(一) Settlement Majoini
Chiitiko:Mazhinji mapfupi, akatwasuka, akafara uye asina kudzika akatsemuka achaonekwa mukongiri yakadururwa isati yatanga uye mushure mekutanga.
Chikonzero:Mushure mekuwedzera mvura-inoderedza mumiririri, kongiri inowedzera viscous, haina kubuda ropa uye haisi nyore kunyura, uye inowanzoonekwa pamusoro pesimbi.
Solution: Shandisa kumanikidzika kune kuputika pamberi uye shure kwekugadzirisa kwekutanga kwekrete kusvikira kuputika kwapera.
(二) Sticky Cans
Chiitiko:Chikamu chedhaka resimende chinonamira kumadziro emusanganisi, zvichiita kuti kongiri inobuda mumushini ive isina kuenzana uye shoma madota.
Chikonzero:Kongiri inonamira, inowanzoitika mushure mekuwedzera kudzoreredza-kudzikisa mvura musanganiswa, kana mumadhiramu musanganiswa ane yepedyo shaft dhayamita reshiyo.
Solution:1. Ngwarira kubvisa kongiri yakasara munguva. 2. Kutanga wedzera aggregate uye chikamu chemvura uye sanganisa, wobva wawedzera simenti, yakasara mvura uye mvura inoderedza agent uye sanganisa. 3. Shandisa musanganisi ane shaft yakakura dhayamita reshiyo kana musanganisi anomanikidzirwa
(三) Nhema Coagulation
Chiitiko:Kongiri inokurumidza kurasikirwa nemvura mushure mokusiya muchina uye haigoni kunyange kudururwa.
Chikonzero:1. Kusakwana calcium sulfate uye gypsum zviri mu simenti zvinokonzera calcium aluminate kuti hydrate nekukurumidza; 2. Mushonga wekudzikisa mvura une hutsika husina kunaka kune rudzi urwu rwesimende; 3. Kana zvinyorwa zve triethanolamine zvinodarika 0.05-0.1%, gadziriro yekutanga ichakurumidza. Asi kwete yekupedzisira.
Solution:1. Shandura rudzi rwesimende kana nhamba yebatch. 2. Shandura rudzi rwekudzikisa mvura kana zvichidikanwa, asi kazhinji hazvidiwi. 3. Deredza kuderedzwa kwemvura nehafu. 4. Deredza kupisa kwekusanganiswa. 5. Shandisa Na2SO4 kuti udzore zvinyorwa zvekugadzirisa ku 0.5-2%.
(四)Hapana Coagulation
Phenomenon: 1. Mushure mekuwedzera mvura-inoderedza mumiririri, konkrete haina kusimba kwenguva yakareba, kunyange masikati neusiku; 2. Paso pacho panoita manyemwe uye kuita yero.
Chikonzero:1. Muyero wemvura inoderedza mumiririri yakakura zvikuru, iyo inogona kudarika 3-4 nguva inokurudzirwa dosage; 2. Kunyanya kushandisa retarder.
Solution:1. Usapfuure muyero wakakurudzirwa 2-3 nguva. Kunyange zvazvo simba racho rakaderedzwa zvishoma, simba re28d richaderedzwa zvishoma uye simba renguva refu richaderedzwa kunyange zvishoma. 2. Mushure mekugadzirisa kwekupedzisira, wedzera kupisa kwekugadzirisa zvakakodzera uye kusimbisa kudiridza nekurapa. 3. Bvisa chikamu chakaumbwa uye uidururire zvakare.
(五) Low Intensity
Chiitiko:1. Simba rakanyanya kuderera kudarika miedzo yenguva imwe chete; 2. Kunyange zvazvo kongiri yakasimbiswa, simba rayo rakaderera zvikuru.
Chikonzero:1. Kuwanda kwemhepo-inopinza mvura-inoderedza mumiririri yakakura zvikuru, zvichiita kuti mhepo yemukati mukrete ive yakakura. 2. Kudedera kusina kukwana mushure mekuwedzera mhepo-inopinza mvura-inoderedza mumiririri. 3. Mvura haina kuderedzwa kana chiyero chemvura-samende chinowedzerwa panzvimbo. 4. Nhamba ye triethanolamine yakawedzerwa yakakura zvikuru. 5. Unhu hwemugadziri wemvura-kuderedza hahukwanisi zvinodiwa, zvakadai sezviri mukati mezvigadzirwa zvinoshanda zvakanyanya kuderera.
Solution:1. Shandisa mamwe matanho ekusimbisa kana kudira zvakare. 2. Simbisa vibration mushure mekudira. 3. Tora chiito uchipikisa zvikonzero zvataurwa. 4. Ziva iyi batch yezvinoderedza mvura zvakasanganiswa.
(六) Slump Kurasikirwa Kwakanyanya Kunyanyat
Chiitiko:Kongiri inorasa kushanda nekukasira. Ese 2-3 maminetsi mushure mekusiya tangi, kudonha kunoderera ne 1-2cm, uye pane zviri pachena pasi pekunyura chiitiko. Ichi chiitiko chinowanzoitika mukongiri nekudonha kukuru.
Zvikonzero:1. Mushandi wekudzikisa mvura ane hurombo husina kunaka kune simenti inoshandiswa. 2. Mafuro emhepo anounzwa mukrete anoramba achiwedzera uye mvura inoputika, kunyanya kana uchishandisa mhepo-inopinza mvura inoderedza vamiririri. 3. Kongiri yekusanganisa tembiricha kana ambient tembiricha yakakwira; 4. Kongiri inodonha yakakura.
Solution:1. Ita chiito pamusoro pechikonzero. 2. Gamuchira post-kusanganisa nzira. Mushandi wekudzikisa mvura anofanira kuwedzerwa mushure mekusanganisa kongiri kwemaminitsi 1-3, kana kunyange asati adira, uye simbisa zvakare. 3. Chenjerera kusawedzera mvura.
