A corrosion-resistant phc pipe pile

Abstract

The invention discloses a corrosion-resistant PHC pipe pile. The corrosion-resistant PHC pipe pile is characterized by comprising the following components in parts by weight: 1 part of a binding material, 0.28 part of water, 1.58 parts of sand, 2.92 parts of stones, 0.023 part of a water reducer, 0.005-0.03 part of an organic corrosion inhibitor HQ; and the organic corrosion inhibitor HQ accounts for 0.5%-3% of weight of the binding material. The corrosion-resistant PHC pipe pile has the advantages that (1) the technologic processes of an existing pipe pile do no need to be changed, and no production equipment is added; (2) production process parameters of the existing pipe pile do not need to be changed; (3) the production cost is low; and (4) an existing pipe pile production line can be used for producing national standard of PHC pipe piles, and can also be used for producing the corrosion-resistant PHC pipe pile.

Description

technical field

[0001] The invention relates to a pretensioned prestressed concrete pipe pile, in particular to a corrosion-resistant PHC pipe pile. Background technique

[0002] Due to the existence of corrosive geological conditions, especially in coastal areas, Cl-corrosive geological conditions in seawater are relatively common, and engineering requires the corrosion resistance of concrete pipe piles.

[0003] For the corrosion resistance of pipe piles, the main method currently used is: mixing finely ground slag, finely ground fly ash, etc., to reduce the content of CaO in concrete, so as to reduce the corrosion of Cl- on pipe pile concrete. This production method has a complicated process, and needs to increase storage tanks and metering equipment for grinding fine slag and grinding fly ash. Contents of the invention

[0004] The object of the present invention is to provide a corrosion-resistant PHC pipe pile, which can be used in corrosive geological conditions, e...
