Umgodi oNye/uMngxuma omninzi wokuTya iSithi seSithi saMandla aphezulu

Umgodi oNye/uMngxuma omninzi oPhezulu-Amandla eStrand yokutshixa iStrand

Ii-ankile zeentambo zemigodi zibhekiselele kwii-ankile ezifakwe kwindawo evulekileyo yentambo ye-ankile (intambo yentsimbi) kwiitonela zemigodi yamalahle kwaye zinokucinezelwa. Emva koxinzelelo kunye noxinzelelo lwangaphambili, amandla okuqina entambo ye-anchor anokudluliselwa kwindawo exhasayo. , idlala indima yokugcina itonela lokuhamba. Idlala indima enkulu kwiiprojekthi zolwakhiwo olucinezelekileyo olunje ngemigodi, itonela, kunye neebhulorho. Ukuhlelwa kwenkqubo eqhelekileyo yeeankile:

(1) I-ankile esetyhula. Olu hlobo lwe-ankile luneempawu ezilungileyo zokuzibamba. I-tensioning ngokuqhelekileyo isebenzisa ii-jack-core jacks.

(2) Iiankile ecaba. Iiankile ezicaba zisetyenziswa ikakhulu kwi-prestressing enqamlezileyo yeedekhi zebhulorho, ii-slabs ezihollow, kunye ne-low-height girders zebhokisi ukwenza usasazo loxinzelelo lube ngokufanayo kwaye lube nengqiqo kwaye lunciphise ngakumbi ubukhulu besakhiwo.

QHAGAMSHELANA NGOKU

Iinkcukacha

Ukuqamba

Iintambo ze-ankile ngokubanzi zenziwe ngeentambo zocingo, iiankile, izinto ezicinezelekileyo, njl.

1.Intambo yocingo

Intambo yentsimbi yenye yezona zinto zibalulekileyo zentambo yeankile. Iqulunqwe ngeentambo ezininzi zeentambo zentsimbi. Umsebenzi wayo oyintloko kukumelana nokunyanzeliswa kwentambo ye-anchor, kwaye ngelo xesha kufuneka ibe neqondo elithile lokuqina ukujamelana nokutshintsha kwendawo yangaphandle.

2.Iiankile

I-anchor yenye inxalenye ebalulekileyo yentambo ye-anchor. Ikakhulu isetyenziselwa ukulungisa intambo yocingo emhlabeni okanye ematyeni ukuthintela ukutsalwa okanye ukutyibilika. Ukukhethwa kwezinto kunye noyilo lwee-ankile kufuneka kuthathelwe ingqalelo izinto ezahlukeneyo ezifana neemeko zejoloji, ukuxinana kwentambo ye-ankile kunye namandla angaphandle.

3.Uxinzelelo

Uxinzelelo kuyindlela yokufumana amandla ongezelelweyo kwinkqubo yesakhiwo ngendlela yoxinzelelo lwentambo ye-anchor. Iintambo ze-ankile ezicinezelekileyo zidla ngokusetyenziswa kwiibhulorho ezinkulu, unyango lwesiseko, imingxuma yesiseko enzulu, ukugrumba itonela kunye neeprojekthi zenyikima. Yandisa umthamo wokuthwala umthwalo wenkqubo yesakhiwo ngokuguqula uxinzelelo oluxinzelelekileyo kwintambo yentsimbi yentsimbi kwi-prestress yekhonkrithi okanye ilitye.

4.Ezinye izixhobo ezincedisayo

Ukongeza kwiintambo zocingo, i-anchor kunye ne-prestressing forces, iintambo ze-anchor nazo zifuna ezinye izinto ezincedisayo, ezifana neetyhubhu zokukhusela intambo ye-anchor, amavili esikhokelo, izixhobo zoxinzelelo, njl., Ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko lweentambo ze-anchor.

Inkqubo yokuFakela

1.Umsebenzi wokulungiselela

1.1: Misela indawo yobunjineli kunye nobude bentambo ye-anchor.

I-1.2 : Lungiselela ukucaciswa kunye nendlela yokuxhatshazwa kwentsimbi yentsimbi.

1.3: Lungisa izixhobo ezifunekayo kunye nezixhobo, ezifana noomatshini bokuphakamisa, njl.

1.4: Qinisekisa ukuba indawo yokusebenza ikhuselekile.

2.Ufakelo lweAnchor

2.1: Misela indawo yokufakela i-anchorage, kwaye uqhube ukukhangela umhlaba kunye nokumakisha.

2.2: Gqoka imingxuma kwaye ucoce uthuli, umhlaba kunye nobunye ukungcola emingxunyeni.

2.3: Faka i-anchor, faka i-anchor emngxunyeni kwaye uthele ikhonkrithi ukuze uqiniswe ukuqinisekisa ukuba i-anchor iqinile.

2.4: Uvavanyo lomthwalo kufuneka lwenziwe emva kokufaka i-anchor ukuqinisekisa ukuba i-anchor inokumelana nomthwalo olindelekileyo.

3.Ukufakwa kwentambo

3.1: Fakela izincedisi ezifana nezibophelelo kunye neepads kwi-ankile.

3.2: Faka intambo, faka i-strand yensimbi kwi-anchor kwangaphambili, gcina ukunyanzeliswa okuthile, kwaye ugcine i-verticality kunye ne-flatness yentambo.

3.3: Sebenzisa izixhobo ezikhethekileyo zokuqinisa intambo de ukuxhatshazwa kufikelele kwiimfuno zoyilo.

4.Uxinzelelo

4.1: Faka i-tensioner kwaye udibanise iintambo.

4.2: Uxinzelelo ngokweemfuno zoyilo de kufike amandla afunekayo okulayisha kwangaphambili.

4.3: Ngexesha lenkqubo yoxinzelelo, intambo nganye kufuneka ibekwe esweni ukuqinisekisa ukuba amandla oxinzelelo ahlangabezana neemfuno.

4.4: Uxinzelelo ngokwenqanaba loxinzelelo oluchaziweyo, kunye nokwenza i-tensioning kunye nokutshixa xa iimfuno zihlangatyezwa.

Ukwamkelwa

Emva kokuba intambo ye-anchor ifakwe, ukwamkelwa kufuneka kuqhutywe, kubandakanywa ukuhlolwa komthwalo, ukuhlolwa okubonakalayo, ukulinganisa kunye nokuvavanya, njl. Qinisekisa ukuba ukufakwa kwentambo ye-anchor kuhambelana nemigangatho efanelekileyo kunye neemfuno, kwaye inokusetyenziswa kuphela. emva kokuphumelela ukuhlolwa kokwamkelwa.

Inzuzo

1. Amandla e-ankile aphezulu:

Zombini i-prestressing kunye ne-anchoring epheleleyo ingasetyenziswa, kwaye ubunzulu be-anchoring bunokukhethwa ngokukhululekileyo.

2.Inani eliphezulu leiankile, ukhuseleko oluphezulu:

Inzuzo yesi sakhiwo se-anchor kukuba nangona impembelelo ye-anchoring yesinye sentsimbi yentsimbi ilahlekile, ukungaphumeleli kwe-anchorage jikelele akuyi kwenzeka, kunye nenqwaba yeentambo zetsimbi Inani lokungena aliyi kulinganiselwa.

3.Uluhlu olubanzi lwesicelo:

Ii-ankile zisetyenziswa ikakhulu kwiiprojekthi zokwakha ezifana nezakhiwo zezindlu, iiprojekthi zolwakhiwo lweebhulorho, amadama namazibuko, iiprojekthi zogcino lwamanzi, izikhululo zombane kunye namanye amabala okwakha ubunjineli.

4.Inokusetyenziswa ngokusisigxina:

izinto eziphathekayo ziyakwazi ukumelana ne-corrosion kunye ne-rust-resistant, zizinzileyo kwaye zihlala ixesha elide, kwaye zigcina iindleko zempahla.

5.Into yokhuseleko oluphezulu:

Idlala indima ezinzileyo kwaye ekhuselekileyo kwisakhiwo kwaye iyikhonkco ebalulekileyo yokwakha ekwakhiweni.
