三.Non coagulation phenomenon
Phenomenon: Mushure mekuwedzera mvura yekudzikisa mumiriri, kongiri haina kusimba kwenguva yakareba, kunyangwe kwemasikati nehusiku, kana iyo pamusoro inoburitsa slurry uye inoshanduka yero brown.
Chikonzero chekuongorora:
(1) Yakawandisa dosage yemvura inoderedza mumiririri;
(2) Kushandisa zvakanyanya retarders.
Mitemo yekugadzirisa:
(1) Isingapfuuri 2-3 nguva inokurudzirwa dosage, kunyange zvazvo simba rakaderera zvishoma, kuderedzwa kwesimba remazuva makumi maviri nemasere, uye kuderedzwa kwesimba kwenguva refu kwakatonyanya kuderera;
(2) Mushure mekugadzirisa kwekupedzisira, zvakakodzera kuwedzera tembiricha yekurapa uye kusimbisa kudiridza nekurapa;
(3) Bvisa chikamu chakaumbwa uye uidururire zvakare.
四.Low intensity phenomenon
Phenomenon: Simba rakaderera zvakanyanya pane mhedzisiro yebvunzo yezera rimwe chete, kana kunyangwe kongiri yakagadzika, simba rakaderera zvakanyanya.
Chikonzero chekuongorora:
(1) Kuwedzeredza kwekuwedzera kwemhepo inopinza mvura yekudzikisa mumiririri inokonzeresa kuwanda kwemhepo mukongiri;
(2) Kudedera kusina kukwana mushure mekusanganiswa nemhepo inopinza mvura inoderedza mumiririri;
(3) Kwete kuderedza mvura kana kuwedzera mvura simende reshiyo panzvimbo;
(4) Wedzera huwandu hwe triethanol yakawedzerwa.
Mitemo yekugadzirisa:
(1) Kutora mamwe matanho ekusimbisa kana kudirazve;
(2) Simbisa positi yekudira vibration;
(3) Tora matanho ekugadzirisa zvikonzero zvataurwa.
五.Kukurumidza kurasikirwa kwekudonha
Phenomenon: Concrete inokurumidza kurasikirwa nekushanda kwayo, uye nemaminetsi ega e2-3 ekuwedzera mushure mekubudiswa kubva mutangi, kudonha kunoderera ne 1-50 mm, uye pane chinhu chakakosha pasi chinonyura. High slump concrete inonyanya kutarisana nechiitiko ichi.
Chikonzero chekuongorora:
(1) Mvura inoderedza maajenti ane hurombo hwekuchinjika kune simenti inoshandiswa;
(2) Mabhuru akaunzwa mukongiri anoramba achifashukira, zvichikonzera kubuda kwemvura, kunyanya kana uchishandisa mhepo inopinza mvura inoderedza vamiririri;
(3) High kongiri kusanganisa tembiricha kana tembiricha kwezvakatipoteredza;
(4) Kudonha kwekongiri kwakakwira zvakanyanya.
Mitemo yekugadzirisa:
(1) Tsvaga chikonzero uye tora matanho ekuchigadzirisa;
(2) Uchishandisa nzira yekusanganisa positi, iyo inoderedza mvura inowedzerwa 1-3 maminetsi mushure mekusanganisa kongiri kana kunyange isati yadururwa, uyezve yakasanganiswa;
(3) Ngwarira kusawedzera mvura.
六.Settlement joint
Mushure mekudururwa, pachava nekutsemuka kwakapfupi, kwakatwasuka, kwakafara, uye kusina kudzika mukongiri pamberi uye mushure mekutanga kugadzika.
Chikonzero chekuongorora:
Mushure mekuwedzera mvura inoderedza vashandi, konkrete inowedzera, haina kubuda ropa uye haisi nyore kugadzirisa zvachose, inowanzoonekwa pamusoro pesimbi simbi;
Mitemo yekugadzirisa:
Shandisa kumanikidzika kune kuputika kusati kwasvika uye shure kwekugadzirisa kwekutanga kwekrete kusvikira vanyangarika.
