A kind of anti-corrosion concrete prefabricated square pile with directional capillary water seepage function

Abstract

The invention discloses a corrosion-resistant concrete prefabricated square pile with directional capillary water seepage function, which belongs to the field of concrete square piles. A reinforcement cage with a reinforcement mechanism, the reinforcement cage plays the role of supporting the concrete layer, and the reinforcement cage is fixedly connected with a fixed reinforcement column through the reinforcement mechanism. Further strengthen the mechanical strength of the concrete layer and improve the deformation resistance of the concrete layer. On the other hand, it is beneficial to the fixed connection between the two adjacent piles up and down. The water seepage layer, on the one hand, effectively prevents external moisture from penetrating into the concrete prefabricated square pile, and on the other hand, facilitates the directional flow of moisture from the outer end of the square pile, improving the waterproof, anti-penetration and anti-corrosion properties of the square pile.

Description

technical field [0001] The invention relates to the field of concrete prefabricated square piles, in particular to a corrosion-resistant concrete prefabricated square pile with directional capillary water seepage function. Background technique [0002] The prefabricated concrete square pile is based on the combination of concrete and steel bars to form a concrete square pile steel structure. The existing concrete prefabricated square pile will have a reinforcement cage inside, and the main reinforcement of the skeleton is evenly distributed in the reinforcement cage. The shape of the pile body is square, and the pile center is a cylinder. When the square pile is formed, the concrete is poured to form a concrete layer. The high impermeability and water resistance of concrete is an important qualification index for construction engineering. [0003] If the permeability of the concrete itself is serious, the concrete body will be arched, cracked, loose and leaky, the mortar wi...

[0003] If the permeability of the concrete itself is serious, the concrete body will arch, crack, loose and leak, the mortar will fall off or even be damaged, which will reduce the durability of the square pile

At the same time, when a large amount of water seeps into the concrete, it will cause corrosion of the internal steel bars. When the volume of the steel bars corrodes and expands to a certain extent, it will further lead to cracking of the concrete. After the concrete cracks, the corrosion of the steel bars will be accelerated, which in turn will accelerate the concrete. Destruction seriously causes longitudinal cracks and cracks in the concrete along the direction of the steel bar, seriously weakens the tensile capacity of the steel bar, and the stress section becomes smaller after the steel bar corrodes, which seriously endangers the stress safety of the structure and leads to huge economic losses. losses and major personnel safety accidents
