A kind of underground captation that the utility model is provided, mainly including dewatering well, the pump housing 1, spongy layer 2, fine sand layer
3rd, rubble sublayer 4, the first steel plate, the second steel plate, base plate 5 and bottom 6, as shown in Figure of description 1.
The set-up mode of dewatering well may be referred to prior art, and the pump housing 1 is located at the inside of dewatering well, in dewatering well
The sewage in portion carries out pump drainage.Core of the present utility model is, the madial wall of dewatering well set gradually from inside to outside spongy layer 2,
First steel plate is set between fine sand layer 3 and rubble sublayer 4, and spongy layer 2 and fine sand layer 3, fine sand layer 3 and rubble sublayer 4 it
Between the second steel plate is set, the first steel plate and the second steel plate are respectively provided with through hole；It is intended that the impurity such as mud in sewage can be with
Spongy layer 2, the through hole of the first steel plate, fine sand layer 3, the through hole of the second steel plate and rubble sublayer 4 are sequentially passed through, and then plays purification
The purpose of sewage.
Dewatering well be usually arranged as it is cylindric, diameter between 300mm~400mm, spongy layer 2, fine sand layer 3 and blinding
Three layers of thickness can be set identical by layer 4 as three layers of filter layer of unlike material, and thickness can be arranged on 45mm~55mm
Between.
First steel plate and the second steel plate can support spongy layer 2, fine sand layer 3 and rubble sublayer 4, due to the first steel plate and
Two steel plates are arranged between spongy layer 2, fine sand layer 3 and rubble sublayer 4, thus the first steel plate is not perishable with the second steel plate, energy
Enough play preferable support effect.
The thickness of the first steel plate and the second steel plate can be arranged between 5mm~10mm；First steel plate and the second steel plate
Through hole can pass through for impurity such as the mud in sewage；By actual test, the madial wall of dewatering well sets gradually from inside to outside
Spongy layer 2, fine sand layer 3 and rubble sublayer 4 can to greatest extent purify sewage, and coordinate the first steel plate and the second steel plate
Supporting role so that the service life of underground captation is obviously prolonged；Certainly, the first steel plate and the second steel plate can be using not
