Dulmar guud oo ku saabsan Usha Barroosinka ee R25 Is-qodista Godka ah ee Cirbadda
Ulaha barroosinka guud ahaan waxay ku habboon yihiin xoojinta taageerada godadka macdanta, godadka buundooyinka, ilaalinta jiirada wadada, iyo meelaha kale. Guud ahaan, godadka barroosinka waxaa lagu qodaa iyadoo la isticmaalayo qodis usha barroosinka ah, waxaana la dhigaa wakiilada barroosinka ee ku habboon (duubista budada resin). Kadib, qalabka sida qodista usha barroosinka waxaa loo isticmaalaa in lagu qodo usha barroosinka godka barroosinka, lagu walaaqo oo lagu xidho wakiilka barroosinka, ka dibna la isticmaalo qalab sida qodista usha barroosinka si loogu rakibo lowska; Usha barroosinka ee gacanta midig, oo sidoo kale loo yaqaan usha barroosinka birta ee isku-dhafan ee isku-midka ah, waxaa laga sameeyay bir bir ah oo la duubay oo sax ah (ama bidix), oo leh dunno joogto ah iyo dherer buuxa oo lagu dhejin karo lowska. Waxaa loo isticmaalaa iyadoo lala kaashanayo lawska saxanka barroosinka si loogu taageero tunnelka. Boolku waa badeecad beddelka ah oo ah boolka cajiinka la shiilay ee ka hortagga shiilan, oo leh waxqabad sare.

Astaamaha is-qoditaanka ul barroosinka godan ee grouting
1. Ammaan ah, la isku halleyn karo, oo waqti badbaadin kara.
2. Rakibaadda iyo hawlgalka fudud.
3. Doorashada qaybaha qodista ee xaaladaha dhulka ee kala duwan.
4. Shaqada xoqidda waxay la jaanqaadaysaa qodista ama ka dib qodista. Qodista waxay si wax ku ool ah u buuxin kartaa jabka.
5. Baararka barroosinka waa la jari karaa oo la dheereyn karaa marka la codsado, iyadoo la marinayo meelaha cidhiidhiga ah.
6. Waxay bixisaa cadaadis isku xidhnaan oo ka sarreeya tuubo bir ah oo siman iyadoo ku xiran dunta hirarka joogtada ah.
Faa'iidooyinka is-qoditaanka ul barroosinka godan ee grouting
1. Usha barroosinka godan ee is-qodista waxay qaadataa qalab tuubo bir ah oo aan lahayn derbiyo wanaagsan, habka sameynta dunta dusha sare oo degdeg ah, iyo agabyo qurux badan, taasoo gaareysa midnimada qodista, xoqidda, xidhitaanka iyo hawlaha kale ee usha barroosinka is-qodista.
2. Waxaa jira dalool dalool leh xoog xoog leh oo gelinta ah oo hor yaal usha barroosinka godan ee is-wada, kaas oo si fudud u geli kara noocyo kala duwan oo dhagaxyo ah iyadoo la adeegsanayo mashiinnada qodista dhagaxa guud.
3. Waxay leedahay dun caadi ah oo qaab-dhismeedka hirarka ah waxaana loo isticmaali karaa sidii ul qodis ah si loo dhammeeyo qodista godadka barroosinka iyadoo la adeegsanayo qayb qodis ah.
4. Jidhka usha barroosinka ee tuubada qodista looma baahna in la soo saaro, meesha bannaanna waxay u adeegi kartaa sidii kanaal grouting ah oo loogu talagalay grouting gudaha dibadda.
5. Xidhmada grouting-ku waxay ilaalin kartaa cadaadis adag oo grouting ah, waxay si buuxda u buuxin kartaa meelaha banaan, waxay hagaajin kartaa cufka dhagaxa jabay, suufka iyo lawska xoogga badan lehna si siman ayay u wareejin karaan cadaadiska dhagaxa qotoda dheer ee ku hareeraysan dhagaxa ku hareeraysan, iyagoo gaaraya yoolka ah in la is taageero oo u dhexeeya dhagaxa ku hareeraysan iyo usha barroosinka.
6. Iyada oo ay ugu wacan tahay shaqada saddexda hal ee noocan ah ee usha barroosinka, waxay samayn kartaa godad barroosin ah waxayna hubin kartaa saamaynta barroosinka iyo xoqidda iyada oo aan loo baahnayn farsamooyin gaar ah sida ilaalinta derbiga saqafka iyo xoqidda kahor inta lagu jiro dhismaha xaaladaha dhagaxa ee kala duwan ee ku xeeran.
