Xov xwm - Prefabricated Rubber Running Track Subbase Foundation

Ua ntej kev tsim kho,prefabricated roj hmab khiav khiavs yuav tsum muaj qee theem ntawm av hardness, ua tau raws li cov qauv hardness ua ntej kev tsim kho tuaj yeem ua tiav. Yog li ntawd, lub hauv paus subbase ntawm prefabricated roj hmab khiav lem yuav tsum tau solidified.

2. Flatness: Zuag qhia tag nrho pass tus nqi yuav tsum siab tshaj 95%, nrog ib tug kam rau ua nyob rau hauv 3 hli dhau ib tug 3m straightedge.

3. Txoj kab nqes: Yuav tsum ua kom tau raws li cov kev ua kis las tshwj xeeb (kev nqes hav tsis ntau dua 1%, txoj kab nqes ntev tsis ntau dua 0.1%).

4. Compressive zog: R20 > 25 kg/square centimeter, R50 > 10 kg/square centimeter.

5. Lub hauv paus nto yuav tsum tsis muaj dej thaiv.

6. Compaction: Surface compaction ceev yuav tsum tshaj 97%.

7. Lub sijhawm tu: Tshaj 25 ° C sab nraum zoov kub rau 24 hnub; nruab nrab ntawm 15 ° C thiab 25 ° C sab nraum zoov kub rau 30 hnub; Hauv qab 25 ° C sab nraum zoov kub rau 60 hnub (dej nquag thaum lub sijhawm saib xyuas kom tshem tawm cov khoom alkaline los ntawm cov cement tsis hloov).

8. Trench npog yuav tsum du thiab hloov mus rau qhov zoo nrog txoj kev tsis muaj kauj ruam.

9. Ua ntej tso cov roj hmab prefabricated, lub hauv paus txheej yuav tsum tsis muaj roj, tshauv, thiab qhuav.

Asphalt Foundation

1. Lub hauv paus nto yuav tsum tsis muaj kab nrib pleb, pom tseeb cov cim, roj stains, unblended asphalt chunks, hardening, sinking, cracking, honeycombing, los yog tev.

2. Lub hauv paus nto yuav tsum tsis muaj dej thaiv.

3. Flatness: Tus pass tus nqi rau flatness yuav tsum siab tshaj 95%, nrog ib tug kam rau ua nyob rau hauv 3mm tshaj ib tug 3m straightedge.

4. Txoj kab nqes: Yuav tsum ua kom tau raws li cov kev ua kis las tshwj xeeb (kev nqes hav tsis ntau tshaj 1%, txoj kab nqes ntev tsis ntau dua 0.1%).

5. Compressive zog: R20 > 25 kg/square centimeter, R50 > 10 kg/square centimeter.

6. Compaction: Surface compaction ceev yuav tsum tshaj 97%, nrog rau qhuav muaj peev xwm ncav cuag tshaj 2.35 kg/liter.

7. Asphalt softening point> 50 ° C, elongation 60 cm, koob nkag qhov tob 1/10 mm> 60.

8. Asphalt thermal stability coefficient: Kt = R20/R50 ≤ 3.5.

9. Volume expansion npaum li cas: <1%.

10. Kev nqus dej: 6-10%.

11. Lub sij hawm tu: Tshaj 25 ° C sab nraum zoov kub rau 24 hnub; ntawm 15 ° C thiab 25 ° C sab nraum zoov kub rau 30 hnub; Hauv qab 25 ° C sab nraum zoov kub rau 60 hnub (raws li cov khoom tsis haum hauv asphalt).

12. Trench npog yuav tsum tau du thiab hloov mus smoothly nrog txoj kev tsis muaj kauj ruam.

13. Ua ntej tso cov roj hmab prefabricated khiav, ntxuav lub hauv paus nto nrog dej; lub hauv paus txheej yuav tsum tsis muaj roj, tshauv, thiab qhuav.

Prefabricated Rubber Running Track Installation

1. Lub hauv paus yuav tsum du txaus thiab tsis muaj xuab zeb. Sib tsoo thiab leveling nws. Nco ntsoov nws tsis tshaj ± 3 hli thaum ntsuas los ntawm 2m straightedges.

4. Thaum cov ntaub ntawv tuaj txog ntawm qhov chaw, qhov chaw tso cai tsim nyog yuav tsum tau xaiv ua ntej kom yooj yim rau kev thauj mus los tom ntej.

7. Siv lub tshuab ziab plaub hau los ntxuav qhov chaw ntawm lub hauv paus. Lub cheeb tsam yuav tsum tau khawb yuav tsum tsis muaj pob zeb, roj thiab lwm yam khib nyiab uas yuav cuam tshuam rau kev sib txuas.

10. Tom qab txhua 2-3 kab tau muab tso rau, kev ntsuas thiab tshuaj xyuas yuav tsum tau ua nrog kev siv cov kab kev tsim kho thiab cov khoom siv, thiab cov kab sib txuas ntev ntawm cov ntaub ntawv coiled yuav tsum nyob ntawm txoj kab kev tsim kho.

2. Siv polyurethane-raws li adhesive los khi rau saum npoo ntawm lub hauv paus kom kaw qhov khoob hauv cov pob zeb asphalt. Siv cov nplaum nplaum los yog cov khoom siv hauv dej los sau cov chaw qis.

5. Raws li kev siv niaj hnub siv, cov khoom siv coiled tuaj yeem raug teeb tsa hauv qhov chaw sib thooj, thiab cov yob tau nthuav dav rau ntawm lub hauv paus nto.

8. Thaum cov nplaum nplaum yog khawb thiab siv, cov roj hmab rub tawm tuaj yeem nthuav tawm raws li cov paving siv kab, thiab lub interface yog maj mam dov thiab extruded rau daim ntawv cog lus.

11. Tom qab tag nrho cov yob yog tsau, transverse seam txiav yog ua nyob rau hauv overlapped feem reserved thaum lub yob yog nteg. Nco ntsoov tias muaj cov nplaum txaus ntawm ob sab ntawm cov pob qij txha transverse.

3. Ntawm qhov chaw kho lub hauv paus, siv theodolite thiab steel kav los nrhiav cov paving siv kab ntawm cov khoom siv dov, uas ua haujlwm raws li qhov taw qhia kab rau kev khiav.

6. Cov nplaum nplaum nrog cov khoom npaj yuav tsum tau nplawm tag nrho. Siv ib rab riam tshwj xeeb nplawm thaum nplawm. Lub sijhawm stirring yuav tsum tsis pub tsawg tshaj 3 feeb.

9. Nyob rau saum npoo ntawm cov coil sib txuas, siv lub zog tshwj xeeb los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov npuas npuas uas tseem tshuav thaum lub sij hawm sib txuas ntawm lub kauj thiab lub hauv paus.

12. Tom qab paub meej tias cov ntsiab lus yog lawm, siv lub tshuab cim kev tshaj lij los txau cov kab khiav khiav. Ua tib zoo saib xyuas cov ntsiab lus tseeb rau kev txau. Cov kab dawb kos yuav tsum meej thiab nkig, txawm nyob hauv tuab.
