Supporting disc type prestressed concrete pile

Abstract

The invention discloses a supporting disc type prestressed concrete pile. The supporting disc type prestressed concrete pile comprises a plurality of sections of connected pile bodies, supporting discs are arranged in the vertical direction of the pile bodies at intervals, the supporting discs protrude out of the pile bodies, the adjacent supporting disc type prestressed concrete piles are connected through pile connectors, each pile connector comprises a pile hoop and a pile end plate, and the pile end plates of the adjacent supporting disc type prestressed concrete piles are connected. According to the supporting disc type prestressed concrete pile, the supporting discs protruding out of the pile bodies are arranged between the pile bodies, the contact area of the side face of the supporting disc type prestressed concrete pile and a soil body is increased through the supporting discs, the side friction resistance of the supporting disc type prestressed concrete pile is improved, a certain end resistance can be provided, and therefore the bearing capacity of the supporting disc type prestressed concrete pile is improved, and meanwhile, the locally-protruding supporting discs can play a certain role in compacting and compacting the soil body below the supporting discs in the pile sinking process, the vertical bearing capacity of the supporting disc type prestressed concrete pile is improved, and meanwhile sedimentation of the supporting disc type prestressed concrete pile under the vertical load is reduced.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete prefabricated products for buildings, in particular to a disc type prestressed concrete pile. Background technique [0002] Prestressed concrete piles are widely used in foundation engineering, and have the characteristics of high bearing capacity, convenient manufacture, simple mold, and strong corrosion resistance. Prestressed concrete piles can be used in large or important buildings as the substructure to transfer the load of the building to the soil bearing layer or a harder site to increase the safety and stability of the building structure. [0003] Since prestressed concrete piles are mostly prefabricated in factories, when the length of a single prestressed concrete pile is limited, in the prior art, multi-section prestressed concrete piles are connected to ensure that the prestressed concrete piles However, in the prior art, the structural strength of the joints of multi-sec...

[0003] Since prestressed concrete piles are mostly prefabricated in factories, when the length of a single prestressed concrete pile is limited, in the prior art, multi-section prestressed concrete piles are connected to ensure that the prestressed concrete piles However, in the prior art, the structural strength of the joints of multi-section prestressed concrete piles is poor, which reduces the bearing capacity of prestressed concrete piles
