Isu tinogadzira emhando yepamusoro hupenyu hurefu hweconical tapered drill pombi uye tapered drill tsvimbo muhurefu hwakasiyana.

Tapered drill rods imhando yemidziyo yekuchera inoshandiswa mumabasa akasiyana ekuchera, kunyanya mumigodhi nekuvaka.Aya matanda anogadzirwa kubva kumhando yepamusoro simbi uye anogadzirwa achishandisa hunyanzvi hwekugadzirisa maitiro senge kupisa kupisa uye kutonhora kushanda.

Kubatsira kukuru kwetapered drill rods ndeyokuti dzakagadzirwa kuti dzibatane pamwe chete kuitira kuti dzigadzire tambo yekuchera iyo inogona kusvika pakadzika pasi kana padombo.Izvi zvinoreva kuti dzakakwana pakuchera makomba munzvimbo dzakaoma, dzakaoma-kusvika, dzakadai semigodhi yepasi pevhu kana tunnel.

Imwe mukana weiyo tapered drill rods ndeyekuti inogara yakasimba uye inogona kumira kushushikana uye kuomarara kwekuenderera mberi kwekuchera.Iwo zvakare ari nyore kushandisa uye anogona kukurumidza kuunganidzwa uye kuparadzaniswa, izvo zvinoita kuti ive yakakodzera kushandiswa munzvimbo dziri kure kana dzakaoma-kusvika.

Chekupedzisira, tapered drill rods inopa yakanakisa kucheka mashandiro uye akagadzirwa kuti ave akasiyana-siyana, zvinoreva kuti anogona kushandiswa kune dzakasiyana siyana dzekuchera, kusanganisira kudhirowa kwedombo, sampling yevhu, uye geotechnical drilling.Pakazere, tapered drill rods chishandiso chakavimbika uye chinoshanda icho chakakosha kumabasa mazhinji ekuchera.
