1. Chidule cha polojekitiyi
Pulojekitiyi imagwiritsa ntchito njira yomangira yotseguka. Ngati kuya kwa dzenje la maziko kuli kopitirira mamita atatu ndi kochepera mamita asanu, kapangidwe kothandizira kamathandizidwa ndi khoma losungira mphamvu yokoka la φ0.7m*0.5m. Ngati kuya kwa dzenje la maziko kuli kopitirira mamita asanu ndi kochepera mamita khumi ndi limodzi, φ1.0m*1.2m bored pile + mzere umodzi φ0.7m*0.5m simenti soil mixing pile imagwiritsidwa ntchito. Kuzama kwa dzenje la maziko kuli kopitirira mamita khumi ndi limodzi, pogwiritsa ntchito φ1.2m*1.4m bored pile + mzere umodzi φ0.7m*0.5m simenti soil mixing pile.
2. Kufunika kwa kuwongolera kulunjika
Kuwongolera kulunjika kwa milu ndikofunikira kwambiri pakupanga dzenje la maziko. Ngati kulunjika kwa milu yoboola kuzungulira dzenje la maziko kuli kwakukulu, kumabweretsa kupsinjika kosagwirizana kwa kapangidwe kosungira kozungulira dzenje la maziko, ndikubweretsa zoopsa zazikulu zobisika ku chitetezo cha dzenje la maziko. Nthawi yomweyo, ngati kulunjika kwa mulu woboola kuli kwakukulu, kudzakhala ndi mphamvu yayikulu pakupanga ndi kugwiritsa ntchito kapangidwe kake mtsogolo. Chifukwa cha kulunjika kwakukulu kwa mulu woboola kuzungulira kapangidwe kake, mphamvu yozungulira kapangidwe kake sidzakhala yofanana, zomwe zingayambitse ming'alu mu kapangidwe kake, ndikubweretsa zoopsa zobisika pakugwiritsa ntchito kapangidwe kake pambuyo pake.
3. Chifukwa cha kupotoka kwa perpendicularity
Kupotoka koyima kwa mulu woyesera ndi kwakukulu. Kudzera mu kusanthula kwa polojekiti yeniyeni, zifukwa zotsatirazi zafotokozedwa mwachidule kuyambira kusankha makina mpaka kupangika kwa dzenje lomaliza:
3.1. Kusankha zidutswa zobowola, kuuma kwa geological kwa makina ozungulira obowola mulu panthawi yobowola sikofanana, kusankha zidutswa zobowola sikungakwaniritse zosowa za mikhalidwe yosiyanasiyana ya geological, zomwe zimapangitsa kuti pang'onopang'ono pang'ono, kenako kupindika kwa muluwo sikukwaniritsa zofunikira za specification.
3.2. Silinda yoteteza yabisika pamalo ake.
3.3. Kusuntha kwa chitoliro cha kubowola kumachitika panthawi yobowola.
3.4. Malo omwe khola lachitsulo lilili sali bwino, chifukwa cha kusakhazikika bwino kwa pad kuti ilamulire khola lachitsulo, kupotoka komwe kumachitika chifukwa cha kulephera kuyang'ana pakati khola lachitsulo litayikidwa, kupotoka komwe kumachitika chifukwa cha kutuluka kwa konkriti mwachangu kwambiri kapena kupotoka komwe kumachitika chifukwa cha chitoliro chomwe chimapachika khola lachitsulo.
4. Njira zowongolera kupotoka kwa mzere
4.1. Kusankha chobowolera
Sankhani zidutswa zobowolera malinga ndi momwe zimakhalira:
1. Dongo: Sankhani pansi pa chidebe chozungulira chobowolera, ngati m'mimba mwake ndi waung'ono, mungagwiritse ntchito zidebe ziwiri kapena chidebe chobowolera chotsitsa mbale.
②Dothi lopanda matope, lopanda dothi lolimba, dothi lamchenga, lopanda miyala yolimba komanso tinthu tating'onoting'ono: sankhani chidebe chobowolera chokhala ndi pansi pawiri.
③Dongo lolimba: sankhani cholowera chimodzi (pansi chimodzi ndi ziwiri) chidebe chozungulira chokumba, kapena mano a chidebe cholunjika.
Miyala yopangidwa ndi simenti ndi miyala yolimba: iyenera kukhala ndi chobowolera chozungulira chozungulira ndi chidebe chobowolera chozungulira chokhala ndi pansi kawiri (chokhala ndi mainchesi imodzi ya kukula kwa tinthu tating'onoting'ono, chokhala ndi mainchesi awiri)
⑤thanthwe lozungulira: lokhala ndi chobowolera chapakati chozungulira - chobowolera chozungulira chozungulira - chidebe chobowolera chozungulira chokhala ndi pansi pawiri, kapena chobowolera chozungulira cholunjika - chidebe chobowolera chozungulira chokhala ndi pansi pawiri.
⑥Mwala wozungulira: wokhala ndi chobowolera cha cone cone core bit - chobowolera cha conical spiral bit - chidebe chobowolera chozungulira chokhala ndi pansi kawiri ngati m'mimba mwake ndi waukulu kwambiri kuti ukwere siteji yobowolera.
4.2. Chikwama chobisika
Pofuna kusunga kuimirira kwa silinda yoteteza poika silinda yoteteza, njira yowongolera malo iyenera kuchitika patali yosiyana kuchokera pa mulu wotsogolera kupita pakati pa mulu mpaka pamwamba pa silinda yoteteza itafika pamalo omwe atchulidwa. Pambuyo poti chivundikirocho chakwiriridwa, malo apakati a muluwo amabwezeretsedwa ndi mtunda uwu ndi njira yomwe idakhazikitsidwa kale, ndipo zimawonedwa ngati pakati pa chivundikirocho pakugwirizana ndi pakati pa muluwo, ndipo zimayendetsedwa mkati mwa ±5cm. Nthawi yomweyo, kuzungulira chivundikirocho kumachepetsedwa kuti zitsimikizire kuti chili chokhazikika ndipo sichidzachotsedwa kapena kugwa panthawi yobowola.
4.3. Njira yobowolera
Mulu wobowoledwa uyenera kubowoledwa pang'onopang'ono mutatsegula dzenje, kuti apange chitetezo chabwino komanso chokhazikika pakhoma ndikuwonetsetsa kuti dzenjelo lili pamalo oyenera. Panthawi yobowola, malo a chitoliro chobowoledwa amawunikidwa nthawi zonse ndi malo olumikizirana mtunda, ndipo kupotoka kumasinthidwa nthawi yomweyo mpaka malo a dzenjelo atakhazikitsidwa.
4.4. Malo a khola lachitsulo
Kuzindikira kupotoka kwa mulu kumatsimikiziridwa ndi kusiyana pakati pa pakati pa khola lachitsulo ndi pakati pa mulu wopangidwa, kotero malo a khola lachitsulo ndi chinthu chofunikira kwambiri pakuwongolera kupotoka kwa malo a mulu.
(1) Mipiringidzo iwiri yopachika imagwiritsidwa ntchito pamene khola lachitsulo layikidwa pansi kuti zitsimikizire kuti khola lachitsulo limakhala lolunjika bwino mutanyamula.
(2) Malinga ndi zofunikira za malamulo, chotetezera chiyenera kuwonjezeredwa, makamaka pamwamba pa mulu, chotetezera chiyenera kuwonjezeredwa.
(3) Pambuyo poti khola lachitsulo laikidwa m'dzenje, kokani mzere wopingasa kuti mudziwe malo apakati, kenako tengani mtunda pakati pa pakati pa malo olumikizirana ndi kubwezeretsanso kwa muluwo pojambula muluwo ndi njira yokhazikika. Yerekezerani mzere wolunjika womwe wapachikidwa ndi pakati pa khola lachitsulo, ndikusintha khola lachitsulo posuntha pang'ono crane kuti muwonetsetse kuti malo awiriwa akugwirizana, kenako sungunulani mzere woyimilira kuti mulu woyimilira ufike pakhoma la silinda yoteteza.
(4) Konkire yothiridwa ikayandikira khola lachitsulo, chepetsani liwiro la kuthira konkire ndipo sungani malo a catheter pakati pa dzenjelo.
