Mushure mekudururira kongiri, zvinodikanwa kupfapfaidza mvura nguva nenguva kuti ugadzire humwe hunyoro, kuitira kuti hwaro husanyanya kuoma. Dzivisa mvura inonaya kwenguva refu kwemazuva mazhinji ichakonzera chiitiko chesimende yakafa. Mukuwedzera, inofanirwawo kudzivisa chiedza chezuva, usarega chiedza chezuva chakawandisa chichikonzera kuti kongiri iparadze. Concrete kuchengetedza nguva inofanira kunyatsoongororwa, kunyanya 1 kusvika 2 mazuva mushure mokunge kongiri itsva yadururwa. Ita shuwa kuti kongiri yakanyatso sungwa uye yakachengeteka kuti isanyura kana buri.

Kunze kwezvo, zvinofanirwa kucherechedzwa kuti dhizaini ye raft nheyo pane isina simba pasi ndiyo inonyanya kukodzera. Kune rumwe rutivi, izvozvo hazvirevi kuti pasi richabvumirwa kuva pangozi yekuderera. Mushure mekuvaka, zvakakosha kugadzirisa kugadzirisa kuti ive yakaenzana kana kwete, kana zvisina kudaro kuwanda kwenheyo kuchave kusina kuenzana. Kukanganisa kwakakomba pamatanho ekupedzisa kuvaka gare gare.

Uyezve, pakugadzira faundesheni, mirwi chinhu chakakosha kuendesa mutoro kuchivakwa. Naizvozvo, kutarisisa kunofanirwa kubhadharwa kune kurongeka kwemurwi spacing maererano nezvinodiwa zverudzi rwebasa. Kukwanisa kuita zvakanyanya kuderedzwa kwesimba regiravhiti mu raft ndiyo yakakwana uye yakachengeteka.

Zviyero uye kudhirowa kweiyo raft nheyo dzedzimba

Zvimiro zviyero, raft hwaro dhizaini mumadhirowa

Kuti uve neyakaomeswa yakajairwa raft hwaro, zvinodikanwa kuve neyakaonda kongiri lining, iyo nheyo slab inopararira pasi pechimiro uye hwaro danda. Paunenge uchigadzira raft nheyo, kune 4 mhando dzekutanga mudhirowa, ine zviyero zvakasiyana zvemhando yega yega. Inogona kushandiswa ne raft misumari propeller claws mune dzimwe nzvimbo kana nzvimbo yekuvaka isina kuchengetedzwa zvakakwana.

Kuve nechokwadi chekumisikidzwa kwehwaro hwema raft evanhu
  • Kumaplateti akafuratira: Inonyanya kuzivikanwa ndeyekukora kwe slab, ine coefficient e yakasarudzwa = (⅙) l, ine chinhambwe pakati pembiru l <9m, chiyero che tonnage chinotsanangurwa ndeye 1000 tons / column.
  • Kune reverse plate: Rudzi urwu runoshandiswa kumapurojekiti ane hombe kubhenda zvinodiwa. Kune mapurojekiti epakati-kati, arch inogona kusarudzwa sechidhinha uye chimiro chematombo, kongiri yakasarudzwa ine e = (0,032 l + 0,030) m uye arch deflection f = 1/7l ~ 1/10.
  • Kurudzi rwembabvu: Iyo yakajairwa parameter yeukobvu hwembabvu hwaro ine e = (1/8)l ~ (1/10) , nekupatsanurana kwemakoramu l > 9m. Kune mafomu maviri ekuumbwa kwembabvu: yezasi mbabvu ine trapezoidal cross-section uye yepamusoro mbabvu.
  • Yemhando yebhokisi: Iyi ndiyo inonyanya kushandiswa raft hwaro nekuda kwekugadzirisa kwayo uye kugona kugovera simba zvakaenzana. Iyo bhokisi-yakaita raft hwaro inokodzera dzimba dzine 2 pasi kana kupfuura. Kunyangwe zvakadaro, rudzi urwu rwe raft hwaro rwakareruka muhuremu nekusimba kwakanaka. Saka iyo yakaoma ichave yakaoma uye inoda simbi yakawanda kuti ishandiswe.

Kuti uverenge iyo raft hwaro chimiro, zvinodikanwa kupatsanura nenzvimbo kuti ive nechokwadi chekuchengetedza, pamwe nekubatsira mukudzikisa mutengo.

Semuenzaniso: Chirongwa chekuvaka imba ine zviyero zve6m x 5m inorema matani makumi matanhatu, kusarudza hwaro hwe raft pakuvaka. Ipapo iyo raft hwaro dhizaini ine simba rekubereka ichaverengerwa nenzira inotevera:

Uremu hwebasa / Yese yekuvaka nzvimbo = 60 matani / 30 m2 = 2 (matani). Zvinogona kuonekwa kuti chimiro chinoda kuvaka raft nheyo pano inokwanisa kubereka 2 tons / m2.

Nekudaro, kana iyo raft hwaro iine tsigiro yekoramu, iyo inotakura simba inoda kuwedzerwa zvakanyanya. Semuenzaniso, nebasa riri pamusoro, kana paine mamwe makoramu mana x 4m, iyo yakazara nzvimbo yenheyo ichave 1 m4. Kuita pasi kwaizobva kwaita 2/60, iyo yaizodonha kusvika pa16 tons/m12. Saka, iyo yakazara nzvimbo yenheyo inowedzera, ichikonzera kupokana kwepasi, saka kuvaka kwacho kunoderera zvakanyanya.

Saizi yakajairika

Chiyero che raft nheyo saizi yakafanana ne mukombe chipikiri uye inofanirwa kuve nechokwadi zvinotevera:

  • Kongiri ye slab layer inoda kuva masendimita gumi
  • Kureba kwekongiri nheyo kunofanirwa kunge kuri 3200 mm.
  • hwaro danda saizi, foundation wall chiyero ndeye 300 × 700 mm

Material standards pakugadzira raft nheyo

  • Standard simbi ndiro kushandisa 2 akaturikidzana asiri 12a200
  • Yakajairika simbi simbi nheyo inoshandisa 6 phi (20-22) longitudinal simbi, itsva 8a150 bhandi simbi kuti ive nechokwadi chekuchengetedzwa kweprojekti yese.
