Izingxenye zokubhola ze-Compaction Grouting

Ukucindezela nokugcwalisa umhlaba kuyindlela ekhethekile yokuthuthukisa umhlaba esetshenziswa izinsiza zokubhola ukuze kufakwe umjovo wokugcwalisa onokwenziwa ngencibilikisi ethile emhlabathini ongaqinile noma okhanya ngezansi kwezindawo ezikhona noma ezihlelwe. Le nqubo, eyaziwa ngokuthi ukugcwalisa kwesixazululo noma ukugcwalisa ngengcindezi, ihilela ukumbola izimbobo ezibekezelwe kahle ukuze kufinyelelwe ezindaweni ezithile lapho umjovo wenziwa ngaphansi kwengcindezi elawulwayo. Umjovo owenziwe udala umphumela wokukhukhula emhlabathini, uqhubekisela phambili ubunzima bezinto ezixubile ezifana nesihlabathi esinokukhula, igwababa, nezindawo ezinkulu. Izinsiza zokubhola ezihlinzekwe ngama-sistimu okugcwalisa akubalulekile kulolu hlelo, njengoba kufanele zibe neziqu ezihloniphekile, zigcine izindlela zokubola ezihambisanayo, futhi zisekele imishini yokucindezela edingekayo ukuze kuqinisekiswe ukuphakelwa kokugcwalisa okuphumelelayo. Le ndlela ibaluleke kakhulu ezindaweni zasemadolobheni nasezindaweni ezakhiwe kakhulu lapho izindlela zokumba eziwujwayelekile nezokucindezela zingasebenzi kahle noma zingadala ukuphazamiseka okungekho emthethweni ezakhiweni eziseduze. Indlela yokucindezela nokugcwalisa umhlaba ngokusebenzisa izinsiza zokubhola ibamba iqhaza elihlelwe kahle lokubhola, ukubeka indlela yokucindezela, nokugcwalisa umjovo. Izinsiza zokubhola zishaya izinsika zokugcwalisa ezindaweni ezithile, zidalela ezikhala ngaphakathi komjovo ukuze kuhlawulwe umjovo ngendlela elawulwayo. Njengoba umjovo ugcwaliswa ngaphansi kwengcindezi, udala ibhola lomhlaba othi ukhanyise eduze komjovo, kancane kancane uthuthukisa amandla okubamba nokunciphisa ithuba lokuhla komhlaba. Ochwepheshe bahlola ingcindezi yokugcwalisa, izinga lokugeleza, nokuphendulwa komhlaba ngesikhathi sangempela ukuze kuqinisekiswe ukufinyelela okuphakeme kwendawo yokuhlala ngenkathi bephatha umkhuba wokwenyuka nokwehlisa umthelela kwezimo ezizungezile. Le ndlela yokugcwalisa elawulwayo ihluke ezindleleni zokugcwalisa ezijwayelekile futhi idinga izinsiza zokubhola ezineziqu ezanele, ukuzinzile, nokuhambisanisa nezinhlelo zokugcwalisa ezicindezelwe. Uhlelo lokugcwalisa, ngokuvamile luhlobo lwe-mortar eqinile ye-cement nesihlabathi, luphikisa ukugeleza phakathi kwezikhala zomhlaba, kuqinisekiswe ukusebenza okuphezulu kokucindezela esikhundleni sokugcwalisa. Izicelo zokucindezela nokugcwalisa umhlaba ngezinsiza zokubhola zifaka izimo ezahlukene zokwakhiwa, kuhlanganisa ukuthuthukiswa kwezinsiza ezikhona, ukunciphisa ingozi yokuphola ezindaweni ezinesimo esithokozisayo, ukwehliswa komhlaba ngaphansi kwezindlu ezibucayi, nokuqhubekisela phambili umhlaba ngaphambi kokwakha okujwayelekile ezindaweni lapho izinga lomhlaba lihluka khona. Amaqembu abachwepheshe asebenzisa le ndlela ukuze baxazulule izinkinga zokuhla ezibangela ukuvele kwensimu, ukwakhiwa komhlaba okuhlangene, noma ukucindezeleka okungahambi kahle. Izinsiza zokubhola zenza kube lula ukufinyelela ezindaweni ezithile ezingafani, ukugudluza phakathi kwezinsiza ezikhona, nokugcina ukunemba kweziqu zokuqonda kusebenza kohlaka olusemkhakheni. Amabhizinisi aqhubeka nalesi sikhungo sokuthuthukisa umhlaba afaka ukuthuthukiswa kwezinsiza, ukwakhiwa kweziqu nezinye izibhakabhaka, ukuphucula indlela yokusebenza kwezindiza, nokwengeza izakhiwo ezinhle ezifuna umphakathi wokuvikela ngaphandle kokumba okukhulu noma ukukhishwa.
