Mhedziso yeT76 Yakazara Threaded Steel Self Drilling Rock Bolt
Self drilling anchors imhando yakakosha yetsvimbo anchors. Self-drilling anchor ine chibairo chibooreso, mhango simbi simbi yeakakodzera kunze uye mukati dhayamita uye coupling nzungu. Mutumbi weanchor wakagadzirwa nechubhu yesimbi isina mhango ine shinda yekunze yakatenderera. Simbi chubhu ine chibooreso chekupira kumucheto uye nati inoenderana nesimbi yekupedzisira ndiro. Kuzvibooresa anchors anoshandiswa nenzira yekuti hollow simbi bar (tsvimbo) ine inoenderana chibayiro dhiri pamusoro payo pachinzvimbo chekare chibooreso.

Iko mukana uye kushandiswa kweSelf Drilling Anchor Rods
Basa re hollow grouting spiral anchor rod is grouting, saka inonziwo grouting pombi. Inogona kutenderedzwa mukuronga kwese kuti iwane kudzvanywa kwekutanga. Pasi pekumanikidzwa, slurry yemukati inoyerera kunze, iyo isina kungoita yakagadziriswa pachayo, asiwo inopinda mugomba reanchor apo slurry inoputika, ichiita basa mukusimbisa dombo rakapoteredza. Iyo ine zvayakanakira mukushandisa uye kuronga, saka inogona kuratidza yayo mabhenefiti mukushandisa:
1, Izvo chaizvo pasi peichi chiitiko kuti yekutanga kukurumidza kutsigira mhedzisiro inogona kuwanikwa uye deformation yedombo rakatenderedza inogona kudzorwa zvakanaka kuti yakanaka kugadzikana mhedzisiro inogona kuwanikwa.
2, Inoshandisa nzira isina kujeka mukuronga, kubatanidza tsvimbo dzeanchor uye pombi dzekugadzira. Ndizvo chaizvo rudzi urwu rwekuronga kune zvakanakira zvikuru. Kana iri pombi yechinyakare, inogona kukonzera kurasikirwa nekuda kwekudhonza kumashure-uye-kunze, izvo zvisingazoratidze chiitiko chakadaro.
3, Inogona kuvandudza zvakanyanya kunaka kwepurojekiti, izvo chaizvo nekuti inokwanisa kuwana huwandu hwakakura hwekuzara panguva yekugadzira, uye pamwe chete negrouting, inogona kuzadzisa mhedzisiro yekumanikidza grouting.
4, kusarerekera kwayo kwakanaka. Nekuwedzera kwezvimwe zvishongedzo panguva yekushandiswa, inowedzera kusarerekera kwayo, ichibvumira iyo slurry kuputira iyo isina hollow anchor tsvimbo. Ndizvo chaizvo nekuda kweizvi kuti ngura haizooneki panguva yekushandiswa uye inogona kuwana zvechokwadi kushandiswa kwenguva refu.
5, Iyo zvakare yakanakira kwazvo pane mudziyo, iyo yakakoshawo zvakanyanya. Chero bedzi iri nyore pane mudziyo, inogona kupfupisa debugging uye nguva yekuvaka. Pamwe chete nemudziyo, hapasisina screws inodiwa kuti isangane nezvinodiwa zvechigadzirwa nut uye pad.
