The invention discloses a high-strength precast concrete pile and a pouring technology thereof, and belongs to the technical field of concrete pile preparation. A pile hole attachment cage and an inner reinforcement body are arranged on the inner and outer sides of a reinforcing cage, the pile hole attachment cage formed by an annular steel cage and a conical embedment steel plate is embedded in apile hole, a first pouring cavity formed therebetween is filled with a first concrete layer, and a strong outer reinforcement layer is formed outside the reinforcing cage; then the reinforcing cage is inserted into the pile hole attachment cage, and a second concrete layer fills between the reinforcing cage and the pile hole attachment cage to achieve mechanical bonding therebetween; then the inner reinforcement body is placed in the reinforcing cage, the inner reinforcement body comprises a hollow injection steel pipe located in the middle and a plurality of fan-shaped reinforcement pieces distributed on the outer side of the hollow injection steel pipe, and a third concrete layer fills between each two fan-shaped reinforcement pieces; according to the pouring technology of inserting filling layer by layer from outside to inside, on the one hand, the concrete pile is not liable to scatter, and on the other hand, the bearing capacity and pull-out resistance of a solid square pile areeffectively improved.
Description
technical field [0001] The invention relates to the technical field of concrete pile preparation, in particular to a high-strength prefabricated concrete pile and its pouring process. Background technique [0002] In the modern construction industry, foundations and piles are one of the most important parts of construction. Concrete piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete), which have the advantages of saving wood and steel, durable, and low cost. , has been widely used in the foundation engineering of hydraulic construction, industrial construction, civil construction and bridges, and is also commonly used in anti-skid or water isolation of slope and foundation pit support. [0003] The cross-section of the pile is square, rectangular, circular, etc., and the most commonly used ones are square cross-section piles and circular cross-section piles. Put it into the pile hole, pour concrete, and form a concrete pile aft...
