Koyefishienti potero mchenga - kofunika chigawo kusankha zinthu

Sand ntchito zosiyanasiyana ya zomangamanga, motero ndikofunika kudziwa mmene kuwerengera chofunika kuchuluka kwa nkhaniyi. Ngati kumachitika metering ndi buku, n'kofunika kuganizira chizindikiro monga mchenga compaction chiŵerengero (chidule wogula). Ndi chofunika kwambiri pa mawerengedwe izi. chizindikiro ichi nkofunika tonse timvetsetse mmene compaction.

Voliyumu ya nkhani

Pa anati chizindikiro zingakhudze zinthu zingapo kunja, monga mode ndi osiyanasiyana ophimba pa. Kupewa kusintha mu buku la mchenga, m'pofunika kuti athe kuziteteza zisaonongeke makina ndi ingress chinyezi ndi zinthu zakunja. Chongani nkhaniyi ayenera kutenga malo pomwepo pa phwando, ndiye kuti wolandila sananene zofunika. The mawerengedwe a chizindikiro ichi kumva. Kuti izi ziyenera kuchulukitsa ndi kuchuluka lenileni la nkhaniyo pa koyefishienti chidindo mchenga. Pali ugule, anaika kale ndi GOST 9757-90. Sitiyenera kuposa 1,15. Kudziwa kuchuluka zenizeni zofunika kuchita muyeso wa voliyumu ya thupi, koma zimatengera kutalika lenileni la nkhaniyo, osati mbali.

mchenga compaction chiŵerengero

chizindikiro ichi zimadalira:

• Kutentha ndi chinyezi. Mwachitsanzo, m'nyengo yozizira angaoneke apezeka mazira. buku lawo komanso kulembedwa.
• zinthu ophimba.
• Zofunika zakuthupi gulu malinga GOST 25100-95 ndi GOST 8736-93 kumene chinyezi yake ya chibadwidwe ndi osalimba ndi mwakutimwakuti.
• mchenga compaction chiŵerengero chimadaliranso kumene analandiridwa. Mwachitsanzo, nkhani dzenje ndi wosiyana ncho mu mulu wa.

Nkofunika kuganizira chinthu cha compaction wachibale wa mchenga. chithunzi Izi ziri zofunika ndi mawerengedwe anati. Kwenikweni ndi chiŵerengero cha osalimba a zakuthupi "youma" (mafupa). Izi amaganizira mchenga compaction chiŵerengero (SNP 2.05.02-85) kuti chizindikiro chomwecho kupeza gwero.

Yowerengera kumatengera zifukwa zingapo:

• Kuyambira makhalidwe a gwero lake, kumene zinthu chinapezeka (hayidiroliki alluviation, miyala).
• Pa zinthu nyengo.
• Kuchokera zoyendera chiwembu cha yobereka chuma kuika malo.
• Pa deta pasipoti gwero. Pali zinalembedwa deta monga khalidwe la mchenga, kachulukidwe zachilengedwe ndi chinyezi ndi zina zotero.

Council

Pakuti mtima wa zizindikiro zina ayenera kudziwa kuchuluka kwa chuma chitsanzo kwa kuya padziko masentimita za 20-25 ndi masentimita osachepera 50 ku makoma a thupi. Nkofunika phunzirolo. Zitsanzo za nkhaniyi ayenera kukhala mogwirizana ndi GOST 12071-84. Komanso, aliyense wa iwo ayenera kukhala nacho chizindikiro motsatana, limene deta zofunika ziyenera mwasankha. Kumbukirani kuti kudziteteza ku zina ndalama pa ntchito, m'pofunika poyamba kuwerengera muyezo wa mchenga. Kutanthauza mchenga compaction chinthu n'kofunika kwambiri pomanga misewu, chifukwa limakhudza mphamvu structural.
