1. Core Technical Parameters: Pw lub hauv paus rau qhov project zoo
Technical parameters ntawmpebblepermeable pavement ncaj qha txiav txim siab nws cov dej permeability, load-cov kabmob muaj peev xwm, thiab kev pabcuam lub neej, thiab cov cim qhia tseem ceeb yuav tsum raug txhais raws li cov ntsiab lus ntawm "kev ua raws li ib puag ncig, kev ua tau zoo, thiab kev lag luam rationality".
1.1 Particle Size Ratio: 5-15mm raws li Dominant Range
Txhawm rau sib npaug dej -permeable pore tsim thiab pavement structural stability, pebbles nyob rau hauv lub 5-15mm particle loj ntau yam yog pom zoo, nrog ib tug pom zoo piv ntawm 3:4:3 rau 5-8mm, 8-12mm, thiab 12-15mm hais raws. Qhov kev sib piv no tsim cov dej tsis tu ncua, cov dej-permeable channel, tsis txhob pore clogging los ntawm cov khoom me me los yog cov qauv xoob los ntawm cov loj loj. Tsis tas li ntawd, pebbles yuav tsum muaj qhov chaw huv, tsis muaj cov npoo ntse, thiab cov av nkos tsawg dua lossis sib npaug li 3% txhawm rau tiv thaiv kev cuam tshuam permeability thiab compaction.
1.2 Porosity: 25% -30% rau Efficiency Balance
Porosity yog qhov tseem ceeb metric rau dej permeability, thiab cov porosity zoo ntawm pebble permeable pavement yuav tsum tau tswj ntawm 25% -30%. Hauv qhov no, txoj kev taug kev tuaj yeem nqus tau los nag sai heev (permeability npaum li cas ntau dua lossis sib npaug li 3 hli / s) kom tau raws li lub nroog cov ntaub so ntswg cov kev xav tau tam sim ntawd thaum ua kom cov qauv kev ruaj ntseg (tsis txhob muaj lub zog poob los ntawm cov porosity ntau dhau). Porosity yog kuaj los ntawm txoj kev ntim, nrog rau kev kuaj tom qab pavement txoj kev thiab ib qho kev xeem yuam kev kam rau siab Tsawg dua los yog sib npaug li 2%.
1.3 Cov Qauv Txheej Txheem Muaj Zog: Hloov rau Scenario Loads
Bearing lub zog yog txawv los ntawm cov tsheb thauj khoom:
Cov chaw taug kev (piv txwv li, cov chaw ua si hauv hnab tshos): Compressive zog Ntau tshaj los yog sib npaug rau 30MPa, flexural zog Ntau tshaj los yog sib npaug rau 3.5MPa, skid resistance (BPN) Ntau tshaj los yog sib npaug rau 60
Lub tsheb- thaj chaw hla (piv txwv li, txoj kev hauv nroog, chaw nres tsheb hauv zej zog): Compressive zog Ntau tshaj los yog sib npaug rau 40MPa, flexural zog Ntau tshaj los yog sib npaug rau 4.5MPa, skid resistance (BPN) Ntau tshaj los yog sib npaug rau 70
Raw khoom lub zog kuaj yuav tsum tau ua ua ntej- kev tsim kho, thiab rov ua cov qauv piv txwv (Ntau dua lossis sib npaug li 5% ntawm thaj chaw pavement) yog ua tom qab- kev tsim kho kom pom tseeb.
2. Scenario-Specific Design Schemes: Match Functions to Application Scenario
Pebble permeable pavement tsim yuav tsum tau ua raws li scenario functions, load yam ntxwv, thiab toj roob hauv pes xav tau kev pab los xyuas kom meej technical feasibility thiab usability.
2.1 Pocket Parks: Ecological Priority & Landscape Integration
Rau cov chaw ua si hauv hnab tshos (tseem ceeb rau kev lom zem thiab ecological zaub, nrog rau cov neeg taug kev / cov chaw me me), cov pavement tau txais cov qauv sib xyaw ntawm "pebble nto txheej (5-6cm, 5-15mm particle loj, qauv rau kev tsim kho) + nruab nrab- ntxhib xuab zeb leveling txheej (3-7d-4cm) + gravel txheej (3-4cm)-4 hli qhov muag tsis pom gravel)". 3-5m spaced drainage dig dig ditches thiab ntug grassed swals txhim khu cov dej los nag thiab purification.
2.2 Txoj Kev Hauv Nroog: Load Priority & Permeability Synergy
Rau cov ceg hauv nroog txoj kev / tsis yog- txoj kab tsheb ciav hlau (kev sib npaug permeability thiab kev nyab xeeb kev tsheb, nrog rau tsis yog- lub cev muaj zog / me me lub tsheb thauj khoom), cov qauv yog "pebble nto txheej (6-8cm, nyuaj granite pebbles, 40% 5-8mm / 40% 8-12mm / 20% 12-15mm rau kev tiv thaiv) + C25 qib, 15% -20% porosity) + graded gravel cushion (8-10cm, 5-31.5mm gravel)". A 2% -3% txoj kab nqes nqes thiab thaiv cov qhov dej kom ua kom cov dej ntws tawm sai.
2.3 Chaw nres tsheb hauv zej zog: Load Adaptation & Space Optimization
Rau cov chaw nres tsheb hauv zej zog (tsawg dua lossis sib npaug li 2.5t / qag me me tsheb thauj khoom), cov qauv sib xyaw ua ke ntawm "pebble nto txheej (5-}6cm, 5-} 12mm particle loj rau tuav, 60% kev pab) + permeable nyom-cog cib (40% kev pab them nqi, C30 qib rau ib qho sib npaug + 20mm) ntau dua stabilized txheej (15-20cm, CSB-1 qib pervious cement-stabilized gravel)" yog siv. 1-2 qhov dej qhov muag tsis pom qhov chaw nres tsheb txuas mus rau lub zej zog cov kav dej nag.
3. Cov lus qhia txog kev ua kom zoo tshaj tus nqi: Sib npaug kev lag luam thiab cov txiaj ntsig
Kev tswj tus nqi rau pebble permeable pavement khiav los ntawm tag nrho cov txheej txheem ntawm "cov khoom siv, kev tsim kho, thiab kev tsim qauv" kom txo cov nqi yam tsis muaj kev cuam tshuam zoo.
3.1 Kev Xaiv Cov Khoom Siv Hauv Zos: Txiav nqi thauj mus los
Kev thauj mus los suav rau 30% -40% ntawm cov nqi raw khoom. Xaiv qhov chaw ore hauv zos hauv 50km tuaj yeem txo cov nqi qis. Rau cov cheeb tsam uas tsis muaj pebbles, dej dredging pebbles (ntxuav thiab tshuaj xyuas rov qab siv dua) tuaj yeem txo cov nqi thiab ua tiav cov khoom siv rov ua dua tshiab, txuag kwv yees li $ 3.5 / ㎡ vs.
3.2 Cov txheej txheem tsim kho yooj yim: Txhim kho kev ua tau zoo
Txais yuav "kev tshuaj ntsuam xyuas tshuab + phau ntawv paving" kom txo cov sij hawm txheeb xyuas los ntawm 40%
Siv prefabricated pebble modules rau toj roob hauv pes scenarios (xws li, hnab tshos chaw ua si) los txhawb kev tsim kho efficiency los ntawm 30%
Hloov cov ntawv qhia qib nrog cov cuab yeej laser los txiav cov nqi rov ua haujlwm thiab txo cov nqi zog los ntawm 15% -20%
3.3 Daim ntawv thov sib xyaw nrog cov nyom-Kev cog cib: Txhim kho cov khoom sib piv
Hauv cov chaw nres tsheb hauv zej zog thiab kev taug kev hauv nroog, 5: 5 ( thaj chaw neeg taug kev) lossis 6: 4 ( thaj chaw tsheb) pebble - cov nyom cib ua ke txo cov kev siv pebble. Hauv zos pervious pob zeb nyom cib (60% -70% tus nqi ntawm pebbles) tuaj yeem txo cov nqi ntawm cov khoom siv los ntawm kwv yees li $ 2.8 / ㎡ vs. tag nrho pebble pavement, thaum cov nroj tsuag txhim kho cov txiaj ntsig ecological thiab txo cov nqi kho ntsuab.
4. Kev ntsuas qhov txiaj ntsig: Ua kom tiav qhov project tus nqi
Pebble permeable pavement muab ntau yam txiaj ntsig hauv kev txuag dej, kev txo qis hauv dej, thiab kev saib xyuas, nrog rau qhov muaj nuj nqis los txhawb qhov kev txiav txim siab ua haujlwm - ua.
4.1 Kev txuag dej txhua xyoo: Kev siv dej los nag zoo
Pebble permeable pavement sau cov dej nag rau cov dej ntsuab thiab kev tu txoj kev. Kev soj ntsuam cov ntaub ntawv los ntawm North Tuam Tshoj txoj haujlwm hauv zej zog qhia tau hais tias 1500m³ / 10,000㎡ txhua xyoo kev sau dej nag (sib npaug rau 35%-40% dej txuag vs. kev ua haujlwm nyuaj), tsim tau $ 1,800 / 10,000㎡ txhua xyoo kev txuag dej (raws li $ 1 / m³ kais dej nqi).
4.2 Waterlogging Mitigation: Txo cov dej ntws tawm
Hauv cov nag hnyav (50mm / h dej nag), pebble permeable pavement txo cov dej ntws los ntawm 75% (khiav coefficient=0.2 vs. 0.8 rau cov asphalt pavement), tshem tawm cov dej tsub zuj zuj thiab cuam tshuam kev tsheb khiav qeeb thiab cov chaw puas tsuaj los ntawm kwv yees li $ 1,100 / 10,000㎡ ib xyoos ib zaug (cov ntaub ntawv ib xyoos ib xyoos).
4.3 40% Cov Nqi Them Nqi Them Nqi: Ntxiv cov txiaj ntsig ntawm lub neej
Pebble pavement lub durability thiab tiv thaiv-clogging zog txo cov nqi kho txhua xyoo rau $1/㎡ vs. $1.7/㎡ rau cov tsoos asphalt pavement (a 41.7% txo, ze rau 40% lub hom phiaj). Kev saib xyuas muaj feem xyuam rau peb lub hlis twg siab - ntxuav lub siab thiab tu cov khib nyiab tsis tu ncua, nrog rau 15 xyoo kev txuag nyiaj ntawm $10.5/㎡ vs.
Xaus
Pebble permeable pavement muaj qhov zoo tshaj plaws kev lag luam thiab kev lag luam hauv sponge nroog kev tsim kho, kev sib koom ua ke ntawm ecological, kev lag luam, thiab kev sib raug zoo los ntawm kev tswj xyuas kev tshawb fawb, scenario-tshwj xeeb tsim, thiab tag nrho- kev ua kom zoo dua qub. Cov neeg tsim qauv hauv nroog yuav tsum ua qhov tseem ceeb ntawm qhov tsis sib xws- qhov xwm txheej sib piv, cov tsev tsim kho yuav tsum muaj kev tswj xyuas kom zoo, thiab cov tsev saib xyuas vaj tse tuaj yeem txhawb nqa nws raws li qhov xav tau ntawm lub nroog daim txhuam cev. Nrog rau kev nce qib ntawm cov khoom siv thiab kev tsim kho thev naus laus zis, pebble permeable pavement yuav ua lub luag haujlwm tseem ceeb dua hauv kev tsim eco- cov phooj ywg daim txhuam cev hauv nroog.
