Inkqubo yolwakhiwo lwesiseko sekhonkrithi enganyangekiyo kubushushu, isicwangciso esitsha sesitovu sokuqhushumba ukutyhilwa kobugcisa ~

Inkqubo esisiseko yesicwangciso sekhonkrithi yesitovu somlilo esiqhumayo siqokelelwa kwaye sihlelwe ngumenzi wezitena eziphikisayo.

1. Inkqubo yokwakha yefomwork esisiseko yesitovu sokuqhushumba okushushu:

(1) Sebenzisa i-formwork yentsimbi edibeneyo ukuxhasa, kwaye iimbumba zokhuni zingasetyenziselwa ukuzalisa izikhundla zomphetho.

2

(3) Amalungu phakathi kweetemplates kufuneka atywinwe, kwaye ukuvuza kwe-slurry kunqatshelwe ngokungqongqo.

(4) Emva kokuba inkxaso yetemplate igqityiwe, khangela ukuba ubungakanani, ukuphakama, kunye nenkxaso yendawo yethemplate ichanekile, qinisekisa ukuba ukuqina kunye nokuzinza kwenkqubo yenkxaso kuyahlangabezana neemfuno zoyilo, kwaye emva koko uhlambulule ukungcola kwi-template. .

(5) Emva kokuba ithempleyithi ifanelekile, la manyathelo alandelayo kufuneka athathwe ukuqinisekisa uzinzo lwethemplethi esisiseko ngenxa yomthamo omkhulu wesitovu sokuqhushumba:

1) Isiseko kufuneka sixhaswe ngemigangatho emithathu yentsimbi ye-angle ukuxhasa umbhobho wokupholisa, i-formwork kunye nemivalo yensimbi, kunye nentsimbi ye-angle enobude obufanayo nobukhulu besiseko kufuneka buxhaswe malunga nesiseko sokuqinisa i-formwork.

2) Iibholiti kunye ne-angle yokudibanisa intsimbi ebekwe malunga nesiseko isetyenziselwa ukuqinisa isiseko sefomwork.

3) Iibholiti zoxinzelelo ezibekwe kwisiseko esizimeleyo kunye nesiseko iikholamu ezimfutshane nazo zisetyenziselwa ukuqinisa isiseko sefomwork.

2. Isiseko somqamelo wekhonkrithi okwaziyo ukumelana nobushushu:

(1) Ngaphambi kokwakhiwa kwe-cushion yekhonkrithi, isiseko kufuneka silinganiswe, kwaye umphezulu wesiseko kufuneka ucocwe emva kokulinganisa.

(2) Umgca wokutsalwa: khulula umgca oncedisayo wokwakha we-cushion yekhonkrithi kwaye uphawule ngokucacileyo.

(3) Ukulungiswa kwekhonkrithi: Landela ngokungqongqo umlinganiselo wezinto ezikrwada kunye nobungakanani bamanzi ongeziweyo kwincwadana yokwakha yekhonkrithi ukuxuba ngokulinganayo.

(4) Ngaphambi kokuba ikhonkrithi ixutywe, ii-drill zensimbi kufuneka zibekwe kwisiseko ukulawula ubukhulu bayo. I-mold side ye-concrete cushion layer iya kulungiswa ngeentsimbi zensimbi. Ngexesha lenkqubo yokugalela, i-vibrator iya kwakhiwa ukuze ingcangcazele ngokuxineneyo, kwaye ekugqibeleni i-trowel yomthi iya kusetyenziswa ukulinganisa umphezulu we-cushion layer. dibana ne.

3. Ulwakhiwo lwekhonkrithi ekwaziyo ukumelana nobushushu lwesiseko sesitovu sokuqhushumba:

Ukwakhiwa kwekhonkrithi ekwazi ukumelana nobushushu kufuneka kugqitywe kangangoko kunokwenzeka ngexesha elinye, ukungcangcazela kunye nokudibanisa ngelixa ugalela, kwaye akukho zixhobo zokwandisa zigcinwe.

(1) Ukwakhiwa kunye nokugalelwa kwekhonkrithi kufuneka kuqhutywe ngokwemigangatho, nganye inobunzima obuyi-300mm, kwaye ikhonkrithi yomgangatho ophantsi kufuneka igalelwe phambi kokusetwa kokuqala komgangatho ophezulu.

(2) Ikhonkrithi kufuneka ishukunyiswe kwaye ihlanganiswe de umphezulu uyeke ukutshona okucacileyo, ukuqhwala kunye nokukhukula.

(3) Ngexesha lenkqubo yokwakhiwa kwekhonkrithi, khangela itemplate, imivalo yentsimbi, imingxuma egciniweyo, iindawo ezifakelweyo kunye nokufakwa kwi-displacement, deformation okanye ukuvaleka nangaliphi na ixesha, kwaye wenze uhlengahlengiso kunye nonyango, kwaye kufuneka zilungiswe phambi kokuba isethi yekhonkrithi iphelele. .

(4) Emva kokuba ulwakhiwo lwekhonkrithi lugqityiwe kwaye luqinisekisiwe ukuba lufanelekile, ukulungiswa kuya kuqalisa. Ukunkcenkceshela okuphindaphindiweyo kunye nokugubungela kunye nokunyanga kufuneka kuqhutywe kwiiyure ze-12. Ngethuba lenkqubo, umswakama owaneleyo womgangatho wekhonkrithi kufuneka uqinisekiswe. Ixesha lokunyanga kufuneka lingabi ngaphantsi kweentsuku ezi-7 ezipheleleyo. Ngethuba lexesha lokunyanga, ukushisa kwendawo yekhonkrithi kuya kuhlolwa kwaye kubhalwe rhoqo.

4. Amanyathelo okupholisa kwikhonkrithi ekwaziyo ukumelana nobushushu:

Ngenxa yomthamo omkhulu wekhonkrithi ekwazi ukumelana nobushushu kwisiseko sesitovu esitshisayo, ukuze kuthintelwe ukwenzeka kokuqhekeka kwamaqondo obushushu, amanyathelo okuthoba ubushushu kufuneka amkelwe:

(1) Xa ulungiselela ikhonkrithi, yongeza i-slag Portland sement kunye ne-basalt / ilitye le-andesite ukuthoba ubushushu be-hydration.

(1) Imibhobho yokupholisa ifakwe ngaphakathi kwisiseko ukuze isasazwe ngokulinganayo ngesithuba esimalunga ne-2m.

(2) Iithemomitha ezimbini zifakwe kwisiseko, kwaye ubushushu bulinganiswa ngokweemfuno zenkcazo.

(3) Ngexesha lokunyangwa kwekhonkrithi ekwazi ukumelana nobushushu, yimboze ngefilimu yeplastiki kunye neengxowa ze-straw, kwaye wenze ukunkcenkceshela kunye nokunyanga ngokwemigaqo yokugcina indawo emanzi.
