Mfundo zazikuluzikulu zoyendetsera kuyezetsa maziko a milu

Nthawi yoyambira kuyesa maziko a milu iyenera kukwaniritsa izi:

(1) Mphamvu ya konkire ya mulu woyesedwa sayenera kukhala wotsika kuposa 70% ya mphamvu ya mapangidwe ndipo sayenera kukhala yotsika kuposa 15MPa, pogwiritsa ntchito njira ya kupsyinjika ndi njira yotumizira ma coustic poyesa;

(2) Pogwiritsa ntchito njira yobowola poyesa, zaka za konkire za mulu woyesedwa ziyenera kufika masiku 28, kapena mphamvu ya chipika chochiritsidwa chochiritsidwa pansi pamikhalidwe yomweyi iyenera kukwaniritsa zofunikira za mphamvu;

(3) Nthawi yopumula isanayesedwe: maziko a mchenga sadzakhala masiku osachepera 7, maziko a silt azikhala osakwana masiku 10, nthaka yolumikizana ndi unsaturated idzakhala yosachepera masiku 15, ndi dothi lodzaza ndi dothi lokhazikika. masiku osachepera 25.

Mulu wosungira matope uyenera kuwonjezera nthawi yopuma.

Zosankha za milu yomwe yawunikiridwa kuti iyesedwe kuvomereza:

(1) Milu yokhala ndi khalidwe lokayikitsa la zomangamanga;

(2) Milu ndi mikhalidwe yolakwika ya maziko;

(3) Sankhani milu ya Gulu la III kuti mulandire kuvomereza;

(4) Phwando lokonzekera limawona milu yofunika;

(5) Milu yokhala ndi njira zosiyanasiyana zomangira;

(6) Ndibwino kuti tisankhe mofanana komanso mwachisawawa malinga ndi malamulo.

Mukayesa kuvomereza, ndikofunikira kuti muyambe kuyesa kukhulupirika kwa mulu, ndikutsatiridwa ndi kuyezetsa mphamvu.

Kuyesedwa kwa umphumphu wa thupi la mulu kuyenera kuchitidwa pambuyo pofukula dzenje la maziko.

Umphumphu wa thupi la mulu umagawidwa m'magulu anayi: milu ya Kalasi I, milu ya Gulu II, milu ya Gulu lachitatu, ndi milu ya Gulu IV.

Mulu wa mtundu wa I ulibe;

Milu ya kalasi yachiwiri imakhala ndi zolakwika pang'ono mu mulu wa thupi, zomwe sizingakhudze mphamvu yobereka ya mulu;

Pali zolakwika zoonekeratu mu mulu thupi la Class III milu, amene zimakhudza structural kunyamula mphamvu ya mulu thupi;

Pali zolakwika zazikulu mu mulu wa milu ya Class IV.

Mtengo wamtengo wapatali wa mphamvu yonyamulira ya mulu umodzi uyenera kutengedwa ngati 50% ya mphamvu yomaliza yonyamulira ya mulu umodzi.

Makhalidwe a mphamvu yonyamulira yonyamulira ya mulu umodzi iyenera kutengedwa ngati 50% ya mphamvu yomaliza yotulutsa mulu umodzi.

Kutsimikiza kwa mtengo wamtengo wapatali wa mulu wopingasa wa mulu umodzi: choyamba, pamene thupi la mulu sililoledwa kusweka kapena kulimbitsa chiŵerengero cha mulu woponyedwa m'malo osakwana 0.65%, 0,75 nthawi yopingasa. katundu wovuta adzatengedwa;

Kachiwiri, kwa milu ya konkire yokhazikika, milu yachitsulo, ndi milu yoponyedwa pamalo omwe ali ndi chiwongolero chosachepera 0.65%, katundu wofanana ndi kusamuka kopingasa pamilu yokwera pamwamba pamilu iyenera kutengedwa ngati nthawi 0,75 (yopingasa). mtengo wakusamuka: 6mm kwa nyumba zomwe zimakhudzidwa ndi kusamuka kopingasa, 10mm kwa nyumba zomwe sizikhudzidwa kusamutsidwa kopingasa, kukwaniritsa zofunikira za kukana kwa thupi la mulu).

Pogwiritsa ntchito njira yobowola pachimake, chiwerengero ndi zofunikira za malo pa mulu uliwonse wowunikiridwa ndi izi: milu yokhala ndi m'mimba mwake yosakwana 1.2m ikhoza kukhala ndi mabowo 1-2;

Mulu wokhala ndi mainchesi 1.2-1.6m uyenera kukhala ndi mabowo awiri;

Milu yokhala ndi m'mimba mwake yoposa 1.6m iyenera kukhala ndi mabowo atatu;

Pobowola ayenera kukhala wofanana ndi symmetrically anakonza mu osiyanasiyana (0.15~0.25) D kuchokera pakati pa mulu.
