Detachments nyob rau hauv block pob zeb tau pom nyob rau hauv clutches ntawm Cuzco thiab Ollantaytambo. Lub pob zeb exfoliates los ntawm qhov chaw, thiab tsis delaminate horizontally, diagonally los yog ntawm lwm cov ces kaum. Tsis muaj cov piv txwv ntawm pob zeb delamination nyob rau hauv cov duab - tsuas yog nyias txheej txheej poob tawm ntawm cov blocks zoo li cov plhaub.

Tsis tsuas yog ua cov blocks muaj cov duab convex, tab sis qhov "plhaub" tev tawm ntawm lawv qhov chaw, rov ua qhov curvature ntawm qhov chaw. Hauv cov pob zeb, cov txheej txheem feem ntau yog txheej txheej kab rov tav. Thiab thaum tso cov blocks txiav los ntawm cov pob zeb ntuj, cov neeg tsim kho tau sim taw qhia lub block raws nraim kab rov tav - qhov no yog li cas lub block muaj lub zog loj tshaj plaws. Nrog rau kev sib txawv ntawm txheej txheej, nws tawg sai dua.

Arcuate detachments tsis cais. Tab sis tsis yog tsis muaj kev zam nyob rau hauv tag nrho cov blocks.

Delamination zoo ib yam li plaster tawg. Tab sis nws muaj tib xim thiab hom tib yam tsiaj raws li qhov thaiv nws tus kheej. Cov delaminations zoo ib yam li cov kev ntxhov siab hauv zos hauv pob zeb, los yog, kev ntxhov siab thiab cov kab mob hauv thaj tsam ze ntawm cov blocks. Thiab qhov no yuav yog qhov teeb meem - yog tias qhov ntim ntawm qhov thaiv nyob rau hauv qhov chaw no hloov nws qhov loj nyob rau hauv kev coj ntawm kev nce.

kuv twb muab tso tseg lawm tsab xov xwm nrog versionpiav qhia txog cov laj thawj rau qhov nce ntawm qhov ntim ntawm cov pob zeb trowant. Nyob rau hauv luv luv, vim li cas tej zaum yuav muab zais nyob rau hauv lub xub ntiag ntawm bentonite av nplaum nyob rau hauv lub composition ntawm pob zeb. Thaum noo noo nkag mus rau hauv, lub pob zeb maj mam, tab sis tseem loj tuaj. Pob zeb delamination kuj tshwm sim ntawm trovants. Tib lub tshuab tuaj yeem yog nyob rau hauv cov ntaub ntawv ntawm delamination ntawm blocks ntawm polygonal masonry.

Kuv cov lus piav qhia luv luv (rau cov neeg uas tab tom nyeem tsab xov xwm no thawj zaug los ntawm cov xov xwm hais txog polygonal masonry siv thev naus laus zis): cov masonry tau molded los ntawm cov khoom siv yas, geo-concrete (los yog, raws li kev tshawb fawb tshawb fawb, cov kua dej txias), uas yav tas los tshwm sim los ntawm plab hnyuv. Tam sim no lub plab nyob rau hauv tus txheeb ze nyob ntsiag to thiab zoo li phenomena tsis tshwm sim, nrog tsawg tshwj xeeb, thiab ces nyob rau hauv daim ntawv ntawm av nkos volcanoes.

Cov ancients pom hais tias lub pob zeb tig mus rau pob zeb nyob rau hauv lub sij hawm (tej zaum ntawm kev sib cuag nrog CO2 nyob rau hauv cov huab cua), thawj zaug ua npog nrog ib tug crust. Vim tej pob zeb yog vapor-permeable, ces pob zeb tsim kuj tshwm sim hauv, tab sis qeeb dua. Vim tias muaj qee feem pua ntawm cov bentonite av nplaum hauv cov pob zeb yas, cov pob zeb hauv cov masonry nthuav dav, ua convex thiab seam ntawm lawv xyaum ploj mus.

Thaum noo noo poob rau hauv lub qhov hws ntawm qhov thaiv - yog hais tias lub puab loj tseem tsis tau tag nrho petrified - nws nias rau ntawm txheej txheej. Thiab cov los ntawm lub sij hawm ntawd twb tau hloov mus rau hauv ib tug khoom yug me nyuam, uas exfoliated zoo li lub plhaub. Hauv luv, ib yam li ntawd.

Blocks ntawm qhov sib txawv ntxoov. Tej zaum muaj ob peb qhov chaw ntawm geo-pob zeb.

Daim duab no muab rau kuv lwm version. Nws yog tau hais tias cov formwork nyob rau hauv uas cov blocks tau molded (qhov tseeb lawv yog shields) yog coated nrog ib yam dab tsi nyob rau hauv daim ntawv ntawm zoo tib yam av nplaum (kom zoo dua sib cais los ntawm cov blocks). Qhov no yog qhov peb ua nyob rau hauv kev tsim kho, thaum concreting vaj tse - peb coated lub formwork nrog ib tug tshwj xeeb lubricant.

Muaj qhov sib txawv ntawm qhov sib xyaw ntawm cov av nplaum no nrog geo-concrete mus rau qhov tob. Lub pob zeb hloov nws cov khoom, txo lub zog, thiab thermal volumetric expansion ntawm txheej no hloov. Thiab nrog qhov kub thiab txias, txheej txheej no pib tev tawm maj mam. Cov txheej saum npoo no txawm sib txawv ntawm cov xim ntawm lub pob zeb sab hauv. Nws yog clayey ntau.

Qhov no yog ib qho pov thawj ntxiv nyob rau hauv piggy bank ntawm lub version hais txog lub tshuab ntawm kev tsim xws li masonry los ntawm tej yam ntuj tso geo-pob zeb.
