Amagqabantshintshi ngeAnchor Hollow Steel Bars
Imivalo yentsimbi ye-anchor evulekileyo iveliswa kumacandelo anobude obuqhelekileyo be-2.0, 3.0 okanye 4.0 m. Ubungakanani obuqhelekileyo bangaphandle beentsimbi zensimbi ezingenanto ukusuka kwi-30.0 mm ukuya kwi-127.0 mm. Ukuba kuyimfuneko, imivalo yentsimbi engenanto iyaqhubeka kunye namantongomane okudibanisa. Iindidi ngeendidi zamasuntswana okwenziwa kwedini asetyenziswa ngokuxhomekeke kuhlobo lomhlaba okanye ubunzima bamatye. Intsimbi yentsimbi engenanto ingcono kunebhari eqinile enendawo efanayo ye-cross-sectional ngenxa yendlela yokuziphatha engcono yesakhiwo ngokubhekiselele kwi-buckling, i-circumference kunye nokugoba ukuqina. Isiphumo siphezulu kwi-buckling kunye nokuzinza kwe-flexural yexabiso elifanayo lentsimbi.

Usetyenziso lweSelf Drilling Anchor Rods
Kwiminyaka yakutshanje, ngokunyuka kwemfuno yenkxaso ye-geotechnical, izixhobo zokomba zihlaziywa rhoqo kwaye zaphuhliswa. Kwangaxeshanye, iindleko zomsebenzi kunye nerenti ziye zanda, kwaye iimfuno zexesha lokwakha ziye zanda kakhulu. Ukongeza, ukusetyenziswa kweentonga ze-ankile ezizimbayo ngokwazo kwiimeko zejoloji ethanda ukudilika kuneziphumo ezibalaseleyo zokubambelela. Ezi zizathu zikhokelele ekwandeni kokusetyenziswa kweentonga ze-ankile ezizimbayo. Iintonga ze-ankile ezizibhobhozayo zisetyenziswa ikakhulu kwezi meko zilandelayo:
1. Isetyenziswa njenge-ankile intonga egxininisiweyo: isetyenziswa kwiimeko ezifana namathambeka, ukugrumba ngaphantsi komhlaba, kunye ne-anti-anti-floating ukubuyisela iintambo ze-ankile. I-self-drilling hollow rods ye-ankile igrunjwa ukuya kubunzulu obufunekayo, kwaye emva koko isiphelo se-grouting siyenziwa. Emva kokuqiniswa, uxinzelelo lusetyenziswa;
2. Isetyenziswe njenge-micropiles: I-self-drilling i-anchor rods evulekileyo inokugrunjwa kwaye ihlulwe phantsi ukuze yenze i-micropiles, esetyenziswa ngokuqhelekileyo kwiziseko zeenqaba zomoya, iziseko zothutho, iziseko zesakhiwo, ukugcina iziseko zeemfumba zodonga, iziseko zeemfumba zebhulorho, njl.
3. Isetyenziselwa izikhonkwane zomhlaba: ngokuqhelekileyo isetyenziselwa inkxaso ye-slope, ukutshintshwa kweentsimbi eziqhelekileyo zentsimbi ye-anchor, kwaye ingasetyenziselwa isiseko esinzulu senkxaso ye-slope slope;
4. Isetyenziselwa izikhonkwane zamatye: Kwamanye amathambeka okanye iitonela ezinemozulu embi kakhulu yomphezulu okanye uphuhliso oludityanisiweyo, iirodi ze-ankile ezizigrumba ngokwazo zingasetyenziselwa ukugrumba kunye nokugrutha ukudibanisa iibhloko zamatye kunye ukuphucula ukuzinza kwazo. Umzekelo, amathambeka amatye koohola bendlela kunye noololiwe abadla ngokudilika banokuqiniswa, kwaye iishedi zemibhobho eqhelekileyo nazo zinokutshintshwa ukuze ziqiniswe kwindawo evulekileyo yetonela;
5. Ukomelezwa okusisiseko okanye ulawulo lweentlekele. Njengoko ixesha lenkxaso yenkqubo yenkxaso ye-geotechnical yasekuqaleni isanda, ezi zakhiwo zenkxaso zinokuhlangabezana neengxaki ezithile ezifuna ukuqinisa okanye unyango, ezifana nokuguqulwa kwe-slope yasekuqaleni, ukulungiswa kwesiseko sokuqala, kunye nokuphakanyiswa kwendawo yendlela. Iirodi ze-ankile ezizigrumbayo ngokwazo zingasetyenziselwa ukugrumba kwithambeka lokuqala, isiseko, okanye kumhlaba wendlela, njl.njl., ukwenza igrouting kunye nokudibanisa iintanda, ukuthintela ukwenzeka kweentlekele zejoloji.
