Dulmar guud ee R25 Is-Drilling Godan Grout Irbadaha Barroosinka
Ulaha barroosintu waxay guud ahaan ku habboon yihiin xoojinta taageerada marinnada macdanta, tunnelyada buundooyinka, ilaalinta jiirka jidka, iyo meelaha kale.Guud ahaan, godadka ulaha barroosinka ah ayaa la qodaa iyadoo la isticmaalayo laydhka usha barroosinka ah, waxaana la dhigaa wakiilada ku haboon ee ku xidhidhiyaha ( duubabka budada resin)Kadibna, qalabyada sida daloolinta usha barroosinka ayaa loo isticmaalaa in lagu dalooliyo usha barroosinka ee daloolka usha barroosinka, walaaqa oo ku xidho wakiilka, ka dibna la isticmaalo aaladaha sida daloolinta usha barroosinka si loogu rakibo looska;Usha barroosinka ee gacanta midig, oo sidoo kale loo yaqaano xoogga siman ee dunta birta ah ee birta ah, waxay ka samaysan tahay midig (ama bidix) bir duuban oo saxan, leh dunyo joogto ah iyo dherer buuxa oo lagu dunsan karo lowska.Loo isticmaalo iyadoo lala kaashanayo nuts saxanka barroosinka taageerada tunnelka.Boolku waa badeeco beddel ah oo ka hortagta cajiinka la shiilay bolt, oo leh waxqabad heersare ah.

Astaamaha usha barroosinka ah ee iskeed wax u qodaya
1. Badbaado, la isku halayn karo, iyo waqti badbaadin.
2. Rakibaadda fudud & hawlgalka.
3. Doorashada meelaha laydhka ee xaaladaha kala duwan ee dhulka.
4. Shaqooyinka grouting waxay la midoobaan qodista ama qodista ka dib.Grout waxay si waxtar leh u buuxin kartaa jabka.
5. Biraha barroosinka waa la gooyn karaa waana la dheerayn karaa marka la codsado, iyadoo lagu dabaqayo meelaha cidhiidhiga ah.
6. Waxay bixisaa cadaadis isku xidhka ka sarreeya tuubada birta siman taas oo ku xidhan dun hirka joogto ah.
Faa'iidooyinka usha barroosinka is-qodidda godan
1. Usha barroosinka grouting godan oo is qodaya waxay qabataa walax bir ah oo dhumuc weyn leh, geeddi-socod samaynta dunta sare ee degdega ah, iyo agabka wanaagsan, gaaritaanka midnimada qodista, grouting, barroosinka iyo hawlaha kale ee usha barroosinka is- qodida.
2. Waxaa jira daloolin xoog leh oo xoog leh oo ka soo horjeeda usha barroosinka ah ee iskeed u godan, kaas oo si fudud u dhex geli kara noocyada kala duwan ee dhagaxyada iyada oo ay fulinayaan mishiinnada qodista dhagaxyada guud.
3. Waxa ay leedahay dunta mawjadeedka caadiga ah ee joogtada ah waxaana loo isticmaali karaa sidii ul daloolista si loo dhamaystiro qodista godadka barroosinka ee leh birta.
4. Usha barroosinka ee tuubada daloolku uma baahna in la soo saaro, bannaanka bannaanna wuxuu u adeegi karaa kanaalka grouting ee gudaha gudaha ka soo baxa.
5. Joojiyaha grouting wuxuu ilaalin karaa cadaadis xoog leh, oo si buuxda u buuxinaya nusqaamaha, hagaajinta xajmiga dhagaxa jaban, iyo suufka xoogga badan iyo lowska ayaa si siman u wareejin kara culeyska dhagaxa qoto dheer ee ku wareegsan dhagaxa ku hareeraysan, gaaritaanka hadafka labada dhinac. taageerada u dhaxaysa dhagaxa ku wareegsan iyo usha barroosinka.
6. Sababo la xiriira saddex in hal function of noocan oo kale ah usha barroosinka, waxa ay samayn kartaa godadka barroosinka iyo in la hubiyo in barroosinka iyo saamaynta grouting iyada oo aan baahida loo qabo farsamooyin gaar ah sida ilaalinta derbiga daas iyo pre grouting inta lagu guda jiro dhismaha hoos xaaladaha dhagaxyada kala duwan ee ku xeeran.
