I kwabantu isihlabathi

Sand esintwini eside isetshenziselwe izinjongo ukwakhiwa, ngaphandle indlu is hhayi ncamashi ukwakha. Yena kabanzi lisetshenziswe ezomile ukwakhiwa Izingxube, ezidayiswa ezitolo noma njengoba isakhi for nokulungisa usimende nosimende. Ukwakhiwa isihlabathi sisetshenziswa kuye kwabantu bayo, isibonelo, uhlobo oluthile asetshenziselwa ukwakha nosimende wokwakha, abanye ukuze akhiqize screed ukhonkolo.

Sand - a nonmetallic, okuxekethile yokwakha ukuthungwa. Ngokuvamile, ingxube ubukhulu wokusanhlamvu 0,14-5 mm, okuyinto akhiwa ngesikhathi kubhujiswa amadwala emvelo. Kunezinhlobo eziningana izinhlobo isihlabathi. Basuke izimpawu okuqukethwe elikhethiwe izinhlayiya emihle ngobumba noma umane uthuli izakhi.

Njengamagugu ambiwa phansi amsulwa wabo, futhi eliphezulu kakhulu - lena emfuleni isihlabathi. Marine okubi nakakhulu, njengoba isivele ingxenye usawoti, okuyindawo zigezwe. Pit yesihlabathi idwala libhekene khona ngobumba okungafunwa, futhi kungakho izinga lomkhiqizo ngezansi kwesithombe. Sand ngokuvamile has ukwakheka: asebenza ngebhethri, feldspars, futhi ukungcola ngesimo silicates futhi ngebumba efanayo.

Ngoba izici zalesi yokwakha kukhona into efana kwabantu isihlabathi. Kulinganiselwa porosity isilinganiso. Ngokwesibonelo, grade esihle ifa Inkomba 0.75. Ubuningi ukwakhiwa isihlabathi, izinga layo njalo kunqunywa khona therein ngobumba. Abakhi bathanda ukusebenza nge ubumsulwa esiyingqayizivele - umkhiqizo River. It has a kwabantu 1.3 t. Per imitha cubic. I kwabantu of yesihlabathi okuqukethwe ubumba isivele ngaphezu 1.8 m. Emqulwini efanayo.

Lokhu kwaziswa oluyisisekelo kweminyaka eminingi usimende kanye nokusungulwa ukhonkolo. Kuyathakazelisa ukuthi isenzo yafuna laying imigwaqo, ne-ohlabayo ingilazi izihloko kanti kwezolimo.

Lapho kwakhiwa zibaluleke kakhulu kubo umqondo density, okuyinto isilinganiso nenqwaba isihlabathi ukuze umthamo yayo, it has a iyunithi yokukala: g / cm3, kg / M3. Yemvelo kwabantu ngobuningi isihlabathi kuyinto 1300-1500 kg / M3.

zokwakha Bulk, lesi sibalo variable futhi kuncike degree of compaction. Kuyaqondakala ukuthi esilinganayo umkhiqizo kuthatha inani elihlukile. Ubuningi isihlabathi engaphansi njalo ngomhla umswakama yimiphi zayo ezihlukahlukene kuthinte kwabantu ngobuningi. Ngezinye okusanhlamvu umswakama ephakeme imbozwe ungqimba amanzi ngokuvumelana nenani isihlabathi inyuka kakhulu. Lokho ngobuningi kwabantu isihlabathi oscillation nomswakama ku-akhawunti lapho kubalwa umthamo isihlabathi yenqwaba oyifunayo. Uma ungenalo acabangele leli isici, nosimende ngeke banetincwadzi ukuphepha margin futhi jikelele design ubunjiniyela ngeke eliphansi.

Manje ngokuyinhloko asetshenziswa anesihlabathi isihlabathi, akhiphe yayo ilula - ugeza isihlabathi inkwali. Lokhu kwenziwa ngendlela elandelayo: umthamo omkhulu wamanzi therefrom wageza ubumba nothuli.

ukwakha isihlabathi kwabantu kuncike isakhiwo okusanhlamvu. Ngokwesibonelo, izinga eliphezulu ubufakazi eqondile yokuthi njengengxenye okusanhlamvu yayo aminyene, onamandla namakhaza ashubisa nemithi. Lona impahla kanye Coefficient okusezingeni eliphezulu lubaluleke isakhiwo ezimweni eyiqhwa. He is isisekelo ephezulu amandla ezibonakalayo, hardiness kakhulu.

Ubuningi asebenza ngebhethri isihlabathi esimweni okuxekethile libhekene Inkomba 1500 kg / M3, kodwa kungandisa ukuba 1700 kg / M3. It libhekene okungcono izici ehlanzekile futhi wageza calcined impahla yemvelo ezomile. Uma kusetshenziswe ukwakhiwa ukuqinisekisa okusezingeni eliphezulu izici ehlanzekile yokuhlala. Kwabantu asebenza ngebhethri isihlabathi - ipharamitha kubaluleke kakhulu ukuthi kunakwe ngesikhathi kwakhiwa.
