Description
Technical field
The utility model relates to a kind of compound square pile, relates in particular to corrosion-resistant compound square pile for a kind of civil engineering.
Background technology
China is vast in territory, marine environment is different and weather is various, as damp and hot, the carbonization of the southeastern coastal areas and chlorine salt corrosion, freeze thawing, carbonization and the chlorine salt corrosion of Northern Coastal Provinces, dry and cold, xeothermic, the villaumite of western Salt Lake Area and sulphate corrosion, these all make the mode of failure of precast concrete general, various and complicated.
Existing square pile anti-corrosion measure is that concrete proportioning is changed, and this change need to be carried out a large amount of experimental studies, and the cycle is very long, reasearch funds are also higher, and corrosion resistant concrete price is higher and effect is not very good, in addition, the anti-wear performance of square pile is poor.Therefore, provide wear-resisting compound square pile of a kind of corrosion-resistant while to become those skilled in the art's problem demanding prompt solution.
Utility model content
One of the purpose of this utility model is in order to overcome deficiency of the prior art, and wear-resisting compound square pile of corrosion-resistant while for a kind of civil engineering is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of corrosion-resistant compound square pile for civil engineering, comprises pile body,
The cross section of described pile body is square, and the below of described pile body is provided with prefabricated sagittate pile crown, and described pile body inside is evenly provided with several prestressed reinforcements, and described prestressed reinforcement outer ring is wound with a steel mesh reinforcement;
The inwall of described pile body is provided with interior anticorrosive coat, and the outer wall of described pile body is provided with external anti-corrosion layer, and the outside of described external anti-corrosion layer is also provided with a wearing layer.
Preferably, described external anti-corrosion layer and wearing layer are formed in one.
Preferably, described steel mesh reinforcement is equidistant formula and is looped around on prestressed reinforcement.
Preferably, described prestressed reinforcement is 8.
Preferably, described steel mesh reinforcement around the adjustable setting of gradient.
Preferably, the diameter of described prestressed reinforcement is four times of steel mesh reinforcement diameter.
