Abstract
The utility model belongs to an device for small watershed comprehensive treatment and testing, particularly relating to a slope ground soil erosion runoff district observing nine-hole shunt device which is composed of a protecting zone (1), first and second districts (7,8) and a district clapboard (9). A soil retaining wall (2) is arranged below the slope of the first and the second districts (7, 8); a water inlet (2-1) is arranged besides the district surface below the soil retaining wall (2); a water collecting groove (3) is arranged at the center of the soil blocking wall (2); a water outlet (2-2) is arranged at the other side of the soil retaining wall (2); a round flow-collecting box (4) is fixed below the water outlet (2-2); nine round holes (4-1) with the same diameter are evenly distributed at the upper end of the flow-collecting box (4); a diversion tube (5) is inserted into one of the round holes (4-1); a shunt box (6) is fixed below the diversion tube (5). The soil erosion runoff district observing nine-hole shunt device greatly reduces the occupied area and is simple in construction and saves labor and fees.
Description
Technical field
The utility model belongs to comprehensive treatment of small watersheds test device.Be particularly related to a kind of domatic surface soil erosion runoff observation on plots nine hole part flow arrangements that are used for.
Background technology
At present, comprehensive treatment of small watersheds monitoring sub-district runoff and sediment mostly is total discharge observation behind the rain, when if the runoff very few number is little, can adopt the afflux pond to collect,, promptly adopt the afflux bucket to reduce step by step and add a plurality of current divider boxs collections if the runoff and sediment total amount greatly then adopts the multi-stage diffluence method to collect, this method construction is complicated, take a lot of work, require great effort, take material, floor area is big, and the data of being gathered are not accurate enough.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides that a kind of construction is simple, floor area is little, test data soil erosion runoff observation on plots nine hole part flow arrangements accurately.
The technical scheme that the utility model technical solution problem adopts is: soil erosion runoff observation on plots nine hole part flow arrangements are by boundary belt; 1; No. 2 sub-districts; the sub-district dividing plate is formed; be characterized in 1; retaining wall is established below the hillside fields in No. 2 sub-districts; be provided with the flowing water inlet by the sub-district face below the retaining wall; in the middle of retaining wall, establish water leg; establish a flowing water outlet at the retaining wall another side; below the flowing water outlet, fix a circular manifold; 9 circular holes that diameter is identical evenly distribute in the manifold upper end; one of them circular hole is inserted with mozzle, fixes a current divider box below the mozzle.
The beneficial effects of the utility model are: soil erosion runoff observation on plots nine hole part flow arrangements can be divided into 9 parts with the big runoff that produces and flow down, only flow in the diversion box of next stage with a copy of it, can accurately test out desired data, avoided the multistage current divider box that installs additional, significantly reduced floor area, construction is simple, saves labour and funds.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows soil erosion runoff observation on plots nine hole part flow arrangement front views.
The vertical view of Fig. 2 diagrammatic sketch 1.
Among the figure, the 1-boundary belt; The 2-retaining wall; 2-1-flowing water inlet; The outlet of 2-2-flowing water; The 3-water leg; The 4-manifold; The 4-1-circular hole; The 5-mozzle; The 6-current divider box; The 7-1 sub-district; The 8-2 sub-district; 9-sub-district dividing plate;
Embodiment
Embodiment, with reference to accompanying drawing 1,2, soil erosion runoff observation on plots nine hole part flow arrangements are to mark 7, No. 2 sub-districts 8, No. 1 sub-district in the slope; No. 1 sub-district 7 and No. 2 sub-districts 8 are long 20m, and wide is 5m, establish dividing plate 9 in the middle of two sub-districts; outer periphery boundary belt 1, boundary belt 1 wide 20cm.Below the slope of No. 1 sub-district 7 and No. 2 sub-districts 8, be provided with retaining wall 2, below retaining wall 2, depend on the domatic flowing water inlet 2-1 that is provided with in sub-district, establish water leg 3 in the centre of retaining wall 2, below retaining wall 2 another face walls, establish two flowing water outlet 2-2, below two water delivering orifice 2-2, fix two circle shunts 4 made of iron, evenly divide in the upper end of shunt 4 walls and lay 9 circular hole 4-1 that diameter is identical.Be inserted with mozzle 5 among a circular hole 4-1 therein, fix a diversion box 6 below the other end of mozzle 5.
Method with the nine hole part flow arrangement tests of soil erosion runoff observation on plots is: the runoff after raining is domatic by 1, No. 2 sub-district 7,8, flowing water inlet 2-1 below retaining wall 2, flow in the water leg 3, water flows into the manifold 4 from two flowing water outlet 2-2 again, when the water in the manifold 4 reach a certain height, the big runoff that just will produce is divided into nine parts, a copy of it flows in the current divider box 6 by the mozzle of inserting among the circular hole 4-1 5, the data of gained are taken advantage of nine times of results that just can obtain district observation, test data is accurately convenient again.
Claims (1)
1; a kind of soil erosion runoff observation on plots nine hole part flow arrangements are by boundary belt (1); 1; No. 2 sub-districts (7); (8); sub-district dividing plate (9) is formed; it is characterized in that 1; No. 2 sub-districts (7); (8) establish retaining wall (2) below the hillside fields; be provided with flowing water inlet (2-1) by the sub-district face below the retaining wall (2); in the middle of retaining wall, establish water leg (3); establish a flowing water outlet (2-2) at retaining wall (2) another side; below flowing water outlet (2-2), fix a circular manifold (4); 9 circular holes (4-1) that diameter is identical evenly distribute in manifold (4) upper end; one of them circular hole (4-1) is inserted with mozzle (5), fixes a current divider box (6) below the mozzle (5).
