Description
Technical field
The invention belongs to purifier, relates generally to a kind of bleed back well water treatment plant for rainwater self-purification.
Background technology
Sponge urban construction is the important content of China's Ecological Civilization Construction, and wherein, one of important behave is just to increase
The lower milliosmolarity of surface water.How to increase and ooze under surface water, pollute original subsoil water becomes the emphasis of current research simultaneously and not.
At present, gravel stake and underground seepage well are to increase one of capital equipment of milliosmolarity under surface water, but, milliosmolarity and tune in the presence of the former
Accumulation of energy power is little, the shortcoming of water drainage DeGrain；Though the latter increased milliosmolarity under surface water, water purifying effect is poor, exists
The contaminated potential collision hazard of subsoil water, and underground seepage well easily blocks, service life is limited.
Content of the invention
The purpose of the invention is aiming at the problem that above-mentioned prior art exists, and provides a kind of naturally net for rainwater
That changes bleeds back well water treatment plant, reaches that lightweight, flexible, good penetrability, Regulation capacity be big, the purpose of long service life.
The purpose of the invention is realized in：Grain is pasted successively from the inside to the outside on pvc pipe or outer wall of steel pipe face
The haydite patch gravel bed that footpath size is gradually reduced, and the grain size of outermost haydite patch gravel bed is close with rock grain size,
The thickness of every layer of haydite patch gravel bed is 10-30cm, pastes in haydite and contains equipped reinforcing bar cylinder on outside gravel bed, in described pvc pipe
Or it is fixedly mounted with closure steel plate on steel pipe, haydite patch gravel bed and reinforcing bar cylinder bottom, the upper lid steel plate with central through hole is fitted in
On pvc pipe or steel pipe and haydite patch gravel bed upper end, described upper lid steel plate is fixedly connected with reinforcing bar cylinder, and screw thread type sleeve pipe configures
Above upper lid steel plate and affixed with upper lid steel plate and reinforcing bar cylinder, the reinforcing rod top of described reinforcing bar cylinder is in that bending is hook-shaped,
Through hole is provided with described pvc pipe or steel pipe tube wall, and the hole of the described through hole gross area and pvc pipe or steel pipe tube wall gross area ratio
Gap rate is 13-25%, and described through hole includes horizontal stripe seam through hole or vertical bar seam through hole or circular hole or elliptical aperture, so far structure
Become a kind of and bleed back well water treatment plant for rainwater self-purification.
The invention is added significantly to the lower milliosmolarity of surface water, water quality is purified simultaneously, and possesses certain
Adjust the ability of flood prevention waterlogging.This apparatus structure is novel, reasonable, simple, using reliability, lightweight, and intensity is big, good penetrability, corrosion resistant
Erosion, low cost, long service life, can be widely used for bleeding back in well.

Specific embodiment
Below in conjunction with the accompanying drawings the invention embodiment is described in detail.A kind of returning for rainwater self-purification
Seepage well water treatment plant, pastes the haydite patch gravel that grain size is gradually reduced on pvc pipe or steel pipe 5 outside wall surface from the inside to the outside successively
Layer 4, and the grain size of outermost haydite patch gravel bed 4 is close with rock grain size, the thickness of every layer of haydite patch gravel bed 4 is
10-30cm, pastes in haydite and contains equipped reinforcing bar cylinder 3 on outside gravel bed 4, in described pvc pipe or steel pipe 5, haydite patch gravel bed 4 and
Closure steel plate 2 is fixedly mounted with reinforcing bar cylinder 3 bottom, the upper lid steel plate 6 with central through hole is fitted in pvc pipe or steel pipe 5 and pottery
On grain patch gravel bed 4 upper end, described upper lid steel plate 6 is fixedly connected with reinforcing bar cylinder 3, and screw thread type sleeve pipe 7 configures in upper lid steel plate 6
Top, and affixed with upper lid steel plate 6 and reinforcing bar cylinder 3, the reinforcing rod top of described reinforcing bar cylinder 3 is in that bending is hook-shaped, described
Pvc pipe or steel pipe 5 tube wall are provided with through hole 1, and the hole of described through hole 1 gross area and pvc pipe or steel pipe 5 tube wall gross area ratio
Rate is 13-25%, and described through hole 1 includes horizontal stripe seam through hole or vertical bar seam through hole or circular hole or elliptical aperture.
During use, rainwater enters in pvc pipe or steel pipe 5 from filter well upper end through upper lid steel plate 6 centre bore, via through holes 1 and
Haydite patch gravel bed 4 enters in underground reservoir at the muscle hole of reinforcing bar cylinder 3 after filtering and stores.The particle diameter that haydite pastes gravel bed 4 is big
Depending on I is according to bleeding back the rock particle diameter of the corresponding water-bearing layer of well (group).Because haydite pastes gravel bed 4, there is higher adhesion strength,
Meanwhile, bottom and side have reinforcing bar cylinder 3 to reinforce, and pvc pipe or steel pipe 5 have preferable toughness, thus it is guaranteed that bleeding back well again
Purifier has higher intensity and toughness.Because haydite is spherical in shape, regular shape and carry micropore, in turn ensure that by itself plus
The haydite patch gravel bed 4 of work has higher porosity and permeability.Haydite has acid and alkali resistance, salt and electrochemically resistant corrosion in itself
Performance characteristics, therefore extend the service life that haydite pastes gravel bed 4.Meanwhile, whole purifier can integrally propose, convenient clear
Wash, greatly increased the service life bleeding back well.
