Structure for connecting steel pipe sheet piles, and steel pipe sheet pile structure

Abstract

Disclosed is a structure for connecting steel pipe sheet piles which is provided with: a pair of first L-shaped members which are joined, both facing inwards, to the side of a first steel pipe sheet pile; and a pair of second L-shaped members which are provided opposite the first L-shaped members and joined, both facing outwards, to the side of a second steel pipe sheet pile adjacent to the first steel pipe sheet pile. The pair of second L-shaped members is positioned inside of the pair of first L-shaped members, and concrete containing aggregate is placed in the space enclosed by the pair of first L-shaped members and the pair of second L-shaped members. The gap between the tip ends of the first L-shaped members and the second L-shaped members is smaller than the aggregate grain size, and the gap between the tip ends of the second L-shaped members and the first L-shaped members is at least twice the aggregate grain size.

Description

technical field [0001] This invention relates to the connection structure of the steel pipe sheet pile for connecting steel pipe sheet piles mutually, and the structure using the connection structure of this steel pipe sheet pile. [0002] This application claims priority based on Japanese Patent Application No. 2009-146271 for which it applied in Japan on June 19, 2009, and uses the content here. Background technique [0003] Conventionally, steel pipe sheet pile foundations and the like are constructed by connecting a plurality of steel pipe sheet piles. In general, steel pipe sheet piles are connected by so-called P-P type joining in which slit pipes provided on the outer surfaces of adjacent steel pipe sheet piles are joined to each other. [0004] Usually, in the P-P type joint, the space of the pipe to be fitted is washed and filled with plaster. Thereby, mutual connection is made reliable, and shear resistance is ensured. However, in the conventional P-P type joint...
