Ubukhulu bomgangatho we-slabs

Izakhiwo zefowuni yokupaka phakathi kwezakhiwo zesakhiwo ekwakhiwa ziveliswe kwimveliso yekhonkrithi. Zenziwe nge-admixtures yekhonkrithi ukusuka kumanani amaninzi, uhlobo oluluhlu lwekhonkrithi lwakhiwo kunye nesakhiwo esixinayo, kunye nekhonkrithi eqinisiweyo. Isicelo esona sikhulu se- slab sisakhiwo sokuthwala inxalenye yeeplani ezingqamlekileyo zezakhiwo ezinkulu. Umthwalo osebenzayo kwimveliso akufanele udlule i-kPa e-6, xa ubunzima besakhiwo abuqwalaselwe. Ukubekwa kwe-slabs engundoqo yomhlaba kufuneka kwenziwe kwinqanaba (udonga) umgama ubuncinane ubuncinane be-150-200 mm, kunye nemeko enyanzelekileyo ukuba inkxaso iya kuba namandla kunemveliso ngokwayo.

Phakathi kweentlobo eziphambili zezakhiwo zokwakhiwa kokugqithiswa kwezi zinto zilandelayo:

• I-PPP - i-slabs eneekhonkco eziqinisiweyo.
• Ukubhankwa okanye ngeprofayile yomgca;
• Ezizenzekelayo (ezingenanto ezingundoqo);
• Monolithic.

Ukumakishwa kwamacwecwe angenanto kuthetha oku kulandelayo:

• I-1P - izitrakhthi ezizinzileyo zakhiwo kunye nobude be-120 mm;
• 2P - isitya esinye, kodwa ubukhulu obukhulu (160 mm);
• I-1PK - engenanto engundoqo (220 mm), ngaphakathi apho kukho i-void ngeenxa zonke ngobubanzi be-159 mm;
• 2PK - ipakiti enye, ububanzi bemigumbi - 140 mm;
• I-PB - indawo engapheliyo ye-220 mm, indlela yokwakha - ngaphandle kokusetyenziswa kwefom.

Iiplati ezigqityiweyo, ubukhulu obuphakathi kwemida yomgangatho, zihlala enye yezona nkcukacha zakhiwo ezifanelekileyo. Awuyikutshabalalisa, akayi kubola, ayenzileyo kwaye anokwethenjelwa, kwaye ayamelana nokunyamezela.

Ubuninzi beeplate ezigqithisiweyo ziquka iiparitha zeparalphapiped, ngaphakathi kwazo zikhona ngeefayili zombindi. Ubukho bezo zikhonkwane bunikeza isakhiwo isakhiwo esiqinileyo sokuguqa, esenza sikwazi ukujamelana nemithwalo ebalulekileyo. Ukongezelela, ukungahambi kakuhle kuququzelela inkqubo yokubeka kuwo onke amanxibelelwano enokwenzeka ngexesha lokwakha isakhiwo.

Ubukhulu bomgangatho obanzi be- slabs buyisiqinisekiso esiqinisekileyo seendleko ezaneleyo zokuveliswa kwemveliso yekhonkrithi. Nangona kunjalo, ukuyila kunye nobukhulu obungaphandle kwesiqhelo kungadalwa ngemifanekiso nganye. Nangona kungcono kumakhi wokonga ukuba asebenzise ubukhulu becala ngenxa yeendleko eziphezulu zokuvelisa ama-slabs angaqhelekanga ngenxa yeendleko ezongezelelweyo.

Ubungakanani obukhulu bomdaka obuncinane bomhlaba obunamagama abude ubude kumgama ukusuka kwi-2.4 ukuya kwi-6.6 m, exhomekeke kwikhathalogu kunye nechungechunge lomkhiqizo oqhelekileyo. Ububanzi obuqhelekileyo bunokuba yi-0,6 - 2,4 m ngexesha kunye namanyathelo ahlukeneyo. Ukuphakama (ubukhulu) bamacwecwe kumkelwe kwizinga le-220 mm, kwaye isisindo esipheleleyo semveliso yonke siyi-2.5 toni.

Ubungakanani bomhlaba obunobumba obuphambili obunobumba bubekwe ngokubhaliweyo ekumakeni kwemveliso nganye, kwaye kufuneka kuqondwe ngale ndlela, umzekelo, i-PC 72.15-8:

• I-PC ithetha oku kulandelayo: isitya esingundoqo esingqongqo esinamacala angama-159 mm, ubude obuphezulu be-220 mm, macala omabini anqwenela ukuba axhaswe;
• 72 - ubude bemveliso kwi-decimeters (oko kukuthi, kwiimitha-7180);
• 15 - ububanzi kwi-decimeters (okanye ibalwa ngama-1500 mm);
• 8 - umthwalo apho isitya singakwazi ukumelana, kwi-kPa.
