Ingxenyenamba - kuyinto ipharamitha ebalulekile Ukukhetha ngohlalwane nesihlabathi ukuze kwakhiwe

nezixhobo Okuxekethile noma izinto zokwakha eziyisisekelo ngokuhambisana namazinga obuchwepheshe ayahluka ngobukhulu. Lapho ukuhlunga izinto by sieving ngokusebenzisa ingxenyenamba ngesihlungo kunqunywa uhlelo. Lokhu kusho ukuthi amatshe noma esihlabathini ahlukaniswa ngekwesayizi kuyizinhlayiyana noma okusanhlamvu.

Yini ingxenyenamba kuyinto imfucumfucu?

Indaba ezivamile ahlale kunoma isiphi isakhiwo kuyinto imfucumfucu. Isetshenziselwa traffic kudivayisi ezihlalweni endaweni abayizimpumputhe, lingena ingxenye ukhonkolo ingxube. Esimweni ngasinye usebenzisa usayizi eqondile itshe uchotshoziwe nezici zabo ezingokomzimba esingokwemvelo. GOST inikeza ukuthi ingxenyenamba - silingana iyunithi ngokomzimba zamatshe ihlangana ku uhlaka oluthile olumisiwe. Kukhona main ingxenyenamba ezimbili okujwayelekile (5-25 mm 25-60 mm), okuyinto esetshenziswa ukwakhiwa. Imishini zisenza sikwazi ukuba zivundulula emfucumfucwini namagugu ewumngcingo ukuthi ziyadingeka ukuqaliswa imisebenzi ngabanye - kusukela komncane (kufika ku 1 cm) kuya ku- (12 kuya ku-30 amasentimitha) ende kakhulu.

Kungani isidingo amatshe?

Industrial ukukhiqizwa ukhonkolo futhi wasisekela izakhiwo zikakhonkolo, kanye sihlinzekela ukusetshenziswa asphalt ochotshoziwe izinhlawulo itshe - 5 kuya ku-20 mm. Lapho tramways kudivayisi, ujantshi embankments ngoba othelawayeka imicamelo ngokuvamile sisebenzise chips itshe elikhulu (ingxenyenamba 20/65 noma 40/70 mm).

amafraktjhini elikhulu efanelekayo ukwakhiwa izisekelo netshe elikhulu elisetshenziswa engadini - ngamasentimitha angu-30.

Ngakho, ingxenyenamba - silingana amatshe, ukukhethwa zokugcina, ukuqeqeshwa nokuhlolwa ngokuhambisana nezidingo GOST.

I-eksponenti ezivamile zonke itshe amafraktjhini Kusolwa cuboid kuyizinhlayiyana ukuma, okuyinto ibangelwa enqubeni yokuwela.

I amafraktjhini yesihlabathi Ububanzi

Sand isetshenziswe kuphela ukwakhiwa kodwa futhi umkhakha, isibonelo ukwenziwa heater noma ingilazi, ukukhiqizwa kwanoma ingcina futhi yomile amamiksi, fillers, iphansi yokululama, isikhunta ekufezeni imisebenzi sandblasting. Ukuze ugweme izinkinga ne Ukukhetha izinto zokusetshenziswa, kubalulekile ukwazi izimfanelo futhi uthenge ncamashi esihlabathini, okuyilona elidingekayo ukuze umuntu uhlobo oluthile lomsebenzi.

Faka kusigaba esihlabathini kuye umsuka kanye processing indlela. Uyena emfuleni, olwandle, ama-career, asebenza ngebhethri, Perlite, futhi ngayinye kukhona idokhumenti zokulawula. Ngokwesibonelo, amazinga GOST elawula imingcele izimpahla ezisetshenziselwa usimende ukuhlolwa ukuhlukanisa monofraktsionny multifractional futhi asebenza ngebhethri isihlabathi. Izikhombo ubhekwa esihlabathini imali Cretaceous kwendawo Czech.

Isici esivamile ngoba kwezihlabathi umsuka ezahlukene iyona wemfihlo fineness (ingxenyenamba) - lapho iningi izinhlayiya of ngobukhulu efanayo. Ngakho, ukuze bathwale isihlabathi enkulukazi ehlanganisa okusanhlamvu afika ku 0.5 cm ububanzi. Vala - 2.5-3.5 mm, naphakathi - 1-2.5 mm, amancane - kusuka kwangu 0.5 1.5, futhi ezincane usayizi izinhlamvu "isihlabathi mncane" isigaba.

River isihlabathi - ekahle impahla eluhlaza for imikhiqizo ukhonkolo, futhi umsebenzi - yokuhlanganisa wokwakha noma kakhonkolo, umsebenzi isisekelo. Silica isihlabathi is okungcono osetshenziselwa ukukhiqizwa izihloko polymeric futhi tile, zobumba kanye zobumba, amanzi filtration, Welding impahla kanye ekubunjweni isikhunta.
