I-advance ductule, iShedi yombhobho, umbhobho wegrout wokwembiwa kwetonela

1. Inkcazo elula:

Umbhobho omncinci ophucukileyo yindlela yenkqubo kwinkqubo yokwembiwa kwetonela. Isetyenziswa ikakhulu kwindawo ebuthathaka ephukileyo

kunye nexesha elifutshane lokuzinzisa, icandelo elingcwatywe elingenanto, icandelo loxinzelelo oluyinxenye ekungeneni, icandelo lesanti,

icandelo lesanti kunye neengqalutye, indawo ephukileyo kunye namanye amacandelo. inkxaso yangaphambili.

2. IBakala:

Q195, Q235, SS400, S235, STK400

3. Umgaqo wenkxaso:

I-1) I-conduit encinci ehamba phambili yindlela efanelekileyo kakhulu yokwakha yokuncedisa ukuzinzisa ubuso bokumba.

Kulwakhiwo olubuthathaka kunye noluqhekekileyo lwamatye, i-conduit encinci ehamba phambili idlala indima ekomelezeni

i-rock stratum ekhululekile. Emva kwe-grouting, ukuzinza kwelitye elijikelezileyo kunye nobuthathaka kuphuculwe, okuluncedo

ukuzinza kwelitye elijikelezileyo emva kokumba kunye nokugqitywa kwexesha lokuqala lokuxhasa. , ukuze i

iliwa elijikelezileyo aliyi kuphazamiseka kwaye lonakaliswe de lidilike.

2) Umbhobho omncinci ophuculweyo ulungele ilitye elijikelezileyo elibuthathaka le-tunnel arch, ekhululekileyo, umaleko womhlaba ongabambekiyo,

umaleko wesanti onesakhono esilambathayo sokuzinzisa kunye nentlalutye (ingqalutye) kwinqanaba lelitye eliqhekekileyo.
I-3 ) Isimo kunye nokuzinza kwelitye elijikelezileyo kunokutshintshwa ngokugrumba nge-conduit encinci ehamba phambili.

Emva kokuba i-grouting ifakwe kwisakhiwo esibuthathaka okanye esixekileyo okanye ukuqhekeka kwelitye elijikelezileyo eliphethe amanzi,

inokunxibelelana ngokusondeleyo kwaye iqinise. Udaka luthatha indawo yokufuma nomoya phakathi kwamasuntswana omhlaba nasematyeni

Ukuqhekeka ngokuzalisa, ukwahlula, njl., kwaye emva koko ithathe indawo yayo. , Umzimba odibeneyo onamandla aphezulu kunye nokungena kwamanzi

ukusebenza kuphucula kakhulu ilitye elijikelezileyo kunye nelophukileyo. .

4. Ipharamitha:

Iiparamitha zokwakhiwa kombhobho omncinci ophezulu kufuneka zimiselwe ngokomda wejoloji

iimeko zamatye ajikelezileyo, imeko yelitye elijikelezileyo, ifom yesakhiwo esixhasayo kunye nobukhulu be

itonela icandelo. Ngokubanzi, ulwakhiwo lwemibhobho emincinci ehambele phambili lusekwe ecaleni komgca wecontour yokomba phakathi koluhlu lwe-120 degrees.

Ngaphantsi kweemeko eziqhelekileyo: ubude be-conduit encinci L = ukuphakama kwinqanaba eliphezulu + 2m. Ubukhulu becatheter encinci: 38-50mm.

Icandelo langaphambili le-conduit encinci lenziwe kwi-cone shape kunye nobude malunga ne-10cm, kunye ne-hoop yensimbi enobubanzi be-6 ~ 8mm idityaniswe ekupheleni komsila.

I-angle ye-extrapolation ilawulwa ngokubanzi kwi-10 degrees ukuya kwi-15 degrees. Uxinzelelo lwe-grouting lulawulwa malunga ne-2MP.

Iradiyasi yosasazo oluludaka luqheleke ukuba yi-0.5m. Isantya se-grouting silawulwa kwi-50-100L / MIN. Ubude obudlulayo bombhobho omncinci ngamnye ojikelezayo bulawulwa ngaphakathi kwe-1m.

5. Ukuvelisa:

1) Ngokuqhelekileyo, yenziwe ngemibhobho yensimbi edibeneyo okanye engenamthungo kunye nobubanzi be-38 ~ 50mm.
2) Yenza imilo yekhowuni malunga ne-10cm ubude kumphambili we-conduit encinci, kwaye udibanise ihupula yentsimbi enobubanzi obuyi-6 ~ 8mm ekupheleni komsila.

Akukho mingxunya evulekayo ngaphakathi kwe-100cm ukusuka ekupheleni, kwaye inxalenye eseleyo icwangciswe ngomngxuma ophuphumayo we-6mm ububanzi kwi-plum blossom shape ye-20 ~ 30cm.

6. Ufakelo:

Indlela yokukhokelela okanye ngokuthe ngqo inokusetyenziswa.
I-1) Imingxuma yokubhobhoza nge-drill yombane, ububanzi bomngxuma bukhulu kune-10-20mm yobubanzi bombhobho omncinci, kwaye ubunzulu bomngxuma buxhomekeke kubude bombhobho.
2) Ukuba kunzima ukufaka i-catheter, sebenzisa i-pneumatic drill nge-jacking function ukuze udibanise i-casing.
3) Sebenzisa isivuthelo ukuvuthela inkunkuma emngxunyeni.
I-4) Isiphelo se-catheter encinci sihlanganiswe ngentambo yekotoni, ukwenzela ukuba i-catheter encinci ifakwe ngokusondeleyo kwi-drilled hole, kwaye i-port engenanto ivaliwe ngentambo yekotoni.
5) Emva kokuba i-conduit encinci ifakwe, kufuneka ivalwe ngekhonkrithi efafaziweyo ngaphakathi koluhlu oluthile olujikelezileyo. Ubukhulu bokutshiza bulawulwa kwi-5-8cm.

7. Umfanekiso:
