Ibhuloho le-Qinghai Kuo Ma Ri elinekhebula
- Ibhuloho elihlala ngekhebula i-Kuo Mari litholakala ku-Tongren County Kuo Mari Road ngaphesheya koMfula i-Longwu, iyisifunda esisenyakatho yomgwaqo omkhulu oyindandatho. Ubude obuphelele bungamamitha angu-590, okwakhiwa izingxenye ezimbili: isandiso sasempumalanga nesentshonalanga se-Kuomari Road kanye nebhuloho eliwela umfula, ibhuloho elikhulu lingamamitha angu-200 ubude. Ibhuloho eliyinhloko ibhuloho elihlala ikhebula elinombhoshongo owodwa elinesikhala esiphindwe kabili elinebhuloho elihlala ikhebula elinepylon emise okwedayimane. Amabhuloho okusondela ezinhlangothini ezisempumalanga nasentshonalanga kukhona amabhuloho anokhonkolo acindezelwe ngaphambili akhiwe ngamabhuloho amabhokisi amancane. Inkampani yethu ikakhulukazi ihlinzeka ngezintambo zensimbi eziphumulele eziphansi kanye namasistimu okuhlala anekhebula elihlanganiswe nge-epoxy likakhonkolo webhuloho.Kunamapheya angu-14 (okungukuthi ama-bundle angu-28) ezintambo ezihlala izintambo kulo lonke ibhuloho, nesikhala esijwayelekile esingamamitha ayisi-6 kanye nobude bekhebula obukhulu obungamamitha angama-222.34. Ikhebula elihlala ikhebula lenziwe ngomucu wensimbi ongu-φ15.2mm epoxy coated, ohlukaniswe waba izici ezi-3, inyanda ngayinye yekhebula elihlala ikhebula lakhiwe ngamathenda ensimbi angama-31, 37 kanye nama-43, kanye nomzimba wekhebula eligcwele ukugqwala. yokuvikelwa kwe-HDPE ye-double layer, futhi i-helix igxilwe ebusweni bezintambo zokuhlala futhi i-damping eyakhelwe ngaphakathi ingeziwe.
- Ikhebula elihlala ikhebula lihlelwe ngendlela ye-fan yesikhala ngendlela yebhande eliyinhloko kanye nombhoshongo webhuloho. Ukuphela kokungezwani kuhlelwe kugongolo oluyinhloko, futhi isihlalo sekhebula sepayipi lokuhlukanisa intambo sihlelwe embhoshongweni wekhebula, futhi isihlalo sekhebula lokuqondisa siyamukelwa odongeni lombhoshongo ngendlela yokubambelela, futhi intambo ehlala ikhebula ixhunywe ne-beam eyinhloko futhi ibambelele ebhulokhini lehange ngaphandle kwe-longitudinal beam.
- Izakhiwo zemishini zemicu yensimbi esetshenziswe kuphrojekthi kakhonkolo ocindezelwe ngaphambili kanye namahinge ensimbi e-epoxy ezintambo zebhuloho ahlangabezana nezidingo ze-EN10138-3, GB/T5224 kanye ne-ASTM A416, futhi ukusebenza kwe-anti-corrosion kuhlangabezana nezidingo ze-ISO 14655, I-GB/T 2583-2010 kanye ne-ASTM A 882/A882M-02a "I-Monofilament Coated Epoxy Coated Prestressed Steel Strands"; Ukusebenza kwehange kuhlangabezana nezidingo ezijwayelekile ze-GB/T14370-2015 "Amahange, Ama-Clamps kanye Nezixhumi ze-Prestressed Tendons".Ngenxa yokuthi le phrojekthi iyisakhiwo sekhebula elinombhoshongo owodwa wekhebula elihlala kabili, ibhande lebhokisi lithatha ubuchwepheshe bokwakha bokuthulula ingxenye kakhonkolo ngesigaba sengxenye enkulu yebakaki. Inani lomsebenzi likhulu futhi isikhathi sokwakha sihlangene, ukuze kuqinisekiswe inqubekelaphambili eshelelayo yokwakhiwa futhi kuphothulwe ngeshejuli noma ngaphambi kwesikhathi esimisiwe, kuhlelwe ukuthi lezi ezimbili ezisebenza ngokulinganayo zibhekane nhlangothi zombili zohlangothi oluphambanayo lwesakhiwo. ibhuloho ayalingana ngesikhathi esifanayo ukuze kwakhiwe izinyanda ezimbili zezintambo ezihlala ikhebula.
