Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment is only a part of preferred embodiment of the present invention, rather than whole embodiments.This
Art personnel can do similar deformation in the case of without prejudice to intension of the present invention, therefore the present invention is not by following public
The limitation of specific embodiment.
First embodiment
As depicted in figs. 1 and 2, the sponge urban construction ground water recharging well includes a drilling 2, and the drilling 2 is settable
Roadside, lawn, parking lot, below porous pavement, the place such as in cell or unit institute, also can the infiltration pool, seepage well, the wet pool,
Used inside Rain-fed wetland etc..
As described in Figure 2, the drilling 2 is arranged on road surface 1 at lawn 8 or in lawn 8.The road surface 1 can be built for city
If common horizontal slope is 1.5%-2% road surface in, also can further be optimized for gradient 3%-5% road surface 1, not change original
Road structure, when there is precipitation generation, rain (or snow melt) water will be quickly flow into drilling 2 along slightly-inclined road surface 1.
It is first anti-in the 2 bottoms laying 20-30cm sand gravels that drill after drilling 2 cuts through aquiclude 5 to aquifer sand layer 6 into well
Filtering layer 7, then by hard foam 4 on the sand gravel loaded filter 7 of bottom.
A kind of more excellent design, the external sheath of the hard foam 4 have one layer of geotextiles.
A kind of more excellent design, the diameter of the hard foam 4 are more than boring aperture.When so installing sponge and the borehole wall it
Between space is not present.
The hard foam 4 can be sized for one section or several sections (can make one section of 5-10 rice) by drilling depth, firmly
Distance of the top of matter sponge 4 to ground 1 is 20-30cm, places one layer bigger than orifice area of geotextiles, Ran Houzai again thereon
Layer of sand loaded filter 3 mat formation to being flushed with road surface 1 or lower slightly (can mat formation common soil layer above again when lower slightly), forms underground water and returns
Fill well.
This inverted well, first is directly punched using rig, is filled with high-density sponge, easy to process, and backfill is convenient, and
Avoiding common seepage well needs to buy a variety of backfilling materials, the shortcomings that wasting time and energy.
Although also there is similar seepage well to carry out backfill operation, need to support using wall casing, this well is in rain
Easily cause blocking during Water Spreading, dangerous if well head is open type, night or other cas fortuits are easy
Fall into wherein, cause casualties.And the inverted well in the application, using hard foam, hard foam first plays support and made
With, borehole collapse or sinking of ground will not be caused, even if can occur drill local deformation situation, as sponge buffering make
With not influenceing rain infiltration, more will not cause injures and deaths to personnel.
Compared with common seepage well, because water is immersion liquid, and sponge has absorption, permeable and filtration, in sponge
The infiltration of current can be rapidly carried out under suction-operated, effect is infiltrated in enhancing, while can filter out the impurity in rainwater.Simultaneously
The improvement project of the drilling is more convenient, and his use is done as that need to change, it is not necessary to secondary punching, it is time saving and energy saving.
Second embodiment
As shown in Figure 3 and Figure 4, it is to be added with wellhead connection device, the well head with the difference of first embodiment

The infiltration of water.
Fourth embodiment
It is with the difference of above-mentioned first three embodiment, is provided with the middle part of the hard foam of the middle part of drilling 2 filling
One vertical passage, this vertical passage are cross scarfing, circular port, or other shapes hole.
This design, can be when needing moisture, by going deep into water pipe or other water drawing devices with the vertical passage to enter
Row water intaking uses or detection, chemical examination.
This design, the inverted well can be also converted into a detection well or monitoring well, be provided with the vertical passage
One wire, sensor is connected with the wire, to detect or monitor level of ground water, water quality, water temperature or other specification.It is 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, the middle part of hard foam 4 of the middle part of drilling 2 filling is provided with an outer tube
17, some flushing holes 18 are provided with the outer tube 17, can be in the outer of hard foam 4 after rainwater etc. is by multiple recharge
Side remains dust impurity or other articles, these impurity can be washed from into hard to the bath of hard foam 4 by flushing hole 18
The outside of sponge 4, be advantageous to more preferable progress recharge work faster.
Also it is nested with the outer tube 17 for drawing water or the water pipe of water sampling 16, or leading for sensor is installed
Line.
