Ukwenza indlela yokumbiwa kwemigodi ikhuselekile, kufuneka imveliso efana neSplit Set, Friction Bolt, Split Set Washer, Mining Mesh, Combi Plate, Strata Bolt, Rock Bolt, Mine Rock Bolt, friction stabilizer, njalo njalo.
ngawaphi amanyathelo okwakhiwa kwebholi yemigodi ekufuneka siwazi?Amanqaku amahlanu alandelayo ngamanqaku aphambili okwakhiwa kwebholi yemigodi.Wamkele izimvo zakho.
1. Ukuma: Emva kokuba icandelo ligrunjwe kwaye lifanelekile, zoba indawo yomngxuma we-anchor bolt ebusweni belitye, ngokweemfuno zoyilo.
2. Ukugaya: iimfuno zobugcisa bokuqhuba: i-aperture 38 ~ 42 mm;Ukuphambuka kokuvula kungaphantsi kwe-2%, kwaye ubunzulu bomngxuma bu-3 ~ 5cm ubude kunenxalenye yokufakwa kwebholithi.
3. Ukufakela i-combi plate: yongezwa kumsila wentonga ye-anchor emva kokuba i-grouting igqityiwe.Emva kwe-grouting iiyure ze-24, qinisa i-nut, i-fastening force in 10KN / m ~ 20KN / m ikhethwa.
4. Faka ibholithi kancinane ka-3 ukuya kwi-5 yeesentimitha ukusuka ezantsi komngxuma.Emva kokuba umzimba wentonga ufakwe, umngxuma kufuneka ufakwe ngokuqinileyo nge-samente slurry okanye ezinye izinto ngexesha, kwaye umngxuma wokukhupha kufuneka umiselwe.
5. Ukugrumba ibholithi yemigodi: uxinzelelo lwegrouting kufuneka lube malunga ne-0. 5 ukuya ku-0. 8Mpa, ukuze isitofu esicothayo, xa kukho i-grout ephuma kumngxuma webholi yemigodi, vala umngxuma wokuphuma, inaliti yoxinzelelo oluzinzileyo 3 ~ Imizuzu emi-5 emva kokumisa i-grouting.
