Intangiriro y'ibicuruzwa

Kumenyekanisha ibirundo byacu byo mu rwego rwo hejuru kubikorwa byubwubatsi, byateguwe kugirango byumvizwe ibyangombwa bifatika byubwubatsi bugezweho. Yakozwe mu ruganda rwacu rw'ubuhanzi muri CONGZHOU, Intara ya Hebei, ibirundo byacu by'icyuma bikozwe hakoreshejwe ibikoresho byiza n'ikoranabuhanga ryiza. Kuva twabishika mu 1993, twakoze kuba indashyikirwa kandi tuba umuyobozi winganda, utwikiriye akarere ka metero kare 350.000 n'umutungo wose w'intama miliyoni 680.

Ibirundo byacu by'icyuma byateguwe kugirango twiringirwe kandi biraramba, biba byiza kubwibyo bisabwe byubatswe nka cofferdams. Buri kirundo kirimo inzira nziza yo kugenzura ubuziranenge kugirango ikemure ishyingira amahame yo hejuru, akaguha amahoro kumishinga yawe yo kubaka. Hamwe nabakozi ba 680 b'abahanga, turashobora gukoresha imishinga y'ubunini ubwo aribwo bwose, tutanga ibicuruzwa bitahuye gusa nibyo twiteze, ahubwo birarenga.

Waba ukora kumushinga munini wa remezo cyangwa umushinga muto wubwubatsi, ibirundo byacu byo hejuru byicyuma nibisubizo byuzuye kubyo ukeneye. Wizere imyaka yacu yuburambe nubwitange ku bwiza kuguha ibikoresho byiza kumishinga yawe yo kubaka. Hitamo ibyacuibyumaKu mbaraga zabo, kwizerwa no gukora, no guhura nitandukaniro ibikoresho byiza bishobora gukora mumushinga wawe wubaka.

Inyungu y'ibicuruzwa

1. Bizwi cyane kubwizerwa nimbaraga zabo, ibirundo by'icyuma nibyiza kubintu bitandukanye byubaka, nka cofferdams.

2. Igishushanyo mbonera cyibikoresho byemeza umutekano n'umutekano bisabwa ku rufatiro n'ibindi bikorwa remezo bikora.

3. Icyuma cyiza cyakoreshejwe mugukora ibirundo by'icyuma bibatwara imitwaro nini no kurwanya ibintu bitesha agaciro nk'ikongoro no kugenda kw'ubutaka.

4. Ibikorwa byo gutunganya byakoreshejwe namasosiyete nkayacu, iherereye i Cantgzhou, Intara ya Hebei, menya neza ko buri kirundo giterana ubuziranenge bukomeye, guha abashoramari amahoro yo mumutima.

Ibicuruzwa Kubura

1. Kimwe mu bibazo by'ingenzi biratwara; Icyuma cyiza kihenze, gishobora gutera ingengo yimishinga yo kwiyongera.

2. Igikorwa cyo kwishyiriraho kirashobora kuba ingorabahizi, bisaba ibikoresho byihariye nubuhanga bifite ubuhanga, bishobora kwagura igihe cyumushinga.

3. Mugihe ibirundo by'icyuma biramba, birashobora kwibasirwa nubwoko bumwe bwibigwari niba bitakozwe neza cyangwa bibungabungwa neza.

Gusaba

Mu isi yahindutse isi yose yo kubaka, guhitamo ibikoresho bigira ingaruka zikomeye ku ntsinzi no kuramba umushinga. Ibikoresho bimwe byagaragaye ko bitavugwa ni ibinyampeke byiza. Ibi bikinisho by'ibyuma bikozwe neza kandi ni ngombwa mubyo dusaba bitandukanye, cyane cyane mugushiraho urufatiro rukomeye no kubungabunga ubunyangamugayo bwubaka.

Byakozwe ukoresheje ibikoresho byiza nikoranabuhanga ryiza,umuyoboro w'icyumaIbirundo ni amahitamo yizewe kumushinga uwo ariwo wose wo kubaka. Igishushanyo mbonera cyabo gikomeye ningirakamaro cyane mubisabwa nka cofferdams, aho haruhuka n'umutekano ari ngombwa. Ibi birundo birashobora kwihanganira imitwaro iremereye kandi ikaze ibidukikije, ikabatuma bahitamo injeniyeri n'abashoramari.

Mu gusoza, ukoresheje ibirundo byiza byicyuma birakenewe kugirango umushinga wubwubatsi. Kwizerwa kwabo, imbaraga zabo, hamwe nibikorwa byo gutunganya byateye imbere bituma baba byiza kubishingiro nibikorwa remezo. Mugihe dukomeje guhanga udushya no kunoza ibicuruzwa byacu, tuguma twiyemeje gushyigikira inganda zubwubatsi nibikoresho byiza. Hitamo ikirundo cyacu cyicyuma cyumushinga wawe utaha ukagira itandukaniro muburyo bwiza nibikorwa.

Ibibazo

Q1: Amashanyarazi y'ibyuma ni iki?

Ibirundo by'icyuma ni imiterere ya silindical ikozwe mubyuma birebire, byateguwe gutwarwa cyane mu butaka kugira ngo batange inkunga ya Foundation. Bakozwe bakoresheje ikoranabuhanga bambere kugirango bakemure ko bujuje ibyangombwa bifatika byimishinga itandukanye yo kubaka.

Q2: Kuki uhitemo ibirundo by'icyuma byo kubaka?

Ibirundo by'icyuma bizwiho imbaraga zabo no kuramba. Igishushanyo mbonera cyukuri kituma biba byiza kuri Cofferdams aho hazahantu ari ngombwa cyane. Ibi birundo birashobora kwihanganira imitwaro iremereye kandi ikaze ibidukikije, bikaguma amahitamo yizewe ku rufatiro n'ibindi bikorwa by'ibikorwa remezo.

Q3: Isosiyete yawe irihe?

Isosiyete yacu yashinzwe mu 1993 kandi iherereye mu mujyi wa Congzhou, Intara ya Hebei. Irimo ubuso bwa metero kare 350.000, ifite imitungo yose ya miliyoni 680 Yuan, kandi kuri ubu ifite abakozi 680. Twiyemeje gutanga ibinyampeke birebire byijimye byujuje ibyo bakeneye byabakiriya.

Q4: Ni izihe ngamba zizeza ubuziranenge urimo?

Twibanze ku mico kuri buri cyiciro cyumusaruro. Ibirundo byacu by'icyuma byakorewe gukoresha ibikoresho byiza kandi bigakoresha ikoranabuhanga ryiza kugirango tumenye kwizerwa. Gahunda yacu yo kugenzura ubuziranenge iremeza ko ibicuruzwa byacu byujuje ubuziranenge hamwe nibisobanuro byabakiriya.

Mbere: Imiyoboro ya Verisile ibyuma yo gukoresha inganda

Ibikurikira: Umuyoboro wizewe wumusare kugirango uhuze umutekano wawe ukeneye
