Pier column prefabrication splicing building technology

Abstract

The invention provides a pier column pre-casting splicing construction technique working method, which is characterized in that: on a land construction site, a pier body of the whole bridge pier is pre-cast by segments, pier body end heads of each segment are buried with outwardly-extending reinforcement bars, and all segments are transferred to the pier construction site for pier assembly. The working method has the advantages of having light bridge piers, reducing the number of projects, saving manpower, lowering construction costs, having good construction quality and quick construction, solving the problems of reliability, safety, anti-crack property and durability between pier columns pre-cast by segments and between the pier columns and a bearing platform connecting structure, reducing the influence of natural conditions on construction period, reducing construction cost and construction risk, reducing the number of cast-in-situ concrete and equipment such as a hoisting machine and the like and effectively saving cost. Due to the advantages of the splicing type bridge pier and the development of various high strength concrete materials in recent years, the working method is applied to water bridges with large scale, multiple bridge spans, adverse natural environment, and difficult construction due to the influence of wind, wave, current, rain and fog.

Description

technical field [0001] The invention belongs to the construction of bridge piers, in particular to a prefabricated splicing construction method of pier columns. technical background [0002] In the past, the traditional construction method of bridge piers was to place steel sleeves and cast-in-place reinforced concrete on the spot in the water, and build them up bit by bit in the water. Such construction is inconvenient, the period is long, and various quality problems will be caused by the influence of the weather. Contents of the invention [0003] The invention provides a prefabricated splicing construction method of pier columns. It is based on the fact that in the past ten years, with the continuous emergence of new materials and the development of bridge design technology, the pier structure has developed towards the direction of light weight, high strength and rapid construction. The development of high-toughness, high-density and high-durability concrete provides ...
