A kind of runoff field, comprise ,Jie Liu pond, experimental plot and escape canal, be provided with an end in the described bottom that connects the stream pond and connect stream pond internal communication, the other end is positioned at the bottom discharge pipe that connects stream outside, pond, be provided with successively valve at this bottom discharge pipe near an end of its outfall and for measuring the first metering water meter of displacement, be provided with on the top that connects the stream pond top gutter be communicated with it, the end at this top gutter near its outfall is provided with for measuring the second metering water meter of displacement.
In one embodiment, described top gutter is " Z " shape, wherein the port of an end is positioned at the port that connects stream pond, the other end and is positioned to connect and flows the outside, pond, the middle part of top gutter is built in the pool wall that connects the stream pond, its two ends port is positioned at same level, and described the second metering water meter is connected with the middle part of top gutter.
Wherein, described connect stream pond be brick mix structure.
In order better to realize the utility model, in this runoff field, the pond connection possesses the sand trap function simultaneously.
As a kind of optimal way, described bottom discharge pipe, top gutter are pvc pipe.
Further, described bottom discharge pipe, top gutter are positioned at the pipe shaft part that connects stream outside, pond and all are enclosed with topping.
Further, described topping is made by cement or concrete.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model design is ingenious, simple in structure, with low cost.
(2) the utility model only needs to build one and connects the stream pond, and the upper and lower that simultaneously at this, connects the stream pond is equipped with for measuring the metering water meter of displacement: the first metering water meter and the second metering water meter, when the metering water meter of bottom is used for Active Drainage, the metering displacement; When the metering water meter on top is to connect stream pool inner water position over the top gutter, measure the displacement of passive draining, not only metering precisely, water meter for metering is cheap, and be applicable to the larger weather of amount of precipitation such as heavy rain, extra torrential rain fully, without building separately again the shunting pond, greatly reduced the construction cost of runoff field.
(3) in the utility model, the top gutter is " Z " shape, and the second metering water meter is connected with its middle part, thereby has improved the accuracy that metering water meter records displacement.
(4) in the utility model, bottom discharge pipe, top gutter are positioned at the pipe shaft part that connects stream outside, pond and all are enclosed with topping, can effectively protect drainage pipe not corroded by rainwater or its thing damages.
(5) in the utility model, each component are by common product on the market, and it is with low cost, manufacture simply, not only possess novelty and creativeness, and possess very high practicality, for it, apply on a large scale, established solid foundation.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.Embodiment of the present utility model includes but not limited to the following example.
Embodiment
Connect stream pond and shunting pond comprising in existing runoff field, and the pool inner water position changes by visually observing, construction cost is high, and the detection accuracy is low.In order to overcome above-mentioned defect, the present embodiment provides a kind of runoff field, as shown in Figures 2 to 4, this runoff field comprises ,Jie Liu pond, experimental plot 1 and escape canal three parts, connecing the stream pond is brick mix structure, and on this basis, runoff field also can be set up the parts such as channel of approach, reservoir according to actual needs.
