Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0029] A kind of production method of pretensioned prestressed concrete dynamic load pile of the present invention comprises the following steps:

[0030] A, a plurality of prestressed reinforcing bars 8 are arranged circularly, and then a spiral rib 7 is welded outside the described plurality of prestressed reinforced bars 8 to form a prestressed reinforcing bar skeleton cage 2; a plurality of non-prestressed reinforcing bars 6 are arranged in a circular manner, Then a spiral rib 7 is welded on the outside of the plurality of non-prestressed steel bars 6 to form a non-prestressed steel bar skeleton cage 1, and the non-prestressed steel bar skeleton cage 1 is installed in the prestressed steel bar skeleton cage 2;

[0031] B. Clean up the corresponding steel mold and apply release agent;

[0032] C, hang the double-layer reinforcement sk...

Abstract

The invention discloses a production method of pretensioning prestressed concrete dynamic load piles, comprising the following steps: arranging a welded non-prestressed steel reinforcement framework cage in a prestressed steel reinforcement cage; cleaning a corresponding steel die; coating a separant; suspending the double-layer steel reinforcement framework cage in a lower die body of the steel die; respectively arranging the end plates of a connected hooping plate at the two ends of the double-layer steel reinforcement framework cage; casting concrete material to the lower die body of the steel die; carrying out die assembly and pre-stressed tensioning; performing centrifugal shaping; pouring out the surplus starch solution on the inner wall; and carrying out steam curing and secondary steam curing. The production method provided by the invention aims to overcome the shortages in the prior art. The invention provides a method for producing a pretensioning prestressed concrete dynamic load dynamic load pile with horizontal anti-bending bearing capacity, high shearing resistance, high bearing capacity of a single pile, and strong shock resistance.

Description

technical field [0001] The invention relates to a production method of a pretensioned prestressed concrete dynamic load pile. Background technique [0002] Prestressed concrete pipe piles are widely used in the construction of buildings, roads, docks and other foundation projects due to their superior performance. The structure of prestressed concrete pipe piles produced and sold on the market is mainly composed of a prestressed steel skeleton cage, two end plates, two hoop plates and concrete, and its characteristics are mainly designed to meet the requirements of vertical bearing , without considering the effect of its horizontal load, especially the effect of dynamic load level. Therefore, the prestressed concrete pipe piles produced by existing production methods have poor horizontal flexural bearing capacity and high brittleness, especially in traffic fields such as bridges, and it is difficult to meet the requirements of design and actual use in terms of dynamic load....
