Embodiment Construction
[0026] combine figure 1 and figure 2 , a prefabricated reinforced concrete square pile, comprising a reinforcement cage, a pile tip assembly, a pile end mesh and high-strength concrete. The main bar 1 of the reinforcement cage is made of HRB400 steel bar. The reinforcement cage is made by sliding and welding the main bar 1 through the stirrup 2 in a spiral shape. The section (structure) of the reinforcement cage is a regular quadrilateral. The above-mentioned pile end mesh 3, steel cage, and pile tip components form an overall skeleton, and the overall skeleton and high-strength concrete form a whole solid pile body, and the whole solid pile body is composed of a pile main section and a pile tip section, and the section of the pile main section It is square, and the pile tip section is square cone-shaped.
[0027] Preferably, the above-mentioned reinforcement cage is made of 8 main reinforcements through spiral sliding seam welding of stirrups.
[0028] Preferably, the thi...

Abstract
The invention discloses a precast reinforced concrete square pile and a manufacturing method thereof. The square pile comprises a reinforcement cage, a pile toe assembly, a pile tip mesh and high-strength concrete, wherein HRB400 reinforcement is adopted as main reinforcement of the reinforcement cage; the reinforcement cage is formed by the main reinforcement manufactured by welding stirrups in a spiral sliding manner; the section of the reinforcement cage is a regular quadrangle; the pile tip mesh, the reinforcement cage and the pile toe assembly form a whole framework; the whole framework and the high-strength concrete form a whole solid pile body; the whole solid pile body is formed by a pile body section and a pile toe section; and the section of the pile body section is square, and the section of the pile toe section is pyramidal. In the invention, as the pile equipped reinforcement cage is formed by mechanical roll welding, the usage amount of the stirrups can be reduced; the square pile has the advantages of advanced process, convenience in operation, reliable quality and high production efficiency; and besides, the whole strength of the pile can be improved by adopting the high-strength concrete for pouring.
Description
technical field [0001] The invention relates to the field of production and processing of building materials, in particular to a prefabricated reinforced concrete square pile and a method for manufacturing the prefabricated reinforced concrete square pile. Background technique [0002] According to the existing pile foundation design, in the production process of ordinary reinforced concrete piles, prefabricated steel cages are used to bind the stirrups densely, and the main reinforcement is tied to the hoops. become. The production process of the above-mentioned concrete piles is complicated and old, and the production of steel cages is time-consuming and labor-intensive, the labor intensity is high, the quality is poor, and the production cost of the concrete piles is increased. [0003] This shows that it is necessary to improve the prefabricated reinforced concrete pile body and its manufacturing method in the prior art. Contents of the invention [0004] The task of...
