Kuvaka kwakagadzirwa nesimbi kunotarisa pane zvinongedzo zvakawanda zvakaita sekushongedza mapini, kupenda bitumen, kusanganisa mvura, kugadzirisa mold, kudedera, kudzivirira kuburitswa kwemold, kuvimbisa saizi, uye kururama kwenzvimbo dzekuyera, uye kuita kwacho kunoitwa zvichienderana nezvinodiwa nemugadziri wezvinhu nefekitori yebhoyira.
1. Kuisa mbambo nekubata zvipikiri
Mvura isati yatanga kumanikidzwa, mapini ari munzvimbo dzakakodzera dzakadai semajoini ekushongedza enzvimbo yekudziya uye majoini ekushongedza pamwe chete uye majoini enzvimbo yekudziya panguva yekufambisa nekuisa anofanira kuzadzwa. Gadzirisa majoini uye bata zvipikiri kuti uve nechokwadi chekuti mapini akarongeka zvichienderana nehuwandu hwakagadzirwa. Usati wadira, isa pendi yeasphalt ine ukobvu hwe> 1mm pazvikamu zvese zvesimbi zvakaputirwa, zvipikiri nezvimwe zvinhu zvesimbi kana kuputira zvinhu zvinobvira.
2. Zvimisikidzo, kugoverwa kwemvura, kudzora kusanganisa
Zvinhu zvinoshandiswa zvinoyerwa uye mvura inogoverwa zvichienderana nezvinodiwa nebhuku remugadziri wezvinhu, uye munhu akasarudzwa ndiye ane basa rekuyera kwakarurama. Mvura inoshandiswa pakusanganisa zvinhu zvinokandwa inofanira kunge iri mvura yakachena (yakadai semvura yekunwa), ine pH ye6 ~ 8. Teerera kurongeka kwekuwedzera mvura nenguva yekusanganisa nekusanganisa. Hazvibvumirwi kuwedzera mvura paunoda, uye hazvibvumirwi kufambisa mberi kana kuwedzera nguva yekusanganisa zvisina kurongeka. Huwandu hwemvura hahufanirwe kuwedzerwa panzvimbo imwe chete, uye chinhu chinokandwa chinofanira kusanganiswa zvizere. Zvakakosha kuwedzera simbi kune chinhu chinokandwa panguva yekuwedzera mvura nekusanganisa, uye hachifanirwe kusanganiswa muma agglomerates.
3. Kudzora template
Kugadzira mold inokandwa inzira yakakosha zvikuru, uye mhando yeplate yemold inokanganisa zvakananga kunaka kwemold inokandwa. Kudzora template kunotarisa pakugamuchirwa kwekusimba kwayo uye kururama kwayo. template inofanira kunge yakasimba uye yakabatana zvakasimba kuti ive nechokwadi chekuti hapana kusuduruka kana kusuduruka panguva yekudurura. Mold yehuni inofanira kuiswa zvichienderana nehukuru hwejometri yemufananidzo wekuvaka uye ukobvu hwekudurura, yakagadzirwa uye yakaunganidzwa, uye interface yacho yakasimba. Mold yakagadzirwa netemplate ye15 cm uye sikweya yehuni, ine upamhi hwe ≤500mm; mold yakagadzirwa nechimiro chakasarudzika yakagadzirwa nesikweya yehuni uye yakafukidzwa nepamusoro. Bhodhi remasendimita matatu rakaiswa, pamusoro payo pakakweshwa nezvinhu zviviri zvinoburitsa kuti ive nechokwadi chekuti ukobvu hwemold inokandwa uye pamusoro mushure mekuvaka pakachena uye pasina kudonha. Fomu inofanira kuongororwa uye kugamuchirwa isati yagadzirwa.
4. Kudzora kudira
Pakudurura chinhu chinokandwa, kureba kwechikafu chimwe nechimwe kunodzorwa kusvika pa200 ~ 300mm, chikamu chine ukobvu hunopfuura 50mm chinodururwa nechinhu chinokandwa chinokandwa chinokandwa, uye nzira ye "kukurumidza kupinda nekunonoka" inoshandiswa kuzunguza nguva dzose panguva yekuzunguza kudzivirira kubatwa. Kune gomba repasi nekuzunguza kwekubuda kwemvura, nguva yekuzunguza yenzvimbo yega yega haifanirwe kureba zvakanyanya kudzivirira hupfu hwakatsetseka kuti husayangarara. Munguva yekuzunguza, tsvimbo inokandwa haifanirwe kurova template uye hook nail zvakanyanya. Pakudurura zvinhu zvinokandwa zvinopfuura 50mm ukobvu, nzvimbo inopfuura 10m2 inofanira kuvakwa panzvimbo mbiri panguva imwe chete; kuti ive nechokwadi chekuti zvinhu zvakasanganiswa zvinodururwa mukati menguva yakatarwa, kudurura zvikamu zvisingasviki 50mm ukobvu kunosarudzwa kuve kwekuzvienzanisa uye otomatiki Degassed self-flowing castable construction.
5. Kuchengetedzwa kwemajoini ekuwedzera
Nekuti chiyero chekuwedzera chechinhu chinokandwa hachienderane nechiyero chekuwedzera chesimbi, inenge hafu yesimbi. Kazhinji, kune nzira ina dzekugadzirisa kuwedzera kwechinhu chinokandwa: imwe ndeyekupenda pendi yeasphalt pamusoro pepini nesimbi, ukobvu hwacho hausi pasi pe1mm. Yechipiri chikamu chekudurura munzvimbo yakakura, chinodururwa mumabhuroko ega ega 800 ~ 1000 × 400, uye zvinhu zvinobatanidza chinhu zvinonamirwa kubva padivi kuti zvibve pachikamu chinokandwa. Yechitatu ndeyekuputira bepa re ceramic fiber rine ukobvu hwe 2mm pamusoro pehood, zvishandiso zvepipe, uye zvikamu zvesimbi zvinopinda mumadziro sezvisungo zvinokandwa. Chechina, banga rinogona kushandiswa kucheka mukaha wehafu-ukobvu panguva yekuvaka purasitiki, kana kuti gomba rinogona kuboorwa mupurasitiki kugadzirisa dambudziko rekuwedzera.
