Ukufakwa kwensimbi yensimbi, kufanele kuqala kudwebe uhlelo lwemishini yensimbi,Insimbi enezikhalalaying, isidingo sokuyeka ukubeka isiqondiso ngokuvumelana field theory kanye nemishini abasebenzi field ukusebenza kahle.Iziphetho ezimbili zenetha elishiselwe kufanele zigwazwe ogoqweni kanye ne-anchorage, lapho ukuqiniswa kwe-longitudinal kwe-mesh yensimbi kulungile, kusetshenziswa umsebenzi wokugoba we-mesh yensimbi, imaphakathi nenetha lokushisela kuqala ligoba phezulu, ngakho-ke. ukuthi zombili iziphetho zingagwazwa kugongolo, bese insimbi yensimbi ibushelelezi.
Lapho ibha yensimbi iyinetha eliqinile elishiselwe ayikwazi ukugoba, isiphetho senetha lokushisela singancishiswa kancane nge-1-2 bar yensimbi, bese kuthi imiphetho yomibili yesigxobo, kanye nebha eqondile kusetshenziswa indlela yokubopha isayithi, ukunciphisa ukuqinisa okuphambene, ukuqinisa okwengeziwe kanye nokuxhumeka kwenetha elishiselwe endaweni ngayinye kufanele kukhethwe ukubophezela kwensimbi yensimbi.
Insimbi enezikhalaUkukhethwa kwenetha eliphansi lokuhlelwa kokuqinisa ama-rack kanye nokuhlelwa kwenetha le-cushion yezindlela ezimbili, inetha le-rib reinforcement welding ye-two-way reinforcement kufanele kukhethwe i-flat lap joint, kufanele isethwe kumandla amancane, kufanele ihlukaniswe nohlangothi lwe-1/ I-4 net cross section, ubude bethanga akufanele bube ngaphansi kuka-30DD ngesiqondiso se-lap, ububanzi bensimbi futhi akufanele bube ngaphansi kuka-250mm.
Phakathi kwezingcezu ezimbili zenetha lokushisela, ithanga lensimbi elihlangene ubude bethanga elincane akufanele libe ngaphansi kwezikhathi ezingu-1.3 ubude be-anchorage encane la, futhi akufanele libe ngaphansi kuka-200㎜ endaweni ethangeni, ibha ngayinye yensimbi enensimbi enensimbi ephambanayo akufanele ibe ngaphansi. ngaphansi kokukodwa, anezikhala ezimbili zensimbi ngaphandle kwebanga lensimbi ephambanayo akufanele libe ngaphansi kuka-50㎜.Uma kungekho ukuqiniswa okuguquguqukayo kwensimbi enezikhala ezimbili endaweni ethangeni, ubude bethanga elincane lensimbi enezimbambo kufanele bube izikhathi ezingu-1.3 zobude obuncane be-anchorage LA, futhi akumele bube ngaphansi kuka-300㎜.Lapho ububanzi bokuqiniswa kwamandla e-longitudinal endaweni yethanga D ≥10㎜, ubude bethanga kufanele bukhuliswe ngo-5d.
Indlela yokuhlola yesikhathi esizayo yeInsimbi enezikhalaImishini: inqubo yokugandaywa kwensimbi enezikhala yile: insimbi enezikhala ezishiselwe kufanele ibekwe ngokuhambisana nomdwebo wokuklama - imishini ye-mesh - mesh - ukuhlolwa nokuhlolwa.Okulandelayo i-steel mesh pavement: indawo ephansi yempahla, inethi eyengeziwe noma izinto zensimbi, umgwaqo ogandaywe wenethiwekhi wokusekela, umgwaqo wenethiwekhi omile futhi ovundlile, inethiwekhi eyengeziwe nezinto zensimbi.
