Problems solved by technology

[0004] However, in the actual use of concrete pipe piles, since the pipe piles are often buried deep in the ground, the chloride ions and sulfate ions in the soil will cause corrosion on the surface and inside of the pipe piles. It affects the structural strength and service life of pipe piles, and even causes the collapse of buildings, bridges, etc., causing serious accidents and posing a great threat to people's lives and property

Abstract

The invention relates to a steam-curing-free high-strength anti-corrosion pipe pile and a preparation method thereof, and belongs to the technical field of pile foundations. The steam-curing-free high-strength anti-corrosion pipe pile comprises 250 to 320 parts of cement, 1000 to 1200 parts of fine aggregate, 1300 to 1500 parts of coarse aggregate, 120 to 210 parts of water, 40 to 60 parts of fly ash, 50 to 70 parts of mineral powder, 6.5 to 8.5 parts of a water reducing agent, 20 to 25 parts of nano calcium carbonate, 0.12 to 0.2 part of sodium hexametaphosphate, 2 to 5 parts of chitosan modified basalt fiber and 10 to 18 parts of polydimethylsiloxane. The preparation method comprises the following steps: uniformly mixing the components to obtain concrete slurry; feeding the obtained concrete slurry into a pipe pile mold with a reinforcement cage, and performing centrifugal forming; hoisting the centrifuged pipe pile mold into a normal-pressure maintenance pool for maintenance; and demolding after curing to obtain the pipe pile. The corrosion-resistant pipe pile has the effect of improving the corrosion resistance of the pipe pile, so that the durability of the pipe pile is improved.

Description

technical field [0001] The present application relates to the field of pipe piles, in particular to a non-steam curing high-strength anti-corrosion pipe pile and a preparation method thereof. Background technique [0002] The foundation refers to the load-bearing structure below the ground of the building. It is the enlarged part of the wall or column of the building underground. Its function is to bear the load transmitted from the upper structure of the building and transmit them to the foundation together with its own weight. [0003] At present, the utilization rate of pile foundation in foundation engineering exceeds 90%, and it is one of the commonly used foundation forms. The pile foundation is composed of two parts: a plurality of piles buried in the foundation (called pile group) and a pile platform (called cap) that combines the pile group to work together; the function of the pile foundation is to transmit the load to the ground The deep soil layer with good bear...
