Izingxenye ze-Jet Grouting ezisekelwe kwi-Rig ye-Anchor

Emkhakheni wokwakhiwa kwemigodi ejulile kanye nezinjini ze-geotechnical, ama-rig okwakha i-jet grouting esekelwe kumathoni anendima ebalulekile ekwenzeni kube lula ngokwakha umhlabathi nokwenza izimo zomhlaba zibe ngcono. Lezi zinsiza ezikhethekile zenziwe ukuze zisebenze i-jet grouting, indlela esebenzisa amathoni aphezulu we-grout ye-cementitious ukuvala amakholomu omhlaba akhona. Le nqubo ishintsha kahle izimfanelo zomhlabathi okhona, iyenza ifanele izinhlelo eziningi zokwakha. Ukusebenza kwezimoto ze-jet grouting ezisekelwe kumathoni kuhlanganisa ukusetshenziswa kokudrila okuyi-rotary okuvulelekile ngesistimu yokujikisa. I-drill ithola umhlaba kuzo zonke izindlala ezifunekayo, futhi ngok simultaneously ifaka umxube wamanzi, isigaxa, nezithako ngengcindezi ephakeme ngaphezulu kwezikhala ezikhethekile. Le ndlela akugcini nje ngokwenza umhlabathi uqine kodwa futhi inciphisa ingozi yokuhluka nokuphuka kwi-structures, iyenza ibe indlela ebaluleke kakhulu emiphakathini ejulile, njengokwakhiwa kwezindawo zokuhlala, amabhuloho, nezakhiwo ezingaphansi komhlaba. Izinhlelo ezibalulekile zemoto ye-jet grouting ezisekelwe kumathoni zihlanganisa ukuthuthukiswa komhlaba ukuze usekele izisekelo, ukuvuselela ukunemba, nokuqanjwa kwamathunhu angaphansi nokhole. Lezi zimoto zisebenza kahle ikakhulukazi emhlabathini ongaqinile noma ocezelekile, lapho izindlela zokwakha ezijwayelekile zingase zingahlinzeki amandla afanele. Ngaphezu kwalokho, zisetshenziswa kabanzi emiphakathini yokuphulukisa imvelo, lapho umhlabathi onokungcoliswa kudingeka ukwenzelwa in situ, kunciphisa isidingo sokumba okudinga izindleko eziphezulu nezithiyo. Nxa ukhetha imoto ye-jet grouting esekelwe kumathoni, kufanele kubhekwe izincazelo ezithile nezimfuneko ezahlukahlukene. Amandla wokudrila emoto, ngokuvamile atholakala ngezinga lesimo nokuqhubeka, abalulekile ukuze kube nokuhlola okusebenzayo. Amandla okucindezela kwesistimu yokujikisa, kanye ne-.flow rate ye-pump, yakhona ithonya uqobo nobukhulu be-grout column eyakhelweyo. Ngaphezu kwalokho, ukuhamba kwemoto nosayizi kubalulekile ukuze ukwazi ukwethula endaweni, ikakhulukazi ezindaweni zasemadolobheni noma ezindaweni ezinzima. Ngaphezu kwalokho, ukukhethwa kwemoto kufanele kuhambisane nezidingo zephephandaba zomsebenzi, njengohlobo lomhlaba, ubude bokugrouta, nezimo zemvelo. Ukuhambisana nezinhlobo ezahlukene ze-grouts nezithako kuyinto ebalulekile, ngoba ivumela izixazululo ezithuthukisiwe ezihambisana nezinkinga ze-geotechnical ezahlukene. Ngamafuphi, ama-rig e-jet grouting esekelwe kumathoni angamathuluzi abalulekile emkhakheni wokwakha kwemigodi ejulile nasezinhlelweni ze-geotechnical, anikela ngezixazululo advanced zokuthuthukiswa komhlaba nasekuzinziseni. Ikhono lawo lokwenza izakhiwo zibe ngcono ngendlela engabizi lishintsha kube ufuna okubhekelela abaqashi kanye nabaklami. Njengoba isidingo sezixazululo ezisungulayo sokwakha sikhula, ukutshalwa kwezimali ku-rig ye-jet grouting ephezulu kungasiza kakhulu empumelelweni yanoma iyiphi iphrojekthi ye-geotechnical.
