CAST-IN-PLACE PILE Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this can be used in construction of gravel- and sand-filled piles, in construction of cast-in-place posts of any diameter for bridge building and civil engineering. Pile has framework, concrete body with fortified base. Head-piece is secured on pile base. Framework is provided with stiffening ring which is rigidly secured in upper part of framework. Fortified base is rigidly connected with framework. Head-piece is located inside fortified base. Application of aforesaid arrangement allows for reaching high load-bearing capacity of structure, improved water-impermeability and frost-resistance of pile concrete. It allows for increasing load-bearing capacity at pad and ensures mounting of reinforcement framework strictly along axis. EFFECT: higher efficiency. 3 cl, 2 dwg
