Wadarta ballaarinta ee ugu wanaagsan (magdhowga caagga) soo saaraha iyo alaab-qeybiye

Wadarta ballaarinta

Wadajirka ballaarinta ayaa inta badan loo isticmaalaa dredgers-ka ku xidhma xargaha bamgariga yar-yar iyo dhuumaha, iyo in lagu xiro dhuumaha dusha sare. Dambe dartiis awgeed. Wadarta ballaarinta ah waxay leedahay saamaynta naxdinta leh ee naxdinta leh inta lagu gudajiro howlgalka waxayna door difaacdaa ka hortag qalabka.

Wadarta ballaarinta waa nooc ka mid ah tuubada tuubbada caagga ah oo leh dherer gaaban oo guud ahaan in ka yar 1m dherer ahaan. Waxaa loogu talagalay in lagu hor tago qiimeynno badan oo cadaadis ah. Kala-goysyada ballaarinta ayaa loo habeyn karaa oo loo dhisi karaa si loo hor tago cadaadis taban, sida "-0.1 MPA", iyo in la horkeeni karo cadaadiska taban, sida "-0.1 Mpa", sidaas darteed MPA ", sidaas darteed, sidaas darteed, sidaas awgeed ayaa lagu dabaqi karaa xaaladaha cadaadiska kala duwan.

Wadajirka ballaarinta ayaa leh soosocda noocyo: ballaarinta fidinta ibta naaska, fidinta birta ah ee loo yaqaan 'Sandwich' iyo wadajirka ballaarinta iyo ballaarinta dhimista dhallaanka.

Astaamaha

(2) Caabudicsicsic Iident
(3) dabaqa wanaagsan
(4) nuugista naxdinta wanaagsan

Cayayaanka farsamada

(1) Cabbirka casriga ah: 100 mm ~ 1300 mm
(2) Dhererka tuubada: 0.2 m ~ 1 m (dulqaad: ± 1%)

Isticmaal

Wadarta ballaarinta ah waa qayb muhiim ah oo loogu talagalay nidaamyada muhiimka ah ee hawada weyn ee jaranjarada (CSD) oo ay ku dabaqeyso nidaamka tuubooyinka biyaha, haweenka oo lagu rakibo nidaamka tuubbada, tuubada taranka, iyo kan dambe ee bamka, iyo nidaamka tuubbada tuubada. Kala-goysyada ballaarinta ee ay soo saartay CDSR ayaa si qoto dheer u aaminay dadka isticmaala gudaha iyo shisheeye.

Waa lagama maarmaan in fiiro gaar ah la siiyo xiriirka ka dhexeeya dhererka ballaarinta wadajirka ah iyo booska rakibaadda, maadaama ay la xiriirtay nolosha adeegga ee sheyga. Caadi ahaan dhererka isku-darka ballaarinta waa 0 ~ 5mm ka gaaban meesha lagu rakibay meesha lagu rakibay, iyo nadiifinta ugu badan ee rakibidda ugu badan kama badnaan doonto 10mm si aad u ballaariso wadajirka dheer (ku dhawaad 1m dherer). Haddii ay dhacdo in oggolaanshaha rakibaadda uu aad u ballaaran yahay, kala-goynta ballaarinta marwalba waa la fidin doonaa tanina waxay dhaawici kartaa qaab-dhismeedkeeda.

Xirmooyinka qalooca CDSR waxay si buuxda u hoggaansamaan shuruudaha ISO 28017-2018 "tuubooyinka tuubooyinka caagga ah iyo tuubooyinka tuubooyinka, silig, si loo xoojiyo codsiyada-qeexitaanka" iyo sidoo kale hg / t2490-2011
