Agasanduku k'ibyuma, byitwa kandi agasanduku k'icyuma, ni uburyo busanzwe bukoreshwa muburyo bw'ikiraro kirekire. Mubisanzwe bikoreshwa kubiraro binini-binini, byitwa agasanduku k'icyuma kuko gasa nagasanduku.Bishobora kugabanywamo ubwoko butatu: ikiraro kimwe cyogusanduku, ikiraro cyikubitiro kabiri, hamwe nikiraro kinini.
Mu kiraro kinini-gishyigikiwe n’ibiraro, agasanduku k'icyuma gakomeye kangana na metero magana cyangwa metero ibihumbi.
Igabanyijemo ibice byinshi byo gukora no kuyishyiraho, kandi igice cyayo cyambukiranya gifite ibiranga imiterere yagutse kandi iringaniye, kandi igipimo cyerekezo kigera kuri 1:10. Agasanduku k'icyuma gashirwaho muburyo bwo gusudira byuzuye isahani yo hejuru, isahani yo hepfo, urubuga, hamwe na transvers ibice, ibice birebire hamwe na stiffeners. Isahani yo hejuru ni ikiraro cya orthotropic ikiraro kigizwe nicyapa gitwikiriye hamwe na stiffituders ndende. Ubunini bwa buri sahani yububiko busanzwe bwicyuma bushobora kuba: gupfuka uburebure bwa 14mm, uburebure bwa U-burebure bwurubavu 6mm, ubugari bw umunwa wo hejuru 320mm, umunwa wo hasi wubugari 170mm, uburebure bwa 260mm, intera 620mm; uburebure bwa plaque yo hepfo 10mm, uburebure bwa U-bukomeye; Ubunini bwurubuga ruhengamye ni 14mm, ubunini bwurubuga rwagati ni 9mm; intera y'ibice bihinduranya ni 4.0m, n'ubugari ni 12mm; uburebure bw'igiti ni 2 ~ 3.5m.
Agasanduku k'icyuma ni uburyo bwubatswe bukoreshwa mubuhanga. Kugirango twige ingaruka zintera ya diaphragms ihindagurika ku kugoreka icyuma gishyigikiwe nicyuma gishyizwe munsi yumutwaro wibanze, icyuma gishyigikira icyuma cyoroshye hamwe numubare utandukanye wa diafragma ya transvers cyashyizweho kugirango kigereranye ingaruka zacyo zo kugoreka n'ingaruka zikomeye za torsion munsi yumutwaro, impinduka yo kugabanuka yingaruka nini yo kugoreka hamwe numubare wa diaphragms irabonetse. Umutwaro wibanze ushyirwa hejuru yisanduku ya girder y'urubuga, kandi byemewe ukurikije uburyo bune bwakazi bwo kugoreka, kugoreka gukomeye, kugoreka guhuza hamwe nuburemere bwa eccentric. Uburyo bwo kubora imitwaro irabaze.
Zhenjiang Great Wall Heavy inganda zifite toni zirenga 50 za crane, igishushanyo mbonera cyumwuga, gusudira, hamwe nitsinda rishinzwe gukora gukora no gushiraho ibiti bitandukanye byamasanduku.
Bitewe nuburyo bwubatswe, agasanduku k'icyuma gakoreshwa muri rusange gakoreshwa mu kuzamura amakomine ya komini; igihe cyubwubatsi bwumuhanda umuteguro muremure-wagumye ikiraro, ikiraro gihagarikwa, ikiraro cyubatswe gikomeretsa nicyuma cyabanyamaguru ikiraro cyicyuma.
