Problems solved by technology

Although bulk piles and permeable concrete piles have water permeability, they have low strength and are easy to damage. Among them, the permeable reinforced concrete piles are also very easy to corrode, and their adaptability to weak ground and their own promotion are poor.

Abstract

The invention discloses a novel decompression drainage precast pile. The novel decompression drainage precast pile comprises a novel reinforced concrete precast pile which is formed by a formwork pile-making method, and a groove is formed in the surface of the pile body in the axial direction of the pile body. A plastic drainage belt is laid in the groove and is fixed by steel bars, a connecting ring is arranged at the bottom end of a drainage belt of a first section of the pile body; hooks are arranged at the top of the tip of the precast pile and connected to the connecting ring in a hung mode and used for fixing the drainage belt and preventing the drainage belt from falling off in a pile pressing process. The novel precast pile can dissipate generated hyperstatic pore water pressure through drainage by the drainage belt in the pile pressing process and after pile pressing and accelerate consolidation of a foundation.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a novel decompression drainage prefabricated pile and a construction method thereof. Background technique [0002] With the development of society, the application of reinforced concrete prefabricated piles is becoming more and more widely. However, the soil squeezing effect produced in the process of pile sinking construction has always puzzled engineers. How to speed up the dissipation of ultra-static pore water pressure caused by pile sinking is currently research focus. In addition, in the composite foundation technology often used in foundation treatment, sometimes in order to dissipate the excess static pore water pressure, the vertical reinforcements are selected as loose material piles (such as sand piles, gravel piles) and permeable concrete piles. Although bulk piles and permeable concrete piles have water permeability, they have low strength and are easy to ...
