Embodiment Construction

[0013] A cable protection pipe crossing bridge structure, including a bridge pier arranged in a river and a cable bridge spanning the river, an arched steel frame is installed on the bridge pier, the cable bridge passes through the arched steel frame, and the arched The steel frame is fixed with the cable tray by cable-stayed cables.

[0014] The advantages of using cable-stayed cable bridge spanning are: through the calculation and analysis of trusses, arched cables, arched diagonal braces, and cable-stayed bridges, the cost of cable-stayed bridges is optimal. In addition, the foundations on both sides of cable-stayed bridges are shallow , The small footprint can reduce the construction surface on both sides of the river, and the buried depth is above the water surface. The construction can largely avoid the problem of river embankment flood protection. It has good adaptability to the site. The cable-stayed bridge is beautiful in shape, strong in modernity, and harmonious with...

Abstract

The invention discloses a cable protection tube bridge crossing structure, which comprises a pier arranged in a river and a cable bridge crossing over the river, wherein an arc steel frame is arranged on the pier; the cable bridge passes through the arc steel frame; the arc steel frame is fixed with the cable bridge via cable-stayed ropes; the cable bridge is provided with a protection tube clamp for fixing the cable protection tube; the protection tube clamp comprises a plurality of parallelly-arranged clamping strips vertically; the cable protection tubes are fixed between vertical adjacent clamping strips side by side; and each clamping strip is provided with an arc-shaped positioning groove for positioning the outer circle of the cable protection tube. The protection tube clamp is arranged on the cable bridge for fixing the cable protection tube, and the protection tube can be ensured to be reliably and tidily fixed in the bridge.

Description

technical field [0001] The invention relates to cable construction technology, in particular to a cable protection tube bridge structure. Background technique [0002] There are many rivers in the south, and many cables must pass through the rivers. Many rivers are located in urban areas, and the construction areas at both ends of the crossing rivers are small. The traditional cable protection tube bridge structure makes construction difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bridge structure for cable protection tubes, which is convenient for construction and ensures that the cable protection tubes are fixed reliably and neatly. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a cable protection pipe crossing bridge structure, including bridge piers in the river and cable bridges across the river, arched steel fra...
