Ibisasu bikoreshwa cyane kuri gukurura ukuboko kwa suction yo gukurikira hopper (tshd) cyangwa urwego rukaze rwa theter Dredger (CSD). Ugereranije no gusohora amakara, amavuta yo guswera arashobora kwihanganira igitutu kibi usibye igitutu cyiza, kandi birashobora guhora mubikorwa mubihe bifatika. Ni amazu ya reberi ya reberi kuba dredger.

Ibiranga nyamukuru byo guswera hose ni kwambara ibintu byiza, kurwanya ikirere, no guhinduka.

Mubisanzwe igitutu kinini cyakazi cyo guswera amarurundo kiragera kuri -0.1 mPA, hamwe nigitutu cyikizamini ni -0.08 MPA. Ibisabwa byo guswera bifite ibisabwa bidasanzwe cyangwa byihariye, nkibishobora kwihanganira imikazo kuva kuri -0.1 mPA kugera kuri 0.5 MPA, nabyo birahari. Amakoro yasutse arakwiriye ubushyuhe bwibidukikije kuva muri -20 ℃ kugeza 50 ℃, kandi akwiriye gutanga imvange y'amazi (cyangwa amazi yinyanja) kuri 1.0 g / cm³.

Ibicuruzwa bya CDRR bishimangira ibisabwa byingenzi bya Iso28017-2018 hamwe nigipimo cyinganda za minisiteri inganda za minikile HG / T2490-2011, kandi irashobora kandi guhura nibicuruzwa bigezweho nibisabwa nibicuruzwa bifatika kubakiriya.

Dukurikije imiterere itandukanye, muri rusange hariho ubwoko bune bwa fses: guswera hose hamwe nicyuma, kurekurwa
