Partially-prestressed reinforced concrete solid square pile upper segment and manufacturing method thereof

Abstract

The invention provides a partially-prestressed reinforced concrete solid square pile upper segment and a manufacturing method thereof. The partially-prestressed reinforced concrete solid square pile upper segment and the manufacturing method thereof are used for solving the problems that in the prior art, in the process of pile cutting of an upper segment of a prefabricated pile, a pile body is damaged, or pile cutting is not convenient, so that the phenomenon that the pile body can not meet requirements for mechanical performance and pile sinking construction is caused. The upper segment of the square pile comprises concrete, a reinforcement cage, a pile cap and a fixed end plate, wherein the reinforcement cage is of a square combined type whole structure, the pile cap is arranged at one end of the reinforcement cage and fixedly connected with the reinforcement cage, and the fixed end plate is arranged at the other end of the reinforcement cage and is fixedly connected with the reinforcement cage. By the adoption of the technical scheme, the square pile upper segment facilitates pile cutting under the premise that the pile body is not damaged, is beneficial to improving mechanical performance of the upper segment of the prefabricated pile, and improves bearing force of tension of the pile body.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an upper part of a partially prestressed reinforced concrete solid square pile and a manufacturing method thereof. Background technique [0002] Prestressed high-strength concrete pipe piles have the characteristics of high vertical bearing capacity, high effective precompressed stress of pile concrete, good crack resistance of pile concrete and impact resistance in pile sinking; in addition, its special hollow structure design, special steel The main reinforcement adopts prestressed spiral grooved steel bars with a tensile strength of not less than 1420MPa and a non-proportional elongation strength of not less than 1280MPa. The application of a mature automatic production line endows the pipe pile with less raw material consumption, high production efficiency and low cost. specialty. Therefore, currently cost-effective pipe piles are widely used. [0003] However, the geologi...
