Zvinobudirira dewatering: wellpoints, sei kushanda uye zvakanakira kushandisa

yekudyidzana High-nhema pasi mvura kukudzivisa zvoupfumi basa, zadza inoerera nokuti zvinhu neramangwana omesa kuvaka kwacho, kuderedza akavimbika dzavo uye mukurumari, kugeza kure nheyo. Kuti aite izvi kana kuti nzvimbo yakakodzera kuvaka, rokutanga dewatering rinoitwa. Wellpoints inoshandiswa kuderedza mvura pamwero, kubvumira kuona mabasa kunyange zvikuru kunzwisisa hydrogeological ezvinhu.

Inokosha pamusoro dewatering

Selection imwe nzira yokuti pakubata yakakwirira pasi inotsamira parameters dzakadai saizi negomba kudzika yemberi chivakwa kuvaka, ano geologic uye hydrologic ezvinhu, etc. Zvisinei, chero dewatering zvemichina rinoshandiswa rimwe chinangwa: .. achideredza ari pasi kuti kudzika yakadaro pamusoro izvo havagoni kudzivisa rokuvaka.

The musimboti wenyika dewatering nzira iri kuumba mwoyo fanera. Pamusangano chenguva kupomba mvura muvhu rukoko siyana fanera imwe mhando. In nzvimbo dewatering rinoitwa, wellpoints dzinoumba mhango centre. Kusiyana inodiwa mvura sandara uye yakadereresa pfungwa yacho dzegirini fanera serin'i inonzi mwoyo fanera.

Kusimba uye nharaunda yacho mwoyo pamusoro fanera yakaitika pazviri chaizvo zvinodiwa uye mamiriro. Kurongwa aya vakaramba yose nguva inodiwa kuti kuvakwa kwacho. Zvakakosha kuti wellpoint dewatering wakange zvachose hunhu, sezvinonzi kupomba anomiswa, pasi mvura achamuka pakutanga padanho.

patani wellpoints

mano aya ine kumicheto, ari kubvisa kuguma izvo Sefa iri iiswe. Nokuda pamberi Sefa iri kugadzwa harwuwire wellpoint nezvishoma (ivhu, jecha, dombo zvimedu, uye zvakasiyana. D.).

The dhayamita uye pakureba sepombi takatsunga zvichienderana kudzika yemberi kupikidura, ivhu zvivako uye aida bandwidth.

The algorithm unoshanda wellpoints

Kukarukureta pakati wellpoints amakavaitira kuremekedza anodikamwa dhayamita yacho fanera. In akarurama nzvimbo zvokushandisa zviri kuiswa pasi panzvimbo apo mvura pamwero ichaitwa. Wellpoints vachishandisa mumwe rukoronga kwakabatana kuti pombi kuti kupomba mvura. Rukoronga chinogona kuitwa kubva rabha, simbi, kana mamwe marudzi pombi. The chikuru ndechokuti yakavimbika.

Pamwero wellpoint dewatering tichabudirira zvinoenderana zvakakodzera kusarudzwa pombi vanokwanisa uye kuverenga mari uye ruzivo dhayamita yacho kubvisa nyere. Zvisinei, dzimwe nguva haugoni kubereka zvikasabudiswa rakazara rine mvura ivhu, kwamakadarika pamusoro imwe aquitard rukoko mvura (0.5-1 m) anoramba. Kubviswa Its Kazhinji kuitwa urongwa nguva yokutanga uye dewatering kushanda Mobile kupomba enyika kuti kupomba mvura kubva kwavari.

Wellpoint dewatering unyanzvi

Pane nzira dzakasiyana-siyana kuderedza nenhanho pasi Via wellpoints.

• Kana basa rokuvaka kunodiwa zvishoma dewatering, wellpoint pombi vanozviriritira priming uye nyore. Zvombo zvakadaro kunogona kuderedza padanho pasi mvura kuti kudzika 4,5-8,5 m. Kana zvakakodzera kushanda kusvikira kunonyanyisa kudzama dewatering anoshandisa anokosha wellpoints ane Tiered marongerwo.
• Kana pasi pamwero anofanira kuderedzwa kuti kudzika 18-20 metres, uchishandisa chaiyo ejector wellpoints mvura pombi - ejector.
• Centrifugal pombi soro simba zvakadzama inoshandiswa dewatering kuti kudzika pamusoro 20 mamita.
• The Vacuum nzira kunobva pakushandisa anokosha ejectors umo Vacuum firita nzvimbo. Kwakadaro hurongwa vanokwanisa zvinobudirira kuderedza mwero chenyika mvura hydrogeological ezvinhu vawedzere kunzwisisa.

Selection imwe nzira iri inobva dewatering zvinoitwa pasi, zvinhu zviri panowanikwa yavo uye vanokwanisa pakati aquifer. Mukuwedzera, Sefa coefficient anonzi kunodiwa, nharaunda vakapedzwa nzvimbo kugadzirwa mabikirwo kuvakwa kana migodhi kushandiswa, ya dewatering uye dewatering zvechadenga michina.

kugadzwa wellpoints

Kusarudza kugadzwa dewatering michina kunoenderana hunhu ivhu iri nzvimbo ramangwana kuvakwa mabasa.

• Hydraulic nzira kugadzwa kutevedzerwa kudiwa kuderedza mwero wemvura iri kuwanikwa uye grained jecha nevhu. nzira iyi zvinosanganisira Kubayiwawo jekiseni mvura Sefa mudziyo, iyo zvino kutura muvhu.
• Zvokuimba nzira chokugadza pachii wellpoint dewatering mu mavhu uye nevhu nevhu. For matsime abudise kare akachera vachishandisa chinokosha michina.

The nzira Zvakanyanya Kunaka Panguva Yepamuviri rokururamisa wellpoints uye nokuwanda takatsunga ne kukura nzvimbo abudise uye ivhu unhu.

Zvakanakira kushandisa wellpoint

• Kuwanikwa dewatering michina.
• Mufambo uye vakasununguka naro wegadziriro.
• No vanofanira kushandisa magetsi (wellpoints vanomhanya pamusoro Diesel).
• Kunyatsoshanda basa.
• Low mari dewatering tichienzanisa nedzimwe nzira.
• High kunyatsoshanda.
