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) Mafuro akaunzwa mukongiri anoramba achifashukira, achikonzera 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 mekudirwa, pachava nekutsemuka kwakati kupfupi, kwakatwasuka, kwakafara, uye kusina kudzika mukongiri isati yatanga uye mushure mekutanga.

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.
