Abstract

The invention discloses a cast-in-place arch bridge combined support structure and a construction method thereof.The cast-in-place arch bridge combined support structure comprises a first-stage bearing platform, a pile foundation, a second-stage bearing platform, an arch device and a supporting device.The first-stage bearing platform comprises a concrete bottom pile, a supporting column, a reinforcing device and a fixing rod, a U-shaped groove is formed in the top of the concrete bottom pile, and a protruding block is inserted into the bottom of an inner cavity of the U-shaped groove; the supporting column is inserted into the top of the concrete bottom pile. The concrete bottom piles are poured at the bottom of the riverbed, the supporting columns are spliced to the concrete bottom piles, the fixing rods and the limiting rods are used for limiting the supporting columns, and the concrete bottom piles can provide a firm supporting point for the first-stage bearing platform and the second-stage bearing platform so as to facilitate pouring of the arch bridge; in addition, various devices can be conveniently disassembled after the arch bridge is poured, the concrete bottom piles under the water surface do not affect the flowing speed of passing ships and water flow, and therefore the construction safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to a cast-in-situ arch bridge composite support structure and a construction method thereof. Background technique [0002] Cast-in-situ reinforced concrete arch bridges are often selected as the main type of urban river-crossing bridges because of their large spanning capacity, high bearing capacity, and magnificent bridge shape. The bracket method is the main construction method for cast-in-situ arch bridges. In recent years, the requirements for environmental protection and water conservation have become more and more stringent. In particular, the construction of islands to narrow riverbeds is strictly prohibited in urban river-related projects, so as to avoid hidden dangers of soil erosion, water pollution, and safe flood season. [0003] The serious problem in the construction of the existing arch bridge is that the column is inserted into the river bed to ...
