Multi-tiered littoral runoff collecting device of littoral belt
Technical field
The utility model relates to the ecological engineering of environment field, is specifically related to multi-tiered littoral runoff collecting device of littoral belt.
Background technology
The severe problem that migration is present China ecology, environment in the soil of soil erosion, pollution of area source, agricultural ground nutrient loss, pollutant and nutrient, agriculture and forestry faced, and runoff is the occasioner and the main carrier of these processes.Therefore people attach great importance to research and the monitoring to runoff, and must the water level and the flow of runoff be gathered in research and the monitoring, cause and use very extensively at the water level of runoff and the harvester of flow, but at bigger rivers and lakes, have specially at bank band runoff particularly the harvester of bank band multilayer level runoff aspect also do not have, the harvester of opposite bank band that uses and multilayer level runoff aspect thereof still is runoff field and standard pool mainly at present, and the defective of these devices is as follows:
In gatherer process, runoff field and standard pool are subjected to the influence of external environment easily, and gained is gathered the fiduciary level deficiency of runoff water; To the difference of different gradient monitoring ground, runoff field and the standard pool collection length that expends time in can not be carried out simple collection; And the bank band multilayer level runoff of different terrain has in various degree requirement to the collection area of runoff field and standard pool, if cause area little thus, the representativeness of gathering runoff water is not strong, and if area is big, gather the runoff water difficulty.
The utility model content
In order to overcome the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide multi-tiered littoral runoff collecting device of littoral belt, by bank band runoff collecting device being set in different vegetational zone layerings, utilize its water inlet pipe the runoff water of being gathered to be delivered in the water container that is built in safety box, such apparatus structure is simple, can realize interior runoff collection of short time to different vegetational zones and combination thereof, simple; This device is easy for installation in addition and replacement is convenient, can satisfy the requirement of the bank band multilayer level runoff collection of different terrain.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Multi-tiered littoral runoff collecting device of littoral belt, comprise more than one bank band runoff collecting device, this bank band runoff collecting device has an end was sealed and had blasthole 2 by lid 3 water inlet pipe 1, the other end of water inlet pipe 1 passes the side of the safety box 4 of band top cover 10, and this end is positioned at mouthful top that is filled with water of the water container 5 of safety box 4 inside, and water inlet pipe 1 is inclined upwardly with respect to horizontal level by an end of lid 3 sealings.
Described safety box 4 bottoms have more than one infiltration hole 6, and this safety box bottom is provided with booster material 9, and this booster material 9 has supporting with it drainpipe 8.
By bank band runoff collecting device being set in 11 layerings of different vegetational zones, utilize its water inlet pipe 1 runoff water of being gathered to be delivered in the water container 5 that is built in safety box 4, such apparatus structure is simple, can realize interior runoff collection to different vegetational zones and combination thereof of short time, and is simple; This device is easy for installation in addition and replacement is convenient, can satisfy the requirement of the bank band multilayer level runoff of different terrain.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, bank band multilayer level runoff collecting device, comprise more than one bank band runoff collecting device, this bank band runoff collecting device has an end was sealed and had blasthole 2 by lid 3 water inlet pipe 1, the other end of water inlet pipe 1 passes the side of the safety box 4 of band top cover 10, and this end is positioned at mouthful top that is filled with water of the water container 5 of safety box 4 inside, with respect to the horizontal level slight inclination that makes progress, described safety box 4 bottoms have more than one infiltration hole 6 to water inlet pipe 1 by an end of lid 3 sealing.
As shown in Figure 2, described safety box 4 bottoms are provided with booster material 9, and this booster material 9 has supporting with it drainpipe 8, after a bank band runoff collecting device sets into the vegetational zone 11 of respective layer, there is space 12 between booster material 9 and the safety box 4, this space 12 and drainpipe 8 one end conductings, drainpipe 8 is positioned at below the face of land, places along domatic slight inclination.
Principle of work of the present utility model is: earlier different vegetational zone layering T1 is implanted in the layering of bank band runoff collecting device, T2, in T3 and the T4 as shown in Figure 3, when producing runoff during rainfall, runoff is along the blasthole 2 on domatic inflow water inlet pipe 1 surface, flow into the built-in water container 5 of safety box 4 along the tube wall of slight inclination like this, if can infiltrate soil through drainpipe 8 by the infiltration hole 6 of safety box bottom after the water spill-over goes out in the water container, so just realized different vegetational zone layering T1, T2, the runoff collection of T3 and T4, safety box 4 with top cover 10 is rainproof covering facilities simultaneously, both can prevent that foreign material such as rainwater from falling into, and also prevented the people, animals etc. are destroyed water container and the water sample in the case.Such apparatus structure is simple, can realize interior runoff collection to different vegetational zones and combination thereof of short time, and is simple; This apparatus structure is simple and easy for installation in addition, and it is convenient to replace, and can satisfy the requirement of the bank band multilayer level runoff of different terrain.
