Kumanga msewu wozizira wa asphalt

Gawani:
Kumanga msewu wozizira wa asphalt ndi projekiti yokhala ndi masitepe angapo ndi mfundo zazikulu. Zotsatirazi ndikulongosola mwatsatanetsatane za ntchito yomanga:
I. Kukonzekera zinthu
Kusankha kwa zinthu zozizira za asphalt: Sankhani zinthu zozizira za asphalt molingana ndi kuwonongeka kwa msewu, kuyenda kwa magalimoto ndi nyengo. Zida zapamwamba zozizira zozizira ziyenera kukhala zomatira bwino, kukana madzi, kukana nyengo ndi mphamvu zokwanira kuti zitsimikizire kuti msewu wokonzedwa umatha kupirira katundu wa galimoto ndi kusintha kwa chilengedwe.
Kukonzekera kwa zida zothandizira: Konzani zida zoyeretsera (monga matsache, zowumitsira tsitsi), zida zodulira (monga zodulira), zida zophatikizira (monga ma tampers amanja kapena magetsi, odzigudubuza, malinga ndi malo okonzera), zida zoyezera (monga tepi miyeso ), zolembera zolembera ndi zida zotetezera chitetezo (monga zipewa zotetezera, zovala zowonetsera, magolovesi, ndi zina zotero).
II. Masitepe omanga
(1). Kafukufuku wapamalo ndi chithandizo choyambira:
1. Unikani malo omangawo, mvetsetsani mtunda, nyengo ndi mikhalidwe ina, ndi kupanga pulani yoyenera yomangira.
2. Chotsani zinyalala, fumbi, ndi zina zotero pamwamba pa maziko kuti muwonetsetse kuti mazikowo ndi owuma, oyera komanso opanda mafuta.
(2). Dziwani komwe kudakumba dzenje ndikutsuka zinyalala:
1. Dziwani malo okumba dzenje ndi mphero kapena kudula malo ozungulira.
2. Tsukani miyala ndi zinyalala zotsalira mkati ndi mozungulira dzenjelo kuti zikonzedwenso mpaka malo olimba awonekere. Panthawi imodzimodziyo, sikuyenera kukhala zinyalala monga matope ndi madzi oundana m'dzenjemo.
Mfundo ya "kukonza maenje ozungulira maenje ozungulira, kukonza molunjika kwa maenje okhotakhota, komanso kukonza maenje ophatikizika" ayenera kutsatiridwa pokumba dzenjelo kuonetsetsa kuti dzenje lokonzedwanso lili ndi m'mphepete mwaukhondo kuti mupewe kutayikira komanso kuluma m'mphepete chifukwa cha dzenje losagwirizana. m'mphepete.

(3). Ikani choyambira:
Ikani zoyambira pamalo owonongeka kuti muwonjezere kumamatira pakati pa chigamba ndi msewu.
(4). Falitsa chigamba chozizira:
Malinga ndi kapangidwe amafuna, wogawana kufalitsa phula ozizira chigamba zakuthupi kuonetsetsa makulidwe yunifolomu.
Ngati kuya kwa dzenje la msewu ndi lalikulu kuposa 5cm, liyenera kudzazidwa ndi zigawo ndi kuphatikizika wosanjikiza ndi wosanjikiza, ndi gawo lililonse la 3 ~ 5cm kukhala loyenera.
Pambuyo podzaza, pakati pa dzenjelo liyenera kukhala lalitali pang'ono kuposa msewu wozungulira komanso mawonekedwe a arc kuti ateteze mano. Pakukonza misewu yamatauni, kuyika kwa zida zozizira kumatha kuonjezedwa ndi 10% kapena 20%.
(5). Chithandizo cha compaction:
1. Malingana ndi chilengedwe chenichenicho, kukula ndi kuya kwa malo okonzerako, sankhani zida zoyenera zogwirizanitsa ndi njira zopangira.
2. Kwa maenje okulirapo, ma wheel wheel roller kapena ma vibrating rollers angagwiritsidwe ntchito pophatikizana; kwa maenje ang'onoang'ono, kupopera kwachitsulo kungagwiritsidwe ntchito pophatikizana.
3. Pambuyo pophatikizana, malo okonzedwawo ayenera kukhala osalala, ophwanyika, komanso opanda magudumu. Malo ozungulira ndi ngodya za maenjewo ayenera kukhala osakanikirana komanso opanda kutayirira. Digiri yophatikizika ya kukonzanso misewu wamba ikuyenera kupitilira 93%, ndipo kuchuluka kwa kukonzanso misewu kuyenera kupitilira 95%.
(6_. Kusamalira madzi:
Malinga ndi nyengo ndi zinthu zakuthupi, madzi amawapopera moyenera kuti asamalire kuonetsetsa kuti chigamba chozizira cha asphalt chili cholimba.
(7_. Kukonza mosasunthika ndikutsegula kwa magalimoto:
1. Pambuyo pa kuphatikizika, malo okonzera amafunika kusungidwa kwa nthawi. Nthawi zambiri, mutagubuduza kawiri kapena katatu ndikuyimirira kwa ola limodzi kapena awiri, oyenda pansi amatha kudutsa. Magalimoto amatha kuloledwa kuyendetsa motengera kulimba kwa msewu.
2. Pambuyo pokonzanso malo atsegulidwa kwa magalimoto, zida zozizira za asphalt zidzapitirizabe kupangidwa. Pambuyo pa nthawi ya magalimoto, malo okonzekera adzakhala pamtunda wofanana ndi msewu woyambirira.
3. Njira zodzitetezera
1. Chikoka cha kutentha: Zotsatira za zipangizo zozizira zozizira zimakhudzidwa kwambiri ndi kutentha. Yesetsani kumanga nthawi yotentha kwambiri kuti mupititse patsogolo kaphatikizidwe ndi kuphatikizika kwa zida. Pomanga m'malo otsika kutentha, njira zotenthetsera zisanachitike, monga kugwiritsa ntchito mfuti yotentha kuti itenthetse maenje ndi zida zoziziritsa kuzizira.
2. Kuwongolera chinyezi: Onetsetsani kuti malo okonzerawo ndi owuma komanso opanda madzi kuti musakhudze kumamatira kwa zipangizo zozizira zozizira. Pamasiku amvula kapena chinyezi chikachuluka, ntchito yomanga iyenera kuyimitsidwa kapena njira zotetezera mvula ziyenera kuchitidwa.
3. Chitetezo cha chitetezo: Ogwira ntchito yomanga ayenera kuvala zida zotetezera chitetezo ndikutsata njira zoyendetsera chitetezo kuti atsimikizire chitetezo cha zomangamanga. Panthawi imodzimodziyo, tcherani khutu ku chitetezo cha chilengedwe kuti mupewe kuipitsa malo ozungulira ndi zinyalala zomanga.
4. Kusamalira pambuyo
Kukonzekera kukatha, fufuzani nthawi zonse ndikusunga malo okonzerako kuti muwone mwamsanga ndi kuthana ndi zowonongeka zatsopano kapena ming'alu. Pazovala zazing'ono kapena kukalamba, njira zokonzetsera zapanyumba zitha kuchitidwa; pakuwonongeka kwadera lalikulu, kukonzanso kukonzanso kumafunika. Kuonjezera apo, kulimbikitsa ntchito yokonza misewu tsiku ndi tsiku, monga kuyeretsa nthawi zonse ndi kukonza kayendedwe ka madzi, kungathe kuwonjezera moyo wautumiki wamsewu ndikuchepetsa kukonzanso pafupipafupi.
Mwachidule, ntchito yomanga msewu wozizira wa asphalt iyenera kutsatira mosamalitsa njira zomangira ndi kusamala kuti zitsimikizire kuti ntchito yomangayo ndi yabwino. Panthawi imodzimodziyo, kukonzanso pambuyo pake ndi gawo lofunika kwambiri loonetsetsa kuti moyo wautumiki wamsewu ndi chitetezo choyendetsa galimoto.
