Indawo yokufakelwa kweepali zokujonga ividiyo

Ukukhethwa kweipali yokujonga ividiyoamanqaku kufuneka athathele ingqalelo izinto ezichaphazela okusingqongileyo:

(1) Umgama phakathi kwamanqaku eepali akufuneki ube ngaphantsi kweemitha ezingama-300 ngokomgaqo.

(2) Ngokomgaqo, umgama osondeleyo phakathi kwendawo yepali kunye nendawo ekujoliswe kuyo ukubekwa esweni akufuneki ube ngaphantsi kweemitha ezi-5, kwaye umgama okude akufuneki ube ngaphezulu kweemitha ezingama-50, ukuqinisekisa ukuba umfanekiso wokubekwa esweni unokuba nolwazi oluxabisekileyo ngakumbi.

(3) Apho kukho umthombo wokukhanya kufutshane, kungcono ukusebenzisa umthombo wokukhanya, kodwa kufuneka kuqatshelwe ukuba ikhamera kufuneka ifakwe kwicala lomthombo wokukhanya.

(4) Zama ukuphepha ukufaka kwiindawo ezine-contrast ephezulu. Ukuba kuyimfuneko ukufaka, nceda uqwalasele oku:

① Vula imbuyekezo yokuchatshazelwa (isiphumo asibonakali);

② Sebenzisa isibane sokugcwalisa;

③ Beka ikhamera ngaphandle komnyango kunye nokuphuma kwetonela engaphantsi komhlaba;

④ Yibeke kancinci ngaphakathi kwipaseji.

(5) Ingongoma yepali kufuneka ibe kude kakhulu nemithi eluhlaza okanye ezinye izithintelo kangangoko kunokwenzeka. Ukuba kuyimfuneko ukufakela, kufuneka ibe kude nemithi okanye ezinye izithintelo, kwaye ishiye indawo yokuba imithi ikhule kwixesha elizayo.

(6) Ngexesha lophando, kufuneka kuqwalaselwe ukufumana umbane kwiimashini zemiqondiso zamapolisa ezithuthi, iibhokisi zokusasaza izibane zesitalato, urhulumente, kunye namashishini amakhulu kunye namaziko (afana namasebe karhulumente, iinkampani zeebhasi, amaqela okubonelela ngamanzi, izibhedlele, njl.njl.) ukuze kube lula ukulungelelanisa nokuphucula uzinzo lokusetyenziswa kombane. Abasebenzisi abancinci bezorhwebo, ingakumbi abasebenzisi bezindlu zokuhlala, kufuneka baphetshwe kangangoko kunokwenzeka.

(7) Iikhamera ezisecaleni kwendlela mazifakwe ingqalelo ekuthatheni iimpawu zobuso zabahambi ngeenyawo nabahambi ngeenyawo kwindlela yezithuthi ezingenanjini.

(8) Iikhamera ezifakwe kwiindawo zokumisa iibhasi kufuneka zibekwe ngasemva kwesithuthi kangangoko kunokwenzeka, ziphephe izibane zemoto, ukuze zibambe abantu abangena ebhasini. Kufuneka kuqatshelwe ukuba iinkcukacha zokufakwa kweepali zokujonga ividiyo zifuna iintonga zombane kunye nokhuseleko olwaneleyo lokumisa umhlaba. Ukufaka isiseko se-lead yeyona ndlela ilungileyo; kuyacetyiswa ukuba iingcingo zingadluli emzimbeni wepali. Ke ngoko, kuyimfuneko ukumisela umgangatho kwaye ufake izixhobo zokuthintela umbane ezifanelekileyo kwiimpawu ezahlukeneyo ukuqinisekisa ukusebenza okuqhelekileyo kwexesha elide kwezixhobo zangaphambili. Ikhamera ifakwe emzimbeni wepali. Ukuba imeko yomhlaba kwindawo ilungile (ngezinto ezimbalwa ezingahambisi umbane ezifana namatye nesanti), umzimba wepali ungabekwa ngokuthe ngqo. Umgodi we-2000×1000×600 mm kufuneka umbiwe, kwaye umzantsi womngxuma kufuneka uzaliswe ngumhlaba ocolekileyo we-85% okanye umhlaba omanzi. Gcwalisa umngxuma ngomhlaba ocolekileyo uze emva koko ugqume ngokuthe nkqo i-rebar ye-1500 mm x 12 mm. Galela ikhonkrithi. Nje ukuba ikhonkrithi iphume, faka iibholithi ze-anchor (ezilungisiweyo ngokwemilinganiselo yesiseko sepali). Enye yeebholithi inokudityaniswa kwi-rebar ukuze isebenze njenge-electrode yokumisa umhlaba. Emva kokuba ikhonkrithi izinze ngokupheleleyo, gcwalisa ngomhlaba ocolekileyo, uqinisekise ukuba inqanaba lokufuma liphakathi. Okokugqibela, hlanganisa iingcingo zokumisa umhlaba zekhamera kunye ne-lightning arrester ngqo kwi-electrode yokumisa umhlaba epalini. Nika uthintelo lokugqwala kwaye uncamathisele ipleyiti yegama kwi-electrode yokumisa umhlaba. Ukuba imeko yomhlaba kwindawo ayilunganga (eneengxinaniso eziphezulu zezinto ezingezizo ezihambisa umoya ezifana nelitye nesanti), sebenzisa izinto ezonyusa indawo yoqhagamshelwano lwe-electrode yokumisa umhlaba, ezifana nezinciphisi zokungqubana, intsimbi ethe tyaba, okanye intsimbi ye-angle.

Amanyathelo Athile: Umsebenzi wokuqala unjengoko kuchaziwe apha ngasentla. Ngaphambi kokuba ugalele isiseko sekhonkrithi, beka umaleko we-chemical friction reducer onobukhulu obuyi-150 mm ecaleni kodonga lomngxuma uze ufake intsimbi ye-angle engama-2500 x 50 x 50 x 3 mm ngaphakathi komaleko. Sebenzisa intsimbi ye-flat steel engama-40 x 4-intshi ukuyitsala phantsi kwepali ethe nkqo. Iintambo zokumisa umbane kunye nekhamera kufuneka zifakwe kakuhle kwintsimbi ye-flat. Emva koko zidibanise intsimbi ye-flat kwintsimbi ye-angle (okanye isinyithi) phantsi komhlaba. Isiphumo sovavanyo lokuxhathisa ukumisa umhlaba kufuneka sihlangabezane nomgangatho wesizwe kwaye sibe ngaphantsi kwe-10 ohms.

Oku kungasentla yiloo nto uQixiang,Umenzi weepali zentsimbi waseTshayina, itsho njalo.
