Advance ductule, Pipe Shed, grout pombi yekuchera mugero
1. Tsanangudzo iri nyore:
Iyo yepamusoro diki conduit inzira yemaitiro mukuita kwekuchera tunnel. Inonyanya kushandiswa munzvimbo isina simba yakaputsika
nenguva pfupi yekudzikamisa, iyo isina kudzika yakavigwa chikamu, chikamu chekumanikidza chikamu pamusuwo, chikamu chejecha,
chikamu chejecha nematombo, nzvimbo yakaputsika uye zvimwe zvikamu. pre-rutsigiro.
2. Giredhi:
Q195, Q235, SS400, S235, STK400
3. Support principle:
1) Iyo inotungamira diki conduit inonyatso inoshanda yekubatsira yekuvaka nzira yekudzikamisa kumeso kwekuchera.
Mukuvaka kweiyo isina simba uye yakaputsika dombo strata, iyo yepamusoro diki conduit inoita basa mukusimbisa iyo
loose rock stratum. Mushure mekugadzira, kugadzikana kwedombo rakasununguka uye risina simba rakapoteredza rinowedzerwa, iro rinobatsira
kune kugadzikana kwedombo rakapoteredza mushure mekuchera uye kupera kwekutanga kwekutsigira nguva. ,kuitira kuti
dombo rakapoteredza harizogadziriswi uye kukuvadzwa kusvikira raputsika.
2) Iyo yepamberi diki pombi grouting inokodzera iyo isina kusimba yakatenderedza dombo remugero arch, yakasununguka, isina kubatana ivhu layer,
jecha rukanda rusina kugona kuzvidzikamisa nerukangarabwe (hurungudo) mwero wedombo wakaputsika dombo.
3) Mamiriro uye kugadzikana kwedombo rakapoteredzwa rinogona kuchinjwa ne grouting kuburikidza nepamusoro pediki conduit.
Mushure mekunge grouting yaiswa mune isina kusimba kana yakasununguka kuumbwa kana kuputsika kwedombo rinotakura mvura rakaputsika rakatenderedza dombo,
inogona kunge iri pedyo nekusangana nekusimbisa. Iyo slurry inotsiva mwando nemhepo pakati pezvimedu zvevhu uye mudombo
fissures nekuzadza, kupatsanura, nezvimwewo, uye obva atora chinzvimbo chayo. , Muviri wakabatanidzwa une simba rakakwirira uye yakanaka isina mvura
kuita kunonatsiridza zvakanyanya yakasununguka uye yakatyoka yakatenderedza dombo. .
4. Parameter:
Izvo zviyero zvekuvakwa kweiyo yepamusoro diki conduit inofanirwa kutariswa zvinoenderana nemuganhu we geological
mamiriro edombo rakapoteredza, mamiriro edombo rakapoteredza, chimiro chechimiro chekutsigira uye ukuru hwe
mugero chikamu. Kazhinji, kuvakwa kwemakorokoto madiki epamberi anoiswa padivi pemutsetse wekuchera contour mukati mehuwandu hwe120 madhigirii.
Mumamiriro ezvinhu akajairika: kureba kwegomba duku L = kureba kwenhanho yepamusoro + 2m. Diki catheter dhayamita: 38-50mm.
Chikamu chemberi chemukoto muduku chinogadzirwa kuva chimiro chekoni nehurefu hunenge 10cm, uye hovha yesimbi ine dhayamita ye6 ~ 8mm inosungirirwa pamuswe.
The extrapolation angle inowanzodzorwa pa10 degrees kusvika 15 degrees. Iyo grouting pressure inodzorwa inosvika 2MP.
Iyo slurry diffusion radius inowanzoita 0.5m. Iyo grouting kumhanya inodzorwa pa50-100L/MIN. Kureba kunopindirana kwega yega inotenderera diki conduit inodzorwa mukati me1m.
5. Kugadzira:
1) Kazhinji, inogadzirwa ne welded kana isina musono pombi dzesimbi dzine dhayamita ye38 ~ 50mm.
2) Ita chimiro chekoni chingaita 10cm kureba kumberi kwegeji diki, uye weld hoop yesimbi ine dhayamita ye6 ~ 8mm kumucheto wemuswe.
Hapana maburi anovhurwa mukati me100cm kubva kumucheto kumashure, uye chikamu chasara chakarongwa ne 6mm dhayamita yekufashukira mugomba mupramu maruva chimiro che20 ~ 30cm.
6. Kuiswa:
Kutungamira-kuburikidza kana kunanga kusunda-mu nzira inogona kushandiswa.
1) Dhonza maburi ane drill yemagetsi, dhayamita yegomba yakakura kudarika 10-20mm yehupamhi hwegomba duku, uye kudzika kwegomba kunoenderana nehurefu hwegomba.
2) Kana zvakaoma kupinza catheter, shandisa pneumatic drill ine jacking basa kuti ubate casing.
3) Shandisa blower kuburitsa marara mugomba.
4) Mhedziso yekatheti duku yakaputirwa nemucheka wekotoni, kuitira kuti kateti duku inyatsobatanidzwa kune gomba rakacherwa, uye gomba risina chinhu rakavharwa nemucheka wekotoni.
5) Mushure mekunge iyo diki yaiswa, inofanirwa kuvharwa nekongiri yakapfapfaidzwa mukati meimwe nharaunda yakaitenderedza. Ukobvu hwekupfapfaidza hunodzorwa pa5-8cm.
7. Mufananidzo:
