1. Isishwankathelo seprojekthi
Iprojekthi ithatha ulwakhiwo oluvulelekileyo. Ukuba ubunzulu bomgodi wesiseko bukhulu kuneemitha ezi-3 kwaye ngaphantsi kweemitha ezi-5, isakhiwo esixhasayo sixhaswa ngu-φ0.7m * 0.5m umhlaba wesamente ukuxuba imfumba yodonga lokugcina ubunzima. Xa ubunzulu bomgodi wesiseko bukhulu kuneemitha ezi-5 nangaphantsi kweemitha ezili-11, i-φ1.0m*1.2m imfumba ebhorekileyo + umqolo omnye φ0.7m*0.5m isamente yokuxuba umhlaba inkxaso iyasetyenziswa. Ubunzulu bomgodi wesiseko bukhulu kuneemitha ezili-11, usebenzisa i-φ1.2m*1.4m imfumba edikayo + umqolo omnye φ0.7m*0.5m inkxaso yemfumba yesamente yokuxuba umhlaba.
2. Ukubaluleka kolawulo oluthe nkqo
Ulawulo oluthe nkqo lweemfumba lubaluleke kakhulu kulwakhiwo olulandelayo lomngxuma wesiseko. Ukuba ukutenxa nkqo iimfumba ekruqukileyo ejikeleze umngxuma isiseko mkhulu, oko kuya kukhokelela uxinzelelo olungalinganiyo isakhiwo nokugcinwa ngeenxa emhadini isiseko, kwaye kuzisa iingozi ezinkulu ezifihlakeleyo kukhuseleko emhadini isiseko. Kwangaxeshanye, ukuba ukutenxa nkqo kwemfumba ekruqukileyo kukhulu, kuya kuba nefuthe elikhulu kulwakhiwo kunye nokusetyenziswa kwesakhiwo esiphambili kwixesha elizayo. Ngenxa verticality enkulu ukutenxa imfumba ekruqukileyo ejikeleze isakhiwo engundoqo, amandla ajikeleze isakhiwo engundoqo iya kuba ingalingani, nto leyo eya kukhokelela iintanda kwisakhiwo engundoqo, kwaye kuzisa iingozi ezifihlakeleyo ukusetyenziswa elandelayo isakhiwo engundoqo.
3. Isizathu sokutenxa kwe-perpendicularity
Ukutenxa ngokuthe nkqo kwemfumba yovavanyo kukhulu. Ngohlalutyo lweyona projekthi, ezi zizathu zilandelayo zishwankathelwa ukusuka ekukhethweni koomatshini ukuya ekubunjweni komngxuma wokugqibela:
3.1. Ukukhetha amasuntswana e-drill, ubulukhuni bejoloji yomatshini wokumba wemfumba ejikelezayo kwinkqubo yokomba ayifani, ukhetho lwamasuntswana e-drill alukwazi ukuhlangabezana neemfuno zeemeko ezahlukeneyo zejoloji, okubangela ukutenxa kancinci, kwaye ke ukutenxa ngokuthe nkqo imfumba ayihlangabezani neemfuno zeenkcukacha.
3.2. Isilinda sokukhusela singcwatywe ngaphandle kwendawo.
3.3. Ukugxothwa kombhobho wokugrumba kwenzeka ngexesha lokomba.
3.4. Ukubekwa kwendawo yentsimbi yensimbi kuphelile, ngenxa yokumiswa okungafanelekanga kwepadi yokulawula i-cage yensimbi, ukuphambuka okubangelwa ukungaphumeleli ukujonga iziko emva kokuba i-cage yensimbi isendaweni, ukuphambuka okubangelwa ikhonkrithi ekhawulezayo. ukuxuba okanye ukutenxa okubangelwa ngumbhobho ojingayo kwikheji yentsimbi.
4. Amanyathelo olawulo lokutenxa ngokuthe nkqo
4.1. Ukukhetha i-drill bit
Khetha amasuntswana okomba ngokwemiqathango yolwakhiwo:
① Udongwe: khetha umphantsi omnye we-emele yokubhola ejikelezayo, ukuba i-diameter incinci inokusebenzisa ii-emele ezimbini okanye i-emele yokugrumba ipleyiti.
②Intlenga, intlenga yomhlaba obambeneyo ongenamandla, umhlaba onesanti, umaleko wengqalutye ongadityaniswanga kakuhle nobukhulu bamasuntswana amancinane: khetha ibhakethi lokubhola elingaphantsi kabini.
③udongwe oluqinileyo: khetha indawo yokungena enye (ephantsi enye nephindwe kabini inokuba) ibhakethi yokwemba ejikelezayo, okanye amazinyo eemele ethe ngqo.
④igrabile enesamente kunye namatye agutyungelwe ngamandla: kufuneka ixhotyiswe nge-conical spiral drill bit kunye nebhakethi ejikelezayo ejikelezayo ephindwe kabini (enedayamitha enye yobukhulu bamasuntswana amakhulu, enobukhulu obuphindiweyo)
⑤ ibhedi yestroke: ixhotyiswe nge-cylindrical core drill bit - i-conical spiral drill - i-emele yokomba ejikelezayo ephindwe kabini ezantsi, okanye i-spiral drill bit ethe ngqo-ibhakethi yokubhola ejikeleza kabini esezantsi.
⑥Ibhedi evuthelweyo: ixhotyiswe ngecone cone core drill bit – conical spiral drill bit – ibhakethi lokubhola elijikelezayo eliphindwe kabini ezantsi ukuba idiameter inkulu kakhulu ukuba ingathatha inkqubo yokomba.
4.2. Casing wangcwatywa
Ukuze kugcinwe i-verticality ye-cylinder yokukhusela xa kungcwatywa i-cylinder yokukhusela, ulawulo lwe-intersection kufuneka luqhutywe ngomgama ohlukeneyo ukusuka kwimfumba ehamba phambili ukuya kwiziko lemfumba kude kube phezulu kwi-cylinder yokukhusela ifikelele ekuphakameni okuchaziweyo. Emva kokuba i-casing ingcwatywe, indawo esembindini yemfumba ibuyiselwa kunye nalo mgama kunye nesalathiso esinqunywe ngaphambili, kwaye kuchongwa ukuba umbindi we-casing uhambelana nombindi wemfumba, kwaye ulawulwa ngaphakathi koluhlu lwe-± 5cm. . Ngelo xesha, ukujikeleza kwe-casing i-tamped ukuqinisekisa ukuba izinzile kwaye ayiyi kuguqulwa okanye idibanise ngexesha lokugaya.
4.3. Inkqubo yokomba
Ingqumba egrunjiweyo kufuneka igrunjwe kancinane emva kokuvula umngxuma, ukuze yenze ukhuselo olulungileyo noluzinzileyo eludongeni kwaye uqinisekise indawo echanekileyo yomngxuma. Ngethuba lenkqubo yokubhoboza, indawo yombhobho wokubhobhoza ihlolwe rhoqo kunye ne-intersection yomgama, kwaye ukuphambuka kulungelelaniswa ngokukhawuleza kude kube yindawo yokubeka umngxuma.
4.4. Ukuma kwekheji yentsimbi
Ubhaqo lwemfumba yokutenxeka kokuthe nkqo kumiselwa ngokutenxa phakathi kombindi wekheji yentsimbi kunye nombindi wemfumba eyilelwe, ngoko ke ukubekwa kwendawo yentsimbi yinto ebalulekileyo ekulawuleni ukutenxa kwimo yemfumba.
(1) Imivalo emibini yokuxhoma isetyenziselwa xa i-cage yensimbi ifakwe phantsi kokuqinisekisa i-perpendicularity yentsimbi yensimbi emva kokuphakanyiswa.
(2) Ngokweemfuno zekhowudi, i-pad yokukhusela kufuneka yongezwe, ngokukodwa kwi-pile top position kufuneka yongezwe enye ipad yokukhusela.
(3) Emva kokuba i-cage yensimbi ifakwe emngxunyeni, tsala umgca wesiphambano ukuze unqume indawo ephakathi, uze uqhube umgama phakathi kombindi we-intersection kunye nokubuyiswa kwemfumba ngokuzoba imfumba kunye nolwalathiso olumiselweyo. Thelekisa umgca omileyo ojingayo kunye nombindi wekheji yentsimbi, kwaye ulungelelanise ikheji yentsimbi ngokuhambisa kancinane i-crane ukuqinisekisa ukuba amaziko amabini ahambelana, kwaye emva koko weld bar yokubeka ukuze wenze ibha yokumisa ifikelele eludongeni lwesilinda esikhuselayo.
