Opanga zida zobowola m'madzi a pneumatic amakuuzani momwe mungathanirane ndi magawo osiyanasiyana a dothi omwe amakumana ndi zida zobowola madzi.

Monga wopanga zitsime zobowola madzi a pneumatic, timamvetsetsa kuti zopangira zitsime zamadzi a pneumatic ziyenera kutengera njira zosiyanasiyana zikakumana ndi magawo osiyanasiyana pobowola kuti tipeze zotsatira zabwino. Mitundu yosiyanasiyana ya geological iyeneranso kukumana, monga gypsum layer ndi quicksand layer. Kamodzi gypsum kulowerera kumachitika pa kubowola ndondomeko pneumatic madzi chitsime pobowola Rig, kashiamu ayoni akhoza kuchotsedwa ndi kupezeka koloko phulusa, kuchotsa kashiamu ndi kuchepetsa mamasukidwe akayendedwe. Pakalipano, wothandizira kuchepetsa mamasukidwe amphamvu ndi calcium kukana amphamvu angagwiritsidwe ntchito kulamulira mamasukidwe-kuchepetsa kuchepetsa ndi kupanga kusowa kwa fyuluta-kutaya-kuchepetsa wothandizira, anti-kugwa wothandizira ndi zipangizo zina.

I. Gypsum layer

Musanabowole gypsum wosanjikiza, madzi akubowola a gypsum amapangidwira kuti achepetse gawo lolimba komanso kukhuthala, komanso othandizira odana ndi gypsum amakhudzidwa (mwachitsanzo, phulusa la soda, chochotsera kashiamu, chochepetsera kukhuthala, etc.). Ndipo malinga ndi zipangizo zomangira zitsime zoyandikana nazo, wothandizira mankhwala ochizira gypsum wosanjikiza amakonzedwa pasadakhale. Limbikitsani kuchuluka kwa pH yamadzi obowola m'chitsime chamadzi, ndikuwongolera luso la makina ang'onoang'ono obowola chitsime chamadzi kuti mupewe kuipitsidwa kwa gypsum.

Chachiwiri, wosanjikiza mchenga

Pamene pobowola mu quicksand mapangidwe, m`pofunika kuwongolera mamasukidwe akayendedwe a pobowola madzimadzi ndi bentonite zili m'madzi chitsime pobowola pobowola madzimadzi, amene nthawi zambiri chofunika kukhala pamwamba 10%. Pofuna kupititsa patsogolo ntchito yopangira khoma la madzi opangira chitsime chamadzi, kukokoloka kwa mchenga wa quicksand kumachepetsedwa pambuyo pochepetsa moyenera kusamuka kwa polojekitiyi. Asanayambe kubowola, gawolo liyenera kutsekedwa ndi matope okhuthala ndi kukhuthala kwakukulu kuposa 80 kuti zitsimikizire kuyambika kosalala ndi kuyimitsidwa kwa kubowola, kudula mitengo yamagetsi ndi kusungitsa makina ang'onoang'ono amadzi obowola.

III. Quartz sandstone

Ngati nthawi ya sandstone imakhala yolimba kwambiri, pobowola nthawi zambiri imawonekera pang'onopang'ono pobowola. Pakhoza kukhala mamita awiri a mchenga pobowola mita imodzi, zida zobowolera zimalumpha mwamphamvu, kudula kwa slag ndi kukwiriridwa zolakwika zoboola. Choncho m'pofunika kumvetsa bwino malowa.

Madzi abwino alibe mafuta monga matope, ndipo zida zobowolera m’miyala yolimba zimalumpha kwambiri mwakuti thanthwelo limasweka pamene zida zobowolera zidumpha; madzi oyera ali ndi malo akulu osankhika, ndipo madzi otsekemera sangathe kunyamula miyala ikuluikulu yomwe ikuchulukirachulukira kuchoka mudzenje. Nsomba za miyala ngati mchenga zinkangoyandama n’kumira m’dzenjemo. Ngati chubu chochotsa ufa chigwiritsidwa ntchito, mita imodzi kapena ziwiri za mchenga zitha kubowoledwa. Kusasamala pang'ono kungakwirire chobowolacho, ndipo mchenga wochulukirapo ungayambitse vuto lalikulu pakuchotsa dzenjelo.

Mwala wa mchenga pa nthawi yogwiritsira ntchito umapangidwa ndi kuikapo ndipo ndi thanthwe lolimba kwambiri. Small pneumatic madzi chitsime pobowola cholumikizira pamene kubowola dzenje ndi osaya (303354200 m), kotero ntchito wamba diamondi kubowola pang'ono bwino pobowola madzi pobowola, basi slurry, nthawi zambiri kuwonetseredwa pang'onopang'ono pobowola Makanema, mita imodzi ya pobowola kanema akhoza kuwulula mamita awiri. mchenga, pobowola chida kulumpha kwambiri, slag, chipped thanthwe kwambiri, kubowola kulephera kukwiriridwa ndi zina zotero.

Yankho: Ngati pobowola ndi matope si ndalama, mukhoza kuchepetsa kupezeka kwa mchenga ndi kudula kuchuluka kwa madzi ang'onoang'ono pobowola rigs kulumpha, inu mukhoza kuwonjezera asidi nitro ndi zina zamchere m'madzi kuchita mbali ya kugwedera damping kondomu, kotero kuti mutha kuchepetsa kuchuluka kwa zida zodumphira ndi mchenga, ndiyeno kumamatira kuyeretsa mabowo obowola amadzi a pneumatic chitsime chobowola, ndikuthetsa vutoli!
