Groove-type sheet-pile

Abstract

The invention discloses a groove-type sheet-pile. The groove-type sheet-pile comprises a platy pile body, the front face of the pile body is provided with a longitudinal groove, one side face of the pile body is provided with a longitudinal trench I, and the other side face of the pile body is provided with a strip-type bulge corresponding to the trench I. The adjacent pile joint of the groove-type sheet-pile provided by the invention is thicker, the contact area is enlarged, the butt joint is more easy, and the joint is not liable to damage; various earth-retaining pile walls are mutually fastened tightly, due to the bevel design of a pile toe, the earth-retaining pile walls are fitted with one another more tightly in a construction process, stability and safety are realized, and earth retaining and water resistance are realized in one step; the own structure of the pile body allows to arrange living things nesting holes to maintain river internal ecological balance and environment-friendliness.

Description

technical field [0001] The invention relates to a concrete pile, in particular to a grooved sheet pile. 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 permanent underground diap...

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 butt, 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, it is impossible to set biological nesting holes on the existing sheet pile structure, and when it is used in a river channel, the river bank and the river water are all Separate and block the ecological chain, affecting the ecological balance of the river itself
