Qum- shag’al aralashmasini optimal namligini taminlash uchun suv sepuvchi mashina tanlaymiz.
Qum - shag’al aralashmsidan asos qurish
Yo’l to’shama konstruktsiyasi SHNQ 2.05.02-07 va SHNQ 3.06.03-08 talablariga amal qilgan holda quriladi. Qum-shag’al aralashmasi (QSHA) li asosni qurishda smenali ish ko’lamini etakchi mashinaning ish unumdorligiga qarab aniqlanadi.
Yo’l poyining ustki qsmiga, asosning quyi qatlamni qurish material turi.
Qum-shag’al aralashmasi
QSHAsini ekskavatr yordamida yuklaymiz.
Ekskavatrning ish unumdorligini aniqlaymiz.
