Carbon fiber cloth bag cast-in-situ anti-arch curved surface combined irregular-shaped pile and construction method thereof

A reverse arched surface, carbon fiber technology, applied in sheet pile walls, infrastructure engineering, construction and other directions, can solve the problems of poor durability of special-shaped piles, insufficient ability to resist negative friction damage, and easy damage to the pile body. The effect of negative friction resistance on the pile side, reducing the effect of soil squeeze on the pile side, and accelerating the consolidation of the soil around the pile

Abstract

The invention relates to a carbon fiber cloth bag cast-in-situ anti-arch curved surface combined irregular-shaped pile, which is characterized in that the upper part of the combined irregular-shaped pile is a round pile body while the lower part thereof is an anti-arch curved surface pile body, and the pile bottom is provided with an irregular-shaped prefabricated pile tip. A carbon fiber cloth bag wraps the outside of the pile body; a steel sleeve with a reinforcing plate is arranged on the top part of the combined irregular-shaped pile; a vertical drain body is filled in the cavity at the outer side of the round pile body; a vertical drain pipe communicated with the vertical drain body is preset in a cast-in-situ cover plate on the top part of the pile. The carbon fiber cloth bag arranged on the outer side of the pile body can reinforce the pile body, improve the stress performance of the pile body and enhance the integrity of the pile body; the section of the pile body on the lower part is an anti-arch curved surface which can prevent influence from excessive fullness of concrete of the pile body to the lateral friction of the pile; the section of the pile body on the upper part is round and can reduce the influence from the lateral negative friction of the pile to the performance of the pile body. The invention also discloses a construction method of the combined irregular-shaped pile.

Description

Technical field

[0001] The present invention involves a carbon fiber bag in the paddling of alien piles and construction methods of pouring arched curved curved surfaces. It specially involves a combination of a combination of carbon fiber cloth on the upper part of the pile body, the lower part is the anti -arch curved surface, and the carbon fiber cloth on the outside of the pile body.The field of treatment is suitable for foundation processing projects in soft land and underwriting land. Background technique

[0002] In recent years, with the increasingly tense land resources, more and more engineering projects need to be constructed in areas with deep soft foundations, insufficient land consolidation, and deep burial.Many objective conditions for engineering construction, such as large settlement deformation, low foundation capacity, and so on.In addition, because the soft land base has the characteristics of "three highs and three lows", under the influence of the upper load...
