Basalt Fiber Kusimbisa muInoshanda Injiniya Zvikumbiro uye Tsvagiridzo

1.Basalt Fiber kusimbiswa mumigwagwa yekongiri

Inoramba ichisimbisa kongiri pavements inodzora kutsemuka nekuda kwekuderera nekuisa nhamba yakakwana yemabhawa ekusimbisa munzira yelongitudinal. Iyi dhizaini haingo wedzere kurodha uye kusimba kwemugwagwa mukuru asi zvakare inovandudza nharaunda yekutyaira yemotokari nekusapa ekuwedzera uye majoini ekumisikidza panguva. Kuvaka. Zvisinei, sezvo chimiro chegwagwa chisingagoni kuvharwa zvachose, zvinhu zvakadai sokupinda kwemvura inonaya uye chando chechando chinogona kutungamirira mukuora kwesimbi yekusimbisa, iyo inokanganisa zvakanyanya hupenyu hwebasa remugwagwa.

Basalt fiber kusimbaradza kunogona kushandiswa panzvimbo yechinyakare simbi yekusimbisa yekuramba yakasimbiswa kongiri pavement nekuda kweiyo yakanakisa corrosion kuramba uye yakakwirira tensile simba. Iyi imwe sarudzo inogadzirisa zvinogadzirisa dambudziko resimbi corrosion, nokudaro zvakanyanya kuvandudza kusimba kwekongiri pavement. Pamusoro pe, basalt fiber kusimbiswa ndekwezvinhu zvakaderera-kabhoni uye zvakatipoteredza, uye mutengo wayo wemutengo unowedzera uye unowedzera kuoneka nekuderera kwesimbi zviwanikwa. Zvidzidzo zviripo zvakaratidza kuti kushandisa BF-RP yekusimbisa mumakongiri pavement kunoratidza mabhenefiti ari pachena maererano nekusimba uye kusagadzikana kwemarara, uye kuoma kwekuvaka uye kufambira mberi kunofananidzwa neiyo yekusimbisa simbi. Nekudaro, nekuda kweiyo yakaderera modulus ye elasticity yeBF-RP yekusimbisa, zvinofanirwa kuwedzera zvishoma kusimba kwayo reshiyo, kazhinji pakati pe0.78% ne1.0%, uye kutora pfungwa yekugadzira ye "diki yekusimbisa dhayamita uye kuvhara nzvimbo".

2.Tsvagiridzo yebasalt fiber kusimbisa mukusimbisa mapfupi kongiri eccentric compression makoramu

Nzira dzechinyakare dzekusimbisa dzinowanzo shandisa simbi yekunze, asi nzira iyi inonetsa mukuvaka uye ine kushomeka kwekudzivirira kupisa kwakanyanya uye ngura. Izvo zvisingaremi, yakakwirira-kusimba, yakakwirira-yekushisa uye inodzivirira-corrosion-resistant properties yebasalt fiber zvinhu zvinounza sarudzo itsva yekusimbisa nzira. Parizvino, iyo yekusimbisa tekinoroji yebonded basalt fiber mapepa akakura, asi tsvakiridzo yekuvandudza flexural mutoro simba rekongiri makoramu nekumisikidza basalt fiber tendons idiki. Mabhuku akakodzera anoratidza izvozvo basalt fiber kusimbaradza kunonatsiridza zvakanyanya lateral kubhenda kugona kwekongiri makoramu uye inogona kuwedzera kusimudzira mutoro wekutakura nekubatanidza nzira yekuburitsa basalt fiber jira.

Iyo yekuvaka inoteedzana yakamisikidzwa basalt fiber reinforcement ndeiyi inotevera:

1. Vhura groove maererano nehukuru hwekugadzira
2. Geza groove
3. Isa bonding agent (epoxy resin adhesive)
4. Embedding BF-RP mbariro
5. Zadza nebhainda zvakaenzana
6. Mirira kuti binder apore uye wozoita mushonga wepamusoro.

Nekubatanidza neiyo kunze basalt fiber jira, iyo BF-RP yekusimbisa inogona kunyatso dzivirira chiitiko chekutsvedza uye spalling mukuita kwekunetsekana, kuvakwa kuri nyore uye kunoshanda, uye kunotora nzvimbo shoma, iyo ine mabhenefiti asingaenzaniswi.

3.Basalt fiber yakasimbisa kongiri matanda

BF-RP yekusimbisa ndeye hushamwari kwezvakatipoteredza, yakakwirira-yakasimba isiri-simbi yekusimbisa zvinhu ine zvivakwa zvakaita secorrosion resistance, electromagnetic insulation, uye kuneta kuramba, zvichiita kuti ive imwe yakasarudzika nzira yekusimbisa simbi mune mamwe mapurojekiti akakosha. Zvisinei, kusiyana nesimbi yakajairwa mbariro, BF-RP mbariro hadzina yakakosha goho poindi uye ine yakaderera modulus elasticity, izvo zvinogona kukonzera kutsauka kukuru kwekongiri matanda akaiswa pamutoro wakafanana. Kunyangwe kukuvadzwa kwekongiri neBF-RP kusimbiswa kwakaoma uye hakuna fungidziro iri pachena, inoburitsa deformation yakakura isati yakuvadzwa, iyo inopa yambiro yekuchengetedzwa kwemaitiro.

Kana chivako chacho chiine zvakanyanya kuomesera zvinodiwa zvekrete yekrete, zvakakosha kufunga nezvekushandisa prestressing kune basalt fiber tendons, kana kuwedzera modulus yavo ye elasticity, uye kusanganisa uye kuenzanisa nesimbi yekusimbisa kuti ive nechokwadi chekugadzikana uye kuchengeteka kwechimiro.
