Chigadziko chekuboorera mvura chine simba repneumaticVagadziri vanonzwisisa kuti michina yekuboorera mvura ine mweya inoda nzira dzakasiyana kuti iwane mhedzisiro yakanaka kana ikasangana nekugadzirwa kwakasiyana kwe geological panguva yekuchera. Izvi zvinosanganisira kusangana nekugadzirwa kwakasiyana kwe geological, senge quicksand ne gypsum layers. Kana gypsum ikapindira panguva yekuchera ne pneumatic water well rig, calcium ions inogona kubviswa nekuwedzera soda ash, kubvisa calcification, uye kuderedza viscosity. Uyezve, michina inoderedza viscosity ine calcium tolerance yakasimba inogona kushandiswa kudzora kuderedza viscosity uye kutsiva zvikanganiso zve fluid loss reducers uye anti-slump agents.
1. Gypsum Layer
Usati wachera dhaimani gypsum layer, mvura inochera iri papuratifomu yekuchera inofanira kunge yatocherwa kuti ideredze kuoma uye kusviba. Zvinoshandiswa pakurapa gypsum (zvakadai sesoda ash, decalcifying, uye viscosity reducers) zvinofanirwa kuwedzerwa. Zvinoshandiswa pakurapa gypsum layers zvinofanirwa kugadzirwa pachine nguva zvichibva pazvinhu zvekuvaka zvematsime ari pedyo. Kuwedzera pH yemvura inochera kunogona kuvandudza kuramba kwemidziyo midiki yemvura kusvibiswa negypsum.
2. Zvikamu zvejecha rinokasira
Pakuchera mujecha rinoyerera, zvakakosha kuwedzera viscosity yemvura inochera uye bentonite yemvura inochera mvura, kazhinji inoda kanenge 10%. Kuti mvura inochera mvura inochera madziro ishande zvakanaka, mwero wekutama wakaderedzwa zvakakodzera panguva yeprojekiti, zvichideredza kukurwa kwevhu mujecha rinoyerera. Usati waburitsa gomba, chikamu ichi chinofanira kuvharwa nedhaka gobvu rine viscosity inopfuura 80 kuti ive nechokwadi chekuti mvura inoyerera zvakanaka, magetsi anogogodza, uye kuiswa kwekesi nekadhi diki rekuchera mvura.
3. Dombo reQuartz Jecha
Dombo rejecha reQuartz idombo rakaoma kwazvo, rinowanzoita kuti kucherwa kunonoke. Kuchera mita imwe chete kunogona kuratidza mamita maviri ejecha, zvichikonzera kudedera kwakanyanya kwetambo dzekuchera, kuchekwa kwetsvina kakawanda, uye kutadza kuviga zvidimbu zvekuchera. Saka, kunzwisisa kwakadzama kwenzvimbo kwakakosha.
Mvura yakachena haina mafuta akaenzana nevhu, zvichiita kuti tambo yekuboorera idengenyeke zvine simba mudombo rakaoma, zvichipwanya dombo. Mvura yakachena inosarudzwa zvakanyanya, zvichiita kuti zviomere mvura iri kuyerera kubvisa zvidimbu zvakakura zviri kuwedzera kubva mugomba. Marara akaita sejecha anogara achiyangarara uye achinyura mugomba. Kushandisa pombi yekuburitsa hupfu kunogona kukonzera kuti jecha riboorwe mita imwe kana maviri. Kukanganisa kudiki kunogona kuviga chibooreso, uye jecha rakawandisa rinogona kuoma kuchenesa makomba.
Dombo rejecha rinoumbwa nekudonha kwemvura uye idombo rakaoma kwazvo. Zvibhora zvidiki zvemvura zvinoshandisa mweya zvinowanzo kuchera makomba asina kudzika (30, 33, 54, 200 metres). Nokudaro, zvibhora zvedhaimani zvinowanzo shandiswa nemvura yakachena uye kugadzira matope otomatiki. Izvi zvinowanzo konzera kumhanya kunononoka kwekuchera, nemita imwe yekumhanya kwekuchera inogona kuratidza mamita maviri ejecha. Izvi zvinogonawo kutungamira mukudonha kwakanyanya kwekuchera, kusanganiswa kwetsvina kakawanda, kuputsika kwematombo, uye kutadza kwekuchera.
Mhinduro: Kana kucherwa kwevhu kusina mari yakawanda, kugadzirwa kwejecha kunogona kuderedzwa nekuderedza kuyerera kwemvura inocherwa mugomba diki remvura. Zvinowedzerwa zve nitro-based acid-base zvinogona kuwedzerwa mumvura yakachena kuti zvideredze kutenderera uye mafuta, kuderedza kuyerera kwemvura inocherwa uye kugadzirwa kwejecha. Ramba uchichenesa gomba rekucherwa kwemvura inocherwa nemhepo kuti ugadzirise dambudziko racho!
Kana muchida rubatsiro nemudziyo wekuchera matsime emvura, tinogona kukupai mhinduro yakakwana!
