Raws li kev ua kom tiav cov khoom cua ua kom tiav, yuav tsum muaj lub hauv paus, yuav tsum ua kom muaj lub luag haujlwm zoo nyob hauv cov av txheej txheem, qhov zoo ntawm lub hauv paus yuav tsum muaj tsawg tshaj li qhov yuav tsum tau ua kom muaj qhov nyuaj, qhov chaw nyob thiab qhov dej qis, ib lub xeev zoo tshaj.
Nws muaj peb lub ntsiab ntawm cov cag cem cog qoob loo, namely asphalt foundation, cement foundation thiab gravel foundation. Qhov twg yog qhov tau xaiv nyob ntawm qhov kev nyab xeeb hauv zos thiab qhov kev tsim nyog rau qhov project.
Rau cov hom kev ua lag luam ntawm cov pob zeb, tab sis lub hauv paus ntawm cov gravel yog yooj yim hauv kev tsim kho, tsis tshua muaj nqi thiab ceev hauv cov kua, vim nws cov pligidity ploj thiab stability, nws yuav tshwm tsis ntev tom qab siv ntev, ua rau tsis sib txawv ciav dag . Yog li ntawd, qhov kev ua tau zoo ntawm cov cement foundation yog tus muaj siab.
Thaum lub pob zeb cog hniav cement yog siv, qhov kev thov ntawm qhov chaw ntiav nyob siab dua, vim tias nws ncaj qha rau cuam tshuam cov thickness thiab elastic uniformity ntawm qhov khoom neeg tsim nyom txheej txheej, ces lub tiaj tus ntawm cov cement foundation yuav tsum tswj saum 95%.
Txij li nws yog lub hauv paus ntawm cov khoom cua dag, nws yuav tsum muaj lub zog thiab kev ruaj ntseg, thiab nws tsis muaj cai muaj qhov tsis xws li kev tawg thiab lwj ntug. Nws zoo dua los npaj dicing ntawm 6000mm × 6000mm. Tsis tas li ntawd, lub hauv paus cement yuav tsum tau muab nrog ib txheej dej, uas yuav ua tau ntawm PVC tuab cov dej thau dej.
Thaum siv txoj kev tsim, ib qho kev sib txuas expansion yuav tsum tau sab laug rau lub pob zeb zom zaws sab laj kom tsis txhob muaj teebmeem tshwm sim los ntawm thermal expansion thiab contraction. Feem ntau, lub caij nyoog ntawm cov khoom cua dag yog 2-3 lub lis piam. Tom qab lub sijhawm no, lwm qhov ntawm kev tsim kho yuav pib.
