Permeable pipe pile system capable of accelerating consolidation and construction method thereof

Abstract

The invention discloses a permeable pipe pile system capable of accelerating consolidation. The permeable pipe pile system comprises a pile body, an gas filling device and a water draining device; the pile body is in a hollow shape, holes are evenly distributed in the pile wall of the pile body, the bottom of the pile body is sealed, and the top of the pile body is provided with a gas-tight gland; the gas filling device comprises a gas conveying pipe and a gas pump, the lower end of the gas conveying pipe penetrates through the gas-tight gland and extends into a cavity of the pile body, and the upper end of the gas conveying pipe is connected with the air pump; and the water draining device comprises a water draining pipe and a water pump, the lower end of the water draining pipe penetrates through the gas-tight gland and extends towards the bottom of the cavity of the pile body, and the upper end of the water draining pipe is connected with the water pump. The permeable pipe pile system capable of accelerating consolidation has the advantages of a permeable pipe pile and combines the characteristics of the gas filling and split technology, so that the dissipation rate of super static pore water of soil around a pile is increased, frictional resistance on the pile side is improved quickly, the requirements of the bearing cavity of the pile and the engineering service life period of a project are ensured, and the economic effect of the project is more ideal; and the construction method is simple.

Description

technical field [0001] The invention relates to the field of pile foundation engineering, in particular to an accelerated consolidation permeable pipe pile system and a construction method thereof, which are mainly suitable for soft soil foundation treatment. Background technique [0002] In recent years, with the rapid development of social economy, various projects and construction techniques have made great progress. Prefabricated reinforced concrete pipe piles have been widely used in pile foundation engineering because of their simple construction methods, ability to withstand large loads, and fast construction speed. The so-called prefabricated reinforced concrete pipe pile is a slender hollow cylindrical prefabricated concrete member of equal cross-section (referred to as pipe pile) formed by professional manufacturers using pretensioning prestressing technology and centrifugal technology, and then cured by steam. In the construction of building foundations, it is us...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a permeable pipe pile system with accelerated consolidation, so as to overcome the slow increase of the frictional resistance on the pile side after the existing pipe pile sinking, which will cause the steel bars at the pipe piles to rust and age , cracking and other problems
