Abstract

The invention creatively provides a double-wall steel hanging box cofferdam system under condition of tidal reciprocating flow in a typhoon area. The double-wall steel hanging box cofferdam system comprises a cofferdam, wherein a leaning pier is arranged on the downstream of the cofferdam, and a pushing device is arranged between the leaning pier and the cofferdam; side anchor platforms are arranged on the two sides of the downstream of the cofferdam correspondingly, meanwhile, an anchor pier is arranged in water on the upstream of the cofferdam, and a ground anchor is arranged on the shore; and the anchor pier, the ground anchor and the side anchor platforms are connected and fixed to the cofferdam through stay cables. According to the double-wall steel hanging box cofferdam system, the construction scheme that the anchor pier in water is combined with the ground anchor on the shore to position the system is adopted, positioning construction is conducted in the mode that a floating crane and an anchor throwing boat are matched with manual hanging cables, the accuracy of positioning control over the cofferdam is guaranteed, the structure is stable, stress is good, and compared withtraditional anchoring positioning construction, the influence on a riverbed is reduced.

Description

technical field [0001] The invention belongs to the technical field of cofferdam positioning construction, and in particular relates to a double-wall steel suspension box cofferdam system and a positioning method under the tidal reciprocating flow condition in a typhoon area. Background technique [0002] In the positioning construction of large-scale cofferdams in deep water foundations of bridges, the traditional method is to use more conventional positioning ships and guiding ships to anchor and locate. Progress is slow. Especially in complex environments such as busy waterways, tidal reciprocating impacts, deep water and rapid currents, the construction is even more difficult, and it is difficult to ensure construction safety and quality. Contents of the invention [0003] In view of this, the present invention aims to overcome the defects in the prior art, and proposes a double-wall steel hanging box cofferdam system and positioning method under the condition of tida...
