Excavation uye mhando yayo

Excavation - a mhango inopfurwa padombo guru pashure kupikidura yakagadzirwa zvicherwa uye matombo.

Zvichienderana chinangwa, basa pamwe dombo akakamurwa mhando.

Description acho

Underground kuchera kunoratidzwa muna kuti muchinjikwa chikamu chawo chine namahwindo denderedzwa, pasinei pane mbune pemvura. Kuwedzera pevhu mabasa yaitwa run zvokuti pasi. The rakavhurika kupikidura ane pakachena loop muchinjikwa chikamu.

Kana nzira pevhu unoshanda, kunogona:

- kuchera uye ubanguranyika;

- kuchera uye guta;

- kuchera uye gadziriro;

- Threaded;

- mogeji;

- okuchenesa.

Excavation, zvichienderana rwendo, ndiko ubanguranyika uye kugadzirwa. Chokutanga rinoshandiswa nokuda ubanguranyika uye kutsvaka deposits itsva, wechipiri - nokuti pokumuka deposits kuitira dzokubvisa kubva subsoil zvicherwa. Maintenance basa rakamuka-kamuka kudura, kugadzirira uye kuchenesa.

Kundizivisa kupikidura akagadzirirwa kuvhura yangu uye rokudzidzisa kuwana chicherwa mari.

Kugadzirira basa kugadzirira kukura munda wangu, uye vari kucheneswa kwacho pesimbi zvicherwa vanosunungurwa.

Anoita dombo kunotema paumbwe kana kukura dzesango dzichava. Anotanga pamusoro dura, wechipiri - iri dongo padombo.

Excavation inogona kuwedzerwa uye inzwi iri pakutsvaga reshiyo pakati longitudinal chikamu uye muchinjikwa chikamu nzvimbo zvakaipa padombo. Rakatanga, mukuwedzera, pane chinjikira, vachida uye tote.

Open kupikidura rakakamurwa yacherwa, inoerera, matsime, congresses.

muchinjikwa chikamu

Muchinjikwa sectional Maumbirwo ari chinjikira nzira zvinoenderana paruware zvivako uye avo ezvinhu, mirayiridzo uye simba nedombo nevezera, urefu basa uye rutsigiro mamiriro.

Yokufeva muchinjikwa-sectional chimiro batanidza Pfungwa, iyo isina kurerekera kuvabereki, sezvo approximates kuti chimiro yepanyama chematenga.

Kana pasina lateral kumanikidzwa yokucheka mapuranga, rectangular muchinjikwa-sectional chimiro inoshandiswa. Panyaya iyi, kuti goho wakasimba matanda, mwero kana espagnolette fastening.

Trapezoidal chimiro unopikiana zvose kutwasuka uye lateral kuvafurira. Kubhururuka chakagadzirwa huni, Precast kongiri uye simbi.

Muchinjikwa chinogona kuva dzeraundi, yokufeva uye yokufeva chimiro.

Yokufeva chimiro yakashandiswa kongiri uye masonry kutara.

Yokufeva fastener rinoshandiswa kutwasuka uye lateral nevezera padombo. Muchiitiko chino, budiriro kunosimbiswa simbi Maberere.

Kana kumanikidzwa yakazara yakanakisisa wakanyatsokodzera dzeraundi muchinjikwa-sectional chimiro. Uglespusknye matsime hazvigoni wakaiswa zvachose. Elliptical muchinjikwa chikamu rinoshandiswa, kana mumwe kumanikidzwa zvikuru nedzimwe zvinoriumba.

Paivakwa tunnels, hydraulic zvivako, subways vaishandisa elliptical mharadzano pamwe chinjikira uye rusvingo akabatana. sectional chimiro kunobva chinangwa rinotarisirwa kupikidura, uyewo kubva migodhi ezvinhu. Kunyanya, chimiro Vector kunokanganisa kunonyanyisa kwechirwere kufurirwa zvinoriumba, vane zvinofambirana akabatana ari ellipse.
