Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the technical scheme in this utility model embodiment is carried out clear, complete
Describe, it is clear that described embodiment is only a part of preferred embodiment of the present utility model rather than whole realities wholely
Execute example.Those skilled in the art can do similar deformation in the case of this utility model intension, and therefore this practicality is new
Type is not limited by following public specific embodiment.
First embodiment
As depicted in figs. 1 and 2, this sponge urban construction ground water recharging well includes that a boring 2, described boring 2 can be arranged
The place such as below roadside, lawn, parking lot, porous pavement, in community or unit institute, it is possible on the infiltration pool, seepage well, the wet pool,
Rain-fed wetlands etc. are internal to be used.
As described in Figure 2, this boring 2 is arranged on road surface 1 at lawn 8 or in lawn 8.Described road surface 1 can be that city is built
If horizontal wall inscription common in is the road surface of 1.5%-2%, it is possible to is optimized for the road surface 1 of gradient 3%-5% further, does not change original
Road structure, when there being precipitation to occur, rain (or snow melt) water will quickly flow to along slightly-inclined road surface 1 enter in boring 2.
Boring 2 cuts through after aquiclude 5 to aquifer sand layer 6 becomes well, first lays 20-30cm sand gravel bottom boring 2 anti-
Filtering layer 7, is then contained in hard foam 4 on the sand gravel loaded filter 7 of bottom.
A kind of more excellent design, the external sheath of described hard foam 4 has one layer of geotextiles.
A kind of more excellent design, the diameter of described hard foam 4 is more than boring aperture.When so installing sponge and the borehole wall it
Between there is not space.
Described hard foam 4 can be sized for one section or several sections (can make one section of 5-10 rice) by drilling depth, firmly
The distance on matter sponge 4 top to ground 1 is 20-30cm, places one layer of geotextiles bigger than orifice area the most again, the most again
Layer of sand loaded filter 3 of mating formation, to flushing with road surface 1 or lower slightly (common soil layer of can mating formation above again time lower slightly), forms subsoil water and returns
Fill well.
This inverted well, first directly uses rig punching, fills with high-density sponge, and easy to process, backfill is convenient, and
Avoid common seepage well to need to buy multiple backfilling material, the shortcoming wasted time and energy.
Although also there being similar seepage well to be made without backfilling operation, however it is necessary that employing wall casing supports, this well is at rain
Easily causing blocking during Water Spreading, if well head is open type, dangerous, night or other cas fortuits are easy
Fall into wherein, cause casualties.And the inverted well in the application, use hard foam, first hard foam to play support and make
With, borehole collapse or sinking of ground will not be caused, even if local deformation situation of holing can occur, as the buffering of sponge is made
With, do not affect rain infiltration, more personnel will not be caused injures and deaths.
Compared with common seepage well, because water is immersion liquid, and sponge has absorption, permeable and filtration, in sponge
Can carry out the infiltration of current under adsorption rapidly, strengthen and infiltrate effect, the impurity in rainwater can be filtered out simultaneously.Simultaneously
The improvement project of this boring is convenient, does his use as changed, it is not necessary to secondary punches, time saving and energy saving.

Top be provided with an inverted well joint 10, on described inverted well joint 10, spiral is provided with the permeable well lid 9 that recharges, and well lid is slightly
Being above the ground level, this design can avoid early-stage rainwater pollution problem, and later stage clean rainwater can be by there being chemosmotic permeable time
Fill well lid 9 to penetrate into.
It is provided with interface channel 12 in hard foam 4 side, as described in Figure 4, is provided with some connections at hard foam periphery
Passage 12, described interface channel 12 can be U-lag, arcuate groove or other there is the cell body of connection ability, at described interface channel
Sponge strip 11, described sponge strip 11 and the mating shapes of interface channel 12 it is placed with in 12.Vertical or horizontal connection is set
Passage 12, it is possible to intercommunication between different inverted wells, can guide other inverted wells by the rainwater having little time to infiltrate.
A kind of more excellent design, is coated with a steel wire outside interface channel, is provided with sponge inside described steel wire
Layer, this design steel wire provides certain support force, and spongy layer can carry out the infiltrating to interface channel of moisture rapidly
In, the beneficially water conservancy diversion of rainwater.
3rd embodiment
As it is shown in figure 5, be to be provided above a road side stone at hard foam 4 with the difference of first embodiment
13, in described road side stone, it is provided with the L-shaped passage for rainwater diversion.
A kind of more excellent design, is provided with layer of sand loaded filter between hard foam and road side stone.
This being designed to, on the basis of not destroying existing road, is transformed, low cost, can well carry out again rain
The infiltration of water.
4th embodiment
It is with the difference of above-mentioned first three embodiment, is provided with in the middle part of the hard foam filled in the middle part of boring 2
One vertical passage, this vertical passage is cross scarfing, circular port, or other shape holes.
This design, it is possible to when needs moisture, by going deep into water pipe with this vertical passage or other water drawing devices enter
Row water intaking uses or detection, chemical examination.
This design, also can be converted into this inverted well a detection well or monitoring well, be provided with in described vertical passage
One wire, described wire connects and has sensor, in order to detect or to monitor level of ground water, water quality, water temperature or other parameters.Described
Sensor is level sensor, water quality sensor or temperature sensor.
5th embodiment is as shown in Figure 7.
Part unlike the embodiments above is, is provided with an outer tube in the middle part of the hard foam 4 filled in the middle part of boring 2
17, described outer tube 17 is provided with some flushing holes 18, when rainwater etc. is after repeatedly recharging, can be outside hard foam 4
Side remains dust impurity or other article, by flushing hole 18, by these impurity, hard foam 4 bath can be washed from hard
Outside sponge 4, be conducive to more preferably carrying out faster recharging work.
Described outer tube 17 is also nested with for drawing water or the water pipe 16 of water sampling, or leading of sensor is installed
Line.
