Ukwenza indlela yezimayini iphephe, kudingeka umkhiqizo ofana ne-Split Set, Friction Bolt, Split Set Washer, Mining Mesh, Combi Plate, Strata Bolt, Rock Bolt, Mine Rock Bolt, friction stabilizer, njalonjalo.
yiziphi izinyathelo zokwakhiwa kwebholithi yezimayini okudingeka sizazi?Amaphuzu amahlanu alandelayo amaphuzu ayinhloko okwakhiwa kwebholithi yezimayini.Siyakwamukela ukuphawula kwakho.
1. Ukuma: Ngemva kokuba ingxenye isimbiwe futhi yafaneleka, dweba indawo yembobo yebhawodi lehange ebusweni bedwala, ngokuvumelana nezidingo zokuklama.
2. Ukumba: ukumba izidingo zobuchwepheshe: indawo yokuvula 38 ~ 42 mm;Ukuchezuka kokuvula kungaphansi kuka-2%, futhi ukujula kwembobo kungu-3 ~ 5cm ubude kunengxenye yokufaka yebhawodi.
3. Ukufaka ipuleti le-combi: zengezwa emsileni wentonga yehange ngemva kokuqedwa kwe-grouting.Ngemva kokukhipha i-grout amahora angu-24, qinisa inathi, amandla okuqinisa ngo-10KN/m~20KN/m angcono.
4. Faka ibhawodi lemayini kancane kancane ngamasentimitha ama-3 ukuya kwangu-5 ukusuka phansi kwembobo.Ngemuva kokufakwa komzimba wenduku, imbobo kufanele ixhunywe ngokuqinile nge-cement slurry noma ezinye izinto ngesikhathi, futhi imbobo yokukhipha kufanele imiswe.
5. I-grouting yebholithi yezimayini: ukucindezela kwe-grouting kufanele kube phakathi kuka-0. 5 kuya ku-0. 8Mpa, ukuze umjovo we-grout kancane kancane, lapho kukhona i-grout ephuma emgodini we-bolt yezimayini, vala imbobo yokukhipha umoya, umjovo wengcindezi ezinzile 3 ~ Imizuzu emi-5 ngemuva kokumisa i-grouting.
