Embodiment Construction

[0054] Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 ~ Figure 3 It is a plan view of the first to third embodiments of the steel pipe sheet pile caisson foundation of the present invention. First, it will be described from one unit of the H-steel connection type steel pipe sheet pile used in the present invention, as follows: Figure 4 As shown, in the H-steel connection type steel pipe sheet pile 1, the H-shaped steel 4 is used as a tie rod member, which makes the steel pipes 2 arranged in parallel weld together with the flange edge at the periphery of each steel pipe 2, and only the H-shaped steel The width of 4 is welded integrally at intervals. In addition, an H steel external thread pipe joint 7 and an H steel internal thread pipe joint 8 are provided on the opposite side to the mutual welding.

[0055] The H-shaped steel 4 can be rolled from steel, and can also be assembled separately through appropriate ...

Abstract

A twin-type steel pipe sheet-pile well foundation and a twin-type steel pipe sheet-pile used therefor are provided to improve economical effects and to remarkably improve shear resistance of a connection part. A twin-type steel pipe sheet-pile well foundation is formed by joining several twin-type steel pipe sheet-piles(1) in a closed shape while combining connection members. In the twin-type steel pipe sheet-pile, an H-shaped steel male connection part(7) or female connection part(8) as a connection part is arranged to an H-shaped steel connection steel pipe wherein steel pipes(2) are integrally connected by the H-shaped steel connection member the flange edges of which are combined to the periphery of each steel pipe. The H-shaped steel male connection part shakes to be combined to a space surrounded by the flange inside of the H-shaped female connection part and the wave face. The H-shaped male connection part or H-shaped female connection part is inclined at a proper angle with respect to the H-shaped steel connection member in a projecting direction, to enable combination in a closed shape.

Description

technical field [0001] The invention relates to steel pipe sheet pile caisson foundations used in construction of bridge foundations and the steel pipe sheet piles used therein. Background technique [0002] Steel sheet piles have been used in conventional soil retaining construction methods for excavating foundations. Compared with steel sheet piles, steel pipe sheet piles have a longer length and greater section rigidity. Showa 38 (1963) Steel pipe sheet piles were first used in sheet pile piers in Japan. Afterwards, Showa 41 (1966) steel pipe sheet pile foundation was used in the foundation of an ore smelting furnace, which made full use of the characteristics of steel pipe sheet piles. [0003] This form of foundation is well received for ensuring construction performance in weak ground with deep support layers. It was used as the foundation of the Ishikari Riverguchi Bridge in Showa 44 (1969) as a bridge foundation. Steel pipe sheet pile foundation In the underwater...
