Ukukhetha i-diameter yangaphandle efanelekileyo ye-300 yemibhobho yentsimbi ibalulekile kwinkqubela phambili egudileyo yeeprojekthi zobunjineli. Ukukhethwa kobubanzi obungaphandle bemibhobho yensimbi ye-300 kubandakanya iinkalo ezininzi ezifana nokhuseleko, umthamo wokuthwala umthwalo, kunye nesiphumo sokusetyenziswa kweprojekthi. Ngoko ke, kufuneka kuqwalaselwe iinkalo ezahlukahlukeneyo ukuze kwenziwe isigqibo sobulumko.

Okokuqala, qonda uluhlu lwangaphandle lwedayimitha yeepayipi zentsimbi ezingama-300
Ububanzi obungaphandle bemibhobho yentsimbi engama-300 ngokuqhelekileyo ibhekisela kumgama osuka ngaphandle kodonga lombhobho ukuya ngaphandle kodonga lombhobho. Kukho iinkcukacha ezininzi eziqhelekileyo onokukhetha kuzo, ezinje nge-Φ48, Φ60, Φ89, njalo njalo. Xa ukhetha i-diameter yangaphandle ye-300 yemibhobho yentsimbi, kufuneka uqale uqonde uluhlu oluthile lwedayamitha yangaphandle ukuze wenze ukhetho olufanelekileyo kolona lulo. iprojekthi.

Okwesibini, misela ubungakanani bedayamitha yangaphandle ngokweemfuno zobunjineli
1. Iimfuno zomthamo wokuthwala umthwalo: Ukuba umbhobho we-300 wensimbi kufuneka uthwale ubunzima obukhulu okanye udlale indima exhasayo, kufuneka ukhethe inkcazo enkulu yangaphandle yobubanzi ukuqinisekisa ukuba inomthamo owaneleyo wokuthwala.
2. Izithintelo zendawo: Kwezinye iimeko zobunjineli ezikhethekileyo, kunokubakho izithintelo kwindawo yofakelo lombhobho. Ngeli xesha, kufuneka ukhethe ubungakanani bobubanzi obungaphandle ngokwemeko yangempela ukuqinisekisa ukufakwa kakuhle kombhobho.
3. Iimfuno zokuthutha ulwelo: Ukuba umbhobho we-300 wensimbi usetyenziselwa ukuthutha ulwelo, kuyimfuneko ukuqwalasela izinga lokuhamba kunye nesantya sokuhamba kwamanzi kwaye ukhethe ubungakanani obufanelekileyo bomdamitha wangaphandle ukuze kuncitshiswe ukuchasana nokuthuthwa kwamanzi kunye nokuphucula ukuhamba kakuhle.

Okwesithathu, bhekisa kwimigangatho efanelekileyo kunye neenkcukacha
Xa ukhetha i-diameter yangaphandle yombhobho wensimbi we-300, unokubhekisela kwimigangatho yelizwe, imilinganiselo yoshishino, kunye neenkcukacha zoyilo lobunjineli. La maxwebhu ahlala enika iziphakamiso zokusetyenziswa kwemibhobho yensimbi yenkcazo eyahlukeneyo kwiimeko ezahlukeneyo, ezinokuthi zisetyenziswe njengesalathiso sokukhetha ububanzi bangaphandle.

Okwesine, dibana neengcali
Ukuba unokungabaza xa ukhetha ububanzi obungaphandle bombhobho wensimbi we-300, unokuqhagamshelana neenjineli ezifanelekileyo okanye iingcali zetsimbi. Baza kunikela amacebiso asengqiqweni asekelwe kwiimeko zokwenyani kunye namava okusinceda senze izigqibo ezingcono.

Okwesihlanu, kuqwalaselwe ngokupheleleyo uqoqosho nokusebenza
Xa ukhetha ububanzi obungaphandle bombhobho wensimbi we-300, ngaphezu kokuqwalasela iimfuno zayo zokusebenza, kufuneka kwakhona uqwalasele uqoqosho lwayo kunye nokusebenza. Ngakolunye uhlangothi, qinisekisa ukuba i-diameter yangaphandle ekhethiweyo inokuhlangabezana neemfuno zeprojekthi, kwaye ngakolunye uhlangothi, zama ukugcina iindleko kwaye ugweme inkcitho yemithombo.
