3. ụkpụrụ nkwado:

1) The na-eduga obere conduit bụ nnọọ irè inyeaka usoro nkwụsi ike n'ihu gwupụtatụrụla.

N'ịwube nkume strata na-esighị ike na nke gbajiri agbaji, obere oghere dị elu na-ekere òkè n'ịgbasi ike

stratum nkume rụrụ arụ. Mgbe grouting gasịrị, a na-eme ka nkwụsi ike nke nkume ndị gbara ya gburugburu na-adịghị ike na-adịghị ike, nke bara uru

na nkwụsi ike nke nkume gbara ya gburugburu mgbe gwupụtara ya na njedebe nke oge nkwado mbụ. , nke mere na

A gaghị emebi nkume ndị gbara ya gburugburu ruo mgbe ọ dara.

2) The elu obere ọkpọkọ grouting kwesịrị ekwesị maka adịghị ike gbara ya gburugburu nkume nke ọwara arch, rụrụ, uncohesive ala oyi akwa,

ájá oyi akwa na ogbenye onwe-stabilizing ike na gravel (pebble) nkume larịị gbajiri nkume oyi akwa.
3) Ọnọdụ na nkwụsi ike nke nkume gbara ya gburugburu nwere ike gbanwee site na-agbapụta site na obere oghere dị elu.

Mgbe etinyere grouting n'ime ebe adịghị ike ma ọ bụ nke na-adịghị mma ma ọ bụ mgbaji nke mmiri na-agbaji agbaji gburugburu nkume;

ọ nwere ike na-akpachi anya na ike. Ọkpụkpọ ahụ na-anọchi anya mmiri na ikuku dị n'etiti irighiri ala na n'ime nkume

fissures site na njuputa, kewaa, wdg, wee nọrọ n'ọnọdụ ya. , Ahụ ahụ jikọtara ya na ike dị elu na ezigbo mgbochi mmiri

4. Oke:

Ekwesịrị ikpebi parampat maka owuwu nke obere oghere dị elu dị ka mpaghara ala

ọnọdụ nke nkume gbara ya gburugburu, ọnọdụ nke nkume gbara ya gburugburu, ọdịdị nke usoro nkwado na nha nke

ngalaba ọwara. N'ozuzu, a na-edobe ihe owuwu nke obere ọwa mmiri dị elu n'akụkụ ahịrị ngwupụta ihe n'ime oke ogo 120.

N'okpuru ọnọdụ nkịtị: ogologo nke obere conduit L = elu nke elu nzọụkwụ + 2m. Obere catheter dayameta: 38-50mm.

A na-eme akụkụ dị n'ihu nke obere conduit ka ọ bụrụ ọdịdị cone nke dị ihe dị ka 10cm n'ogologo, a na-ejikọtakwa ihe mkpuchi ígwè na dayameta nke 6 ~ 8mm na njedebe ọdụ.

A na-achịkwa akụkụ extrapolation na ogo 10 ruo ogo 15. A na-achịkwa nrụgide grouting na ihe dịka 2MP.

Oghere mgbasa ozi slurry bụ n'ozuzu 0.5m. A na-achịkwa ọsọ grouting na 50-100L/MIN. A na-achịkwa ogologo nkpuchi nke obere ọwa mmiri ọ bụla na-ekesa n'ime 1m.

5. Na-emepụta:

1) N'ozuzu, ọ na-mere nke welded ma ọ bụ enweghị nkebi ígwè ọkpọkọ na a dayameta nke 38 ~ 50mm.
2) Mee ka cone dị ihe dị ka 10cm n'ogologo n'ihu njedebe nke obere conduit, ma were eriri ígwè na dayameta nke 6 ~ 8mm na njedebe ọdụ.

Ọ dịghị oghere na-emeghe n'ime 100cm site n'azụ azụ, na akụkụ nke fọdụrụ ka a na-ahazi na dayameta nke 6mm na-ejupụta oghere n'ụdị piom okooko osisi nke 20 ~ 30cm.

6. Nwụnye:

Enwere ike iji ụzọ ntinye ma ọ bụ ntinye aka ozugbo.
1) Na-egwupụta oghere na ọkụ eletrik, dayameta nke oghere ahụ dị ukwuu karịa 10-20mm nke dayameta nke obere eriri, na omimi nke oghere na-adabere na ogologo nke eriri.
2) Ọ bụrụ na ọ siri ike ịtinye catheter, jiri pneumatic drill na jacking jack jack casing.
3) Jiri ihe na-afụ ụfụ na-ekpochapụ ihe ndị dị n'ime oghere.
4) A na-eji eriri owu kechie njedebe nke obere obere catheter, nke mere na obere catheter na-ejikọta ya na oghere a gbawara agbawa, ma jiri akwa owu mechie ọdụ ụgbọ mmiri ahụ efu.
5) Mgbe etinyere obere eriri mmiri ahụ, a ga-eji kọnkịta a na-efesa mechie ya n'ime ebe ụfọdụ gburugburu ya. A na-achịkwa oke ịgba mmiri na 5-8cm.
