Kuzama kophatikizika kwa chosungirako kudzakwaniritsa zofunikira zamapangidwe, ndipo kuya kophatikizidwa kudzakwaniritsa izi:
1. Pamene chosungiracho chimakwiriridwa mu nthaka youma kapena madzi osaya, chifukwa chosasunthika pansi, kuya kwa maliro kuyenera kukhala 1.0-1.5 nthawi zakunja kwa casing, koma osachepera 1.0m;kwa wosanjikiza pansi permeable monga mchenga ndi silt, kukwiriridwa kuya n'chimodzimodzi pamwamba, koma m'pofunika kuti m'malo ndi nthaka wosanjikiza osachepera 0.5m pansi pa m'mphepete mwa chubu zoteteza, ndipo m'mimba mwake ayenera kupitirira m'mimba mwake wa chubu zoteteza ndi 0.5-1.0m.
2. M'madzi akuya ndi m'mphepete mwa mitsinje dothi lofewa ndi dothi lakuda la silt, m'mphepete mwa chubu chotetezera chiyenera kulowa mkati mwa wosanjikiza wosanjikiza;Ngati palibe wosanjikiza wosanjikiza, uyenera kulowa 0.5-1.0m pamiyala yayikulu ndi nsangalabwi wosanjikiza.
3. Pa mitsinje yomwe ikukhudzidwa ndi kukwapula, m'mphepete mwa chubu chotetezera kuyenera kulowa osachepera 1.0m pansi pa mzere wa scour.Kwa mitsinje yomwe yakhudzidwa kwambiri ndi scour wamba, m'mphepete mwa chubu loteteza liyenera kulowa osachepera 1.0m pansi pa mzere wa scour.
4. M'malo a dothi owumitsidwa nthawi ndi nthawi, m'mphepete mwa chubu chotetezera kuyenera kupitirira 0.5m mu dothi losazizira pansi pa mzere wozizira;m'madera permafrost, m'mphepete pansi pa chubu zoteteza ayenera kulowa mu permafrost wosanjikiza zosachepera 0,5 m.0.5m .
5. M'malo owuma kapena madzi akuya ndi osakwana 3m ndipo palibe dothi lofooka pansi pa chilumbacho, chosungiracho chikhoza kukwiriridwa ndi njira yotseguka, ndipo dothi ladongo lidzadzazidwa pansi ndi kuzungulira. chosungiracho chiyenera kuphatikizidwa mu zigawo.
6. Pamene thupi la silinda liri lochepera 3m, ndipo dothi la silt ndi lofewa pansi pa chilumbacho silili wandiweyani, njira yokwirira yotseguka ingagwiritsidwe ntchito;Pamene nyundo ikumira, malo a ndege, kupendekeka kwake ndi khalidwe la kugwirizana kwa casing liyenera kuyendetsedwa mosamalitsa.
7. M'madzi omwe madzi akuya ndi aakulu kuposa 3m, chotetezera chotetezera chiyenera kuthandizidwa ndi nsanja yogwirira ntchito ndi chimango chowongolera, ndipo njira zogwedeza, kugwedeza, kugwedeza madzi, ndi zina zotero ziyenera kugwiritsidwa ntchito kuti zimire.
8. Pamwamba pa chosungiracho chiyenera kukhala 2m kuposa msinkhu wa madzi omanga kapena madzi apansi, ndi 0.5m pamwamba kuposa malo omangapo, ndipo kutalika kwake kuyenerabe kukwaniritsa zofunikira za kutalika kwa matope mu dzenje.
9. Kwa chubu chotetezera chomwe chilipo, kupatuka kovomerezeka kwa pamwamba ndi 50mm, ndipo kupatuka kovomerezeka ndi 1%.
