Rotary drilling rig rudzi rwemuchina wekuvaka wakakodzera kushanda mukugadzira maburi mukuvaka foundation engineering. Inonyanya kukodzera kuvaka jecha, ivhu, ivhu rine silty nedzimwe ivhu, uye yakashandiswa zvakanyanya mukuvaka foundation dzakasiyana-siyana dzakadai sema cast-in-place piles, diaphragm walls, uye foundation reinforcement. Simba re rotary drilling rig rinowanzova 117 ~ 450KW, simba rinobuda simba i45 ~ 600kN · m, dhayamita yepamusoro yegomba inogona kusvika 1 ~ 4m, uye kudzika kwegomba kwakanyanya i15 ~ 150m, izvo zvinogona kusangana nezvinodiwa zvekuvaka foundation yakakura.
Rotary drilling rig inowanzo shandisa hydraulic crawler telescopic chassis, self-lifting and landing foldable mast, telescopic kelly bar, ine otomatiki perpendicularity detection uye adjustment, maburi edhijitari display, nezvimwewo. Kushanda kwemuchina wese kunowanzo shandisa hydraulic pilot control uye load sensing. Zviri nyore uye zvinonyaradza kushanda.
Chikwindi chikuru nechinhu chekubatsira chinogona kushandiswa mumamiriro akasiyana-siyana panzvimbo yekuvaka. Pamwe chete nezvishandiso zvakasiyana-siyana zvekuboorera, gomba rekuboorera rakakodzera mabasa akaoma (short auger) kana akanyorova (rotary bucket) uye dombo (core barrel). Rinogonawo kuiswa nechinhu che "long auger", "diaphragm wall grab", "vibrating pile hammer", nezvimwewo kuti zviite mabasa akasiyana-siyana. Rinonyanya kushandiswa mukuvaka maguta, mabhiriji emigwagwa, zvivakwa zvemaindasitiri nezvehurumende, madziro epasi pevhu, kuchengetedza mvura, kudzivirira kuyerera kwemvura uye kudzivirira maromo uye dzimwe nzvimbo dzekuvaka.
Kushandiswa kwemuchina mudiki wekuboorera unotenderera:
(1) Mirwi yekudzivirira materu ezvivakwa zvakasiyana-siyana;
(2) Chikamu chemirwi yezvivako zvinotakura mutoro zvechivako;
(3) Mapombi akasiyana-siyana ane dhayamita isingasviki 1m ezvirongwa zvekugadzirisa maguta emaguta;
(4) Dururirai zvimwe zvinangwa.
