Segmentation prefabricating sunken outer wall and guide wall thereof

摘要: The utility model discloses a segmentation prefabricating sunken outer wall which has reinforced concrete prestress structure. A vertical rotary spray through hole is reserved in the center of body; bottom foot body slightly wider than an inner layer and main reinforcements inside outside adopt steel wires (all or partial); pass thin-walled pipes; parts pipes on side are communicated with each other; periphery wire pipe cast protective layer; locked upper end surface anchorage device; reinforcement connector pre-embedded body. characterized that semicircle guide grooves formed at two ends convex head arranged lower deformation observation stress meter can maximize construction safety convenience, further reduce cost.
