I-Polyethylene egqunyiweyo Hlala kwiCable/Galvanized parallel wire cable
Intshayelelo
IFransi ikhuphe i-NFA-35-035 "Hot-dip galvanized kunye ne-zinc aluminium alloy prestressed steel wire kunye nentsimbi ephothiweyo". Umgangatho ugubungela i-diameter ye-5.0mm, 6.0mm, 7.0 mm kunye nebhulorho yokumiswa ngokulandelelanayo. Iimpawu eziphambili zezobugcisa ze-galvanized / zinc aluminium alloy coated steel wire ziboniswe kwitheyibhile.
Ulwakhiwo
Ziquka iipleyiti ezithwala imithwalo, iiplate ze-wedge kunye ne-wedges. Faka i-tendon kwi-ankile kwaye uqhube i-wedge kwi-wedge plate ukuze ubambe i-tendon endaweni. Izikhonkwane zoxinzelelo lwendiza zifumaneka kwiindlela ezahlukeneyo zokucwangciswa, njengama-anchors e-single-strand kwintsimbi enye yentsimbi kunye ne-multi-strand anchors kwimivalo emininzi. Zibalulekile ekuqinisekiseni ukuhanjiswa okusebenzayo kwe-prestress kwikhonkrithi, ukubonelela ngokunyaniseka kwesakhiwo esifunekayo kwisicelo.

Iimbonakalo
Ucingo lwensimbi luhlulwe kwiKlasi A kunye ne-B. I-Class A wire yensimbi isetyenziselwa kakhulu kwiimveliso ezigxininisiweyo ezinokhuseleko oluncinci kunye nomthwalo omncinci ophilayo. Ukumelana nokukhathala kwayo kufuna i-0.70σb umda woxinzelelo kunye ne-200 MPa. kunye ne-2 yezigidi zemijikelezo. I-Class B yentsimbi yentsimbi isetyenziselwa ikakhulu iintambo zebhulorho ezinokhuseleko olukhulu kunye nomthwalo omkhulu ophilayo. Ukumelana nokukhathala kwayo kufuna i-0.45σb kunye noxinzelelo lwe-amplitude ye-300 MPa kunye ne-2 yezigidi zemijikelezo. Ngelo xesha, umgangatho uphinda uchaze inani lokugoba ngokuphindaphindiweyo ucingo ukuvavanya iplastiki yocingo.
Iluncedo
Intambo yebhulorho yindlela yokuphila yebhulorho enqunyanyiswayo enobude obukhulu okanye ibhulorho enentambo enqumla ulwandle nomlambo. Ukuxhatshazwa kwe-corrosion yocingo lwayo lwensimbi kubaluleke kakhulu ekukhoneni kunye nokhuseleko lwesakhiwo. Umgangatho wahlula umsebenzi wokugquma wocingo lwentsimbi kwiindidi ezine:
(1) umgangatho wokugquma kwindawo nganye yeyunithi yocingo lwentsimbi;
(2) amandla okuncamathela kwengubo;
(3) ukuqhubeka kwengubo; kwaye
(4) ezinye iinkalo. Umgangatho ufuna ukuba umgangatho wendawo yokugubungela kwindawo nganye yeyunithi yocingo lwetsimbi kufuneka ube yi-180 ~ 350 g / m2, ubuninzi bengubo bubalwa ngokwe-7.2 g / cm3, kwaye ubukhulu becala kufuneka bube yi-26 ~ 49μm. Indlela yokuhlola umgangatho wentsimbi yokugquma ucingo ngemitha yesikwere iya kuba yiNF EN1460, kwaye ubude besampulu yovavanyo abuyi kuba ngaphantsi kwe-150 mm. I-polyethylene eNgqunyiweyo yokuhlala intambo / intambo yocingo oluyi-galvanized parallel iveliswa ngokujija intambo yentsimbi enamandla amakhulu. kwaye emva koko ugqume ucingo olujijekileyo kunye ne-polyethylene ephezulu kunye nenkqubo eshushu ye-extrusion. I-lt isetyenziswa ngokubanzi njengentambo ye-cable ehlala ibhulorho, intambo yokubopha, i-hanger ye-orch bridge, i-suspender yebhulorho yokuxhoma kunye nentambo ye-struduer ekhethekileyo.
Ikheyibhile yoxinzelelo lokungcangcazela kwemvula yomoya
Ikhebula lokuhlala lilinye lamacandelo abalulekileyo kwiibhuloho ezihlala kwi-cable kwaye ziyakwazi ukungcangcazela njengoko ubude bazo bunyuka.Ezi ntambo zenzelwe ukunciphisa ukunyakaza okubangelwa ngumoya.Oku kwandisa ubomi bokusebenza kwebhuloho kwaye kunika ukhuseleko olongezelelweyo.
Ikhebula ene-helical wire kabini
Iingcingo eziphindwe kabini ze-helical kumphezulu wentambo yokuhlala kunye nobude obuchaziweyo kunye ne-pitch ithintela umoya wemvula obangela ukungcangcazela.Le teknoloji isetyenziswe ngempumelelo kwiiprojekthi zebhulorho, ezifana ne-Edong Yangtze River Bridge, i-Shenzhen Bay Bridge, i-Indonesia Suramadu Bridge, i-Jianbang Bridge. kwaye nangokunjalo.
Intambo yokuqina ephezulu yokuqina
Ngokwesiseko sentambo yokuhlala eqhelekileyo, i-ultra-high-amandla ehlala ixesha elide (ibakala lamandla ukuya kuthi ga kwi-1770MPa, 1860MPa kunye ne-1960Mpa) intambo iye yandiswa bubomi benkonzo kwiminyaka engama-50 phantsi kweemeko eziqhelekileyo ngokusebenzisa imathiriyeli engcono ekrwada, ukuphucula iindlela zokuvelisa. kunye nesakhiwo sentambo.
Isetyenzisiwe kwiBhulorho yaseSutong, iBhulorho yaseHong Kong Stonecutters, iBhulorho yaseZhujiang Huangpu, iBhulorho yaseJiashao, iBhulorho yaseHongKong-Zhuhai-Macau njl.
Intambo ende kunye nenkulu
Ngokwakhiwa kweebhulorho ezihlala ngekhebula kunye nobude bawo obungaphezulu kwe-100m, iimfuno zokuhlala kwentambo ziba phezulu kwaye ziphezulu ngobude kunye nokusebenza. Okwangoku, inkampani yethu inokuvelisa intambo yokuhlala ehlala ixesha elide kunye nenkulu enobude obungaphezulu kwe-800m kwaye obona bukhulu bukhulu bunokufikelela kwi-511p7.Sikuphela komenzi oqeqeshiweyo onamandla okuvelisa intambo emide kune-500m.
