Incamake ya Anchor Hollow Icyuma
Anchor Hollow Icyuma Byakozwe Mubice hamwe nuburebure busanzwe bwa 2.0, 3.0 cyangwa 4.0 m. Diameter ya diameter yicyuma cyijimye iva muri 30.0 mm kugeza 127.0 mm. Niba bibaye ngombwa, utubari twinshi dukomeje hamwe nutuntu duhuza. Ubwoko butandukanye bwibitambo bikoreshwa bitewe nubwoko bwubutaka cyangwa ubwinshi. Icyuma cya Hollow kiruta akabariye hamwe nigice kimwe-igice kimwe kubera imyitwarire myiza muburyo bwo kwishyurwa, kuzenguruka no kunanuka. Igisubizo ni ugukora neza kandi bituje kuri stal kimwe.

Ibisabwa byo kwigunga inkweto za anchor
Mu myaka yashize, hamwe no gukenera amafaranga ya geotechnical, ibikoresho byo gucukura byaragangishwa kandi bigatera imbere. Muri icyo gihe, ibiciro byo gukodeshwa no gukodesha byiyongereye, kandi ibisabwa mu gihe cyo kubaka byarushijeho kuba hejuru. Mubyongeyeho, gukoresha kwinezeza gusa inkoni ya ancy mumiterere ya geologiya ikunze gusenyuka ifite ingaruka nziza zo kubura. Izi nyiga zatumye habaho ikoreshwa ryinshi ryo kwigurika inkoni ya ankeri. Kwinjiza inkweto za ankeri ya ankeri zikoreshwa cyane muri ibi bikurikira:
1. Yakoreshejwe nk'inkoni yakubise inanga: ikoreshwa mu buryo bumwe nk'ubwoya, ubucukuzi bw'ubutaka, no kurwanya uburebure bwo gusimbuza insinga. Kwicuza imiyoboro ya anker yuzuye iracukurwa mubintu bisabwa, hanyuma birangira ko bikara. Nyuma yo gukomera, gutorwa bikorwa;
2. Ikoreshwa nka miciri: kwigunga inkoni ya ankeri ya ankeri irashobora gucogora kandi igatangwa nurufatiro rwibihingwa, urufatiro rwubaka, ibirango byikiraro, nibindi;
3. Ikoreshwa mu misumari y'ubutaka: Bikunze gukoreshwa mu nkunga, gusimbuza amande asanzwe y'icyuma, kandi birashobora kandi gukoreshwa mu nkunga y'imisozi miremire ihanamye;
4. Ikoreshwa mumisumari ya rock: Muburyo bumwe bwurutare cyangwa amabuye yubutaka bukabije cyangwa iterambere ryinshi, kwigurika inkoni ya anker, kwigunga inkoni zo gucukura no kwinezeza kugirango uhagarike urutare hamwe kugirango bakureho neza. Kurugero, imisozi minini yimihanda hamwe na gari ya moshi ikunda gusenyuka irashobora gushimangirwa, kandi ibisimba bisanzwe nabyo birashobora kandi gusimburwa na shepe isanzwe birashobora gusimburwa no gushimangira kumurongo wa tunneli;
5. Gushimangira imbaraga cyangwa gucunga ibiza. Nkigihe cyo gushyigikira sisitemu yumwimerere yubufasha bwiyongera, izi nyubako zifasha zishobora guhura nibibazo bimwe na bimwe bisabwa cyangwa kuvura, nko gucuruza ahantu h'umwimerere, no kuzamurwa hejuru yumuhanda. Kwiyoroshya kwinezeza inkoni zuzuye zirashobora gukoreshwa muguhindura ahantu h'umwimerere, umusingi, cyangwa inzira nyabagendwa, nibindi, gushimangira ibitagenda neza.
