The tsvina Hurongwa murege zvakanaka kushanda pasina kugadzwa manhole. Akagadzawo manholes kubatsira kuongorora mashandiro wegadziriro, kuti ayo rokuongorora, kugeza uye kuchenesa.
matsime vakadaro ndakagadza yose pomumbure nhau, ramifications ayo, anokotama panguva junctions maviri kana kupfuura mapaipi mitsetse, shanduko iri gradient uye dhayamita kuti pombi nzira yokubudisa. On chikamu yakarurama pamusoro manholes kuiswa zvichienderana zvinoshanda mitemo nemirayiro, uye kure mumwe kunoenderana dhayamita ari pombi nzira yokubudisa. Saka, kana nyere yaitwa dhayamita pamusoro 150-600 neMM, daro pakati matsime pedyo anofanira kuva metres dzinenge 50, kugadzwa pombi ane dhayamita pamusoro 125 neMM, kure izvi hazvifaniri kuva anopfuura 40 mamita.
Ita manholes maumbirwo dzakasiyana-siyana. In chimiro vanogona kuva trapezoidal, rectangular kana denderedzwa. All zvatinosiita dzeraundi matsime ari mapaipi, apo nyere akatarirwa kusvika 500 mm dhayamita, vane dhayamita pamusoro 1000 mm rwomumwoyo nzvimbo unobvumira pachena akaisa rimwe mushandi aite zvakakodzera kugadziriswa kana basa rokuchenesa.
Rectangular manholes ndokuisa zvidhinha. Vanofanira kuva zvinotevera kukura: kureba haidereri pane mita rimwe yakafara ari kuwanda 90 CM mativi kuitira kuvaka manholes rinoshandiswa rakaoma nevhu mhinduro mucherechedzo 100, muna nyoro nevhu - chiratidzo 150. In Kana apo yokuvira kumativi manholes. mwero kongiri zvigadzirwa hazvibviri kuti chinangwa zvikonzero, pakuvaka kwavo, shandisa unokosha twasu-zvidhina building, izvo zvinoita kuti zvakarurama kwete chete kuita masonry, asiwo kuderedza chekubuda mhinduro.
Kazhinji kana kutenga imwe nyika kure kwebudiriro Nzvimbo mapaipi mudziyo anofanira zvichengetedze. Muchiitiko chino, nokuti sangano kwayo kupfuura yakakodzera mapurasitiki manholes, zviri duku zvikuru uye nokuyera kugadzwa kwavo hazvirevi kukwezva nokusimudza michina. Panzvimbo yayo, zvichienderana nzvimbo sewerage gadziriro yakarongwa sezvaiitwa nechepakati guta tsvina hurongwa. matsime Sewerage vari kuiswa pa pomumbure matavi aro yeimwe, kuchinja yakatenuka uye dhayamita. Feature manhole mapurasitiki ndiyo kuvapo makomba unobva zvikwepa nzira yokubudisa, zvisati zviri kongiri, apo makomba kuti kupaza pachavo. Chimwe chakanakira iri rakakwana chisimbiso pamatsime iri mapaipi muvhu nokuda achipa uye chigadzirwa upenyu. Long hwose nokuda Qualitative zvechadenga zvinhu, izvo avo inokosha ehupfumi asingaiti richaora, usingatangi tibatsirwe hunyoro, runotsungirira tinzwe hasha ezvinhu nayo kukurukura munguva kushanda.
