I.Kusuma kwete-dig tekinoroji
No-dig tekinoroji imhando yekuvaka tekinoroji yekuisa, kugadzirisa, kutsiva kana kuona mapaipi epasi pevhu uye tambo nenzira yekuchera kushoma kana kusachera.Kuvaka kwete-kuchera kunoshandisa musimboti wekudhirowa tekinoroji, inoderedza zvakanyanya rudo rwepasi pevhu kuvaka pombi kune traffic, nharaunda, zvivakwa uye kugara nekushanda kwevagari, inova chikamu chakakosha muguta razvino rekuvaka kwehunyanzvi uye manejimendi.
Kuvaka kusina trenchless kwakatangwa kubva kuma1890 uye kwakakura ndokuva indasitiri muma1980 munyika dzakabudirira.Yanga ichikura nekukurumidza mumakore makumi maviri apfuura, uye parizvino yakashandiswa zvakanyanya mumapurojekiti mazhinji ekuisa pombi uye kugadzirisa mapurojekiti mumaindasitiri mazhinji akadai sepeturu, gasi rechisikigo, kupihwa kwemvura, magetsi, kufambiswa kwenhare uye kupisa.
II.Kushanda Nheyo uye Matanho ekuvakwa kweHorizontal Directional Drill
1.Kusvetwa kwechibooreso uye chibooreso tsvimbo
Mushure mekugadzirisa muchina, zvinoenderana nekona yakatarwa, chibooreso chinotyaira chidhiraivho chichitenderera uye kumberi nesimba remusoro wesimba, uye kukanda zvinoenderana nekudzika kunodiwa uye kureba kweprojekiti, kuyambuka zvipingamupinyi wouya pasi. pamusoro, pasi pekutonga kwenzvimbo.Panguva yekusunda, kuitira kudzivirira chibooreso chisarovera nekuvhara nevhu revhu, chinofanira kuita kuzvimba simende kana bentonite nepombi yedhaka kuburikidza nechibooreso nechidhiraivho, uye nguva yekuomesa nzira uye kudzivirira gomba kubva. caving in.
2.Reaming pamwe remer
Mushure mekunge chibooreso chinotungamira chidhiro kubva pasi pevhu, bvisa chibooreso uye batanidza reamer kune chiboorero chidhiri wochigadzirisa, dhonza kumashure musoro wesimba, chibooreso chinotungamira chinodzosera kumashure, uye kuwedzera saizi ye gomba.Maererano nenyere dhayamita uye siyana, kuchinja siyana saizi reamer uye ream kamwe kana kupfuura nguva kusvikira asvika zvinodiwa gomba dhayamita.
3.Dhonza pombi
Kana wasvika paburi rinodiwa dhayamita uye mutsigiri wozodzoserwa kumashure kekupedzisira, gadzirisa pombi kune reamer, musoro wesimba unodhonza chibooreso uye unounza reamer nepombi kuti zvidzokere kumashure, kusvika pombi yadhonzwa. kunze kusvika pasi, pombi yekuisa mabasa inopedzwa.
