1. Cov txiaj ntsig tseem ceeb ntawm pob zeb hauv qhov qis-Cov nqi toj roob hauv pes
Tus nqi tseem ceeb tshaj qhov zoo, txo tag nrho qhov project peev: Nyob rau hauv cov nqe lus ntawm kev yuav khoom, tus nqi lag luam ntawm ntujpob zebtsuas yog 1/3 mus rau 1/5 ntawm cov vuas granite pem teb, thiab cov nqi tsheb thauj mus los qis dua (tsis xav tau ntim tshwj xeeb tiv thaiv); nyob rau hauv cov nqe lus ntawm kev tsim kho tus nqi, gravel nteg tsis xav tau cov kws tshaj lij cov neeg ua haujlwm thiab tuaj yeem ua tiav los ntawm pab pawg tsim kho zoo tib yam, txo cov nqi zog ntau dua 40%. Noj 100㎡ toj roob hauv pes hauv av ua piv txwv, tus nqi them (cov khoom siv + kev ua haujlwm) ntawm cov gravel tov feem ntau yog tswj ntawm 3,000-5,000 yuan, uas yog qis dua li ntawm 10,000-15,000 yuan ntawm tsoos paving, zoo heev txo qhov project pob nyiaj siab.
Kev tsim kho yooj yim thiab nrawm, luv luv siv sijhawm: Gravel nteg tsis xav tau kev kho mob yooj yim (xws li pob zeb leveling, mortar bonding). Nws tsuas yog yuav tsum tau yooj yim theem hauv av thiab nteg cov nroj tsuag -cov ntaub ntawv pov thawj ua ntej kis pob zeb. Ib cheeb tsam 100㎡ tuaj yeem ua tiav hauv 1-2 hnub. Rau cov phiaj xwm ib ntus nrog lub sijhawm nruj (xws li qhov chaw teeb tsa ua ntej kev nthuav qhia) lossis kev hloov pauv toj roob hauv pes loj, pob zeb tuaj yeem ua rau lub sijhawm tsim kho, txo qhov cuam tshuam ntawm kev tsim kho ntawm qhov chaw siv, thiab tib lub sijhawm txo cov nqi ntxiv los ntawm kev tsim kho qeeb.
Reusable, Conforming rau Sustainable Concepts: Pob zeb muaj zog durability thiab saj zawg zog nteg txoj kev. Tom qab qhov project tiav lawm, nws tuaj yeem khaws cia yooj yim thiab rov siv dua hauv lwm qhov chaw toj roob hauv pes (xws li hloov chaw hauv tsev, ntxiv cov pob zeb poob hauv lwm qhov chaw). Qhov no recyclable feature tsis tsuas yog txo cov tiam ntawm kev tsim pov tseg, tab sis kuj tseem txo cov khoom siv tus nqi ntawm cov haujlwm tom ntej, ua raws li lub tswv yim ntawm kev tsim kho vaj tse ntsuab ntsuab.
2. Muaj peev xwm tsis zoo ntawm Gravel Application
Kev siv tsis zoo, txwv tsis pub siv cov xwm txheej: Muaj qhov sib txawv ntawm gravel particles, thiab saum npoo muaj qee yam fluidity. Lub rooj zaum lub log yog ib qho yooj yim kom tau daig hauv qhov sib txawv ntawm qhov sib txawv, ua rau nws tsis yooj yim kom dhau mus. Strollers tseem yuav muaj kev sib tsoo thiab lub log thaum thawb. Qhov kev tsis zoo no ua rau nws nyuaj rau siv rau cov cheeb tsam uas yuav tsum tau ua kom yooj yim rau kev khiav tsheb, xws li cov tsev laus, cov chaw ua si rau menyuam yaus, thiab kev txwv tsis pub- cov ntawv pub dawb, txwv tsis pub muaj kev pab them nqi kho mob ntawm thaj chaw ua haujlwm.
Nyuaj daus ntxuav hauv lub caij ntuj no, cuam tshuam rau cov neeg siv kev paub: Tom qab daus poob rau lub caij ntuj no, cov daus ntawm cov pob zeb saum npoo yog qhov nyuaj rau kev ntxuav kom huv los ntawm cov khoom siv shoveling ib txwm muaj - lub shovel yog ib qho yooj yim rau shovel li pob zeb thiab daus ua ke, ua rau hauv av tsis sib xws; Yog tias siv cov tshuaj deicing, tshuaj lom neeg tuaj yeem ua raws li cov gravel nto, uas tsis tsuas yog cuam tshuam rau cov toj roob hauv pes zoo nkauj, tab sis kuj tseem tuaj yeem nkag mus rau hauv av nrog dej nag thiab cuam tshuam rau kev loj hlob ntawm cov nroj tsuag, ua rau muaj kev nyuaj rau lub caij ntuj no kev saib xyuas toj roob hauv pes.
Yooj yim kom tsis sib xws tom qab ntev -Tsev siv sijhawm, Yuav tsum tau saib xyuas ntau zaus: Kev cuam tshuam los ntawm cov xwm txheej xws li dej nag scouring thiab tib neeg trampling, gravel yog nquag mus rau hauv zos tsub zuj zuj los yog poob, uas ua rau tsis sib xws phenomena xws li kev nyuaj siab thiab protrusions nyob rau hauv av. Especially in areas with dense pedestrian flow, the flatness of the ground decreases significantly after long-term use, which not only affects walking comfort but also may increase the safety risk of pedestrians tripping, requiring additional manpower for leveling and maintenance.
3. Lub hom phiaj kev txhim kho txoj kev tsis zoo ntawm daim ntawv thov gravel
"Gravel + Stepping Stone" Kev sib xyaw ua ke, txhim kho kev ua haujlwm zoo: Txais tus qauv tsim ntawm "gravel as the base + stepping stones nted at intervals" on the main traffic paths (xws li lub tshav puam, kev ua si hauv cheeb tsam). Cov kauj ruam pob zeb yog tiv thaiv - pob zeb slabs ntawm 30cm × 60cm, thiab qhov sib nrug yog tswj ntawm 30-40cm (nyob rau hauv txoj kab nrog ib txwm stride). Qhov kev daws teeb meem no tsis tsuas yog khaws cov nqi qis thiab kev ntxhib los mos ntawm cov pob zeb tab sis kuj daws cov teeb meem kev tsheb khiav ntawm lub rooj zaum muaj log thiab cov tsheb kauj vab los ntawm cov kauj ruam pob zeb, ntsuas kev lag luam thiab kev ua haujlwm.
Tso GeoTextile los txhim kho Base Stability: Ua ntej nteg gravel, thawj nteg GeoTextile (tseem hu ua geotextile) ntawm lub hauv paus. GeoTextile muaj cov yam ntxwv ntawm lub zog siab thiab kev tiv thaiv corrosion, uas tuaj yeem txhim kho txoj haujlwm ntawm pob zeb thiab txo cov khoom poob los ntawm cov dej los nag; Nyob rau tib lub sijhawm, nws cov huab cua -permeable thiab av- cov yam ntxwv impermeable tuaj yeem cuam tshuam cov nroj tsuag kev loj hlob, txo qhov zaus ntawm kev saib xyuas tom qab, thiab txhim kho qhov teeb meem ntawm qhov yooj yim unevenness ntawm gravel av.
Tsis tu ncua Raking Maintenance kom lub hauv av tiaj tus: Tsim ib txoj kev npaj tu ncua, thiab siv ib qho tshwj xeeb gravel rake nrog ib tug hniav pitch ntawm 10-15cm mus rau theem hauv av txhua 1-2 lub hlis, dispersing cov pob zeb sau mus rau qhov chaw sunken; for areas with dense pedestrian flow, the maintenance frequency can be appropriately increased (such as once a month). Yog tias muaj kev tso cai, cov khoom siv hluav taws xob me me tuaj yeem tsim kho kom zoo dua qub thiab xyuas kom meej tias cov av gravel nyob twj ywm rau lub sijhawm ntev, txhim kho kev nplij siab ntawm kev siv.
Ntug Kho Kho Kho Kom Tiv Thaiv Gravel Diffusion: Txais kev kho ntug kev ntsuas ntawm ntug ntawm pob zeb- thaj chaw pav (xws li kev sib tshuam nrog cov nyom thiab txoj kev) - 5-8cm siab tiv thaiv -corrosion ntoo thav duab, hlau strips, los yog cov pob zeb ruaj khov siv tau, kos 3-5cm hauv qab hauv av los tsim ib qho kev thaiv lub cev. Txoj kev kho no tuaj yeem tiv thaiv pob zeb kom tsis txhob kis mus rau thaj tsam ib puag ncig vim kev trampling thiab dej nag scouring, zam qhov teeb meem ntawm kev txo qis hauv av thiab muaj kuab paug ntawm thaj chaw ib puag ncig los ntawm pob zeb, thiab tswj kev huv ntawm toj roob hauv pes.
