Reinforced prestressed concrete corrugated sheet pile with rotating shaft

Abstract

The invention discloses a shaft-type reinforced prestressed concrete corrugated sheet pile, which belongs to the field of engineering construction. The technical problem solved by the invention is: traditional sheet piles are mostly cast-in-place or made on-site, the construction site is large, the maintenance time is long, and the environment around the construction site is greatly affected. Cracks, exposed tendons, etc. The technical solution of the present invention is: a rotating shaft reinforced prestressed concrete corrugated sheet pile, including a main body, a bent steel plate and concrete, the main body is interlaced with the first stirrup and the first prestressed main reinforcement to form a reinforcement cage, and the concrete is set in a steel cage. The beneficial effect of the invention is that the construction is simple, the soil retaining effect is good, the water stop effect is good, it can adapt to the slope protection of the curved river course and the complex geological structure, and it can be more convenient to drive into the hard soil layer, which is very convenient in construction and maintains the ecological balance .

Description

technical field [0001] The invention belongs to the field of engineering construction, in particular to a shaft-type reinforced prestressed concrete corrugated sheet pile. Background technique [0002] In civil engineering, the soil and water retaining structure needs to bear the external horizontal pressure load, and the structure mainly bears the bending moment, but there is often a large shear force at the sudden change of the load, and if the shear strength of the structure is not enough, shear failure will occur , such as the bottom position of the retaining structure and the horizontal support position of the foundation pit engineering, etc. Traditional retaining structures are mostly cast-in-place or fabricated on-site, which require a large construction site and long maintenance time, and have a great impact on the environment around the construction site. The soil retaining structure is prone to cracking and exposed reinforcement in the position where the shear for...

AI Technical Summary

Problems solved by technology

It solves the problems of slow construction and serious pollution of traditional sheet piles, but it also has the disadvantages of poor water-retaining performance, especially its insufficient shear strength, which is prone to deformation, and in severe cases will cause partial collapse of bank revetment works
