1. Hom Load-Cov Kabmob
Rau feem ntau siv HDPE paving phaj:
Lub teeb- cov phaj haujlwm (20–30 mm thickness)
→ Yuav ua tiav20-40 tonsstatic load (cov ntaub ntawv faib tawm)
Nruab nrab- cov phaj ua haujlwm (40–60 mm thickness)
→ Yuav ua tiav40-80 tonsstatic load
Heavy-cov ntawv ua haujlwm muaj zog (Ntau dua lossis sib npaug li 60 hli, ribbed lossis cov qauv sib xyaw)
→ Yuav ua tiav80–{1}} tons, nyob ntawm tus tsim (feem ntau siv rau cranes lossis mining tsheb)
2. Cov ntsiab lus tseem ceeb cuam tshuam rau lub peev xwm thauj khoom
(1) Thickness
Load peev nce nonlinearly nrog thickness:
Muab ob npaug rau thickness tuaj yeem ua rau muaj kev tiv thaiv los ntawm3–5×vim bending txhav.
(2) Kev them nyiaj yug subgrade
Qhov no yog qhov tseem ceeb:
Zoo -compacted gravel puag→ tag nrho load peev xwm ua tau
Mos av / av nkos→ muaj peev xwm yuav poob los ntawm30–70%
(3) Load Hom
Static load (cov khoom siv nres)→ siab dua
Dynamic load (tsav tsheb)→ txo lub peev xwm vim muaj kev cuam tshuam thiab qaug zog
(4) Phaj Tsim
Solid Sheet vsribbed / honeycomb reinforced qauv
Interlocking systems faib load hla ntau daim hlau
3. Cov Khoom Siv Khoom Siv (HDPE)
Compressive zog:20-30 MPa
Flexural Modulus:~ 800-1500 MPa
Kev cuam tshuam zoo heev → haum rau kev rov ua haujlwm hnyav
4. Cov qauv siv tswv yim engineering
Kev tsim kho ib ntus→ 40-60 tuj tsheb ✔
Roj & roj / mining nkag→ 80-120 tuj tsheb ✔
Crane outrigger pads (engineered daim hlau)→ 100+ ton (nrog rau lub hauv paus)
5. Tseem ceeb Engineering Note
Yog tias koj tab tom tsim rau cov haujlwm tiag tiag (tshwj xeeb yog mining lossis hnyav logistics), koj yuav tsum tsis txhob cia siab rau nominal "tons" ib leeg. Xwb, xam:
Ground bearing siab (kPa)
Phaj deflection txwv
Kev nyab xeeb yam (Ntau dua lossis sib npaug rau 2.0 pom zoo)
