Rigid precast concrete pile with drainability

Abstract

The invention relates to a rigid precast concrete pile with drainability. The rigid precast concrete pile with the drainability comprises a pile main body, wherein a through drainage middle hole is formed in the pile main body; drainage side holes which communicate with the drainage middle hole are formed in a side wall of the pile main body; anti-rust nets which prevent soil from being extruded into the drainage side holes are arranged in the drainage side holes; a sealing top cover is arranged on the top of the pile main body; and the bottom of the pile main body is sealed. Compared with the prior art, the rigid precast concrete pile with drainability has the advantages of simple structure, safety in operation and the like; and after the rigid precast concrete pile is driven into the soil, drainage consolidation of the soil can be implemented quickly.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering test research, in particular to a rigid prefabricated concrete pile with drainage capacity. Background technique [0002] After the prefabricated concrete pile is driven into the soil with force, the pore water pressure of the soil, especially the deep soil, will rise rapidly and there is no drainage channel for rapid dissipation, so the consolidation is slow, which affects the formation speed of the bearing capacity of the foundation . At present, after the prefabricated pile body of the pile foundation is driven into the foundation by external force, high pore water pressure is often formed in the deeper soil layer. Since the pile body is generally made of concrete, the soil layer mainly depends on the radial direction of the pile body. Drainage achieves consolidation, but in fact, the drainage speed of deep soil is generally slow, which seriously affects the progress of draina...

Problems solved by technology

In this patent, a through hole is arranged on the periphery of the concrete pipe pile, and a filter core plug is arranged in the through hole. The filter core plug is stuck in the inner cavity of the through hole through an adhesive, and the pressure drop of the filter core plug is large, which is not conducive to water flow. Drain, and the filter core plug is stuck in the inner cavity of the through hole, it is easy to fall off, so that the soil enters the pipe pile; this patent does not consider the method of using negative pressure drainage; the position of the movable door has a reduction in the strength and stiffness of the pile body , no reinforcement measures were taken; moreover, the construction process of this patent is complicated and there are many production processes
