Groove type plate pile and plate pile wall

Abstract

The invention discloses a groove type plate pile and a plate pile wall. The groove typo plate pile comprises a groove type pile body; a longitudinal first strip-shaped projection is arranged on one side surface of the pile body, and second strip-shaped projections are arranged on the other side surface of the pile body side by side; the first strip-shaped projection can be accommodated in a groove formed between the second strip-shaped projections; and longitudinal grooves are respectively formed in opposite positions of two side surfaces of the pile body. In the groove type plate pile and the plate pile wall, all plate piles are tightly buckled; through the inclined surface design of pile tips, all soil retaining piles in the construction process are bonded more tightly to achieve stability and safety; filter bars are arranged and matched with spaced projections, so that the traditional soil retaining effect of the plate pile wall is kept, the plate pile wall retains soil but not water, river water and underground water can be filtered for mutually flowing, and the ecological balance of rivers is kept; and meanwhile, the gap between interval sections of the projections can serve as a biologic nesting gap to nest for fishes, shrimps and microorganisms.

Description

technical field [0001] The invention relates to a sheet pile, in particular to a grooved sheet pile and a sheet pile wall. Background technique [0002] Concrete sheet pile is a new type of soil retaining, slope protection, and cofferdam material. It has changed the shortcomings of traditional water conservancy engineering materials such as high cost, poor mechanical properties, difficult construction, and unstable molding quality. It is safe, beautiful, and reliable. Features, and later maintenance is very convenient and simple. Widely used in marine engineering, flood control and disaster reduction of large rivers, regulation and reinforcement of inland rivers and lake revetments, port and wharf projects, dam emergency projects, farmland water conservancy construction, roadbed slope protection and soil retaining for roads and railways, slope protection and load-bearing for bridges and culverts, urban Engineering fields such as building foundation pit enclosure and permane...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing concrete sheet piles are sheet piles with a turned-up U-shaped section. During the construction process, adjacent sheet piles are not easy to be connected, and they are easy to shift during the piling process. Consistent, the contact area of ​​the butt joint is small, and the butt joint is easily damaged during the piling process or when it is subjected to external forces; in addition, when the existing sheet piles are used in the river, they will completely separate the river bank from the river, block the ecological chain, and affect the river itself ecological balance
