The utility model discloses a prefabricated shear wall aluminum mould hole filling and plugging device, including the plugging plug and the grouting plug, install respectively in the both sides of shear wall aluminum mould hole, the grouting plug is circular table shape structure, and the inside coaxial opening has the cylinder cavity, install the piston disc of disc shape in the cylinder cavity, still have the guide rod fixedly in the cylinder cavity, the piston disc central opening has the perforation, is used for the axle position movement adjustment of bushing guide rod, and the cylinder cavity corresponds the limit device of guide rod end. Simple structure, easy to make and low cost, convenient operation, just need to plugging the both ends of prefabricated shear wall can start grouting filling, simple construction, construction quality controllable, guarantee plugging dense, save material cost and labor cost, reduce the later repair expense, guarantee construction quality and realize the project cost reduction and benefit increase at the same time, convenient to use, safe and reliable can improve construction efficiency and quality greatly.

This invention discloses a composite bridge pier suitable for high-altitude and cold regions, comprising an inner core and an outer ring. The outer ring encloses the inner core and is made of ultra-high-strength concrete. The inner core is cast on-site from ordinary concrete, while the outer ring is prefabricated in a factory. This composite bridge pier uses only the more expensive ultra-high-strength concrete in the outer ring, which meets the requirements for freeze-thaw resistance while reducing the amount of ultra-high-strength concrete used, thus balancing project costs. Furthermore, the prefabricated outer ring can be directly used as a formwork for the bridge pier on-site, eliminating the material costs and installation / disassembly costs associated with traditional formwork construction.
