I-Advance ductule, I-Pipe Shed, ipayipi le-grout lokumba umhubhe

1. Incazelo elula:

Ipayipi elincane elithuthukisiwe liyindlela yenqubo yenqubo yokumbiwa komhubhe. Isetshenziswa kakhulu endaweni ephukile ebuthakathaka

ngesikhathi esifushane sokuzinza, ingxenye engcwatshwe engajulile, ingxenye yokucindezela ingxenye emnyango, ingxenye yesihlabathi songqimba,

ingxenye yesihlabathi namatshe amatshe, indawo ephukile yephutha nezinye izigaba. ukwesekwa kwangaphambili.

2. Ibanga:

Q195, Q235, SS400, S235, STK400

3. Umgomo wokusekela:

I-1) I-conduit encane ehamba phambili iyindlela ephumelela kakhulu yokwakha ewusizo yokusimamisa ubuso bokumba.

Ekwakhiweni kwe-rock strata ebuthakathaka futhi ephukile, ipayipi elincane elithuthukisiwe lidlala indima ekuqiniseni

i-rock stratum ekhululekile. Ngemuva kwe-grouting, ukuzinza kwedwala elizungezile elikhululekile nelibuthakathaka liyathuthukiswa, okuzuzisayo

ekuzinzeni kwetshe elizungezile ngemva kokumba kanye nokuqedwa kwesikhathi sokuqala sokusekela. , ukuze

idwala elizungezile ngeke liphazamiseke futhi lonakaliswe kuze kube yilapho liwa.

I-2) I-grouting encane yamapayipi ethuthukisiwe ifanele idwala elizungezile elibuthakathaka le-tunnel arch, ungqimba lomhlabathi ovulekile, ongahlangene,

ungqimba lwesihlabathi olunekhono elimpofu lokuzinza kanye netshe letshe eliphukile izinga letshe.
I-3 ) Isimo nokuzinza kwedwala elizungezile kungashintshwa ngokufaka i-grouting ngokusebenzisa i-conduit encane ethuthukisiwe.

Ngemuva kokuthi i-grouting ijovwe ekubunjweni okubuthakathaka noma okuxekethile noma ukuqhekeka kwedwala elizungezile eliphethe amanzi eliphukile,

ingaxhumana eduze futhi iqinise. I-slurry ithatha indawo yomswakama nomoya phakathi kwezinhlayiya zenhlabathi kanye nedwala

imifantu ngokugcwalisa, ukuhlukanisa, njll., bese ithatha indawo yayo. , Umzimba ohlanganisiwe onamandla aphezulu kanye nokungangeni kwamanzi okuhle

ukusebenza kuthuthukisa kakhulu idwala elizungezile elivulekile neliphukile. .

4. Ipharamitha:

Amapharamitha wokwakhiwa komsele omncane othuthukisiwe kufanele anqunywe ngokuya ngomngcele wokwakheka komhlaba

izimo zedwala elizungezile, isimo sedwala elizungezile, isimo sesakhiwo esisekelayo kanye nobukhulu be

ingxenye yomhubhe. Ngokuvamile, ukwakhiwa kwemigudu emincane ethuthukisiwe kumiswa eduze komugqa wekhonta yokumba ngaphakathi kwebanga elingu-120 degrees.

Ngaphansi kwezimo ezijwayelekile: ubude be-conduit encane L = ukuphakama kwesinyathelo esiphezulu + 2m. Ububanzi be-catheter encane: 38-50mm.

Ingxenye yangaphambili ye-conduit encane yenziwe ngesimo se-cone ngobude obungaba ngu-10cm, futhi i-hoop yensimbi enobubanzi obungu-6 ~ 8mm ihlanganiswe ekugcineni komsila.

I-engeli ye-extrapolation ngokuvamile ilawulwa ku-10 degrees kuya ku-15 degrees. Ukucindezela kwe-grouting kulawulwa cishe ku-2MP.

I-slurry diffusion radius ngokuvamile iyi-0.5m. Isivinini se-grouting silawulwa ku-50-100L/MIN. Ubude obugqagqene bomzila ngamunye omncane ojikelezayo kulawulwa ngaphakathi kwe-1m.

5. Ukukhiqiza:

1) Ngokuvamile, yenziwe ngamapayipi ensimbi ashiselwe noma angenamthungo anobubanzi obungu-38 ~ 50mm.
2) Yenza ukwakheka kwekhoni okungaba ngu-10cm ubude ekugcineni kwepayipi elincane, bese ushisela ihupu yensimbi enobubanzi obungu-6 ~ 8mm ekugcineni komsila.

Azikho izimbobo ezivulwa phakathi kuka-100cm ukusuka ekugcineni okungemuva, kanti ingxenye esele ihlelwa ngembobo echichimayo engu-6mm ububanzi obuyi-plum blossom engu-20 ~ 30cm.

6. Ukufakwa:

Indlela yokuhola noma eqondile yokuphusha ngaphakathi ingasetshenziswa.
I-1) Imigodi yokubhoboza nge-drill kagesi, ububanzi bomgodi bukhulu kuno-10-20mm we-diameter ye-conduit encane, futhi ukujula komgodi kuncike kubude bomsele.
2) Uma kunzima ukufaka i-catheter, sebenzisa i-pneumatic drill enomsebenzi we-jacking ukuvala i-casing.
3) Sebenzisa i-blower ukuze ukhiphe imfucumfucu emgodini.
I-4) Ukuphela kwe-catheter encane kuhlanganiswe ngentambo yekotini, ukuze i-catheter encane ihlanganiswe eduze nomgodi oboshiwe, futhi ichweba elingenalutho livinjelwe ngentambo yekotini.
I-5) Ngemuva kokuthi i-conduit encane ifakiwe, kufanele ivalwe ngokhonkolo ofuthwe ngaphakathi kwebanga elithile elizungezile. Ubukhulu be-spray bulawulwa ku-5-8cm.
