Abstract

The invention discloses a fully prestressed concrete solidly hammered picket-free square pile, relating to the field of construction and building materials. The fully prestressed concrete solidly hammered picket-free square pile comprises a pile body, wherein the pile body is wound with prestressed main reinforcements by virtue of a spiral stirrup, the spiral stirrup is bound and connected with the junction of the main reinforcements at intervals; the end part of the fully prestressed concrete solidly hammered picket-free square pile is provided with a reinforcing rib; and the fully prestressed concrete solidly hammered picket-free square pile is obtained by adopting one piece casting of concrete. The end part of the square pile is additionally provided with a reinforcing rib, a supporting layer can be easily reached when the pile is sunk, the completeness of the pile body and end resistance are high, and the vertical bearing capacity of a single pile is improved. Besides, the square pile adopts a solid picket-free concrete structure, the construction stability of the square pile is higher, and the structural and mechanical performances of the square pile can meet the design requirements, thus being beneficial to field operation.

Description

technical field [0001] The invention relates to the construction field of building materials, in particular to a fully prestressed concrete solid hammered square pile without pile tip. Background technique [0002] In the existing technical standard full prestressed hollow pipe pile, during the construction process, when the end is hammered, it is very easy to break, and the hammering cannot be continued, thereby affecting the construction. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned technical problems, and to provide a fully prestressed concrete solid hammered square pile without a pile tip, which is hammer-resistant and high-end resistance. [0004] In order to achieve the above object, the present invention adopts the technical scheme as follows: provide a fully prestressed concrete solid hammered square pile without a pile tip, the fully prestressed concrete solid hammered square pile with...
