Abstract

The invention discloses a construction method of a sea viaduct. The method adopts the suspension rod, the support rod and the channel structure of the south-to-north water transfer, so that the construction speed is faster, the cost is low, and the south-to-north water diversion is realized. The viaduct (three-purpose bridge) of the present invention can lead to a certain place at the source of the water source to store water, and then supply water to the three-purpose bridge through artesian flow. In this way, water-deficient areas (such as: Beijing, Tianjin) can use clean water. The water flow in the large space in the South-to-North Water Diversion Channel is enough for two big cities. High bridge construction efficiency: Because the steel materials are standardized and serialized, the above three cited patents are used in combination with this patent to form a combination. The mold and bottom plate of the present invention can be reused, and the bridge construction progress is accelerated and the cost is reduced. Reduce the construction risk and ensure the safety of workers. The steel used in the bridge, taking Bohai Bay as an example, does not exceed 400,000 tons. The deck body can be built directly on the desert and flat ground without building foundations.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a method for constructing a marine viaduct. Background technique [0002] Now the country is planning a bridge or tunnel that passes through the sea and connects the two places, but the traditional method of building bridges is difficult on the sea. At the same time, the south of China is rich in water resources, while the north of my country is relatively short of water resources. Contents of the invention [0003] The object of the present invention is to provide a method for constructing an offshore viaduct, which can realize the diversion of water from south to north, and has high construction efficiency and low cost. [0004] In order to achieve the above object, a method for constructing an offshore viaduct provided by the present invention comprises the following steps: step A. constructing a bridge pier, reserving a steel bar joint and a process boss at the top of th...
