Ukusetshenziswa kabanzi kwezindawo zokugcina izithombo kuye kwashintsha izimo ezikhulayo zezitshalo zendabuko, okwenza kube nokwenzeka ukutshala izitshalo unyaka wonke futhi kulethe imali eningi kubalimi.Phakathi kwazo, i-multi-span greenhouse iyisakhiwo esikhulu sokushisa, isakhiwo ngokuvamile siyinkimbinkimbi, futhi ukutshalwa kwezimali kukhulu kakhulu.Izindlu zokugcina izithombo ze-multi-span ezinkulu ngokuvamile zisetshenziswa njengendawo yokudlela yemvelo, izimakethe zezimbali, imibukiso yokubuka indawo noma izindawo zokugcina izithombo zocwaningo lwesayensi.I-greenhouse skeleton iyisakhiwo esiyinhloko samathambo amaningi we-greenhouse greenhouse skeleton.Ekuqaleni komklamo, kufanele sinqume ukuthi yiluphi uhlobo lohlaka lwe-greenhouse okufanele lusetshenziswe ngokuvumelana nezidingo ezithile.Yiqiniso, izinhlobo ezahlukene zamathambo abamba ukushisa zinezici ezihlukene zesakhiwo.Nasi ukwakheka kwe-greenhouse skeleton:
1.Yonke impahla yohlaka lwensimbi isetshenziswa njengohlaka lwamathambo abamba ukushisa, kanti umzimba oyinhloko we-greenhouse unokuphila okude kwenkonzo, kuze kube yiminyaka engaphezu kwengu-20.Kodwa ngesikhathi esifanayo, kubalulekile ukunaka ukugqwala nokuvikelwa kokugqwala kwefreyimu ye-greenhouse, ngokuvamile eyamukela uhlaka lwensimbi olushisayo olushisayo.
2.Uhlaka lwe-greenhouse lunokumelana okuqinile nomthwalo womoya kanye nomthwalo weqhwa.Ngokwemvelo yethu yendawo yemvelo, umoya, imvula neqhwa nezinye izimo zemithombo yemvelo, khetha uhlaka olufanele futhi umboze izinto ezihlukene.
3.Idizayini ye-Multi-span ingamukelwa, enendawo enkulu yasendlini kanye nezinga eliphezulu lokusetshenziswa komhlaba, elilungele ukutshala endaweni enkulu kanye nokusebenza ngomshini kwe-Goshen greenhouse.I-span ne-bay ingakhethwa.Ngakhe iphrojekthi ye-greenhouse ene-span enkulu kunazo zonke engu-16.0m kanye nechweba elingu-10.0m.Ngemuva kokuwa kweqhwa elinzima, uhlaka lwamathambo abamba ukushisa alushintshile futhi seluqoqe ulwazi olusha lokusetshenziswa kwamathambo abamba ukushisa.
Ngokuvamile, kusetshenziswa ifreyimu ye-greenhouse eboshiwe, elula futhi ethengekayo ukuze ifakwe futhi ihlale isikhathi eside.Uma i-welding isetshenziswa, i-welding kulula ukugqwala.Uma sekugqwalile, kuzothinta kakhulu impilo ye-greenhouse skeleton.Ngakho-ke, lapho ucubungula uhlaka lwe-greenhouse, sebenzisa izimbobo zembobo ngangokunokwenzeka ukuze ugweme ukushisela.Uhlaka lwe-greenhouse ene-span multi-span kufanele lwenziwe ngezinto ezifanele ngokuya ngendawo yensimu, futhi abaklami abangochwepheshe kufanele benze ukulinganisa nokuklama ukuze baqinisekise ukuthi indlu yokushisa eyakhiwe iqinile futhi ihlala isikhathi eside.
