Curb pob zeb txheej txheem txheej txheem
Curb stone yog hais txog lub pob zeb ciam teb nyob rau ntawm ntug kev, hu ua curb. Nws yog siv los ua ib lub pob zeb teeb nyob rau ntawm ciam teb ntawm ntug ntawm txoj kev nto thiab lwm yam kev siv txoj siv sia. Nws ua lub luag haujlwm hauv kev ua kom muaj kev nyab xeeb ntawm cov neeg taug kev, tsheb khiav tsheb thiab ua kom muaj kev zoo nkauj ntawm txoj kev. Nyob rau tib lub sijhawm, nws ua lub luag haujlwm los pab tshem tawm cov dej ntawm txoj kev.
Cov curbs feem ntau muaj xws li: sawv curbs (sab pob zeb), tiaj curbs (cov pob zeb tiaj tus), tshwj xeeb curbs (nrog rau txoj kev nkhaus curbs, cais txoj siv curbs, reflective curbs, deceleration curbs), thiab lwm yam.
Curbspob zeb kev tsim khotxujci yam ntxwv
Txoj kev tsim kho no ua rau kev txhim kho kev txhim kho thiab tuaj yeem tsim cov txiaj ntsig kev lag luam ntau dua los ntawm kev ua kom zoo dua qhov ncaj thiab ruaj khov ntawm kev thaiv thiab lub zog compressive ntawm cov pob zeb.
01 ib. Kev tsim kho txheej txheem thiab cov ntsiab lus ua haujlwm
1. txheej txheem ntws
Curb prefabrication → tsheb thauj mus los → kev tsim kho lofting → curb cushion pouring → curbstone installation → backrest pouring → kev noj qab haus huv
2. Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm
1. Kev soj ntsuam thiab teeb tsa:
Tom qab kuaj xyuas tias txoj kab nruab nrab yog qhov tseeb, ntsuas qhov ciam teb ntawm txoj kev taug kev nyob rau hauv lem, teem tawm txoj kab ntawm txoj kev, thiab teem caij rau sab pawg tswj kev taw qhia thiab qhov siab. Cov kab kev tsim kho tuaj yeem rub tawm ntawm pawg sab nrauv thiab sab pawg hauv qhov ncaj, thiab qhov sib nrug ntawm pawg yog 10m; Raws li lub vojvoog tsim, sab pawg yuav tsum tau densified nyob rau hauv nkhaus nkhaus thiab kev sib tshuam seem, nrog pawg sib nrug ntawm 5m thiab kev sib tshuam pawg sib nrug ntawm 1 ~ 5m, thiaj li yuav xyuas kom meej qhov loj ntawm nkhaus arc. Tag nrho cov chaw nres tsheb, theodolite thiab qib yuav tsum tau siv rau kev teeb tsa.
2. Nruas installation:
Tom qab lub nailing pawg yog dai, curbs yuav tsum tau teem ib sab ntawm lub hauv paus nyob rau hauv lem. Ua ntej txhim kho lub kerb, lub formwork yuav tsum tau mounted thiab 100 hli tuab C15 pob zeb cushion yuav tsum tau poured, thiab ces lub 1: 2 mortar yuav tsum tau tov rau hauv qab. Lub mortar thickness yuav tsum yog 30mm. Lub curb yuav tsum tau ntsia raws li qhov chaw tawm.
Xam cov pob zeb thaiv hauv txhua ntu ntawm kev sib tshuam ua ntej. Thaum lub tsev tsim, ntu txoj kev yog muab tso rau ntawm qhov chaw txiav ntawm ib sab ntawm kev sib tshuam mus rau lwm qhov ntawm kev sib tshuam hauv lub sijhawm luv luv; thaum txoj kev ntu ntev, nws tau ua tiav los ntawm nruab nrab mus rau ob qhov kawg kom txuas nrog qhov tsis sib xws ntawm kev sib tshuam.
Qhov kev hloov kho qhov thaiv yuav tsum tau muab txiav thiab tsim los yog ua los ntawm cam khwb cia-hauv-situ pob zeb ntawm tib theem zog. Kev hloov kho qhov thaiv yuav tsum tsis txhob ua los ntawm bricking thiab plastering. Lub pob zeb thaiv ntawm lub gully yuav tsum tau tsim ua ke nrog lub gully, thiab qhov sib txawv ntawm cov curbs nyob ib sab yuav tsum siv 8 hli tuab hlau los yog yas board tswj, qhov sib txawv ntawm cov curbs nyob ib sab yuav tsum zoo ib yam.
Tom qab kev teeb tsa, txoj kab yuav tsum tau dai dua, thiab qhov curb yuav tsum tau kho kom ncaj, du thiab theem, thiab lub dav hlau thiab qhov siab ntawm qhov curb yuav tsum raug kuaj pom. Thaum lub dav hlau thiab qhov siab siab tshaj tus qauv, kev hloov kho yuav tsum tau ua. Barrier-free curbs yuav tsum tau ntsia raws li kev tsim qauv. Tom qab kev teeb tsa tau tsim nyog, C15 pob zeb yuav tsum tau siv rau rov qab nchuav thiab cov cement mortar sib koom ua ke nyob rau lub sijhawm kom ntseeg tau tias kev ruaj ntseg ntawm kev thaiv. Siv txoj kev ntub dej kom muaj kev noj qab haus huv rau 3 hnub, thaum lub sij hawm kev sib tsoo yuav tsum tiv thaiv.
3. Cov kev cai yooj yim rau kev thaiv kev teeb tsa:
Cov pob zeb curb yuav tsum ruaj khov, thiab cov kab yuav tsum ncaj thiab du, qhov saum npoo yuav tsum huv thiab tsis muaj kuab paug, thiab cov pob zeb ntawm cov pob zeb curb yuav tsum nruj. Lub zog compressive ntawm curb pob zeb ua tau raws li cov qauv tsim.
02. Cov khoom siv thiab khoom siv
1. Cov khoom siv
Cov ntaub ntawv xav tau rau curb:
Txoj kev thaiv yog ua los ntawm C30 pob zeb, thiab cov pob zeb ua kom muaj zog yuav tsum ua tau raws li qhov yuav tsum tau ua. Nws yuav tsum muaj cov xim sib xws, tsis muaj qhov tawg ntawm qhov chaw, ua tiav cov npoo thiab cov ces kaum, zoo ib yam, tsis muaj qhov pom tseeb thiab xim sib txawv. Nws tsis raug tso cai kom poob, tsoo, tsoo lossis pob thaum thauj khoom thiab tshem tawm kom tsis txhob muaj kev puas tsuaj.
03. Kev ntsuas kev nyab xeeb
1. Ua ntej pib kev tsim kho, ua kom muaj kev nyab xeeb kev tsim khoom rau txhua tus neeg ua haujlwm, thiab cov neeg ua haujlwm kev nyab xeeb ua kev tshuaj xyuas kev tsim kho;
2. Cov neeg ua haujlwm kho tshuab yuav tsum nruj me ntsis raws li cov txheej txheem kev khiav hauj lwm kom muaj kev nyab xeeb ntawm ntau yam khoom siv thiab tsheb;
3. Ua haujlwm zoo hauv kev tuav pov hwm kev ua haujlwm, ua tiav cov ntawv pov hwm kev ua haujlwm, thiab ua kom muaj kev nyab xeeb ntawm tus kheej ntawm cov neeg ua haujlwm;
4. Txheeb xyuas lub sijhawm kom tshem tawm cov kev phom sij zais cia thiab tiv thaiv lawv ua ntej lawv tshwm sim;
5. Kev tiv thaiv ib ntus yuav tsum ua ke nrog kev tiv thaiv mus tas li.
04. Kev tiv thaiv ib puag ncig
1. Ua tib zoo ua raws li kev cai lij choj thiab kev tiv thaiv ib puag ncig hauv tebchaws, ua tib zoo saib xyuas kev tiv thaiv ib puag ncig ecological hauv cheeb tsam kev tsim kho raws kab, thiab txo cov pa phem ib puag ncig.
2. Rau cov neeg ua haujlwm tsim kho, yuav tsum muaj kev tiv thaiv zoo thaum ua haujlwm ntawm cov chaw uas muaj suab nrov.
3. Kev ntsuas yuav tsum tau coj los tswj cov plua plav thiab txo cov khoom pov tseg thaum lub sij hawm tsim kho.
4. Teeb lub cev lub cev ntawm qhov chaw tsim kho, thiab tsis muaj cov khoom siv yuav tsum tau muab tso rau sab nraum lub thawv.
05. Kev Ntsuam Xyuas Nyiaj Txiag
Kev txheeb xyuas nyiaj txiag
1. Txoj kev tsim kho no tuaj yeem txhim kho qhov zoo, txo tus nqi thiab ua kom nrawm ntawm kev tsim kho los ntawm kev ua kom zoo dua cov cuab yeej siv tsim nyog thiab kev tsim kho.
2. Kev tshuaj xyuas txog kev noj qab haus huv thiab ib puag ncig
3. Txoj kev tsim kho no tau tsim cov txheej txheem kev tsim kho dav dav los ntawm kev tshawb fawb ntawm cov txheej txheem kev tsim kho, kev tsim kho tshuab thiab lwm yam teeb meem, uas txhim kho qhov zoo ntawm qhov project, shortens lub sij hawm tsim kho, txuag cov peev txheej, thiab txo tus nqi. Nws muaj txiaj ntsig zoo rau kev sib raug zoo thiab ib puag ncig.
