Introduction to construction method of non-grooving pipeline

ʻO ka hana non-grooving e pili ana i ke ʻano hana o ka hoʻomoe ʻana a i ʻole ka ninini ʻana i nā paipu (drains) i loko o nā lua i ʻeli ʻia ma lalo o ka lepo ma ka ʻaoʻao.paipu.Aia nā ʻano paipu jacking, shield tunneling method, shallow bury method, directional drilling method, ramming pipe method, etc.

(1) Paʻa paipu jacking:

Pōmaikaʻi: kiʻekiʻe kūkulu pololei.Nā hemahema: ke kumu kūʻai kiʻekiʻe.

Ka laula o ka noi: lako wai a me nā paipu hoʻoheheʻe wai, nā pipeline i hoʻohui ʻia: nā pipeline pili.

Pili paipu anawaena: 300-4000m.Ka pololei o ke kukulu ana: emi mai±50mm.Ka mamao kūkulu: lōʻihi.

Ke kālaihonua kūpono: nā papa lepo like ʻole.

(2) Ke ala pale

Pōmaikaʻi: ka wikiwiki o ke kūkulu ʻana.Nā hemahema: ke kumu kūʻai kiʻekiʻe.

Ka nui o ka noi: ka wai a me nā paipu wai, nā pipeline i hoʻohui ʻia.

Pili paipu anawaena: ma luna o 3000m.ʻO ka pololei o ke kūkulu ʻana: hiki ʻole ke kāohi.Ka mamao kūkulu: lōʻihi.

Ke kālaihonua kūpono: nā papa lepo like ʻole.

(3) Paʻu ʻia i kanu ʻia ka paipu (tunnel) alanui

Pōmaikaʻi: hoʻohana ikaika.Nā pōʻino: lohi ka wikiwiki o ke kūkulu ʻana a me ke kumukūʻai kiʻekiʻe.

Ka nui o ka noi: ka wai a me nā paipu wai, nā pipeline i hoʻohui ʻia.

Pili ke anawaena paipu: ma luna o 1000mm.Ka pololei o ke kūkulu ʻana: emi iho a i ʻole like me 30mm.Ka mamao kūkulu: lōʻihi.

Ke kālaihonua pili: nā ʻano hana like ʻole.

(4) Ka wili kuhikuhi

Pōmaikaʻi: ka wikiwiki o ke kūkulu ʻana.Nā hemahema: haʻahaʻa hoʻomalu pololei.

Ka laulā o ka noi: nā paipu hikiwawe.

Pili paipu anawaena: 300mm1000mm.ʻO ka pololei o ke kūkulu ʻana: ʻaʻole ʻoi aku ma mua o 0.5 mau manawa o ke anawaena o loko.Ka lōʻihi o ke kūkulu ʻana: ʻoi aku ka pōkole.

Pili honua: ʻAʻole pili i ke one, ka ʻiliʻili, a me nā ʻāpana wai.

(5) ʻO ke ʻano o ka paipu paʻa

Pōmaikaʻi: ka wikiwiki o ke kūkulu ʻana a me ke kumu kūʻai haʻahaʻa.Nā hemahema: haʻahaʻa hoʻomalu pololei.

Ka nui o ka noi: paipu kila.

Pili paipu anawaena: 200mm1800mm.ʻO ka pololei o ke kūkulu ʻana: hiki ʻole ke kāohi.Ka mamao kūkulu: pōkole.

ʻO ke kālaihonua pili: ʻaʻole kūpono ka stratum lawe wai, paʻakikī ke one a me ka ʻiliʻili.
