High-strength ripple glaze casing tube foundation pile

Abstract

The invention discloses a corrugated conduit foundation pile with high strength, comprising a prefabricated pile head, a corrugated conduit, a steel reinforcement cage and concrete; wherein the section of the prefabricated pile head is like a reversed taper with a handle or a mushroom with a handle; the corrugated conduit is sheathed on the handle part of the prefabricated pile head, the steel reinforcement cage is arranged in the corrugated conduit, and the concrete is filled between the corrugated conduit and the steel reinforcement cage as well as the prefabricated pile head. As the existing foundation pile is in a prefabricated integral type while the foundation pile of the invention is formed by the prefabricated pile head, the steel reinforcement cage and the concrete by casting on field, the existing driving method of the foundation pile is fundamentally changed, thereby ensuring the quality of the foundation pile fundamentally, greatly lowering forming technical difficulty of the foundation pile, eliminating potential safety hazard of the integral prefabricated foundation pile in high-altitude operation and remarkably reducing the cost of the foundation pile.

Description

technical field [0001] The invention relates to a foundation pile, in particular to a corrugated sleeve foundation pile. Background technique [0002] In the construction process of new high-rise buildings, bridges, highways, railways and other major projects, in order to improve the strength of the building, foundation piles must be laid at an appropriate density. At present, the most conventional method of laying foundation piles includes the following steps: [0003] ① Prefabrication of concrete foundation piles is carried out according to the cross-sectional shape, size and length requirements of the engineering design, that is, prefabricated steel cages, then molded, and finally poured with concrete, and various specifications can be obtained after maintenance and demoulding. Precast concrete monolithic foundation piles; [0004] ②Transportation of prefabricated foundation piles: use engineering vehicles to transport prefabricated foundation piles of various specificat...

AI Technical Summary

Problems solved by technology

[0007] ① The final quality of the foundation piles cannot be controlled. Even if the quality of the prefabricated foundation piles is very good, it is difficult to ensure that the prefabricated foundation piles will not break when they are struck down and moved down after being moved, transported, and hammered continuously by the elevated air hammer. cracks and other defects, and when the prefabricated foundation piles have the above defects, they are still forcibly driven in, making it difficult to meet the predetermined requirements for the technical quality indicators such as the strength and overall connection performance of the entire foundation pile;

[0008] ②High labor intensity and high cost

In the whole piling process, not only the labor intensity is high, but also the cost is high. The prefabricated foundation piles must first be poured and maintained, and then transported, lifted, piled down, and hammered down;

[0009] ③Prominent safety problems in the operation process, especially the prefabricated foundation piles have serious safety hazards in the links of transportation, lifting, piling down, hammering down, etc.
