Yakadzama Tekinoroji Mapoinzi eBasalt Fiber Yakaramba Yakasimbiswa Inosanganiswa Pavement Kuvaka
I. Preprocessing uye Positioning yeComposite Reinforcement Rolls
1. Kuchengetera uye Kuburitsa kweReinforcement Rolls
- Zvinotsanangurwa: Imwe neimwe roll ye basalt fiber composite kusimbisa inoyera 600 m kureba uye inorema 18 kg.
-Kubata: Chengetedza rolls zvakachinjika mumafuremu akatenderera. Bvisa iyo yekurongedza yekunze uye nyatso tungamira iyo yekusimbisa kuguma kune yakasarudzwa chinzvimbo kuti urege kumonyoroka kana kukotama.
2. Baseline Surveying
-Shandisa chiteshi chese kana laser alignment yemidziyo kunyatso nyora zvinzvimbo zveiyo composite yekusimbisa mesh nenzvimbo dzakabatanidzwa zvichienderana nedhizaini yedhizaini. Mapoinzi ekudzora akakosha anofanirwa kuzivikanwa zvakajeka.
II. Kuiswa uye Kusunga kweComposite Reinforcement Mesh
1. Transverse Reinforcement Installation
- Isai anochinjika anosimbisa pazvigaro zvekutsigira, kuve nechokwadi che60 ° angle ine longitudinal reinforcements. Sungai magumo zvakachengeteka kudzivirira kutamiswa.
- Kudzora Urefu: The composite reinforcement mesh inofanira kunge yakaderera masendimita gumi pane iyo pavement panel, ine yekunze reinforcement centre inochengetwa ≥90 mm kubva kumakona emahara.
2. Chimiro chekutsigira Kuvaka
- Gadzira U-yakaita simbi inotsigira uchishandisa Φ25 mm ribbed Steel Bars, yakaparadzana 25 cm kureba uye 50 masendimita yakachinjika, kudzikamisa iyo composite yekusimbisa mesh.
- Isa nzvimbo huru-inotakura inoumbwa inosimbisa munzvimbo dzekunyanya kukotama kushushikana, ine transverse reinforcements yakaparadzana 50 cm pazasi pe longitudinal bars.
3. Dziviriro uye Pfeka-Resistant Layers
- Pazasi Dziviriro Layer: Iyo 180 mm gobvu yekudzivirira layer yakaiswa pakati pekusimbisa mesh uye subbase kudzivirira kukukurwa.
- Yepamusoro Kupfeka-Inodzivirira Layer: Iyo 50 mm gobvu inodzivirira kupfeka inoiswa pamusoro pemambure kuti iwedzere kusimba kwepavement.
III. Longitudinal Reinforcement uye Joint Construction Control
1. Longitudinal Reinforcement Spacing uye Precision
- Longitudinal reinforcement spacing inofanira kuva ≤250 mm uye kudarika 2.5 times the peak aggregate size (semuenzaniso, ye10 mm aggregate peak, spacing ≥25 mm).
-Shandisa zvibatiso zvekumisa kuti uve nechokwadi chekuisa, nekutsauka kunodzorwa mukati me ± 5 mm.
2. Longitudinal Joint Tie Bars
- Φ25 mm mbavu dzesimbi dzesimbi dzinoshandiswa kune longitudinal joint tie mabhawa, akarongedzerwa munzvimbo dzakabatana.
- Yakazara-yakafara paving zvikamu zvinogona kusiya longitudinal majoini kubvisa zvimiro zvisina kusimba mapoinzi.
IV. Prestressed Reinforcement uye Support Installation
1. Yakasimbiswa Longitudinal Composite Reinforcement
- Shandisa Φ25 mm simbi mbariro se prestressed longitudinal reinforcements, ane anchorage kureba kwakanyatso kudzorwa pa 3.0 m.
- Kupindirana kureba kunosiyana 60-100 cm, yakachengetedzwa ne epoxy resin mushure mekusunga kuti ive nechokwadi chekubatanidza isina musono.
2. Tsigira Prefabrication uye Fixation
- Prefabricate simbi inotsigira uye lap majoini senge dhizaini. Dhobora maburi **10–15 masendimita kubva kumacheto emahara uye majoini akareba** muchikamu chepasi, zvitsigiso zvakamisikidzwa, uye weld anchor bars.
V. Kuvaka Maitiro uye Kudzora Kwehutano
1. Regulatory Compliance
- Kunyatsoomerera kune GB 50010-2010 (Kodhi yeKugadzira ye Concrete Structures) yekusungirirana, yekudzivirira layer ukobvu, uye mamwe ma parameter.
2. Makiyi Ekugamuchira Akakosha
- Flatness kutsauka kwesimbi yekusimbisa: ≤3 mm / m.
- Ita bvunzo dzekudhonza-kunze pane epoxy resin-yakasungwa nzvimbo, inoda bond simba re ≥2.5 MPa.
VI. Matambudziko Anowanikwa uye Mhinduro
- Nyaya 1: Mesh Misalignment
Solution: Isai zvisungiso zvenguva pfupi uye mafuremu ekumisa pa5 m intervals.
- Nyaya yechipiri: Yakaneta Epoxy Bonding
Solution: Ita shuwa kuti nzvimbo dzekubatanidza dzakachena uye dzakaoma. Dzora tembiricha yekurapa pa15-30 ° C uye nguva yekurapa ≥24 maawa.
