Nekukurumidza kukura kwehupfumi hwevanhu, migwagwa mikuru, seyakakosha hupfumi hwemagariro evanhu, yakabatsira zvikuru mukusimudzira hupfumi. Hutano uye nekurongeka kuvandudzwa kwemigwagwa mikuru hwaro hwakakosha mukusimudzira hupfumi hwenyika yangu. Yakanakisa nzira yekushanda mamiriro ndiwo hwaro hwekuchengetedzeka kwayo, kumhanyisa-kumhanya, kugadzikana uye kwehupfumi kushanda. Panguva iyoyo, kuunganidzwa kwemotokari uye mamiriro ekunze ekunze akaunzwa nebudiriro yemagariro nehupfumi zvakakonzera kukanganisa kusingaenzaniswi kumigwagwa mikuru yenyika yangu. Mhando dzese dzemigwagwa mikuru haigone kushandiswa zvakajairwa mukati menguva inotarisirwa yekushandiswa. Ivo vanowanzotambura neakasiyana madhigirii ekukuvadzwa kwekutanga senge ruts, kuputika, kuraswa kwemafuta uye makomba 2 kusvika 3 makore mushure mekunge vavhurirwa traffic. Chokutanga pane zvose, isu tava kunzwisisa chikonzero chekukuvadza kuitira kuti tigone kunyora mushonga wakakodzera.
Matambudziko ekutanga aripo mumigwagwa mikuru yenyika yangu anosanganisira zvinotevera zvinhu:
(a) Kuwedzera kwakanyanya kwekuyerera kwetraffic kwakawedzera kuchembera kwemigwagwa mikuru yenyika yangu. Kugara uchiremerwa nemotokari uye mamwe mamiriro ezvinhu akawedzera mutoro mumigwagwa mikuru, izvo zvakakonzerawo kuwedzera kukuru kwekupfeka kwemigwagwa uye kukanganisa;
(b) Chiyero cheruzivo, tekinoroji uye mechanization yekugadzirisa migwagwa munyika yangu yakaderera;
(c) Iyo yemukati sisitimu yekugadzirisa nekugadzirisa migwagwa haina kukwana uye nzira yekushandisa iri kumashure;
(d) Hunhu hwevashandi vekuchengetedza kazhinji hwakaderera. Naizvozvo, zvichienderana nemamiriro azvino emigwagwa mikuru yenyika yangu, isu tinofanirwa kumisa zviyero zvekugadzirisa, nzira dzekuchengetedza, uye nzira dzekurapa dzakakodzera migwagwa yenyika yangu, kuvandudza huwandu hwese hwemamaneja ekugadzirisa, uye kuderedza mari yekuchengetedza. Naizvozvo, matanho ekugadzirisa migwagwa anobudirira ane kukosha kwakanyanya.
Kuvakwa kwe slurry sealing rori inoda zvakasimba zvinodiwa maererano nezvinodiwa. Kuvaka kunonyanya kutanga kubva kune maviri maficha evashandi uye michina michina pamwe nehunyanzvi maitiro:
(1) Kubva pamaonero evashandi nemidziyo yemuchina, vashandi vacho vanosanganisira kuraira uye vashandi vehunyanzvi, vatyairi, vashandi vanoita basa rekugadzira, kugadzira muchina, kuyedza uye kurodha, nezvimwewo. Chinhu chikuru chinoshandiswa mukuvaka maemulsifiers, pavers, loaders, transporters. nemimwe michina.
(2) Panyaya yezvinodiwa zvekushandiswa kwehunyanzvi hwekuita, kugadzirwa kwakakosha kwemigwagwa kunofanirwa kutanga kuitwe. Iyi nzira inoda kutanga yapedzwa, uye inonyanya kubata nekuremara kwakadai semakomba, makatsemuka, maslacks, madhaka, masaisai uye elasticity. Govera vanhu nezvishandiso zvinoenderana nemapoinzi akakosha. Danho rechipiri kuchenesa. Iyi nzira inoitwa pamwe chete nekugadzira kuti ive nechokwadi chekuvaka. Chechitatu, pre-wet treatment inoitwa, kunyanya kuburikidza nekudiridza. Kuwanda kwekudiridza kwakakodzera kuitira kuti pasave nemvura pamugwagwa. Chinangwa chikuru ndechekuona kuti slurry yakabatanidzwa kune yekutanga nzira yemugwagwa uye kuti slurry iri nyore kugadzira uye kuumba. Zvadaro mukugadzira nzira, zvinodikanwa kuti urembedze chimwiro chekugadzira, gadzirisa zipper yekumberi uye yakaunganidzwa yekubuda, tanga, vhura muchina wega wega wekubatsira, wedzera slurry kumugero wekugadzira, gadzirisa slurry kuenderana uye pave. Teerera kumhanya kwepavha paunenge uchigadzira kuti uve nechokwadi chekuti pane slurry muforoma yekugadzira, uye chenjerera kuichenesa kana ichinge yavhiringidzwa. Nhanho yekupedzisira ndeyekumisa traffic uye kuita yekutanga kugadzirisa. Chisimbiso chisati chaumbwa, kutyaira kunokonzeresa kukuvara, saka traffic inoda kumiswa kwenguva yakati rebei. Kana pane kukuvadzwa kupi nokupi, inofanira kugadziriswa nokukurumidza kudzivirira chirwere chacho kuti chisapararire.
