Ukukhetha indaba yokwakhiwa kwezindlela zasendlini nendawo yangakini, akufanele ucabangele amakhono ayo okuhlobisa kuphela, kodwa futhi ukuqina nokusebenza.
Amathayili angaba nobuhlobo obuhlukene, ubukhulu, imibala, ubukhulu nezakhiwo, kodwa kufanele abe namandla amakhulu nokumelana nezimo zangaphandle ezimbi. Izakhiwo ezinjalo zibhekwa ngamatyela wamapulangwe anamuhla e-polymer. Lezi zinto zishesha, kodwa sekuvele zikwazi ukuzibonakalisa kahle.
Ubuchwepheshe bokukhiqiza kanye nokukhetha kwezinto zokusetshenziswa
Ukwakhiwa kwamatayela e-polymer sanding paile kufaka izingxenye ezintathu kuphela:
- Sand (cishe 75%);
- I-propylene ephakeme kakhulu noma i-propylene;
- Amadayimu asuka kumvelo.
Ukuthungwa namandla wezinto eziphathekayo kuxhomeke emgangathweni wezinto ezisetshenziswayo. Enkambweni yokukhiqiza, ukunakwa okukhethekile kubhalwa ngokuyinhloko kwekhwalithi yesihlabathi. Ngaphambi kokusetshenziselwa, kuhlanzwa kahle, kuhlanganisiwe futhi kukhonjwe emazingeni aphezulu okushisa. Ubukhulu bezinhlayiya zibaluleke kakhulu, ngakho-ke, isihlabathi sobukhulu obuphakathi sikhethiwe.
Ngemuva kokuxuba zonke izithako ukuze kusetshenziswe umbala nombala ohlukile, ingxube ithunyelwa ku-extruder ekhethekile, lapho iphinda ixubaniswe futhi iyancibilika. Khona-ke ingxube ithunyelwa ngaphansi komshini kanye namacwecwe wesayizi oyifunayo kanye nomumo okwakhiwa kuwo.
I-tile enjalo ingamelana nokushisa kwehle kuze kufike ku -70 ° C ngenkathi ingaphazamisi futhi ingaphazamisi ngokungafani ne-polymer isihlabathi sokhonkolo ekhoneni tile.
Izici kanye nezakhiwo zento
I-polymer tile yesikhulumi se-sidewalk inezici ezilandelayo nezinzuzo:
- Izinga eliphezulu lokumelana nokugqoka nokuqina;
- ukumelana kwamanzi (umswakama awungena ngaphakathi, kodwa uhlanganisa emhlabathini ngendlela yamaconsi);
- ukumelana nemidiya enobudlova yamakhemikhali;
- isisindo esincane;
- ukumelana nokushisa okuphansi okumangalisayo;
- lula ukufakwa;
- izinhlobo ezihlukahlukene, ubukhulu kanye nemibala yezingxenyana.
Kodwa kufanele kukhunjulwe ukuthi ukwaziswa kungakhula ngaphansi kwethonya lamazinga okushisa aphezulu, ngakho ukubeka i-polymer sandwich ehamba ngamateyili kwenziwa ngokucabangela izikhala ezidingekayo.
Izimfihlo zokufakwa
Izici ze-polymer tile tile zivumela ukuzisebenzisa kokubili izimo zasemadolobheni kanye nokuhlelwa kokuhlala kwehlobo. Umsebenzi wokulungiselela uqala ngesisekelo lapho ubuchwepheshe bokubeka buzoxhomeke khona. Kungaba ngezinhlobo ezimbili: isihlabathi noma igravel.
Ukubeka ngesisekelo sesihlabathi kwenziwa ngendlela efanayo:
- Kusukela ensimini lapho kuzobekwa khona, indawo ephakeme yomhlabathi (15-20 cm) isusiwe.
- Khona-ke i-base ishicilelwe futhi igxilwe ngokucabangela umthamo.
- Emaphethelweni kwenziwa ama-curbs akhethekile, aphakamisa ungqimba weshlabathi ku-5cm, amanzi achithekile futhi agxilwe.
- Ukumaketha kwendwangu kwenziwa, bese kulandela ukufakwa kwamatshe.
- Uhlaka lwe-geotextile elinama-15-20 cm lubekwe phezulu enhlabathini ehlanganisiwe.
- Kusukela phezulu, kumcengezi we-geotextile, isendlalelo sesandla siyathululelwa, khona-ke kuchithelwa ngamanzi, kuhlanganiswe futhi kusulwe. Kunezigaba eziningana zaloluhlobo.
- Ngaphezu kwalokho, lezi tile zibekwa ngegebe lika-3-5 mm futhi lihambelane ngokusebenzisa isando senjoloba.
- Izigxobo zigcwele isihlabathi ngemva kokubeka.
Ukubeka engxenyeni yama-gravel kuhlinzekela ukuqaliswa kwamaphuzu okuqala angu-4, bese kuthi indawo igcwale ngamatshe aqoshiwe futhi ahlanganiswe. Ilitshe elichotshoziwe lichitheka nge-screed ka-5-10 cm. Ama-tile abekwa ingxube ekhethekile yeglue noma ikhonkrithi (ungqimba ka-2-3 cm), izigxobo zigcwele isihlabathi noma ingxube eyomile yokhonkolo nesihlabathi. Ngemuva kokumiswa okuphelele, kufanele kusulwe nge-brush eqinile.
