Post-pressure-grouting structure of steel-concrete combined section
The invention discloses a post-pressure-grouting structure of a steel-concrete combined section. The post-pressure-grouting structure comprises an outer face plate, laid on a concrete base, of the steel-concrete combined section. An inner face plate of the steel-concrete combined section is laid in the outer face plate and surrounds the outer face plate. A plurality of face plate middle grooves are formed in the portion defined by the inner face plate, the outer face plate and vertical rib plates. Water draining holes are formed in the side wall of the lower end of the outer face plate, and air exhausting holes are formed in the side wall of the upper end of the outer face plate. Corrugated pipes for steel strands to penetrate through are reserved in the concrete base. The corrugated pipes on the concrete base penetrate through the face plate middle grooves and extend out of steel strand reserved holes in a load bearing plate, and the face plate middle grooves are poured with polyethylene fiber concrete and self-leveling mortar layers. Mortar pressing holes are formed in the lower end of the load bearing plate, the multiple steel strand reserved holes are evenly formed in the portion, on the periphery of a load bearing plate middle groove, of the load bearing plate and sealed with silica cement, and a plurality of load-bearing-plate air exhausting holes are formed in the portion, on the periphery of the load bearing plate middle groove, of the load bearing plate. According to the post-pressure-grouting structure, pouring compactness and pouring strength are improved.
