PRE-CAST REINFORCED CONCRETE RETAINING WALL Russian patent published in 1996 - IPC

FIELD: civil engineering. SUBSTANCE: pre-cast reinforced concrete wall has face slabs, abutments, anchors and foundation. The foundation is made in the form of raft foundation of crossed strips. And face slabs are fixed over three sides by bringing lateral faces into the slots of pre-cast abutments and lower face into the slot made in monolithic reinforced concrete foundation mat. Rare strips of raft foundation are provided with steps for fixing the anchors by their lower parts using cylindrical hinges. The raft foundation may use concurrently both prismatic and bored piles, arranged in both stagged order and in the form of a cluster of three piles each placed under the abutments. EFFECT: anchoring abutments and fixing face slabs over three sides allows to improve efficiency of the proposed pre-cast reinforced retaining wall and decrease consumption of metal for reinforcing face slabs as compared to reinforcing slabs as corner-type reinforcing walls and abutments with face slabs, as a rule, rests on two sides. 3 dwg
