Water storage type ecology tree pond
It the utility model is related to a kind of water storage type ecology tree pond, more particularly to a kind of storage for being used to handle rainwater runoff pollution
Water type ecology tree pond.
Ecology tree pond belongs to one kind that biology is detained facility, is generally arranged at town road, in park irrigation, is mainly used in
Rainwater runoff pollution processing.Ecology tree sets certain dischargeable capacity to collect early-stage rainwater in pond, and the early-stage rainwater of collection is entering
Due to being purified under the collective effect of plant and soil during oozing.Rainwater after purification is discharged to municipal Storm Sewer Network, mesh
Preceding ecology tree pond is not provided with the place of special storage rainwater, the waste of rainwater resource is caused, simultaneously because contaminated rain water
Residence time it is inadequate, it is bad to the removal effect of partial contamination thing.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of water storage type ecology tree pond with water storage function.
To achieve these goals, the technical solution of the utility model is as follows：A kind of water storage type ecology tree pond, including tree pond
Body, it is characterised in that：The bottom of the tree pond body is bottom water reserve, in the top of tree pond body inner bottom part water reserve under
To being above disposed with sand filter blanket, soil horizon and coating, the top of the coating is water area, in the bottom water reserve
Equipped with bulk gravel, drainpipe is provided with the bottom water reserve, the drainpipe is by bottom transverse direction perforated drain pipe, vertical
Pipe and top drainpipe composition, bottom transverse direction perforated drain pipe, vertical duct and the top drainpipe connect into Z-shaped, described
The distance between bottom of top drainpipe and soil horizon is more than or equal to 150mm, and wherein bottom transverse direction perforated drain pipe is located at bottom
The bottom of portion water reserve.
Using such scheme, early-stage rainwater is collected in water area, in the presence of coating, reaches filtering bulk debris
Effect, rainwater are purified processing during by the root system of soil and plant, and then rainwater filters by sand filter blanket again,
Into bottom water reserve, when the water level of bottom water reserve is higher than the height of top drainpipe, unnecessary rainwater is arranged by top
Water pipe is discharged.Rainwater stops in the water reserve of bottom, reaches the effect further precipitated, improves the water quality of discharge rainwater, mitigates
Municipal processing cost.The crop of plantation is advisable with root system more flourishing arbor or shrub, and bottom can be directly utilized by root system
The water of portion water reserve.
In such scheme：Antiseepage film is provided with the side wall of the sand filter blanket and bottom water reserve.Avoid water storage seepage.
In such scheme：The both ends of the coating are inclined upwardly separated in inverted " eight " shape.
In such scheme：The distance between bottom of the top drainpipe and soil horizon is more than or equal to 150mm.
In such scheme：A corral column is provided with the top ports of the tree pond body.
Beneficial effect：Water storage type ecology of the present utility model is oozed under setting in the realization storage ecology tree pond that pond can be simple and easy
Rainwater, improve its residence time, strengthen the removal effect to pollutant, while the rainwater accumulated is available for making during plant dry season
With improving the recycling of rainwater.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The utility model is described in further detail with reference to the accompanying drawings and examples：
Embodiment 1, as shown in Figure 1：Water storage type of the present utility model ecology tree pond by set pond body 1, bottom water reserve 2,
