Hydraulic rock drilling rig

The Full Casing Drill is generally equipped with hydraulically driven holding, shaking, pressing and pulling mechanisms. 

The drilling process is to use a hydraulic system to push the casing directly into the soil, or to shake when the soil is pressed into the soil,

 and use a hammer grab to extract the soil from the casing. The grab is inserted into the earth with its own weight, and

 the grab flaps are closed with steel cables. The special single rope grab can complete the process of swinging outward, opening valve unloading,

 resetting, opening valve unloading during lifting. After the hole is formed, while pouring underwater concrete, the casing is pulled out section by section and

 removed, and finally the casing is completely removed.
