Precast lub thawv citts muab ib qho kev ntseeg siab thiab muaj txiaj ntsig zoo rau kev ua yeeb yam tsooske {{} {1} {qhov chaw. Lawv tau tsim los muab ruaj thiab ntev -} kav cov kev daws teeb meem rau ntau yam txheej txheem txheej txheem. Ntawm no yog ib qho qhia qhia dav rau cov txheej txheem teeb tsa ntawm lub thawv teeb hluav taws xob:
- Txoj kev tsim qauv
1. Qhov Chaw Npaj
Kev Ntsuas thiab Kev Teeb Meem: Pib nrog kev ntsuas raug thiab kev sib tw kom ntseeg tau tias tus culvert yog muab rau kom raug. Qhov no cuam tshuam nrog kev kos cim nruab nrab ntawm nruab nrab thiab kev ua haujlwm ntawm tus culvert.
Kev khawb: kos lub trench rau qhov yuav tsum tau tob thiab dav. Nco ntsoov cov trench yog ruaj khov thiab pub dawb los ntawm dej los yog khib nyiab.
Kev npaj subgrade: Npaj cov subgrade los ntawm kev sib txuas cov av rau qhov yuav tsum tau ntom. Qhov no ua kom ntseeg tau lub hauv paus ruaj khov rau cov culvert.
2. Lub hauv paus ua haujlwm
Pob zeb ua ke: ncuav lub hauv paus ua ke los muab cov ruaj khov thiab qib saum npoo rau cov culvert. Lub hauv paus no yuav tsum tau tsim los txhawb qhov hnyav ntawm tus culvert thiab cov tsheb thauj khoom.
Qhov Cuab Zog: txhim kho lub zog lub ntsiab ua raws li tau teev tseg hauv kev tsim. Cov kauj ruam no yog qhov tseem ceeb rau cov qauv txheej txheem ntawm tus culvert.
3. Culvert installation
Lifting thiab kev kawm: Siv cranes lossis lwm yam khoom nqa los tso cov thawv precast Culvert rau hauv cov trench. Xyuas kom cov ntu tsis sib xws thiab qib.
GROUTING: Thov cov zaub mov ntawm cov ntu kom ntseeg tau tias lub foob ntim dej. Cov kauj ruam no yog qhov tseem ceeb rau kev tiv thaiv dej infiltration thiab ua kom muaj kev ua kom ntev ntawm lub culvert.
4. Backfilling
Symmetrical Backfilling: Cov tog sab qab ntawm lub culvertically kom tiv thaiv tsis ncaj ntawm cov qauv. Siv zoo - compacted av lossis engineered sau cov khoom.
Kev sib koom ua ke: ua kom cov khoom siv hluav taws xob tau muab khi ua ke los muab kev txhawb nqa txaus thiab tiv thaiv kev sib haum xeeb.
- Kev Siv Ua
1.Txoj kev ntsuas thiab cov txheej txheem: qhov tseeb thiab kev ntsuas yog qhov tseem ceeb rau kev ua kom tsim nyog.
2.Txhua: Khawb cov trench rau qhov uas yuav tsum tau ua, ua kom muaj kev ruaj khov thiab kev nyab xeeb.
3. Tam sim no kev soj ntsuam: Kev coj ua load {{- Cov kev ntsuam xyuas cov kabmob kom ntseeg tau tias tus culvert.
4.Foundation ua haujlwm: ncuav lub hauv paus thiab kev txhawb nqa lub zog uas tau hais tseg.
5.Rebar Installation: khi lub zog lub ntsiab rau lub hauv paus thiab Culvert lub cev.
6.Template teeb: nruab cov tub sab sab hauv thiab sab nraud rau cov ntu CULVER.
7.Txoj kev ua raws li: ncuav cov qhob ua nyob rau theem, pib nrog lub hauv paus slab thiab tom qab ntawd sab phab ntsa.
8.Qhov chaw thiab qauv rau sab qaum: khi lub zog thiab teem cov qauv rau cov ntu sab saud.
9.Pepper nrug Pouring: ncuav seem qaum ntawm sab phab ntsa thiab sab saum toj slab.
10.Formwork Tshem Tawm: Tshem tawm cov formwork thaum cov qhob tau mus txog qhov yuav tsum muaj zog.
11.Backfilling: Cov thaub qab ntawm lub pob txha ntawm culvertically, kom paub meej cov kab ke raug.
12.Muaj thiab qhov hluav taws xob tsim tawm: tsim cov inlet thiab qhov hluav taws xob, suav nrog ib qho kev ua haujlwm masonry.
13.Sealing thiab waterproofing: Foob cov pob qij txha thiab thov cov kev kho mob dej rau sab nrauv ntawm cov culvert.
14.Txhais Backfilling: Ua tiav cov txheej txheem tom qab, ua kom thaj chaw tau raug ua kom zoo thiab tau qhab nia.
Precast Box Culverts muaj qhov tseem ceeb ntawm cov ntsiab lus ntawm kev ua kom ruaj khov, nrawm ntawm kev teeb tsa, thiab yooj yim ntawm kev saib xyuas. Cov txheej txheem kev teeb tsa yuav tsum npaj ua tib zoo npaj thiab ua tiav los xyuas kom cov culvert ua raws li tsim. Ntawm Fujian Unik Pwm Technology Co., Ltd. Txuas mus xyuas www.unikmould.com los tshawb txog peb lub thawv precast culvert pwm thiab nrhiav seb lawv tuaj yeem txhim kho koj cov haujlwm tsim kho.
