Ndeapi Mhando dzeMidziyo yeKuvaka yeMigwagwa Inonyatsosimudzira Kumhanya kweProjekiti uye Kuderedza Mari?

Wakambozvibvunza here kuti sei mapurojekiti emigwagwa achinonoka kunyangwe paine simbi yakawanda kudaro?

Kana ukapfuura nebasa remumugwagwa ukaona michina yakawanda yero yakamira yakanyarara, ungangozvibvunza kuti, “Nemhando dzese idzodzo dzemidziyo yekuvaka yemigwagwa, sei pasina chimwe chinhu chinofamba nekukurumidza?” Mhinduro haisi simba remabhiza; kuziva kuti ndechipi chishandiso chekushandisa, rini, uye sei. Pasi apa tinoparura mhando dzese huru dzemidziyo yekuvaka migwagwa, zvainoita chaizvo, uye nzira dzekunyepedzera dzazvinochengetedza—kana kuti zvinopisa—mari.

Vatatu Vanofamba Nenyika: Mabhurudhoza, Mabhuroka, uye Muchina weMota Usina Kuongororwa

Mabulldozer anotanga zvinhu nekukweva nekusundira ivhu repamusoro kubva munzira. Pamabasa mazhinji ekuNorth America vanochinja 90–120 m³ paawa, asi matangi iwayo anoverengwa kana mushandi akakanganwa kutsveyamisa banga kuti awane ivhu rinonamira. Tevere, ma scrapers anozvitakura nekutakura zvinhu zviri kure nemakiromita maviri—chero chinhu chiri kure uye marori ekurasira marara anoba chiratidziro. Bhiza rerima pano ndiro injini yekuisa mota. Mapepa emhando yepamusoro anozvirumbidza ne200 hp, asi kukosha kwaro chaiko ndiko kunyatsoshanda kwelaser kunoita kuti giredhi rekupedzisira rirambe riri mukati me10 mm. Kana usina spec iyoyo uchadurura imwe 50 mm yeasphalt kuti "inyatsonaka." Izvo zvinodhura $13 k pamakiromita emugwagwa, ouch!

Midziyo Yokumanikidza: Sheepsfoot, Pneumatic, kana Smooth Drum—Ndiani Anokunda?

Mushure mekunge ma "earth movers" aenda, kudzvanywa kunosarudza kana mugwagwa wako ukagara kwemakore gumi kana makumi maviri. Ma "sheepsfoot rollers" anokanya ivhu rakapfuma munyoro, achidzvanya mhepo isina chinhu pasi pe12%. Zvigadziko zve "granular" zvinovenga mahwanda iwayo; zvinoda "kneading-plus-impact combo" yema "pneumatic-tired rabber-tired" ma "rollers". Panguva iyi, ma "drum-tired vibratory compactors" anopedzisa pamusoro pe150 mm ye "aggregate base" ne frequency inosvika 28–32 Hz—yakakwirira zvakakwana kuti ivhu rivhurike mahwindo ari pedyo, akaderera zvakakwana kudzivirira kupwanyika kwematombo. Chinjana chero cheaya ma "rollers" uye uchava ne "density" shoma kana kuti "over-compact", zvese izvi zvinotungamira pakupwanyika nekukurumidza.

Kugaya, Kugadzira Pave, uye Hupenyu Hwakavanzika hweScreeds

Asphalt itsva isati yaonekwa, maplane anotonhora anotsenga pamusoro pekare nespeed inosvika 100 m paminiti. Vashandi vanoti "milling," uye space space yedhiramu ndiyo inosarudza kana uchisiya magadzirirwo akanaka kana kuti tsvina yebhodhi rekugezesa. Screed yepaver inobva yarova mat itsva pahukobvu hwayo. Mapave emhando yepamusoro emazuva ano anoshandisa sonic sensors kuchengetedza kusiyana kwehukobvu pasi pe3 mm—diki, asi milimita yega yega yakaenzana ne12 kg yemusanganiswa pa square metre. Pabasa remakiromita gumi, remigwagwa miviri iro 3 mm error inowedzera kuita 240 t yeasphalt, inenge $18 k yezvinhu. Saka hongu, screed yacho inyaya huru.

Vatsigiri Vanoponesa Zuva: Mavhiri Anotakurisa, MaCompactor, uye MaLight Towers

Michina yekutakurisa mavhiri inounganidza zvinhu zvakawanda uye inodyisa fekitari yeasphalt; bhaketi re3-m³ rinogona kutenderera ka140 paawa kana chivanze chakamira. Wedzera chinotenderera chinotenderedza midziyo pamucheto wemidziyo uye uchaderedza kutsvedza kwevhiri remutakurisa ne8%, uchichengetedza marita angangoita gumi nemaviri edhiziri pashift. Usakanganwa maturusi emwenje anopenya zvakanyanya ekushanda husiku; ma LED anonwa 0.6 L paawa zvichienzaniswa ne2.2 L ema bulbs ekare esimbi-halide. Mumwedzi wese purojekiti inochinja yega inochengetedza 1,150 L yemafuta—kwete kupwanya ivhu, asi yakakwana kubhadhara laptop itsva, handiti?

Maitiro Ekusarudza Fleet Yakakodzera Pasina Kuderedza Bhajeti

Tanga nemushumo wevhu renzvimbo: ivhu rakakora rakaenzana netsoka yemakwai pamwe nemarori emarasha e50 t. Jecha rakaita sejecha? Chinjana madhiramu akapfava nemarori e30 t. Tevere, nyora mepu yedaro rekutakura; mascrapers anotonga pasi pe2 km, marori anokunda kupfuura izvozvo. Pakupedzisira, tarisa matanho emuchina wemuno. Dozer yekupedzisira yeTier-4 inopisa mafuta mashoma ne7% pane Tier-3, ichideredza anenge 2 t yeCO₂ mumaawa emuchina chiuru. Vatengi vanoda nhamba iyoyo pavanotevera LEED credits.

Ngano Dzinowanzo shandiswa pakubvisa mari muzvikwama zvako

Ngano #1: “Mapaver makuru anogara akaenzana ne tonnage yakakwira.” Chokwadi: paver yemhando ye 10-m inogona kuisa 600 t paawa, asi kana chirimwa chako chikaburitsa 200 t chete, hofori inongomira—yopisa 25 L yedhiziri paawa isina kushanda. Ngano #2: “Unogona kusiya kugaya kana uchingowedzera 40 mm ye overlay.” Chokwadi: zvidimbu zvinopenya zvinoonekwa mumwedzi gumi nemisere, zvichimanikidza kuti zvidzokororwe zvizere. Kushandisa $1.20 pa square metre pakugaya pakutanga kunochengetedza $7.50 pakutsiva nguva isati yakwana. Ngano #3: “Ma rollers esimbi haadi mvura pamusanganiswa unopisa.” Anoda; pasina iyo asphalt inonamira, inodhonza, uye inosiya mitsetse inozova makomba.

Rondedzero Yekukurumidza Usati Wasaina Chibvumirano Chekurenda

• Roller ine upamhi hwedhiramu re 1 m here? (hongu, girama repamutemo, ndiko kutsveyamisa kwedu kwatinoda kuti tinzwike sevanhu)
• Ko paver iyi ine sensor yesonic auger here?
• Ko planer inotonhora inogona kuchinja madhiramu e1.2 m ne2 m mukati memaawa maviri here?
• Matowero emwenje anozadzisa here mutemo wekuti ruzha rwudzimwe nzvimbo (<55 dB pa50 m)?

Isa chiratidzo mumabhokisi iwayo uye uchadzivisa zvichemo zvakajairika zvinoderedza bhajeti ne15%.

Saka Ndeipi Mibairo Yechokwadi Yekuziva Midziyo Yako Yemugwagwa?

Kunzwisisa mhando dzakakodzera dzemidziyo yekuvaka migwagwa hakusi chinhu chisingawanzoitiki kune vane ruzivo rwemichina; ndiyo inonyanya kukosha kune varidzi vemidziyo yekuredza kuti vapedze mabasa nekukurumidza, vawane mabhonasi, uye vachengetedze traffic vachifara. Sarudza roller yakakodzera, sarudza upamhi hwakakodzera hwescreed, uye ronga kugadzira milling usati wagadzira pavement, uye unogona kubvisa 7-10% kubva pakurasikirwa nenguva uye zvinhu. Muchirongwa chemadhora mamiriyoni mashanu, mari iyoyo inodzokera kumadhora mazana matatu nemakumi mashanu kusvika mazana mashanu emadhora muchikwama chako—zvakakwana kuti uwane mari yebasa rako rinotevera mukwikwidzi wako asati apedza bhidhi. Hazvina kunyanya kuipa, handiti?
