Connector structure for closing steel pipe pile cofferdam structure and construction method thereof

Abstract

The invention provides a connector structure for closing a steel pipe pile cofferdam structure and a construction method thereof. The connector structure comprises a first steel pipe pile, a second steel pipe pile, I-shaped steel and water stop filling materials, wherein the first steel pipe pile and the second steel pipe pile are arranged on the two sides of a connector correspondingly, a first opening penetrating through the wall thickness of the first steel pipe pile is formed in the outer wall of the first steel pipe pile, the first opening is formed in the length direction of the first steel pipe pile, a second opening penetrating through the wall thickness of the second steel pipe pile is formed in the outer wall of the second steel pipe pile, the second opening is formed in the length direction of the second steel pipe pile, the I-shaped steel is arranged between the first steel pipe pile and the second steel pipe pile, webs of I-shaped steel are inserted into the first opening and the second opening, so that two wing plates of the I-shaped steel are inserted into the first steel pipe pile and the second steel pipe pile correspondingly and attached to the inner walls of the first steel pipe pile and the second steel pipe pile, and the water stop filling materials are arranged in the first steel pipe pile and the second steel pipe pile, so that the connectors of the steel pipe pile cofferdam structure are folded. According to the connector structure, a C + I + C type connector structure is formed, the connection mode is firm, and construction is convenient; and I-shaped steel which can be flexibly selected and is rich in variety is adopted as a closure pile.

Description

technical field [0001] The invention relates to the field of bridge engineering construction under deep water conditions, in particular to an interface structure and a construction method for closing steel pipe pile cofferdam structures. Background technique [0002] At present, with the continuous development of waterway improvement projects, there are more and more systems integrating cofferdams and support structures in the water, all of which must meet the needs of water stop, overall rigidity and strength, and ease of construction. There are also many closing interface types for steel pipe pile cofferdam structural systems, but there are certain deficiencies. [0003] To meet the stability requirements of the structure, materials with better rigidity and strength will be selected; for the problem of water-stop effect, interface types that are closely connected to each other will be selected. The more restrictive factors that exert influence, the more difficulties will ...
