Kutshanje, uxwebhu oluqhelekileyo lwe- "JINBIAOTTechnical Requirements for Metal Sound Barriers" ebhalwe yi-Hengshui City Market Supervision Bureau, i-Hebei Jinbiao Building Materials Technology Co., Ltd. kunye ne-Hebei Wire Mesh yoMgangatho weMveliso kunye neZiko lokuHlola livunyiwe, ngo-Agasti 2019 Ukuphunyezwa yaqala nge 1st.
Lo mgangatho uquka imiqathango ngokubanzi kunye neenkcazo zemiqobo yesandi sesinyithi, iinkcukacha, iimfuno zobugcisa, iindlela zokuvavanya njalo njalo.Ifanelekile kwizithintelo zesandi zetsimbi ezisetyenziselwa ukunciphisa impembelelo yengxolo kwindawo ye-acoustic yeendawo ezibuthathaka ngexesha lokusasaza ingxolo.Ngokuqhelekileyo iqulunqwe ngumzimba wesikrini, amalungu axhasayo kunye neendawo eziyimfuneko zokuxhuma.
La maxwebhu alandelayo ayimfuneko ekusetyenzisweni kolu xwebhu.Kwiimbekiselo zomhla, yinguqulelo yomhla kuphela esebenzayo kolu xwebhu.Kwiimbekiselo ezingenamhla, uhlelo lwamva nje (kuquka zonke izilungiso) lusebenza kolu xwebhu.

Umgangatho usekelwe kulungiselelo olwaneleyo, iteknoloji evuthiweyo kunye nenkqubela phambili, zonke izibonakaliso zobugcisa zisayensi kunye nengqiqo, amanyathelo obugcisa abanzi kwaye achanekileyo, kwaye inqanaba lobugcisa likhokela ngaphakathi.
Isithintelo sesandi sentsimbi siye saba yindawo yokunciphisa isandi kunye nesandi esikhuthazwa kwaye sisetyenziswe kummandla waseBeijing-Tianjin-Hebei.Ngaphambili, kwakungekho mgangatho ocacileyo wenkcazo yentsimbi yesithintelo sesandi, kwaye kwakungekho ndlela yokulinganisa umgangatho wemveliso.Iinkcukacha zesithintelo sesandi sentsimbi zichazwe kolu xwebhu.ipharamitha:
Ukuphunyezwa kolu xwebhu oluqhelekileyo lubonelela ngesiseko sokulawula kunye nokuphucula umgangatho weemveliso zokuthintela isandi sesinyithi kummandla waseBeijing-Tianjin-Hebei.
Ngokwesaziso somgangatho wengingqi esikhutshwe liziko lephondo, imigangatho emithandathu yeSixeko saseHengshui yamkelwa njengemigangatho yendawo yePhondo laseHebei, apho i-5 yayiyimigangatho yoshishino lwe-mesh, ukongeza kwi "IiMfuneko Jikelele zobuGcisa kwiZithintelo zeMetal Sound" zichazwe. apha ngasentla, Ezi zinto "IiMfuneko Jikelele zobuGcisa kwiNcingo yeNsimbi (iRebar) iWelded Wire Mesh", "IiMfuno zobuGcisa ngokuBanzi kwiNtetha yeNsimbi eqhagamshelwe kwiNtyantyambo yentsimbi (iRhombus Net)", "IiMfuneko Jikelele zobuGcisa kwi-Aluminiyam Plate Tensile Decoration Net", kunye " IiMfuno zoBuchule ngokuBanzi kwiSikhewu seAluminiyam yefestile”.Kukholelwa ukuba ukuphunyezwa kwale migangatho kuya kukhuthaza kakhulu amandla othetha-ntengiso amashishini ane-wire mesh kunye nokwandisa isabelo sabo semarike.
