Izindaba - I-Prefabricated Rubber Running Track Subbase Foundation

Ngaphambi kokwakhiwa,ithrekhi yokugijima yerabha eyenziwe ngaphambilinis zidinga izinga elithile lokuqina komhlabathi, ukuhlangabezana nezindinganiso zokuqina ngaphambi kokuba ukwakhiwa kuqhubeke. Ngakho-ke, isisekelo sesisekelo esingaphansi samathrekhi enjoloba akhiwe kusengaphambili kufanele aqiniswe.

Isisekelo Sokhonkolo

1. Ngemva kokuphothulwa kwesisekelo, indawo kasimende akumelwe ibe bushelelezi kakhulu, futhi akufanele kube nezigigaba ezifana nokusantiya, ukuxebula, noma ukuqhekeka.

2. Ukucaba: Izinga lokuphasa lilonke kufanele libe ngaphezu kwama-95%, kube nokubekezelela okungaphakathi kuka-3mm ngaphezu kwe-3m eqondile.

3. Umthambeka: Kufanele uhlangabezane nezicaciso zobuchwepheshe zezemidlalo (umthambeka oseceleni awudluli u-1%, umthambeka we-longitudinal ungabi ngaphezu kuka-0.1%).

4. Amandla acindezelayo: R20 > 25 kg/square centimeter, R50 > 10 kg/square centimeter.

5. Indawo yesisekelo kufanele ingabi namanzi okuvimbela.

6. Ukuminyana: Ukuminyana kobuso kufanele kube ngaphezu kwama-97%.

7. Isikhathi sokunakekela: Ngaphezulu kuka-25°C izinga lokushisa langaphandle izinsuku ezingu-24; phakathi kuka-15°C no-25°C izinga lokushisa langaphandle izinsuku ezingu-30; ngaphansi kuka-25°C izinga lokushisa langaphandle izinsuku ezingu-60 (ukunisela njalo ngesikhathi sokunakekela ukususa izingxenye ze-alkali kusimende oguquguqukayo).

8. Izembozo zomsele kufanele zibe bushelelezi futhi ziguquke kahle ngethrekhi ngaphandle kwezinyathelo.

9. Ngaphambi kokubeka amathrekhi enjoloba akhiwe ngaphambilini, ungqimba oluyisisekelo kufanele lungabi nawoyela, umlotha, futhi lome.

Isisekelo se-Asphalt

1. Isisekelo sesisekelo akumelwe singabi nemifantu, ama-roller marks asobala, amabala kawoyela, amaqatha etiyela angaxutshiwe, aqiniswe, azike, aqhekeke, acwebe uju, noma axebuke.

2. Indawo yesisekelo kufanele ingabi namanzi okuvimbela.

3. Ukucaba: Izinga lokuphasa lokucaba kufanele libe ngaphezu kwama-95%, kube nokubekezelela okungaphakathi kuka-3mm ngaphezu kwe-3m eqondile.

4. Umthambeka: Kufanele uhlangabezane nezicaciso zobuchwepheshe zezemidlalo (umthambeka oseceleni awudluli u-1%, umthambeka we-longitudinal ungabi ngaphezu kuka-0.1%).

5. Amandla acindezelayo: R20 > 25 kg/square centimeter, R50 > 10 kg/square centimeter.

6. Ukuminyana: Ukuminyana komphezulu kufanele kube ngaphezu kwama-97%, amandla omile afinyelele ngaphezu kuka-2.35 kg/litre.

7. Indawo yokuthambisa itiyela > 50°C, ukuphakama okungu-60 cm, ukujula kokungena kwenaliti 1/10 mm > 60.

8. I-asphalt thermal stability coefficient: Kt = R20/R50 ≤ 3.5.

9. Izinga lokunwetshwa kwevolumu: <1%.

10. Izinga lokumunca amanzi: 6-10%.

11. Isikhathi sokunakekela: Ngaphezulu kuka-25°C izinga lokushisa langaphandle izinsuku ezingu-24; phakathi kuka-15°C no-25°C izinga lokushisa langaphandle izinsuku ezingu-30; ngaphansi kuka-25°C izinga lokushisa langaphandle izinsuku ezingu-60 (ngokusekelwe ezingxenyeni eziguquguqukayo ku-asphalt).

12. Izembozo zomsele kufanele zibe bushelelezi futhi ziguquke kahle ngethrekhi ngaphandle kwezinyathelo.

13. Ngaphambi kokubeka amathrekhi enjoloba enziwe ngaphambilini, hlanza isisekelo ngamanzi; ungqimba oluyisisekelo kufanele lungabi namafutha, umlotha, futhi lome.

Ukufakwa Kwethrekhi Yenjoloba Eyakhiwe ngaphambilini

1. Isisekelo kufanele sibe bushelelezi ngokwanele futhi singabi nesihlabathi. Ukuyigaya nokuyibeka ezingeni. Qiniseka ukuthi aweqeli ± 3mm uma ukalwa ngo-2m oqondile.

4. Lapho izinto ezisetshenziswayo zifika esizeni, indawo efanele yokubeka kufanele ikhethwe kusengaphambili ukuze kube lula umsebenzi wokuthutha olandelayo.

7. Sebenzisa isomisi sezinwele ukuhlanza ubuso besisekelo. Indawo ezokwalwa kumele ingabi namatshe, amafutha kanye nezinye izibi ezingase zibe nomthelela ekubopheni.

10. Ngemuva kokuthi imigqa engu-2-3 ngayinye ibekwe, izilinganiso nokuhlolwa kufanele kwenziwe ngokubhekiselwe kumugqa wokwakha kanye nezimo zempahla, futhi amalunga obude bezinto ezihlanganisiwe kufanele ahlale emgqeni wokwakha.

2. Sebenzisa i-polyurethane-based adhesive ukuze uvale ubuso besisekelo ukuze uvale izikhala kukhonkolo ye-asphalt. Sebenzisa izinto ezinamathelayo noma ezisekelwe emanzini ukuze ugcwalise izindawo eziphansi.

5. Ngokusho kokusetshenziswa kokwakhiwa kwansuku zonke, izinto ezihlanganisiwe ezingenayo zihlelwa ezindaweni ezihambisanayo, futhi imiqulu isakazwa endaweni yesisekelo.

8. Uma i-adhesive icwecwa futhi isetshenziswa, ithrekhi yenjoloba egoqiwe ingavulwa ngokusho komugqa wokwakhiwa kwe-paving, futhi isikhombimsebenzisi sigoqeka kancane futhi sikhishwe ku-bond.

11. Ngemuva kokuthi wonke umqulu usulungisiwe, ukusika kwe-seam okuphambene kwenziwa engxenyeni egqagqene egcinwe lapho kubekwa umqulu. Qinisekisa ukuthi kukhona okunamathelayo okwanele ezinhlangothini zombili zamalunga aguquguqukayo.

3. Endaweni yesisekelo esilungisiwe, sebenzisa i-theodolite nerula yensimbi ukuze uthole umugqa wokwakha ogandayiwe wezinto ezigoqiwe, osebenza njengomugqa wenkomba wokugijima kwethrekhi.

6. I-adhesive enezingxenye ezilungiselelwe kufanele ishukunyiswe ngokugcwele. Sebenzisa i-blade eshukumisayo ekhethekile lapho ushukumisa. Isikhathi sokugqugquzela akufanele sibe ngaphansi kwemizuzu emi-3.

9. Ebusweni bekhoyili eboshiwe, sebenzisa ipusher ekhethekile ukuze unciphise ikhoyili ukuze uqede amabhamuza omoya asele phakathi nenqubo yokuhlanganisa phakathi kwekhoyili nesisekelo.

12. Ngemva kokuqinisekisa ukuthi amaphuzu anembile, sebenzisa umshini womaka wochwepheshe ukuze ufafaze imigqa yomzila wethrekhi ogijimayo. Bheka ngokuqondile amaphuzu okufafaza ngawo. Imigqa emhlophe edwetshiwe kufanele icace futhi icwebe, ngisho nogqinsi.
