VII. Urupapuro rwicyuma.
Larsen ibyuma byo kubaka ibirundo bifitanye isano no guhagarika amazi numutekano mugihe cyo kubaka. Nimwe mubikorwa bikomeye muriyi mushinga. Mugihe cyubwubatsi, hagomba kwitonderwa ibikurikira byubwubatsi:
. Mbere yo gutwara, ugomba kuba umenyereye imiterere yimiyoboro yubutaka nububiko hanyuma ugashyiraho witonze umurongo wo hagati wukuri wibirundo.
. Birashobora gukoreshwa gusa nyuma yo gusanwa no kuzuza ibisabwa. Ibikiri bitujuje ibyangombwa nyuma yo gusanwa birabujijwe.
(3) Mbere yo gutwara, amavuta arashobora gukoreshwa mugufunga ikirundo cyicyuma kugirango byoroherezwe gutwara no gukuraho ikirundo cyicyuma.
. Iyo gutandukana ari binini cyane ku buryo bidashobora guhindurwa nuburyo bwo gukurura, bigomba gukururwa no kongera gutwara.
(5) Menya neza ko ibirundo by'ibyuma bitarenze metero 2 z'uburebure nyuma yo gucukura, kandi urebe ko bishobora gufungwa neza; byumwihariko, impande enye zubugenzuzi neza zigomba gukoresha impande zicyuma. Niba nta birundo by'ibyuma nk'ibi, koresha amapine cyangwa imyenda ishaje kugirango wuzuze ingendo hamwe nizindi ngamba zabafasha kugirango ubifunge neza kugirango wirinde kumeneka n'umucanga bitera ubutaka.
. impande zombi z'umuyoboro ufunguye muri rusange, hafi 1.5m munsi yikirundo hejuru, hanyuma uzisudira hamwe nudukoni two gusudira amashanyarazi. Noneho, koresha icyuma kizengurutse (200 * 12mm) buri metero 5, kandi ukoreshe ingingo zidasanzwe zimuka kugirango ushyigikire ibirundo byibyuma kumpande zombi. Iyo ushyigikiwe, utubuto twimuka twimuka tugomba gukaza umurego kugirango harebwe niba uburebure bwikirundo cyibyuma bya Larsen hamwe nubucukuzi bwimyobo.
(7) Mugihe cyo gucukura umwobo fatizo, reba impinduka zurupapuro rwicyuma igihe icyo aricyo cyose. Niba haribintu bigaragara guhirika cyangwa kuzamurwa, hita wongera inkunga yingirakamaro kubice byatsinzwe cyangwa byazamuye.
Ⅷ. Gukuraho ibirundo by'ibyuma
Nyuma yo kuziba urufatiro rwuzuye, ibirundo by'ibyuma bigomba gukurwaho kugirango bikoreshwe. Mbere yo gukuraho ibirundo by'ibyuma, uburyo bwo gukuraho ikirundo, igihe cyo gukuraho ikirundo hamwe no gutunganya umwobo wubutaka bigomba kwigwa neza. Bitabaye ibyo, kubera kunyeganyega gukuraho ikirundo hamwe nubutaka bukabije butwarwa n’ibirundo, ubutaka buzarohama kandi buhinduke, ibyo bizangiza imiterere yubutaka bwubatswe kandi bigira ingaruka ku mutekano w’inyubako zumwimerere zegeranye, inyubako cyangwa imiyoboro yo munsi. Ni ngombwa cyane kugerageza kugabanya ubutaka butwarwa nibirundo. Kugeza ubu, ingamba nyamukuru zikoreshwa ni ugutera amazi no gutera umucanga.
(1) Uburyo bwo kuvoma ikirundo
Uyu mushinga urashobora gukoresha inyundo yinyeganyeza kugirango ukurure ibirundo: koresha kunyeganyega ku gahato byatewe ninyundo yinyeganyeza kugirango uhungabanye ubutaka kandi usenye ubumwe bwubutaka buzengurutse ibirundo byibyuma kugirango utsinde imbaraga zo gukuramo ikirundo, kandi wishingikirize ku kuzamura ibindi. imbaraga zo kubikuraho.
(2) Kwirinda mugihe ukurura ibirundo
a. Ahantu ho gutangirira no gukurikiranya ikirundo: Kubirindiro byicyuma gifunze urukuta, aho gutangirira gukuramo ibirundo bigomba kuba birenze 5 kure yikirundo. Intangiriro yo gukuramo ikirundo irashobora kugenwa ukurikije uko ibintu bimeze iyo ibirundo byarohamye, kandi uburyo bwo kuvoma bushobora gukoreshwa nibiba ngombwa. Itondekanya ryo gukuramo ikirundo nibyiza kuba bitandukanye no gutwara ikirundo.
b. Kunyeganyega no gukurura: Iyo ukuyemo ikirundo, urashobora kubanza gukoresha inyundo yinyeganyeza kugirango uhindure impera yumutwe wikirundo kugirango ugabanye ubutaka, hanyuma ubikuremo mugihe unyeganyega. Kurupapuro rwurupapuro rugoye gukuramo, urashobora kubanza gukoresha inyundo ya mazutu kugirango uhindure ikirundo munsi ya 100 ~ 300mm, hanyuma uhindurwe ukanyeganyega hanyuma ugikuremo inyundo yinyeganyeza.
(3) Niba ikirundo cy'icyuma kidashobora gukururwa, harashobora gufatwa ingamba zikurikira:
a. Koresha inyundo yinyeganyeza kugirango uyongere uyikubite kugirango utsinde imbaraga zatewe no gufatana nubutaka n'ingese hagati yo kurumwa;
b. Kuramo ibirundo muburyo butandukanye bwurupapuro rwikurikiranya rwo gutwara;
c. Ubutaka kuruhande rwurupapuro rwerekana umuvuduko wubutaka ni bwinshi. Gutwara urundi rupapuro ruringaniye hafi yarwo birashobora gutuma urupapuro rwumwimerere rusohoka neza;
d. Kora ibinono ku mpande zombi z'urupapuro hanyuma ushiremo bentonite kugirango ugabanye imbaraga mugihe ukuramo ikirundo.
(4) Ibibazo bisanzwe hamwe nuburyo bwo kuvura ibyuma byubaka ibirundo:
a. Kugoreka. Impamvu yiki kibazo nuko kurwanya hagati yikirundo bigenda no gufunga ikirundo byegeranye ni binini, mugihe kurwanya kwinjirira mu cyerekezo cyo gutwara ikirundo ari bito; uburyo bwo kuvura ni: koresha ibikoresho byo kugenzura, kugenzura no gukosora igihe icyo aricyo cyose mugihe cyubwubatsi; koresha umugozi winsinga kugirango ukurure umubiri wikirundo mugihe uhengamye, gukurura no gutwara icyarimwe, hanyuma ukosore buhoro buhoro; bika gutandukana bikwiye kurupapuro rwambere rutwaye.
b. Torsion. Impamvu yiki kibazo: gufunga ni ihuriro rifunze; uburyo bwo kuvura ni: gufunga imbere yurupapuro rwikariso hamwe namakarita mu cyerekezo cyo gutwara ikirundo; shyira uduce twa pulley mu cyuho ku mpande zombi hagati y'ibirundo by'ibyuma kugirango uhagarike kuzenguruka ikirundo cy'urupapuro mugihe cyo kurohama; kuzuza impande zombi zifunga bufunike yimpapuro ebyiri hamwe nudupapuro hamwe nigituba cyibiti.
c. Guhuza. Impamvu yikibazo: ikirundo cyurupapuro rwicyuma kiragoramye kandi cyunamye, byongera ubukana bwikibanza; uburyo bwo kuvura ni: gukosora igipande cyurupapuro mugihe; gutunganya by'agateganyo ibirundo byegeranye byayobowe no gusudira ibyuma.
9. Gutunganya ibyobo byubutaka mubirundo byibyuma
Ibirundo by'ikirundo bisigaye nyuma yo gukuramo ibirundo bigomba kuzuzwa mugihe. Uburyo bwo gusubira inyuma bukoresha uburyo bwo kuzuza, kandi ibikoresho bikoreshwa muburyo bwo kuzuza ni chipi yamabuye cyangwa umucanga wo hagati.
Ibyavuzwe haruguru nibisobanuro birambuye byintambwe zo kubaka ibirundo bya Larsen. Urashobora kubyohereza kubantu bakeneye hafi yawe, witondere Imashini za Juxiang, kandi "wige byinshi" buri munsi!
Yantai Juxiang Construction Machinery Co., Ltd. ni imwe mu masosiyete manini manini ashushanya imashini zikora ibicuruzwa mu Bushinwa. Imashini ya Juxiang ifite uburambe bwimyaka 16 mubikorwa byo gutwara ibinyabiziga, abashakashatsi barenga 50 n’abashakashatsi mu iterambere, kandi ikora ibikoresho birenga 2000 by’ibikoresho byo gutwara ibirundo buri mwaka. Ikomeza ubufatanye bwa hafi n’abakora imashini zo mu murongo wa mbere nka Sany, XCMG, na Liugong. Ibikoresho byo gutwara ibirundo bya Juxiang bikozwe neza, byateye imbere mu ikoranabuhanga, kandi byagurishijwe mu bihugu 18 ku isi, byahawe ishimwe bose. Juxiang ifite ubushobozi buhebuje bwo guha abakiriya ibikoresho bya sisitemu byuzuye kandi byuzuye nibisubizo, kandi ni serivisi yizewe itanga ibikoresho byubwubatsi.
Murakaza neza kugisha inama no gufatanya natwe niba hari ibyo ukeneye.
