Vim li cas feem ntau cov kav hlau yog 6 meters ib daim?

Vim li cas feem ntaucov kav hlau6 meters ib daim, es tsis yog 5 meters lossis 7 meters?

Hauv ntau daim ntawv xaj yuav hlau, peb feem ntau pom: "Qhov ntev txheem rau cov kav hlau: 6 meters ib daim."

Piv txwv li, cov kav dej vuam, cov kav dej galvanized, cov kav dej plaub fab thiab plaub fab, cov kav hlau tsis muaj seamless, thiab lwm yam, feem ntau siv 6m ua tus qauv ntev ib daim. Vim li cas ho tsis yog 5 meters lossis 7 meters? Qhov no tsis yog ib qho "kev coj ua" ntawm kev lag luam xwb, tab sis yog qhov tshwm sim ntawm ntau yam.

6 meters yog qhov "ntev ruaj khov" rau feem ntau cov kav hlau

Ntau lub teb chaws cov qauv hlau (piv txwv li, GB/T 3091, GB/T 6728, GB/T 8162, GB/T 8163) qhia meej meej: Cov kav hlau yuav raug tsim tawm hauv qhov ntev ruaj khov lossis tsis ruaj khov.

Qhov ntev ruaj khov uas siv ntau: 6m ± qhov kam rau siab. Qhov no txhais tau tias 6 meters yog qhov ntev uas lees paub thoob tebchaws thiab muaj ntau tshaj plaws.

Kev Txiav Txim Siab Txog Cov Khoom Siv Tsim Khoom

Cov kab tsim cov yeeb nkab vuam, cov chaw tsim cov yeeb nkab plaub fab thiab plaub fab, cov tshuab kos duab txias, cov tshuab ncaj, thiab cov tshuab kav dej kub dov uas ntev tas li—6 meters yog qhov ntev tshaj plaws rau feem ntau cov tshuab dov thiab cov kab tsim cov yeeb nkab vuam. Nws tseem yog qhov ntev yooj yim tshaj plaws los tswj kom ruaj khov. Qhov ntev dhau ua rau: kev nruj tsis ruaj khov, kev nyuaj rau kev sib txuas/txiav, thiab kev co ntawm cov kab ua haujlwm. Qhov ntev luv dhau ua rau cov zis tsawg dua thiab cov khib nyiab ntau ntxiv.

Kev txwv kev thauj mus los

Cov kav dej 6-meter:

• Tsis txhob muaj kev txwv loj dhau
• Tshem tawm cov kev pheej hmoo ntawm kev thauj mus los
• Tsis tas yuav muaj daim ntawv tso cai tshwj xeeb
• Ua kom yooj yim rau kev thauj khoom / tshem tawm
• Muab cov nqi qis tshaj plaws

Cov kav dej 7-8-meter:

• Ua kom muaj kev thauj mus los ntau ntxiv
• Ua kom muaj kev pheej hmoo loj heev
• Ua rau cov nqi logistics nce siab heev

6 meters yog qhov zoo tshaj plaws rau kev tsim kho: pov tseg tsawg, txiav yooj yim, thiab cov kev cai tom qab txiav ntu (3 m, 2 m, 1 m).

Feem ntau cov xwm txheej kev teeb tsa thiab kev ua tiav xav tau cov yeeb nkab ntev li ntawm 2-3 meters.

Qhov ntev 6 meter tuaj yeem txiav ua 2 × 3 m lossis 3 × 2 m seem.

5 meter ntev feem ntau xav tau kev txuas ntxiv vuam rau ntau qhov project;

Qhov ntev 7 'meter' nyuaj rau kev thauj mus los thiab hoist, thiab yooj yim rau kev khoov deformation.

Qhov ntev 6-meter tau dhau los ua tus qauv feem ntau rau cov kav hlau vim nws ua tau raws li: cov qauv hauv tebchaws, kev sib raug zoo ntawm cov kab ntau lawm, kev yooj yim thauj mus los, kev siv tau yooj yim, kev siv cov khoom siv, thiab kev txo nqi.
