complexity in the falling zone, the factor of influence erosion and deposition is a lot, study falling zone soil erosion and landform at present and develop the main topographical surveying method that adopts, the disparity estimation soil erosion amount or the silt siltation volume of alternate landform when contrasting two by measuring.Yet artificial landform measures that labour intensity is big, and precision is low, though and live forms measuring technique precision such as topography scanners, GPS are higher, cost costliness, and be subjected to the restriction of falling zone condition is unsuitable for carrying out open-air location observation.
Summary of the invention
The purpose of this invention is to provide the silt alluvial of a kind of falling zone and collect analyzer.
The object of the present invention is achieved like this: analyzer is collected in silt alluvial in a kind of falling zone, comprises gathering barrel, and gathering barrel is the cylinder of upper and lower opening, and the gathering barrel lower end is stretched in the chassis, the two formation activity matching relationship, and the gathering barrel top is provided with the trellis filter screen; Also have as the bracing frame of placing gathering barrel and chassis thereof: by being three uniform vertical mobile jibs of equilateral triangle and constituting with a plurality of lateral stability rings that three vertical mobile jibs are connected and fixed, and three vertical vertical rod lower ends are as inserting the fixing sharp cone distal in upper strata.
Above-mentioned trellis filter screen is through the fixing described gathering barrel top of last clips.
Also be fixed with following clips on the above-mentioned chassis as restriction gathering barrel and chassis upward displacement.
This falling zone silt alluvial collection measuring instrument is based on open-air silt alluvial prototype process and designs, and it mainly constitutes the silt collection system by trellis filter screen, gathering barrel, clips, chassis and lateral stability ring, vertical mobile jib are formed.
The silt collection system:
A, trellis filter screen: major function is to prevent that volume from entering in the gathering barrel than bigger material;
B, gathering barrel: being the main member of collecting and store silt, is the post parts of two sections openings;
C, chassis: the sealing part at the bottom of the gathering barrel;
D, clips: be the link between above each member
Stationary installation:
A, lateral stability ring: major function is that gathering barrel is fixed up;
E, vertical mobile jib: major function is that the gathering barrel that the lateral stability ring is fixing is connected with ground, prevents that gathering barrel from losing.
The use-pattern of this device is to be placed in the falling zone privileged site after before the falling zone water level goes up the instrument each several part being assembled, treat that water level did not have the collection bung after, the silt in the above highly water body of bung just deposits in gathering barrel.A waterflooding end cycle, decline of water table is treated that device surfaces can reclaim device.The position silt alluvial speed that instrument can be represented can be tried to achieve according to the cross-sectional area of silt collecting amount and gathering barrel, and silt can also be taken back the laboratory and do physico-chemical analysis.
The invention has the beneficial effects as follows: the present invention proposes, and the following silt alluvial collection technique of settling in an area can real-time collecting falling zone shoal materials, near falling zone silt alluvial truth, and the cost of manufacture of this device is lower, simple to operate, suitable long-term open-air location observation.

Embodiment
In conjunction with the accompanying drawings analyzer being collected in the reservoir drawdown district silt alluvial that the present invention relates to is described further.
Shown in accompanying drawing 1-1, Fig. 1-2, Fig. 1-3, Fig. 1-4, trellis filter screen 1, gathering barrel 2 all adopt the pvc pipe material, and last clips 3, down clips 3a shape is identical.The assembling mode of whole silt system is the bung that the trellis filter screen is placed in gathering barrel, is fixed with clips; Equally the chassis is placed in sampling bucket end mouth, with clips that it is fixing with the sampling bucket.
Among Fig. 2, the present invention includes gathering barrel 2, gathering barrel 2 is the cylinder of upper and lower opening, and gathering barrel 2 lower ends are stretched in the chassis 4, the two formation activity matching relationship, and the gathering barrel top is provided with trellis filter screen 1; Also have as the bracing frame of placing gathering barrel and chassis thereof: by being three uniform vertical mobile jibs 6 of equilateral triangle and constituting with a plurality of lateral stability rings 5 that three vertical mobile jibs are connected and fixed, and three vertical vertical rod 6 lower ends are as inserting the fixing sharp cone distal in upper strata.In the bracing frame: the purposes of lateral stability ring 5 mainly is fixing and upwards holds up gathering barrel; The effect of vertical mobile jib is to connect the fixing gathering barrel of lateral stability ring, and the whole device in back just is fixed on the falling zone privileged site in the bottom insertion soil layer of vertical mobile jib band point.
Trellis filter screen 1 is through last clips 3 fixing described gathering barrel 2 tops.Also be fixed with following clips 3a on the chassis 4 as restriction gathering barrel and chassis upward displacement.
In this example, the trellis filter screen adopts the braiding of tinsel material to form, and gathering barrel adopts pvc pipe, and plastic material can play anticorrosive effect, and clips and sampling bucket chassis all are plastic material.Supporting pvc pipe, chassis and clips are arranged on the market, and the making and the assembling of sampling bucket are just easier.The lateral stability ring is selected the round steel of φ 14mm for use, and vertical mobile jib is selected the round steel of φ 18mm for use, and one is made into pointed, inserts in the soil layer with convenient.
The each several part size is respectively in this example: trellis filter screen sizing grid is 20mm * 20mm; Gathering barrel external diameter 200mm, height 500mm; Lateral stability ring diameter 220mm; Vertical mobile jib length 600mm inserts wherein that the degree of depth is 300mm in the soil layer.
