Problems solved by technology

However, in the current market, its bearing capacity is determined by the friction between the surface area of ​​the pipe pile and the soil. If the friction between the soil is small and cannot meet the bearing capacity requirements, the only way to increase the length of the pipe pile or increase the number of pipe piles is to Make the pipe pile reach the bearing capacity required by the design, which will inevitably increase the cost and difficulty of the pile foundation project

Embodiment 1

[0023] A concrete pipe pile for road and bridge, comprising a circular steel pipe and an organic coating layer coated with an organic paint on the outer wall of the circular steel pipe, the inner wall of the steel pipe is welded with a cross-reinforced beam, and the inside of the steel pipe is filled with concrete,

[0024] The chemical element composition of the round steel pipe is (weight percent): C: 0.22%, Mg: 4.1%, Mo: 2.3%,: Cr 2.1%, Mn: 0.72%, Sn: 0.63%, Bi: 0.54%, Nb: 0.34 ﹪, Ag: 0.13%, Ti: 0.073%, V: 0.052%, Sb: 0.031%, Zn: 0.022%, Pd: 0.024%, and the balance is Fe and unavoidable impurities;

[0025] The preparation method of the round steel pipe includes the following steps: according to the composition and ingredients of the above round steel pipe elements, the pure iron is first added to the smelting furnace, and the furnace temperature is controlled at 1450 ° C. After the pure iron is melted, the furnace temperature drops to 1440 ° C and added Magnesium-iron mast...

Abstract

A road and bridge construction concrete pile tube comprises a round steel pipe and an organic coating layer coated on the outer wall of the round steel pipe; a cross-shaped rib is welded on the inner wall of the steel pipe, and the steel pipe is filled by concrete; the concrete is formed by using a plurality of blended materials, so the compressive strength can reach the following level: 7d:33MPa; 28d: 50MPa. The cross-shaped rib can provide good product structure performance, thus improving product intensity; the organic coating can provide steel pipe external corrosion resisting performance.

Description

technical field [0001] The invention relates to a concrete pipe pile for road and bridge, and belongs to the technical field of road and bridge construction. Background technique [0002] The foundation engineering of most buildings adopts driving or pressing concrete pipe piles, so as to improve the bearing capacity of the foundation and ensure the safety of the building. However, in the current market, its bearing capacity is determined by the friction between the surface area of ​​the pipe pile and the soil. If the friction between the soil is small and cannot meet the bearing capacity requirements, the only way to increase the length of the pipe pile or increase the number of pipe piles is to To make the pipe pile reach the bearing capacity required by the design, this will inevitably increase the cost and difficulty of the pile foundation project. Contents of the invention [0003] A concrete pipe pile for road and bridge, comprising a circular steel pipe and an orga...
