Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a construction method for a temporary cross-sea steel trestle bridge in the shape of a zigzag in view of the deficiencies in the above-mentioned prior art. A temporary steel trestle in the shape of a zigzag is erected across the sea. The main body of the steel trestle and the channel-type support trestle together can provide a safe and reliable construction platform for the construction of the bridge to be built. The construction method of the temporary steel trestle is simple and convenient for construction, which solves the problem The problem of difficult construction of temporary steel trestle bridges in the sea area can shorten the construction period

Abstract

The invention discloses a construction method of an omega-shaped cross-sea temporary steel trestle. The construction method comprises the steps that 1, a bridge abutment and a steel approach bridge are constructed; 2, two connecting bridge sections are constructed; 3, two transition bridge sections are constructed; and 4, a main bridge section is constructed. The omega-shaped cross-sea temporary steel trestle is erected in a sea-crossing mode under the condition that the geographical positions of an existing wharf, a first dam and a second dam are combined, a steel trestle body and a channel type supporting trestle can jointly provide a safe and reliable construction platform for construction of a bridge to be built, and the construction method of the temporary steel trestle is simple and convenient to construct. The problem that a temporary steel trestle in a super-large-span sea area is difficult to construct is solved, and the construction period can be shortened.

Description

technical field [0001] The invention belongs to the technical field of construction of a temporary steel trestle bridge, and in particular relates to a construction method of a several-shaped temporary steel trestle bridge across the sea. Background technique [0002] The bridges to be built include the main span bridge to be built, the first approach bridge to be built and the second approach bridge to be built. The total length of the bridge to be built is 1775.8m, the total length of the first approach bridge to be built is 720m, and the total length of the second approach bridge to be built For the second approach bridge to be built and the first approach bridge to be built with a total length of more than 500m, according to the actual situation of the project and the overall construction arrangement, it is necessary to lay bridges along the direction of the bridge to be built between the east and west bank embankments during the construction process. A temporary steel t...
