Fiber-reinforced confined pipe gravel pressure-bearing pile and preparation method thereof

Abstract

The invention discloses a fiber-reinforced confined pipe gravel pressure-bearing pile and a preparation method thereof, and belongs to the field of civil engineering material manufacturing. Accordingto the fiber-reinforced confined pipe gravel pressure-bearing pile and the preparation method thereof, a fiber-reinforced confined pipe is prefabricated and formed by adopting a centrifugal process, an artificial borehole is formed during site construction, the fiber-reinforced confined pipe is put inside, and then gravel fills the pipe and is subjected to vibration preloading compaction so as toobtain the fiber-reinforced confined pipe gravel pile. The fiber-reinforced confined pipe gravel pressure-bearing pile and the preparation method thereof have the advantages that one one hand, an original loose gravel body can be compact in structure and can play a bearing role, on the other hand, the gravel body is stressed in three directions in the pressure bearing process, the mechanical property can be greatly exerted, and meanwhile, the internal gravel body restrains the local buckling and breaking phenomena of the fiber-reinforced confined pipe, so that the internal gravel body can havethe same vertical bearing capacity as a cast-in-place or prefabricated reinforced concrete pile through the two coordination effects; and the fiber-reinforced confined pipe gravel pressure-bearing pile is reasonable in structure, the mechanical property of the material can be brought into full play, the gravel serves as the main material, and the economic advantages are obvious.

Description

technical field [0001] The invention relates to a crushed stone pressure pile, in particular to a fiber reinforced constrained tube crushed stone pressure pile, which belongs to the technical field of civil engineering pile foundations. Background technique [0002] With the development of the city, the building land is becoming more and more tense, and various high-rise, super high-rise buildings with complex structures are rising, and the requirements for the foundation are getting higher and higher. As an important form of foundation, pile foundation is widely used because it can pass through the entire weak foundation soil layer to the soil layer with good geology, overcome the negative impact brought by bad soil layer and provide strong bearing capacity. It is used in foundations of various buildings and structures. [0003] The quality of the pile body, which is the basic component unit of the pile foundation, directly affects the bearing capacity of the pile foundati...

AI Technical Summary

Problems solved by technology

Although these piles can provide good bearing capacity, due to their different production and construction techniques, there are certain differences in their relevant performance parameters.

For cast-in-situ piles and on-site prefabricated solid piles, although their bearing capacity can meet the relevant requirements, the quality of piles is easily affected by on-site construction conditions such as personnel, equipment, and climate.
