15 results about "Parent rock" patented technology

Parent rock, also referred to as substratum, refers to the original rock from which something else was formed. It is mainly used in the context of soil formation where the parent rock (or parent material) normally has a large influence on the nature of the resulting soil. For example,clay soil is derived from shale while sandy soil comes from the weathering of sandstones. The term is also used in the context of metamorphic rocks where again the parent rock or protolith refers to the original rock before metamorphism takes place. Parent rocks can be sedimentary, igneous or metamorphic.

A grouting reinforcement device for unstable rock masses in mines

This invention provides a grouting reinforcement device for unstable rock masses in mines. Compared with existing technologies, vertical grouting grooves are opened at the top of both the secondary unstable rock and the parent rock, and an inclined grouting groove is opened at the bottom of the secondary unstable rock. Vertical and inclined insertion tubes are inserted into the vertical and inclined grouting grooves, respectively. The studs at the bottom of the vertical insertion tubes can be locked with the screw holes of the inclined insertion tubes, thereby locking the three insertion tubes in the secondary unstable rock and the parent rock. A secondary locking connection is made through the internal insertion columns and inclined rods to enhance the stability after connection and cope with the prestress of the secondary unstable rock. Concrete grout is added into the vertical and inclined grouting grooves through the grouting holes on the surface of the vertical and inclined insertion tubes. After solidification, the outer ends of the secondary unstable rock and the parent rock are locked by external fixing components. Anchor ropes are wrapped around the fixing rings at the top of the vertical and inclined insertion tubes to further strengthen the prestress of the secondary unstable rock from the outside.
