High strength pre-stressed concrete pipe pile and preparation method thereof

Abstract

The invention relates to a high strength pre-stressed concrete pipe pile, which comprises cement, mineral slag, iron tailing, fly ash, silicon carbide, lime, sodium carbonate, broken stone, tartaric acid, early strong agent, and water reducer. The pipe pile is prepared by the following steps: weighing the components mentioned above, adding water, evenly stirring, casting the mixture into a mould, carrying out centrifugal moulding, and finally performing steam curing under a normal pressure to obtain the finished product. The components cooperate with each other to generate a synergetic effect, the strength of finished product is larger than 100 Mpa, moreover, the cost is proper, the production technology is simple and convenient, the curing is carried out without high pressure, the energy is saved, and the total production cost is reduced.

Description

technical field [0001] The invention belongs to concrete pipe pile structure field , especially a high-strength prestressed concrete pipe pile and a preparation method thereof. Background technique [0002] Concrete is a kind of artificial stone made of cementitious materials, granular aggregates, water and necessary admixtures in a certain proportion, uniformly stirred, compacted, cured and hardened. The process is simple, but the concrete produced has high compressive strength and good durability, and is widely used in many fields. The underground drainage pipe is made of concrete. The main materials are cement, sand, gravel and additives. Add water to the various materials and mix them evenly. Put them into the mold and let them stand. Among them, the formulas of various manufacturers are relatively chaotic. Some manufacturers increase the addition of certain components in order to improve a certain performance, which not only increases the production cost, but also has...

AI Technical Summary

Problems solved by technology

The underground drainage pipe is made of concrete, and the main materials are cement, sand, gravel and additives. After adding water, the various materials are mixed evenly, put into the mold and left to stand, and after demolding, the finished product is made by high-pressure steam curing, and processed by traditional methods Among them, the formulas of various manufacturers are relatively chaotic. Some manufacturers increase the addition of certain components in order to improve a certain performance, which not only increases the production cost, but also has the possibility of further improving the performance of pipe piles.
