no. 1 approach

[0022] First implementation: see Figure 1-2 , an island building structure used for the construction of bridges across rivers, comprising a foundation stone 1, a cofferdam 2 is fixedly connected to the edge of the top of the foundation stone 1, and a reinforcing plate 9 is fixedly connected to the bottom of the left and right sides of the cofferdam 2, and the reinforcing plate 9 The bottom of the foundation stone 1 is fixedly connected to the top of the foundation stone 1, and the cofferdam 2 is reinforced by setting the reinforcing plate 9, so that the connection between the foundation stone 1 and the foundation stone 1 is more stable. The top of the foundation stone 1 is fixedly connected with the base 3, and the The midpoint is fixedly connected with the main pier 4, the surface of the main pier 4 is fixedly connected with the clay wall 5, the surface of the clay wall 5 is fixedly connected with the steel cage protective layer 6, and the bottoms of the clay wall 5 and the s...

no. 2 approach

[0026] Second embodiment: with reference to what is shown in claim 1, an island building structure used for cross-river bridge construction includes a foundation stone 1, and the edge of the top of the foundation stone 1 is fixedly connected with a cofferdam 2, and the corner of the foundation stone 1 The top is fixedly connected with a base 3, and the midpoint of the top of the base 3 is fixedly connected with a main pier 4, and the surface of the main pier 4 is fixedly connected with a clay wall 5, and the surface of the clay wall 5 is fixedly connected with a reinforcement cage for protection. Layer 6, the bottom of the clay wall 5 and the steel cage protective layer 6 are fixedly connected with the top of the base 3, the top of the main pier 4 is fixedly connected with a cap 7, and the bottom of the cap 7 is connected with the clay wall 5 It is fixedly connected with the top of the steel cage protective layer 6, and the tops of the left and right sides of the inner wall of ...

Abstract

The invention discloses an island building structure for across-riverway bridge construction. The island building structure comprises a footstone, a cofferdam is fixedly connected to the edge of the top of the footstone, a base is fixedly connected to the top of the footstone, a main pier is fixedly connected to the midpoint of the top of the base, a clay wall is fixedly connected to the surface of the main pier, the surface of the clay wall is fixedly connected with a reinforcing cage protective layer, and the bottom of the clay wall and the bottom of the reinforcing cage protective layer areboth fixedly connected with the top of the base. Through cooperation of the cofferdam, the base, the main pier, the clay wall, the reinforcing cage protective layer, a pile cap, a first connecting block, a hollow column, a chute, a slider, a threaded rod, a threaded sleeve, a connecting rod, an annular groove, a limiting block and a second connecting block, the high-stability island building structure for across-riverway bridge construction is realized; and through adjustment of a connecting device, the outward prestressing force of the cofferdam can be increased, the structure is firmer during outside pressure resisting, and the adaptability is higher.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an island-building structure used for bridge construction across rivers. Background technique [0002] Bridge construction refers to the process of building a bridge according to the design content; it mainly refers to bridge construction technology, construction organization, construction management, construction quality, etc., the construction of bridgehead approach roads and diversion buildings during construction, and the river beach embankment of bridgehead approach roads Part of it should be filled with highly permeable soil, and protected by masonry to prevent erosion. Most of the diversion structures are built on the spot with firewood rafts, gabions, stone masonry or concrete according to the design in the dry season. [0003] With the rapid development and development of the economy, the importance of highway and large-scale bridge construction is also highl...
