Problems solved by technology

Due to the large cross-sectional size of the component, the relatively viscous grouting material, and the uneven top surface of the joint, air bubbles will remain on the top surface of the joint, resulting in the grouting joint being not dense and causing defects.

Abstract

The invention discloses a precast segmental prier component horizontal joint grouting and exhausting structure. A prier component comprises an upper component body and a lower component body, and joints are formed among corresponding jointing faces of the upper component body and the lower component body. The precast segmental prier component horizontal joint grouting and exhausting structure is characterized in that one or more exhausting grooves are reserved in the jointing face of the upper component body, the topmost parts of the exhausting grooves are communicated with the outside of theupper component body, during grouting, as the top face of slurry slowly rises, air in the joints is gradually exhausted along the exhausting grooves, and the purpose of compacting grouting joints is achieved. Compared with the prior art, the precast segmental prier component horizontal joint grouting and exhausting structure has the following advantages that after the exhausting grooves are formedin the top faces of the joints, an air exhausting channel in the joint grouting process is added; through reasonable distribution of the exhausting grooves, residual bubbles are greatly reduced, thecompactness of the grouting joints is improved, and the negative influence on a bridge structure is reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge prefabrication and assembly in civil engineering, and in particular relates to a grouting exhaust groove structure suitable for horizontal joints of bridge pier components, in particular to a grouting exhaust structure and a splicing grouting method for horizontal joints of prefabricated assembled bridge pier components. Background technique [0002] When the lower pier of the bridge is constructed by the prefabricated assembly process, there are horizontal joints between the pier column and the cap, between the pier column and the pier column, and between the cap beam and the pier column, and the grouting process is generally used to fill the joints. Due to the large cross-sectional size of the component, the relatively viscous grouting material, and the uneven top surface of the joint, air bubbles will remain on the top surface of the joint, resulting in the grouting joint being not dense and caus...
