Abstract

The invention discloses a high-strength concrete prefabricated pile doped with a fiber-reinforced plastic bar, which comprises a steel reinforcement cage framework. The high-strength concrete prefabricated pile is characterized in the fiber-reinforced plastic bar is arranged in the steel reinforcement cage framework; end plates are respectively arranged at two ends of the steel reinforcement cage framework; concrete is cast on the steel reinforcement cage framework and the fiber-reinforced plastic bar, so that the steel reinforcement cage framework, the fiber-reinforced plastic bar and the end plates are integrated; and a central round hole penetrating through the whole pipe body is formed in the middle of the integrated pile body. The invention aims at overcoming the defects in the prior art and providing the high-strength concrete prefabricated pile doped with the fiber-reinforced plastic bar, which has the advantages of favorable horizontal bending resistant bearing capacity, high pullout-resistant bearing capacity, high single-pile vertical bearing capacity, strong anti-seismic capability and suitability for projects having higher requirements for bending resistance and pullout resistance.

Description

technical field [0001] The invention relates to a high-strength concrete prefabricated pile mixed with fiber-reinforced plastic bars. Background technique [0002] With the improvement of the importance of modern buildings and the continuous increase of building height, higher requirements are put forward for the bearing capacity of the foundation. The natural foundation can no longer bear the load from the upper building. At present, reinforced concrete is used as the The foundation piles of the foundation are formed by pressing the piles into the ground with a pile driver to allow the upper part of the foundation piles to carry the building. Among them, the stress concrete pile is more prominent, and is widely used in the construction of buildings, roads, docks and other foundation projects due to its superior performance. The structure of prestressed concrete prefabricated piles produced and sold on the market is mainly composed of a prestressed steel cage skeleton, two ...
